Answer:

[tex]4298.66mm^{2}[/tex], or [tex]1369mm^{2}[/tex][tex]\pi[/tex]

Step-by-step explanation:

Use the formula for area of a circle

A = [tex]\pi[/tex][tex]r^{2}[/tex]

the radius is half the diameter, so divide 74 by 2 then substitute it as r

A = [tex]\pi 37mm^{2}[/tex]

multiply 37 by 37

A = [tex]1369mm^{2} \pi[/tex]

multiple 1369 by pi(3.14)

[tex]1369mm^{2} \pi[/tex] or [tex]4298.66mm^{2}[/tex]

The performance rating increased by 2 points 2.04 would happen to the attitude rating.

The slope and the intercept values are given, the equation of a line can be found easily. So, it is also known as the slope and intercept form.

The standard form to represent the equation of a line is as follows:

Given

Managers at a company rate employees on performance and attitude and find that an employee's attitude depends on their performance.

They find a linear relationship and the line of best fit is y = 11. 7 + 1.02x.

The performance rating increased by 2 points what would happen to the attitude rating is;

[tex]\rm = 1. 02 x\\\\=1.02 \times 2\\\\= 2.04[/tex]

Hence, the performance rating increased by 2 points 2.04 would happen to the attitude rating.

Answer:

Step-by-step explanation:

Givens

d = 20 cm

r = d/2 = 20/2 = 10 cm

h = 2 cm

pi = 3.14

Formula

V = pi * r^2 * h

Solution

V = pi * r^2 * h

V = 3.14 * 10^2 * 2

V = 6.28 * 100

V = 628 cm^3

Answer:

Volume of the filling cabinet = 15ft^3

Step-by-step explanation:

volume = d * b * h

and the filling cabinet is

height = 5ft

width = 18 inch

depth = 2ft

we will first convert the width from inches to feet

where 1 ft -------- 12 inches

          (x) ft ---------18 inches

therefore by cross multiplying

 12 * (X) = 18 * 1

  12 (X) = 18

  X = 18 / 12

  X = 1.5 ft

so Volume = 2 * 1.5 * 5 = 15 cubic feet or 15ft^3

Answer:

8.4

Step-by-step explanation:

The diagonals of a rectangle are equal.

That means WY = XZ

16x+2 = 36x-6

Subtract 16x from each side.

16x -16x+2 = 36x-16x-6

2 = 20x -6

Add 6 to each side

2+6 = 20x-6+6

8 = 20x

Divide by 20

8/20 = 20x/20

2/5 =x

We want to find the length of the diagonal

WY = 16 ( 2/5) +2

Changing to decimal form

WY =16 * .4 +2

WY =6.4+2

     = 8.4

82.5+8(0.25x)=338.5

⇒-256+80.25x=0

Answer:

79

Step-by-step explanation:

cuz,
x equals the number of minutes so use the y slope formula

0.10(x)+the intercept = y
0.10(350)+the intercept = 84
35+the intercept = 84
the intercept = 49
so the equation is
0.10(x)+49 = y
or
1/10(x)+49 = y
1/10(300)+49=y
30+49=y
79=y
so the answer is 79 dollars

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

Explanation:

The 102 inscribed angle cuts off the arc that's composed of the 140 and 'a'.

Due to the inscribed angle theorem, we know that a+140 is exactly equal to twice that of 102.

This means,

a+140 = 2*102

a+140 = 204

a = 204-140

a = 64

-----------------

The angles 102 and c are inscribed angles opposite one another. They add to 180. This is true for any inscribed quadrilateral.

c+102 = 180

c = 180-102

c = 78

-----------------

Another useful rule is that the four angles of any quadrilateral always add to 360.

102+92+c+d = 360

102+92+78+d = 360

272+d = 360

d = 360-272

d = 88

-----------------

The inscribed angle d cuts off the arc a+b

This means 2d is the measure of a+b because of the inscribed angle theorem.

a+b = 2d

64+b = 2*88

64+b = 176

b = 176-64

b = 112

Answer:

A - 17.576

Step-by-step explanation:

All we have to do is replace s with 2.6!

