Answer: 20

Step-by-step explanation:

*This is a supplementary Angle (adds up to 180 degrees)

5x+12+68=180

5x+80=180

*subtract 80 on both sides

5x=100

*divide both sides by 5

x=20

Answer:

130%

Step-by-step explanation:

Use the formula for percent change: difference = % * original price

To find the difference, you have to do 299 - 130, which is 169.

The original price is $130 because this is the price before it rose to $299.

Now, you have the equation 169 = % * 130.

We don’t know the percentage right? No, so we have to find the percentage by dividing 169 by 130, which gives you 1.3. Lastly turn 1.3 into a percentage by multiplying 1.3 by 100, and 1.3 as a percentage is 130%. So therefore, the percent increase is 130%.

130%

Step-by-step explanation:

Yesterday = $130.

Today = $299 .

((final price - initial price)/(initial price)) × 100%

= (($299 - $130)/$130) × 100%

= ($169/$130) × 100%

= $1,3 × 100%

= 1,3 × 100%

= 130%

Answer:

angle one is 90

angle two is 115

angle 3 is 65

Step-by-step explanation:

A line can be drawn by joining the plot of the two given points

Reason:

Given points on the line are (-5, 3) and (-1, -1)

The slope, m, of the line is given as follows

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Therefore, we have;

[tex]Slope, \, m =\dfrac{-1 - 3}{-1 - (-5)} = \dfrac{-4}{4} = -1[/tex]

The equation of the line in point and slope form is therefore;

y - 3 = -1·(x - (-5) = -x - 5

In slope and intercept form, we have;

y = -x - 5 + 3 = -x - 2

Step-by-step explanation:

613 and 623 are very close values.

multiplying by 12 or a division by 2 changes the starting value drastically.

so, this cannot be right.

and dividing 613 by 2 also makes it even smaller. but to get 623 we need to make it bigger.

so, therefore, even without actually calculating the numbers, the statement is proven false.

Answer:

173.5

Step-by-step explanation:

The answer is 173.5

To solve this type of equation we first have to find the unit rate, in this case, the unit rate is dollars every hour, in order to find this we have to divide 86 by 4 as shown below

[tex]86/4=21.5[/tex]

Therefore the unit rate is 21.5$ every hour so in order to find how much money she was paid after 9 hours we have to multiply 21.5 by 9, which is shown below

[tex]9x21.5=173.5[/tex]

Thus, that is how much money Lin will be paid after 9 hours of work.

Answer:

[tex]219456[/tex]

Step-by-step explanation:

It must end in [tex]0,2,4,6,8[/tex] (divisible by 2 rule) and the digits must sum to a multiple of 9(divisible by 9 rule).

The digit sum is [tex]2+A+9+4+5+B=20+A+B[/tex].

We want to make [tex]A[/tex] as low as possible because it's a higher digit than [tex]B[/tex].

If [tex]A[/tex] is as low as possible, we have that the sum is [tex]20+0+7=27[/tex]. Uh-oh. [tex]B[/tex] has to be even! So [tex]A=0[/tex] doesn't work.

If [tex]A=1[/tex], we have that the sum is [tex]20+1+6=27[/tex]. Yay!

So, the answer is [tex]\boxed{219456}[/tex]

Answer:

309 meters

Step-by-step explanation:

The scale is 3mm : 2m so you can set up two fractions and solve for x.

[tex]\frac{3mm}{2m} =\frac{x}{206m}[/tex]

since every two meters is 3 mm in the drawing, divide 206 by 2 and get 103

now, multiply 103 by 3 to get 309

309 mm in the drawing

Answer: 1/10squarerootY i think

Answer:

[tex] f(x)=8x^2+4\\ g(x)=\sqrt{2x^3}\\ f(g(x))=8((\sqrt{2x^3})^2)+4\\=16x^3+4\\=4(4x^3+1)[/tex]

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The functions are given below.

f(x) = 8x² + 4

g(x) = √(2x³)

The function f(g(x)) is calculated as,

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 8[√(2x³)]² + 4

f(g(x)) = 16x³ + 4

f(g(x)) = 4(4x³ + 1)

The function f(g(x)) will be f(g(x)) = 4(4x³ + 1) where 'x' is the number of hours.

Answer: 1/10 or 0.1

Step-by-step explanation:

    -(-7 - 4x) = -2(3x - 4)

      7 + 4x = -6x + 8

   * subtract 7 from both sides

            4x = -6x + 1

   * Add 6x to both sides

           10 x = 1

   * Divide both sides by 10

             x = 1/10  or 0.10

Answer:

2.58

Step-by-step explanation:

=======================================================

Work Shown:

Distance = rate*time

rate = distance/time

----------------

For Sarah, she runs 324 m in 61.3 seconds. Her speed is:

rate = distance/time

rate = (324 m)/(61.3 sec)

rate = (324/61.3) meters per second

rate = 5.28548 meters per second approximately

----------------

Repeat the same set of steps for Emily

rate = distance/time

rate = (324 m)/(60.4 sec)

rate = (324/60.4) meters per second

rate = 5.36423 meters per second approximately

----------------

The last thing to do is subtract the results we got

5.36423 - 5.28548 = 0.07875

This then rounds to 0.08 meters per second when rounding to two decimal places.
