C) 44 inches

D) 66 inches

Answers

Answer 1
Answer:

If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.

What is Algebra?

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

The height of an ostrich is 20 inches more than 4 times the height of a kiwi.

Let y be the height of the ostrich and x be the height of a kiwi. Then the equation is given as,

y = 4x + 20

If an ostrich is 108 inches tall. Then the height of the kiwi will be

108 = 4x + 20

4x = 88

x = 22

If an ostrich is 108 inches tall. Then the height of the kiwi will be 22 inches. Then the correct option is A.

Answer 2
Answer: h=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k

k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k

answer is A

to find the height in feet, c, of the cactus. Show your work.

Answers

Answer:

c = 3.7

Step-by-step explanation:

c + 1.2 = 4.9

c = 4.9 - 1.2

c = 3.7

The tangent line to the graph of y = h(x) at the point (-1, 6) passes through the point (4, 2). Find h(-1) and h'(-1).How do I solve this?

Answers

Answer:

h(-1)=7

point slope formula y-y1=m(x-x1), m slope, (x1,y1) point

slope is 2/10=1/5

y-9=(1/5)(x-9)=(1/5)x-(9/5)

y=(1/5)x+(36/5) the equation of the tangent line.

Step-by-step explanation:

The slope of the tangent line is the derivative of h(x). That is the slope of the line which is (1/5). The previous -1/5 was in error.

If m∠ABC = 72°, what is m∠DAB?

Answers

Value of ∠DAB is 108°

Intersection of Parallel lines:

Given that;

∠ABC = 72°

Find:

Value of ∠DAB

Computation:

We know that Line AD is parallel to line CB

So,

∠ABC + ∠DAB = 180°

72° + ∠DAB = 180°

∠DAB = 108°

Find out more information about 'Parallel line'

brainly.com/question/19300779?referrer=searchResults

Answer: m∠DAB=72

Step-by-step explanation:

Since we have given that

∠ABC = 72°

Since the lines AD and BC are parallel to each other,

As we know that when the two parallel lines cut by a transversal then the corresponding angles will  be formed.

And the corresponding angles will be equal.

So, m∠ABC =m∠DAB=72°

Hence, m∠DAB=72°
