Answer:
1 speaker is $91.48
3 speakers = $91.48 × 3
= $274.44
1 tire is 9$2.55
5 tires = $92.55 × 5
= $462.75
8, 100 bills = $800
The cost for the 3 speakers and 5 tires = $274.44 + $462.75
= $737.19
Therefore, the change that Jason got was = $800 - $737.19
= $62.81

Answer:
d i think
Step-by-step explanation:
Among the senior class at a high school, 55% of Ms. Keating’s students plan on majoring in a branch of STEM, while 49% of Ms. Lewis’s students plan on majoring in a branch of STEM. Suppose Ms. Keating chooses 25 of her students at random and Ms. Lewis chooses 23 of her students at random. Since nKpK, nK (1 – pK) and nLpL, nL (1 – pL) are all greater than 10, the Normal condition is met. Let K = the proportion of Ms. Keating’s students from the sample who plan on majoring in a branch of STEM, and let L = the proportion of Ms. Lewis’s students from the sample who plan on majoring in a branch of STEM. What is the probability that the proportion of students who plan on majoring in a branch of STEM is greater for Ms. Keating?

Use the image to the right to answer the questions:
a. What theorems would/could you use to find x?
b. Find the value of x.
Thank you so much in advance! :)
Answer:
a. Linear pair theorem
b. x = 40
Step-by-step explanation:
a. You can use linear pair theorem. That is, two angles on a straight line are supplementary. They sum up to 180°
b. Thus:
x + (4x - 20) = 180°
x + 4x - 20 = 180
5x - 20 = 180
5x = 180 + 20
5x = 200
x = 200/5
x = 40
An artist mixes paint to make new colors. She uses 1/3 cup of red paint and
1/3 cup of yellow paint to make a batch of orange paint. If the artist has 2 cups of red paint available and 3 cups of yellow paint available, how many batches of orange paint can she make?
Answer:
6 batches
Step-by-step explanation:
1/3*6=2 cups of paint.
so they can make 6 batches and have 1 cup of yellow paint left

Someone help please, this is due in 10 minutes and I dont know the answer.
Answer:
Step-by-step explanation:
Rate of change = the difference in y/the difference in x.
20 - 6.50/4 - 1 = 13.5/3 = 4.5/1
24.5 - 20/5 - 4 = 4.5/1
33.5 - 24.5/7 - 5 = 9/2 = 4.5/1
The rate of change is 4.5.

2) The number of rose blooms in Betty's garden is 24 more than the number of blooms in May's garden. There
are at least 135 rose blooms in Betty's garden. How many blooms are possible in May’s garden?
Answer:
There are at least 111 rose blooms in May's Garden.
Step-by-step explanation:
135-24 is 111 and Betty doesn't have a maximum of rose blooms so that means she can have an infinite amount but it also means that may can't have less than 111.
Please let me know if I am incorrect

Help please thank uuuu
Answer:
B. x = 7; AB = 9, AC = 12
Step-by-step explanation:
12/4 = (x + 2)/(x - 4) (similar triangles theorem)
3 = (x + 2)/(x - 4)
Cross multiply
3(x - 4) = (x + 2)
3x - 12 = x + 2
Collect like terms
3x - x = 12 + 2
2x = 14
x = 14/2
x = 7
✔️AB = x + 2 = 7 + 2
AB = 9
✔️AC = (x + 2) + (x - 4) = (7 + 2) + (7 - 4)
AC = 9 + 3
AC = 12
A piece of wood is 3 1/2 feet long how many total inches long is it?
Answer:
42 inches
Step-by-step explanation:
1 foot is 12 inches
12 times 3=36
12 divided by 2=6
36+6=42
I need help on this question someone please help. x/4=-12 (this says x divided by 2 equals -8). Explain how you would solve for x and what you would get. I’m in 7th grade so can someone make it easy to read like at the explaining part thanks.
Work out the gradient of the line joining the points (2, 3) and (5,7)
Answer:
The gradient of the line joining the points [tex]P(x,y) = (2,3)[/tex] and [tex]Q(x,y) = (5,7)[/tex] is [tex]\frac{4}{3}[/tex].
Step-by-step explanation:
The gradient of the line joining two distinct point on a plane is represented by the slope of a secant line ([tex]m_{PQ}[/tex]), that is:
[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)
If we know that [tex]P(x,y) = (2,3)[/tex] and [tex]Q(x,y) = (5,7)[/tex], then the gradient of the line is:
[tex]m_{PQ} = \frac{7-3}{5-2}[/tex]
[tex]m_{PQ} = \frac{4}{3}[/tex]
The gradient of the line joining the points [tex]P(x,y) = (2,3)[/tex] and [tex]Q(x,y) = (5,7)[/tex] is [tex]\frac{4}{3}[/tex].

Find the value of x.
please explain how you got it :)
Answer:
x=65°
Step-by-step explanation:
Next to x would be 70. (180-110=70).
Since this is an equilateral triangle, the other angle is also 70.
180-70-70=40, so the third angle is 40.
Since this is a right angle, the other angle is 50 (90-40=50).
Since that is 50, and this is an equilateral triangle, the other two angles have to be the same.
180-50=130
130÷2=65
helppppp me please this twi
Answer:
4.) 7 : 4 = 36[g] : x [g]
7 * x [g] = 4 * 36 [g]
7 * x [g] = 144 [g]
x [g] = 144 [g] / 7
x [g] ≈ 20, 57 [g]

9514 1404 393
Answer:
(a) unique triangle(b) more than one triangle(c) no triangle possibleStep-by-step explanation:
1. Three sides lengths uniquely specify a triangle.
__
2. Three angle measures specify the shape of a triangle, but not its size. More than one triangle is possible with any given set of angle measures.
__
3. If the lengths do not satisfy 3 + 7 > 10, which they do not, then no triangle can be formed.
Gravel is being dumped from a conveyor belt at a rate of 15 ft3/hr and its coarseness is such that it forms a pile in the shape of an inverted right cone whose height is three times its base radius. How fast is the height of the pile increasing when the pile has a height of 10 ft
Answer:
0.43 ft/hr
Step-by-step explanation:
dv/dt = 15ft³/hr
Height = 10ft
We are required to get dh/dt
h = 3r
r = h/3
Formula for volume = 1/3πr²h
We put value of h
1/3π(h/3)²h
= 1/3π(h²/9)h
= 1/3πh³/9
= πh³/29
dv/dt = 1/27π.3h²dh/dt
= dv/dt = πh²/9dh/dt
Remember dv/dt = 15
When we put this in we get
dh/dt = 15x9/3.142x10²
= 135/314.2
= 0.43 ft³/hr
