Answer:

x = 8

y = radical 128

Step-by-step explanation:

Since this is a 45, 45, 90 triangle, the value of x is equal to the adjacent side -- 8.

To find y, use pythagorean theorem:

a² + b² = c²

8² + 8² = y²

128 = y²

y = radical 128

Answer:

angle N is 79, angle K is 22, angle P is 81, angle D is 76

Answer:

12 12 12 12 12 12 12 12 12 1 2 12 12

Answer:

Step-by-step explanation:

x + 90° + 73° = 180° ( being linear pair)

x = 180° - 163 °

x = 17°

Answer:

Measure of angle AD = 90 Degrees since its a right angle

Also

Measure of angle BC = 90 degrees as it is also a right angle.

Now,

From AD:

90 - 73 = 17 degrees

As  AD and BC are same concurrent angles. So,

x = 17 degrees

Answer:

4/11

Step-by-step explanation:

17 . Find the values of g(9) and h(-14) and add them together.

The function equations are given to find their values substitute 9 in g(x) and -14 in h(x)

20. They said f(x) = 2x + 9 and f(x) = 15 , which means they are equal to each other.

So write them as 2x + 9 = 15 , and solve the equation to find the value of x.

25. Here all you have to do is substitute 4 into the f(x) equation to find f(4)and you will have your answer.

Hope this helped!

Answer:

1/15

Step-by-step explanation:

Ms. Fox loves to eat cereal and she notices that she only has 1/3 of the box of cereal left. If she spread that amount across 5 days, how much cereal will she have for each day?

The amount of cereal she would have per day is calculated as:

5 days = 1/3 of the box

1 day = x

Cross Multiply

5 days × x = 1 day × 1/3 of the box

x = 1/3 ÷ 5

x = 1/3 × 1/5

x = 1/15 of the box

Answer:

  n = 8

Step-by-step explanation:

"By inspection" is an appropriate method.

We are asked to compare the expressions

  n·n

  8·n

and find the value(s) of n that makes them equal. By inspection, we see that n=8 will make these expressions equal. We also know that both expressions will be zero when n=0.

__

More formally, we could write ...

  n^2 = 8n . . . . the two formulas give the same value

  n^2 -8n = 0 . . . . rearrange to standard form

  n(n -8) = 0 . . . . . factor

Using the zero product rule, we know the solutions will be the values of n that make the factors zero. Those values are ...

  n = 0 . . . . . makes the factor n = 0

  n = 8 . . . . . makes the factor (n-8) = 0

Generally, we're not interested in "trivial" solutions (n=0), so the only value of n that is of interest is n = 8.

__

A lot of times, I find a graphing calculator to be a quick and easy way to find function argument values that make expressions equal.

Answer:

The actual distance is 56

Step-by-step explanation:

set up a proportion

1cm              14cm

          =

4km              x

cross multiply 56=x

so the actual distance is 56 km im pretty sure :)

Answer:

  $98.15

Step-by-step explanation:

2005 is 15 years after 1990. Using the formula we find ...

  c(15) = 63·1.03^15 ≈ 63·1.55797

  c(15) ≈ 98.152

An ounce of the chemical costs about $98.15 in 2005.

Answer:

The gradient AB is 3

Step-by-step explanation:

Here. we want to find the gradient AB

This is the same as finding the slope of the line that connects the two points

mathematically. we have this as;

m = (y2-y1)/(x2-x1)

(x1,y1) = (1,4)

(x2,y2) = (7,22)

m = (22-4)/(7-1) = 18/6 = 3

Answer:

3c - [tex]\frac{3}{2}[/tex] f - [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Given

[tex]\frac{1}{2}[/tex] (6c - 3f - [tex]\frac{3}{4}[/tex] ) ← multiply each term in the parenthesis by [tex]\frac{1}{2}[/tex]

= 3c - [tex]\frac{3}{2}[/tex] f - [tex]\frac{3}{8}[/tex]

Answer: x < -1.

Step-by-step explanation: That is the answer. Everything less than -1.

Answer:

x < -1

Step-by-step explanation:

Your answer is correct: it has an empty circle (which means it is either < or > not including). The arrow also points to the left, meaning less than or <

Answer:

28=x

Step-by-step explanation:

2/5=x/70

(70/1)(2/5)=x/70(70/1)

here you cancel 70 into 5 to get 14 and on the other side cancel both the 70s

14*2=x

28=x

Answer:

28

Step-by-step explanation:

multiply 2 * 70 then divide by 5

Answer:

10 kg water, 2 kg of sugar.....total of 12 kg of syrup

percentage of sugar is : 2/12 = 0.166 rounds to 0.17 = 17%

Step-by-step explanation:

Answer:

392.35

Step-by-step explanation:

35% + 35% is 70 % so 133 +133 is 70 % witch is 269.

next we need to figure out 30 percent and they give us 35 % so. you add to zeros to 30 because percentage is out of 100 and there are 2 zeros in 100. so it look like this

3000 ÷ 133 = 22.56 is 30% of 133

70% + 30% = 100%

269 + 22.56= 291.56 is your answer

Answer:

Explanation:

3x · 4 = 7x - (x + 17)

Simplify both sides of the equation

3x (4) = 7x − (x + 17)

3x (4) = 7x + −1 (x + 17) (Distribute the Negative Sign)

3x (4) = 7x + −1x + (−1) (17)

3x (4) = 7x + −x + −17

12x = 7x + −x + −17

12x = (7x + −x) + (−17) (Combine Like Terms)

12x = 6x + −17

12x = 6x − 17

Subtract 6x from both sides

12x − 6x = 6x − 17 − 6x

6x = −17

Divide both sides by 6

6x / 6 = −17 / 6

Simplify

x = ⁻¹⁷⁄₆

Turn the fraction into a decimal

-17 ÷ 6 = -2.83333333333
