1 When y= 35, x = 22. If the value of y
varies directly with x, what is the value of y
when the value of x is 3 ?
A 113 C 227
B 26 13 D 45 1

Answer:

262440

Step-by-step explanation:

Answer:

There were 90 questions in the test.

Step-by-step explanation:

He missed 88 questions on the test and scored a 2%. This means that the 88 questions missed correspond to 100% - 2% = 98% of the total number of questions, which is x. So

[tex]0.98x = 88[/tex]

[tex]x = \frac{88}{0.98}[/tex]

[tex]x = 89.8[/tex]

Rounding up

There were 90 questions in the test.

Answer:

at least $450

Step-by-step explanation:

Let the amount she has in bank before depositing be x

If she had at least $550 in the bank after depositing, then;

x + 100 ≥ 550

Get the initial amount in bank

x ≥ 550 - 100

x ≥ 450

Hence the amount she has in the bank originally was at least $450

Step-by-step explanation:

The equation as a function of x is f(x)=9280-20x. Therefore, option B is the correct answer.

The given function is x/16 + y/320 - 29 = 0.

Functions are the fundamental part of calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x. Mapping or transformation is used to denote a function in math. These functions are usually denoted by letters such as f, g, and h. The domain is defined as the set of all the values that the function can input while it can be defined. The range is all the values that come out as the output of the function involved. Co-domain is the set of values that have the potential of coming out as outputs of a function.

Now, the LCM of denominators 16 and 320 is 320.

So, 20x/320 + y/320 - 9,280/320 = 0

⇒20x+y-9280=0

⇒y=9280-20x

The equation as a function of x is f(x)=9280-20x. Therefore, option B is the correct answer.

Answer:

if ur trying to solve it x = -18

Step-by-step explanation:

Answer:

x=4, y=16

Step-by-step explanation:

Since y is alone on one side of both equations, that means that the equations are equal.

[tex]2x+8=3x+4\\[/tex]

Put like terms on the same side of the equations. I put the numbers on the left and the Xs on the right. To do this subtract 4 from both sides. You will get:

[tex]2x+4=3x[/tex]

Next, I subtracted the 2x from both sides;

[tex]4=x[/tex]

For y, just substitute the x in the equation with 4. Will work for either equation.

[tex]y= 3(4)+4\\y= 12+4\\y=16[/tex]

Or

[tex]y=2x+8\\y=2(4)+8\\y=8+8\\y=16[/tex]

Therefore, y=16

Answer:

Part A)  

Part B)  

Part C)  

Part D)  

Step-by-step explanation:

we know that

The probability of an event is the ratio of the size of the event space to the size of the sample space.

The size of the sample space is the total number of possible outcomes

The event space is the number of outcomes in the event you are interested in.

so

Let

x------> size of the event space

y------> size of the sample space

P=x/y

Part A) What percent of all children are girls?

we have that

y= 360 children

x=198 girls

substitute

p = 198/360 0.55

Find the percentage

0.55*100=55%

Part B) What percent of all children are boys?

we have that

y=360

x=360-198

substitute

p= 162/360=0.45

Find the percentage

0.45*100=45%

Part C) The number of girls is what percent of the number of boys?

we have that

y=162

x=198

substitute

p=198/162=1.22

Find the percentage

1.22*100= 122%

Part D) The number of boys is what percent of the number of girls?

we have that

y=198 girls

x=162 boys

substitute

p=162/198=0.8182

Find the percentage

0.8182*100=81.82%

The percentage of the school are girls is 55%.

The percentage of the school are boys is 45%.

The number of boys in the school is 162.

The number of girls in the school is 198.

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, In a school containing 360 children, 198 are girls.

Therefore, The percentage of the school are girls is,

(198/360)×100%.

= 55%.

The percentage of the school are boys is,

= [(360 - 198)/360]×100%.

= 45%.

Or The percentage of the school are boys is, (100 - 55)% = 45%.

The number of boys in the school is,

(360 - 198).

= 162 boys.

The number of girls in the school is 198.
