Andre hopes to make at least enough money this week to buy a new pair of soccer cleats. Let `n` represent the number of magazine subscriptions Andre sells this week. Write an algebraic expression for the amount of money he makes this week.
Answer:
C = 25 + 3n
Step-by-step explanation:
Andre has a summer job selling magazine subscriptions.
We are told that:
Andy earns $25 per week plus $3 for every subscription he sells.
Let us represent
C = Total amount of money he makes this week
n = the number of magazine subscriptions Andre sells this week.
Hence, Our Algebraic expression =
C = $25 + $3 × n
C = 25 + 3n

Write the slope-intercept inequality for the graph below.
(-2,3) (1,-6)
Answer:
y<=-3x-3
Step-by-step explanation:
m=y2-y1/x2-x1
m=-6-3/1-2
m=-3
y-y1=m(x-x1)
y-3=-3(x-(-2))
y-3=-3x-6
y=-3x-6+3
y=-3x-3
we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x-3
Matt has 11 white buttons. He has 9 fewer brown buttons than white buttons. Matt has 17 more grey buttons than brown buttons. How many buttons does Matt have in all?
Answer: 32 buttons
Step-by-step explanation:
Matt has 11 white buttons.
Matt has 9 fewer brown buttons than white buttons. This means he has (11 -9) = 2 brown buttons
Matt has 17 more grey buttons than brown buttons. This means that he has (2 + 17) = 19 grey buttons.
The total number of buttons that Matt has will be;
= 11 white + 2 brown + 19 grey
= 32 buttons
What is her average from Macy scores
Answer: 85.2
Step-by-step explanation:
The answer is correct because, to find your grades your bassicaly just looking for the mean. To find the mean you have to take all the numbers and add them after you do that you have to divide how ever much numbers you added. So in this case we do 90 plus 76 plus 88 plus 80 plus 92. That equals 426, and since we added five numbers we divide the answer by 5 and that equals 85.2.

Answer:
1) C: 113 m
2) C: 572.3 m²
3) B: 61.2 cm²
4) A: $2.2
6) C: 756 yd³
8) D: 3402 mm²
9) A: 25x + 125 < 500
Step-by-step explanation:
1) Formula for circumference of circle is;
C = 2πr
radius; r = 18 m
C = 2π × 18
C ≈ 113 m
2) Formula for area of a circle is;
A = πr²
Here we have diameter; d = 27
Thus, radius; r = 27/2 = 13.5 m
A = π × 13.5²
A = 3.14 × 13.5²
A ≈ 572.3 m²
3) The diameter of the semicircle is parallel to the base of the rhombus. Thus, diameter; d = 7 cm
Thus, r = 7/2 = 3.5 cm
Area of semi circle = ½πr² = ½ × π × 3.5² = 19.2 cm²
Area of rhombus = base x height = 7 × 6 = 42 cm²
Total area of object = 42 + 19.2 = 61.2 cm²
4) Cost of banana per pound = $0.4 per pound
Amount of banana bought = 5.5 pound
Amount spent = 0.4 × 5.5 = $2.2
6) Volume of triangular prism is;
V = ½bhl
b = 12 yd
h = 7 yd
L = 18 yd
Thus;
V = ½ × 12 × 7 × 18
V = 756 yd³
8) Volume of cuboid at the base;
V1 = lbh = 25 × 9 × 9 = 2025 mm²
Volume of cuboid at top;
V2 = 9 × 9 × 9 = 729 mm²
Volume of triangular prism;
V3 = ½bhl = ½ × 9 × 9 × (25 - 9) = ½ × 81 × 16 = 648 mm²
Total volume = 2025 + 729 + 648 = 3402 mm²
9) Cost per class; $25 per class
Charge for the supplies = $125
He doesn't want to spend more than $500.
Thus;

The difference in the height of the two trees is 15 feet
How to determine if the design meets the slope constraints?The height of the zip line on both trees is given as:
Height 1 = 25 feet
Height 2 = 10 feet
Calculate the difference in both heights
ΔHeight = Height 1 - Height 2
This gives
ΔHeight = 25 - 10
ΔHeight = 15
The question cannot be solved further because the horizontal distance between the trees is not given.

solve for x. round your answer to the nearest tenth if necassary.
Answer:
32.9 degrees
Step-by-step explanation:
cos (x) = 21/25
cos^1 (21/25)
= 32.856 --> round to 32.9
Answer:
32.9°
Step-by-step explanation:
You can see that relative to the angle that is x, we are given the side lengths that are adjacent and the hypotenuse. The trig function associated with this is cosine, and we get:
cos(x) = adj / hyp --> 21 / 25
To find x as the angle, we use the function arccosine,
x = arccosine(21/25)
x = 32.85988038°
And this rounds up to 32.9°
Marco walked 27/100 kilometers to the park.Then he walked 1/10 kilometer to the library. What fraction of a kilometer did he walk in all?
Answer: 37/100
Step-by-step explanation:
The fraction of a kilometer that he walked in all would be the sum of 27/100 and 1/10.
To add them, first find the lowest common multiple of both denominators. This number is 100 so will be the denominator.
Divide 100 by each denominator and multiply it by the numerator:
= (27 + 10) / 100
= 37/100
Note: 100/10 = 10
= 10 * 1 = 10 which is the second numerator.

Find the surface Area?
Answer:
[tex]150 km^{2}[/tex]
Step-by-step explanation:
Use the surface area equation of cylinder: [tex]A = 2\pi rh + 2\pi r^{2}[/tex]
The diameter is 6 km but you need the radius for the formula, so you divide the diameter by 2.
6÷2 = 3 --> r = 3
You already know h, aka the height.
Plug everything into the equation.
Answer:
150.72
Step-by-step explanation:
im usin 3.14 as pi btw
the term net means like imagine you unfold the shape like the walls of the shape are paper. its now a 2d net, which includes a rectangle and two circles.
so, surface area of a circle is pi r^2 so 3.14 * 3 * 3 = 28.26
times two cause theres two circles; top and bottom :3
56.52 = 28.26 * 2
rentangle surface area = h*l
the height of the rectangle is 5 and the length is the circumference of the circle
circumference is 2*3.14*r, which in this problem, is 3
2*3.14*3 = 18.84
now, h*l is 18.84*5 = 94.2
94.2 + 56.52 = 150.72

Step-by-step explanation:
Answer: Both C and D are 76
Step-by-step explanation:
Because this is a isosceles triangle both C and D are the same. Subtract 28 from 180 and you get 152. So D and C combined equals to 152 so divide that by 2 an you get 76.
