-.At a fair hamburgers sell for $3.00 each and hot dogs sell for $1.50 each. The equation 3x + 1.5y = 30 describes the number of

NikAS [45]

Answer:

Part a) The y-intercept is the point (0,20) and the x-intercept is the point (10,0)

The graph in the attached figure

Part b) See the procedure

Step-by-step explanation:

The questions are

Part a) Find the intercepts and graph the function

Part b) What does each intercept represent?

Part a) Find the intercepts and graph the function

Let

x-----> the number of hamburgers

y ----> the number of hot dogs

we have

$3x+1.5y=30$

Remember that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$3(0)+1.5y=30$

$1.5y=30$

$y=20\ hot\ dogs$

The y-intercept is the point (0,20)

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$3x+1.5(0)=30$

$3x=30$

$x=10\ hamburgers$

The x-intercept is the point (10,0)

Plot the intercepts and graph the line

see the attached figure

Part b) What does each intercept represent?

The x-intercept is the number of hamburgers they can buy if they buy no hot dogs

The y-intercept is the number of hot dogs they can buy if they buy no hamburgers

A chemist is using 336 milliliters of a solution of acid and water. If 16.4% of the solution is acid, how many milliliters of ac

RUDIKE [14]

Answer:

Amount of acid = 55.1 mm (Approx)

Step-by-step explanation:

Given:

Amount of solution = 336 mm

Percentage of acid = 16.4%

Find:

Amount of acid

Computation:

Amount of acid = Amount of solution x Percentage of acid

Amount of acid = 336 x 16.4%

Amount of acid = 55.1 mm (Approx)

A boy had 11 coins in dimes their value is $1.70 how many of each does he have

REY [17]

He would have 4 quarters and 7 dimes. The reason is because 1 quarter is 25 cents. And a dime is 10 cents. Add it together and you would get $1.70. Hope this helps! Have a great day :)

What is the scale factor of this dilation?

Slav-nsk [51]

Answer: C) Three-fourths

I.e., the fraction 3/4

======================================================

Explanation:

Let's pick on the horizontal sides. Divide the image length Y'Z' = 9 over the corresponding preimage length YZ = 12 to get

(Y'Z')/(YZ) = 9/12 = 3/4 which is the scale factor

The scale factor is less than 1, meaning the image's lengths are shorter compared to the preimage's corresponding lengths.

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

Alternative Paths:

You can pick any other pair of corresponding sides to get the same result:

(X'Y')/(XY) = (7.5)/(10) = 75/100 = 3/4
(Z'X')/(ZX) = 6/8 = 3/4
