Answer 2

Answer:

Step-by-step explanation:

when x is greater than AND equal to -2

the numberline will show a closed circle on -2 and a line to the right (because greater than means positive and all numbers to the right increase)

Please help I’m struggling on this topic

Answers

answer: x=36
explanation: in the corner of (2x+18)°, it would be 90° as it is a right angle, 90-18=72 72/2=36, putting it into the equation 2(36)+18=90°. for (3x+6), putting 36 as x 3(36)+6=114° since every 3-sided triangle and a line with another line crossing through has angles that add up to 120°, if you add up 90 and 24 you get 114°, 120-114=6. if you add 6 to the 114° from the (3x+6)° equation you also get 120°, therefore x=36

Is this a function please help I’m failing

Answers

Answer:

Yes

Step-by-step explanation:

The relation is a function. For a relation to be a function there must be a unique x value for each y value. So this means x's can not repeat, and in this relation, the x-values never repeat. Therefore this is a function.

use the elimination method to solve the system of equations. choose the correct ordered pair. 7x+3y=30 -2x+3y=3

Answers

Answer:

x = 3, y = 3

Step-by-step explanation:

Elimination method to find x:

(7x + 3y = 30) * -1 ===> -7x - 3y = -30

-2x + 3y = 3

add two equations to eliminate y ______________

-9x = -27 ===> x = 3

substitution to find y:

-2x + 3y = 3

-2(3) + 3y = 3

-6 + 3y = 3

3y = 9

y = 3

Elimination method to find y:

(7x + 3y = 30) * 2 ===> 14x + 6y = 60

(-2x + 3y = 3) * 7 ===> -14x + 21y = 21

add two equations to eliminate x ______________

27y = 81 ===> y = 3

the scale on a blueprint for a new apartment is 1 in equals 4 feet if the length of the living room on the blueprint is 6 in, what is going to be the actual length of the living room?

Answers

Answer:

The actual length of the living room is 24 feet.

Step-by-step explanation:

Scaling

The scaling on a blueprint for an apartment is:

1 inch = 4 feet

This means every 1 inch measured on the blueprint corresponds to 4 feet on the real length of the apartment.

We know the length of the living room in the blueprint is 6 inches, thus the real dimension of the living rooms is:

6 * 4 = 24 feet

The actual length of the living room is 24 feet.

If a is 63% of x and c is of x, which of the following is

the closest equivalent of the ratio of a to c?
3

Answers

Answer:

The closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

Step-by-step explanation:

Given

a is 63% of x

i.e.

a=0.63x

c is 3/8 of x.

i.e.

c=3/8x

Hence,

[tex]\frac{a}{c}=\frac{0.63x}{\frac{3}{8}x}[/tex]

[tex]\frac{a}{c}=1.680\:[/tex]

Thus, the closet equivalent of the ratio of 'a' to 'c' is:

[tex]\frac{a}{c}=1.680\:[/tex]

Jane has saved 600 dollars in a college fund. She added money to the account over the next year and at the end of the year the account had 890 dollars. Write an equation to represent the amount she saved over the year.

Step-by-step explanation:

The equation would be 890-600=290 because if you subtract the base amount from the final savings it would give you how much she saved altogether.

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x because each x has a different unknown coefficient. Victoria believes there is a solution, and shows Jalil her work

Answers

Answer:

[tex]x=\frac{d+c}{a-b}[/tex]

Step-by-step explanation:

The equation is:

a x - c = b x + d

so we subtract b x from both sides to group the terms that contain x on the left:

a x - b x - c = d

add c to both sides to isolate the terms in x on the left:

a x - b x = d + c

extract "x" as common factor on the left:

x (a - b) = d + c

divide both sides by the quantity (a - b) to isolate the "x":

x = (d + c) / (a - b)

or: [tex]x=\frac{d+c}{a-b}[/tex]

what is 903 minus 538

Answers

Answer: Your answer is 365

Step-by-step explanation: Hoped this helped you. And have a wonderful day!!!

The final result of 903 - 538 is 365.

To subtract 538 from 903, you perform the following calculation:

903 - 538 = 365

To explain the process, you start with the number 903 (minuend) and subtract 538 (subtrahend) from it.

1. Begin with the units place: 3 - 8. Since 8 is greater than 3, you borrow 1 from the tens place. The units place becomes 3 + 10 (borrowed) - 8 = 5.

2. Move to the tens place: 0 (in 903) - 3 (borrowed) - 3 (from 538) = -6.

3. Lastly, the hundreds place: 9 - 5 (from 538) = 4.

Nancy Boone’s new automobile had an MSRP of $27,853.00. The dealer prep charge was $278.50 and the title fee was $25.00. Options totaled $2,375.50. Find the sales tax rate, to nearest hundredth percent, if the total cost was $32,591.22 and the sales tax applied to everything but the title fee.

Answers

Answer:

The sales tax included in the sale of the car is 15.76%.

Step-by-step explanation:

Given that the MSRP of the car bought by Nancy Boone is $ 27,853, and the total cost of the car was $ 32,591.22, including sales tax, plus a dealer prep charge of $ 278.50 and a title fee of $ 25, to find out the percentage of sales tax ( which does not include the title fee) it is necessary to perform the following calculation:

32,591.22 - 25 = 32,566.22

27,853 + 278.5 = 100

32,566.22 = X

28,131.5 = 100

32,566.22 = X

(32,566.22 x 100) / 28,131.5 = X

3,256,622 / 28,131.5 = X

115.76 = X

115.76 - 100 = 15.76

Thus, the sales tax included in the sale of the car is 15.76%.

Except middle school grades

Answer:

C. middle school grades

Step-by-step explanation:

Colleges want to see if students challenged themselves by taking rigorous courses, and they also want to know what kind of grades students were able to maintain. They also like to take into account the scores you get on standardized tests because these tests can give a relatively accurate idea of a student's mastery of certain subjects. The only thing they don't pay attention to are the grades you earned in middle school. Since these grades aren't very recent, they don't serve as an accurate measure of a student's academic ability, which is why colleges prefer to look at the grades a student earns during their time in high school.

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign. How many social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2% (ME=0.02)?

Answers

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

Step(i):-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that [tex]\sqrt{p(1-p}\leq \frac{1}{2}[/tex]

Step(ii):-

Given margin of error = 2 % =0.02

The margin of error is determined by

[tex]M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }[/tex]

[tex]0.02 = \frac{\frac{1}{2} }{\sqrt{n} }[/tex]

[tex]\sqrt{n} =\frac{1}{2 X0.02}[/tex]

√n = 25

squaring on both sides, we get

n = 625

Zeke has swim club every 2 days and robotics Club every 8 days.
This month, he has swim club on the 2nd day of the month and robotics club on the 8th day of the month.
Zeke says that the first time he will have both clubs on the same day is the 16th day of the month because the LCM of 2 and 8 is 16.

Answers

Answer: No. Zeke found the LCM to be the product of two and eight but because eight is a multiple of two the LCM is eight so the first day he will have both clubs is the 8th day of the month

Step-by-step explanation:

all you have to do is fine the least common multiple of 2 and 8 which is eight so obviously zeke is incorrect because they said the least common multiple was 16 and it is not. zeke multiplied 2 and 8 which is not what you’re supposed to do to get the lcm.
