On a test a student got 15 problems correct out of a total of 20 problems. What percent did the student get, begin emphasis, incorrect, end emphasis,?

Answers

Answer:

I think what you got is correct

The percentage of incorrect problems is 25%.

Option D is the correct answer.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of problems = 20

Number of correct problems = 15

The number of incorrect problems.

= 20 - 15

= 5

The percentage of incorrect problems.

= 5/20 x 100

= 25%

Thus,

25% were incorrect problems

ANSWER ASAPPPP PLZZZZ MARKING BRAINLIEST HELPPP

Answers

Answer:

12.72 dollars per hour

Step-by-step explanation:

Her original money is $12 per hour. We know that 6% in a decimal is 0.06. But if we multiply 0.06 and $12, it would get an answer that is decreasing than increasing. So we can get this equation. 12+0.06*12. ( 12 dollars plus 6% of 12 dollars)  If we divide by 12, we get: 12( 0.06+1). 0.06+1=1.06. And 1.06*12 is 12.72 dollars per hour now.  I hope this helps your question!

Answers

The total saved amount for Jorge, Janet and Rob is $55.8

Mathematical Expression

Mathematical Expressions are statements that have at least two terms that include numbers, variables, or even both, and are linked by an operator.

How to solve mathematical expression for the given condition?

Jorge has saved $ 15.50

Janet's saving is [tex]\frac{1}{5}\times \$15.50[/tex]

That is, Janet has saved [tex]\$3.1[/tex]

Rob's saving is [tex]12\times\$3.1[/tex]

Thus, Rob has saved [tex]\$37.2[/tex]

So, the mathematical expression for the total saved amount of all three is given below.

$15.50 + $3.1 + $37.2 = $55.8

Simplify the above mathematical expression.

Therefore, The total saved amount for Jorge, Janet and Rob is $55.8

Ricky draws a square . He claims that any rotation about the center of the square that is a multiple of 30 degrees will carry the square onto itself . Which statement best describes Ricky's claim ?

Answers

Answer:

Option (a)

Step-by-step explanation:

This question is incomplete without statements; find the statements as followed,

a). Ricky's claim is incorrect since not all rotations that carry a square onto itself are multiples of 30 degrees.

b). Ricky's claim is incorrect since not all rotations that are multiples of 30 degrees carry a square onto itself.

c). Ricky's claim is correct since any rotation that carries a square onto itself is a multiple of 30 degrees.

d). Ricky's claim is correct since any rotation that is a multiple of 30 degrees carries a square onto itself.

Square ABCD will map onto itself when point A comes to B, C or D by a rotation about the center E with a multiple of measure of angle AEB.

m∠AEB = 90° [Diagonals of a square intersect each other at 90°]

In simpler words, if square ABCD is rotated 90° or it's multiple about the center E, square will overlap itself.

Therefore, Option (a) is correct.

Suppose f(x) = x2 and g(x) = 5x2. Which statement best compares the graph of g(x) with the graph of f(x)?

A.
The graph of g(x) is the graph of f(x) horizontally stretched by a factor of 5.

B.
The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5.

C.
The graph of g(x) is the graph of f(x) vertically compressed by a factor of 5.

D.
The graph of g(x) is the graph of f(x) shifted 5 units right.

Answers

Answer:

B. The graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

Step-by-step explanation:

It is a quadratic and in the form:

f(x) = a(x-h)^2 + k

In this case a = 5, and if a is greater than  1, then the parabola is vertically stretched. It is not vertically compressed because a is not less than 1.

h and k are irrelevant because there are no horizontal or vertical shifts in the graph.

Therefore, when compared to f(x) = x^2, the graph has only been vertically stretched by a factor of 5.

Answer:

the graph of g(x) is the graph of f(x) vertically stretched by a factor of 5

Step-by-step explanation:

d)P=2(l+b)

90=2(l+b)

l+b=90/2

l+b=45

A=l×b

500=lb

l=45-b

500=(45-b)b

500=45b-b²

b²-45b+500=0

(b-20)(b-25)=0

b=20 or b=25

a+b=9

a=9-b
