Answer:
11k^2 (k - 7)(k - 1)
Step-by-step explanation:
The highest common factor is
11k^2
Using the distributive property we get at least 2 factors.
11k^2 ( k^2 - 8k + 7)
The second factor reduces yet again.
11k^2 (k - 7)(k - 1)
Answer:
11k^2(k−7)(k−1)
Step-by-step explanation:
11k^4 − 88k^3 + 77k^2
Factor out 11.
11(k^4-8k^3+7k^2)
Consider k^4-8k^3+7k^2. Factor out k^2.
k^2(k^2−8k+7)
Consider k^2 −8k+7. Factor the expression by grouping. First, the expression needs to be rewritten as k^2+ak+bk+7. To find a and b, set up a system to be solved.
a+b=−8
ab=1×7=7
Since ab is positive, a and b have the same sign. Since a+b is negative, a and b are both negative. The only such pair is the system solution.
a=−7
b=−1
Rewrite k^2−8k+7 as (k^2−7k)+(−k+7).
(k^2−7k)+(−k+7)
Factor out k in the first and −1 in the second group.
k(k−7)−(k−7)
Factor out common term k−7 by using distributive property.
(k−7)(k−1)
Rewrite the complete factored expression.
11k^2(k−7)(k−1)

Which of the following sets of side
lengths would not form a triangle?
A 29, 39, 69
B 29, 38, 49
C 29, 41, 19
D 29, 37, 10
Answer:
A
Step-by-step explanation:
Because 29+39=68
68<69
therefore this would not make a triangle!
Answer:
A.
Step-by-step explanation:
29 + 39 = 68 which is less than 69 so A is not a triangle.
decide whether the triangle is a right triangle.
Answer:
no it is not a right angle triangle

Use the information to answer the question.
There are 2.54 centimeters in 1 inch. There are 100 centimeters in 1 meter.
To the nearest meter, how many meters are in 275 inches? Enter the answer in the box.
meters
0
Answer:
7 m
Step-by-step explanation:
We are told that;
100 cm = 1 m
Thus; 2.54 cm = 2.54 × 1/100 = 0.0254 m
This means that;
1 inch = 0.0254 m
Thus; 275 inches will give; 275 × 0.0254/1 = 6.985 m
Approximating to the nearest metre gives 7 m

(-1,-4) and (-5,-8)
B.
(-1,2) and (-5,-2)
C.
(1,4) and (5,8)
D.
(-1,-2) and (-5,2)
Answer:
B. (-1,2) and (-5,-2)
Step-by-step explanation:
Substitute x + 3 in for y in the second equation. you get
[tex]x + 3 = x^{2} + 7x + 8\\x^{2} + 6x + 5 = 0[/tex]
(x + 1)(x + 5) = 0
x + 1 = 0 or x + 5 = 0
x = - 1 or x = -5
Using the first equation, let x = -1 and x = -5 in order to get the corresponding values for y
y = -1 + 3 = 2 and y = -5 + 3 = -2
So, B is the correct answer.

Actually Welcome to the Concept of the Surface areas and Volumes.
Since, we know that the lateral area of a Right circular cone is given as,
AL = πrl
here, l = slant height , r = radius of the circular base.
so now, we have to find first slant height to get the lateral surface area,
[tex]l \: = \sqrt{ {r}^{2} + {h}^{2} } [/tex]
here, r = 8 cm and h = 15,
hence,
[tex]l \: = \sqrt{64 + 225} = \sqrt{289} = 17cm[/tex]
hence, now we apply the formula,
AL = π(8) (17) cm^2
===> AL = 136 π cm^2

The equation k = 1.6d gives an approximate relationship between d miles and k kilometers. The distance between Columbus, Ohio, and Des Moines, Iowa, is 665 miles. Express the distance in kilometers.
A.
1,064 km
B.
415.6 km
C.
666.6 km
D.
663.4 km
[tex]k = 1.6d[/tex]
[tex]k = 1.6(665)[/tex]
[tex]k = 1064[/tex]
The distance is 1064 km.
Answer:
A. 1,064 km
Step-by-step explanation:
1 Mile is 1,6 Kilometers
430 Miles = 688 Kilometers (430 * 1,6)
665 Miles = 1064 Kilometers (665 * 1,6)
1- 1.6(430)= 688 Km
2. 1.6(665)=1064 Km
Using 1.6 as the consant then 430* 1.6 = 688 Km
655 * 1.6 = 1048Km
if i understand what you need properly, all you do is multiply the miles x 1.6 and you will get k. so 430miles x 1.6 = 688k
and 665miles x 1.6 = 1064k

