Find x if AC = -7+2x, BC =9, and AB = -27 + 3x

Given :

Peyton is taking a multiple choice test with a total of 20 points available. Each  question is worth exactly 2 points.

To Find :

Peyton's test score (out of 20) if  she got 4 questions wrong.

Solution :

Total numbers of questions are 20/2 = 10 questions.

Points after getting 4 questions wrong :

P = 2( 10 - 4 )

P = 12

Therefore, her score after getting 4 questions wrong is 12.

Hence, this is the required solution.

Answer:

Score with questions wrong:20-2(x)=12

Score with x questions wrong: 20-2x

Step-by-step explanation:

Since Peyton loses 2 points for every question wrong, she would lose 2 x 4, or 8 points when getting 4 questions wrong. Since the test is out 20 points, her final score would be 20-8 or 12 points. (Note, this is an answer for delta math.)

0.003L

Step-by-step explanation:

Divide by

1000

This is a case of the metric system. To convert from "milli-" to the standard unit, such as meters or liters, we divide by

1000

One milliliter is equal to a thousandth of a liter, and one liter is equal to one thousand milliliters.

3ML=0.003L

Answer:

12 square feet

Step-by-step explanation:

The shape of the top of the desk is a trapezoid.

A = (b1 + b2)h/2

A = (5 ft + 3 ft)(3 ft)/2

A = (8 ft)(3 ft)/2

A = 24 ft^2/2

A = 12 ft^2

Answer: 12 square feet

The statement is false. A conjecture is proven through deductive reasoning.

Step-by-step explanation:

The required width of Amy's kitchen would be 8 ft.

Given that,
The measurement of Amy's rectangular kitchen is 12 feet. If the area of the room is at least 96 square feet, To determine the least width the room could have.

The rectangle is a four-sided geometric object with equal-length opposites and 90° angles on each side.

Here,
let the width be x,
according to the question,
area of the kitchen = 96
length × width = 96
12 × x = 96
x = 96 / 12
x = 8

Thus, the required width of Amy's kitchen would be 8 ft.

Answer:

5 times greater.

Step-by-step explanation:

1.7 x 10^6 = 1700000.

3.4 x 10^5 = 340000 .

1700000 / 340000  = 5.

Approximately five times greater is 1.7 × 10⁶ than 3.4 × 10⁵ which is determined by the division operation.

Mathematical operations can also be described via subtraction, division, and multiplication built-in functions. The arithmetic operator is the operator who conducts the operation.

* Multiplication operation: Multiplies values on each side of the operator.

For example, 12 = 2 × 4

/ Division operation: divides left operand by right operand

For example, 4/2 Equals 2.

We have been given data:

⇒ 1.7 × 10⁶ = 1700000

⇒ 3.4 × 10⁵ = 340000

Now we have to take a ratio of 1700000 and 340000

⇒ 1700000 / 340000

Apply the division operation, and we get

⇒ 5

Therefore, approximately five times greater is 1.7 × 10⁶ than 3.4 × 10⁵.

Answer:

23.4 years

Step-by-step explanation:

The exponential growth model is

A = P(1 + r)^5t, where r is the annual growth rate as a decimal fraction.

If the original number (P) is to double, then this model becomes

2P = P(1 + 0.03)^t, or 2 = 1.03^t.  Solve this for t by taking the log of both sides:

log 2 = t*log 1.03, or

Step-by-step explanation:

Given that a flyer begins from earth and thrown up with a velocity of 30 ft/sec vertically.

u = initial velocity = 30 :   a = -g = 32 ft/sec^2

s(0) =initial height  =4 ft.

We have the equation

where u = initial velocity : v= final velocity : s = distance travelled and a = acceleration.  Here final velocity is found out as follows

Substitute to get

Since v cannot be negative, the flyer’s center of gravity cannot ever reach 20 feet.

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

To reach 25 ft, put s = 25

and v must be atleast 0

Then we have  

Hence if thrown with initial velocity of 40 ft /sec, it will reach a height of 25 ft.
