Answer:

x = [tex]\sqrt{21}[/tex]

Step-by-step explanation:

AC² = AB² + BC²

BC² = 3² + x² = 9 + x²

AB² = 7² + x² = 49 + x²

But AC² = (7 + 3)² = 100

∴ 100 = 49 + x² + 9 + x²

2x² + 58 = 100

x² = 50 - 29 = 21

x = [tex]\sqrt{21}[/tex]

Answer: the answer is the square root of 21.

Step-by-step explanation:

What I did was I just multiplied 7 times 3 and got 21 and that was the answer.

Step-by-step explanation: -7 is not included in the shaded part of the inequality

Answer:

Step-by-step explanation:

-2w-7.25<-3.25 add 7.25 to both sides

-2w< 4  divide by -2

w< -2

W has to be smaller than -2

The smaller than -2 is -7. So all the others are not.

Mean=13

Step-by-step explanation:

Mean = sum of number/ total number

Total number= 6

Number are . 11, 17, 13, 11, 5, 19

Mean=11+17+13+11+5+19/6

=76/6=12.66

Nearest tenth of 12.66=13

Answer:

Step-by-step explanation:

I don't know why the answers don't offer this an option. However, the side that shares both triangles must be congruent to itself and the other highlighted congruent parts are sides, not angles. Therefore by my calculations, the answer has to be SSS, but this isn't a choice.

Answer:

120%

Step-by-step explanation:

Answer:

Texas Loan & Credit will yield better interest earnings after Janice invested $1,000 for 2 years.

The interest earnings will be $120 as against Pecan & Cedar's $60.90.

Explanation:

Texas Loan & Credit:

Simple interest rate = 6%

Janice's Investment = $1,000

Interest earnings = $120 ($1,000 * 6% * 2)

Pecan & Cedar Savings Bank:

Compound interest rate = 3%

Janice's investment = $1,000

Interest earnings = $60.90 ($1,000 * 3%) + ($1,030 * 3%)

In the second year, the interest earnings of $30 are added to the principal to get a new compounded principal of $1,030 on which 3% is also applied.

Answer:

$31.00

Step-by-step explanation:

124 x 25 = 3100, 3100 divided by 100 = 31.00

Slope is 2

Step-by-step explanation:

To find slope

m=y2-y1

    ---------

    x2-x1

m=   20-8

m=2

Answer:

m=2

Step-by-step explanation:

Answer:

$11.36 (11 dollars and 36 cents).

Step-by-step explanation:

This scenario can be written as the linear equation: y = -$0.16x + $20 Where y is the remaining credit, and x is the minutes spend calling.

To find the remaining credit after 54 minutes,

substitute 54 for x and simplify.

So y = -$0.16(54) + $19.60 = -$8.64 + $20.00 =

$20.00 - $8.64 = $11.36.

_________________________

If you want to solve this problem from scratch, first find the constant rate of money by subtracting 30 minutes (time) over $15.20(total) by 46 minutes over $12.64(total).

Just subtract across, and simplify to get the rate, and then apply that rate between the missing total of 54 minutes and the total of $12.64 dollars for 46 minutes. This is because rate = change quantity/change in time. If that rate is constant as it is in this relationship where the quantity is the amount of anything that is dependent on something, in this case it's money.

So subtract (find the difference) to find the pattern of change between these values in respect to time.

15.20/ 30 - 12.64 / 46 = 2.56 / -16 = 1.28 / -8 = 0.64 / -4 = 0.32 / -2 = 0.16 / -1 = -0.16 [This is the rate decrease in money every minute of a call being made or decrease in remaining credit every minute ].

Now since we know the rate, we can solve the missing factor of the problem by multiplying the rate by the change in time to get the change in quantity.

So : 54 - 46 = 8. 8 × 0.16 = 1.28 [This is the change in quantity from 46 to 54 minutes of calling ].

Therefore, $12.64 [remaining credit from 46 minutes ] - $1.28 [the change of credit from 46 minutes to 54] = $11.36 [remaining credit from 54 minutes].

Also in general, Rate = dependent variable / independent variable.

Answer: $24.75

Step-by-step explanation: If you minus $27.50 by 10% percent you can get the answer.

Answer:

$25.00

Step-by-step explanation:

Net Amount (excluding tax) $25.00

Tax (10.0%) $2.50

Gross Amount (including tax) $27.50

in short 10% tax of $25.00 is $27.50.

Answer:

57

Step-by-step explanation:

23-(-34) = 57

(finge que el -(- es un plus)

Answer:

57

Step-by-step explanation:

if u subtract from a negative it is the same as adding a positive. So instead of 23 - (-34) you should do the equation 23 + 34 which equals 57.

Answer:

The answer is: y - (-4)= 5(x-3)

Point slope form is:

y-y1=m(x-x1)

m is your slope. They tell us the slope is 5. They also give you an ordered pair. Substitute this ordered pair into the point slope equation for the x1 and y1 values.

Answer:

3/4

Step-by-step explanation:

step 1) turn 0.75 into a fraction (0.75 = 75/100)

step 2) find the greatest common factor then divide it

75/100 ÷ 25/25 = 3/4

Answer:

The third one is the correct answer .

Because the x's don't have more than 1 y value .

All the other tables do, which makes those not a function, but since the third one has 1 x value for 1 y value, then it is a function.

Answer:

It's the second to the top one

Step-by-step explanation:

because the positive y numbers correspond to a negative x 2 and vice versa

First let's add 6x to both sides. We do this because the 6x is negative and by adding 6x to both sides, we are isolating the 11 and we are also making the 6x positive, which makes things easier later.

-6x + 11 = -7

+6x          +6x

11 = -7 + 6x

Now let's flip the equation to make it easier to read:

-7 + 6x = 11

And let's add 7 to both sides as we need to isolate the 6x. We are adding 7 because the 7 is negative.

6x = 18

And finally to get the value of x we divide both sides by 6:

x = 3

I hope this helped, and have a great night! :)

Answer:

  A)  44

Step-by-step explanation:

The sum of angle measures is 180°

  84 + (x+59) +(x +51) = 180

  2x +194 = 180 . . . simplify

  2x = -14 . . . . . . . . subtract 194

  x = -7 . . . . . . . . . . divide by 2

Angle A is ...

  x +51 = (-7) +51 = 44 . . . . degrees

∠A = 44°

Answer:

There are no solutions

Step-by-step explanation:

Every solution is going to equal 6 instead of the designated 12.

For example if x equals 26:

6 x 26 = 156 + 2 = 158

Y = 158

3 x 158 = 474

18 x 26 = 468

474 - 468 = 6
