Yes, we can able to know the temperature difference from 6 AM to 6 PM.
We need to convert all the temperature into one unit.

6 AM - 10 AM ---> 5 F = -15 C
10 AM - 2 PM ---> 6 F = -14.44 C
2 PM - 6 PM ---> 0 C.

So the total increase is 15C

Oliva is a stockbrocker. She makes 4% of her sales in commission.Last week,she sold $7,200 worth of stocks.
belka [17]

A) Commission made last week is $ 288

B) Commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

<em><u>Solution:</u></em>

From given,

Commission rate = 4 %

Last week,she sold $7,200 worth of stocks

<em><u>A. ) How much commission did she make last week?</u></em>

Therefore,

Commission\ amount = 4 \% of\ 7200\\\\Commission\ amount = 4 \% \times 7200\\\\Commission\ amount = \frac{4}{100} \times 7200\\\\Commission\ amount = 4 \times 72\\\\Commission\ amount = 288

Thus commission made last week is $ 288

B)

Given that,

If she were to average that same commission each week

To find the commissions earned in a year, treating a year as having exactly 52 weeks

Therefore,

commissions\ earned\ in\ a\ year = 288 \times 52\\\\commissions\ earned\ in\ a\ year = 14976

Thus commissions earned in a year,treating a year as having exactly 52 weeks is $ 14976

The equation y= ax describes the graph of a line. If the value of a is positive,
ohaa [14]

Answer:

Step-by-step explanation:

If the value a is positive in the linear equation y = a x ( for example: y = 2 x ) then the line ( from the left to the right ) must go up and to the right. It also passes through the origin ( 0, 0 ).           For x = 1: y = 2 * 1 = 2, so that point is ( 1, 2 ),  x2 > x1,  and y2 > y1.Answer:A. goes up and to the right.

Zanzabum

9514 1404 393

Answer:

  49.3 feet

Step-by-step explanation:

Shadow lengths and object heights are considered to be proportional, so we have ...

  tree height/(tree shadow) = Andrew's height/(Andrew's shadow)

  height / (85 ft) = (5.8 ft)/(10 ft)

  height = (85 ft)(5.8/10) = 49.3 ft

The tree is 49.3 feet tall.

Which equation represents inverse variation between x and y?
postnew [5]

Inverse variation means

When the value of x increases the value of y decreases.

When the value of x decreases the value of y increases.

So for an inverse variation we have the expression

y=\frac{k}{x}

or

x=\frac{k}{y}

The expression which represents this condition is

x=-\frac{15z}{y}

Hence option b) or the second option is the right answer.

8x{[(7+4)x2] - [(11-7)x4]}
Anni [7]
PEMDAS
P - Parentheses (or other grouping symbols)
E - Exponents 
M - Multiplication
D - Division
A - Addition
S - Subtraction

8x[(7+4)x^2] - [(11-7)x^4]\\  \\ 8x[(11)x^2] - [(4)x^4] \\  \\ 8x[11x^2] - [4x^4] \\  \\ 88x^3 - 4x^4 \\  \\ -4x^4+88x^3

If you then want to go on to factor it, your answer would be -4x^3(x-22)
