Answer:

110 cubic inches.

Step-by-step explanation:

Break the figure into 3D shapes you can find the volume of:

5x2x3 = 30

8x5x2 = 80

Add the 2volumes together:

30+80= 110

Hope this helps! Have a good day!

A positive number is 3 times another number.

Juli2301 [7.4K]

Answer:

The smaller number can be 8 or $\frac{1}{5}$ .

Step-by-step explanation:

Consider the provided information.

let the larger number is x and the smaller number is y

A positive number is 3 times another number.

$3y=x$

If we add 2 to the larger and 5 to the smaller, then one of them becomes 2 times the other.

Case I: If 2nd number is 2 times to the first number.

$x+2=2(y+5)$

Substitute the value of x.

$3y+2=2y+10$

$y=8$

Now substitute the value of y in $3y=x$

$3(8)=x$

$x=24$

Therefore, the smaller number is 8.

Case II: If 1st number is 2 times to the second number.

$2(x+2)=y+5$

Substitute the value of x.

$2(3y+2)=y+5$

$6y+4=y+5$

$5y=1$

$y=\frac{1}{5}$

Therefore, the smaller number is $\frac{1}{5}$ .

Which description corresponds to the relationship shown in the table?

Sladkaya [172]

Answer:

Step-by-step explanation:

7*5 = 35+15 = 50

10*70 = 70 +14 = 85

15*7 = 105 +15 = 120

20*7 = 140+15 = 155

B]8.50*5 = 42.5

C]10*5 = 50

10*10 = 100

D] = 8*5 = 40 +10 = 50

10*8 = 80+10 = 90

Which best describes the effect on the x-intercept of the graph of y=34x−3 if the slope is changed to −34

lesantik [10]

Answer:

The last option: The x-intercept becomes negative and the new line intersects the original line.

Step-by-step explanation:

Remember that when finding the x-intercept you set y to 0.

Let's compare the two equations when we solve for x:

0=34x-3 0=-34x-3

1. Add 3 to both sides of the equations

3=34x 3=-34x

2. Divide the coefficients

$\frac{3}{34}$ =x $\frac{3}{-34}$ =x

We know that the new slope does not remain the same as stated in the first and third options. In order for two lines to be parallel, the slopes must be exactly the same, so the second option is incorrect. Therefore, the last option is correct.

A square has a side that measures 5. 5 units. What is the area of a circle with a circumference that equals the perimeter of the

Eva8 [605]

The area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.

<h3>What is circumference and area of the circle?</h3>

Circumference of the circle is the length of its boundary. It can given as,

$P=2\pi r$

The area of the circle is the space occupied by it. It can be given as,

$A=\pi r^2$

Here (<em>r</em>) is the radius of the circle.

A square has a side that measures 5. 5 units. The perimeter of the square is the equal to the 4 times of its side. Thus its perimeter is,

$P=4\times5.5\\P=22\rm\; units$

The circumference of the circle is equal to the perimeter of the square. Thus the radius (<em>r</em>) of circle is,

$P=2\pi r\\22=2\times\pi r\\r\approx3.5\rm\; units$

The area of this circle is,

$A=\pi r^2\\A=3.14\times (3.5)^2\\A=38.465\\A\approx 38.47\rm\; units^2$

Hence the area of the circle whose circumference is equal to the perimeter of the square is 38.47 squared units.
