Answers

Answer:

448

Step-by-step explanation:

I = Prt where I is the interest P is the principle r is the rate and t is the time

I = 400 * (.02) * 6

I = 48

The amount in the account is the interest plus the original amount

400 +48

448

Answer:

$ 448

Step-by-step explanation:

amount that Elena deposit (P) =$ 400

rate of interest (R)=2%

time (T)=6 years

formula to find interest is

Interest = PTR/100

=$400*6*2/100

=$4800/100

=$48

Total amout she receives after 6 years is

Amount = Interest + Principal

=$48 + $400

=$448

Answer:

Step-by-step explanation:

3 • 2 is used to find the length of the top measurement from the scale we're given, so you multiply 4 by 2 to get it in meters.

4 • 2 = 8.

You do the same to the right side of the bedroom, 3 • 3 = 9, so 4 • 3 = 12.

To find area, you multiply both sides (8 and 12).

8 • 12 = 96.

Answer:

Step 2: 47

Step 3: 84

Step 4: 114

Step-by-step explanation:

Step 2: The width is 21, and the length is 36.

Sum is addition, so it would be 21 + 36.

21 + 36 = 47

Step 3: 47 x 2 = 84

Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

Step 2:47
Step3: 84
Strp4: 114

The display at an aquarium has sea stars and eels in a ratio of 4:5. It also has 5/8 as many rockfish as sea stars. There are 40 more wolf eels than rockfish. How many Sea stars are there?

Answers

4.8 sea stars were there

64 sea stars in the aquarium.

What is Ratio?

Ratio is defined as a relationship between two quantities, it is expressed one divided by the other.

Ratio of see stars to eels = S : E = 4:5

E = 5/4(S)

Ratio of rockfish to sea strars = R : S = 5:8

R = 5/8(S)

E = R + 40

5/4(S) = 5/8(S) + 40

Multiply by 8 both the sides

10S = 5S + 320

5S = 320

S = 320/5

S = 64

Hence, 64 sea stars in the aquarium

(There are 18 chickens and 12 sheep in the field on Monday)

Answers

Answer:

18/12 lol

Step-by-step explanation:

The ratio 3:5 describes the ratio between the number of chickens to the total number of animals in the field on Monday.

What is ratio?

"It is the relation between two items and it shows the number of times one value is contained within the other." :

According to the given problem,

Number of chickens in the field = 18

Number of sheep in the field = 12

Total number of animals on the field,

= 18 + 12

= 30

The ratio between the number of chickens to the total number of animals on the field is,

=18/30

= 3/5

= 3:5

Hence, we can conclude that out of every 5 animals( chicken or sheep) in the field, there are 3 chickens.

Therefore, The ratio 3:5 describes the ratio between the number of chickens to the total number of animals in the field on Monday.

What is the area of the figure below?

Answers

answer: 88in^2
explanation: by separating the figure into easier pieces, simple triangles and rectangles, this problem becomes much easier.
by looking the overall length of the figure, we get 7, if you cut off the big rectangle in the middle from that seven, you end up with a diamond with a height of 10 and a length of 4. multiply those together to get the area of the points on either side.
10 x 4 = 40
now looking back at the rectangle, by adding up the heights, you get a height of 16. multiply this with the length of 3 and you get 48.
add the two and you get the total area.
40 + 48 = 88

Answer:

68 in

Step-by-step explanation:

Because the area of the squares is 3 x 3 = 9 and because there are two squares it is 18. The area of the central figure is 50 because i divided it into 4 triangles and 2 rectangles, each rectangle is 15 in and each triangle is 5 in so 15 x 2 = 30, 5 x 4 = 20 and 30 + 20 + 18 = 68

⸻⸻⸻⸻

To graph the second point, we need to understand the meaning of slope. The slope of a line can be remembered as 'rise over run'.The slope for the given equation is -3. This means we would have to go three units down and then one unit right from the y-intercept. Our new point would be (1,2).

Ahmad’s goal is to exercise for a mean of 45 minutes per day for one week. For the first six days of the week, he exercised 35, 40, 37, 42, 45, and 50 minutes. What is the number of minutes Ahmad must exercise on the 7th day to meet his goal for the week?

Answers

Answer:

41.5

Step-by-step explanation:

To find the mean, your supposed to add all the numbers you have and divide by how many numbers there are. In this question your numbers are 35, 40,37,42,45, and 50.

If you add them all up you get 249. Your next step is to divide by how many numbers there are. Since there are 6, your equation will now be 249 divided by 6. Your answer is now 41.5

So on the 7th day Ahmad exercised for 41.5 minutes. If you need to round then maybe 41 minutes.

Answer:

41.5

Step-by-step explanation:

On the 7th day Ahmad exercised for 41.5 minutes and if you want to put it simply its 41 minutes.

Answers

Answer:

Do unto one side of the equation, what you do to the other!

Step-by-step explanation:

An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.

Answer:

Keeping the equation balanced.

Step-by-step explanation:

You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

What is scatter plot?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

Here, we have,

We are given the scatter plot which shows the distance he has run and the time it took for each run.

We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?

One way to predict the time is by drawing a line that best fits the given data.

As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.

Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.
