Answer:

10 (8.06)

Step-by-step explanation:

H^2 = p^2 + B^2

H^2 = (7^2) + (4^2)

= $\sqrt{65\\$

= 0.8622

round off to 10

Answer:

The answer is 8.3

Step-by-step explanation:

(I'm not that good at explaining things so bear with me please. I checked on Khan Academy so it's right)

I split the box on the right diagonally and got the equation

$4^{2}$ + $2^{2}$ = $x^{2}$

=16 + 4 = $\sqrt{20}$

≈4.5

The new triangle will help solve what d is

$4.5^{2}$ + $7^{2}$ = $d^{2}$

=20.25 +49 = $\sqrt{69.25}$

≈8.3

Someone please help me with #15

harina [27]

Answer:

b. A year and a half

Step-by-step explanation:

First, we can find the total cost

$1512+263=1775$

Next, we can divide by 50 in order to find out how many months it will take for the panel to pay for itself.

$\frac{1775}{50} =35.5$ months

This is very close to 36 months, which is <u>A year and a half</u>.

I need help !!! can somebody please show me how to graph this.

MrRa [10]

Point s should be at 6,-2 and you have plotted at 6,2.
then, the line y=x goes from bottom left corner, through the origin to the top right corner. reflect your shape in this.

The length of a rectangle is 3 1/6 cm longer than the width. The perimeter of the rectangle is 15 1/3 cm. What are the width and

ahrayia [7]

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.

Step-by-step explanation:

Let,

Width of rectangle = w

Length of rectangle = $w+3\frac{1}{6}=w+\frac{19}{6}$

Perimeter of rectangle = $15\frac{1}{3}=\frac{46}{3}$ cm

Perimeter = 2(Length + Width)

$\frac{46}{3}=2(w+\frac{19}{6}+w)\\\\\frac{46}{3}=2(2w+\frac{19}{6})\\\\\frac{46}{3}=4w+\frac{19}{3}\\\\4w+\frac{19}{3}=\frac{46}{3}\\\\4w=\frac{46}{3}-\frac{19}{3}\\\\\ 4w=\frac{46-19}{3}\\\\4w=\frac{27}{3}\\\\4w=9$

Dividing both sides by 4

$\frac{4w}{4}=\frac{9}{4}\\\\w=\frac{9}{4}$

Width of rectangle = $\frac{9}{4}=2\frac{1}{4}\ cm$

$Length = w+\frac{19}{6}=\frac{9}{4}+\frac{19}{6}\\\\Length = \frac{27+38}{12}=\frac{65}{12}\\\\Length=5\frac{5}{12}\ cm$

The width of rectangle is $2\frac{1}{4}$ cm and length is $5\frac{5}{12}$ cm.

What is the area of the figure

topjm [15]

Answer:108 ins. squared

Step-by-step explanation:

So first you want to decide which way you want to divide the shape.

I am going to do it this way...

So the bottom is 16ins. and the top part is 10 ins.

So when you subtract 16-10 you get 6.

This means that the small portion sticking up is 6 ins. across.

According the left side the width with the small part is 8 ins.

So now we find the area of that half.

6 times 8 is 48ins.

Now we are going to get the other part.

The top says it is 10 ins.

The side says it is 6 ins.

Now we multiply 10 by 6 nd get 60 ins

We are almost finished, all we have to do is add 60 and 48.

Your answer is 108ins.squared.
