Answer:

$\huge \boxed{20}$

Step-by-step explanation:

The angles add up to 90 degrees.

x + 2x + x + 10 = 90

Combine like terms.

4x + 10 = 90

Subtract 10 from both sides.

4x = 80

Divide both sides by 4.

x = 20

Answer:

x = 20

Step-by-step explanation:

Since we are solving for x let's create an equation

The whole thing is equal to 90 degrees, so we can keep that on one part of the equation

x + 2x + (x + 10) = 90

First let's add all of the x's together making it 4x + 10 = 90

Now subtract 10 from each side 4x = 80

Lastly, divide 4 on each side

x = 20

The concession stand sells hot dogs and soda during Beck high school football games John bought six hotdogs and four Sotos and p

siniylev [52]

Question is not proper, Proper Question is given below;

The concession stand sells hot dogs and drinks during their high school foot ball game. John bought 6 hot dogs and 4 soda and paid $6.70. Jessica bought 4 hot dogs and 3 Soda and paid $4.65. What is the price of a hot dog and a Soda?

Answer:

Hot dog cost for $0.75 and Soda cost for $0.55.

Step-by-step explanation:

Let the Price of each Hot dog be x.

Also Let the price of each Soda be y.

Now Given:

John bought 6 hot dogs and 4 Soda and paid $6.70.

Now Total Money paid by John is equal to Sum of Number of hot dogs he bought multiplied by Cost of each hot dogs and Number of Soda he bought multiplied by cost of each soda.

Framing in equation form we get;

$6x+4y=6.70$

Dividing by 2 on both sides we get;

$\frac{6x}{2}+\frac{4y}{2}=\frac{6.70}{2}\\\\3x+2y=3.35 \ \ \ \ equation\ 1$

Also Given:

Jessica bought 4 hot dogs and 3 Soda and paid $4.65.

Now Total Money paid by John is equal to Sum of Number of hot dogs he bought multiplied by Cost of each hot dogs and Number of Soda he bought multiplied by cost of each soda.

Framing in equation form we get;

$4x+3y=4.65 \ \ \ \ equation \ 2$

Multiplying equation 1 by 3 we get;

$3(3x+2y)=3.35\times3\\9x+6y=10.05 \ \ \ \ equation \ 3$

Also Multiplying equation 2 by 3 we get;

$2(4x+3y)=4.65\times 2\\8x+6y = 9.3 \ \ \ \ equation\ 4$

Now Subtracting equation 4 from equation 3 we get;

$(9x+6y)-(8x+6y)=10.05-9.3\\9x+6y-8x-6y= 0.75\\x=\$0.75$

Now Substituting the value of x in equation 1 we get;

$3x+2y=3.35\\\\3\times 0.75+2y = 3.35\\\\2.25+2y=3.35\\\\2y = 3.35-2.25\\\\2y = 1.1\\\\y=\frac{1.1}{2}= \$0.55$

Hence Hot dog cost for $0.75 and Soda cost for $0.55.

A florist had six hundred eight flowers. She wanted to put them into forty-two bouquets with the same number of flowers in each.

Ymorist [56]

If you meant 680 it would be 16 if you meant 608 it’s would be 14 bouquets.

Hope this helps

Please help... How many odd perfect squares are between 5 and 211?

frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

3² = 9

5² = 25

7² = 49

9² = 81

11² = 121

13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Answer: 11x-3y = 32

---------------------------------------------------------------

Explanation:

The given points are
A = (-4,-2)
B = (4,4)
C = (18,-8)

First we'll use points A and C to find the slope of line AC
m = (y2-y1)/(x2-x1)
m = (-8-(-2))/(18-(-4))
m = (-8+2)/(18+4)
m = -6/22
m = -3/11
The slope of AC is -3/11

Take the negative reciprocal of this slope
Flip the fraction: -3/11 -----> -11/3
Flip the sign: -11/3 ----> +11/3 = 11/3

The slope of AC is -3/11 while the slope of any line perpendicular to AC is 11/3
Let m = 11/3 and (x,y) = (4,4) which are the coordinates of point B
Plug these values into slope intercept form and then solve for b
y = mx+b
4 = (11/3)*4+b
4 = 44/3+b
4 - 44/3 = 44/3+b-44/3
b = 4 - 44/3
b = 12/3 - 44/3
b = (12 - 44)/3
b = -32/3

Since m = 11/3 and b = -32/3, we go from this
y = mx+b
to this
y = (11/3)x-32/3

Now clear out the fractions and get the x and y variables to one side
y = (11/3)x-32/3
3y = 3*[ (11/3)x-32/3 ]
3y = 11x - 32
3y-11x = 11x-32-11x
-11x+3y = -32
-1*(-11x+3y) = -1*(-32)
11x-3y = 32

The equation of the through B that is perpendicular to AC is 11x-3y = 32 (this equation is in Ax+By = C form which is called standard form)
This is better known as the altitude through B
