Step-by-step explanation:
Gabriel has 15 ⅝ pounds of clay. He will use 7/10 pound to make each bowl. After making 8 bowls, Gabriel wonders how many more bowls he can make. How many more bowls can how make?
Answer:
14
Step-by-step explanation:
The total amount of bowls he can make given the pounds of clay and the pound needed to make a bowl = [tex]15\frac{5}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ÷ [tex]\frac{7}{10}[/tex]
= [tex]\frac{125}{8}[/tex] ×[tex]\frac{10}{7}[/tex] = 22.32
Number of bowls he can more more = total amount of bowls that can be made - number of bowls already made
22.32 - 8 = 14.32 bowls
Rounding off to the nearest whole number gives 14
Someone please help me with this question
You are organizing a school banquet. You spend $82 on decorations. Dinner will cost $13 for each person that attends. In the equation y=13x+82, y is the total cost of the banquet for x people. Complete the solution (69,?) to find the cost for 69 people.
Answer:
(69,979)
Step-by-step explanation:
In the coordinates, x is represented as 69. We can now insert this into the equation.
y = 13x + 82
Now to insert x.
y = 13(69) + 82
Now we can multiply 13 by 69.
13*69 = 897
Now fix the equation.
y = 897 + 82
Now add to get our y.
897 + 82 = 979
Substitute into the equation.
y = 979
And there is our answer. We now need to put this into the coordinates.
And we get our final answer of (69,979).
Hope this helps. Have a nice day.
YO 10 or 22 points can somebody pls help me I’m stuck. Solve each inequality for x then graph your answer on a number line. Remember when you divide by a negative you have to switch the inequality symbol. Pls pls help me :(
Answer:
x<5
Step-by-step explanation:
−2(x−7)>4
Step 1: Simplify both sides of the inequality.
−2x+14>4
Step 2: Subtract 14 from both sides.
−2x+14−14>4−14
−2x>−10
Step 3: Divide both sides by -2.
−2x ÷ −2 > −10 ÷ −2
x<5

Which of these are characteristics of reptiles? Check all that apply. They undergo internal fertilization. Their urine is concentrated. They use their skin for gas exchange. They have two-chambered hearts. They are covered in scales.
Answer:
Answers Below. Have a wonderful day!
Step-by-step explanation:
They undergo internal fertilization: True Most reptiles undergo internal fertilization sexually when the sperm of a male reptile enters the cloaca of female reptiles, fertilizing the egg.
Their urine is concentrated: False Reptiles do not have the ability to produce liquid urine that is more concentrated than their own body fluid because they lack a structure in their nephron called the Loop of Henle.
They use their skin for gas exchange: False They cannot use their skin as an organ of gas exchange. Reptiles depend entirely on their lungs for this.
They have two-chambered hearts: False They have three-chambered hearts.
They are covered in scales: True All reptiles are covered in scales (snakes, lizards, turtles, etc.)

2{x+8}+5{x-1}=60 answer
Answer:
x=7
Step-by-step explanation:
2{x+8}+5{x-1}=60
Distribute
2x+16+5x-5 = 60
Combine like terms
7x +11 = 60
Subtract 11 from each side
7x+11-11 = 60-11
7x = 49
Divide each side by 7
7x/7 = 49/7
x = 7
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After years of paying monthly payments of $562.88. , he finally paid off the loan.
Answer:
hello your question is incomplete below is the complete question
To purchase $14,500 worth of restaurant equipment for his business, Hans made a down payment of $1800 and took out a business loan for the rest. After 2 years of paying monthly payments of $562.88. , he finally paid off the loan. What was the total amount Dean ended up paying for the equipment ( including the down payment and monthly payments )
answer: $15309.12
Step-by-step explanation:
Initial cost of equipment = $14500
Down payment = $1800
cost of equipment = 14500 - 1800 = $12700
Monthly payment = $562.88
Therefore payment made after 2 years = ( 562.88 * 24 ) = $13509.12
Total amount paid by Dean for the equipment
= down payment + monthly payments
= $1800 + $13509.12
= $15309.12

