Answer:
A
Step-by-step explanation:
3 cups of flour produces 2 batches of dinner rolls. So, if one batch makes 15 rolls, then 2 batches makes 30 rolls. Therefore, 3 cups of flour produces 30 rolls.
Laura wants to find how much flour she needs to make 12 rolls.
Here's the setup:
Let x be the number of cups of flour needed. Then,
(3 cups of flour)/(30 rolls)=(x cups of flour)/(12 rolls)
This is the set up for all equations involving ratios. The units should be consistent. Notice how I have flour/rolls=flour/rolls.
It is not necessary to solve the equation, but you should to make sure your answer makes sense. By cross-multiplying, we get x=(3*12)/30 or 1.2 cups.
This solution makes sense. Because 3 cups of flour produces 30 rolls, one cup produces 10 rolls. We need slightly more than 1 cup to get 12 rolls.

w = 7d + 13, which statement is
true?
A. The independent variable is w.
B. The independent variable is d.
C. The dependent variable is 7.
D. The independent variable is 7.
Answer:
b
Step-by-step explanation:
this is me
The independent variable is found to be d.
What is an independent variable?An independent variable can be defined as a variable that can take any value which implies it is not dependent on any other variables.
The example can be given as y = x + 2, here x is an independent variable.
The given algebraic expression w = 7d + 13
There are two terms 7d and 13.
Here, the variable term is 7d.
And, the value of w depends on d which implies that d is the independent variable.
Hence, in the given expression the independent variable is d.

UGH! RSM!!!!!!!!!!!!!!!!!!!!! John's family visited his grandmother over the weekend. The drive to her house took 2 hours at their usual speed. the trip home took 15 minutes longer because traffic was bad and they had to drive 5 mph slower. How many miles away is john's grandmother's house? will give BRAINLIEST! +10pts!
Answer:
90 miles!
Step-by-step explanation:
there are two parts to the problem, meaning you'll need 2 equations.
let's call the distance TO the grandma's house d1, and BACK from the grandma's house d2.
KEY:
time TO g'ma house= t1
time FROM g'ma house=t2
(replace the t's with 's' for speed, with the '1' for to, and '2' for from)
(distance is a constant so d1 is always equal to d2).
-------------
d1=s1+t1, d2=s2+t2
we know what t1 is. 2 hours.
d1=s1•2
meaning that d2 is also equal to that.
s1•2=(s1-5)•2 1/4
2s1=2 1/4 s1-11 1/4
11 1/4= 2 1/4 s1-2s1
11 1/4 = 1/4 s1
s1 (to g'ma)=45 mph
distance is speed times time.
so 45•2 (hr) = 90.

Answer:
1152 ft^2
Step-by-step explanation:
There are 7 faces on this solid.
I will label the faces and will calculate each area with an explanation.
Faces 1 and 2:
The front face and the back face are congruent and have 5 sides each. Each face is a rectangle with a triangle above it. The lower rectangular part has dimensions 9 ft by 12 ft. The triangle above the rectangle has base 9 ft and height 16 ft - 12 ft = 4 ft.
Each face is a rectangle and a triangle.
area = area of rectangle + area of triangle
area = LW + bh/2
area = 9 ft * 12 ft + 9 ft * 4 ft/2 = 108 ft^2 + 18 ft^2 = 126 ft^2
This is area of of face 1, the front face. Face 2, the rear face has the same area.
A1 = 126 ft^2
A2 = 126 ft^2
Face 3: The bottom of the solid is a rectangle measuring 9 ft by 20 ft
area = LW
area = 9 ft * 20 ft = 180 ft^2
A3 = 180 ft^2
Faces 4 and 5:
The left vertical face and the right vertical face are congruent rectangles measuring 12 ft by 20 ft.
area = LW
area = 12 ft * 20 ft = 240 ft^2
A4 = 240 ft^2
A5 = 240 ft^2
Faces 6 and 7 are the top right and left inclined rectangles. They are congruent, and each one has dimensions 6 ft by 20 ft.
area = LW
area = 6 ft * 20 ft = 120 ft^2
We need 2 of these area.
A6 = 120 ft^2
A7 = 120 ft^2
total surface area = A1 + A2 + A3 + A4 + A5 + A6 + A7
total surface area = 126 ft^2 + 126 ft^2 + 180 ft^2 + 240 ft^2 + 240 ft^2 + 120 ft^2 + 120 ft^2
total surface area = 1152 ft^2
