gabriel has 6 2/3 of almond flour to make macaroons. he plans to make a recipe that uses 3/4 of a cup of almond flour. what is the greatest number recipes he can make?
Answer:
8 cups max
Step-by-step explanation:
3/4 cup = 1 recipe
6 2/3(20/3) cup = 20/3 x 1
3/4
= 20 / 3
3 4
= 20 x 4
3 3
= 80/9
= 8 cups max
the 9th cup will not be enough.
What is the equation of the line through (4, -3) and (0, -2)?
A. y = 4x + 2
B. y=-4x - 2
C. y = -12- 2
D .y= 4x + 2
Whats the value of x? 3x - 5(x - 5) = -7 + 2x + 12
Answer:
x = 5
Step-by-step explanation:
Given
3x - 5(x - 5) = - 7 + 2x + 12 ← distribute and simplify left side
3x - 5x + 25 = 2x + 5
- 2x + 25 = 2x + 5 ( subtract 2x from both sides )
- 4x + 25 = 5 ( subtract 25 from both sides )
- 4x = - 20 ( divide both sides by - 4 )
x = 5

Sydney has a bag of stuffed animals containing, 1 elephant, 4 bears, 3 cats, and 2 dogs. If she randomly selects 1 stuffed animal from the bag, places it on her bed and then selects another animal. What is the probability that she chooses a bear both times?
Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15

The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Answer:
The total cost of the shopping trip is:
$82.08
Step-by-step explanation:
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off and the sales tax is 8%. What is the total cost of the shopping trip?
Step 1
We find the price after the discount
The Williams family goes shopping, and spend $95.00. They have a coupon for 20% off
Hence:
20% × $95
= $19
Therefore: $95 - $19
= $76
Step 2
We find the amount of sales tax
The sales tax is 8%
Hence:
8% of $76
= $6.08
Our sales tax = $6.08
Step 3
The total cost of the shopping trip is calculated as:
$76 + sales tax
= $76 + $6.08
= $82.08

Which expression in scientific notation is equivalent to (6×10^4)(3×10^5)
A 1.8×10^10
B 1.8×10^20
C 9×10^9
D 9×10^20
Answer: A) 1.8*10^10
Step-by-step explanation:
Multiply the constants together, and multiply the multiples of 10 together.
6*3 = 18
10^4 * 10^5 = 10^9
which gives you 18 * 10^9, but that isn't in scientific notation, because 18 isn't a number between 1 and 10
so you get 18 * 10 ^9
which is equal to 1.8*10^10

What is the number of possible permutations of 8 objects taken 4 at a time?
A.
24
B.
70
C.
1,680
D.
40,320
Answer:
1,680
Step-by-step explanation:
n!/(n-r)!
in this case n= 8 and r= 4
so 8!/(8-4)! = 1,680
The possible permutation of 8 objects taken at 4 a time will be 1680.
What is permutation?
The linear arrangement of the set of the orders or the linear arrangements of the numbers is called the permutation.
The number of possible permutations of 8 objects taken 4 at a time will be:-
[tex]^8C_4=\dfrac{8!}{(8-4)!}[/tex]
[tex]^8C_4=\dfrac{8!}{(4)!}[/tex]
[tex]^8C_4=\dfrac{8 \times 7\times 6\times 5\times 4\times 3\times 2}{4\times 3\times 2}=1680[/tex]
Therefore the possible permutation of 8 objects taken at 4 a time will be 1680.

There are 20 children in a class 45% are girls, How many girls and boys are there?
Answer:
Step-by-step explanation:
each person represents 5%. so 45% are girls. 45/5 is 9, so 9 are girls. 20 minus 9 is 11 so 9 girls and 11 boys
The number of girls is 9 and the number of boys is 11.
Important information:
Total number of students = 2045% of total students are girls.Percentage:Using the given information, the number of girls is:
[tex]20\times \frac{45}{100}=9[/tex]
Now, subtract the number of girls from the total number of students.
[tex]20-9=11[/tex]
Therefore, the number of girls is 9 and the number of boys is 11.

The bells are adding a new room to their house. The room will be a cube with volume 8,000 ft^3. They are going to put in hardwood floors, and the contractor charges $10 per square foot. How much will the hardwood floors cost?
Answer:
$4000
Step-by-step explanation:
Given that :
Volume of cube = 8000 ft³
Charge per ft² = $10
Recall, volume of a cube = a³
Where a = edge
Hence,
a³ = 8000
Take the cube root of both sides
a = 20
Hence,
Volume = 20 * 20 * 20
The Area of the floor will be :
20 * 20 = 400 ft²
If charge per ft² = $10
400 ft² = ($10 * 400) = $4000
this is harder so i put more points
Answer:
Sheet metal costs $20 per square foot.
Step-by-step explanation:
7.6x - 2.3x = 106
We are finding the value of x.
5.3x = 106
Divide both sides by 5.3.
x = 106 ÷ 5.3
x = 20
Answer and Explanation
__________________________________________________________
Sheet metal costs $20 per square foot( x = 20 )__________________________________________________________
Sheet metal costs 20 dollars per square foot, and we can figure this out by multiplying the 20 by the numbers and subtracting them.
__________________________________________________________
[tex]7.6x-2.3x=106[/tex] but what does x equal? ( 20 )
[tex]7.6\cdot20[/tex] = [tex]152[/tex]
[tex]2.3\cdot20[/tex] = [tex]46[/tex]
__________________________________________________________
[tex]152-46[/tex] = [tex]106[/tex]
Which is the same in the question, so x = 20.

A gyroscope of radius 18 centimeters rotates 35 times per minute. Find the linear velocity of a point on the edge of the gyroscope.
In one full rotation/revolution, a point on the edge travels a distance equal to the circumference of the gyroscope, or 2π (18 cm) = 36π cm. Convert the angular speed, 36π cm/rev, to linear speed:
(36π cm/rev) • (35 rev/min) = 1260π cm/min ≈ 3958 cm/min
HELP ME PLEASE!!!!!!!!!!!!!!!!!!!
[tex]distance = | \frac{2 - ( - 1)}{ \sqrt{ { (\frac{ - 1}{4} )}^{2} + {( - 1)}^{2} }} | \\ = \frac{1 2\sqrt{17} }{17} \\ = 2.9[/tex]
Mose decides to launch a rocket out of the barn at Schrute farms. The equation below represents the height (in meters), of the rocket getting launched above the ground, t seconds after the rocket is launched. h(t) = -.4 (t - 2)^2 + 5 How high above the ground is the rocket before it is launched?
Height at an instance of time is given by :
h(t) = -4( t - 2 )² + 5 .....1
Differentiating above equation with respect to t .
[tex]\dfrac{dh}{dt}= -4\times ( -2 ) ( t - 2 ) \\\\\dfrac{dh}{dt}= 8(t-2)[/tex]
Now, for maximum , [tex]\dfrac{dh}{dt} = 0[/tex] .
8( t - 2 ) = 0
t = 2
Putting value of t = 2 in given equation, we get :
h( 2 ) = -4( 2 - 2 )² + 5
h( 2 ) = 5 m
Therefore, maximum height rocket can reach is 5 m.
