The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
Answers
Answer:
Base = 18 inches
Height = 54 inches
Step-by-step explanation:
The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
The area of a parallelogram is given as:
Base × Height
Height = h = 3b
Area = 972 square inches
We substitute
972 = b × 3b
972 = 3b²
Divide both sides by 3.
b² = 972/3
b² = 324
b = √324
b = 18 inches
Solving for h
h = 3b
h = 3 × 18
h = 54 inches
Therefore,
Base = 18 inches
Height = 54 inches

What is another way that you could write the ratio of pennies to quarters?
Answers
Answer:
1/100 to 25/100
or
0.01 to 0.25
Step-by-step explanation:
Pennies are also known as one per cent. Cent refers to 100 and pennies are called one per cent because they value 1 out of 100. 100 pennies equal one dollar.
Similarly, one quarter is 1/4 of a dollar and 1/4 equals 25/100 when multiplying the numerator and denominator by 25.

What is the inverse of the function f(x) = x +3? 1 O h(x) = = x + 3 3 5x+3 = Oh(x) = rx - 3 3 Oh(x) = x-3 O h(x) = x + 3
Answers
Answer:
C
Step-by-step explanation:
the inverse of x+3 is x-3
The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x)= x + 3
Now, We can find the inverse function as;
⇒ f (x) = x + 3
⇒ y = x + 3
Solve for x;
⇒ x = y - 3
Substitute y = x and x = h (x);
⇒ h (x) = x - 3
Thus, The value of the inverse of the function f(x) = x +3 is,
⇒ h (x) = x - 3

What is the 22nd term of the arithmetic sequence 12 , 17 , 22 , 27 , .... , .... , ....
Answers
Answer: 117
Step-by-step explanation:
Formula for arithmetic sequence is:
= a + (n - 1)d
22nd term = a + (n - 1)d
= a + (22 - 1)d = a + 21d
where, a = 12
d = 17 - 12 = 5.
Therefore, 22nd term will be:
= a + 21d
= 12 + 21(5)
= 12 + 105
= 117
The 22nd term is 117
