Answer:
In mathematics, a ratio indicates how many times one number contains another. For example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to six. Similarly, the ratio of lemons to oranges is 6∶8 and the ratio of oranges to the total amount of fruit is 8∶14.

Draw a line with a slope of -1/2 going through the point (4,5) already graphed for you. At what point does this line cross the y-axis?
Answer: What is the slope of this line? It's the 'm' term in y=mx+b. In this example, m=1. Therefore the slope of the line is 1, or said another way, the line goes "up" one unit every time it goes "over" one unit.
What is the y-intercept of the line? That's the 'b' term, so it's also 1. That means that when x is 0, y=1. Go ahead and plug x=0 into that equation to verify for yourself.
Step-by-step explanation:
Answer: 7
Equation: y= -1/2x + 7
Step-by-step explanation:
A slope of -1/2 means every x-value you go up by, the y-value goes down by 1/2.
To find an y-intercept you have to go back 4 x-values. So then you need to go up four 1/2 y-values. (simply 2 y-values).

The population of a city increases by 3.1% per year. If this year's population is 119,000, what will next year's population be, to the nearest individual?
Answer:
the next year population is 122,689
Step-by-step explanation:
The computation of the next year population is as follows:
= This year population × increase percentage
= 119,000 × (1 + 0.031)
= 119,000 × 1.031
= 122,689
Hence, the next year population is 122,689
The above formula is applied so that the correct value of the population could come

A=27 cm
A=
15 cm
A=45 cm2
A=
115 cm
A=27 cm
A = 45 cm
Answer:
The surface area is 174 cm^2
Step-by-step explanation:
Since we have the area of each of the faces, to get the total area, we will need to add up the areas of all these faces
Thus, we have that;
A = 45 + 27 + 45 + 15 + 15 + 27
A = 174 cm^2

Which type of graph is best suited for graphing the cost of a computer versus its speed?
Please help ASAP!!
Answer:
A: Line graph
Step-by-step explanation:
A pie chart is just percentages, so that wouldn't work. A box and whisker plot is for a number line, so that wouldn't work. A stem and leaf plot is for representing quantitative data in a graphical format, so that wouldn't work. The only logical choice is a line graph, since y could be the cost, and x could be the speed.

A snowboarder leaves an 8-foot tall ramp with an upward velocity of 28 feet per second. The function h =− 16t 8t gives the height h (in 2 + 2 + 8 feet) of the snowboarder after t seconds. When does the snowboarder hit the ground?
Answer:
2 seconds
Step-by-step explanation:
Given that:
h = -16t² + 28t + 8
Using quadratic formula:
[tex]\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
where;
a = -16
b = +28
c = +8
[tex]= \dfrac{-(28) \pm \sqrt{(28)^2 - 4(-16)(8)}}{2(-16)}[/tex]
[tex]= \dfrac{-(28) \pm \sqrt{784+512}} {-32}[/tex]
[tex]= \dfrac{-(28) + \sqrt{784+512}} {-32} \ \ OR \ \ = \dfrac{-(28) - \sqrt{784+512}} {-32}[/tex]
[tex]=- \dfrac{1}{4} \ \ OR \ \ 2[/tex]
Since we are considering the positive value; Then it will take the snowboarder 2 seconds before it hits the ground.

Instructions: Find the measurement of the diagonal indicated in the following parallelogram.
Help!!
Answer:
VX = 24
Step-by-step explanation:
Given :
VJ = 12 units
To find :
VX = ?
Solution:
Since, diagonal of a parallelogram bisect each other.
By this property,
m(VX) = 2[(VJ)]
m(VX) = 2(12)
= 24 units
Therefore, measure of the diagonal (VX) of the given parallelogram is 24 units.

Will give brainliest to first right answer. Before a sale an items price was $28.00 then after being discounted the price was $14.60. What was the discount for the item? with a exact fraction
Answer:
The discount was [tex]47\frac{6}{7}[/tex]%
Step-by-step explanation:
In order to find out the discount will have to do the following.
First find out what part of the origin price was taken of, so we create a fraction with the denominator being the original price and the numerator being the difference between the original price and the discount price. So we do.....
[tex]\frac{28.00-14.60}{28.00} = \frac{2800 - 1460}{2800} = \frac{1340}{2800} = \frac{67}{140}[/tex]
Now we have to find a fraction with the same value but with the denominator being a 100, so we do.....
[tex]\frac{67 / 1.4}{140/1.4}= \frac{47\frac{6}{7} }{100}[/tex]
From this we know that the the discount in percentages will be equal to [tex]47\frac{6}{7}[/tex]%
Answer:
52.1428571429
Step-by-step explanation:
14.60 × 100 = 1460
1460 ÷ 28 = 52.1428571429
