Gabriella bought 50 lbs of clay for her art projects. She used 18.2 lbs to make a sculpture, and 0.76 lbs for each mug. How many mugs did Gabriella make if she had 18.88 lbs of clay left over?
Answer:
24 mugs
Step-by-step explanation: 18.88/0.76 = ≈24
Answer:
24 mugs
Step-by-step explanation:
Disregard unimportant information
Set up an equation
Variable x = number of mugs
18.88 = 0.76x
Divide both sides by 0.76 to isolate variable x
24.842...
There's no such thing as a fraction or decimal of a mug so round down to the nearest whole number

leroy is calculating the probability of rolling a regualr 6-sided die and flipping a coun. He wants to know the probability if rolling a 4, then landing on heads twice Find P(4 and H and H).
Answer:
To roll the 4 is 1/6 and landing heads twice is 1/4 and 1/6 x 1/4 and the probability of him doing that would be 0.04166666666% chance

please help with my geometry
Answer:
92.99
Step-by-step explanation:
Since this is a right triangle sine can be used to find the missing side. Sine should be used because you have the opposite and are trying to find the hypotenuse. So, following SOH-COH-TOA, the equation should be [tex]sin(34)=\frac{52}{x}[/tex]. Then, isolate x; once x is isolated the equation should be [tex]x=\frac{52}{sin(34)}[/tex]. Finally, plug that into a calculator to get ≈92.99116, which rounds to 92.99.

Answer: [tex]y=-\frac{3}{4}x+7[/tex]
Step-by-step explanation:
The slope is
[tex]\frac{4-7}{4-0}=-\frac{3}{4}[/tex]
Since the y-intercept is (0,7), the equation is [tex]y=-\frac{3}{4}x+7[/tex]

4. Which equation represents a linear function that has a slope of 5 and a y-intercept of -6?
O y=-6x+4/5
O y= 4/5x-6
O y=4/5x+6
O y = 6x+4/5
Answer:
y=5x-6
Step-by-step explanation:
Use form y= mx + b where m is the slope and b is the y intercept
The length of a living room is 3 feet more than its width. The area of the living room is 270 square feet. Write an equation that represents the area of the living room
Answer:
if the length is longer than width then it means its a rectangle...and equation of the area is length×breath ... therefore 270=x×3x

Answer:
[tex]\frac{(x + 1)(x - 2)}{x^{2} + 5}[/tex] This is the third option.
Step-by-step explanation:
Dividing a fraction is the same as multiplying the reciprocal of the second fraction.
[tex]\frac{x + 1}{x + 4}[/tex] × [tex]\frac{(x + 4)(x - 2)}{x^{2} + 5}[/tex]
[tex]\frac{(x + 1)(x + 4)(x - 2)}{(x + 4)(x^{2} + 5)}[/tex] Here, we can just get rid of the (x + 4) because it is common in both the numerator and denominator so they cancel each other out.
So the answer would be [tex]\frac{(x + 1)(x - 2)}{(x^{2} + 5)}[/tex] .
I hope this makes sense!! ^-^

The population of a certain city increased by 9000 people. Write a signed number to represent this population change.
Answer:
+ 9000
Step-by-step explanation:
Given that :
Population of city increased by 9000
This means that the a new populatuon is : initial population size + 9000
To. Represent increase or growth , we use the addition operator : '+'
Hence, a signed number representing population change is ; + 9000

Answer:
a. 5,040 ways
b. 210 ways
Step-by-step explanation:
a) We want to pick 4 numbers out of 10 given that orders matter
If orders do matter, it will be a permutation problem
Mathematically;
n P r = n!/(n-r)!
In this case, n is 10 and r is 4
Thus, we have it that;
10 P 4 = 10!/(10-4)! = 5,040
b) if orders do not matter
It will be a combination problem
n C r = n!/(n-r)!r!
n = 10 and r = 4
10 C 4 = 10! /(10-4)!4!
= 210
Please write the function(x) from the given rules:a. Twice the input value plus three. B. The input value minus five. C. To get the output, multiply the input by two, then add four.
Answer:
A) f(x) = 2x + 3
B) f(x) = x - 5
C) f(x) = 2x + 4
Step-by-step explanation:
To find - Please write the function(x) from the given rules:
A) Twice the input value plus three.
B) The input value minus five.
C) To get the output, multiply the input by two, then add four.
Proof -
Let us assume that the input = x
The output = f(x)
Now,
A)
f(x) = 2x + 3
B)
f(x) = x - 5
C)
f(x) = 2x + 4
Zane's bank charges him a fee for each day his account balance is less than $100. The arithmetic sequence {95.00, 89.50, 84.00, 78.50} describes Zane's bank balance for 4 days. Which explicit formula describes this arithmetic sequence?
There's 4 options/answers what is correct
1. an=95+(n-1)(5.50)
2. an=78.50+(n-1)(-5.50)
3 an=95+(n-1)(-5.50)
4. an= 5.50+(n-1)(-95)
Answer:
The correct option is;
3. aₙ = 95 + (n - 1)·(-95)
Step-by-step explanation:
From the question, we have;
The account balance below which a fee is charged = $100
The balance in Zane's bank account for the four days are;
95.00, 89.50, 84.00, 78.50
Therefore, we have the first term of the series, a = 95.00
The common difference are;
78.50 - 84.00 = -5.5
84.00 - 89.50 = -5.5
89.50 - 95.00 = -5.5
Therefore, the common difference is -5.5
The arithmetic sequence is therefore, aₙ = 95 + (n - 1)(-5.50)
Answer:
the answer is : an=95+(n-1)(-5.50)

Mia has a bag of jellybeans. She has 1 cherry, 1 lime, 8 grape, and 2 lemon jellybeans. If she pulls out 1 jellybean without looking, what is the probability that she pulls out a flavor other than grape?
Answer:
7.692
Step-by-step explanation:
have a nice day :D
Answer: 1/3 or .33
Step-by-step explanation:
If we have 12 jelly beans and there is 8 grape jelly beans and 4 other jelly beans that arent 8 you add the numbers and get a denominator of 12 then you add the number of jellybeans you are focusing on which equals 4/12 then we simplify 4/12 into 2/6 then 1/3 and then we have 1/3! Hope this helps have a great day!
Rachel is calculating the interest earned on a deposit of $350 in an account that earns 6% simple interest after 15 years.
I= prt
I=350(6)(15)
I=31,500
Rachel calculates the interest earned to be $31,500 as shown in her work above. Find the correct amount of interest earned.
Answer:
$315
Step-by-step explanation:
You are going to want to use the simple interest formula for this. The one below is modified for solving the interest earned.
I = interest amount
P = principal amount
r = interest rate (decimal form)
t = time
Now we can plug in the values into the equation:
This means that Rachel earned $315 worth of interest in the 15 year period.
Answer: $315
Step-by-step explanation:

A Formula for calculating displacement (distance from a point) is -
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
A) Calculate u when s = 120, a = 2 and t = 4
Answer:
s=ut +atsq/2
120=4u+4sq
4u=104
u=26m/sec
Answer:
26 m/s
Step-by-step explanation:
Given
[tex]s = ut + \frac{1}{2} {at}^{2} [/tex]
When a = 2 , s = 120 and t = 4
Then
[tex]120 = u \times 4 + \frac{1}{2} \times 2 \times {4}^{2} \\ 120 = 4u + 16 \\ 120 - 16 = 4u \\ 104 = 4u \\ u = \frac{104}{4} \\ u \: = 26
