Find the highest common factor (HCF) of 90 and 48.
Answer:
The answer is 6
Step-by-step explanation:
The highest common factor between the numbers is 6.
What is the greatest common factor?The greatest common factor is the largest positive number which can be divided into given numbers evenly.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the two numbers are 90 and 48. The highest common factor will be calculated as,
90 = 2 x 3 x 3 x 5
48= 2x2x2x2x3
The common numbers are 2 x 3 = 6
Therefore, the highest common factor between the numbers is 6.

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.
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

Jorge has saved $15.50. Janet saved 1/5 of the amount that Jorge saved. Rob saved 12 times as much of Janet. What is the total saved amount of all three. (please show the answer and how you got it please)
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]

Tyreek Hill is the fastest player in the NFL, running a 40 yar dash in 2.4 seconds. Using the rate, 38 yards for every 4 seconds: How many yards can he run in 12 seconds?
Answer:
He can run 112 yards in 12 seconds
Step-by-step explanation:
Here, we want to know the number of yards he can run in 12 seconds
From the question, we are told that his running rate is 38 yards in 4 seconds
So the number of yards he can run in 12 seconds will be;
38 * 12/4
= 38 * 3 = 114 yards
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,?
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

Liam bought 2 vintage movie posters, 2 rock posters, and 1 rap poster. He applied a $35 gift card to the total purchase and a 1/2-off coupon to the rap poster. Write and evaluate a numerical expression to show how much Liam paid for the posters.
Vintage Movie: $28.50
B Movie: $18.25
Rock: $29.75
Rap: $19.50
Answer:
the vintage movie posters and the 2 rock posters could be priced the same, $8.
8 x 4 = 32.
the rap poster could be $6, but with the half-off coupon it comes to $3
32 + 3 = 35
assuming the gift card covers the total cost, this reasoning is correct.

shawna is making a $12 per hour. she gets a 6% increase in pay.
ANSWER ASAPPPP PLZZZZ MARKING BRAINLIEST HELPPP
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.

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 ?
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.
