Answer B for me please!!! I need help. What assumption would you need to make to make about the diagram in order to assume that the measure of angle 1 is congruent to the measure of angle 3?

Answer:

b

Step-by-step explanation:

Answer:

Would it be b) 15/7

Step-by-step explanation:

Answer:

3.5%

Step-by-step explanation:

Given data

A=$6225

P=$5000

T= 7years

R=???

Simple interest

A=P(1+rt)

substitute

6225=5000(1+7r)

6225=5000+35000r

collect like terms

6225-5000=35000r

1225=35000r

r= 1225/35000

r=0.035

Hence the rate is 0.035*100= 3.5%

Answer:

it would be 2m and 5n

Step-by-step explanation:

because 4 * 2 is 8 for m

and 4*5 is 20 for n

Answer:

4(2m - 5n)

4×2m - 4×5n

8m-20n

Therfore ans are 2m and 5 n

Answer:

n=68

m=180-(68+68)

m=180-136

m=44

Answer:

m=44 n=68

Step-by-step explanation:

Base angle theorum.

180-(68+68)= Angle opposite to M=44

Vertical Angle Theorum.

M=Angle opposite to M=44

Definition of Isoceles Triangle.

n=(180-44)/2=136/2=68

Given:

The LCM of two numbers is 14 times their HCF.

The sum of LCM and HCF is 600.

One number is 280.

To find:

The other number.

Solution:

Let HCF of two numbers be x.

The LCM of two numbers is 14 times their HCF.

LCM = 14x

The sum of LCM and HCF is 600.

[tex]14x+x=600[/tex]

[tex]15x=600[/tex]

[tex]x=\dfrac{600}{15}[/tex]

[tex]x=40[/tex]

So, HCF = 40 and the LCM is

[tex]LCM=14(40)[/tex]

[tex]LCM=560[/tex]

We know that, if a and b are two numbers, then

[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]

One number is 280.

[tex]280\times b=560\times 40[/tex]

[tex]b=\dfrac{560\times 40}{280}[/tex]

[tex]b=2\times 40[/tex]

[tex]b=80[/tex]

Therefore, the other number is 80.

Answer: 13.64%

Step-by-step explanation:

Alyssa estimates that the gym can hold 660 students even though it can hold 750.

Her percent error is calculated by:

= (Actual seats - Estimated seats) / Estimated seats

= (750 - 660) / 660

= 90 / 660

= 0.1364

= 13.64%

a^n + a^n+1

rewrite a^n+1 as a^1 a^n

now you have a^n + a^1a^n

Factor out the common term to get the final answer:

a^n (1+a)

Answer:  if Lisa has  ?  sheets of paper and she uses 100 sheets and has 40 sheets left how many sheets of paper did she start with

Answer:

Rate of the Eastbound train is 93 mph.

Step-by-step explanation:

Let the speed of the Eastbound train = x miles per hour

And the speed of the West bound train = y mph

Eastbound train travels 14 mph slower than the westbound train,

So the equation will be,

y - x = 14 ----------(1)

If these trains are 400 miles apart after 2 hours,

Distance traveled by the Eastbound train = Speed × Time

                                                              = 2x miles

Distance traveled by the Westbound train = 2y miles

Trains are 400 miles apart after 2 hours,

So the equation will be,

2y + 2x = 400

x + y = 200 ----------(2)

By adding equation (1) and equation (2)

(y - x) + (x + y) = 14 + 200

2y = 214

y = 107 mph

From equation (1)

107 - x = 14

x = 107 - 14

x = 93 mph

Therefore, rate of the Eastbound train is 93 mph.

Answer:

let two number be x and y

by question

x+y=5….....(1)

xy=6

x=6/y.........(2)

putting the value of x in equation 1

6/y+y=5

6+y²=5×y

y²-5y+6=0

y²-3x-2x+6=0

(y-3)(y-2)=0

either

y=3

or

y=2

:.required no is 2 and 3

Answer:

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Step-by-step explanation:

Answer:

2 or b

Step-by-step explanation:

Total number of orders served by Maya, Ahmad and Joe on Moday = 75

Let the number of orders Maya served be x.

Then :

Number of orders Joe served = 2x

Number of orders Ahmad served = x - 5

This can be written in an equation as :

[tex] \tt \: 2x + x - 5 + x = 75[/tex]

[tex] = \tt 4x - 5 = 75[/tex]

[tex] = \tt 4x = 75 + 5[/tex]

[tex] = \tt 4x = 80[/tex]

[tex] = \tt \: x = \frac{80}{4} [/tex]

[tex] = \tt \: x = 20[/tex]

Which means :

Number of orders Joe served :

= 2 × 20

= 40

Thus, Joe served 40 orders.

Number of orders Maya served = 20

Number of orders Ahmad served :

= 20 - 5

= 15

Thus, Ahmad served 15 orders.

since it is a semicircle, cut that number in half.

Answer:

25.12units squared

Step-by-step explanation:

A = [tex]\frac{\pi r^2}{2}[/tex] or [tex]\frac{3.14r^2}{2}[/tex]

r = 4

3.14 x 4^2 = 50.24

50.24/2 = 25.12

Answer:

The solution to the system of equations is:

The graph is attached below.

Step-by-step explanation:

Given the system of equations

[tex]2y = 2x - 8[/tex]

[tex]2x + y = 5[/tex]

Let us solve the system of equations using the elimination method

[tex]\begin{bmatrix}2y=2x-8\\ 2x+y=5\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}2y-2x=-8\\ y+2x=5\end{bmatrix}[/tex]

Multiply y + 2x = 5 by 2:  2y + 4x = 10

[tex]\begin{bmatrix}2y-2x=-8\\ 2y+4x=10\end{bmatrix}[/tex]

subtracting the equations

[tex]2y+4x=10[/tex]

[tex]-[/tex]

[tex]\underline{2y-2x=-8}[/tex]

[tex]6x=18[/tex]

solve 6x = 18 for x

[tex]6x=18[/tex]

Divide both sides by 6

[tex]\frac{6x}{6}=\frac{18}{6}[/tex]

simplify

[tex]x=3[/tex]

For 2y - 2x = -8  plug in x = 3

[tex]2y-2\cdot \:3=-8[/tex]

[tex]2y-6=-8[/tex]

Add 6 to both sides

[tex]2y-6+6=-8+6[/tex]

Simplify

[tex]2y=-2[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}=\frac{-2}{2}[/tex]

Simplify

[tex]y=-1[/tex]

Therefore, the solution to the system of equations is:

The graph is attached below.

Answer:

$45

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION BELOW;

For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?

$5 was given for participants of the walk-a-thon.

$2 was given for every miles won

Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y

The Total amount that can be given

= (5 + 2y)

Where "y" is the miles value

Then, if you walk for 20 miles, The Total amount that can be given

= 5 + 2(20)

= 5+ 40

= $45
