Answer:

5/36

Step-by-step explanation:

1 x 5= 5

and 9 x 4=36

which makes 5/36

The solution to the product of the fractions is 5/36

From the question, we have the following parameters that can be used in our computation:

1/9 x 5/4

Express 1/9 as 1/9

So, we have

1/9 x 5/4 = 1/9 x 5/4

Evaluate the products of 1 and 5

So, we have

1/9 x 5/4 = 5/9 x 1/4

Evaluate the products of 9 and 4

So, we have

1/9 x 5/4 = 5/36

Hence, the solution is 5/36

Answer:

C. 128⁰

Step-by-step explanation:

12+40 = 32

32+128=180

Given:

Endpoints of segment AB are A(- 18, 5) and B(- 4, 5).

Point Z is located exactly 1/8 of the distance from A to B.

To find:

The value of the x-coordinate of point Z.

Solution:

Point Z is located exactly 1/8 of the distance from A to B.

AZ:AB=1:8

AZ:ZB = AZ:(AB-AZ)= 1:(8-1) = 1:7

It means point Z divided segment AB in 1:7.

Using section formula, the x coordinate of point Z is

[tex]x-coordinate=\dfrac{mx_2+nx_1}{m+n}[/tex]

[tex]x-coordinate=\dfrac{1(-4)+7(-18)}{1+7}[/tex]

[tex]x-coordinate=\dfrac{-4-126}{8}[/tex]

[tex]x-coordinate=\dfrac{-130}{8}[/tex]

[tex]x-coordinate=-16.25[/tex]

Therefore, the required x-coordinate of point Z is -16.25.

Answer:

No

Step-by-step explanation:

Plug in 7.5 as t into the equation, and solve:

p = -10t + 115

p = -10(7.5) + 115

p = -75 + 115

p = 40

Answer:

Necklace cost $144 and bracelet cost $48

Step-by-step explanation:

call x is the price of necklace, y is the price of bracelet

because necklace cost 3 time as much as the bracelet

=> 3x = y

A necklace and a bracelet cost $192

=> x + y = 192

=>set of equations

3x = y and x+y = 192

x= 3y and 3y + y = 192

=> y = 48 and x = 3 . 48 = 144

Answer:

The correct statements are: B and D.

Step-by-step explanation:

Standard deviation is one of the measure of dispersion or spread of a dataset from the average value of the dataset. The standard deviation measures the variability of the distribution of values.

The higher the spread or variability in the data set, the greater is the standard deviation value and thus greater will be the magnitude of the deviance of the value from their average.

Then the standard deviation (S.D.) is given by,

[tex]S.D.=\sqrt{\frac{1}{n-1}\sum\limits^{n}_{i=1} {(x_{i}-\bar x)^{2} }}[/tex]

The correct statements are:

B. It is a measure of variability.

D. It is calculated using the mean.

Answer:

a:b = 3:5.

Step-by-step explanation:

a + 0.25a = b - 0.25b

1.25a = 0.75b       Divide both sides by b:

1.25a / b = 0.75  Now divide both sides by 1.25

a/b = 0.75/1.25

a/b= 3/5.

Answer:

The expression is equal to 76.

8^2 becomes 64, and 6(14 - 12) becomes 6(2), which is 12. Add 64 and 12 and you get a sum of 76.

Answer:

I believe the answer is 76

Step-by-step explanation:

Equation: 8^2 + 6 (14 – 12)

First evaluate the power: 8^2= 64

Second solve in the parentheses: (14-12) = (2)

Third solve the multiplication: 6 * 2 = 12

Finally add: 64 + 12 = 76

Answer:

Simplifying

8x + -3 = 5(2x + 1)

Reorder the terms:

-3 + 8x = 5(2x + 1)

Reorder the terms:

-3 + 8x = 5(1 + 2x)

-3 + 8x = (1 * 5 + 2x * 5)

-3 + 8x = (5 + 10x)

Solving

-3 + 8x = 5 + 10x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-10x' to each side of the equation.

-3 + 8x + -10x = 5 + 10x + -10x

Combine like terms: 8x + -10x = -2x

-3 + -2x = 5 + 10x + -10x

Combine like terms: 10x + -10x = 0

-3 + -2x = 5 + 0

-3 + -2x = 5

Add '3' to each side of the equation.

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

Combine like terms: -3 + 3 = 0

0 + -2x = 5 + 3

-2x = 5 + 3

Combine like terms: 5 + 3 = 8

-2x = 8

Divide each side by '-2'.

x = -4

Answer: x = 21

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8x−2=6+10(x−5)

8x+−2=6+(10)(x)+(10)(−5)(Distribute)

8x+−2=6+10x+−50

8x−2=(10x)+(6+−50)(Combine Like Terms)

8x−2=10x+−44

8x−2=10x−44

Step 2: Subtract 10x from both sides.

8x−2−10x=10x−44−10x

−2x−2=−44

Step 3: Add 2 to both sides.

−2x−2+2=−44+2

−2x=−42

Step 4: Divide both sides by -2.

−2x / -2 = -42 / -2

x=21

Answer:

x = 21

Step-by-step explanation:

8x - 2 = 6 + 10(x - 5)

Step 1: Distribute the right side of the equation ("6 + 10(x - 5)") so it'll be easier to find x.

8x - 2 = 6 + 10x - 50

8x - 2 = 10x - 44

Step 2: Subtract 8x from both sides

8x - 2 = 10x - 44

-8x         -8x

-2 = 2x - 44

Step 3: Add 44 to both sides to get 2x alone.

-2 = 2x - 44

+44       +44

42 = 2x

Step 4: Divide both sides by 2 to get x alone

42 = 2x

2      2

x = 21

Answer:

C

Step-by-step explanation:

So, we want to find the equation of the line graphed.

To do so, let's first find the slope. Let's pick two points from the graph. I'm going to use (-2,2) and (0,-1).

The formula for slope is:

[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Let's let (-2, 2) be (x₁, y₁) and let's let (0,-1) be (x₂, y₂). So, substitute:

[tex]m=\frac{-1-2}{0-(-2)}[/tex]

Subtract:

[tex]m=\frac{-3}{2}[/tex]

So, our slope is -3/2.

Now, we can use the point-slope form, which is:

[tex]y-y_1=m(x-x_1)[/tex]

Where m is the slope and (x₁, y₁) is any point on the graph.

Since our answer choices are using the values 2 and 4, this means we can use the point (2,-4).

So, (2,-4) is our (x₁, y₁).

Also, our m is -3/2. So, substitute these into the point-slope form:

[tex]y-(-4)=-\frac{3}{2}(x-2)[/tex]

Simplify:

[tex]y+4=-\frac{3}{2}(x-2)[/tex]

Therefore, our answer is C.

And we're done!
