What is the solution to the equation? a+5 2/3=9

Answers

Answer 1

Answer:

a=8+1/2

Step-by-step explanation:

We move all terms to the left:

(a+5)2/3-(9)=0

We multiply all the terms by the denominator

(a+5)2-9*3=0

We add all the numbers together, and all the variables

(a+5)2-27=0

We multiply parentheses

2a+10-27=0

We add all the numbers together, and all the variables

2a-17=0

We move all terms containing a to the left, all other terms to the right

2a=17

a=17/2

a=8+1/2

There’s 65 students total in sports, so you divide that by 100 to get your answer

Answer:

0.65

Step-by-step explanation:

sophomore + junior + senior = total number of students that play sports

20 + 20 + 25 = 65

65 ÷ 100 = 0.65

If each cube in the rectangular prism measures 1 cubic foot, what is the volume of the prism?


A.
8 cubic ft
B.
6 cubic ft
C.
11 cubic ft
D.
7 cubic ft

Answers

Answer:

6 cubic feet

Step-by-step explanation:

Since each cube represents 1 cubic foot

volume of the prism = number of cubes * volume of 1 cube

Given

number of cubes = 6

volume of 1 cube = 1cubic foot

Substitute

volume of the prism = 6 * 1

volume of the prism = 6 cubic feet

Cally wants to coat her driveway with a winter sealer. Her driveway is 18 feet long and shaped like a trapezoid. At the garage door, the driveway is 12 feet wide, then it widens to 20 feet at the street. How many square feet of sealer should Cally buy if she wants to apply two coats?

Answers

Answer:

Amount of Winter sealer for 2 coats[in square feet] = 576 square feet

Step-by-step explanation:

Given:

Length of drive way at garage door = 12 feet

Length of drive way at street = 20 feet

Length of total driveway = 18 feet

Find:

Amount of Winter sealer for 2 coats[in square feet]

Computation:

Amount of Winter sealer for 2 coats[in square feet] = 2[Area of trapezoid]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(Sum of parallel side)(Height)]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(12 + 20)(18)]

Amount of Winter sealer for 2 coats[in square feet] = 2[(1/2)(32)(18)]

Amount of Winter sealer for 2 coats[in square feet] = 32 x 18

Amount of Winter sealer for 2 coats[in square feet] = 576 square feet

Answers

Answer:

The common ratio is 1.2.

After 12 weeks the plant will be 4.46 meters long.

After one year the plant will be 6,552.32 meters long.

Step-by-step explanation:

Given that a marrow plants 0.5 m long and every week it grows by 20%, to find the value of the common ratio, calculate how long the plant is after 12 weeks and comment on the predicted length of the marrow after one year must be performed the following calculations:

0.50 x 1.2 ^ X = Y

Therefore, the common ratio is 1.2.

0.50 x 1.2 ^ 12 = Y

0.50 x 8.916 = Y

4.4580 = Y

Therefore, after 12 weeks the plant will be 4.46 meters long.

0.50 x 1.2 ^ 52 = Y

0.50 x 13,104.63 = Y

6,552.32 = Y

Therefore, after one year the plant will be 6,552.32 meters long.

What is the volume of a triangular prism whose base has an area of 38.2mm and heigh of the prism meausers 14mm?

Answers

Answer:

534.8

Step-by-step explanation:

Volume= area × height

= 38.2×14

= 534.8

Hence the volumer is 534.8

Answer:

534.8 mm

Step-by-step explanation:

The volume of a triangular prism is given by the relation :

Volume = Base area * height

Base area = 38.2 mm

Height = 14 mm

Hence, the Volume of triangular prism is :

V = 38.2mm² * 14mm

Volume = 534.8 mm

There are 220 ways to choose the paintings.

What is combination in mathematics?

"Combination  determines the number of possible arrangements in a collection of items where the order of the selection does not matter."

Formula for combination:

[tex]^{n}C_r=\frac{n!}{r!(n-r)!}[/tex]

For given example,

There are 12 paintings at an art show.

⇒ n = 12

Three of them are chosen randomly to display in the gallery window.

⇒ r = 3

So, using the formula for combination, the number of possible ways to choose the paintings would be,

[tex]\Rightarrow~ ^{n}C_r=\frac{n!}{r!(n-r)!}\\\\\Rightarrow~ ^{12}C_3=\frac{12!}{3!(12-3)!}\\\\\Rightarrow~ ^{12}C_3=\frac{12!}{3!\times 9!}\\\\\Rightarrow~^{12}C_3=220[/tex]

Therefore, there are 220 ways to choose the paintings.

Keiko and Eric each randomly surveyed people with cell phones. They recorded peoples’ ages (a years) and how many texts they send per day on average (t texts). For their respective data, they each drew a line of best-fit and determined its equation. They then compared equations and made inferences based only on the equations they calculated.

Answers

Answer:

subject?

Step-by-step explanation:

The inferences given can be concluded as (a) Agree, (b) Disagree, (c) Agree, (d) Disagree and (e) Disagree

What is an Equation?

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Given two equations made each by Keiko and Eric. They are,

Keiko : t = -1.63a + 92.14

Eric : t = -1.05a + 80.97

(a) As the value of a increases, the value of t decreases for both of the equations.

So the first statement is true.

(b) When a = 20 and 30, t = 59.54 and 43.24 in the equation of Keiko.

When a = 20 and 30, t = 59.97 and 49.47 in the equation of Eric.

On an average, Eric's equation gives more t.

So second statement is false.

(c) t = 92.14 and t = 80.97 when a = 0.

A person with 0 years old cannot end texts.

So y intercept does not have a relevant meaning.

So c is also true.

(d) -1.63 and -1.05 is the slope of the corresponding lines.

This means that for every 1 year increase in age, the number of text messages decreased by 1.63.

So this is false.

(e) Similarly, in case of Eric's equation, for very 1 year increase in age, the number of text messages decreased by 1.05.

This is also false.

Hence the inferences are either agreed or disagreed as explained.

Answer:  "greater than" for each of the 4 dropdown menus

======================================================

Explanation:

Divide each value in the table by 40

You should get:

Horse = 15/40 = 0.375Cow = 12/40 = 0.300Sheep = 14/40 = 0.350Pig = 19/40 = 0.475

Those decimal results are the experimental (ie empirical) probabilities. Theoretically, we should get 1/4 = 0.250 for each sticker type assuming each sticker is likely to be chosen. As you can see, each decimal value shown above is larger than the theoretical target of 0.250, so each answer is "greater than"

-----------

Here's another way to see why this is:

If we had 40 stickers total, and each animal has the same number of stickers, then we should have 40/4 = 10 stickers per animal type. But the table shows each frequency is above 10. So that must directly mean the empirical probability of picking any animal is greater than the theoretical probability.
