a car uses 30 gallons of gasoline for a trip of 750 miles. How many gallons would be used on a trip of 450 miles

MariettaO [177]

Answer:

The answer is 18

Step-by-step explanation:

<h3><u>Given</u>;</h3>

A car uses 30 gallons of gasoline for a trip of 750 miles.

Gallons would be used on a trip of 450 miles.

Now, Gasoline used for one mile

30 ÷ 750 = 0.04

So,

0.04 × 450 = 18

Thus, 18 gallons would be used on a trip of 450 miles.

The length of the sides of four triangles are given. Determine which triangle is not a right triangle.a.5 mm, 12 mm, 13 mmb.20 m

gizmo_the_mogwai [7]

For a right triangle, the sum of the squares of two shorter side should be equal to the square of the third side. The calculations for each choices are shown below.

a. (5 mm)² + (12 mm)² = 169 mm² ; (13 mm)² = 169 mm² ; EQUAL
b. (20 mm)² + (48 mm)² = 2704 mm² ; (52 mm)² = 2704 mm² ; EQUAL
c. (6 mm)² + (8 mm)² = 100 mm² ; (10 mm)² = 100 mm² ; EQUAL
d. (11 mm)² + (24 mm)² = 697 mm² ; (26 mm)² = 676 mm² ; NOT EQUAL

Therefore, the answer is letter D.

*Reminder: If you have not filled out your graphic organizer to reflect the order of events in Part I of "The Monkey's

Andrew [12]

The two events that created the most tension in the story include:

Mrs. White suggests that her husband wishes for four hands for her.
Mr. White paid Sergeant-Major Morris a trifle for the paw.

<h3>What is tension?</h3>

It should be noted that tension in literature simply means the sense of something ominous in the literary work. It's a feeling that something is about to happen.

The Monkey's Paw is a horror short story by author W. W. Jacobs. In the story, three wishes are granted to the owner of The Monkey's Paw, but the wishes come with a price for interfering with fate.

It should be noted that Mrs. White suggesting that her husband wish for four hands for her created tension in the story as the readers were eager to know what happened in the story. Also, it should be noted Mr. White paying Sergeant-Major Morris a trifle for the paw created tension.

Hi there!

First, let's figure out how many feet are in the total amount of tape. This can be done by multiplying the amount of yards (4) and multiplying it by the amount of feet in a yard (3). This gives us 12 feet. Then, we need to subtract the amount of feet that are left (2). This gives us 10 feet.

ANSWER:
B - 10 feet

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

A random sample of 23 items is drawn from a population whose standard deviation is unknown. The sample mean is x⎯⎯ = 770 and the

zhannawk [14.2K]

Answer:

For α=0.01 and two-tailed test: t=2.8188

For α=0.025 and two-tailed test: t=2.4055

For α=0.05 and two-tailed test: t=2.0739

For α=0.10 and two-tailed test: t=1.7171

Step-by-step explanation:

In this problem, we have to estimate the value of the statistic "t" of a sample of size n=23 (22 degrees of freedom), in which the sample mean is M=770 and the sample standard deviation is s=25.

The estimated standard deviation is

$s_M=s/\sqrt{N}=25/\sqrt{23} =5.21$

The critical values of the statistic t depends on the significance level:

The degree of freedom is known: df=22.

For α=0.01 and two-tailed test: t=2.8188

For α=0.025 and two-tailed test: t=2.4055

For α=0.05 and two-tailed test: t=2.0739

For α=0.10 and two-tailed test: t=1.7171
