Answer:
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
Step-by-step explanation:
Mai biked 5 1/4 miles today
So he biked, in miles:
[tex]5 + \frac{1}{4} = \frac{5*4 + 1}{4} = \frac{20+1}{4} = \frac{21}{4}[/tex]
Noah biked 2 1/2 miles.
So, in miles, he biked:
[tex]2 + \frac{1}{2} = \frac{2*2 + 1}{2} = \frac{4+1}{2} = \frac{5}{2}[/tex]
How many times the length of Noah’s bike ride was Mai’s bike ride?
We divide the Mai distance by Noah's distance. In a division of fractions, we multiply the numerator by the inverse of the denominator. So
[tex]\frac{\frac{21}{4}}{\frac{5}{2}} = \frac{21}{4} \times {2}{5} = \frac{21*1}{2*5} = \frac{21}{10} = 2.1[/tex]
The length of Mai's bike ride was 2.1 times the length of Noah's ride.
PLEASE HELP I WILL MAKE YOU BRAINLIEST!!!!! A rectangular prism has a volume of 198 cm³. A rectangular pyramid has the same height as the rectangular prism and a base that is congruent to the base of the rectangular prism.
What is the relationship between the volume of the rectangular prism and the rectangular pyramid?
(A) The volume of a rectangular pyramid is 2 times the volume of a rectangular prism. The volume of the rectangular pyramid is 396 cm3.
(B) The volume of a rectangular pyramid is 13 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.
(C) The volume of a rectangular pyramid is 3 times the volume of a rectangular prism. The volume of the rectangular pyramid is 594 cm3.
(D) The volume of a rectangular pyramid is 12 the volume of a rectangular prism. The volume of the rectangular pyramid is 99 cm3.
Answer:
(B) The volume of a rectangular pyramid is 1/3 the volume of a rectangular prism. The volume of the rectangular pyramid is 66 cm3.
Step-by-step explanation:
Volume of a rectangular prism:
The volume of a rectangular prism is given by:
[tex]V_R = A_{b}*h[/tex]
In which [tex]A_b[/tex] is the base area and h is the height.
Volume of a pyramid:
[tex]V_P = \frac{A_{b}*h}{3}[/tex]
Relation:
From this, given the same base and the same height, the volume of the pyramid will be a third of the rectangular prism.
A rectangular prism has a volume of 198 cm³
So the volume of the pyramid is 1/3 of this, that is, 198/3 = 66 cubic centimers.
The correct answer is given by option B.
Find the value of x and y
Answer: D. x=9√3; y=18
Step-by-step explanation:
This is a 30-60-90 special triangle, where we can use the rules to find the value of x and y. (For specific explanation, please look at the attachment below)
-----------------------------------------------------------------------------------------------------
X value
- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.
- Using the rules, the shortest side is x, then the second short side is x√3
- Substitute value in= x√3=(9)√3=9√3
Y value
- The shortest side of the triangle that corresponds with [x] is 9 units. This is because it is half of the larger triangle's side length.
- Using the rules, the shortest side is x, then the longest side is 2x
- Substitute value in= 2x=2(9)=18
Hope this helps!! :)

Imagine you measure the length of 15 cars, and then sum that length, in order to see how big a parking lot must be. You do this in two different ways. First, you use the same bad tape measure for each car so that your measurement is always 1 cm too long, or always too short, for all of the measurements. For your second attempt, you use a different bad tape measure for each car, so there is an uncertainty of plus or minus 1cm in each measurement. What is your estimate of the total error in the sum of all the car lengths in these two cases
Answer:
± 15 cm
Step-by-step explanation:
In the first case, since the measurement is 1 cm too long or too short, the error is ± 1 cm.
In the second case, the uncertainty or error is also ± 1 cm.
Now, since there are 15 cars, and there is an error of ± 1 cm in each measurement, by the error formula the total error in the sum of both cases is 15 × ±1 cm = ± 15 cm
So, the total error in both cases is ± 15 cm.

