Solve the following problem. Round to one decimal place if necessary.

Answer:

45degree

Step-by-step explanation:

hopes it help you

Let us consider x be one of the two equal complementary angles.

x + x = 90o

2x = 90o

2x = 45o

∴ 45o is equal to its complement.

Answer:

D. quadratic; y = 2.5x2

Step-by-step explanation:

Answer:

A. quadratic; y = 2.5x2

Step-by-step explanation:

Answer:

Option (1)

Step-by-step explanation:

x               -2              -1                 0                    1                   2

y               10            2.5                0                  2.5                3.0

Ist difference,

   = -2.5

  = 2.5

  = 7.5

2nd difference,

   = 5

  = 5

  = 5

Since 2nd difference is common, given table represents a quadratic equation.

Let the equation is,

y = ax²+ bx + c

For a point (0, 0) passing through the quadratic equation,

0 = c

Therefore, quadratic equation is y = ax² + bx

Since ordered pair (-1, 2.5) passes through the graph of the function,

2.5 = a(-1)² + b(-1)

a - b = 2.5 ------(1)

For another point (1, 2.5)

2.5 = a(1)² + b(1)

a + b = 2.5 ------(2)

By adding equations (1) and (2),

2a = 5

a = 2.5

and from equation (2)→ y = 0

Therefore, equation of the quadratic function given in the table is y = 2.5x²

Option (1) is the answer.

Answer:

Step-by-step explanation:

24 eggs = 10 dollars

3 loafs of bread for 5 dollars each x 3 = amount together so 15

5x8=40 dollars for all drinks, so

10+15+40

Hey there! I'm happy to help!

First, we have our eggs, which cost $10

10

Then, we have our 3 loaves of bread. Each one costs $5. 5×3 is 15, so we will add this to our total.

10+15

And then we have our 5 drinks, each costing $8. 8×5 is 40, so we will add 40 to our total.

10+15+40=65

So, we need $65 dollars to go out shopping.

6 and 9 together equal 15

Answer:

It is 171

Step-by-step explanation:

[tex] {x}^{2} - 3y + x[/tex]

substitute for x and y:

Answer:

The measure of angle C is 92°

Step-by-step explanation:

In a quadrilateral opposite angles are supplementary (Angles add up to 180°)

So since we have two opposite angles already set up the equation:

(x+24)+(x+10) = 180

Combine like terms - x+x+24+10 = 180 → 2x+34 = 180

Cancel out the constant to solve for x: 2x+34-34 = 180-34

Divide both sides by 2 so x is isolated: 2x/2=146/2

Solve: x=73

Now that we know x = 73 we can find angle C by setting up the equation:

Let C represent the unknown angle of ∠C

73+15+C=180

Combine like terms: 88+C=180

Isolate C: 88-88+y=180-88

Solve for C: C=92

don't u just add the side lengths and then get the answer?

Answer:

y = -32

Step-by-step explanation:

I'm not completely sure of what you're asking but less than means you subtract the number from 50.

So...

50 - y = 82

Subtract 50 from both sides

-y = 32

Divide both sides by -1

y = -32

Answer:

I think that it might be (−∞,1/2)

-Chetan K

Step-by-step explanation:

Ok they need to make $1,260.

Each t-shirt sells for $12 but they only make half that amount $6

So far 85 t-shirts have been sold

85 * 12 = 1,020

Ok but remember its half that amount-

1,020 / 2 = 510

So far they have $510 raised.

1260 - 510 = 750

They still need to raise $750.

If we divide $750 / 6 = 125

So that's our answer, now if we wanna verify-

125 * 12 = 1500

1500 / 2 = 750

So after revising, we are left with the answer 125, Mathewson middle school must sell 125 more t-shirts to make the desired amount.

Hope this helps! :)

Answer:

x = 10

Step-by-step explanation:

Assuming that the triangles are similar we can use ratios to solve for x.

x / 6 = 35 / 21

Using cross products we acquire,

35 * 6 = 210

21 * x = 21x

21x = 210

Divide both sides by 21

21x/21=x

210/21=10

x = 10

Answer:

if the probability is 7:2, then there are 9 possible outcomes

so do 7 divided by 9 and Jim has a 77% chance of winning

Probability helps us to know the chances of an event occurring. The probability that Jim will win is 22.22%.

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that the odds against Jim beating a friend at golf are 7:2. Therefore, the ratio of the number of games that Jim's friend wins to the number of games that Jim wins is,

Number of games Jim's friend wins/ Number of games Jim wins = 7/2

Now, the total of games they both play will be 9, which is the sum of 7 and 2. Therefore, the probability that Jim will win is,

Probability (Jim wins) = Number of games Jim wins / Total number of games

= 2 / 9

= 22.22%

Hence, the probability that Jim will win is 22.22%.

Answer:

7 - (5- 3) + 4 = 9

Step-by-step explanation:

we use a scientific calculator and add the brackets and if it gives the answer 9 than its correct.

[tex] \huge \boxed{\mathfrak{Answer} \downarrow}[/tex]

[tex] \large \bf\frac { 5 - 3 i } { - 2 - 9 } \\ [/tex]

Subtract 9 from -2 to get -11.

Given the function w:

[tex] \displaystyle \large{w(x) = {x}^{2} + 1 }[/tex]

Since we want to find w(x+3), the input would be x+3.

Substitute x = x+3 in.

[tex] \displaystyle \large{w(x + 3) = {(x + 3)}^{2} + 1 }[/tex]

Alternate Solution

The answer above works if you want it in vertex form. For this alternate solution, I will convert the function in standard form.

As we know:

[tex] \displaystyle \large{ {(x + y)}^{2} = {x}^{2} + 2xy + {y}^{2} }[/tex]

Therefore:

[tex] \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 2(x)(3) + {3}^{2} } \\ \displaystyle \large{ {(x + 3)}^{2} = {x}^{2} + 6x+ 9}[/tex]

Now for function w:

[tex] \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 9+ 1 } \\ \displaystyle \large{w(x + 3) = {x}^{2} + 6x + 10}[/tex]

Hence:

The median of that data set is 9.

Sort the numbers from least to greatest and find the middle number (that should be your median)

If there are 2 numbers in the middle of the set, then you take the average and that would be your median.
