Step-by-step explanation:
Elena is making an open-top box by cutting squares out of the corners of a piece of paper that is 11 inches wide and 17 inches long, and then folding up the sides. If the side lengths of her square cutouts are inches, then the volume of the box is given by V(x)=x(11-2x)(17-2x)
Answer:
V(x) = (17 - 2x)(11 - 2x)x
Step-by-step explanation:
We are told that She is making an open top box. This means the box will have only 5 faces.
Now, she cuts squares out of the paper that measures 11 inches wide and 17 inches long.
Now, if the square side is x, it means the width of the box will be x. Since there are 2 upright faces that serve as width.
Thus, measurement of width from the 11 inches paper = (11 - 2x)
Now, similarly, there will be 2 upright sides that will serve as length. Thus, length from the 17 inches side is;
(17 - 2x)
Now,recall that a side of the square is x.
Thus, the depth is x.
Now, volume of a box is given by;
V = length x width x depth
Thus, in this case;
V(x) = (17 - 2x)(11 - 2x)x
A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?
Answer:
5 cents
Step-by-step explanation:
If bat + ball = 1.10 and the bat is a dollar more you know that the bat must cost at least 1 dollar. Divide the ten cents by two to split it evenly between the two and $1.05 is one dollar more than 5 cents
Olivia is making chocolate chip pancakes for breakfast. The recipe calls for 0.5 quart of milk and 2.5 cups of flour. When she checks her kitchen for ingredients she realizes she has 3 8 quart of milk and 18 8 cups of flour. Does she have the correct amount of milk and flour to make the pancakes from the recipe? Explain.
Given:
The recipe calls for 0.5 quart of milk and 2.5 cups of flour.
She has [tex]\dfrac{3}{8}[/tex] quart of milk and [tex]\dfrac{18}{8}[/tex] cups of flour.
To find:
Whether she have the correct amount of milk and flour to make the pancakes from the recipe.
Solution:
Required Milk = 0.5 quart
Milk she has = [tex]\dfrac{3}{8}=0.375[/tex] quarts
Clearly, 0.375 < 0.5.
Required Flour = 2.5 cups
Flour she has = [tex]\dfrac{18}{8}=2.25[/tex] cups
Clearly, 2.25 < 2.5
Since, the amount of milk and flour she has is less than the required amount, therefore she does not have the correct amount of milk and flour to make the pancakes from the recipe

Solve for x: −3|x + 7| = −12 (2 points)
A. x = 5 over 3 , x = − 19 over 3
B. x = −3, x = −11
C. x = −3, x = 11
Answer:
B. x = −3, x = −11
Step-by-step explanation:
−3|x + 7| = −12
-3x - 21 = -12 and -3x - 21 = 12
-3x - 21 = -12
-3x = 9
x = -3
-3x - 21 = 12
-3x = 33
x = -11
10. You want to be able to withdraw $30,000 each year for 25 years. Your account earns 8% interest. a. How much do you need in your account at the beginning? b. How much total money will you pull out of the account? c. How much of that money is interest?
Answer:
Kindly check explanation
Step-by-step explanation:
Given the following :
Rate (r) = 8% =. 0.08
Period (t) = 25 years
Yearly withdrawal = cashflow = P= $30,000
Using the present value formula (PV) :
Present Value (PV) = P[(1 - (1 + r)^-n) / r]
PV = 30000((1 - (1 + 0.08)^-25) / 0.08)
PV = $320,243.29
B.) Total amount pulled out :
Yearly withdrawal * number of years
$25000 * 25 = 625,000
C.)
Interest :
$625000 - $320,243.29 = $304,756.71

