Ryan has a toy car collection consisting of 160 toy cars he keeps on the wall and 340 he keeps in a display case. What percentage of Ryan's toy car collection does he keep on his wall?
Answer:
32%
Step-by-step explanation:
First find the whole, the total number of toy cars:
160 on the wall} + 340 \text{ in display case} = }{500} total toy cars}
160 on the wall+340 in display case=500 total toy cars
Method 1: Set up a proportion
Set up an equation of the form:
whole
part
= }{100}
100
percent
Assign the variable xx to the unknown value:x}=
x=
percent
The question asks what }percent of all the toy cars is 160
Substitute the known values with the numbers given in the problem, and the unknown value with xx:
\frac{\color{red}{160}}{\color{orange}{500}}=
500
160
={100}
100
x
Solve for xx:
100}{160}=
100⋅160=
{500}
500⋅x
Cross multiply
16000}{500}=
500
16000
=
{500x}{500}
500
500x
Divide both sides by 25
{32\%}=
32%={x}
x
Simplify
Method 2: Find percent directly
Find \(160\) out of \(500\) as a decimal:}
Find 160 out of 500 as a decimal:
{160} {500}}=
500
160

The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.
Calculation of the percentage:Since Ryan has a toy car collection consisting of 160 toy cars he keeps on the wall and 340 he keeps in a display case.
So here the percentage be like
[tex]= 160 / (160 + 340)[/tex]
= 32%
Hence, The percentage of Ryan's toy car collection does he keep on his wall should be considered as the 32%.

Answer:
y = - x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 2, 1) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-1}{0+2}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1
The line crosses the y- axis at (0, - 1 ) ⇒ b = - 1
y = - x - 1 ← equation of line
Answer:
y= - x -1
Step-by-step explanation:
ran it through Desmos
I can't find a way to expllain
it if i would put y= - 1 (becaues remember -1 is where the lines intersected with the y axis)
all there would be was a straight
line across -1 but since its goin down 1
you need the - x to give it a negative tilt

Points A, B, C, and D are vertices of a square. Point E is inside the square. Explain how to tell whether point E is closer to A, B, C, or D.
Answer:
To determine if a point E inside a square is closer to any of the vertices of the square we have to determine the length of the diagonals between the point E and the vertices of the square i.e. AE, BE, CE, DE
The diagonal can be determined by applying Pythagorean's theorem

Find (8.4×108) ÷ (1.2×103). Express your answer in scientific notation.
Answer: 7.33980582 x 10^0
Step-by-step explanation:
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. The sign of the exponent will depend on the direction you are moving the decimal.
The expression in scientific notation is 7 ×10^5
What is the basic arithmetic operations?The four basic mathematical operations are Addition, subtraction, multiplication, and division.
Given that the terms are;
(8.4×10^8) ÷ (1.2×10^3)
Step 1: Divide the numerical parts:
8.4 ÷ 1.2 = 7
Step 2: Subtract the exponents:
10^8 /10^3 = 10^5
Now Putting the numerical part and the exponent together, we get:
7 ×10^5
Hence, the result of the expression in scientific notation is; 7 ×10^5

Plz help I literally suck at math... btw this is 6th grade math (there is an image)
Answer:
y=7x
Step-by-step explanation:
one way to think of it is by taking a y value from the table like (for example) 42 so you would do something like 42 divided by x = 6, or u could just do 42 divided by 6 which gives u 7. u can check ur answer by plugging in an x value to the equation. so for example we can plug in 8 to y=7x which is basically 7x8 and 7x8 is 56 which is true to the table.

Ahmad run 5 kilometres. If he completed 15% of the race. How many kilometres is the race?
Answer:
x = 33.33 kilometers
Step-by-step explanation:
you could make use of the percent, base, and rate formula here. we know that 15% is the rate, 5 kilometers is the percent, therefore what we are looking for is our base.
[tex]\frac{percent}{base} =\frac{rate}{100}[/tex]
[tex]\frac{5}{x}=\frac{15}{100}[/tex] ; cross multiply.
15x = 500
x = 33.33 kilometers
therefore, the race is 33.33 kilometers.
Answer:
33.33
Step-by-step explanation:
15%/100 and 15%=5KM 5=15% so make it 1% 5÷15=0.3333..... = 1% therefore time it to 100×0.3333 (1%) = 33.33KM is the total race KM

Answer:
2/7
Step-by-step explanation:
This is easy! No need to over think it btw!
1) whenever you divide by a whole number such as in this case;4. You need to put a 1 under 4... like this: 4/1 (so it can become a fraction!)
2) Use KEEP, CHANGE, FLIP when you are dividing fractions!
8/7 --> you keep that number
÷ ---> × = you change the division sign into multplication sign
4 ---> 1/4 = you put 1 over 4 and flip it which you get from 4/1 --> 1/4
3) Your would look like this....
8/7 * 1/4 = ?
4) Muliply horizontally; 8 * 1 = 8 , 7 * 4 = 28
5) You get 8/28 Don't forget to simplify!!!
6) 8/4 / 32/4 = 2/7
ALSO, here's an example of KEEP, CHANGE, FLIP:

On what intervals are the function's values positive?
10.
What are the zeros of the function?
Answer:
See step by step
Step-by-step explanation:
To find if a function intervals are possible, make sure the points are above the x axis.
The graph is getting positve around x=-3 but it isn't positive yet.
The graph is positve until x=-1
The graph becomes positive again again at x=2 and is positive infinitely forever.
So let set up our interval
We are going to start at -3 since that where it start getting positive, we then going to use the greater than sign since it get positve as we go to the right as of right now. We use the greater than becuase we are not going to include -3 as our solutions.
We then use a less than sign since the answer must be less than -1 becuase around-1 it start getting negative.
It becomes positive again at x=2 so since we going to left to right use the greater than sign becuase we are not including 2.
It infinitely becomes positive so our interval is x must be cause greater than w becuase it can be any interval greater than two.
[tex] - 4 > x < - 1[/tex]
and
[tex] 2 < x[/tex]
The roots or zeroes are the x intercept of the graph,(when y=0, what is the x value.)
The x intercepts are -3 and 2.
