Answer:
40%
Step-by-step explanation:
it's easiest to get a percentage from 100, multiplying 25 by 4 gives you 100 so if you do that then multiply 10 by four to make the equation even that will give you the answer
A 36 ounce box of cereal costs $3.50. Find the unit price.
$0.0972
I think.
Um this is to make it long enough to post. lol
Answer:
Approximately $0.10 per ounce
Step-by-step explanation:
Hi! :) I'm assuming this problem is asking for the price per ounce? If not, I apologize.
So, in order to determine the price of cereal per ounce we would simply divide $3.50 by 36 to find the cost per ounce.
$3.50 / 36 = approximately $0.09722222 which we can round up to $0.10.
Hope this helps!
have to state if the triangles are similar or not.
2. You have to provide the postulate used if similar.
3. You have to complete the similarity statement. 4. You have to support your answers with work.
Answer:
Step-by-step explanation:
10). 1). Both the triangles are not similar.
2). For the similarity of two triangles, corresponding sides of the triangles should be proportional and the included angles should be equal in measure.
Although the angle given is equal but the corresponding sides of the triangles are not proportional, triangles are not similar.
[tex]\frac{UW}{HF}= \frac{UV}{GF}[/tex] (For similar triangles)
[tex]\frac{9}{21}= \frac{18}{42}[/tex]
[tex]\frac{3}{7}=\frac{6}{7}[/tex]
But [tex]\frac{3}{7}\neq \frac{6}{7}[/tex] therefore, both the triangles are not similar.
11). In ΔTUV and ΔCDE,
If the given triangles are similar, their corresponding sides will be proportional and the included angle will be equal in measure.
∠C ≅ ∠T [Given]
[tex]\frac{TU}{CD}= \frac{UV}{DE}[/tex]
[tex]\frac{30}{10}=\frac{27}{9}[/tex]
3 = 3
True.
Therefore, ΔTUV ~ ΔCDE (By SAS postulate of similarity]
Which of the following angles DO NOT have equal measure when a pair of parallel lines is crossed by a transversal?
how do i solve for y? what’s the answer?
Answer:
Hello!
A parallel line must equal 180 degrees. Thus, 6y plus 120 degrees must equal 180. First, subtract 120 from 180. This gives us 60. To find y, we divide 60 by 60. This gives us 10. So, our answer is y=10. This means that y is being multiplied 6 times to equal 60.

Student A's scores have a standard deviation of 5.4 and Student B's scores have a standard deviation of 10.6. What does Student B's higher standard deviation mean of his/her test scores?
Answer:
Student B's score has a greater variation from the mean than student A's score
Step-by-step explanation:
Student A : standard deviation = 5.4
Student B : standard deviation = 10.6
The standard deviation is used to measure the degree of variability of a measured value from the mean or average value of the set. The higher the value of standard deviation, the greater the variabilityabiut the mean. Hence for the question given above, Student B's score varies greatly from the mean Than student A's score.

Evaluate the expression when a=−15 and b=−5.
hat would -
A divided by b = ?
be?
Answer:
3Step-by-step explanation:
Given the following values a=−15 and b=−5.
We are to find a/b
a/b = -15/-5
a/b = 15/3
a/b = 5*3/5*1
a/b = 5/5 * 3
a/b = 1*3
a/b = 3
Hence a divided b will be 3

In triangle ABC, point D is the centroid, and BD = 6. Find BE.
Given:
In triangle ABC, point D is the centroid, and BD = 6.
To find:
The measure of side BE.
Solution:
We know that the centroid divides each median in 2:1.
In the given figure BE is a median and point D is the centroid. It means point D divides the segment BE in 2:1.
Let BD and DE are 2x and x respectively.
We have, BD = 6 units.
[tex]2x=6[/tex]
[tex]x=\dfrac{6}{2}[/tex]
[tex]x=3[/tex]
Now,
[tex]BE=BD+DE[/tex]
[tex]BE=6+x[/tex]
[tex]BE=6+3[/tex]
[tex]BE=9[/tex]
Therefore, the measure of side BE is 9 units.
Plss help me, I have to find area
Answer:
C: 191.
Step-by-step explanation:
The total area of this is a little less than 15 x (3+4+10) = 15 x 17 = 255.
So then we subtract that by 36, which is the rectangle that is missing from the shape. So 255-36 = 219.
So now we have to guess. The triangle seems a little small, so it has to be the largest option, which is C: 191.
Divide. Express your answer in simplest form.

