Three boxes are stacked one on top of the other. One box is 3 feet 7 inches tall, one is 3 feet 10 inches tall, and one is 4 feet 9 inches tall. How high is the stack? Write your answer in feet and inches. Use a number less than 12 for inches.

Answers

Answer 1

26 inches

I don't get the second part

Answer 2

You add up the height off all the stacked boxes together. easiest to start with the inches first, 7+10+9 which is 26 inches. simplify that to 2 feet 2 inches. Then add the feet, 3+3+4 which is 10. Add the two sums together. So, the answer would be 12 feet and 2 inches

Sandra runs at a rate of 8 miles in 45 minutes how does her unit rate compared to terrance's in Jessie's

Answers

Final answer:

Sandra's unit rate is 0.178 miles per minute, which is lower than Terrance's rate of 0.2 miles per minute and higher than Jessie's rate of 0.133 miles per minute.

Explanation:

To compare the unit rates of Sandra, Terrance, and Jessie, we need to determine how many miles they can run in one minute.

For Sandra, the unit rate is 8 miles in 45 minutes. To find the unit rate per minute, we divide 8 by 45, which is approximately 0.178 miles per minute.For Terrance, the unit rate is 6 miles in 30 minutes. Dividing 6 by 30 gives us a unit rate of 0.2 miles per minute.For Jessie, the unit rate is 2 miles in 15 minutes. Dividing 2 by 15 gives us a unit rate of 0.133 miles per minute.

Comparing the unit rates, Terrance has the highest rate at 0.2 miles per minute, followed by Sandra at 0.178 miles per minute, and Jessie at 0.133 miles per minute.

Complete question:

Sandra Runs at a rate of 8 miles in 45 minutes. how does her unit rate compare to Terrance and Jessie (Terrance 6 miles per half an hour jesse 2 miles every 15 minutes).

How many ants does it take to have the same mass as an elephant

Answers

First we observe that the mass of the ant is in grams, where the mass of the elephant is in metric tons. We cannot compare the two masses as is, so we first convert them into the same units. We can do this with ratios, using the conversion chart above to convert metric tons into kilograms and then kilograms into grams.

(8 metric tons)(1000 kg1 metric ton)(1000 grams1 kg)=8,000,000 grams=8×106 grams
Notice that both metric tons and kg appear once on both the top and the bottom, enabling them to be canceled out, leaving only grams. Also note that we could have converted .003 grams into metric tons, and though this would have given an answer with a large number of decimal places, we would end up with the same final result.

Now that both quantities are in grams, we want to find how many ants, n, are required to have the same mass as the elephant. As each ant has a mass of 4×10−3 grams, we multiply 4×10−3 by n to get the total mass of the ants
total mass of n ants=4×10−3n
and then we set this equal to the mass of the elephant:
4×10−3n=8×106
We find that n=2×109 ants.

Thus, it takes approximately 2×109 ants to have the same mass as an elephant.
Each ant is 10−1 cm long, and we have 2×109 ants total. If we put all these ants in a line (front to back), we can find the length of the line by multiplying the length of one ant by how many ants we have:
2×109×10−1 cm=2×108 cm
As is, this answer is difficult to illustrate because it is such a large number. To find two objects that are this distance apart, we first want to convert centimeters into more useful units. We do this by using ratios from the above chart, converting centimeters to meters and meters to kilometers.
(2×108 cm)(1 m102 cm)(1 km103 m)=2×103 km=2000 km
This amount is much easier to visualize, and it turns out that 2000 km is approximately the driving distance from San Francisco, California to Denver, Colorado.

Final answer:

To equal the mass of an elephant weighing 8 metric tons, it takes approximately 2 billion ants, each weighing 4×10^-3 grams.

