Answer:

20/9

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 80 and 36 is 4

Divide both the numerator and denominator by the GCD

80 ÷ 4

36 ÷ 4

Reduced fraction: 20/9

The height of a parallelogram is one-third its base. If the area of the parallelogram is 363 square inches, find its base and he

kipiarov [429]

Answer:

Height = 11 inches

Base = 33 inches

Step-by-step explanation:

In this question, we are asked to find the height and base of a parallelogram given the area of the parallelogram.

From the question, we are told that height is 1/3 of base. This means that base is 3 times the height

So if we represent the height with variable h, then the base is 3h

Mathematically the area of a parallelogram can be calculated by the formula

A = bh

Thus ,

363 = h * 3h

3h^2 = 363

divide through by 3

h^2 = 121

h = √121

h = 11 inches

since b = 3h , then b = 3 * 11 = 33 inches

(ii) The value V of a Porsche 718 Cayman that is tyears old can be modeled by

Elena L [17]

Answer:

Part A: What would be worth the car's worth in 2 years?

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

Step-by-step explanation:

Part A: What would be worth the car's worth in 2 years?

If V(t) = 420,000(0.965) ^t, therefore:

V(2) = 420,000(0.965)²

V(2) = 420,000 * 0.931225

V(2) = $ 391,114.50

Part B. In how many years will the car be worth $325,000?

If V(t) = 420,000(0.965) ^t, therefore:

325,000 = 420,000(0.965) ^t

325,000/420,000 = (0.965) ^t

0.7738 = 0.965^t

t = log 0.965(0.7738)

t = log 0.7738/log 0.965

t = 7.2 years (rounding to the next tenth) or approximately 7 years, 2 months and 12 days

0.2 years = 0.2 * 12 = 2.4 months

Can y'all help me with this. Thanks

jek_recluse [69]

Answer:

x = 64°

Step-by-step explanation:

180 makes up a trinagle. For this triangle, two sides aproaching 52 degrees. Meaning The other two angles will be the same. So, 180-52 to get 128. Then, because there is 2 needing an angle, then you divide 128 by 2 to get 64. 64° for each side thats not labeled. So the answer is, x=64°

use the graph of y=e^x to evaluate the expression e^0. round the solution to the nearest tenth if necessary

Wittaler [7]

In the attached picture you have the graph of $y=e^x$ . To evaluate the function at $x=0$ , you'll have to start from 0 on the x axis, and travel vertically until you meet the graph.

In this case, if you start from the origin, you have to go upwards one unit, until you meet the graph at (0,1).

So, if $x=0$ , $y=1$ .
