Answer:

Stain required to stain the ramp = 2 quarts

Step-by-step explanation:

Area of the wheelchair ramp to be stained = Surface area of the ramp - Area of the rectangular base

Surface area of the ramp = 2(area of the triangular base) + (perimeter of the base)(height)

Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height of the triangle})[/tex]

                                             = [tex]\frac{1}{2}(25)(\frac{25}{12})[/tex]

                                             = [tex]\frac{625}{24}[/tex] in²

Perimeter of the triangular base = [tex]25\frac{1}{12}+25+\frac{25}{12}[/tex]

                                                      = 25 + [tex]\frac{1}{12}[/tex] + 25 + [tex]\frac{25}{12}[/tex]

                                                      = 50 + [tex]\frac{26}{12}[/tex]

                                                      = 50 + [tex]2+\frac{2}{12}[/tex]

                                                      = [tex]52\frac{1}{6}[/tex] ft

Surface area of the ramp = [tex]\frac{625}{12}[/tex] + [tex](52\frac{2}{12})\times 5[/tex] - 25×5

                                          = [tex]\frac{625}{12}+\frac{3130}{12}-125[/tex]

                                          = [tex]\frac{3755}{12}-125[/tex]

                                          = 187.92 square feet

Since, 100 square feet area is covered by the stain = 1 quart

Therefore, 187.92 square feet will be covered by the stain = [tex]\frac{187.92}{100}[/tex]

= 1.8792

≈ 2 quarts

Answer:

She can get 10 pounds of steak and 10 pounds of chicken.

Step-by-step explanation:

As Jacie wants to have at least 20 pounds of meat, you can write the following  equation:

x+y=20, where

x refers to the pounds of steak

y refers to the pounds of chicken

Also, since the statement indicate that the steak is $8 per pound and chicken is $4 per pound and Jacie wants to spend at most 120 dollars on meat, you can write the following equation:

8x+4y=120

So, you have the following equations:

x+y=20 (1)

8x+4y=120 (2)

Now, you can solve for x in (1):

x=20-y (3)

Then, you can replace (3) in (2) and solve for y:

8(20-y)+4y=120

160-8y+4y=120

160-120=8y-4y

40=4y

y=40/4

y=10

Finally, you can relace the value of y in (3) to find x:

x=20-y

x=20-10

x=10

According to this, the answer is that she can get 10 pounds of steak and 10 pounds of chicken.

Given:

The given expression is:

[tex]10^{-8}\times 10^{-6}[/tex]

To find:

The expression in the form of [tex]10^{-n}[/tex].

Solution:

We have,

[tex]10^{-8}\times 10^{-6}[/tex]

It can be written as

[tex]10^{-8}\times 10^{-6}=10^{-8+(-6)}[/tex]        [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]10^{-8}\times 10^{-6}=10^{-8-6}[/tex]

[tex]10^{-8}\times 10^{-6}=10^{-14}[/tex]

Therefore, the required value is [tex]10^{-14}[/tex].

Answer:

44°

Step-by-step explanation:

8x - 4 = 6x + 8 (This is because they are corresponding angles)

8x - 6x = 8 + 4

2x = 12

x = 12 ÷ 2

x = 6

6x + 8 = angle 1 (Vertically opposite angles are equal)

Substitute the value of x in the equation '6x +8' to get the size of the angle.

6 × 6 + 8

36 + 8 = 44°

Angle 1  =  44°

Answer:

(15,23)

Step-by-step explanation:

-4x+3y=9

5x-2y=29

Let's multiply the first equation by 2 and the second equation by 3, in order to have the same coefficient on y.

-8x+6y=18

15x-6y=87

Add these two equations together to eliminate y.

7x=105

x=15

Now, plug in x, to find y.

5(15)-2y=29

75-2y=29

-2y=-46

y=23

Answer:

The answer is B. [tex]3\frac{1}{3} ft.[/tex]

Step-by-step explanation:

It states that the figures in the pair are similar

When you multiply 5*8 it gives you 40 on the first angle

If the figures are similar then the other angle will equal 40.

So we need to find out which number that is multiplied by 12 that will give you 40.

If we multiply [tex]12*3\frac{1}{3}[/tex], it should  give you 40.

Convert The mixed number into a improper fraction:

3 1/3=3*3+1/3

=10/3

Convert the element into a fraction:

12/1*10/3

Factor the number:

3*4/1=10/3

Cross - cancel the common factor: 3

4/1*10/1

Apply the fraction rule:

4*10/1*1

Multiply the numbers: 4*10=40

=40/1*1

Multiply the numbers: 1*1=1

=40/1

Apply the Fraction rule:

=40

Answer:

3x + 2y = 38,  3a + 2b = 38

Step-by-step explanation:

An equation may be defined as a statement that shows two mathematical expressions to be equal. It is to equate one thing to another thing.

In the context, two different equations for the situations are :

i). Let the shirt be represented by x

   And the socks be represented by y

Therefore, according to the question,

   3x + 2y = 38

ii). Let the shirt be represented by a

   And the socks be represented by b

Therefore, according to the question,

   3a + 2b = 38

Answer:

0.894

Step-by-step explanation:

This would be the area under the standard normal curve to the right of z = -1.25.  There are various ways in which we can calculate this area.  I will use a TI-83Plus calculator, which features the necessary normalcdf( function:

normalcdf(-1.25, 1000) = 0.894

So:  the area under the standard normal curve to the right of z = -1.25 is 0.894.  This area also represents the desired probability.
