hi uhm what am i supposed to figure out?

Step-by-step explanation:

Gina did not use the same ratio as her teacher. I know this because 4:3 is not a simplified version of 9:6. If her teacher were to use a 8:6 ratio then it would’ve been the same.

Answer:

30%

This is the only way I know this would make sense

Step-by-step explanation:

40+20+10=70

100-70=30

Answer:

17 nickels

5 quarters

Step-by-step explanation:

Let n = no. of nickels

22 - n = no. of quarters

Each quarter is 25 cents and each nickel is 5 cents

5n = total amount of money in cents for the nickels

25(22 - n) = total amount of money in cents for the quarters

Since the total amount of money is $2.10 or 210 cents we have the equation

5n + 25(22 - n) = 210

5n + 550 - 25n = 210

-20n + 550 = 210

-20n = -340

n = 17 nickels

22 - n = 22 - 17 = 5 quarters

Now, you don't need to do all that I did.  I explained in detail what is going on in this problem.  All that you would need to do is write this:

let n = no. of nickels

22 - n = no. of quarters      and then write the equation and solve

5n + 25(22 - n) = 210

??                                          OK?

Answer:

Step-by-step explanation:

I believe this question is coming from a statistical data, which for whatever reasons is not present here. If Julie says the most amount of time spent, it meant that the time most time people spent on the homework. And if she says the least amount of time. This means that the least number of time people spent on the homework.

Then again, she says it is half times, this means that if 5 people spent the most amount of time in doing something, then 10 people must have spent the least amount of time doing the same exact thing.

I hope you understand

Answer:

Hi how are you doing today Jasmine

Answer:

12.5 Sq inches

Step-by-step explanation: 225 is the area and the formula for area is b*h (base times height) and from the problem, you can see that 18 inches is the height. In this case you would do 225/18 which gives you 12.5 sq inches.

Answer:

(69,979)

Step-by-step explanation:

In the coordinates, x is represented as 69. We can now insert this into the equation.

y = 13x + 82

Now to insert x.

y = 13(69) + 82

Now we can multiply 13 by 69.

13*69 = 897

Now fix the equation.

y = 897 + 82

Now add to get our y.

897 + 82 = 979

Substitute into the equation.

y = 979

And there is our answer. We now need to put this into the coordinates.

And we get our final answer of (69,979).

Hope this helps. Have a nice day.

Answer:

Answer is A

Step-by-step explanation:

you first take the same like terms

8c+6-3c-2

8c and -3c are like terms 8c-3c=5c

+6 and -2 are like terms 6-2=4

5c+4

Given:

The function is:

[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]

To find:

All the possible rational zeros for the given function by using the Rational Zero Theorem.

Solution:

According to the rational root theorem, all the rational roots are of the form [tex]\dfrac{p}{q},q\neq 0[/tex], where p is a factor of constant term and q is a factor of leading coefficient.

We have,

[tex]f(x)=10x^5+8x^4-15x^3+2x^2-2[/tex]

Here,

Constant term = -2

Leading coefficient = 10

Factors of -2 are ±1, ±2.

Factors of 10 are ±1, ±2, ±5, ±10.

Using the rational root theorem, all the possible rational roots are:

[tex]x=\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].

Therefore, all the possible rational roots of the given function are [tex]\pm 1,\pm 2,\pm \dfrac{1}{2}, \pm \dfrac{1}{5},\pm \dfrac{2}{5},\pm \dfrac{1}{10}[/tex].

Answer:

43 = x

Step-by-step explanation:

well so you have 127 degrees = (2x + 41)

so get the x by itself

127 - 41 = 86

2x + 41 - 41 = 2x

86 = 2x

86 / 2 = 43

2x / 2 = x

43 = x  

The value of x is 43°.

Here,

The iron cross is a skiing trick in which the tips of the skis are crossed while the skier is airborne.

A photo shows the tips of the skis crossed each other while performing iron cross in skiing.

Two pairs of opposite angles are formed during crossing.

One pair of the opposite angle is 127° and (2x + 41)°.

We have to find the value of x.

What is Vertically opposite angles?

The angles opposite each other when two lines cross called Vertically opposite angles.

Now,

Two pairs of opposite angles are formed during crossing.

One pair of the opposite angle is 127° and (2x + 41)°.

Clearly, Both angle are equal;

2x + 41 = 127

2x = 127 - 41

2x = 86

x = 43

Therefore, Value of x is 43°.

Answer:

y = 2x - 5

Step-by-step explanation:

Put it in point-slope form:

y + 7 = 2(x + 1)

y + 7 = 2x + 2

y = 2x - 5

Answer:

a = 7

Step-by-step explanation:

Let's solve your equation step-by-step.

3/5(a+5.25)=7.35

Step 1: Simplify both sides of the equation.

3/5(a+5.25)=7.35

(3/5)(a)+(35)(5.25)=7.35 (Distribute)

3/5a+3.15=7.35

Step 2: Subtract 3.15 from both sides.

3/5a+3.15−3.15=7.35−3.15

3/5a=21/5

Step 3: Multiply both sides by 5/3.

(5/3)*(3/5a)=(5/3)*(21/5)

a=7

Answer:

0.2187

Step-by-step explanation:

Americans consume on average 92 pounds of chicken per year, with a standard deviation of 10.3 pounds. What is the probability that a sample of 50 people will have consumed an average of 100 pounds or more?

We to find

x ≥ 100 pounds

To solve for the above question, we use the z-score formula

z = (x-μ)/σ, where

x is the raw score = 100 pounds

μ is the population mean = 92 pounds

σ is the population standard deviation = 10.3

Hence:

z = (100 - 92)/ 10.3

z = 8/1.46

z = 0.7767

Probability value from Z-Table:

P(x<100) = 0.78133

P(x>100) = 1 - P(x<100) = 0.21867

Approximately = 0.2187

Therefore, the probability that a sample of 50 people will have consumed an average of 100 pounds or more is 0.2187

Oh they are " similar "  triangles, so they are scale copies of each other

for 13)   they are saying those same marks on the sides means those segments are the same lengh.  so the bigger triangle takes 2 same lengths as does the smaller one.    Yes.. that does mean the bigger one is 2 times bigger than the smaller one.   sooo  just multiply that known side by 2 to find BD

so BD = 2 *8

BD = 16  :)

for 14)    same exact thing but in reverse

XY = 1/2 *8

XY = 4  :)

for 15)

I think that there is a line.... from U to V that isn't showing up in the photo,  using your camera for a photo of a screen seems .. hmm redundant.. just push "screen print" then paste what you copied into paint .  then show that pic... no phone cam required.  :? and the pic would be much much better quality.. no missing lines :/

anyway    so if there is in fact a line from U to V  then IK is that same 2 times bigger than UV

IK = 2*4

IK = 8

For 16)  this is getting to be the same thing over and over.. are you getting it? :)

DF = 2 *8
