A new drill is used to dig a hole in the ground. At noon, the hole is 13.2 feet deep when the new drill is turned

on for the first time that day. At 2 p.m., the drill has dug the hole to be 42 1/4 feet deep. The new drill dug

1.5 times as much of the hole as the old drill would have in the same length of time.

(a) What expression represents the number of feet the new drill dug?

(b) How many feet would the old drill have dug in the same length of time? Show your work. Answer the
question in a complete sentence.

Answer:

90/91 ans

Step-by-step explanation:

=6×2+1/2 -7/8÷(5×16+11)/16

=12+1/2-7/8÷91/16

=13×8-7×2/16÷91/16

=90/91

Answer:

Computer is $866

Printer is $433

Step-by-step explanation:

We can form two equations given our variables:

Let's assume the computer=C and the Printer=P.

1) C+P=1299

2) 2P=C

Now we just plug in the 2nd equation into the 1st.

(2P+P)=1299

3P=1299

P=1299/3

P=433

Now that we know the value of the printer, we can subtract that from the total price:

1299-433=866

C=866

Answer:

the answer is 56.52 inches

Step-by-step explanation:

hope this helps :)

Answer:

56.52

Step-by-step explanation:

to find the circumference using radius, you multiply

r x pi x 2

9 x 2 x pi = 56.52

Dilating a trapezoid involves changing its size.

The measure of side OL is 8

The given parameters are:

[tex]\mathbf{O'L' = 6}[/tex]

[tex]\mathbf{k = \frac 34}[/tex]

Side length O'L' is calculated using:

[tex]\mathbf{O'L' = OL \times k}[/tex]

Make OL the subject

[tex]\mathbf{OL = \frac{O'L'}{k}}[/tex]

So, we have:

[tex]\mathbf{OL = \frac{6}{3/4}}[/tex]

[tex]\mathbf{OL = 8}[/tex]

Hence, the measure of side OL is 8

Answer:

(x - 2) • (x - 4) • (x - 8)

Step-by-step explanation:

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  +8  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 8 = 8  

Step-2 : Find two factors of  8  whose sum equals the coefficient of the middle term, which is   -6 .

     -8    +    -1    =    -9  

     -4    +    -2    =    -6    That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above,  -4  and  -2  

                    x2 - 4x - 2x - 8

Step-4 : Add up the first 2 terms, pulling out like factors :

                   x • (x-4)

             Add up the last 2 terms, pulling out common factors :

                   2 • (x-4)

Step-5 : Add up the four terms of step 4 :

                   (x-2)  •  (x-4)

            Which is the desired factorization

Answer:

2a. =  X = -5      2b. =  X = -4

Step-by-step explanation:

Hope this helps!

2a.   2 - 2x - 5 = 7

-2x = 7 + 5 - 2

-2x = 10

x = -5

2b.    -6 + x + 4 = -6

x = -6 - 4 + 6

x = -10 + 6

x = -4

Answer:

I think it would be by SSS

Step-by-step explanation:

SSS tells that if three sides of a triangle are congruent to three sides of another triangle, then the two triangles are congruent. The lines on the triangles show that they are congruent, so by looking at the sides, the triangles are congruent. If the sides are the same, then the angles are the same.

Answer:

1/3

Step-by-step explanation:

1) Simplify 3/4t to 3t/4

3t/4 = 1/4

2) Multiply both sides by 4

3t = 1/4 x 4

3) Cancel 4

3t = 1

4) Divide both sides by 3

t = 1/3

A = 728.85cm³

Answer:

A

Step-by-step explanation:

ok so we know the y is -5 (where the line crosses the y axis) so we can eliminate B & D. the answer is not C because the slope would be less steep

By looking at the formula that the rule is the coefficient of x times z to the power plus 2

so we can write the following geometric sequence

-x⁷,-2x¹²,-4x¹⁷,-8x²²,-16x²⁷.-32x⁵²....

Answer:

A=2 B=1

Step-by-step explanation:

B is distributive because you have to foil the x out of the parenthesis

A is  because when three or more numbers are added (or multiplied), the sum (or the product) is the same regardless of the grouping of the addends.
