Answer:

C) 100

Step-by-step explanation:

line AC intersects line DB,

hence ∠AEB and ∠DEC are opposite angles and thus

∠AEB = ∠DEC

5x-10 = 4x+12   (subtract 4x from both sides)

5x - 4x - 10 = 12

x - 10 = 12    (add 10 to both sides)

x = 12 + 10 = 22 degrees

∠DEC = 4x+12

= 4(22) + 12

= 88 + 12

= 100 degrees

Answer:

4

Step-by-step explanation:

7-3=4

then i just messed around with putting numbers to the 4th and got 4

The question asks for a number which, when raised to the 7th power and divided by the same number raised to the 3rd power, results in 256. By understanding the rules of exponents, we find that the number is 4 because 4^4 equals 256.

To solve this problem, it's important to know that when you divide two numbers with the same base and different exponents, you subtract the exponents. So, a number to the 7th power divided by the same number to the 3rd power equals that number to the (7-3)th = 4th power.

Therefore, the question is asking for a number which to the 4th power equals 256. The fourth root of 256 is 4 because 4^4 equals 256. So the answer is 4.

The bakery sold 23 bagels and 12 muffins.

Step-by-step explanation:

Given,

Cost of each bagel = $1.50

Cost of each muffin = $2.00

Total sold = 35

Revenue generated = $58.50

Let,

x be the number of bagels

y be the number of muffins

According to given statement;

x+y=35       Eqn 1

1.50x+2y=58.50    Eqn 2

Multiplying Eqn 1 by 2

[tex]2(x+y=35)\\2x+2y=70\ \ \ Eqn\ 3[/tex]

Subtracting Eqn 2 from Eqn 3

[tex](2x+2y)-(1.50x-2y)=70-58.50\\2x+2y-1.50x-2y=11.50\\0.50x=11.50[/tex]

Dividing both sides by 0.50

[tex]\frac{0.50x}{0.50}=\frac{11.50}{0.50}\\x=23[/tex]

Putting x=23 in Eqn 1

[tex]23+y=35\\y=35-23\\y=12[/tex]

Introduction

Wrestling is a wonderful activity with many advantages for the student-athlete. It is a sport that is highly

competitive, exciting and satisfying. It is a sport that provides for individual and team competition. It is -

and should be - fun. Unfortunately, the practice of losing weight by not eating, restricting fluid intake and

over-exercising reduces the sport's fun. This information is presented to help clear up misconceptions

regarding wrestling and weight loss. I also hope to give some guidance to those who desire to manage

their weight properly in preparation for and during the wrestling season.

History and Stigma

For too long, the wrestling community has unthinkingly accepted the myth that to be a good wrestler, you

must cut weight. The generally accepted thinking is something like this: if your natural weight is 135

pounds, you may be a good wrestler at 135 pounds. But if you wrestle at 130 pounds, you'll be a better

wrestler. And if you can make it down to 125, you'll be a state champion. No facts support that widely held

view, yet wrestlers and parents subscribe to that faulty reasoning. Looking further back, many remember

the days that losing excessive weight was a specific practice and expectation among wrestlers. It was

supposed to teach sacrifice, commitment, and the idea of “No Pain, No Gain.”

Regardless of the current attitude of the majority of the wrestling community, the stigma that an unhealthy

loss of weight is a requirement of wrestling among outside observers sticks. The Virginia High School

League has followed national guidelines to establish rules that encourage healthy weight management

among wrestlers.

Current Regulations

Preseason weight certification is accomplished with three steps. The first is determining each wrestler’s

body fat percentage using skin fold calipers. Next, the wrestler completes a hydration test, to insure

against a dehydrated weight measurement, and the wrestler weighs in. The third step is the calculation of

the wrestler’s minimum wrestling weight based on 7% body fat for males and 12% for females. The

wrestler may not wrestle at a weight class below his minimum weight during the season. The wrestler is

also restricted from losing more then 1.5% body weight loss per week (official weigh-ins at certification,

matches, and tournaments are used for this calculation). A one-pound per month growth allowance is

provided to allow for the natural growth of this age group. The VHSL advises, and we have instituted,

daily weigh-ins before and after practice to monitor weight-loss and dehydration.

Additionally, the National Federation of State High School Associations has adopted several other rules to

guide coaches and wrestlers while managing their weight. Wrestlers are discouraged from wrestling at a

weight class more then one weight class above their certified weight.

The equation that models the situation of a wrestler's varying weight is w = x +/- 3.2, with x representing the normal weight. The minimum weight is 164.8 pounds and the maximum weight is 171.2 pounds.

To write an equation that models the situation, we can use the variables x and w to represent the normal weight and the varying weight, respectively. The equation can be written as w = x +/- 3.2, where the +/- sign represents that the weight can vary by as much as 3.2 pounds. Given that the normal weight is 168 pounds, the minimum weight would be 168 - 3.2 = 164.8 pounds, and the maximum weight would be 168 + 3.2 = 171.2 pounds.

Answer:

The answer is G = 20 - m/18, but none of the answers given is correct.

