Find measure of angle EFG

Answers

102degree if you want to know the detail just ask me
First, you know that angle EFG is 17x degrees 
You also know from the supplementary angles that 17x+13x should be equal to 180. 

So, 
17x+13x=180 
30x=180 
x=180/30 
x=6 

Therefore 17(6)= 102 degrees

Complete the chart and determine the solution of the equation f(x) = g(x)?

A.) x = -1


B.) x = 0


C.) x = 2


D.) x = 25

Answers

Answer:

  x = -1.75 makes f(x) = g(x)

Step-by-step explanation:

See the attached for a table. You will notice that for x=-1.75, the values of f(x) and g(x) are the same. That means x = -1.75 is the solution to f(x)=g(x).

Upon calculating the values for f(x) and g(x), it's determined that f(x) = g(x) when x = -7/4. The options provided do not include this answer, suggesting a possible typo in the question or answer choices.

Completing the Values and Finding the Solution for f(x) = g(x)

To complete the given table, we need to apply the functions f(x) = 9x + 7 and g(x) = 5x to the missing x values. For x = -2, g(x) equals -10 (since 5 * -2 = -10). For x = 0, f(x) is 7 (since 9 * 0 + 7 = 7), and for x = 2, f(x) equals 25 (since 9 * 2 + 7 = 25) and g(x) equals 10 (since 5 * 2 = 10).

To determine the solution for the equation f(x) = g(x), we set the two expressions equal to each other:

9x + 7 = 5x

By subtracting 5x from both sides, we get:

4x + 7 = 0

Now, subtracting 7 from both sides, we find:

4x = -7

Finally, by dividing both sides by 4, we get:

x = -7/4

None of the given options A, B, C, or D match x = -7/4, which might indicate there could be a typo in the question or answer choices.

Joanna bought 1 1/2 pounds of apples, 3/4 pound of strawberries, 1/2 pound of grapes, 1 3/4pounds of oranges, and 1 1/4 pounds of pears. How many pounds of fruit did Joanna buy in all?

Answers

The key word ''in all'' means total so this calls for addition so we need to add all fractions first to get our answer.

First we need to add all whole numbers
next we need to find the LCD of all fractions which is 4
next we change the denominators into the LCD (4)
next we join them all together so now it will be 3 + 2 + 3 + 1 + 3 + 2 over 4
since 2 + 3 + 1 + 3 + 2 equals 11 we simplify it to 3 + 11/4
now we make 11/4 to a mixed fraction which is 2 3/4
now we add 3 + 2 to make 5 and keep the fraction

Answer: Joanna bought 5 3/4 pounds of fruit in all.




Joanna bought 5 3/4 pounds of fruit in all if Joanna bought 1 1/2 pounds of apples, 3/4 pounds of strawberries.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

Joanna bought 1 1/2 pounds of apples, 3/4 pounds of strawberries, 1/2 pounds of grapes, 1 3/4pounds of oranges, and 1 1/4 pounds of pears.

= 1 1/2 + 3/4 + 1/2 + 1 3 /4 + 1 1/4

= 3/2 + 3/4 + 1/2 + 7/4 + 5/4

= (6 + 3 + 2 + 7 + 5)/4

= 23/4

= 5 3/4

Thus, Joanna bought 5 3/4 pounds of fruit in all if Joanna bought 1 1/2 pounds of apples, 3/4 pounds of strawberries, 1/2 pounds of grapes, 1 3/4pounds of oranges, and 1 1/4 pounds of pears.

Approximately how many times greater is 8.5×108 than 3.4×105 ? A 2.5 B 250 C 2,500 D 25,000

Answers

it is approximately 2.5 times greater

Solution:

we have been asked to find that , how many times one number is to the other given numbers.

To do this we will divide the larger number by the smaller number and the resulting number will be the answer of the question.

Here the larger number is [tex]8.5\times10^8[/tex]

The smaller number is [tex]3.4\times 10^5[/tex]

Now lets divide as follows

[tex]\frac{8.5\times10^8}{3.4\times 10^5} =\frac{8.5}{3.4}\times 10^{8-5}\\ \\\frac{8.5\times10^8}{3.4\times 10^5} =2.5\times10^3=2500[/tex]

Hence the correct option is C.

