Answer 1

Answer:

[tex]80\:\mathrm{km^2}[/tex]

Step-by-step explanation:

The area of a triangle can be given by [tex]A=\frac{1}{2}bh[/tex], where [tex]b[/tex] is the base of the triangle and [tex]h[/tex] is the height of the triangle.

As marked in the diagram, we are given the following:

Base of 10Height of 16

[tex]A=\frac{1}{2}bh=\frac{1}{2}\cdot 10\cdot 16=\boxed{80\:\mathrm{km^2}}[/tex]

Answer 2

Answer:

Hello! answer: 80 km

Step-by-step explanation:

To find area in triangles you can do

base × height ÷ 2 or base × height × 1/2

10 × 16 = 80 therefore the area is 80 km

The two dot plots below show the heights of some sixth graders and some seventh graders:

Two dot plots are shown one below the other. The title for the top dot plot is Sixth Graders and the title for the bottom plot is Seventh Graders. Below the line for each dot plot is written Height followed by inches in parentheses. There are markings from 52 to 57 on the top line and the bottom line at intervals of one. For the top line there are 2 dots above the first mark, 1 dot above the second mark, 1 dot above the third mark and 2 dots above the fourth mark. For the bottom line, there is 1 dot for the first mark, there are 3 dots above the second mark, 2 dots above the third mark.

The mean absolute deviation (MAD) for the first set of data is 1.2 and the MAD for the second set of data is 0.6.

Lisa went on a 52km hike. She divided the distance traveled evenly over 4 days.

How many meters did Lisa walk each day?

Answers

Answer:

52km divided by 4 = 13000m

Step-by-step explanation:

52 kilometers divided by 4 days is 13000 meters

4 days hike = 52km
1 day hike = 52/4
= 13km

1 km = 1,000m
13km = (13 x 1,000)
= 13,000m

Therefore Lisa walked 13,000 metres each day on her 4 day hike.

Hope this helps. :)

What is the total amount of Luis' pies that were left over?

Answers

Answer:

2 1/4 pies

Step-by-step explanation:

Find out how much pie was leftover from each pie:

Apple pie: 3/4, 4 - 3 = 1, 1/4

Blackberry: 1/2, 2 - 1 = 1, 1/2

Blueberry: 1/8, 8 - 1 = 7, 7/8

Cherry: 5/8, 8 - 5 = 3, 3/8

Peach: 3/4, 4 - 3 = 1, 1/4

There are 1/4, 1/2, 7/8, 3/8, and 1/4 pies left. The LCD if these numbers is 8, since 2*4 = 8, 4*2 = 8, and 8*1 = 8

1/4 = 2/8

1/2 = 4/8

7/8 = 7/8

3/8 = 3/8

1/4 = 2/8

2 + 4 + 7 + 3 + 2 = 18, so 18/8 pies, or 2 2/8, or 2 1/4

Answers

Answer:

d = -10/7 = -1 3/7

that is the answer for number 1.

For number 2. the answer is U = 13/4 = 3 1/4 = 3.25

step by step explanation

multiply both sides of the equation by 4 the least common multiple of 2,4

2 (5 x 2 + 1) -4 u = 9 then multiply 5 and 2 to get 10

2 (10 + 1) -4u =9

then add 10 and one to get 11

2 x 11 -4u =9

then multiply two and 11 to get 22

22 -4u = 9

then subtract 22 from both sides

subtract 22 - 9 to get -13

-4u = -13 then undo multiplication by dividing both sides divide both sides by 4-13 / -4 can be divided by positive 13/4

your answer is 13/4

Math:

Kim deposited $1,422 into a savings account. After 5 years, she had a total of $1,635.30 in her account. What is the interest rate?

Answers

Answer:

42.66%

Step-by-step explanation:

subtract the amount of money from after and before: 1,635.30 - 1,422 = 213.3

divide the amount of money gained by the years: 213.3/5 = 42.66

The person above is correct because if you take the original amount Kim had and subtract that from the amount currently there you get 213.30 and you take that and divide that by 5 because of the 5 years you get
42.66%

The surface area of a lantern shaped like a sphere is 452.16 square inches. What is the approximate volume of the lantern? Use 3.14 for π. Round your answer to the nearest hundredth.
A.150.72 in.3
B.452.16 in.3
C904.32 in.3
D.5,425.92 in.3

Answers

I think the answer is C 904.32 in.3

The approximate volume of the lantern is, V = 904.32 in³

How can the surface area of this sphere can be expressed ?

The concept here is using the surface area formula which is

A = Area = (4 π r² )  

V= Volume =( 4/3 π r³)

Then , We get;

A / V = 3 / r

Also, r = √A / 4π

Then we can substitute the values as

π = 3.14

r = √452.16 / 4×3.14

r = √36

r = 6

Hence, We get;

V = 4/3 πr³

V = 4/3 × 3.14 × 6³

V = 904.32 in³

What part of 1hr and 40 min is 25 min as a fraction?

Answers

Step-by-step explanation:

1 hour = 60 minutes

40 minutes out of an hour can be written as: 40/60

Fraction = 40/60

= (2 × 30) / (3 × 20)

Canceling out common factors of numerator and denominator, we get 2/3

Therefore, 40 minutes is 2/3 of an hour.

40 minutes is 2/3 of an hour
