B. f(-5) = -70

Step-by-step explanation:

f(-5)= 10(-5) - 20

f(-5) = -50 - 20

f(-5) = -70

Answer:

f(-5) = -70

Step-by-step explanation:

f(-5) = 10(-5)-20

Answer:

Its 2 x radius

Step-by-step explanation:

Answer:

Twice the radius length.

Step-by-step explanation:

Generally, the diameter is the length of a line that extends from one point on a circle to another point on a circle as long as that line passes through the center of the circle. Essentially, a diameter, in short, is twice the length of the radius of a circle.

Answer:

Lina should make $471.75 a month.

Step-by-step explanation:

If Lina makes $9.25 an hour and she works for 15 hours a week then you multiply those two numbers together. The resulting number is $555. Then you'll multiply that by .15 to find 15% of that number which is 83.25. After, you'll subtract that from $555, which gives you $471.75.

Answer:

The weight of dogs x = 38pounds

Step-by-step explanation:

Step(i):-

Given that the mean weight of a group of dogs

       μ = 38 pounds

Let 'x' be the weight of dogs

Let 'x' be the random variable in normal distribution

Given that z-score is zero

Step(ii):-

we know that the z-score

                   [tex]Z = \frac{x-mean}{S.D}[/tex]

            ⇒  [tex]0 = \frac{x-38}{S.D}[/tex]

            ⇒ 0 = x-38

           ⇒  x-38 = 0

          ⇒   x =38

Final answer:-

The weight of dogs x = 38pounds

Answer:

2%

Step-by-step explanation:

To solve this problem, a proportion would be best! We can set up the first fraction with the two numbers given to us. We'll use t to represent tax, and w to represent the whole. The first fraction will look something like this:

[tex]\frac{9.80t}{490w}[/tex]

Next, we'll set up our second fraction using knowledge of percents. Every percent is a part of 100%, so we can use 100 as our percent to represent the whole. Since we are solving for the percent that is out of 100, we'll use x to represent it. The final proportion should look like this:

[tex]\frac{9.80t}{490w} = \frac{x}{100w}[/tex]

To solve, we just need to cross-multiply and divide! First, multiply 9.80 by 100 to get 980. Finally, divide 980 by 490 to get a final answer of 2%. The sales tax rate is 2%. The final calculations are as follows:

9.80 X 100 = 980

980 / 490 = 2 or 2%

Answer:

8 Seconds

Step-by-step explanation:

Since Jimmy runs 8 meters per second, we can multiply 8x8 to find where he will be after 8 seconds.

8x8 = 64

Since Jimmy's little brother runs 3 meters per second, we can multiply 3x8 to find where he will be after 8 seconds.

3x8 = 24

But, remember, Jimmy's little brother had a 40 meter head start. So we have to add 40 to his total.

24+40 = 64

Since Jimmy and his little brother's totals are both the same, Jimmy will catch up to his little brother after 8 seconds.

Answer:

125°

Step-by-step explanation:

By exterior angle theorem:

(3x - 70)° = 60° + x°

(3x - 70)° - x°= 60°

(3x - 70 - x)° = 60°

(2x - 70)° = 60°

2x - 70 = 60

2x = 60 + 70

2x = 130

x = 130/2

x = 65

(3x - 70)° = (3*65 - 70)° = (195 - 70)° = 125°

[tex] m\angle LKM = 125\degree [/tex]

Answer:

Divide by 3 on both sides.

Step-by-step explanation:

Original Expression: 3(x+2) = 12

Divide by 3 on both sides: x+2 = 4

Subtract 2 from both sides: x=2

b. 8 9/12 - 5 10/12

    7 21/12 - 5 10/12= 2 11/12

A: 5 1/2 - 1 1/3.

Answer: 25/6.

in mix fraction ot would be, 4 1/6

and in decimal from it will be, 4.166667.

B: 8 3/4 - 5 5/6.

Answer: 35/12.

In mix fraction it will be, 2 11/12.

and in decimal from it would be, 2.916667.

Answer:

86 or 32, depending on the correctness of the syntax

Step-by-step explanation:

We use PEMDAS:

Parentheses: 4(2)5 2-6/(-3)

Exponents: I'm assuming that all the syntax is correct (so no exponents).

Multiplication and Division: 40*2+6 = 80 + 6

Addition and Subtraction: 86

If you copy+pasted this expression, then the original equation would have been: (4(8 − 6)^5)/(2 − 6 ÷ (−3)). We can use PEMDAS:

Parentheses: (4(2)^5)/(2 - 6 ÷ (−3))

We now have the following fraction: 128/4

That simplifies to 32
