Answer:
Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x +1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected.
The answer:
Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells
how do we know:
because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.
because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.
because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5
hope this helps!

Volume = length x width x height
This formula can be used to find the number of cubes as well as the volume.
Number of Cubes: 36
3 x 4 x 3 = 12 x 3 = 36
Volume of One Cube: 1/64 cm^3
1/4 x 1/4 x 1/4 = 1/64
Volume of the Solid: 9/16 cm^3
Length = 1/4 + 1/4 + 1/4 = 3/4
Width = 1/4 + 1/4 + 1/4 + 1/4 = 1
Height = 1/4 + 1/4 + 1/4 = 3/4
3/4 x 1 x 3/4 = 9/16

Apollo 16's mission lasted just over 1 week 4 days. How many hours are there 1 week 4 days?
Answer:
264 hours
Step-by-step explanation:
there are 7 days in a week + 4 is 11
11 x 24 (HOURS IN A DAY) = 264 hours
hope this helps
Answer:
264 hours
Step-by-step explanation:
1 week = 7 days
1 day = 24 hours
Therefore, 7 · 24 = the number of hours in a week.
24 · 7 = 168
There are 168 hours in a week.
1 day = 24 hours
4 days = ? hours
4 · 24 = the number of hours in 4 days
24 · 4 = 96
There are 96 hours in 4 days.
You add 168 and 96 hours to get the total number of hours.
168 + 96 = 264

Which is different?
A.) What is the distance around the circle?
B.) What is the circumference of the circle?
C.) What is $\pi$ times the radius?
D.) What is $\pi$ times the diameter?
Find “both” answers. Round to the nearest hundredth, if necessary.
The answer to the "same" questions is about (BLANK) inches.
The answer to the "different" question is about (BLANK) inches.
also i didnt mean to click it yet
Answer:
The different one is C, pi times the radius
Step-by-step explanation:
"Different" value is 18.85 and the "same" value is 37.70.
The distance around a circle, circumference and pi times the diameter all finds the same value, but pi time the radius is only half of those values
To the nearest tenth, what is the area of a circle whose diameter is 4.4 feet?
Use 3.14 for π.
Enter your answer in the box.
ft²
Answer:
15.21= 15.2 when rounded
Step-by-step explanation:
the formula for finding the area of a circle with the diameter is
A= 1/4 × π ×d^2
Answer:
15.21
Step-by-step explanation:
In order to find the area, you must find the radius first.
The diameter (4.4) divided by 2 = radius (2.2)
The area of a circle is pi times the radius squared ([tex]A = \pi r^{2}[/tex]).
In this situation, r, or radius =2.2.
[tex]A = \pi 2.2^{2}[/tex]
[tex]\pi[/tex][tex]2.2^{2}[/tex]= the area, 15.2053084434.
By rounding to the nearest hundredth, you get 15.21. The second number after the decimal is your hundredths place. If the number after the decimal is 4 or less, just remove all of the digits to the right. If it's five or more, like this case where it is 7, you add 1 to the hundredths place, then you remove all of the digits to the right.

This figure represents a prop for a play that will be built out of wood. The crew needs to build 4 of these props.
How much wood is needed to build all 4 props?
Enter your answer in the box.
ft²
Answer:
33600
Step-by-step explanation:
256 ft² wood will be needed for 4 props.
What is Surface Area?The area is the space occupied by a two-dimensional flat surface. It is expressed in square units. The surface area of a three-dimensional object is the area occupied by its outer surface.
According to the figure,
The lengths are
= (5ft +8ft +7ft +2ft +3ft +5ft) x 2 x 4
= 32 x 2 x 4
= 256 ft²
Thus, 256 ft² wood will be needed for 4 props.

Answer:
390m^2
Step-by-step explanation:
The Surface Area of a triangular prism is L(s1 + s2 + s3) + 2*base area
a = 5m
b = 12m
c = 13m
L = 11m
First, we need to find the base area...
base area = (a*b)/2
(5*12)/2 = 30 m^2
Next, find the surface area
A = 11(5 + 12 +13) + 2*30 = 390 m^2

A corner store sells 60-watt bulbs in packs of 4.
Write an equation that shows how the number of bulbs in stock, y, depends on the number of packages, x.
Answer: y = -4x + 60
Step-by-step explanation:
we can use a simple linear equation to write this problem:
y = mx + b
The slope is given to be the number of bulbs in each pack, which is 4.
now we have: y = 4x +b
The value of b is the y intercept, or the starting value, 60. From this value, 4x can be subtracted to show our remaining bulbs in stock:
y = 60 - 4x
Writing this in the form y = mx+b gives us the equation:
y = -4x + 60
Answer:
y = 4x
Step-by-step explanation:
A corner store sells 60-watt bulbs in pack of 4.
x = number of packs
y = number of bulbs
y = 4x
Check your answer using the problem:
60 = 4x
/4 /4
12 = x
This means that there are 12 bulbs in each pack.

{An angle measures 150° less than the measure of its supplementary angle. What is the measure of each angle?}
Answer:
165° & 15°
Step-by-step explanation:
Let the first angle be 'a'
second angle be (a-150°)
a+(a-150°) = 180°
2a=180°+150°
2a=330°
a=330/2
a=165°
first angle is 165°
second angle is 165-150=15°
