∠1 and ∠2 are adjacent right angles.
∠1 and ∠3 are vertical angles.
What is the measure of ∠1 plus the measure of ∠3 minus the measure of ∠2?

Answers

Answer: If 1 and 2 are adjacent right angles, they are both 90º.

1 and 3 are vertical, which means they must be congruent, so 3 is also 90º

So: 90 + 90 - 90 = 90

What is the area of the trapezoid?

Answers

78. you can find the area of the two ends which are triangles by subtracting 11 from 15. Then divide that four by two since both ends are included. Multiply 2 by 6 to get half the area of one triangle. But since there are two just leave that number as is. Finally multiply 11 by 6 to get the rest of the area.

Answer:

A=78ft

Step-by-step explanation:

The area of a trapezoid is A=(a+b)/2 *h

a=long base

b=short base

h=height

For your trapezoid, it will look like this:

a=15ft

b=11ft

h=6ft

Let's add those into the equation:

A=(15+11)/2 *6

Okay, let's solve it! Using PEMDAS, we know parenthesis are first.

A=26/2 *6

Now we divide!

A=13*6

Multiply! And don't forget to add your unit.

A=78ft

A fitness club charges a onetime $75 initiation fee plus $30 each month for a member to maintain her membership. Which equation below models the total cost, c, the club charges as a function of the number of months, m, that the individual has maintained her membership?

1) c = 75m + 30
2) c = 1/30m + 75
3) c = 30m + 75
4) c = 900 + 30m

Answers

Answer:

c = 30m + 75

Step-by-step explanation:

Because the 75 dollars is only one time you add that to the total. Because it is 30 dollars PER MONTH and m is the number of months you would multiply those two in order to know how much you would be paying!

What is the value of r of the geometric series?

Answers

Answer:

A) 0.8

Step-by-step explanation:

0.8 on edge.

The value of r of the geometric series is 4/5.

What is geometric series?

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The nth term of a geometric progression is expressed as

Tₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

Given the formula for the geometric series expressed as

[tex]_3\\\sum{1.3(0.8)^n^-^1}\\n=1[/tex]

Comparing both equations

rⁿ⁻¹ = (0.8)ⁿ⁻¹

r = 0.8

r = 8/10

r = 4/5

Hence, the common ratio is 4/5.

cupcakes in 30 minutes. If Alexis continued decorating cupcakes at
this rate, how many cupcakes would she decorate in 2 hours?
Johnny said that Alexis would be able to decorate 18 cupcakes in 2
hours. Is Johnny correct? If not, explain his mistake and identify the
correct solution.

Answers

Answer:

Incorrect

Step-by-step explanation:

because it takes 30 min to bake 9 which is half an hour, and if if you multiply 9 by 4 which 30 mins each it would be 36 cupcakes in 2 hours.

about 36 cupcakes in two hours, johnny is incorrect because it would be 18 cupcakes per ONE hour.

What is similarity of triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent. Triangle resemblance is shown here by the symbol "≈"

Given that,

One right angle triangle, ΔAEC

one segment BD which is intersecting sides AC & AE

ΔAEC has one similar triangle inside, which is ΔADB

Triangle ΔAEC and ΔADB similar,

So, we can say ΔAEC ≈ ΔADB

For the given similar triangles,

we can use angle-angle similarity property,

so, AE/AC = AD/AB

⇒ (3+6)/(x + y) = 3/x

⇒9/(x + y) = 3/x

Hence, the Statement C is correct
