Answer:

Yeah, you're right. ( But please look at the explanation even though it's long. )

Step-by-step explanation:

<u>First. You need to understand each option:</u>

The first option shows that Jordan is taking $45 dollars and then adding $55 dollars to her bank account.

The second option shows that Harshika spent $45 on lunch and then used $20 more dollars.

The third option shows a plane that went up 600 feet then went down 200.

The fourth option shows that Jorge used $60 dollars to buy a sweater and then added $40 dollars.

<u>Then. Understand the question.</u>

The question is asking which option is telling you that the subject is taking money away or going down from an elevation.

<u>Finally. Eliminate, and solve with sense.</u>

Options 1 and 4 show taking away money and then adding money so both of those options are wrong.

Option 3 shows going up and then going down so that option is wrong.

Option 2 shows taking money only so it is the only correct answer.

She underestimated by 60 cents. To get this answer all you need to do is multiply 1 dollar times 12 which is $12 and then multiply $.30 by 12 and that gives you $3.60. Then you add the $12 to the $3.60 and that gives you $15.60 which is 60 cents over the estimation.

Complete the statements about these similar pyramids.

Goryan [66]

The ratio of the heights of the pyramid given at the end of the answer is of: 1:3.

The ratio of the surface areas of the pyramid given at the end of the answer is of: 1:9.

The ratio of the volumes of the pyramid given at the end of the answer is of: 1:27.

<h3>How to obtain the ratios?</h3>

The first step in obtaining the ratios is finding the ratio of the heights, which is given as follows:

5:15 = 1:3.

The heights are measured in units, while the surface area is measured in units squared, hence the ratio is squared, as follows:

(1:3)² = 1:9.

The volume is measured in cubic units, hence the ratio is cubed, as follows:

(1:3)³ = 1:27.

<h3>Missing Information</h3>

The pyramid is given at the end of the answer.

For different dimensions, the procedure of taking the ratio of the heights, then the surface area is squared and the volume is cubed remains.

Leto [7]

Answer:

X^2+6x+5=0

Step-by-step explanation:

Ax+By+C=0 is what you follow for getting the general form. In this case, you go from descending order and x^2 is the highest point/degree. Therefore, x^2+6x+5=0. Hope this helps!

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes,and 20 pages in 30 minutes. Is this a proportional relatio

maria [59]

Answer:

y = 2/3x

Step-by-step explanation:

<u>Reading rate is y pages per x minutes and proportional relationship formula is:</u>

y = kx

<u>The coefficient is:</u>

k = y/x

<u>Let's verify if the given numbers fit into the same relationship:</u>

12/18 = 2/3
8/12 = 2/3
20/30 = 2/3

We confirm all same and it means k = 2/3

<u>Required equation is:</u>

y = 2/3x

This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
