Answer:
1728
Step-by-step explanation:
6^3•2^6/ 2^3
6³.2⁶/2³
6³.2⁶⁻³
6³.2³
6x6x6.2x2x2
216.8
2126 x 8 = 1728
Answer:
Step-by-step explanation:
A = 2πr + πrl
A - 2πr = 2πr + πrl - 2πr (subtracting both sides by 2πr)
A - 2πr = πrl
(dividing both sides with πr)
(splitting LHS)
happy to help :)
Answer:
Step-by-step explanation:
First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal
Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.
However, we know two of three sides are equal, but the third should be also because of their similarity.
y+4 = 2y - 3
2y - y = 4 - 3
y = 4+3
y = 7
Therefore,
2y-3 = 2.7-3 = 14-3 = 11
Answer is 11 centimeters
Using pemdas you can solve it. Pemdas stands for parentheses, exponents, multiply, divide, add, and subtract. So you look at the problem and you look if there’s any parentheses which is not so then you move onto exponents which there is. Two to the third power is equal to 8. The problem then becomes 28+87/3•8
Then you look for multiplication. 3•8=24
It’s now 28+87/24
Next is division so you do 87/24 = 3.6
Now it is 28+3.6=31.6
The answer is 31.6
Answer:
c. 56.2 mph
Step-by-step explanation:
In most cars, the speedometer reading is proportional to tire rotation speed, so a larger diameter tire will go farther for the same number of rotations. That is, the distance traveled in a certain length of time is proportional to the tire circumference, which is proportional to the tire diameter.
The car with new tires will actually be going at the speed of ...
(26 in)/(24.5 in) × (53 mi/h) ≈ 56.245 mi/h ≈ 56.2 mph
