Linda's recipe makes 20 chocolate candies. She uses: 1 cup cream 3 cups dark chocolate Using Linda's recipe: 2. How much dark chocolate will you need to make 60 candies? Write proportion and solve.
Answer:
9 cups
If x represents the number of cups of dark chocolate needed for 60 candies, the proportion can be ...
cups/candies = 3/20 = x/60
Multiplying by 60 gives ...
x = 60(3/20) = 9
You need 9 cups of chocolate for 60 candies.

Answer:
a. 53.68
b. 53.53
Step-by-step explanation:
a. Step 1: Approximate the value for [tex]\sqrt{62}[/tex]:
Since [tex]\sqrt{62}[/tex] is close to [tex]\sqrt{64}[/tex] (which is 8), this value can be approximated as a number that is less than but very close to 8. I chose 7.9.
The expression becomes 6(7.9)+2π
Step 2: Approximate the value for 2π
Since π is approximately 3.14, 2π is approximately 6.28.
The expression becomes 6(7.9)+6.28
Step 3: Use order of operations
6(7.9)+6.28=47.4+6.28=53.68
b. Step 4: If allowed, use a calculator to check how close your approximation is to the actual value
[tex]6\sqrt{62} +2\pi =53.5272[/tex]
The approximation 53.68 is decently close to the actual value, so no minor math errors were made.
Answer:
54 and 53.53 see below
Step-by-step explanation:
Estimate the square root first. 7x7 = 49 and 8x8=64 so you can use 8 for your estimate. You can also estimate Pi as 3.
Now you have:
(6 x 8) + 2(3) which is 48 + 6 = 54
Using your calculator you get
47.244 + 6.283 = 53.53 rounded to the nearest hundredth
Using the slope formula, find the slope of the line through the given points.

Cup o’ Coffee buys its coffee for $1.25 a cup. The coffee shop then sells each cup for $3.75. What is the percent markup for a cup of coffee?
Answer:
47%
Step-by-step explanation:
.375 × .125 = .046875
rounding up, 5 keeps the 7 as is, 7 is greater than 5, therefore the 8, becomes a 9, 9 is greater than 5, so the 6 becomes a 7, .047.
move the decimal three digits to the left and you get, 47%.

Step-by-step explanation:
what is the first thing you draw in creating an angle bisector?
A) a curve intersecting both rays
B) a line segment intersecting both rays
on a coordinate grid what is the distance of (-2,4) and (5,4)
Answer:
the distance is 7 units
Step-by-step explanation:
Since the we calculate the distance between (-2,4) and (5,4) and those points have the same y=4 coordinate then they are both part of a horizontal line.
The distance is found by looking at the x-axis.
From -2 to 5 so is form -2 until 0 is (2 )+ (5 )more = 7
please help im confused
Hi there!
We are given two exterior angles. Don't panic! We know that exterior angles form a linear pair, which means they add up to 180 degrees.
180-130=50
180-96=84
Now that we have those angles, how can we work out the value of x?
Turns out that all the angles in any triangle add up to 180 degrees.
So
180-84-50=46 degrees.
So the value of x is 46 degrees.
Now let's work out the value of x in the next problem.
180-126=54
180-54-43=83 degrees
So the value of x in this problem is 83 degrees.
Let's move on to the third problem.
At first, it seems like we do not have enough information.
If we know that the right angle is 90 degrees (it is shown by a little square), then we have enough information.
180-90-43=47 degrees
So the value of x is 47 degrees.
Hope this helps you!

Step-by-step explanation:
The lowest common denominator of 10 and 6 is 30.
9/10 = 3*9/10*9 = 27/30
1/6 = 5/1/(6 * 5) = 5/30
6 27/30 - 5/30 = 6 22/30 = 6 11/15

A tablespoon is equivalent to about 4 teaspoons. A recipe calls for 2/3 cup of sugar for every 1/2 teaspoon vanilla. What is the unit rate in tablespoons
per cup?
Answer:
I understand the exercise is about unit rates, but why go out of the way to state false information? A tablespoon is exactly 3 teaspoons!
Anyway,
(1/2 tsp)/(2/3 cup) * (1tbsp)/(4tsp) = 1/2 * 3/2 * 1/4 = 3/16 tbsp/cup

There were 110 students at a creative writing workshop last year. This year there are 132 students. What is the percent of increase in the number of students at the workshop?
Answer:
20% increase
Step-by-step explanation:
the initial number is 110 so lets take that as a 100%
the final number is 132 and it will be x
110/132=100/x
we multiply the numerator of the first fraction with the denominator of the second fraction and vice versa.
110*x=132*100
110x=13200
x=120
Then we deduct 120 by 100 to know how much the percent increase is
(120-100)%=20% :)
Olympic National Park is 28.5 miles from Forks, Washington. it took the Pearce family 0.75 hours to drive there. What was their average speed, in miles per hour?
Answer:
38miles/hour
Step-by-step explanation:
Speed = Distance/Time
According to the question:
Time = 0.75hr
Distance = 28.5
Hence,
Speed = 28.5/0.75
= 38 miles/hr
