Han has 10 cubes, each 5 inches on a side. Find the total volume of Han's cudes Express your answer as an expression using an exponent.
Answers
Answer:
2 * 5⁴
Step-by-step explanation:
Given :
Number of cubes = 10
Side length, a of each cube = 5
The volume of a cube = (side length)³
Hence, the volume of each of Han's cube = 5³
Therefore, the total volume will be :
Volume or cube * number of cubes
5³ * 10
10 = 2 * 5 = 2 * 5¹
5³ * 2 * 5¹
2 * 5^(3 +1)
2 * 5⁴

Circle T is shown. Angle Q S R intercepts arc Q R. Angle Q S R is 52 degrees. What is the measure of arc Q R? 26° 52° 104° 128°
Answers
Answer:
104 degrees'
Step-by-step explanation:
Find the diagram attached
According to the theorem;
Angle at the vertex is half the angle at its intercepted arc
Given
Angle at the vertex = 52 degrees
Angle at the intercepted arc = arc QR
Hence;
52 = 1/2 arcQR
Cross multiply
52 * 2 = arcQR
104 = arc QR
Swap
arc QR = 104 degrees'
Answer:
C)104

The dishwasher uses 32 gallons of water to wash 4 loads of dishes. How many gallons of water will the dishwater use to wash 10 loads of dishes?
Answers
Answer:
80 gallons
Step-by-step explanation:
32 divided by 4 to get the number of gallons it uses for 1 load of dishes which is 8. 8 multiplied by 10 = 80.
Answer 80 gallons
Step-by-step explanation:
32 divided by 4 equals 8, we have now found the rate of change. We then multiply 10 by 8 because for every load of dish it uses 8 gallons. So that equals 80 gallons.

5 and each group would be worth $2.10
Step-by-step explanation:
Sam has 24 quarters, 18 nickels, and 36 dimes. He wants to divide the coins into groups so that each group is worth the same amount of money. What is the greatest number of groups Sam can make using all the coins?
HURRY PLEASE
Convert this monies to dollar
Quarters - 24 x 0.25 = $6
Nickels = 18 x 0.05 = $0.9
Dimes = 36 x 0.1 = $3.6
sum of these amounts = $10.50
the greatest group is 5 and each group would be worth $2.10

1. (G. 12B) The radius of a circle is 5
inches. What is the length of a 70° arc?
(use 3.14 for 1)
Answers
Answer:
1.94 in
Step-by-step explanation:
The arc length formula is s = rФ. Here, r = 5 in and Ф = 70° But in this formula the central angle, Ф, must be in radians:
70°(1 rad)
-------------- = 0.389 rad
180°
Thus, the arc length here is s = (5 in)(0.889 rad) = 1.94 in
The dimensions of a box are x, 2x, and 3x. Each dimension is increased by 2. Calculate the volume of the box.
Answers
9514 1404 393
Answer:
6x^3 +22x^2 +24x +8
Step-by-step explanation:
The dimensions of the larger box are ...
(x+2), (2x+2), and (3x+2)
The volume is the product of these dimensions.
V = LWH
V = (x+2)(2x+2)(3x+2) = (x +2)(6x^2 +10x +4)
V = 6x^3 +22x^2 +24x +8
The volume of the box is 6x^3 +22x^2 +24x +8.

An initial population of 415
ducks increases at an annual
rate of 32%. Write an
exponential function to model
the duck population.
Answers
Answer:
The exponential function to model the duck population is:
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Step-by-step explanation:
In order to calculate the duck population you can use the formula to calculate future value:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
In this case, the present value is the initial population of 415 and the rate is 32%. You can replace these values on the formula and the exponential function to model the duck population would be:
f(n)=415*(1+0.32)^n
f(n)=415*(1.32)^n, where:
x is the duck population
n is the number of years
Dana gets paid $10 per hour plus a $10 bonus for the week. Tommy gets paid $9 per hour plus $13 bonus for the week. Set up a system of equations and tell how many hours they would need to work to earn the same amount.
A) 3 hours
B) 40 hours
C) 20 hours
D) 10 hours
Answers
Answer:
A) 3 hours
Step-by-step explanation:
x = per hour
y = total
Dana:
y = 10x + 10
Tommy:
y = 9x + 13
Combined (Solve for x):
y = 10x + 10
y = 9x + 13 (Multiply by -1)
y = 10x + 10
-y = -9x - 13
0 = x - 3
x = 3

Answers
Answer:
[tex]tan(\theta) = \frac{3}{4}[/tex]
Step-by-step explanation:
Remember the trigonometric ratios, keep in mind that the way the side is referred to is based on its position relative to the angle getting referenced. The side next to the referenced angle ([tex]\theta[/tex]) is called the adjacent side, the one opposite the angle is called the opposite side, and the side opposite the right angle of the triangle is called the hypotenuse.
[tex]sin (sine) = \frac{opposite}{hypotenuse}\\\\cos (cosine) = \frac{adjacent}{hypotenuse}\\\\tan(tangent) = \frac{opposite}{adjacent}[/tex]
In this problem, one is asked to find the value of ([tex]\theta[/tex]) with regards to a trigonometric function. One is given the opposite and adjacent sides, it would make the most sense to use the trigonometric function (tangent). Substitute the sides into their respective place, and simplify to find the value of the trigonometric function.
[tex]tan(\theta) =\frac{15}{20}\\\\\\tan(\theta)=\frac{3}{4}[/tex]
Uh whats the area of the figure??????
Answers
Answer:
42.5
Step-by-step explanation:
The figure shown is a trapezoid
The area of a trapezoid can be calculated using this formula
[tex]A=\frac{a+b}{2} h[/tex]
where a and b = bases and h = height
The trapezoid has the following dimensions
base 1 = 7 m
base 2 = 10 m
height = 5 m
Given this information we plug in the values into the formula
[tex]A =\frac{7+10}{2} 5\\7+10=17\\\frac{17}{2} =8.5\\8.5*5=42.5 \\A=42.5[/tex]
So we can conclude that the area of the trapezoid is 42.5 square units
