1. The total cost:

(3 * 65) + (2 * 70) + (1 * 55) -> cost of dresses + jeans + earrings

Total: 195 + 140 + 55 = 390.

2. Money leftover:

500 - 390 = $110.

13-14. yes n

15-16. not n

Step-by-step explanation:

Everything on this side is less than, < but everything on this side is greater.

Everything on this side could be equal or less, ≤ but everything on this side is

not.

I'm had a hard time with the number line, but imagine a line going through the periods and there being a dot where the yes ns end, and start.

Intervals has each point represent more than one number making the line shorter.

Of the 16,071 degrees in mathematics given by U.S colleges and universities in the most recent year, 73% were bachelor's degrees

Alenkasestr [34]

Answer:

The correct answer is 0.4559.

Step-by-step explanation:

Number of degrees in mathematics given by U.S colleges and universities in the most recent year = 16,071

73% were bachelor's degrees= 73% of 16071 = 11731

Women who earned the bachelor's degree = 48% of 11731 = 5630

21% were master's degrees= 21% of 16071 = 3374

Women who earned the masters's degree = 42% of 3374 = 1417

The rest degree were doctorates= 16071 - 11731 - 3374 = 966.

Women who earned the doctorates degree = 29% of 966 = 280

Total number of women who got mathematics degree = 280 + 1417 + 5630 = 7327.

We need to choose a mathematics degree at random and find the probability that it was awarded to a woman

Probability = $\frac{7327}{16071}$ = 0.4559

Which answer choice is equivalent to the expression 3x-1/2?

alex41 [277]

You can substitute a number in for x and compare the answer choices (not the most efficient way but it's how I would do it). Let's just say x = 5. Then the expression would equal 0.25819889. Substitute 5 in for x is the answer choices and see which one is the same.

A) simplified is 0.004 repeating

B) simplified is 0.25819889

C) simplified is 0.12

D) simplified is 1.341640786

We can see that B is the right answer

Graph the equation on the coordinate plane. y = 4x+4

Alla [95]

To graph the equation of the line, find the x-intercept and the y-intercept of the function

we have

$y=4x+4$

we know that

The x-intercept is the value of x when the value of y is equal to zero

The y-intercept is the value of y when the value of x is equal to zero

Step 1

Find the x-intercept

For $y=0$

$0=4x+4$

$4x=-4$

$x=-1$

the x-intercept is the point $(-1,0)$

Step 2

Find the y-intercept

For $x=0$

$y=4*0+4$

$y=4$

the y-intercept is the point $(0,4)$

Step 3

Graph the points and draw the line

see the attached figure

therefore

the answer in the attached figure

Help me plx can somewon help me

Tcecarenko [31]

Move the decimal so that there is one non-zero digit on the left of the decimal point. (The number of decimal spaces you move = exponent on 10) Since the decimal is moving to the left, we know the exponent is positive.

2 + 7 = 9

Answer: 9 * 10^16
