At a middle school, 46 students have blonde hair. There are 230 students in the school. What percent of the students have blonde hair?

Answer:

7.D) 107°

8. A) 123°

Step-by-step explanation:

To find the correct measurement of the angel the sum of the interior angels needs to equal 360°. Angels where the lines intersect with the circle would be both 90°. ( If that makes sense.)

90°+90°=180

180°+73°= 253°

360°-253°= 107°

The same for the second one. (those two angles would also be 90° each.)

90°+90°=180°

180°+57°=237°

360°-237°=123°

Answer:

x=4

y= 1/2

Step-by-step explanation:

The easiest way to solve this is to subtract the two equation from each other

wee have

  4x+2y=17

-  3x+2y=13

___________

x=4

Now that we know what x is we can solve for y

4(4)+2y=17

16+2y=17

2y=1

y= .5

Answer:

C.) Justin should have multiplie 3.8 and 7.9 first.

Step-by-step explanation:

To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Answer:

2

Step-by-step explanation:

sum of angles in a triangle is 180

(26x - 2) + 70 + 60 = 180

26x -2 = 180 - 70 - 60

26x - 2 = 50

26x = 52

x = 2

hope this helped

Answer:

D) 2

Step-by-step explanation: The interior angles of triangles will ALWAYS add up to 180 degrees. In this case 2 angles are already provided, 70 and 60, so adding those together (130) the remaining angle must be 50 (180-130=50). In 26x-2=50, x=2 is the only possible answer. (Feel free to ask any questions if you don't understand anything I said!)  

Answer:

6.73

Step-by-step explanation:

Remark

There might be an easier way to do this problem. I'm certain I don't know what it is. Begin by called WY = y

Givens

WY = y

WZ = x

XW = 25 - y

XZ = 24

YZ = 7

Equations

x^2 + y^2 = 7^2

(25 - y)^2 + x^2 = 24^2

Solution

x^2 = 7^2 - y^2

x^2 = 24^2 - (25 - y)^2

Since both xs are the same, you can equate the right side of the equations.

7^2 - y^2 = 24^2 - (25 - y)^2                 Expand the brackets

7^2 - y^2 = 24^2 - (625 - 50y + y^2)    Remove the brackets.

7^2 - y^2 = 576 - 625 + 50y - y^2        Cancel the y^2. Combine 576 and 625

49  = - 49 + 50y                                    Add 49 to both sides

98 = 50y                                               Divide by 50

y = 1.96

Now use y to find x

x^2 + y^2 = 7^2

x^2 = 7^2 - 1.96^2

x^2 = 45.1584

x = 6.72

9514 1404 393

Answer:

  x = 6.72

Step-by-step explanation:

The triangles are all similar, so the ratios of corresponding sides are the same.

  short leg/hypotenuse = 7/25 = x/24

  x = 24(7/25)

  x = 6.72

Answer:

59

Step-by-step explanation:

We know that all the angles must add up to 180

so we have

38+2b-20+b-15=180

solve for b

3b+3=180

3b=177

b=59

Answer:

b=59

Step-by-step explanation:

angles in the triangle add up to 180

this would mean that

38 +2b-20 + b-15 = 180

if we simplify this then it would be

3+3b= 180

rearrange

3b = 177

b = 59

Answer: 5

Step-by-step explanation:

Find the prime factorization of both these numbers:

95 = 5 * 19

145 = 5 * 29

The largest common factor is 5

The product (2y - 6)² of the  algebraic expression gives 4y² - 24y + 36

An algebraic expression is an expression that is made up of variables and constants, along with algebraic operations like addition, subtraction, square root, etc.

The product (2y - 6)² can be written as:

(2y - 6)² = (2y - 6)(2y - 6)        (clear the parenthesis)

             = 2y(2y - 6) -6(2y - 6)

            = 4y² - 12y - 12y + 36

            =  4y² - 24y + 36

Step-by-step explanation:

Answer:

-0.375%

Step-by-step explanation:

Here, we want to calculate the percentage error

Mathematically;

% error = error/true value * 100%

error= the difference between the true value and the calculated

That is;

79.8-80.1 = -0.3

% error = -0.3/80.1 * 100%

% error = -0.375%

Answer:Answer: 5.2-p

Step-by-step explanation:

Let p be the price, in dollars, per pound of cherries.

Given : .Jackson buys a watermelon for $7.65 and 5 pounds of cherries.

Cost of 5 pounds of cherries = 5p

Now,

Cost of fruits to Jackson = 7.65+5p   (in dollars)

Tim buys a pineapple for $2.45 and 4 pounds of cherries.

Cost of 4 pounds of cherries = 4p

Now,

Cost of fruits to Tim = 2.45+4p   (in dollars)

Amount spent by Jackson more than Tim = (Cost of fruits to Jackson)-(Cost of fruits to Tim)

=  7.65+5p -(2.45+4p)

=  7.65+5p -2.45 - 4p

= 5.2-p

Hence , the required expression in terms of p = "5.2-p"