Answer:
No, No, Yes, Yes
Step-by-step explanation:
We can simply substitute the pairs as x and y in the equation:
(5, 0)
7*5 + 5*0 = 35 + 0 = 35
[tex]35 \ne 9[/tex]
(-4, -3)
7*(-4) + 5*(-3) = -28 - 15 = -43
[tex]-43 \ne 9[/tex]
(2, -1)
7*2 + 5*(-1) = 14 - 5 = 9
[tex]9 =9[/tex]
(-3, 6)
7*(-3) + 5*6 = -21 + 30 = 9
[tex]9 = 9[/tex]
what's the domain and range function for y=(x-12)^2+11
Answer:y = x 2 − 12 x The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. Interval Notation: ( − ∞ , ∞ ) Set-Builder Notation: { x | x ∈ R } The range is the set of all valid y values. Use the graph to find the range. Interval Notation: [ − 36 , ∞ ) Set-Builder Notation: { y | y ≥ − 36 } Determine the domain and range. Domain: ( − ∞ , ∞ ) , { x | x ∈ R } Range: [ − 36 , ∞ ) , { y | y ≥ − 36 }
Step-by-step explanation:
Answer:
Step-by-step explanation:
There is no restriction upon x so the domain is all real numbers
x=(-oo, +oo)
y has a minimum value when x=12 and y=11. Any other value of x increases the value of y. So the range is all real numbers greater than or equal to 11.
y=[11, +oo)
Factor completely: 2x^3-12x^2+18x
Answer:
2x(x - 3)²
Step-by-step explanation:
We can simplify this a lot by first factoring 2x out of each term:
2x³ - 12x² + 18x
= 2x(x² - 6 + 9)
We can then factor the trinomial fairly easily, as it's a perfect square:
= 2x(x - 3)²

What would be the SUM of the lengths of the first and second diagonals rounded to the nearest whole number?
Answer:
16 m
Step-by-step explanation:
Use Pythagorean theorem,
hypotenuse² = base² +altitude²
= 5² +6²
= 25 + 36
= 61
First diagonal = [tex]\sqrt{61}[/tex] = 7.81 m
Second diagonal² = first diagonal² + altitude²
= [tex](\sqrt{61})^{2}[/tex] + 3²
= 61 + 9
= 70
second diagonal = [tex]\sqrt{70}[/tex] = 8.37 m
First diagonal + second diagonal = 7.80 + 8.37 = 16.17 = 16

Step-by-step explanation:
Lannister checks out 6 sets of book
Each set had the same number of books
She reads 7 books and has 11 more to go
Therefore the number of books in each set can be calculated as follows
= 11+7
= 18
18/6
= 3
Hence there are 3 books in each set

Answer:
43x+39
Step-by-step explanation:
(5)(9x)+(5)(6)+−2x+9
=45x+30+−2x+9
=45x+30+−2x+9
=(45x+−2x)+(30+9)
=43x+39
(if this helps please give brainliest and 5 stars thanks)
Answer:
43x + 39
Step-by-step explanation:
5 ( 9x + 6 ) - 2x + 9
Firstly, open up the brackets.
= 45x + 30 - 2x + 9
Now bring the like term together and simplify.
=45x - 2x + 30 + 9
= 43x + 39
5. The value of a home increases by 7% each year. Explain why the value of the home doubles approximately once each decade.
Answer:
Step-by-step explanation:
2x=x(1.07)^t
2=(1.07)^t
t=log2/(log 1.07) ≈10.2 4 years
so it doubles in approximately in 10.2 years
To solve the problem we must know about Compounding.
What is compounding?Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
[tex]A = P(1+r)^t[/tex]
where A is the value after t period of time,
P is the value of the asset at the beginning, and,
r is the rate of interest.
The value of the home doubles once each decade.
Given to us
As it is given that the value of a home increases by 7% each year, therefore, the value of the home is compounding every year.
We know the formula of compounding,
[tex]A = P(1+r)^t[/tex]
Why does the value doubles?Now, let's assume a house whose value is 'P' today, therefore, substitute the value of the house in the formula of compounding,
[tex]A = P(1+r)^t[/tex]
Substitute the rate at which the value is increasing,
[tex]A = P(1+0.07)^t[/tex]
We know that in a decade there are 10 years,
[tex]A = P(1.07)^{10}[/tex]
[tex]A = 1.967P\approx 2P[/tex]
As we can see that the value of the home is almost 2 times the 'P' therefore, twice the value of the home at the beginning.
Hence, the value of the home doubles once each decade.
