At a baseball game, a vender sold a combined total of 170 sodas and hot dogs. the number of hot dogs sold was 50 less than the number of sodas sold. find the number of sodas sold and the number of hot dogs sold

Answers

Let the number of sodas sold be x and the number of hotdogs sold be y. We can assemble a system of equations from the information given and solve.

x+y=170 (We know that soda + dogs is 170)

x-50=y (We know that dogs is equal to 50 less than sodas)

We can use substitution to solve this system of equations.

x+y=170

Sub in the value of y from the second equation

x+(x-50)=170

2x-50=170

2x=220

x=110

We now know the number of sodas sold was 110. Lets now plug this value into the equation to solve for y.

x+y=170

110+y=170

y=60

So, there were 60 hotdogs sold and 110 sodas sold.

Write a real-world problem that could be represented by the following equation. 70 + 5x = 40 + 10x

Answers

Jack wants to paint his house. he collected quotations from two different painters. The first painter's total cost in terms of the number of hours, (x), worked was modelled as f(x) = 70 + 5x, while that of the second painter was g(x) = 40 + 10x. Jack knows that it will take about 6 hours to paint the house. He figured out that the cost quoted by the two painters is equal for 6 hour of work.

Triangle TUV is similar to triangle XYZ. Which of the following statements is true?

Answers

Answer:

Option B. The slope of VT is equal to the slope of ZX

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

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

step 1

Find the slope VT

we have

V(-7,-3),T(-4,0)

substitute in the formula

$m=(0+3)/(-4+7)$

$m=(3)/(3)$

$m_V_T=1$

step 2

Find the slope ZX

we have

Z(0,4),X(6,10)

substitute in the formula

$m=(10-4)/(6-0)$

$m=(6)/(6)$

$m_Z_X=1$

therefore

The slope of VT is equal to the slope of ZX

Answer:

The slope of VT is equal to the slope of ZX.

Step-by-step explanation:

Two triangles are similar if the slopes of corresponding sides are equal.

In triangle TUV, TU is vertical, so the slope is undefined. The side UV is horizontal, so the slope is zero.

Determine the slope of the VT using the slope formula. Point V is at (-7, -3), and point T is at (-4, 0).

slope=y^2-y1/x^2-x1

=0-(-3)/-4-(-7)

=3/3

In triangle XYZ, XY is vertical, so the slope is undefined. The side YZ is horizontal, so the slope is zero.

Determine the slope of the ZX using the slope formula. Point Z is at (0, 4), and point X is at (6, 10).

slope=y^2-y1/x^2-x1

=10-4/6-0

=6/6

Compare the slopes of corresponding sides of the two triangles.

Sides TU and XY have undefined slopes.

Sides UV and YZ have zero slopes.

Sides VT and ZX have slopes of 1.

Therefore, the following statement is true.

The slope of VT is equal to the slope of ZX.

A factory processes 1,560 ounces of olive oil per hour. The oil is packaged into 24-ounce bottles. How many bottles dose the factory fill in 1 hour?

Answers

Answer:

65 bottles in 1 hour.

Step-by-step explanation:

A factory processed 1,560 ounces of olive oil per hour.

The oil is packaged in to 24-ounce bottles.

We will divide total number of ounces processed by one packaged bottle.

The number of bottles filled in 1 hour = $(1560)/(24)$

= 65 bottles

The factory will filled 65 bottles in 1 hour.
