-7/10 + ? = -2 9/20 =
Answer:
-7/10 -13/10=-2
Step-by-step explanation:
?=x
-7/10+x=-2
x=-2+7/10
x=-20/10+7/10
x=-13/10
?=-13/10
So: -7/10-13/10=-2
Don is 6 feet tall. At a given time of day, he measures his shadow to be 10 feet long.
At the same time, he measures the shadow length of a nearby tree to be 38 feet. How
tall is the tree?
Round your answer to the nearest whole foot.
Answer:
Ok, so with this problem, you would start with the equation 6/10=x/38.
Then, cross multiply:
38(6)=10x
After, you would:
38 x 6 = 228
Then:
228/10
Lastly:
x=22.8m which when rounded equals 23 ft.
What is 6% of 90? Helpp

540/100=54
oliver drove the first 90 miles of his journey in 1.5 hours and the remaining 120 miles in 3 hours. what was the total average speed
90 miles + 120 miles = 210 total miles
1.5 hours + 3 hours = 4.5 total hours.
Average speed = total distance / total time
Average speed = 210 miles / 4.5 hours = 46 2/3 miles per hour
The total average speed for Oliver is 42 miles per hour
Given the following data:
Distance A = 90 milesDistance B = 120 milesTime A = 1.5 hoursTime B = 3 hoursTo find the total average speed:
First of all, we would determine the total distance and total speed:
[tex]Total \; distance = Distance\;A + Distance\;B\\\\Total \; distance = 90+120\\\\Total \; distance = 210\;miles[/tex]
[tex]Total \; time = Time\;A + Time\;B\\\\Total \; distance = 1.5+3\\\\Total \; distance = 4.5\;hours[/tex]
Mathematically, the average speed is given by the formula:
[tex]Average\;speed = \frac{Total\;distance}{Total\;time}[/tex]
Substituting the parameters into the formula, we have;
[tex]Average\;speed = \frac{210}{4.5}[/tex]
Average speed = 42 miles per hour.

The y-intercept is the value of the function when x=0. It is where the graph crosses the y-axis.
f(0) = a·b^0 = a·1 = a
Reading the y-intercept from the graph, we see ...
The y-intercept is 3. The a-value of the function is 3.
__
The point when x=1 is ...
f(1) = a·b^1 = 3b
Reading the value from the graph, we find the point to be (1, 6). This means ...
3b = 6
b = 2 . . . . . . . divide both sides by 3
The point when x=1 is (1, 6). The b-value of the function is 2.
The equation of the function is f(x) = 3·2^x.

Answer:
13/4 gallons per bucket or (as a mixed number) 3 and 1/4
Step-by-step explanation:
a gallon is made up of 4 quarts
so 13 qt/bucket* 1 gal/4 qts = 13/4 gal/bucket This label is because, since the quart labels are on opposite sides of the slash or division line this means we can cancel them which is why I multiplied it by 1 gal/4 gts instead of 4 qts/1 gal because even though both are true, one would cancel and one wouldn't.

Answer:

Step-by-step explanation:
13x-21=5x+75
8x=96
x=96/8=12
Answer:
x=12
Step-by-step explanation:
Since the 2 lines are parallel we can use the rules of transversals. These 2 angels are alternate side interior. This means that they are congruent and have the same measurement. Because they have the same measurement, we can set them equal to each other and solve for x.
First, set the expressions equal to each other13x-21 = 5x+75
Next, add 21 to both sides13x = 5x+96
Then, subtract 5x from both sides8x = 96
Finally, divide both sides by 8x=12
