Help with math please, just 7 and 9. Please explain thanks.

Answers

Answer 1

Answer: #7 x=16 #9 x=27

Step-by-step explanation:

This is an isosceles triangle, so the angles formed at the base of the congruent sides are equal.

5x-7=8x-55

48=3x

16=x

This is an equilateral triangle (if 2 angles are 60, the third has to be 60 as well) so the sides are equal

7x+19=11x-89

108=4x

27=x

t = p + 50
The variable p represents the number phone calls she routes, and the variable t represents
the number of minutes she is on the phone. In all, how many phone calls does Shivani have
to route to spend a total of 93 minutes on the phone?

Answers

The only way i can think of working out this question is this:

t = time p = phone calls

insert what we know:-

93 = p + 50

make P on its own:-

take away 50 from each side

43 = p

switch (you don’t HAVE to do this) :-

p = 43

So, shivani has to route a total of 43 phone calls to spend a total of 93 minutes on the phone.

A traoezoid has basses of 36 1/2 noches and 13 1/2 noches and a height of 10 1/2 inches.What is the área of the trapezoid in square inches?

Answers

Answer:

Area of trapezoid = 262.5 inches²

Step-by-step explanation:

Given:

Larger Base = [tex]36\frac{1}{2}[/tex] inches = 36.5 inches

Smaller Base = [tex]13\frac{1}{2}[/tex] inches = 13.5 inches

Height of trapezoid = [tex]10\frac{1}{2}[/tex] inches = 10.5 inches

Find:

Area of trapezoid

Computation:

Area of trapezoid = [Sum of parallel line / 2]Height

Area of trapezoid = [(a+b) / 2]h

Area of trapezoid = [(36.5 + 13.5) / 2]10.5

Area of trapezoid = [(50) / 2]10.5

Area of trapezoid = [25]10.5

Area of trapezoid = 262.5 inches²
