Answer:
Rico Spent $6.50 on each car.
Step-by-step explanation:If you divided 52 by 8 you get 6.5 in money it would be $6.50.
My answer is reasonable because my estimate ÷ 10 = $6.50
Answer:
The answers are: 6.5$ , divided by, and 5$
Step-by-step explanation:
In order to figure out the price of each toy car, we must divide 52/8 (the total price of the toy cars divided by the number of the cars) which equals to 6.5, meaning that each toy car costs 6.5$, since they all have the same price. We know that this is a reasonable price because say we were to estimate, meaning we'd take a guess without doing any calculations. Let's say we paid 50$ in total, which is easily divided by 10, if we were to round up both numbers, we'd get 5$ each. That's close to the true answer, making it reasonable to take such a guess.

determine the value of k if g(x) =4x+k is a tangent to f(x)= -x² +8x +20
Answer:
22
Step-by-step explanation:
222
The value of k in the given functions is; 24
What is the value of the function to the tangent?
We are given the functions;
g(x) = 4x + k as a tangent to f(x) = -x² +8x +20
For f(x) = -x² +8x +20
=> f'(x) = -2x + 8
Thus, slope of tangent at ( x , y) = -2x + 8
For g(x) = 4x + k
g'(x) = 4.
Thus, slope is 4
Therefore;
-2x + 8 = 4
-2x = -4
x = 2
Putting 2 for x in f(x) gives;
f(2) = -2² + 8(2) + 20
f(2) = 32
Thus, it is at (2 , 32)
Thus, (2 , 32) lies on g(x) = 4x + k
4(2) + k = 32
k = 32 - 8
k = 24

In a geometric sequence, the first term, a1, is equal to 3, and the fourth term, a4, is equal to 192. Which number represents the common ratio of the geometric sequence?
A. R=4
B. R=6
C. R=5
D. R=7
Plz help me! Before in 7mins.
9514 1404 393
Answer:
A. r = 4
Step-by-step explanation:
For common ratio r, the second term is ...
a2 = 3r
The next terms are ...
a3 = (a2)r = (3r)r = 3r²
a4 = (a3)r = (3r²)r = 3r³ = 192
Then the value of r is ...
r³ = 192/3 = 64
r = ∛64 = 4
The common ratio is r = 4.
The side of polygone have length 5,7,8,11&9, the perimeter of similar polygone is 75cm ,finde the length of the side of large polygon?
Answer:
The side lengths of the larger polygon are;
15 cm
20.625 cm
16.875 cm
9.375 cm
13.125 cm
Step-by-step explanation:
Firstly, we need to calculate the perimeter of the first polygon
Mathematically, we can get this by adding the side lengths together
We have this as;
5 + 7 + 8 + 11 + 9
= 40 cm
so we have the ratio of the lengths of both as;
75 cm/40 cm = 1.875
Now, we simply will multiply the lengths of the smaller polygon by 1.875
So we have the side lengths of the bigger polygon as;
1.875 * 5 = 9.375 cm
1.875 * 7 = 13.125 cm
1.875 * 8 = 15 cm
1.875 * 9 = 16.875 cm
1.875 * 11 = 20.625 cm
Describe the graph of the solution to the inequality 8x + 17 ≥ 137
Answer:
Simplifying
8x + 17 = 137
Reorder the terms:
17 + 8x = 137
Solving
17 + 8x = 137
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-17' to each side of the equation.
17 + -17 + 8x = 137 + -17
Combine like terms: 17 + -17 = 0
0 + 8x = 137 + -17
8x = 137 + -17
Combine like terms: 137 + -17 = 120
8x = 120
Divide each side by '8'.
x = 15
Simplifying
x = 15

Answer:
C
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
A
y = x + 1 ← has a y- intercept of 1
B
y = x - 1 ← has a y-intercept of - 1
C
y = 2x ← has a y- intercept of 0
D
y = 2x + 2 ← has a y- intercept of 2

Answer:
A
Step-by-step explanation:
a positive number times a negative number is equal to a negative number.
Because all negative numbers have a value less than 0 the inequality sign must face towards the 0
The inequality sign also must be a < or > not a ≤ or ≥ as no positive number times -11 will equal 0
so the answer would be x < 0

Find the median for the number of pencils.
Answer:
The median is 2
Step-by-step explanation:
Here, we want to get the median for the number of pencils
Firstly, we have to write out the numbers that form the box plot ; we have this as;
1,1,1,2,2,2,2,3,3,5
the median is sum of the 5th and 6th term divided by 2
The 5th term is 2
The 6th term is 2
So the median is;
(2 + 2)/2

Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative. Is Awad’s claim true or false? Explain your reasoning. If it is true, give an example to support his claim. If it is false, give a counterexample. Explain your reasoning..
Answer:
False
Step-by-step explanation:
False, because whenever you subtract a negative number, you always end up adding because two negatives make a positive. Lets say n is 4 and m is -3, 4-(-3) is going to turn into 4+3=7.
The Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.
What is the number system?A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.
Awad claims that when m is a negative integer and n is a positive integer, n - m is always negative.
The above claim is false because subtracting a negative integer always results in an addition because two negatives equal a positive.
For example, n is 6 and m is -2; 6 -(-2) will equal 6 + 2 = 8.
Hence, the Awad'claims that "when m is a negative integer and n is a positive integer, n - m is always negative". which is false.

What is the area of the shaded portion of the trapezoid in the figure, in terms of? The figure is not drawn to scale. All of the given measurements are in feet.
Answer:
(150-36π) ft^2
Step-by-step explanation:
we need to subtract the area of the circle from the area of the trapezoid to find the area of the shaded region.
area of circle=πr^2=π6^2=36π ft^2
area of trapezoid=(1/2)(a+b)h=(1/2)(12+13)12=150 ft^2
so, the area of trapezoid-area of circle=(150-36π) ft^2
