Answer:
The plastic model is 50 meters tall
Step-by-step explanation:
Here, we want to know how tall is the plastic model
In the plastic model 10 m represents 65 meters
then x meters plastic = 325 m real
10 * 325 = 65 * x
3250 = 65x
x = 3250/65
x = 50 meters
{(5²)} ³×5⁴}÷5⁷ simplify and express the following as exponent
Answer:
The answer is 5³.
Step-by-step explanation:
You have to apply Indices Law :
[tex] {a}^{m} \times {a}^{n} ⇒ {a}^{m + n} [/tex]
[tex] {a}^{m} \div {a}^{n}⇒ {a}^{m - n} [/tex]
[tex] { ({a}^{m} )}^{n} = {a}^{mn} [/tex]
So for this question :
[tex]( {( {5}^{2}) }^{3} \times {5}^{4} ) \div {5}^{7} [/tex]
[tex] = ( {5}^{6} \times {5}^{4} ) \div {5}^{7} [/tex]
[tex] = {5}^{10} \div {5}^{7} [/tex]
[tex] = {5}^{3} [/tex]

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a $7.50 delivery fee and $14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60
Each pizza is cut into 8 slices, and she wonders how many total slices she can afford.
Let P represent the number of pizzas that Jacque buys.
What is the inequality ?
Answer:
7.50 + 14P < 60; 24 slices
Step-by-step explanation:
What is the slope of the line represented by the equation – 5x + 2y = 10
Answer:
5/2 or 2.5
Step-by-step explanation:
use the equation y=mx+c
where m=slope=coefficient of x
-5x+2y=10
2y=5x+10
2y/2= 5x/2+ 10/2
y= 5x/2+ 5
Therefore the slope of the line is 5/2 or 2.5
The measure of angle JKL can be represented using the expression 3x + 5.
Answer:
The measure of ∠JKL is 65°
Step-by-step explanation:
Consider the provided diagram.
We need to find the degree measure of ∠JKL.
It is given that ∠JKM=45° and ∠MKL=x°
Also it is given that the measure of angle JKL can be represented using the expression 3x + 5.
Thus ∠JKL=3x+5
From the figure it can be concluded that ∠JKL is equal to the sum of ∠JKM and ∠MKL
This can be written as:
∠JKL = ∠JKM+∠MKL
Substitute the respective values in the above equation.
3x+5 = 45+x
Subtract x and 5 from both the sides.
3x+5-x-5 = 45+x-x-5
2x = 40
x = 20
Thus, the measure of ∠MKL=20°
Substitute the value of x in ∠JKL = 3x+5.
∠JKL = 3(20)+5
∠JKL = 60+5
∠JKL = 65
Hence, the measure of ∠JKL is 65°

To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

She serves the soup in 280ml portions, correct to the nearest 10ml.
22 people order this soup.
Does joy definitely have enough soup to serve 22 people?
Show how you decide.
Your final line must be written as,Joy definitely does have enough soup or Joy may not have enough soup.
I tried so hard to answer it but it isn't right so if you give me an answer please explain it so next time I will have a similar type of question I will know how to do it.
This is what i tried
6250:275=22.8 (1 d.p)
Answer:
She can serve up to 22 people
Step-by-step explanation:
Given that the total amount of soup that Joy makes in liters is 6.5L
also that the portions are in ml
280ml to liters we have 280/1000= 0.28L
our aim is to know weather 6.5L divided by 0.28L can be up to 22
let us try it out
6.5/0.28= 23.214
we have 23.
Therefore the 6.5L can serve up to 22 portions of 280ml in 6.5 L of soup

Step-by-step explanation:
Large reusable bottles cost $4 more than small ones. Eight large bottles cost $24 less than
A small bottle costs $14.
To solve the problem, the equation would be this:
Let s represent a small bottle. Since one large bottle is $4 more than a small one, you would write out (4+s). Then, multiply it by 8 to find one side of the equation, and get 8(4+s). To write out the right side of the equation, you would write out 12s to represent 12 small bottles, and subtract 24 from that to represent that 8 large bottles is $24 less than 12 small ones.
Then, proceed to solve the equation to get the answer of s=14. Because a small bottle is $14, you can check your work by substituting the 14 in replace of s. :
How to factor y^3 +2y^2 + 2y + 1
Answer:
Step-by-step explanation:
P(y) = y³ + 2y² + 2y + 1
P(-1) = (-1)³ + 2*(-1)² + 2*(-1) + 1
= -1 + 2 - 2 + 1
= 0
As, P(-1) = 0, (y + 1) is a factor.
Use synthetic division or remainder theorem.
-1 1 2 2 1
0 -1 -1 -1
1 1 1 0
quotient = y² + y + 1
y³ + 2y² + 2y + 1 = ( y + 1) (y² + y + 1)

Find the slope of the line that passes through:
(-4,7) and (-6, -4)
Answer:
[tex]\frac{11}{2}[/tex] or 5.5
Step-by-step explanation:
In order to find the slope of a line using two points on a graph, you must use
[tex]y_2-y_1/x_2-x_1[/tex]
Pluging in the points (-4,7) and (-6, -4) to the formula you will get:

Randy is thinking of a number. When he adds 7 to the number, multiplies the sum by 3, then subtracts 2, the result is 13. What is the original number?
A. 6
B. -2
C. 2
D. -6
Answer:
B. -2Step-by-step explanation:
let the number be x
=7+x
=3(7+x)
=3(7+x)-2
13=3(7+x)-2
solving for x we have
13=21+3x-2
21+3x-2-13=0
collect like terms we have
21-2-13+3x=0
6+3x=0
6=-3x
x=6/-3
x=-2

Answer:
q1 (1,-3)
r1 (3,3)
s1 (0,2)
t1 (-2,-1)
Step-by-step explanation:
When a shape is reflected, it must be reflected across a line
The vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:
[tex]\mathbf{q'(1,-3)}[/tex][tex]\mathbf{ r'(3,3)}[/tex][tex]\mathbf{ s'(0,2)}[/tex][tex]\mathbf{t'(-2,-1)}[/tex]The given parameters are:
[tex]\mathbf{q = (1,3)}[/tex]
[tex]\mathbf{r = (3,-3)}[/tex]
[tex]\mathbf{s = (0,-2)}[/tex]
[tex]\mathbf{s = (-2,1)}[/tex]
The transformation rule is given as:
[tex]\mathbf{rx-axis}[/tex]
The above rule means that the vertices are reflected over the x-axis
The rule of the transformation is:
[tex]\mathbf{(x,y) \to (x,-y)}[/tex]
So, we have:
[tex]\mathbf{q(1,3) \to q'(1,-3)}[/tex]
[tex]\mathbf{r(3,-3) \to r'(3,3)}[/tex]
[tex]\mathbf{s(0,-2) \to s'(0,2)}[/tex]
[tex]\mathbf{t(-2,1) \to t'(-2,-1)}[/tex]
Hence, the vertices for [tex]\mathbf{rx-axis}[/tex] of qrst are:
[tex]\mathbf{q'(1,-3)}[/tex]
[tex]\mathbf{ r'(3,3)}[/tex]
[tex]\mathbf{ s'(0,2)}[/tex]
[tex]\mathbf{t'(-2,-1)}[/tex]
