On the diagram i need to fond the following measures of angles. Please help quickly!

Answer:

C

Step-by-step explanation:

Usually rate is determined as a distance over time, where the time is a unit. In other words, we have "1" of the time (for example, 1 hour, 1 second, 1 gallon, etc).

Look at each answer choice:

A: doing 45 crunches in 1 minute

This is definitely a rate because the time (1 minute) is a unit.

B: paying $3.15 for 1 gallon of gas

Again, this is considered a rate because you're paying $3.15 per gallon.

C: folding 6 loads of laundry in 3 days

We can see this isn't a rate because the time is 3 days, not 1. So C is the answer.

D: walking 4 miles in 1 hour

This is a rate because our time is 1 hour.

The answer is C.

Answer:

C.folding 6 loads of laundry in 3 days

Step-by-step explanation:

folding 6 loads of laundry in 3 days means, 6/3 = 2 loads of laundry per day.

Rate is 2 per day

Answer:

Mean - 7

Median - 7.5

mode - 9

range - 6

The answer is the top one to the right

The graph that represents the function g(x) = 2(0.5)ˣ -1 is given.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given expression,

g(x) = 2(0.5)ˣ -1

To draw the graph take x = 0, 1,2, -1 , -2 and so on .

And draw these numbers in the graph.

Take x=0

g(0) = 1

the point is (0,1)

And now , take x = 1

g(1) = 0

the point is (1,0)

Take x =-1

g(-1) = 3

The point is (-1,3)

Therefore, the graph is given in the image.

2520 in³

Step-by-step explanation:

The volume of a prism is calculated as

V = Ah ( A is the area of the base and h the height )

A = [tex]\frac{1}{2}[/tex] bh( b is the base and h the height ), thus

A = [tex]\frac{1}{2}[/tex] × 14 × 18 = 7 × 18 = 126 in²

V = 126 × 20 = 2520 in³

Answer:

x = 0

Step-by-step explanation:

The equation of a line is shown by using the formula y = mx+b

But, in special cases like this one, where the line is completely vertical then we use the same formula but we just adjust it.

When a line is completely straight up and down the equation is x = #

Since the line is on the y-axis (or has a x value of zero) the equation is x = 0.

There is no y in this equation because the line is hitting all values of y (which means y is ∞) with only 1 value of x. (As opposed to most equations where one or multiple values of y with one value of x or vise-versa.)

Answer: A

Step-by-step explanation:

The correct statement about the volumes of the two cylinders is,

⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

In the drawing,

s > t

Where, 's' is radius of left hand side cylinder and 't' is radius of right hand side cylinder.

We know that;

Volume of cylinder = πr²h

Hence, Volume is directly proportional to radius.

Larger the radius gives large Volume.

Hence, WE get;

The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

Thus, The correct statement about the volumes of the two cylinders is,

⇒ The volume of the right-hand cylinder is less than the volume of the left-hand cylinder.

Answer:

500 mg Carbon Monoxide

1100 mg Carbon Dioxide

Step-by-step explanation:

Weight of total sample = 1600 mg

Percentage of Carbon in Carbon Monoxide = 43%

Percentage of Carbon in Carbon Dioxide = 27%

Percentage of carbon in Mixture = 32%

Let amount of Carbon Monoxide = [tex]x[/tex] mg

Amount of Carbon Dioxide in mixture = (1600-[tex]x[/tex]) mg

Amount of carbon in [tex]x[/tex] mg of Carbon Monoxide =

[tex]x \times 43\%\\\Rightarrow x \times \frac{43}{100} ...... (1)[/tex]

Amount of carbon in (1600-[tex]x[/tex]) mg of Carbon Monoxide =

[tex](1600-x) \times 27\%\\\Rightarrow (1600-x) \times \frac{27}{100}......(2)[/tex]

We know that the sample of 1600 mg contains carbon because of Carbon Monoxide and Carbon Dioxide present in it.

Adding (1) and (2) and equating to 32% of 1600 mg:

[tex]x \times \dfrac{43}{100} + (1600-x) \times \dfrac{27}{100} = 1600 \times \dfrac{32}{100}\\\Rightarrow x \times (43-27) = 1600 \times (32-27)\\\Rightarrow 16x = 1600 \times 5\\\Rightarrow x =500[/tex]

Amount of Carbon Monoxide in sample,[tex]x[/tex] = 500 mg

Amount of Carbon Dioxide in sample = (1600 - [tex]x[/tex]) = (1600 - 500) = 1100 mg

Hence, answer is

500 mg Carbon Monoxide

1100 mg Carbon Dioxide

Answer:

A.) y=3x-1

Step-by-step explanation:

Point-slope form can be shown using the equation: y = mx+b

In this case, m is slope, and b is the y-intercept.

Slope in this graph can be found by finding the rise over the run, or the number of blocks the line moves vertically over the number of blocks the line moves horizontally. The line moves at a rate of 3 blocks up for every 1 block to the right, or 3/1. That means that the slope is 3.

The y-intercept is wherever the line crosses the y-intercept, or wherever x equals 0. This happens at y = -1.

If you plug the slope (3) and the y-intercept (-1) into the equation y = mx+b, you get y = 3x-1.
