Answer:
$15 in 1 hour
Step-by-step explanation:
1 hour = 60 mins
60 mins divided by 8 = 7.5
7.5 x 2 = 15
Answer:
$15 dollars an hour
Step-by-step explanation:
There are 60 minutes an hour
So you will need to divide 60 by 8
60/8= 7.5
7.5*2=15
$15 dollars an hour
Ten baseballs weigh 1,417.4 grams. About how much does 1 baseball weigh? Round your answer to the nearest tenth of a gram. Round your answer to the nearest gram.. Which answer would you give if someone asked, "About how much does a baseball weigh?" Explain your choice.
Answer:
See explanation
Step-by-step explanation:
If all the ten balls weigh 1,417.4 grams
Then 1 ball weighs 1,417.4 grams/10 = 141.74
To the nearest tenth = 141.7
To the nearest gram= 142
If someone asks me the weight of one ball I will give the answer as 141.7 because it contains exactly the same number of decimal points as we have in the question.
The system of inequalities in the graph represents the change in an account, y, depending on the days delinquent, x. On a coordinate plane, 2 dashed straight lines are shown. The first line has a positive slope and goes through (negative 2, negative 2) and (0, 0). Everything to the right of the line is shaded. The second line has a negative slope and goes through (negative 2, 2) and (0, 0). Everything to the left of the line is shaded. Which symbol could be written in both circles in order to represent this system algebraically? y Circle x y Circle –x ≤ ≥

A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour? Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.? Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
Answer:
She rode 17.4 miles in 1 hour
Step-by-step explanation:
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?
The quotient is the average speed and this is calculated as:
Speed = Distance(miles)/Time(hours)
Where speed = quotient
Distance = Dividend
Time = Divisor
Speed = 60.9 miles/3.5 hours
= 17.4 miles/hour
Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
If :
3.5 hours = 60.9 miles
1 hour = x miles
Cross Multiply =
3.5x = 60.9 miles
x = 60.9/3.5
x = 17.4 miles
Hence, she rode 17.4 miles in 1 hour

Step-by-step explanation:
what is the slope and y intercept of y=3?
Answer:
m=0; y intercept=3
Step-by-step explanation:
The line is perfectly horizontal, which means that the slope is 0. Since it is horizontal, we can reason that the y intercept has to be 3.

What type of association is shown by the data in the scatter plot?
Answer Choices:
A. positive association
B. negative association
C. no association
D. trend association
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.How do you add integers with different signs?
Answer:
To add integers with different signs, keep the sign of the number with the largest absolute value and subtract the smallest absolute value from the largest.

Find V. 10 points plz.
Answer:
v = 60 yards
Step-by-step explanation:
In the similar triangles, their corresponding sides are proportional which means they have equal ratios
In triangles IHG and FHJ
∵ Δ IHG ≈ FHJ
∵ Side IH is corresponding to side FH
∵ Side HG is corresponding to side HJ
∵ Side IG is corresponding to side FJ
→ Their ratios are equal
∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]
∵ IH = 54 yards and FH = 72 yards
∵ IG = v and FJ = 80 yards
→ Substitute them in the first and last ratios above
∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]
→ By using cross multiplication
∴ v × 72 = 80 × 54
∴ 72v = 4320
→ Divide both sides by 72
∴ v = 60 yards
x^2 + 7x – 18 = 0
a
{–2, 9}
b
{–9, 2}
c
{2, 9}
d
{–2, –9}
Answer:
b)-9,2
Step-by-step explanation:
x^2+7x-18=0
x^2+9x-2x-18=0
x(x+9)-2(x+9)=0
(x+9)(x-2)=0
therefore
x=-9
x=2

How do I solve for the missing angle?!
And please include explanations on how you got the answer
Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75
