Answer: 7 marbles are green.
Step-by-step explanation:
Since we have 12 marbles in total, 12/12 = 1. Since the fractions have denominators of 12 as well, we can easily tell there are 3 yellow marbles (3/12) and there are 2 blue marbles (2/12).
Lastly, we need to find how many are green. We can subtract the yellow and blue marbles from the total of 12 marbles.
12 - (3 + 2)
12 - (5)
7 marbles are green.
Answer:
Seven marbles are green.
Step-by-step explanation:
you have a total of 12 marbles.
12-3 (yellow) = 9
9-2 (blue) = 7
3 (yellow) + 2 (blue) = 5
12 (total) - 5 (yellow and blue) = 7
A right triangle has one leg that is 7 centimeters. The hypotenuse is 25 centimeters. Find the length of the other leg.
Since this is a right triangle, we can use the Pythagorean Theorem to help us.
[tex](length-of-leg1)^2+(length-of-leg2)^2 = (length-of-hypotenuse)^2\\[/tex]
Known information:
one leg's length: 7 cmhypotenuse's length: 25cmNow let's plug the known information into the equation:
[tex]7^2 + (length-of-leg2)^2=25^2\\(length-of-leg2)^2 = 25^2-7^2\\\\(length-of-leg2)^2 = 576\\\\length-of-leg2=24[/tex]
Thus the length of the other leg is 24cm.

A bus company is replacing all the old seats in its buses with new ones. The company owns 12 buses and each bus has 21 seats. It costs $93.50 to
purchase each new seat, as well as an additional $31.20 to install each new seat. What is the total cost the company will pay?
Answer:
54,992.70$
Step-by-step explanation:
93.50 x 21 = 1963.5
31.20 x 21 = 655.2
1963.5 + 655.2 = 2618.7
2618.7 x 12 = 54,992.70$

Write the equation of a line PERPENDICULAR to the line y = 3x + 2 that passes through
the point (9,-2)
A. y=-1/3x +1
B. y=-1/3x-5
C. y=1/3x-5
D. y = 3x-29
Answer:
y=3x-7
Step-by-step explanation:
To find the equation of a perpendicular line, you first need to find the negative reciprocal of the slope given. The slope is -1/3, so the slope of the perpendicular line will be 3
Now we just need to find the y intercept using the point (3, 2) and you can plug the coordinates in and then solve for b. Let's see what that looks like.
y=3x+b
2=3*(3)+b
2=9+b
-7=b So now we know the y-intercept and slope. We just put them together now
y=3x-7

Find the area of this parallelogram
Answer:
101.46
Step-by-step explanation:
Area= Lenght x With
Soo you would do 11.4 x 8.9 and get 101.46cm!
The area of the parallelogram with a height of 7.1 cm will be 80.94 square cm.
What is the area of the parallelogram?Let H be the height and W be the width of the parallelogram. Then the area of the parallelogram will be given as,
Area of the parallelogram = H × W square units
From the graph, the width of the base of the parallelogram is 11.4 cm. And the height of the parallelogram is 7.1 cm.
The area of the parallelogram is given as,
A = 11.4 x 7.1
A = 80.94 square cm
The area of the parallelogram with a height of 7.1 cm will be 80.94 square cm.

Answer:
88 cm
Step-by-step explanation:
to find the circumference of a circle you can use the equation
d(pi)
d being diameter and pi in this case being 22/7
so you can directly multiply 28 and 22/7
28/1 * 22/7
you can cross cancel 28 and 7 making them 4 and 1 respectively
then you have 4/1 * 22/1
that is also 4 * 22
that is 88
Uncle Ron had 10 boxes of red pens and 15 boxes of blue pens. There were 47 red pens in each box. He sold 326 red pens and 471 blue pens. If he had 453 pens left, (a) how many blue pens did Uncle Ron have left? (b) how many blue pens were in each box?
please explain! and show your work! thanks
10 × 47 = 470
(a) 470 – 326 = 144
453 – 144 = 309
309 The number of blue pens Uncle Ron had left was
309 + 471 = 780
(b)
780 ÷ 15 = 52
Thus , 52 blue pens were in each box.

The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radius of the base?
Answer:
h = 4 cm
Step-by-step explanation:
The formula for volume of a cylinder is
V = πr²h where V is the volume, r is the radius, and h is the height.
We are given V = 64π, and r = 4, plug those in and solve for h
64π = π(4²)h
64π = 16πh
(64π)/(16π) = (16πh)/(16π) (divide both sides by 16π)
4 = (16π)/(16π)h
4 = h
Here, we are provided a right circular cylinder with :
Volume = 64 π cubic yards Height = 4 yards Radius = ?We know that :
[tex] \quad\hookrightarrow\quad{\pmb{ \mathfrak { Volume = \pi r^2 h }}}[/tex]
Therefore,
[tex] \implies\quad \sf{V = \pi r^2 h }[/tex]
[tex] \implies\quad \sf{64\pi = \pi r^2 \times 4 }[/tex]
[tex] \implies\quad \sf{ \pi r^2 \times 4 = 64\pi}[/tex]
[tex] \implies\quad \sf{r^2 =\dfrac{64\pi}{\pi \times 4} }[/tex]
[tex] \implies\quad \sf{ r^2 =\dfrac{\cancel{64}}{\cancel{4}}\times \cancel{\dfrac{\pi}{\pi}}}[/tex]
[tex] \implies\quad \sf{ r^2 = 16}[/tex]
[tex] \implies\quad \sf{r=\sqrt{16} }[/tex]

What is the value of x?
to
x = [?]°
o
Answer:
The value of x from the figure is 58 degrees
To get the value of x, we will use the formula:
The angle at the vertex = 1/2(difference of angles at the arc)
Angle at the vertex = 1/2(160 - x)
51 = 1/2(160 - x)
102 = 160 - x
x = 160 - 102
x = 58 degrees
Hence the value of x from the figure is 58 degrees
