8 1/2- 1 1/4? Show work

Answers

Answer 1

Answer:

[tex]7\frac{1}{4}[/tex]

Step-by-step explanation:

Change to improper fraction.

[tex]8\frac{1}{2}[/tex] ⇒ [tex]\frac{17}{2}[/tex]

[tex]1\frac{1}{4}[/tex] ⇒ [tex]\frac{5}{4}[/tex]

Find the least common denominator (LCD) of the two fractions. ⇒ 4

[tex]\frac{34}{4}[/tex] - [tex]\frac{5}{4}[/tex] = [tex]\frac{29}{4}[/tex]

Convert to a mixed number.

[tex]\frac{29}{4}[/tex] ⇒ [tex]7\frac{1}{4}[/tex]

Hence, [tex]8\frac{1}{2} - 1\frac{1}{4} = 7\frac{1}{4}[/tex]

Solution : 24 × [20 + (5 × 3)] ÷ 8

So, first let's solve the integers within perenthesis

24 × [20 + 15] ÷ 8

24 × 35 ÷ 8

Now, we need to divide it first after which we'll multiply the rest

A building is 240 feet tall. On a scale drawing, 1/4 inch = 10 feet. What is the height of the building in the scale drawing?

15 in
9 in
60 in
13 in

Help Pleaseee

Answers

Answer:

60 in = 240 ft

Step-by-step explanation:

240/4 = 60

15 x 4 = 60

9 x 4 = 36

60 x 4 = 240

13 x 4 = 52

6in

Think about it, 1/4 in equals to 10f.
Then 1 in would equal to 40feet.
That mean 6 in on the scale drawing would equal to 240 feet

2x10+5x1+6x(1/100)+4x(1/1000)

Answers

Answer:

25.064 or 25 8/125

Step-by-step explanation:

Remember PEMDAS

First do 1 ÷ 100 = 0.01, and 1 ÷ 1,000 = 0.001 .

Next multiply 2 and 10, 5 and 1, 6 and 0.01, and 4 and 0.001.

2 × 10 = 20

5 × 1 = 5

6 × 0.01 = 0.06

4 × 0.001 = 0.004

Now you have 20 + 5 + 0.06 + 0.004 =

20 + 5 = 25

25 + 0.06 = 25.06

25.06 + 0.004 = 25.064

Don't forget to check your answer. I checked already btw, and it's correct. :)

Which of the following is an even function?
Of(x) = (x - 1)2
O f(x) = 8x
Of(x) = x2 - x
O f(x) = 7

Answers

Answer:

f(x) = 7

Step-by-step explanation:

In an even function of x, all powers of x are even (2, 4, 6, etc.).  

In this case we have f(x) = 7, or 7x^0, which is an even function because the power (0) of x is even.

The number of counties in state A and the number of counties in state B are consecutive even integers whose sum is 94. If state A has more counties than state​ B, how many counties does each state​ have?

Answers

Answer:

Multiple answers.

Step-by-step explanation:

State A and State B together have 94 counties. State A has more counties than state B. So there can be multiple answers. Let us assume that you mean the two numbers are as close as possible.  A+B=94.  94/2 is 47, so the two numbers as close as possible are 46,48. The lowest you can get is 2 and 92.

For the pair of points, find the slope of the line that passes through both points.

If you get stuck, try plotting the points on graph paper and drawing the line through them with a ruler.
