ASAP ANSWER THIS 2ST ANSWER I'LL MARK BRAINLIEST

Answer:

a unit means that we have one of something the unit rate means we have a rate for one or something we write the rate as a ratio with a denominator of 1

so false

Answer:A rate is a comparison of two different quantities with different units, one is generally time. Rates are always ratios, since they are comparing two different numbers as they compare two different quantities. Ratios are sometimes rates, but not always; we can compare different numbers without comparing measurements.

Answer:

50/100 or 1/2

Explanation:

A 50-50 chance that a randomly selected adult has pierced ears means there's is a 50 percent probability of randomly selecting an adult that has pierced ears. In other words, there is half chance of selecting such an adult. A zero or one probability means there is either no possibility of selecting an adult with pierced ears or it is sure that a random adult would have pierced ears

Answer:

Step-by-step explanation:

a) set up the variables

Let x represent the first number Then  y will represent the second number.

b) What is the equation that represents the above situation?

c) Solve the equation.

Substitute x in the second equation and solve for y:

Then find x

Answer:

[tex]\tt{34~and ~17 }[/tex]

Step-by-step explanation:

let the first number is =x

second number is =y

The sum of two numbers is 51 =x+y=51•••{1}

the greater number is twice the smaller number= x=2y••••••••{2}

According to the question,

[tex]\bold{ x+y=51 }[/tex]

[tex]\bold{2y+y=51 }[/tex] [tex]\because{ (x=2y ) }[/tex]

[tex]\bold{ 3y=51 }[/tex]

[tex]\bold{ y=\dfrac{51}{3} }[/tex]

[tex]\boxed{\blue{y=17 } }[/tex]

NOW put the value y in equation {2}

we get that,

[tex]\bold{ x=2×17 }[/tex]

[tex]\bold{ x=34 }[/tex]

Answer:

Step-by-step explanation:

The factors of 50 are 1,2,5,10,25,50;

The factors of 90 are 1,2,3,5,6,9,10,15,18,30,45,90.

So, as we can see, the Greatest Common Factor or Divisor is 10, because it is the greatest number that divides evenly into all of them.

Answer:

54

Step-by-step explanation:

The Median of the data 78,56,22,34,45,54,39,68,54,84

Median of a data is the value at the middle after rearrangement

Rearrange in ascending 0rder

22, 34, 39, 45), 54, 54, (56, 68, 78, 84

The two numbers at the middle are 54 and 54

Median = 54 + 54/2

Median = 108/2

Median = 54

Hence the median of the data is 54

Answer:

675

Step-by-step explanation:

675x0.04=27

Answer:  y = 1/4 x – 4

OR y = x/4 –4

m is the slope. b is the y-intercept.

Without numbers on the x and y axis, it may not be correct. But assuming a normal scale, the slope is positive 1/4 and the y-intercept is -4

Step-by-step explanation: To find the slope, m, determine  "rise over run"

Look for places where the graphed line crosses the grid at intersections. There seems to be such places at (–4,–5), (0,–4) and (4,–3)

The "rise" is the difference in y-values. Here, they increase by 1.

The "run" is the difference in x-values. Here they increase by 4.

So the slope is 1/4. Put that in place of m.

The graphed line crosses the y-axis at –4

That is the y-intercept.  Use -4 in the place of  b

Keep the y and x; substitute the values for m and b we found.

y = 1/4 x – 4

OR

y = x/4 – 4  This makes it clear that x is not in the denominator of the fraction, 1/4, and in calculations with given coordinates, the value of x will be divided by 4.

Answer:

7 and 1 are coefficients

Step-by-step explanation:

7 is next to m so it is a coefficient and 1 is a coefficient of b although you can not see it we already know it has a coefficient. 6 is a constant

Answer:

2 x 2 = 5 + y

4-5 =y

y= -1

4(-1)=-20 + 8 x 2

-4= 20+ 16

-4= 36

36+4=0

Ans) 40

Hey there!

The answer is 3

Parentheses

Exponents

Multiplication

Division

Addition

Subtraction

First we do 1 ÷ 1, which is 1. Now we are left with 3 + 1 - 1. Now, we do addition. 3 + 1 = 4. Then, subtraction. 4 - 1 = 3.

Hope it helps and have a great day!

Answer:

y = 127 + 5x

Step-by-step explanation:

Today Olivia has $127 in her savings account. She will deposit $5 into the account each week given x < 0

Let x = number of weeks Olivia deposits money.

y = Total pint of money that Olivia has in her account after x weeks

Hence, the function represents the amount in Olivias savings account after x weeks is ;

y = $127 + $5 × x

x < 0

y = 127 + 5x

Answer:

B 40

Step-by-step explanation:

y=5(8)=40

Probabilities are used to determine the chances of an event. Here, we want to calculate the chances of selecting a junior student. The probability of selecting a junior is 0.44.

From the table, we have:

[tex]Junior = 60[/tex]

[tex]Total = 137[/tex]

So, the probability of Junior is

[tex]P(Junior) = \frac{Junior}{Total}[/tex]

This gives:

[tex]P(Junior) = \frac{60}{137}[/tex]

[tex]P(Junior) = 0.437[/tex]

Approximate

[tex]P(Junior) = 0.44[/tex]

Hence, the probability of selecting a junior is 0.44

Answer: let's try C ( sorry if i'm wrong)

Step-by-step explanation:

Answer:

400 people english, 240 spanish, 120 vietnamese and 40 other

Step-by-step explanation:

50% is half of 800.

half of 800 is 400. 400 use english

to find 10 percent, you divide by 10. to find 30, you multiply that by 3.

80 times 3 is 240. 240 use spanish.

15 percent is 10 percent, which is 80, +40 because of the 5 percent

80+40 is 120. 120 use vietnamese.

5 percent is half of ten percent.

half of 80 is 40.

and it all adds up to 800

your welcome!:)

Answer:

English of the bat is just 400, because that is the half of 800

spanish - 240

vianameese - 120

other - 40

Step-by-step explanation:

to get the answered you just turn the percent into a decimal like 50%-0.5, 30%-0.3, 15%-0.15, and 5%- 0.05. Then you just multiply the decimal by 800. And the number you get is the amount of people!
