To make chocolate ice cream, you need about 3/8 pound of chocolate. How many pounds of chocolate will you need to make 4 batches of ice cream?
Answer:
1.5 pounds. it's simply 3/8 times 4
Answer:
1.5 pounds of chocolate
Step-by-step explanation:
A single batch of ice cream takes [tex]\frac{3}{8}[/tex] of a pound of chocolate. For every added batch, we add another [tex]\frac{3}{8}[/tex] pound, or multiply [tex]\frac{3}{8}[/tex] by the number of batches.
In this case, we are making 4 batches, so we need to multiply [tex]\frac{3}{8}[/tex] by 4.
[tex]4\cdot \frac{3}{8}[/tex]
[tex]\frac{4}{1}\cdot \frac{3}{8} =\frac{3}{2}[/tex]
[tex]\frac{3}{2}=1.5[/tex]
We need 1.5 pounds of chocolate to make 4 batches of ice cream.
Good luck ^^

Write a formula for the given measure. Let P represent the perimeter in inches, and w represent the width in inches. Identify which variable depends on which in the formula.
Complete Question:
Write a formula for the given measure. Let P represent the perimeter in inches, and w
represent the width in inches. Identify which variable depends on which in the formula.
*The perimeter of a rectangle with a length of 5 inches
Answer:
P = 2(5 + w)
Or
P = 20 + 2w
P is the dependent variable
w is the independent variable
P depends on w.
Step-by-step explanation:
Given:
Perimeter of rectangle = P
Width of the rectangle = w
Length of the rectangle = l = 5 in.
Formula for perimeter of a rectangle = 2(length + width)
Plug in the values. Formula for the given measure would be:
P = 2(5 + w)
Or
P = 20 + 2w
P is the independent variable, while w is the dependent variable.
This is because the Perimeter (P) of the rectangle is dependent on the width (w). Whatever value of w we get would determine the value of P were would get. Therefore,
P depends on w.

It moves in a straight line starting from rest. It travels with a constant acceleration for 3 seconds reaching a velocity of 4 m/s. Then it slows down with a constant deceleration of 0.5 m/s squared for 4 seconds before stopping what is the total distance travelled by the toy car?
Answer:
The total distance traveled by the toy car is 14 m
Step-by-step explanation:
Given;
initial velocity of the car, u = 0
final velocity of the car, v = 4 m/s
time of motion, t₁ = 3 s
constant deceleration of the car, -a = 0.5 m/s²
time of motion, t₂ = 4 s
The total distance traveled by the car, is the area of triangle ABC (check the image uploaded).
[tex]Total \ distance = Area = \frac{1}{2} |BC| \times H\\\\Total \ distance = \frac{1}{2} \times 4\times 7\\\\Total \ distance = 14 \ m[/tex]
Eight friends want to play enough games of chess to be sure everyone plays everyone else. How many games will they have to play?
The number of games, the friends have to play is an illustration of combination.
They have to play 28 games to ensure that they all play
Given
[tex]n = 8[/tex] --- number of friends
[tex]r = 2[/tex] --- only two friends can play at a time
For everyone else to play, we will make use of the following combination formula;
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^8C_2 = \frac{8!}{(8 - 2)!2!}[/tex]
[tex]^8C_2 = \frac{8!}{6!2!}[/tex]
Expand
[tex]^8C_2 = \frac{8 \times 7 \times 6!}{6! \times 2 \times 1}[/tex]
[tex]^8C_2 = \frac{8 \times 7}{2 \times 1}[/tex]
[tex]^8C_2 = 4 \times 7[/tex]
[tex]^8C_2 = 28[/tex]
Hence, the 8 friends have to play 28 games to ensure that everyone else plays

On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the way. Which decimal number shows the portion of the distance Sandy skips?
Answer:
0.2
Step-by-step explanation:
Convert the walking to percent
[tex]\frac{1}{2} \times 100 = 50[/tex]
Add both skateboarding and walking
[tex]30\% + 50\%\\\\= 30 + 50\\\\= 80[/tex]
Now, subtract that from a whole percent
[tex]100 - 80 = 20\\\\20\%[/tex]
Convert it to a decimal
[tex]20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2[/tex]
Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.
Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)
Answer:
(0, -4)
Step-by-step explanation:
The rectangular form is expressed as;
x = rcos theta
y = rsin theta
Given the coordinate (4, 3π/2)
r = 4
theta = 3π/2
Substitute
x = 4cos3π/2
x = 4cos270
x = 4(0)
x = 0
y= 4sin3π/2
y = 4sin270
y = 4(-1)
y = -4
Hence the required coordinate is (0, -4)

What is the value of x? (3x + 50) Enter your answer in the box (6x - 10) X =
Answer:
x = 20
Step-by-step explanation:
(6x - 10) and (3x + 50) are vertical angles and are congruent, then
6x - 10 = 3x + 50 ( subtract 3x from both sides )
3x - 10 = 50 ( add 10 to both sides )
3x = 60 ( divide both sides by 3 )
x = 20

Answer:
The answer is 72.9 !!!!

Trust I'm taking the same test.
Ryan runs a total of 94.5 miles over the course of 18 days.
What is speed?Speed is the ratio of the given distance and time.
It shows how fast an object is moving at a given time.
The formula is Distance / Time.
We can find the distance or time when the required values are given using this formula.
We have,
We can approach this problem by using arithmetic progression.
The first term is 1.5 miles, and the common difference is 0.3 miles.
So,
The nth term is given by:
an = a1 + (n-1)d
where a1 is the first term, d is the common difference, and n is the number of days.
We want to find the total distance Ryan runs over 18 days, which is the sum of the first 18 terms of the arithmetic progression:
S18 = (n/2) (a1 + an)
where n is the number of terms and a1 and an are the first and last terms, respectively.
Substituting the values we have:
a1 = 1.5 miles
d = 0.3 miles
n = 18
an = 1.5 + (18-1)0.3 = 6 miles
S18 = (18/2)(1.5 + 6) = 94.5 miles
Therefore,
Ryan runs a total of 94.5 miles over the course of 18 days.
