Andre has a summer job selling magazine subscriptions. He earns $25 per week plus $3 for every subscription he sells. 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

What is the surface area?
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

Answer:
they look like their curved at about 70? 65? and they would be the same
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.
Triangle GIH is similar to triangle KJL.select the angle whose tangent equals 6/8
Answer:
Step-by-step explanation:
The angle whose tangent equals 6/8 in triangle GIH is angle G.
What are similar figures?Two figures are said to be similar if they have the same shape and the ratio of their corresponding sides are in the same proportion.
Triangle GIH is similar to triangle KJL, hence the ratio of their corresponding sides are in the same proportion and their corresponding angles are congruent.
Hence:
JLcorresponds to IH and LK corresponds to GH. Hence:
tanG = tanK = 6/8
The angle whose tangent equals 6/8 in triangle GIH is angle G.

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;
25x + 125 < 500

Which function's graph has x-intercepts at x=−1 and x=3, and a vertex at point (1,−4)?
Answer:
Top right option: g(x) = (x+1)(x-3)
Step-by-step explanation:
x=-1 is the solution to x+1=0
x=3 is the solution to x-3=0
Therefore, your expression so far is (x+1)(x-3) or x²-2x-3.
Since the vertex must be (1,-4) we must check if x=1 satisfies the equation x=-b/2a:
x=-b/2a
1=-(-2)/2(1)
1=2/2
1=1
Both sides are equal to each other, so the final function is g(x) = (x+1)(x-3)
here is a graph of y=x^2-7x+10 for values of x from 0 to 7.
write down the roots of x^2 -7x +10=0.
ASAP please
Answer:
Roots of the function are x = 2, 5.
Step-by-step explanation:
Roots of a function are defined by the x-intercepts of the graph.
From the given graph in the question,
x-intercepts → x = 2, 5
Now confirm it by solving the equation algebraically,
x² - 7x + 10 = 0
x² - 5x - 2x + 10 = 0
x(x - 5) - 2(x - 5) = 0
(x - 5)(x - 2) = 0
x = 2, 5
Therefore, roots of the function are x = 2, 5.

Height 2 = 10 feet
Calculate the difference in both heights
ΔHeight = Height 1 - Height 2
This gives
ΔHeight = 25 - 10

How do I find the value of x. The answer is 25/7 I just need to show the work.
Answer:
Below.
Step-by-step explanation:
As the 2 sides are both cut in half by the horizontal line, 7x-1 = 1/2 * the base line, so:
2(7x - 1) = 48
14x - 2 = 48
14x = 50
x = 50/14
= 25/7.
Answer:
x = [tex]\frac{25}{7}[/tex]
Step-by-step explanation:
A segment joining the midpoints of 2 sides of a triangle is half the length of the third side, that is
7x - 1 = [tex]\frac{1}{2}[/tex] × 48 = 24 ( add 1 to both sides )
7x = 25 ( divide both sides by 7 )
x = [tex]\frac{25}{7}[/tex]

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.

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°