The length of a rectangle is 4 meters less than twice its width. The are of a rectangle is 70m^2. Find the dimensions of the rectangle.
Answer:
The length is 7 m
The width is 10 m
Step-by-step explanation:
length = x
width = 2x - 4
length * width = area
It is given that the area is 70 [tex]m^{2}[/tex]
From there
x * (2x - 4) = 70
[tex]2x^{2}[/tex] - 4x = 70
[tex]2x^{2}[/tex] - 4x - 70 = 0
[tex]x^{2}[/tex] - 2x - 35 = 0
Now we have a quadratic equation, which is a[tex]x^{2}[/tex] + bx + c = 0, where a [tex]\neq[/tex] 0
In this equation a = 1, b = -2 and c = -35
Discriminant (D) formula is b² - 4ac
D = [tex]-2^{2}[/tex] - 4 * 1 * (-35) = 144 > 0
This discriminant is more than 0, so there are two possible x
Their formulas are [tex]\frac{- b - \sqrt{D} }{2a}[/tex] and [tex]\frac{- b + \sqrt{D} }{2a}[/tex]
[tex]x_{1}[/tex] = [tex]\frac{- (-2) - \sqrt{144} }{2}[/tex] = -5 < 0 (the length of the rectangle has to be more than 0, so we don't use this x)
[tex]x_{2}[/tex] = [tex]\frac{- (-2) + \sqrt{144} }{2}[/tex] = 7 > 0 (this one is right)
Calculating the dimensions
length = x = 7 (m)
width = 2x - 4 = 2 * 7 - 4 = 10 (m)
factor completely6x2+8x+2. Fill in the blanks using the correct sign: 2(3x+ )(x+ )
Answer:
2(3x+1)(x+1)
Step-by-step explanation:
First, we factor out the common term, which is 2.
2(3x²+4x+1)
Then, we factor the polynomial inside the parenthesis.
2(3x+1)(x+1)
Answer:
2(3x + 1)(x + 1)
Step-by-step explanation:
Given
6x² + 8x + 2 ← factor out 2 from each term
= 2(3x² + 4x + 1) ← factor the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term
product = 3 × 1 = 3 and sum = 4
The factors are + 3 and + 1
Use these factors to split the x- term
3x² + 3x + x + 1 ( factor the first/second and third/fourth terms )
= 3x(x + 1) + 1(x + 1) ← factor out (x + 1) from each term
= (3x + 1)(x + 1) , then
3x² + 4x + 1 = (3x + 1)(x + 1)
and
6x² + 8x + 2 = 2(3x + 1)(x + 1) ← in factored form

The ratio of two number is 4:9.When 5 is subtracted from each of them,the new ratio becomes 3:8. Find the numbers.
Answer:
The numbers are 20 and 45
Step-by-step explanation:
Let the two numbers be a and b
The ratio of the two is 4:9
That means;
a/b = 4/9
9a = 4b •••••(i)
secondly;
Subtracting 5 from each gives a ratio of 3:8
(a-5)/(b-5) = 3/8
8(a-5) = 3(b-5)
8a - 40 = 3b - 15
3b - 15 + 40 = 8a
3b + 25 = 8a
a = (3b + 25)/8 •••(ii)
Insert this into 1
9(3b + 25)/8 = 4b
27b + 225 = 32b
32b - 27b = 225
5b = 225
b = 225/5
b = 45
From i;
9a = 4b
9a = 4 * 45
a = 4 * 45/9
a = 20

Question 12
If a car tries to stop on ice, the distance the car slides can be modeled by the equation s= 50d + 25 where s stands
for speed in mph and d stands for distance in feet. What distance will you slide if your car is traveling at a speed of
55 mph?
[tex]s = 50d + 25[/tex]
[tex]55 = 50d + 25[/tex]
[tex]55 - 25 = 50d + 25 - 25[/tex]
[tex]30 = 50d[/tex]
[tex] \frac{30}{50} = \frac{50d}{50} [/tex]
[tex]0.6 = d[/tex]
Your car would slide a distance of 0.6 feet.
