Answer:

oojjojojojo

Step-by-step explanation:

gjj h 7/4 to the third power Chelsea is making a kite in the shape of a triangle. To determine if the triangle is a right triangle, Chelsea completed the following steps.

Step 1:

Find the side lengths of the triangle: 30 inches, 24 inches, 18 inches.

Step 2:

Substitute the values into the Pythagorean theorem: 18 squared + 24 squared = 30 squared.

Step 3:

Combine like terms: (18 + 24) squared = 30 squared.

Step 4:

Evaluate each side: 1764 not-equals 900.

Chelsea says the triangle is not a right triangle. Which best describes the accuracy of her explanation?

The triangle is actually a right triangle. In step 2, Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is not a right triangle, but in step 2 Chelsea incorrectly substituted the values into the Pythagorean theorem.

The triangle is actually a right triangle. In step 3, Chelsea incorrectly rewrote the expression on the left side of the equation.

Answer: 4

Step-by-step explanation:

Change the 2.5 to an improper fraction, then multiply by the reciprocal of 5/8.

[tex]2\frac{1}{2} /\frac{5}{8} =\frac{5}{2}*\frac{8}{5}=\frac{40}{10} =4[/tex]

Conversion a mixed number 2 1/

to a improper fraction: 2 1/2 = 2 1/

= 2 · 2 + 1/

= 4 + 1/

= 5/

To find new numerator:

a) Multiply the whole number 2 by the denominator 2. Whole number 2 equally 2 * 2/

2

= 4/

b) Add the answer from previous step 4 to the numerator 1. New numerator is 4 + 1 = 5

c) Write a previous answer (new numerator 5) over the denominator 2.

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 5/

Answer:

16.39

Step-by-step explanation:

Solution 1: You can turn the words into Algebra so What (x) is(=) 1.10 of (multiply)14.9, So x = 1.10 (14.9). x= 16.39

When you see the word what, place an 'x', is means '=', 110% = 1.10

Solution 2: Notice how 100 percent is already 14.9 so 110% should be greater than 14.9, so we're missing another 10%, and 10% of 14.9 is 1.49 just by moving the decimal over.  So you would need 14.9 + 1.49 more, so a total of 16.39.

Answer:

Adult ticket is $6

Student ticket is $4, as you said.

Step-by-step explanation:

We'll call adult tickets x and student tix y.

14x + 11y = 128

14x + y = 88

First, solve the second equation for y in terms of x:

y = 88- 14x

Then substitute that for y into the first equation:

14x + 11(88-14x) = 128

14x + 968 - 154x = 128

-140x = -840

x = 6  The adult ticket is $6, like you said.

Now take that and solve for y:

y = 88 - 14(6)

y = 88 - 84

y = 4 The student ticket is $4, as you said.

Hope this helps. Feel free to ask questions so you can understand.

Answer:

-25 and -4

Step-by-step explanation:

to solve this, you need to use the sum product pattern. this means you're going to take the x factor, 29x and separate it into it's squares.

(x^2+25x)+(4x+100)

then you take out the common factor in each separated equation

x(x+25)+4(x+25)

you see that the items in the parentheses are the same, this means that this is one of the equations you will use when factoring. the rest of the equation that is left out (the common factors) is the other equation

(x+25)(x+4)

to get the zeroes, you set each equation equal to zero and solve

x+25=0           x+4=0

x= -25             x= -4

profit %=?

Step-by-step explanation:

The profit percentage is 4% .

Profit percentage (%) is the amount of profit expressed in terms of percentage. This profit is based on the cost price .

Formula for profit percentage is:

(Profit/Cost Price) × 100

where,

Profit = Selling price - Cost price

According to the question

Let Cost price of the article = 100x

marked price is 30% above the cost price

i.e  marked price = [tex]\frac{130}{100} * 100x[/tex]

                            = 130 x

selling price of an article is 20% less than its marked price

i.e Selling price of the article = [tex]130x * \frac{100-20}{100}[/tex]

                                                = [tex]130x * \frac{80}{100}[/tex]

                                                = 104 x

Now ,

Profit = Selling price - Cost Price

Profit = 104x -100x

Profit = 4x        

Profit percentage =   [tex]\frac{Profit}{Cost PRice} *100[/tex]

substituting the values in formula

Profit percentage =  [tex]\frac{4x}{100x} *100[/tex]

Profit percentage =  4%

Hence, the profit percentage is 4% .

Answer:

y=7x-6

Step-by-step explanation:

You would first pick two coordinates in this case would be ( 0, -6), (1,1). You would find your slope by using the formula y2-y1/x2-x1. Which would give you a slope of 7/1 which is equal to 7. Then you would use point slope formula which is y-y1=m(x-x1). would would plug in the numbers and it would say

y-(-6)=7(x-0). Then you would simplify the y-(-6) which would be y+6 then you would distribute the 7. Your whole equation would look like y+6=7x+0. Then you would use inverse operations and subtract -6 from the left side of the equals and subtract it from 0 giving you -6. Therefore your whole equation would be y=7x-6. Hoped this helped.
