Step-by-step explanation:

750t is basically 750 x t.

If t = 5 per say, this would be 750 x 5. It wouldn't take around 3,000 days to paint that fence. (probably)

We are trying to get the number of days, so lets focus at that.

If Olivia paints T planks per day , we are going to want to divide the number of planks (t), so we can get how many days it would take.

So lets set an example, t = 250, to simplify things.

750/250 = 3 days.

Therefore, 750/t is your correct answer instead.

Answer:

42.395

Step-by-step explanation:

We need to find the yards of ribbon that Elsa bought with her debit card.

The amount of ribbon that Elsa bought was 31 yards.

Initial amount which is present on the card is [tex]\$15[/tex]

Amount left after spending is [tex]\$12.83[/tex]

Amount spent on ribbon is [tex]15-12.3=\$2.17[/tex]

Converting to cents

[tex]2.17\times 100=217\ \text{cents}[/tex]

Cost of one yard of ribbon is [tex]7\ \text{cents}[/tex]

[tex]1\ \text{yd}=7\ \text{cents}\\\Rightarrow 1\ \text{cent}=\dfrac{1}{7}\ \text{yd}\\\Rightarrow 217\ \text{cents}=\dfrac{217}{7}=31\ \text{yd}[/tex]

The yards of ribbon that Elsa bought is [tex]31\ \text{yards}[/tex].

[tex] \frac{35}{27090} = 0.00129198966[/tex]

Answer:

QUESTION

35 divided by 27,090

ANSWER

[tex]0.00129198966[/tex]

Answer:

1) the volume of the entire cake is ≈ 392.5 cubic inches

2) the volume after 1/6 of it has been removed is ≈ 327.1 cubic inches

Step-by-step explanation:

1) Formula for a cylinder = π r^2 h

First, find the area of the base of the cake (doing π r^2)

A = π r^2

A = 3.14 · 5^2

A = 3.14 · 25

A ≈ 78.5 in^2

Next, multiply the area of the base by the height of the cake (multiplying π r^2 by h)

78.5 · 5 = 392.5 in^3

2) Just divide 392.5 by 6 and subtract what you get from 392.5.

392.5/6 ≈ 65.4

392.5 - 65.4 = 327.1 in^3

Answer:

1,440.34 ft OR 710.33 ft and 1690 ft

Step-by-step explanation:

1)

He starts at 2,150.67 feet and ends up in 1,440.34 feet.

If you're asking what number shows his change in elevation, it's obviously 1,440.34.

OR if they are asking for the difference, the answer is 710.33

2)

She starts ar 500 ft. When she gets off, it's 2,190 ft. If you subtract those 2 numbers, it should be 1690 ft.

[tex]\dfrac{a^{m}}{a^{n}}=a^{m-n}\\\\\\\dfrac{6^{-2}}{6^{4}}=a^{-2-4}=6^{-6}[/tex]

Answer:

Step-by-step explanation:

Let the other end point be (a,b)

Then the midpoint p(0,-1) is between the two end points (-1,0) and (a,b)

So

(0,-1) = ( (-1+a)/2 , (0+b)/2)

So we have

0 = (-1 +a) /2

0 = -1 + a

a =1

and

-1 = (0+b)/2

-2 = 0+b

b = -2

So the other end point is ( 1, -2)

Answer:

B = (A - C)/5

Step-by-step explanation:

Subtract both sides by C

A - C = 5B

Divide both sides by 5

B = (A - C)/5

Answer:

D(-2, 5).

Step-by-step explanation:

We are given that M is the midpoint of CD and that C = (10, -5) and M = (4, 0).

And we want to determine the coordinates of D.

Recall that the midpoint is given by:

[tex]\displaystyle M = \left(\frac{x_1 + x_2}{2} , \frac{y_1 + y_2}{2}\right)[/tex]

Let C(10, -5) be (x₁, y₁) and Point D be (x₂, y₂). The midpoint M is (4, 0). Hence:

[tex]\displaystyle (4, 0) = \left(\frac{10+x_2}{2} , \frac{-5+y_2}{2}\right)[/tex]

This yields two equations:

[tex]\displaystyle \frac{x_2 + 10}{2} = 4\text{ and } \frac{y_2 - 5}{2} = 0[/tex]

Solve for each:

[tex]\displaystyle \begin{aligned}x_2 + 10 &= 8 \\ x_2 &= -2 \end{aligned}[/tex]

And:

[tex]\displaystyle \begin{aligned} y_2 -5 &= 0 \\ y_2 &= 5\end{aligned}[/tex]

In conclusion, Point D = (-2, 5).

[tex]-4\frac{14}{15}[/tex]

Step-by-step explanation:

[tex]12\frac{2}{5} -17\frac{1}{3}[/tex]

Step 1. See if both mixed fractions have the same common denominator

Answer: No.

Explanation: The first fraction [tex](12\frac{2}{5})[/tex] has a denominator of 5 and the second fraction [tex](17\frac{1}{3})[/tex] has a denominator of 3.

Step 2. so now that we know they have different common denominator, find the LCM (Least Common Denominator) for both mixed fractions.

To do this, find their LCM' (Least Common Multiple).

Answer: 30.

Explanation:

Multiples of 5:

5: 5, 10, 15, 20, 25, 30, 35, 40, 45,...

Multiples of 3:

3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30,...

Their LCM' (Least Common Multiple) is 30.

Step 3. Convert each of the mixed fractions into a common denominator of 30.

Answer:     [tex]12\frac{2}{5} =12\frac{12}{30}[/tex]       [tex]17\frac{1}{3} =17\frac{10}{30}[/tex]

Explanation:

[tex]12\frac{2}{5} =12\frac{?}{30}[/tex]                 [tex]17\frac{1}{3} =17\frac{?}{30}[/tex]

To find their numerator, think about how 5 being multiplied by a number equivalent to 30 and 3 being multiplied by a number equivalent to 30 (as well).

Step 4. Use the two mixed fractions [tex](12\frac{12}{30} -17\frac{10}{30} )[/tex] to subtract

Answer:

Explanation:

[tex]12\frac{12}{30} -17\frac{10}{30} =[/tex]

Multiply denominator by whole number and add the numerator (Keep the denominators the same)

[tex]\frac{372}{30} -\frac{520}{30} =[/tex]

Subtract

[tex]-\frac{148}{30}=[/tex]

Simplify

[tex]-4\frac{14}{15}[/tex]

Final Answer

The difference between the two given mixed fractions is -4 14/15.

The given fractions are 12 2/5 and 17 1/3.

We need to find the difference of the given fraction.

Steps to subtract mixed fractions:

Step 1– Convert the mixed numbers into improper fractions.

Step 2– Find the common multiple of both denominators.

Step 3– Convert the fractions into common denominators.

Step 4– Solve the fractions.

Now, 12 2/5 can be written as 62/5 and 17 1/3 can be written as 52/3.

Difference=62/5 - 52/3

=186/15 - 260/15

=-74/15

=-4 14/15

Therefore, the difference between the two given mixed fractions is -4 14/15.