Step-by-step explanation:

1. Let's review the information given to us to help Lulu to answer the question correctly:

Capacity of the gas tank of Lulu's car = 20 gallons

Lulu can travel 216 miles using 12 gallons

2. Which linear equation represents the number of gallons of gas, G, left in the tank after driving m miles?

G = number of gallons left in Lulu's car

m = Miles driven by Lulu

miles per gallon = 216/12 = 18 miles per gallon

Now, we can write the linear equation, this way:

G = Capacity of the gas tank of Lulu's car - miles driven/miles per gallon

Replacing with the values we know:

G = 20 - m/18

Let's assume Lulu drives 180 miles, using our linear equation, we have:

G = 20 - 180/18

G = 20 - 10 = 10 gallons left

Let's assume Lulu drives 54 miles, using our linear equation, we have

G = 20 - 54/18

G = 20 - 3 = 17 gallons left

Step-by-step explanation:

The complete question is

The length of a snake in a video game doubles every minute. the function f(x)=10*(2)^x represents the length of the snake in centimeters. the time x=0 represents when the game started.

a) label the correct axes with "length (cm)" and"time (minutes)"

b) graph f(x)=10*(2)^x

Part a) we know that

we have a exponential function of the form

[tex]f(x)=a(b^x)[/tex]

where

f(x) -----> the length of a snake in a video game in centimeters

x ----> the time in minutes

a is the initial value or y-intercept of the linear equation

b is the base of the exponential equation

In this problem

[tex]f(x)=10(2^x)[/tex]

so

[tex]a=10\ cm[/tex] ---> initial value, value of y when the value of x is equal to zero[tex]b=2[/tex] ----> factor growth

[tex]b=(1+r)\\r=b-1=2-1=1[/tex]

[tex]r=100\%[/tex] ----> percent rate of change

Is a exponential growth function

Part b) Graph the function

To graph the function we need different points

assume different values of x and find the values of f(x)

For x=0 ---->  [tex]f(0)=10(2^0)=10[/tex] ----> point (0,10)

For x=1 ---->  [tex]f(1)=10(2^1)=20[/tex] ----> point (1,20)

For x=2 ---->  [tex]f(2)=10(2^2)=40[/tex] ----> point (2,40)

For x=3 ----> [tex]f(3)=10(2^3)=80[/tex] ----> point (3,80)

For x=4 ---->  f(4)=10(2^4)=160 ----> point (4,160)

Step-by-step explanation:

In a Cartesian system or a coordinate system, the abscissa is the value of the horizontal (x) value and the ordinate is the value of the vertical (y) value.

So, The sum of the abscissa and the ordinate = x + y when written as an algebraic expression.

Since given that The sum of the abscissa and the ordinate is six

So,  the correct equation is x + y = 6

Answer:

Step-by-step explanation:

(a)

3x - 6y = -12.,......(1)

x - 2y = -8.…......(2)

from equation (2),by adding 2y to both sides, x= -8 + 2y.....(3)

Let's substitute the value of x in equation (1)

3(-8 + 2y) - 6y = -12

-24 + 6y - 6y = -12

6y - 6y = 12..,..(4)

From equation (4) we can see that both equations (1) and (2) has no solutions for x and y

(b)They are two parallel lines of slope of 2 and intercepts on y at 2 and 4

(a) The given system has no solution.

(b) The lines are parallel and never intersect.

To determine the solution of the system of equations using the substitution method, follow these steps:

Substitution Method

Interpretation of Result

Because the system of equations has no solution, we deduce that the lines represented by these equations are parallel and never intersect. Thus, they do not share any common points.

Therefore, the system of equations has no solution, and the lines are parallel.

Applying the 2020 US tax brackets, Sarina would owe $4,842.50 in federal taxes on her $42,000 income.

The amount of federal taxes that Sarina owes on her $42,000 income can be determined by referring to the tax brackets provided by the IRS. In 2020, the federal income tax rates for individuals are as follows:

According to these brackets, Sarina would pay 10% on her first $9,875 and 12% on the remaining amount up to $40,125. Any income she earned over that up to $85,525 would be taxed at 22%. Given that Sarina made $42,000, she falls into the second tax bracket. Therefore, her tax would be calculated as follows:

By adding these amounts together, we can conclude that Sarina would owe $4,842.50 in federal taxes for that year.

Sarina, a single filer earning $42,000 annually, would first deduct the standard deduction to calculate taxable income. Her taxable income of $28,350 would be taxed at 10% for the first $11,000 and at 12% for the next $17,350. The total federal tax owed by Sarina would be $3,182.

The amount Sarina owes in federal taxes depends on the tax rates applied to income brackets. For a single taxpayer earning $42,000 a year, we look at the given tax brackets to calculate the tax owed based on the progressive tax system in the United States.

Since Sarina's income is within the second bracket ($11,001-$44,725), her income will be taxed at different rates for different portions of her income.

First, we subtract a single filer's standard deduction to determine her taxable income. Let's assume the current standard deduction is similar to the $13,650 mentioned.

Calculate taxable income:

Total Income: $42,000

Standard Deduction: $13,650

Taxable Income: $42,000 - $13,650 = $28,350

Now, we split the taxable income according to the tax brackets:

First $11,000 are taxed at 10%: $1,100

Next $17,350 ($28,350 - $11,000), taxed at 12%: $2,082

Total tax owed = $1,100 + $2,082 = $3,182.

The complete question is:

Step-by-step explanation:

Consider A=60°, B=50°, C=y°=???

So, according to the measurement of angles of a triangle.

A+B+C= 180°

60°+80°+C= 180°

140°+C=180°

C=180°-140°

C=y°=40°

So, x is also 40° since x and y are vertically opposite angles.

Area = side*side = y * y = y²

the area of ​​the triangle exceeds the rectangle by 39 cm².

2y² + 10y - y² = 39

y² + 10y = 39

y² + 10y -39 = 0

y² +13y - 3y - 3*13 = 0

y(y+13) -3(y+13)=0

(y+13)(y-3) = 0

y  + 13 = 0  will not come as length couldn't be in negative

y - 3 = 0