Luna has n colored cards. Some are red and some are blue. The ratio of the number of red cards
to the number of blue cards is 5:2. Luna has 60 red cards.
Find an
Answer:
n = 84 and there are 24 blue cards
Step-by-step explanation:
I'm guessing you're either trying to find n or the number of blue cards.
To find the number of blue cards:
Luna has 60 red cards and the ratio of red to blue cards is 5:2.
If you divide 60 by 5 (the number of red cards divided by the ratio for red cards) you get 12, which would be 1 in the ratio. The number in the ratio for blue cards is 2, so multiply 12 by 2 and you get 24. Therefore, the number of blue cards is 24.
If the explanation is confusing (which I know it is, sorry) you can look at it like this, and this is also a check:
The ratio of red to blue cards can be written as 5/2. If you do 5 ÷ 2, you get 2.5 and if you divide 60/24, you get 2.5
To find n, the number of cards Luna has, just add the number of red cards and the number of blue cards: 60 + 24 = 84

A chemical solution contains 4% alcohol. If there is 24 ml of alcohol, what is the volume of the solution?
Answer: 600 ml
Step-by-step explanation:
Let the volume of the solution be represented by x.
Therefore, we can form an equation based on the information given which will be:
= 4% × x = 24.
4/100 × x = 24.
0.04 × x = 24
0.04x = 24
x = 24/0.04
x = 600
The volume of the solution is 600ml

The track team sold 40 t-shirts. Short sleeve t-shirts sold for $9.90 and long sleeve
t-shirts sold for $12.75. In all, $421.65 was taken in.
How many short sleeve t-shirts were sold?
Answer:
The track team sold 31 short sleeved t-shirts.
Step-by-step explanation:
If there were 40 t-shirts sold, then you'd have to find how many short sleeved and long sleeved t-shirts were sold to get the amount of money made. Basically, all I did was start with 20:20. I multiplied the cost of each type of shirt by 20, however, the money from selling long sleeved t-shirts is a lot more than the actually amount. So then, I went to 30:10 with short sleeved and then long sleeved. The amount (when added together) was pretty close to the actual amount but it was still a tiny bit higher than the actual. So, I did 31:9 and the amount came out right.

What is the area of the polygon ?
Answer:
C) 99 in²
Step-by-step explanation:
you can divide this shape by drawing a horizontal line to create a 4x12" rectangle and a trapezoid with a height of (10-4) in and bases of 12 and 5"
area of rectangle: 12 x 4 = 48
area of trapezoid: 1/2(6)(12+5) = 3(17) = 51
total area = 48 + 51
total area = 99 in²
Answer:
C. 99
Step-by-step explanation:
First, we can split it into two rectangles and a right triangle: (see the image below)
The first rectangle has sides of 5, 10, 5, and 10.
The second has sides of 4, 7, 4, and 7.
The third has sides of 7, 6, and √85.
The first rectangle:
Because opposite sides are congruent in a rectangle, we know that the side across of the measure of 5 is also 5. The side across from 10 is also 10.
The second rectangle:
From the side with a measure of 4, draw a line across to meet the side of the first rectangle.
Because opposite sides are congruent, we know the other side is 4.
Because the whole entire bottom is 12, and the bottom of the first rectangle is 5, the side of the second rectangle must be 7.
This makes the other sides also 7.
The right triangle:
Because the lines are all perpendicular (indicated by right angle symbol), this is a right triangle.
We know that one of the sides is 7 (because of opposite sides being congruent in a rectangle). The whole side is the side of the first rectangle, so it's 10. That means that the other side of the right triangle is 6.
With the Pythagorean Theorem, we can find that the hypotenuse is √85.
Area of First Rectangle: A = l h
A = (5) (10)
A = 50
Area of Second Rectangle: A = l h
A = (4) (7)
A = 28
Area of Right Triangle: A = (1/2) (b) (h)
A = (1/2) (7) (6)
A = 21
21 + 28 + 50 = Area
Area = 99

Answer:
10. 264
11. 13
Step-by-step explanation:
10- When we are doing perimeter we add all the sides together. Since it's a square this time, we know all the sides are even at 66ft.
66+66+66+66= 264
I added 4 times for each side we have and we get the perimeter of 264
11- When dealing with area, all we need is two numbers. To get area we multiply the length and width. If we have the area and want either length or width, we can still easily do that. All we have to do is divide the area from your given number.
65 divided by 5 is 13
Area divided by Length is Width
Answer:
#10= 264
#11= 13
Step-by-step explanation:
#10: We can see that this is a square because it says so in the question so we can assume that if it is a square then all the lengths and widths are 66 feet. 4(66) = 264 or 66+66+66+66 = 264
#11: 65/5 = 13 because it is dealing with area, simply just divide the total of area by the known length to get the width.
A 20 feet tree casts a shadow that is 32 feet long. What is the distance from the top of the tree to the tip of the shadow?
Answer:
37.7359
Step-by-step explanation:
first you visualize the shape created
if you visualize it... it will look like a right angled triangle
and we are looking for the longest side
remember the pythagoras theorem c^2= a^2 + b^2
in this case we are looking for c
a^2= 20^2
b^2= 32^2
400+ 1024= 1424
therefore c^2= 1424
then you square root 1424
to get 37.7359
note- the answer is solely based on the information given
