Answer:

7) 1.75c+7.50. If you knew the amount of cupcakes you would multiply that number by 1.75, but you don't know it, so we represent it with c. If you only pay the 7.50 one time, then there's nothing to multiply it to.

8) $929.84. Multiply 36 gallons × $3.19 per gallon, and you get $114.84. Then, add the $815 for the Airbnb and you get $929.84

divide 300 feet by 50 which is 6, divide 125 ft by 50 which is 2.5. Therefore your dimensions are 6 in by 2.5 in

if you're in putting in the computer it may want 2.5 in fraction form which is 2 1/2 in or in improper fraction form 5/2 in

find the coordinates of p so that p partitions segment ab in the part to whole ratio of 1 to 4 with a(-5,4) and b(7,-4)

scoray [572]

Answer:

$p(x,y) = (-2.6 ,2.4)$

Step-by-step explanation:

Given

a(-5,4) and b(7,-4)

Required

Partition P

Given that the segment ab is divided into ratio;

The coordinates of point p can be calculated using ratio formula given below

$p(x,y) = (\frac{mx_2 + nx_1}{m+n} ,\frac{my_2 + ny_1}{m+n})$

Where m and n are the ratio; m = 1 and n = 4

$(x_1, y_1) = (-5,4); \\(x_2, y_2) = (7,-4)$

So,

$p(x,y) = (\frac{mx_2 + nx_1}{m+n} ,\frac{my_2 + ny_1}{m+n})$ becomes

$p(x,y) = (\frac{1 *7 + 4 * -5}{1+4} ,\frac{1 * -4 + 4 * 4}{1+4})$

$p(x,y) = (\frac{7 + -20}{5} ,\frac{-4 + 16}{5})$

$p(x,y) = (\frac{-13}{5} ,\frac{12}{5})$

$p(x,y) = (-2.6 ,2.4)$

Hence, the coordinates of p are (-2.6,2.4)

During the summer, Heather has a two part-time jobs. She earns $7 an hour as a life guard and $10 an hour as a tutor. This week,

Kazeer [188]

Answer:

Step-by-step explanation:

Lifeguard=x

tutor=35-x

7x+10(35-x)=290

7x+350-10x=290

-3x=-60

x=20 hours as a lifeguard ($140)

35-x=15 hours as a tutor ($150)

adds to $290.

Hope that helps! :)
