42 because 3x3=6 and 6x7=42

Answer: x is 13

Step-by-step explanation:

90 - 67 is 23. Then you figure out what times 2 minus 3 is 23. Which would be 13. 13 times 2 is 26 minus 3 is 23. 67 + 23 is 90 ( right triangle)

Answer:

x=13

Step-by-step explanation:

The two angles are complementary, meaning that they both add up to 90°.

So, since we know that one of the angles is 67°, we can find the other one by subtracting 67 from 90.

90-67=23

So the equation is equal to 23.

2x-3=23

Add 3 to both sides.

2x=26

Divide both sides by 2.

x = 13

Answer:

I think it is x-2 and x=8

Answer:

C: 50

Step-by-step explanation:

The inner diamond has congruent sides

Half of the line segment on the left is 25.

The other half of the left line segment is also 25

Together, the left line segment is 50 units

The inner diamond has both 90 degree angles and 18 unit long sides

Thus, we know that both sides are congruent

Finally, the right side is the same length as the left side

The right side is 50 units long

Answer:

∠3 = 18°

∠4 = 144°

∠2 = 36°

∠1 = 72°

Step-by-step explanation:

From the concept of alternate interior angles,

∠3 = 18°

Since the diagonal divides the rectangle into 4 parts with 2 of the rectangles being similar.

Then, the triangle with ∠3 & ∠4 is an Isosceles triangle and as such;

∠4 = 180 - 2(∠3)

∠4 = 180 - 2(18)

∠4 = 180 - 36

∠4 = 144°

∠2 = 180 - ∠4 (because sum of angles on a straight line is 180°)

∠2 = 180 - 144

∠2 = 36°

Like it was done for angle ∠4 above;

∠1 = (180 - 36)/2

∠1 = 144/2

∠1 = 72°

Answer:

49[tex]\frac{1}{3}[/tex]

Step-by-step explanation:

I'm going to assume the number on the right side of the equation is 5.5, just to make things easier.

Now, to begin to solve this, first isolate the variable.

1/8y - 2/3 = 5 1/2

We do this by adding 2/3 to both sides.

1/8y = 5 1/2 + 2/3

Now, we just wipe off the coefficient that is stuck to the variable by dividing both sides by 1/8, which can be easier done by multiplying by the reciprocal (I converted the mixed number into an improper fraction before solving to facilitate the process).

y = (37/6) · 8

y = 296/6

y = 49 2/6 = 49 1/3

Answer:

0.83

Step-by-step explanation:

(a) z = (x - mean) / sd = (4000 - 3750) / 300 = 0.83

This corresponds to 0.7967 from the z-table, which represents how many last less than 4000 hours, so the answer is 1 - 0.7967 = 0.2033

(b) It will be P(x<4000) - P(x>3600) = 0.7967 - whatever the corresponding value is.

(c) same procedure as (b).

(d) 2% above corresponds to 0.02 which is a z-score of -2.05

-2.05 = (x - 3750) / 300

x = 3135

Step-by-step explanation:

The two numbers that sum to -6 and have a product of 12 are -3 ± √3i and -3 ± √3i respectively.

A numerical data is also referred to as a quantitative data and it can be defined as a data set that is primarily expressed in numbers (numerals) only. This ultimately implies that, a numerical data simply refers to a type of data set consisting of numbers (numerals) rather than words.

An expression can be defined as a mathematical equation which is used to show the relationship existing between two or more variables and numerical quantities.

In order to solve this word problem, we would assign variables to the unknown numbers and then translate the word problem into algebraic equation as follows:

Let the two unknown numbers be x and y.

Translating the word problem into an algebraic equation, we have;

Sum: x + y = -6     .....equation 1.

Product: xy = 12       ....equation 2.

From equation 1, we have:

x = -6 - y

Substituting equation 3 into equation 2, we have:

(-6 - y)y = 12

-6y - y² = 12

y² + 6y + 12 = 0

Solving the quadratic equation, we have:

y = -3 ± √3i

For the value of x, we have:

x = -6 - y

x = -6 - (-3 ± √3i)

x = -6 + 3 ± √3i

x = -3 ± √3i

A = 6 u²

Answer:

B will the correct answer.

Step-by-step explanation:

1/2 + 2/3 = 7/6 = 1 1/6

1/3 + 1/8 = 11/24

3/4 + 3/5 = 27/20 = 1 7/20

4/5 + 7/10 = 15/10 = 1 1/2

1 1/6 > 1

11/24 > 1

1 7/20 > 1

1 1/2 > 1

Answer:

29

Step-by-step explanation:

Answer:

If $1: 1500 items

If $20: 75 items

If those answers are not applicable, divide 1500 by whatever the cost of the shoes he is selling — that will be how many he will need to sell.

Step-by-step explanation:

So first lets set up an equation to figure this out.

So we know that he makes 20% based off of sales, so we’ll convert this to a decimal:

20% -> .20

Next we’ll make an equation to see what is needed to get at least $500.

0.20x + 200 = 500

Next we’ll have to get x by itself.

[tex]0.20x + 200 = 5000.20x = 300[/tex]

Next divide both sides:

[tex]X = 1500[/tex]

So if he is making sales of $1 he will need to sell 1500 items.

If he is selling them at $20, he will need to sell 75 items.

What ever the price value is for the items, divide that from 1500.