Determine whether cach point lies on the graph of the line y = 4.6x -7.
H(0, -7)
Answer:
Point H does lie on the graph y = 4.6x - 7
Step-by-step explanation:
Step 1: Define
y = 4.6x - 7
H(0, -7)
Step 2: Substitute, Evaluate, and Check
-7 = 4.6(0) - 7
-7 = 0 - 7
-7 = -7
Answer:
H(0,-7) does lie on the graph of line y = 4.6x - 7
Step-by-step explanation:
All you have to do is simply plug in the x and y values.
From the point H (0,-7) we can say that
x = 0
y = -7
Now just plug it into the equation.
y = 4.6x - 7
(-7) = 4.6(0) - 7
-7 = -7
Since -7 does equal -7, the point H is on the line of y = 4.6x - 7.
Larry is putting a row of rocks around his rectangular pool. Which descriptive model will tell him how many rocks he needs?
[2(pool length) + 2(pool width)] times the width of the rocks
(pool length times pool width) times the width of the rocks
(pool length times pool width) divided by the width of the rocks
[2(pool length) + 2(pool width)] divided by the width of the rocks
Answer:
P = [2( l)+2(w)] / width of the rock
Step-by-step explanation:
row of rocks around his rectangular pool, this tells us we are finding the perimeter
The perimeter of a rectangle is given by
P = 2( l+w)
P = 2( l)+2(w)
But we know that the length takes into account the width of the rock so divide each side by the width of the rock
P = [2( l)+2(w)] / width of the rock

equation
2x-1/4+x/3=2
Answer:
x=27/28
Step-by-step explanation:
Let's solve your equation step-by-step.
2x−14+x3=2
Step 1: Simplify both sides of the equation.
2x−14+x3=2
2x+−14+13x=2
(2x+13x)+(−14)=2(Combine Like Terms)
73x+−14=2
73x+−14=2
Step 2: Add 1/4 to both sides.
73x+−14+14=2+14
73x=94
Step 3: Multiply both sides by 3/7.
(37)*(73x)=(37)*(94)
x=27/28
Answer:
x=27/28

Gente pelo amor de Deus, qual é a responsta dessa questão: "Sendo a área de um retângulo fixado em 36cm². Observa-se na tabela a seguir, algumas possibilidades de medidas para o comprimento e sua respectiva largura.
Comprimento(c) | Largura (l)
18 | 2
12 | 3
9 | 4
6 | 6
Têm-se a que, neste caso, a sentença algébrica que relaciona o comprimento (c), em centímetros, com a largura (I) é:
A) c = 36/l
B) c = 45 + 15l
C) 36 = 2c + 2I
D) I = 36 - c
Answer:
A) c = 36/l
Step-by-step explanation:
A fórmula para a área de um retângulo é dada como Comprimento × Largura ou Comprimento × Respiração
A área do retângulo acima é fornecida como 36cm²
= 36cm² = Comprimento × Largura
36cm² = c × l
Portanto, a sentença algébrica que relaciona o comprimento (c), em correspondência, com a largura (I) é
c = 36 / l
Portanto, a resposta correta = opção A)

Isabella owns a rectangular lot with an area of 9/32 SQAURE mile. If the length of the western side of her lot is 3/4 mile, what is the length of the northern side?
Answer:
as below
Step-by-step explanation:
9/32=3/4 * y/x
becasue this is multiplication of fractions , its' not too tough to figure out 3 times what makes 9 and 4 times what makes 32
y=3
x=8
so the answer is 3/8 mile
The length of the northern side of a rectangular plot is 3/8 mile.
Here,
Area of rectangular lot = 9/32 square mile.
Length of the western side of lot = 3/4 mile.
We have to find the length of the northern side.
What is Area of rectangle?
The area of a rectangle is product of length and width.
Now,
Area of rectangular lot = 9/32 square mile.
Length of the western side of lot ( width ) = 3/4 mile.
Let the length of the northern side ( length ) = x mile
So,
Area of rectangle = length x width
[tex]\frac{9}{32} = x * \frac{3}{4} \\\\x = \frac{9}{32} *\frac{4}{3} \\\\x = \frac{3}{8}[/tex]
Hence, The length of the northern side of a rectangular plot is 3/8 mile.