Because of a record corn harvest, excess corn is stored on the ground in a pile. The pile is shaped like a cone. The height of the pile is 25 ft, and the radius of the pile is 1.2 × 10 2 f t. Use the formula V = 1 3 π r 2 h to find the volume. Fill in the blanks provided below to represent your answer using 2 significant figures.
I need help please
Answer:
[tex]V=3141.59\ \text{feet}^3[/tex]
Step-by-step explanation:
Given that,
The height of the pile, h = 25 feet
The radius of the pile, [tex]r=1.2\times 10^2\ ft[/tex]
We need to find the volume of the pile of cone. The formula for the volume of a cone is given by :
[tex]V=\dfrac{1}{3}\pi r^2h\\\\V=\dfrac{1}{3}\pi \times (1.2\times 10^2)\times 25\\\\V=3141.59\ \text{feet}^3[/tex]
So, the required volume of the pile is [tex]3141.59\ \text{feet}^3[/tex].
A man could arrive on time for an appointment if he drove a car 40mph; however, since he left the house 15 minutes late, he drove the car 50 mph and arrive 3 min early how far from his house was his appointment
Answer:
60 miles
Step-by-step explanation:
Let us assume the distance between his home and place of appointment be x and t would be time taken at 40 mph
As we know that
Distance = speed × time
So,
x = 40t ............(1)
As he left the house 15 minutes late and also drove his car at 50 mph and arrive 3 minutes early
So,
15 minutes = 15 ÷ 60 = 0.25 hour
3 minutes = 3 ÷ 60 = 0.05 hour
Now the actual time taken is
= t - 0.25 - 0.05
= t - 0.30
x = 50(t - 0.30)
x = 50t - 15.............(2)
Now
40t = 50t - 15
10t = 26
t = 3 ÷ 2 hour
Now
x = 40 × 3 ÷ 2
= 60 miles
What is the solution to the equation? 14g = 154
A. 5
B. 11
C. 140
D. 2,156
Answer:
11
Step-by-step explanation:
14/14=154/14
g=11
Answer:
B. 11
Step-by-step explanation:
14g = 154
[given]
14g ÷ 14 = 154 ÷ 14
[division property of equality, divide both sides by 14 to cancel out the coefficient of 14 in 14g to get g]
g = 154 ÷ 14
[division property, how many times does 14 fit in 154?]
g = 11
________
11 is the solution because when 11 is substituted or plugged in for the variable g, it is multiplied by 14 to make 154.
g = 11 → 14g = 154
14(11) = 154
154 = 154 ✓

The expression 4g gives the number
of quarts in g gallons. How many
quarts are there in 4 gallons?
Answer: 16 quarts.
Step-by-step explanation:
1 quart = 1/4 gallon.
4 quarts = 1 gallon.
If you have 4 gallons, then you need to multiply 4 by 4, because every gallon is equal to 4 quarts.
4 x 4 = 16.
Therfore, there are 16 quarts in 4 gallons.
Write the equation for the function g(x) if the parent function f(x) is translated 3 spaces to the right and 2 spaces up.
Answer:

Step-by-step explanation:
If g(x) is just 3 spaces to the right and 2 spaces up from f(x), then g(x) = f(x–3) + 2
8 1/5-2 7/8 fractions
i removed my answer because it was wrong look at the other peoples answers
Answer: 213/40 or 5.325
Step-by-step explanation:
We can find common denominators for 8 1/5 and 2 7/8.
The Lowest Common Denominator for 8 1/5 and 2 7/8 is 40.
8 1/5 = 41/5 = 328/40.
2 7/8 = 23/8 = 115/40.
Now we can subtract.
328/40 - 115/40 = 213/40.
Therefore, the answer is 213/40 or 5 13/40.

A pail holds 6.3 liters of water. A bottle holds 3.5 liter less that water than the pail what is the volume of water in the bottle?
The correct answer is 2.8 liters
Explanation:
The volume of the water in the bottle can be calculated by subtracting 3.5 liters from the volume of water the pail can hold (6.3 liters) because the volume in the bottle is 3.5 liters less than the one in the pail. Below, you can find the process.
volume in the pail - 3.5 liters = volume in the bottle
6.3 liters - 3.5 liters = 2.8 liters
This means the volume of water in the bottle is 2.8 liters. Also, you can double-check this answer by adding the volume in the bottle and the 3.5 liters (2.8 + 3.5 = 6.3).

Answer:
[tex]y=- \frac{5}{4}x-4[/tex]
Step-by-step explanation:
1) if the A has coordinates (-4;1) and B - (-8;6), then it is possible to write the formula of the required line:
[tex]\frac{X-X_A}{X_A-X_B} =\frac{Y-Y_A}{Y_B-Y_A};[/tex]
