Maya is building a sandbox that is 48 inches wide. The length of the sandbox is four times the wldth of the sandbox. What is the perimeter of the sandbox?

Answers

Answer: 480 in.

Step-by-step explanation:

Given

The width of the sandbox is 48 in.

The length of the sandbox is four times the width

[tex]\therefore L=4\times 48=192\ in.[/tex]

Perimeter is the sum of the sides of the shape

The perimeter of the box is

[tex]P=2[48+192]=480\ in.[/tex]

Answer:

the perimeter of the sandbox is 480 inches

Step-by-step explanation:

The computation of the perimeter of the sandbox is shown below:

Since the width is 48 inches

And, the length would be four times the width i.e.

= 4 × 48

= 192 inches

Now the perimeter of the sandbox is

= 2( length + width)

= 2 (192 inches + 48 inches)

= 480 inches

Hence, the perimeter of the sandbox is 480 inches

On Monday, a local hamburger shop sold a combined total of 592 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Monday?

Answers

Answer:

148

Step-by-step explanation:

148 x 3 = 444

444 + 148 = 592

(っ◔◡◔)っ ♥ Hope It Helps ♥

148 hamburgers were sold on Monday.

Let x be the number of hamburgers sold.

Since the number of cheeseburgers sold was three times the number of hamburgers sold, the number of cheeseburgers sold can be represented as 3x.

The total number of hamburgers and cheeseburgers sold was 592. So, we can set up the equation:

x + 3x = 592

Combine like terms:

4x = 592

Now, solve for x by dividing both sides by 4:

x = 592 / 4

x = 148

Therefore, 148 hamburgers were sold on Monday.

I have to find the missing angles

Answers

Answer:

Angle 3 = 115°

Angle 4 = 22°

Angle 5 = 43°

Angle 6 = 115°

Step-by-step explanation:

These two triangles are congruent by SSS. It is given that two sides are congruent already, and by the reflexive property, they share a side and therefore have a third congruent side.

By CPCTC, all of their angles and sides are also congruent. And by the triangles angle sum theorem, side 3 and 6 must equal 115°

~~~

Have a nice day. Feel Free to ask questions. Spread the love.

Step-by-step explanation:

4 = 22⁰

5 = 43⁰

3 and 6 are same

kite total angles = 360⁰

so, to find 3 and 6, we need to subtract all angles we have and devide it with 2 because we need to find 2 angles...

360-22-22-43-43= 230

3 and 6 = 230 ÷ 2

= 115⁰

In a robotics competition, a robot must be built with a specific

height requirements, a robot must fit in the judge's plexi-glass box.
The box is a rectangular prism that has a surface area of 1 728 in”, a
width of 15 inches, and a length of 18 inches. The Mad Hatter robot
is 17.75 inches tall in its starting position. Does the Mad Hatter
meet the height requirement?

Answers

L = 18, W = 15 and H = ?
2*(15+18) + 2*(15H) + 2*(18H) = 540 + 30H + 36H
1,728 - 540 = 66H
1,188/66 = H = 18
so yes, it meets the height requirement 17.75 is less than 18

Which of the following is the correct order when multiplying two binomials?
Inner, first, last, outer
First, outer, inner, last
Outer, last, first, inner
Last, inner, outer, first
Please help.

Answers

Answer:

A technique for distributing two binomials. The letters FOIL stand for First, Outer, Inner, Last. First means multiply the terms which occur first in each binomial.

Step-by-step explanation:

The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.

What is binomial?

The binomial is a polynomial of two-term only. For example, x + 5 where x and 5 are two separate terms.

It is also known as the product. If the object n is given to m times then we just simply multiply them.

Let the two expressions are (a + b) and (c + d). Then the multiplication of the expressions will be given as,

⇒ (a + b) x (c + d)

⇒ a(c + d) + b(c + d)

⇒ ac + ad + bc + bd

The correct order when multiplying two binomials will be First, outer, inner, and last. Then the correct option is B.
