Answer:

a=-12

b=15

c=12

d=-12

Step-by-step explanation:

3(-4)=a

b(-3)=12

c=12

d(24)=12

3(-4)=a

-12=a

a=-12

b(-3)=12

-3b=12

b=12+3

b=15

c= 12

d(24)=12

24d=12

d=12-24

d=-12

Answer:

The number is 1.

Step-by-step explanation:

The number is x.

2(x + 3) = 8

2x + 6 = 8

2x + 6 - 6 = 8 - 6

2x = 8 - 6

2x = 2

2x ÷ 2 = 2 ÷ 2

x = 1

Use mean and standard deviation to fit a data set to a normal distribution when appropriate; estimate population percentages using tools Use the mean and standard deviation of a data set to fit it to a normal distribution and to estimate population percentages. Recognize that there are data sets for which such a procedure is not appropriate.

Answer:

-16

Step-by-step explanation:

If you look at the sequence, you'll notice that each number is two less than the number preceding it

-8 is 2 less than -6

-10 is 2 less than -8

And so on.

-16 is two less than -14, so it is the next number in the sequence.

The percent error of Ryan's measured area is 0.04%.

To calculate the percent error of Ryan's measured area, you need to subtract his measurement from the actual value and divide that by the actual value, and then multiply by 100 to express the result as a percentage.

First, find the difference between the actual value and Ryan's measurement: 94 feet - 93 feet = 1 foot for the length, and 50 feet - 48 feet = 2 feet for the width.

Then, multiply these values to find the difference in the area: 1 foot × 2 feet = 2 square feet.

Then, divide the difference in the area by the actual area and multiply by 100 to express the result as a percentage:

(2 square feet / (94 feet × 50 feet)) × 100 = 0.04255%.

Rounded to the nearest hundred, the percent error is 0.04%.

#SPJ2

Answer:

$199.31

Step-by-step explanation:

To find the answer, you have to do 190 x 4.9%, which is $9.31. You can also do 190 x 4 9/10, which you need to make the 4 9/10 an improper fraction, which is 49/10. 190 x 49/10 is 9.31.   190 + 9.31 is the answer ($199.31)

Step-by-step explanation:

sin(-240)°.

=cos(270-240)°

=cos 30°

=√3/2

cos(-240°)

=sin(270°-240°)

=sin30°

=0.5

tan(240°)

=tan(270°-240°)

=tan30°

=1/√3

Answer: 7/8

Step-by-step explanation:

To find the equivalent expression of a fraction, we can either multiply numerator and denominator by same variable or same number, or we can divide both numerator and denominator by same number or same variable .

So if we multiply both numerator and denominator by 2, we will get

[tex]\frac{7*2}{8*2} = \frac{14}{16}[/tex]

Answer:

sorry 98928

Step-by-step explanation:

Answer:

B. 10.6

Step-by-step explanation:

(x + 15)*15 = (20 + 12)*12 => interacting secants theorem

15x + 225 = (32)*12

15x + 225 = 384

Subtract both sides by 225

15x = 384 - 225

15x = 159

Divide both sides by 15

x = 159/15

x = 10.6

Answer:

[tex]Q = \frac{k}{14}[/tex]

Step-by-step explanation:

Given

k and 14

Required

Determine the quotient

Quotient implies that we divide k by 14.

So, the quotient (Q) of k and 14 is:

[tex]Q = \frac{k}{14}[/tex]

Answer:

A rectangle is a parallelogram with d. four congruent angles

Step-by-step explanation:

A rectangle has four right angles meaning they are congruent.

Answer:

Hi. I'm pretty sure you are supposed to use a compass (that's what I had to use for this math work). So basically what you have to do is for the dividing it in four one first divide it into two and divide those new parts in to four and then you have four equal parts, using a compass and/or straightedge works best. For dividing the segments into three parts measure it maybe with a ruler if you have one and mark the points where it can be equally divided.

Step-by-step explanation:

Hope you understand that :) I don't know how to show you on here sorry :(

GOOD LUCK!

Answer:

y=6/7x+11/7

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-1-5)/(-3-4)

m=-6/-7

m=6/7

y-y1=m(x-x1)

y-5=6/7(x-4)

y=6/7x-24/7+5

y=6/7x-24/7+35/7

y=6/7x+11/7