V = s^3

v = 2.6^2

v = (2.6)(2.6)(2.6)

v = 6.76 * 2.6

v = 17.576

So, the volume of the cube is 17.576 feet! :)

-16z+10y=-4

Step-by-step explanation:

There are a total of 20 students in the class (20 dots)

Statement 1 : Exactly 50% of the students scored 80 or higher.

If we count from 80 towards 100, we see that 14 students scored 80 or higher (not 50%) - false.

Statement 2 : More than 30% of the students failed the quiz with a score of less than 70.

There are 5 students who scored a 65 or below, which is 25% of the students (not 30%) - false

Statement 3 : Fewer than 12% of the students scored a 100.

There are 3 students who scored a 100 (15%, more than 12%) - false

Statement 4 : Exactly 75% of the class passed the quiz with a score of 70 or higher

There are 15 students who scored a 70 or more (75%) - true

So, the answer is the 4th option.

Answer:

last one

Step-by-step explanation:

20 dots in total, use as base

9 dots 80 or above, 9/20 does not equal 1/2

5 dots 65 or below, 5/20=1/4<1/3

3 dots on 100, 3/20=15/100>12/100

15 dots 70 or above, 15/20=3/4 true

I did some math and i got this

x = -2

Hello.

In order to solve the equation, we need to isolate x.

First, subtract 1 from both sides:

[tex]\mathrm{7x+1-1=8x+3-1}[/tex]

[tex]\mathrm{7x=8x+2}[/tex]

Now, subtract 8x from both sides:

[tex]\mathrm{7x-8x=8x-8x+2}[/tex]

[tex]\mathrm{7x-8x=2}[/tex]

[tex]\mathrm{-x=2}[/tex]

Now, the minus sign is the same as -1.

In order to isolate x, we need to multiply both sides by -1:

[tex]\mathrm{x=-2}[/tex]

Therefore, the answer is

[tex]\mathrm{x=-2}[/tex]

I hope it helps.

Have a nice day.

Step-by-step explanation:

Answer:

A) see step-by-step

B) (2, 3)

Step-by-step explanation:

Part A

Plot the two linear equations. The point at which they intersect is the solution to the system.

y = 2x - 1

y = 4x - 5

Part B

see attached diagram

To solve algebraically:

equate the equations and solve for x:

⇒ 2x - 1 = 4x - 5

⇒ -2x = -4

⇒ x = 2

Substitute found value for x into one of the equations and solve for y:

⇒ 2(2)- 1 = 3

Therefore, solution is (2, 3)

We will use graphical method

The terms with the correct descriptions are;

1. control group/ first batch

2. Response variable/ height,texture,and taste

3. Explanatory variable/ new brand of yeast

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments refers to what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

We are given that baker is experimenting with a new brand of yeast. He can bakes his first batch of bread using the old brand of yeast that he usually uses and a second batch using the new brand of yeast.

Since baking both batches of bread, he compares the height, texture, and taste of each batch.

The terms with the correct descriptions in the context of this scenario are;

1. control group/ first batch

2. Response variable/ height,texture,and taste

3. Explanatory variable/ new brand of yeast

The equation that represents s, the total number of seventh-grade students at the middle school is given by: Option A: [tex]18 = 0.1s[/tex]

Suppose that the whole thing is of value V.

Then its one-nth part is symbolically written as: [tex]V \times \dfrac{1}{n}[/tex] (V is divided in n equal part, and each part is called one-nth part of V).

For the considered case, we've got the figures as:

Every seventh grade student at considered school takes one language class. It means, if s = Total number of seventh grade student, then:

[tex]\dfrac{s}{7}[/tex]  is the number of students taking language class.

Now, it is said that: One-tenth of the seventh grade students like French, and that they are total 18 in counts.

Writing it symbolically gives:

[tex]\dfrac{s}{10} = 18[/tex]

Since we know that [tex]\dfrac{a}{b} = a \times \dfrac{1}{b}[/tex]

Thus,

[tex]\dfrac{s}{10} = s \times \dfrac{1}{10} = s \times 0.1= 18\\\\0.1 s = 18\\18 = 0.1s[/tex]

(sign of multiplication is often hidden if there are non numeric symbols and numbers being multiplied are written together)

Thus, the equation that represents s, the total number of seventh-grade students at the middle school is given by: Option A: [tex]18 = 0.1s[/tex]