The measurement of the supplement of an angle is 7 times the measure of the complement. find the measure of the complement

Answers

x = angle 90 - x = measure of complement of x 180 - x = measure of supplement of x From the information given in the problem, we get this: 180 - x = 7 (90 - x) 180 - x = 630 - 7x -x + 7x = 630 - 180 6x = 450 x = 450/6 x = 75. Now we prove that x = 75° is the correct angle: x = 75° = measure of angle 90° - 75° = 15° = meaure of complement 180° - 75° = 105° = 7 (15°)

Answer:

15⁰

Step-by-step explanation:

Angke = x

Complement = 90 - x

Supplement = 180 - x

Given:

180 - x = 7 (90 - x)

180 - x = 630 - 7x

6x = 450

x = 75

Complement = 90 - 75 = 15⁰

Find the value of x that makes m ∥ n

Answers

Answer:

The value of x that makes m || n is x = 20

Step-by-step explanation:

Given a line that is intersected by another two lines (for example line ''m'' and line ''n'' like in the exercise) one of the conditions that makes m || n is that the alternate interior angles must be congruent. Understanding that congruent means the same.

In the exercise, one pair of alternate interior angles are (2x+20)° and 3x°.

We need this two angles to be congruent ⇒ [tex]3x=2x+20[/tex]

Solving this for ''x'' :

[tex]3x=2x+20\\3x-2x=20\\x=20[/tex]

The value of x that makes 3x° congruent to 2x+20° (that makes the alternate interior angles congruents) is x = 20

Answer:

20

Step-by-step explanation:

Theorem:

If two lines are cut by a transversal such that alternate interior angles are congruent, then the lines are parallel.

Lines m and n are cut by a transversal.

Angles 3x and 2x + 20 are alternate interior angles.

For lines m and n to be parallel, angles 3x and 2x + 20 must be congruent, so their measures must be equal.

3x = 2x + 20

x = 20

Answer: 20

2x^2-x-91=0

The length of the photograph is 13 cm and the width is 7 cm.

What is a rectangle?

A rectangle is a quadrilateral having the four sides and the sum of the angles is 180 in the rectangle the opposite two sides are equal and parallel and the two sides are at 90-degree angles.

Given that:-

The length of a photograph is 1 cm less than twice the widthThe area is 91 cm²

The length and the width will be calculated as:-

let the width = x

length = 2x  -  1

91  =  x  (  2x  -  1  )  =  2x² - x

2x² -  x  -  91  =   0

=  ( 2x  +  13  )  (  x   -  7 )

x  =  - 13  /   2

x  = 7 cm

Length will be  = 2x  -  1 =  2  x  7  -  1  =  13 cm

Therefore the length of the photograph is 13 cm and the width is 7 cm.

d.

Answers

Both plans will work for achieving the goal

Answer:

The correct option is C) Both plans will work for achieving the goal.

Step-by-step explanation:

Consider the provided information.

Plan A: Save $450 over the next 8 weeks by working 9 hours per week at $7.20 per hour.

For next 8 weeks by working 9 hours per week at $7.20 per hour, you will earn:

[tex]8 \times 9 \times 7.20 = 518.40[/tex]

We need to save $450 which is less than $518.40. Thus, plan A will work.

Plan B: Save $450 over the next 6 weeks by working 15 hours per week at $6.50 per hour.

For next 6 weeks by working 15 hours per week at $6.50 per hour, you will earn:

[tex]6 \times 15 \times 6.50 = $585.00[/tex]

We need to save $450 which is less than $585.00. Thus, plan B will work.

Hence, the correct option is C) Both plans will work for achieving the goal.

The cost of a classified ad is based on a daily rate plus a flat service fee. One day cost $3.50 and four days cost $800 write and solve a linear equation to find the cost of a 7-day ad.

Answers

x= 11

hope this helped :)


The linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00

The cost of a 7-day ad is $12.50.

Let, the daily rate is "d" dollars and the flat service fee is "f" dollars.

We are given two pieces of information:

One day costs $3.50.

Four days cost $8.00.

Using this information, we can set up two equations:

For one day: d + f = $3.50

For four days: 4d + f = $8.00

Now, we need to solve this system of linear equations to find the values of "d" and "f."

Subtract Equation 1 from Equation 2 to eliminate "f":

(4d + f) - (d + f) = $8.00 - $3.50

3d = $4.50

Now, divide both sides by 3 to solve for "d":

d = $4.50 / 3

d = $1.50

Now that we have the value of "d," we can find the value of "f" by substituting "d" into Equation 1:

d + f = $3.50

$1.50 + f = $3.50

Now, subtract $1.50 from both sides to solve for "f":

f = $3.50 - $1.50

f = $2.00

So, the daily rate (d) is $1.50, and the flat service fee (f) is $2.00.

We get, a linear equation that gives the cost in dollars, y, in terms of the number of days the ad appears, x is: y = $1.50x + $2.00

Now, to find the cost of a 7-day ad, we can use the daily rate and multiply it by the number of days (7):

Cost of a 7-day ad = 7 * $1.50 + $2.00

Cost of a 7-day ad = $10.50+ $2.00 = $12.50

The cost of a 7-day ad is $12.50.
