Answer:
181m - 38
Step-by-step explanation:
Hey there!
9(20m – 5) + (m + 7)
DISTRIBUTE
9(20m) + 9(–5) + m + 7
9(20m) + 9(–5)
9(20m) = 180m
9(–5) = -45
NEW EQUATION: 180 – 45 + m + 7
COMBINE your LIKE TERMS
(180m + m) + (–45 + 7)
“m” itself is understood as an invisible 1!
180m + m = 181m
–45 + 7 = –38
NEW EQUATION: 181m – 38
ANSWER: 181m – 38 ☑️
Good luck on your assignment and enjoy your day!

Two random samples of 25 people were asked how many 12-ounce cans of soda they consume each week. The first sample contained both males and females, aged 12-19. The second sample contained both males and females, aged 20-39. The results are shown in the table below. Using complete sentences, make one inference comparing the two groups, and explain your reasoning.
Answer:
One inference that can be made is that the age group of 12-19 consume more sodas than the age group of 20-39.
Step-by-step explanation: ok sooooo
The required individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19.
What is mathematical reasoning?Mathematical reasoning is the process of using logical thinking and mathematical concepts to solve problems, prove theorems, and develop mathematical models. It involves identifying patterns, making conjectures, and using deductive reasoning to arrive at logical conclusions based on given assumptions.
Based on the information given in the table, it can be inferred that individuals aged 20-39 consume more 12-ounce cans of soda per week than individuals aged 12-19. This inference can be made because the mean and median values of the second sample (aged 20-39) are higher than those of the first sample (aged 12-19). Specifically, the mean for the second sample is 8.6 cans of soda per week, while the mean for the first sample is 6.96 cans of soda per week. Similarly, the median for the second sample is 8 cans of soda per week, while the median for the first sample is 5 cans of soda per week.

B. the central angle is 90°.
C. the length of the arc it intercepts is the same as the length of the
radius.
O D. the radius has a length of 1
Answer:
C.) the length of the arc it intercepts is the same as the length of the radius

The length of the arc it intercepts is the same as the length of the
radius option (C) is correct.
What is a circle?It is defined as the combination of points that, and every point has an equal distance from a fixed point (called the center of a circle).
As we know, the relationship between arc length and the central angle:
s = rθ
[tex]\rm \theta = \dfrac{s}{r}[/tex]
Where 's' is the arc length and θ is the central angle, r is the radius of the circle.
If θ = 1 radian
Then,
s = r
Thus, the length of the arc it intercepts is the same as the length of the
radius option (C) is correct.

You go shopping and spend $264 on shirts and shorts. You purchase a total of 9 items. Each shirt costs $24 and each pair of shorts cost $32. How many of each did you buy?
Answer:
3 shirts, 6 shorts
Step-by-step explanation:
A total of $264 is spent during shopping on shirts and shorts
Each shirt costs $24
Each shorts cost $32
Therefore the quantity of shirts and shorts bought can be calculated as follows
24× 3= 72
32×6= 192
192+72= 264
Hence 3 shirts and 6 shorts were bought

Which are the intercepts of the equation y+2=4(x+1) ?
Answer:
*3rd option*
y intercept (0, 2)
x intercept (-1/2 , 0)
Step-by-step explanation:
First, rearrange the equation so y is on one side, the rest of the terms on the other.
y+2 = 4x + 4
y = 4x+2
The y intercept is 2 because x=0, y = 2
rearrange where x is on one side
4x = -y + 2
x = -1/4y - 1/2
The x intercept is -1/2 because when y=0, x=-1/2

On a coordinate plane, triangles P Q R and S T U are shown. Triangle P Q R has points (4, 4), (negative 2, 0), (negative 2, 4). Triangle S T U has points (2, negative 4), (negative 1, negative 2), (negative 1, negative 4). Complete the statements to verify that the triangles are similar. StartFraction Q R Over T U EndFraction = StartFraction P R Over S U EndFraction = StartFraction P Q Over S T EndFraction = StartFraction StartRoot 52 EndRoot Over StartRoot 13 EndRoot EndFraction = Therefore, △PQR ~ △STU by the theorem.
Answer:
The answer is below
Step-by-step explanation:
Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.
The distance between two points on the coordinate plane is given as:
[tex]Distance=\sqrt{(x_2-x_1}^2+(y_2-y_1)^2 \\\\Therefore\ in\ triangle\ PQR:\\\\|QR|=\sqrt{(-2-(-2))^2+(4-0)^2}=4\\\\|PQ|=\sqrt{(-2-4)^2+(0-4)^2}=\sqrt{52}=2\sqrt{13} \\\\|PR|=\sqrt{(-2-4)^2+(4-4)^2}=6[/tex]
In triangle STU:
[tex]|ST|=\sqrt{(-1-2)^2+(-2-(-4))^2}=\sqrt{13}\\\\|SU|=\sqrt{(-1-2)^2+(-4-(-4))^2} =3\\\\|TU|=\sqrt{(-1-(-1))^2+(-4-(-2))^2}=2[/tex]
|QR| / |TU| = 4/2 = 2
|PR| / |SU| = 6/3 = 2
|PQ| / |ST| = 2√13 / √13 = 2
Hence:
|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|
Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.
Similar triangles may or may not be congruent
Triangles PQR and STU are similar by SSS theorem.
The vertices of triangle PQR are given as:
[tex]P= (4, 4)[/tex]
[tex]Q= (-2, 0)[/tex]
[tex]R = (-2, 4)[/tex]
The vertices of triangle STU are given as:
[tex]S = (2, -4)[/tex]
[tex]T = (-1, -2)[/tex]
[tex]U =(-1, -4)[/tex]
Start by calculating the side lengths of the two triangles, using the following distance formula
[tex]d = \sqrt{(x_2 -x_1)^2 + (y_2 -y_1)^2}[/tex]
For triangle PQR, we have:
[tex]PQ = \sqrt{(4 --2)^2 + (4 -0)^2} = \sqrt{52}[/tex]
[tex]PR = \sqrt{(4 --2)^2 + (4 -4)^2} = 6[/tex]
[tex]QR = \sqrt{(-2 --2)^2 + (0 -4)^2} = 4[/tex]
For triangle STU, we have:
[tex]ST= \sqrt{(2 --1)^2 + (-4 --2)^2} = \sqrt{13}[/tex]
[tex]SU= \sqrt{(2 --1)^2 + (-4 --4)^2} = 3[/tex]
[tex]TU= \sqrt{(-1 --1)^2 + (-2 --4)^2} = 2[/tex]
Check if the side lengths of both triangles are similar, by dividing corresponding sides
[tex]k = \frac{PQ}{ST} = \frac{\sqrt{52}}{\sqrt{13}} = 2[/tex]
[tex]k = \frac{PR}{SU} = \frac{6}{3} = 2[/tex]
[tex]k = \frac{QR}{TU} = \frac{4}{2} = 2[/tex]
Because the scale factors of the side lengths are the same, then both triangles are similar by SSS theorem.