Explanation:

The question asks how many ants would equal the mass of an elephant when the mass of an ant is approximately 4×10^-3 grams and the mass of an elephant is about 8 metric tons. First, we need to convert the mass of the ant into the same units as the elephant's mass. Since there are 1,000 grams in a kilogram and 1,000 kilograms in a metric ton, we can calculate the mass of the ant in metric tons as 4×10^-3 grams × (1 kilogram / 1,000 grams) × (1 metric ton / 1,000 kilograms), which simplifies to 4×10^-9 metric tons. To find the number of ants needed to equal the mass of an elephant, we divide the elephant's mass by the mass of one ant: 8 metric tons / 4×10^-9 metric tons per ant = 2×10^9 ants. Therefore, it takes approximately 2 billion ants to have the same mass as an 8 metric ton elephant.

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. A2 nd the third parameter is the slope of the line which represents the elevation of the line.

Given that a line passes through the points (−1, 7) and (2, 4). The equation of the line will be calculated by finding the slope of the line.

y = mx + c

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

m = ( 2 - ( -1 ) / ( 4 - 7)

m = ( 3 / -3 )

m = -1

y = mx + c

( 7 ) = ( -1 )( -1 ) + x

c = 6

The equation will be written as:-

y = mx + c

y = -x + 6

Therefore, the linear equation of the line will be y = -x + 6.

x = smaller, y = larger
larger (y) is (=) 12 more than (+) smaller (x)
y = 12 + x
x + y = 74
plug one equation into the other:
x + y = 74
x + (12+x) = 74
2x + 12 = 74
2x = 74-12 = 62
2x/2 = 62/2
x = 31
y = 12 + x = 12 + 31 = 43
So smaller number = 31
and larger number = 43

If a 40-m rope is cut into two pieces in the ratio 3:5 how long is each piece

Answers

Final answer:

The 40-m rope cut in a 3:5 ratio gives a 15 m piece and a 25 m piece. Doubling the rope length to 80 m with the same ratio yields a 30 m piece and a 50 m piece.

Explanation:

To find the length of each piece of a 40-m rope cut in the ratio 3:5, we need to work out the parts of the rope that each ratio value represents. First, we add the parts of the ratio together: 3 + 5 = 8 parts in total. Then, we find the length of each part by dividing the total length of the rope by the total number of parts: 40 m ÷ 8 = 5 m per part. Furthermore, to find the length of the smaller piece, we multiply the size of one part by 3, and for the longer piece, we multiply by 5.

Length of smaller piece = 3 parts × 5 m/part = 15 mLength of larger piece = 5 parts × 5 m/part = 25 m

Round each decimal to the nearest one then subtract $3.85-$2.17

Answers

Final answer:

To round $6.375 to the nearest one, it becomes $6.38. To subtract $3.85-$2.17, the result is $1.68.

Explanation:

To round decimal numbers to the nearest whole number, you will determine whether the decimal portion is closer to the previous or next whole number. If it is less than 0.5, you will round down, and if it is 0.5 or greater, you will round up. In this case, $6.375 is closer to $6.38, so you would round it up to $6.38.

To subtract decimals, you align the decimal points and subtract each place value from left to right. In this case, you would subtract $2.17 from $3.85:

$3.85

- $2.17

= $1.68

To round each decimal to the nearest one and then subtract $3.85 - $2.17, you start by rounding each number individually. $3.85 rounds to $4.00, and $2.17 rounds to $2.00. Once rounded, you then subtract the rounded numbers to find the total. So, it would be $4.00 - $2.00, which equals $2.00.

Find p+q, given that (q+4)(p+3)-(q+2)(p+1)=44.

Answers

We find that p+q = 17.

To find p+q, we need to solve the given equation step by step:

(q+4)(p+3) - (q+2)(p+1) = 44

Expanding both products, we get:

qp + 3q + 4p + 12 - qp - q - 2p - 2 = 44

We notice here that the 'qp' terms cancel each other out. Simplifying, we are left with:

2q + 2p + 10 = 44

Subtracting 10 from both sides gives:

2q + 2p = 34

Divide by 2:

q + p = 17

Therefore, p+q = 17.

CPCTC is often used to determine the similarities and congruence of two or more triangles.

Take for instance, the SSS congruence theorem means that the triangles are similar or congruent by Side-Side-Side.

Using CPCTC, it helps to know when the corresponding sides and/or the corresponding angles of the triangles that are being com pared are congruent.
