The area of the composite shape is 136 square cm

<h3>Area of a composite function</h3>

The area of the composite function is expressed as;

Area = area of triangle + area of rectangle

Area of the composite shape = (1/2* 4 * 5) + (7*18)

Area of the composite shape = 10 + 126

Area of the composite shape = 136 square cm

Hence the area of the composite shape is 136 square cm

Perhaps that Margos spends X dollars on her paycheck , then I found my equation . 0.25 X + 0.125X + 24 = 60 ( 1/8 is equal to 0.125 ). After u solved this equation u will get $96 for the total amount of her paycheck.

Two girls had 45.00 to spend. one spent 6 dollars less than twice the other. solve

Varvara68 [4.7K]

Let, money spend by jane = x

Maggie spend = 2x-6

So, x+2x-6 = 45

3x= 51

x=17, 2x-6 = 28

So, jane spend $17 & Maggie spend $28

Complete Question

The complete question is shown on the first uploaded image

Answer:

The decision is to reject the null hypothesis at a significant level of significance $\alpha = 0.05$ There is sufficient evidence to conclude that at least one of the population mean is different from at least of the population

Step-by-step explanation:

From the question we are told that the claim is

The mean growth rates of all four species are equal.

The null hypothesis is

$H_o : \mu _1 = \mu_2 = \mu_3 = \mu_4$

Th alternative hypothesis is

$H_a: at \ least \ one \ of \ the \ means \ is \not\ equal$

From question the p-value is $p-value = 0.015$

And since the $p-value < \alpha$ so the null hypothesis will be rejected

To answer that question we need to use THE RULE OF THREE, this rule will help us solving linear relation problems.

Solution is:

The hour hand will turn (1/36)×π

The Table

Step minute hand hour hand

0-5 (1/6)×π (1/72)×π

10 (2/6)×π (1/36)×π

15 (3/6)×π = π/2 (1/24)×π

20 (4/6)×π = (2/3)×π (1/18)×π

25 (5/6)×π (5/72)×π

30 (6/6)×π = π (1/12)×π

35 (7/6)×π (7/72)×π

40 (8/6)×π (8/72)×π

45 (9/6)×π = (3/2)×π (3/24)×π

50 ( 10/6)×π ( 10/72)×π

55 (11/6)×π (11/72)×π

60 (12/6)×π = 2×π (12/72)×π = π/6

We know that each complete minute hand turn, is a 2×π angle turn, then a 5 minutes turn is (1/12) × 2×π = (π/6)
We will use that relationship to build the table and answer the question

If 2×π angle for a minute hand turn is equal to 1 hour, then

(2/6) angle for a minute hand turn is equal to "x" turn in the hour hand

So by Rule of Three, we proceed

2×π ( Of minute hand) ⇒ (1/6)×π (of hour hand)

(2/6)× π ( Of minute hand) ⇒ x

Solving for x

2×π × x = (2/6)× π × (1/6)×π

2× x = (2/36)×π

x = (1/36)×π

Now to build the table in 5 minutes steps:
