Answer:

5x + 10y + 5z

Step-by-step explanation:

Given the expression

[tex]\frac{1}{2}(10x+20y+10z)\\[/tex]

Expand the parenthesis using the distributive law;

[tex]\frac{1}{2}(10x)+ \frac{1}{2}(20y)+\frac{1}{2}(10z)\\= \frac{10x}{2} + \frac{20y}{2} + \frac{10z}{2}\\= 5x + 10y + 5z[/tex]

Hence the required solution is 5x + 10y + 5z

4 entries are  24   so one  entry is  24/4 = 6  

so 7 friends pay  6*7 = 42

Answer:

shading three boxes

Step-by-step explanation:

It is given that :

The body weight of an average adult = 60%

We have to show this by shading the square boxes shown.

There are 5 square boxes in total which makes up 100%.

So divide 100 by 5, we can 20% for each box.

So, 20% + 20% + 20%  will give us 60%

Therefore, shading three boxes will give us 60% which is the water percent in an average adult's body weight.

This is represented by the figure below.

Answer:

1 1/5

Step-by-step explanation:

To add fractions there are Three Simple Steps: Step 1: Make sure the bottom numbers (the denominators) are the same, Step 2: Add the numerators, put that answer over the denominator, Step 3: Simplify the fraction (if needed)

Answer:

5.6

Step-by-step explanation:

Answer:

2nd option

Step-by-step explanation:

Using the identities

tan²θ + 1 = sec²θ

cotθ = [tex]\frac{1}{tan0}[/tex]

Given

secθ = - [tex]\frac{37}{12}[/tex] , then

tan²θ + 1 = (- [tex]\frac{37}{12}[/tex] )² = [tex]\frac{1369}{144}[/tex] ( subtract 1 from both sides )

tan²θ = [tex]\frac{1225}{144}[/tex] ( take the square root of both sides )

Since [tex]\frac{\pi }{2}[/tex] < θ < π and tanθ < 0 , then

tanθ = - [tex]\frac{35}{12}[/tex]

Then

cotθ = [tex]\frac{1}{-\frac{35}{12} }[/tex] = - [tex]\frac{12}{35}[/tex]

Answer:

Step-by-step explanation:

Slope of line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,

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

From the graph attached,

Slope of the line passing through (-3, 0) and (0, 5) = [tex]\frac{5-0}{-3-0}[/tex]

                                                                                    = [tex]-\frac{5}{3}[/tex]

Line passing through a point (h, k) and slope 'm' will be,

y - h = m(x - k)

Since, line passing through (11, 0) is parallel to the line given in the graph,

Slope of the parallel line will be same as [tex]-\frac{5}{3}[/tex]

Equation of a line passing through (11, 0) and slope = [tex]-\frac{5}{3}[/tex]

y - 0 = [tex]-\frac{5}{3}(x-11)[/tex]

y = [tex]-\frac{5}{3}(x-11)[/tex]

Now satisfy this equation with the points given in the options,

Option (1)

For (1.67, -15.59),

-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]

-15.59 = -15.55

False.

Therefore, given point doesn't lie on the line.

Option (2)

For (-0.33, -13.59)

-13.59 = [tex]-\frac{5}{3}(-0.33-11)[/tex]

-13.59 = -18.88

False

Option (3)

For (0.67, -18.59),

-18.59 = [tex]-\frac{5}{3}(0.67-11)[/tex]

-18.59 = 17.22

False

Option (4)

For (1.67, -15.59)

-15.59 = [tex]-\frac{5}{3}(1.67-11)[/tex]

-15.59 = -15.55

False.

Therefore, none of the points given in the options are lying on the line.

Answer:

13 possible combinations

Step-by-step explanation:

There are 3 different types of pizza sizes and two different types of pans. There are 5 different toppings available which can be used in the pizza.

5C3 + 3C2 = 10 + 3

Total possible combinations = 13.

Answer:

Sin A = 5/13; tan C = 12/5

Step-by-step explanation:

Sin = opposite / hypotenuse. The opposite of A is 5, and the hypotenuse is 13, therefore Sin A = 5/13.

Tan = opposite / adjacent. The opposite of C is 12, and the adjacent is 5, so tan C = 12 / 5

Answer:

D

Step-by-step explanation:

You just distribute the negative sign.

Answer:

3.55-3.59

Step-by-step explanation:

to round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.

So numbers that would be rounded off to 3.6 have to have an hundredth value equal or greater than 5

they include

3.55

3.56

3.57

Answer:

68

Step-by-step explanation:

Find the scale Factor:

What do you do to 10 to make it 4?

Divide by 2.5 or Multiply by 0.4

Since, Scale factors are always written as multiplications, use x 0.4

Find the area of the smaller pentagon:

Value 1 x Scale Factor = Area of larger pentagon x 0.4 = 68.8 ≈ 68
