Step-by-step explanation:

Since we dealing with right triangles, we are going to use pythagoern theorem.

[tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex], where a and b are the two legs and c is the longest side or the slanted side( known as hypotunese.)

Let plug in the numbers

4^2+ b^2=9^2

16+b^2=81

b^2=65

sqr root of 65 is about 8.1

carol used 1 1/4 cups of flour in 2 muffins How many cups of flour are needed to make 12 similar muffin

Answers

Answer:

Step-by-step explanation:

Hey there! first, we divide 1 1/4 by 2 to get how much flour is used to make one muffin then we multiply 0.625by 12 because 1 1/4 ÷ 2 = 0.625

12 × 0.625 = 7.5

(7.5 is equivalent to 7 1/2)

Carol need 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

What is division?

The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.

Given:

Carol used 1[tex]\frac{1}{4}[/tex] cups of flour in 2 muffins.

That means, Carol used 5/4 cups of flour in 2 muffins.

Unit rate = 2x4/5

= 8/5

When we have 12 muffins,

then flour = 12x 5/8

= 60/8

= 7[tex]\frac{1}{2}[/tex] cups of flour.

Therefore, 7[tex]\frac{1}{2}[/tex] cups of flour for 12 muffins.

When Joseph moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 16 inches tall and Tree B was 37 inches tall. Each year thereafter, Tree A grew by 6 inches per year and Tree B grew by 3 inches per year. Let AA represent the height of Tree A tt years after being planted and let BB represent the height of Tree B tt years after being planted. Write an equation for each situation, in terms of t,t, and determine the interval of time, t,t, when Tree A is taller than Tree B.

Answers

The tree A is 3t taller than tree B.

Equation to represent tree A = 16 + 6t

Equation to represent Tree B= 37+ 7t

What is linear equation?

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given that : Tree A was 16 inches tall and Tree B was 37 inches tall.

Tree after 't' year

A= 16 + 6t

B = 37 + 7t

so,

A-B= 16 + 6t -(37+3t)

= 16 + 6t - 37 -3t

= 3t- 21

As tree A grew 2 times the tree B

then t'= 2t

A'- B'= 3t' -21

= 3(2t)-21

=6t -21

Thus, (A'- B')(A-B) = 6t-21- (3t-21)

= 6t-3t

= 3t

Hence the tree A is 3t taller than tree B

Equation to represent Tree A = 16 + 6t

Tree B= 37+ 7t

In a survey, 250 adults and children were asked whether they know how to swim. The survey data are shown in the relative frequency table. Can swim Cannot swim Adults Total 0.34 0.06 Children 0.48 0.12 Total What percentage of the people surveyed are adults? O A. 40% O B. 6% O C. 82% OD. 34%

Answers

Answer:

A 40%

Step-by-step explanation:

The percentage of the people surveyed that are adults is; A: 40%

How to interpret Frequency Table?

We are given;

Sample size of adults and children = 250

From the table, we see that;

Proportion of adults that can swim = 0.34

Proportion of adults that can't swim = 0.06

Thus;

Total proportion of Adults in the survey = 0.34 + 0.06

Total proportion of Adults in the survey = 0.40

Thus, percentage of people surveyed that are adults = 0.40 * 100% = 40%

Mya bought 6 slices of bread for $2.40 at her local grocery
store. How much would a package with 10 slices cost at the price
per slice?

Answers

Answer:

$4.00

Step-by-step explanation:

Find how much it would cost for one slice of bread by dividing 2.40 by 6 to get .4.

So .40 cents is for 1 slice of bread. If you got 10 slices of bread (multiply 10 by .4) you would get 4.

So it costs 4 dollars for 10 slices of bread.

Answer:

12 = 4

Step-by-step explanation:

Answer:

c ⋅ 4 = 12

Step-by-step explanation:

We know that on the right side of the hanger, it holds one square, and that square has a value of 12 units.

And on the left side, the hanger holds four pentagons, and each pentagon has a value of c.

So, we know that 4 pentagons equal one square, or 4c = 12.

So how can we make that into an equation?

To get 4c, we multiply c four times. It should look like this:

c ⋅ 4 = 4c

And, we know that 4c equals 12, so all we have to do is make an equation showing that. You should get:

c ⋅ 4 = 12

*If you are looking for the value of c, you should get 3 because 3 ⋅ 4 = 12, proving c = 3

The sum of all the encoded values is calculated.If the sum is greater than 100 , the method returns the original input string with "3" appended.Otherwise, the method returns the original input string with "X" appended.The following table shows some examples of calls to the generateID method.
