8 - 1 = 7

Final Answer: 8 and 1

Have an amazing day!
Answer 2

Answer:

8 and 1

Step-by-step explanation:

The sum means that the two numbers added together make up what they're asking. Difference means you're subtracting between the two. For our purposes, we can just look at each answer option and firstly see which one has a difference of 7.

8-1=7

4-5=-1

6-3=3

9-0=0

And just to double check, we try adding 8 and 1, which is 9! Yay! :P

If a window is to be 6 feet wide, how high should it be, to the nearest tenth of a foot, to be a golden rectangle

Answers

Answer:

3.7 feet

Step-by-step explanation:

A golden rectangle is a rectangle in which the length and the width are in the ratio 1 : 1.618

If the width of the rectangle is 6, the length = 6 / 1.618 = 3.708 ft

= 3.7 (to the nearest tenth)

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Answers

Answer:

20 degrees.

Step-by-step explanation:

The interior angles of a triangle add up to 180 degrees. One of them, bottom right, is already shown as 70 degrees. You can find the bottom left angle by subtracting 110, the supplementary angle, from 180 (the number of degrees in a straight line). The top angle, 2x, is equal to 40 degrees. (180-70-70 = 40). 40/2 = x, so x = 20 degrees.

Answers

Answer:

Option A: x = -10 is a solution.

Step-by-step explanation:

Here we have the inequality:

3*(x - 4) ≥ 5*x + 2

We can solve this for x as follows:

first, expand the left side:

3x - 12 ≥ 5x + 2

now, move all the terms with x to one side, and the other terms to the other side:

-12 - 2 ≥ 5x - 3x

-14 ≥ 2x

now let's divide both sides by 2

-14/2 ≥ 2x/2

-7 ≥ x

So the solutions are values smaller than -7

In the options, the only value smaller than -7 is the first one:

A: -10

Then the correct option is A.

One of Eric's steps is 18in long. How many steps would he take to walk 1 mile?

Answers

Answer:

3520 steps

Step-by-step explanation:

The first thing we must do is figure out how many inches are in a mile. (There are 63,360 inches in one mile). With that out of the way, we can now divide these inches by 18, since each of Eric's steps are 18 inches long, and we want to determine how many steps he would have to take. 63,360 divided by 18 is 3520. This means our answer is 3520 steps, and that is how many steps he must take to walk 1 mile. I hope you understood and please let me know if you still need help!

Answer: 3520 steps

Step-by-step explanation:

1 mile = 63360 inches1 step = 18 in

Use proportions and set x = number of steps in a mile:

[tex]\frac{1}{18 in}=\frac{X}{63360 in}[/tex]

18x = 63360

x = 63360 ÷ 18 = 3520 steps.

dividing both to get a : c

What is the standard form equation of the line shown below? Graph of a line going through negative 1, 5 and 2, 4

Answers

Answer:

y = -1/3x + 14/3

Step-by-step explanation:

We have the standard equation as;

y = mx + b

where m is the slope and b is the y-intercept

the given points are;

(-1,5) and (2,4)

So we plug x and y for each of the points

then we create two linear equations which we can solve simultaneously to get the values of m and b

From the points;

5 = -m + b•••••••(i)

4 = 2m + b

from i;

b = 5 + m

substitute this into equation ii

4 = 2m + 5 + m

4 = 3m + 5

4-5 = 3m

3m = -1

m = -1/3

Recall;

b = 5 + m

b = 5-1/3

b = 14/3

so we have the equation as;

y = -1/3x + 14/3

Multiply through by 3

3y = -x + 14

A man and his wife share a lottery prize of $1 500 000 in the ratio of 41:34. What is the difference between the man's share and his wife's share

Answers

Answer:

$140,000

Step-by-step explanation:

Value of lottery = $1,500,000

Man's ratio = 41

Wife's ratio = 34

Total ratio = 41 + 34 = 75

Man's share = Man's ratio / Total ratio * Value of lottery

= 41/75 * $1,500,000

= 0.5466666666666 * $1,500,000

= $820,000

Wife's share = wife's ratio / total ratio * Value of lottery

= 34/75 * $1,500,000

= 0.4533333333333 * $1,500,000

= $680,000

Difference between the man's share and his wife's share

= Man's share - wife's share

= $820,000 - $680,000

= $140,000

sin50° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )

x × sin50° = 12 ( divide both sides by sin50° )
