Solve 64 = h + 30.
K=?

Answers

Answer:

h = 34

Step-by-step explanation:

64=h+30

Step 1: Flip the equation.

h+30=64

Step 2: Subtract 30 from both sides.

h+30−30=64−30

h=34

Assuming you meant “h =?” instead of “K=?”. In that case,
h = 34.

To find this answer, you just subtract 30 from 64, isolating h on it’s own side. Or imagine the problem arranged “h + 30 = 64.”

A rectangle with an area of 16 square units is drawn on a coordinate grid. The rectangle is
dilated by a scale factor of 1.5 with the origin as the center of dilation.
If (x, y) represents the location of any point on the original rectangle, which ordered pair
represents the coordinates of the corresponding point on the resulting rectangle?
A (16x, 16y)
B (16 + x, 16+y)
C (1.5x, 1.5y)
D (1.5 + x, 1.5 + y)

Answers

Answer:

Just multiply x and y by the scale factor

Step-by-step explanation:

The corresponding points on the resulting rectangle will be 1.5x and 1.5y. Hence, option C is correct.

What is the area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the number of unit squares that completely encompass the surface of a compact figure. The squared unit, which is frequently expressed as inches, square feet, etc., is the accepted unit of area.

As per the data given in the question,

The area of the square is 16 square units.

Now, the scale factor is 1.5.

Then, the corresponding point at the x-axis will be 1.5x

Also, the corresponding point on the y-axis will be 1.5y.

Of the last 60 people who went to the cash register at a department store, 15 had BLOND hair,
17 had BLACK hair, 26 had BROWN hair, and 2 had RED hair. Determine the experimental
probability that the next person to come to the cash register has BLOND hair. (answer as
simplified fraction)

Answers

Answer:

[tex]P(Blond) = \frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]Total = 60[/tex]

[tex]Blond = 15[/tex]

[tex]Black = 17[/tex]

[tex]Brown = 26[/tex]

[tex]Red = 2[/tex]

Required:

Determine the experimental probability of the next person having blond hair

This is calculated by dividing the number f people having blond hair with the total number of people.

i.e.

[tex]P(Blond) = \frac{Blond}{Total}[/tex]

[tex]P(Blond) = \frac{15}{60}[/tex]

Simplify

[tex]P(Blond) = \frac{1}{4}[/tex]

exam. What was the average grade on the midterm exam for the entire class?

Answers

Answer:

They average 84%

Step-by-step explanation:

Just add 77 and 91 then divide it by 2. Hope this helps.

Answer:

83 is the correct answer if you just do it by adding 91 and 77 then diving it by 2 you would get 84 that is not what answer they are looking for. Took the test 83 is what they are looking for they want you to do the work.

Tenth graders 12*77= 924

Eleventh graders 9*91= 819

924+819= 1,743

12 tenth graders and 9 eleventh graders

12+9 = 21

When renting a limo for prom, the number of people varies inversely with the cost per person. Originally there were 4 people and the cost per person was $57. If the number of people changed to 12, what would be the new cost per person?

Answers

Answer:The new cost per person= $19 when there are 12 people

Step-by-step explanation:

Step 1

Let Number of people be rep as N

And Cost per person = C

such that the relationship of  number of people which varies inversely with the cost per person is given as

N∝ 1/C

Introducing constant of proportionality, k, we have that

N= K/C

such that when there were 4 people the cost per person was $57, K would be

N= K/C

4 = K /57

k= 57 X 4

k=228

Step 2

Therefore If the number of people changed to 12, cost per person would be

N= K/C

12= 228 / C

C= 228/12

C= 19

The new cost per person= $19 when there are 12 people

The diameter of a pizza is 14 inches what is the circumference of the pizza use 3.14

Answers

Answer:

43.96 in.

Step-by-step explanation:

A pizza is found in shape. Therefore, we would apply the formula for the circumference of a circle to find the circumference of the pizza.

Circumference = 2πr

r = ½ of diameter = ½*14 = 7 in.

π = 3.14

Circumference = 2*3.14*7

Circumference of the pizza = 43.96 in.

An airplane is currently flying at an altitude of 37,000 feet. The airplane is scheduled to land at an airport 100 miles

away. Find the average angle at which the airplane must descend for landing. Round your answer to the nearest

degree.

Answers

Answer:

4degrees

Step-by-step explanation:

Given the following

Height of the airplane = 37000feet

distance covered on landing = 100miles = 100(5280)

distance covered on landing  = 528,000feet

Using the SOH CAH TOA

sin theta = opposite/hyp

sin theta = 37000/528000

sin theta = 37/528

theta = arcsin (37/528)

theta = 4 degrees

Hence average angle at which the airplane must descend for landing is 4degrees

Given that 4x - 5y = 12 find y when x= -3

Answers

Answer:

y ⁻²⁴⁄₅ or - 4.8

Explanation:

4x - 5y = 12

x = -3

Insert -3 for 'x' in the equation

4(-3) - 5y = 12

Remove the parentheses: (-a) = -a

-4 · 3 - 5y = 12

Multiply 4 · 3: 12

-12 - 5y = 12

Add 12 to both sides of the equation

-12 - 5y + 12 = 12 + 2

Simplify

-5y = 24

Divide both sides by -5

-5y / -5 = 24 / -5

Simplify

y = ⁻²⁴⁄₅

Turn the fraction into a decimal

y = -4.8
