Hi there :)
So since they initially drank 50 gallons, half of that is 25 gallons. 50+25= 75, therefore they drank 75 gallons.
Jada has 12 library books and 1/3 of that is 4, because 12 divided by 3 is 4, so 12-4=8. That means Han checked out only 8 books.
Good luck with the rest of your assignment, have a good day/night!!
Someone please help me with this thank you
A new ice skating rink will be approximately rectangular in shape and will have an area of 19,720 square feet. Using an equation for the perimeter P, of the skating rink in terms of its width W, what are the dimensions of the skating rink if the perimeter is 634 feet?
The dimensions of the rink are ? feet by ? feet.
Answer:
The dimension is: 232ft by 85ft
Step-by-step explanation:
Given
Shape: Rectangle
[tex]A = 19720[/tex] --- Area
[tex]P = 634[/tex] --- Perimeter
Required
Determine the dimension
Area is calculated as:
[tex]A = L * W[/tex]
This gives
[tex]19720 = L * W[/tex]
Perimeter is calculated as:
[tex]P = 2(L + W)[/tex]
This gives
[tex]634 = 2(L + W)[/tex]
Divide both sides by 2
[tex]317 = L + W[/tex]
Make L the subject
[tex]L = 317 -W[/tex]
Substitute 317 - W for L in [tex]19720 = L * W[/tex]
[tex]19720 = (317 - W)*W[/tex]
Open brackets
[tex]19720 = 317W - W^2[/tex]
Rewrite as:
[tex]W^2 - 317W + 19720 = 0[/tex]
Expand
[tex]W^2 -232W - 85W + 19720 = 0[/tex]
Factorize:
[tex]W(W -232) - 85(W - 232)= 0[/tex]
[tex](W - 85) (W - 232)= 0[/tex]
Split
[tex]W = 85\ or\ W = 232[/tex]
Recall that:
[tex]L = 317 -W[/tex]
[tex]L= 317 - 85\ or\ L = 317 - 232[/tex]
[tex]L= 232\ or\ L = 85[/tex]
Hence, the dimension is: 232ft by 85ft
The dimension of the rectangular rink is 85ft by 232ft
Perimeter and Areas of triangleGiven the following parameters
Area = 19,720 square feet.Perimeter = 634 feetThe formula for finding the area is:
A = lw
lw = 19,720
l = 19,720/w
If the perimeter is 634 feet
2(l+w) = 634
2(19,720/w + w) = 634
39,440/w + 2w = 634
39,440 + 2w^2 = 634w
2w^2 - 634w + 39,440 = 0
On factorizing, w=85 or w=232
Since l = 19,720/w
l = 19,720/232
l = 85
Hence the dimension of the rectangular rink is 85ft by 232ft

The order of transformations in a sequence matters; reversing the order will not necessarily give the same image. Is this statement True of False?
Answer:
False
If the transformations include a reflection, then the orientation will change. A translation or rotation will preserve the original orientation

A water container is in the form of a rectangular tank. Its base is 20 cm by 17 cm and depth of the water in the
container is 28 cm. Tony adds one a quarter litres, 350 ml and 100 ml water to the container
Calculate by how many centimeters has the level of water in the tank risen.
Answer:
[tex]Height= 5cm[/tex]
Step-by-step explanation:
Given
Tank:
[tex]Base =20cm\ by\ 17cm[/tex]
[tex]Depth = 28cm[/tex]
Water:
[tex]Quantity = 1\frac{1}{4}L, 350mL, 100mL[/tex]
Required
Determine [tex]the\ height[/tex] of the water in the tank
First, we calculate the total volume of water added.
[tex]Quantity = 1\frac{1}{4}L+ 350mL + 100mL[/tex]
[tex]Quantity = 1.25L+ 350mL + 100mL[/tex]
Convert all units to Litres
[tex]Quantity = 1.25L+ 0.35L + 0.1L[/tex]
[tex]Quantity = 1.7L[/tex]
Convert to cm^3
[tex]Quantity = 1.7 * 1000cm^3[/tex]
[tex]Quantity = 1700cm^3[/tex]
The volume of the water in the tank is calculated as:
[tex]Volume =Base\ Area * Height[/tex]
i.e. the base area of the tank multiplied by the height of the water in the tank
[tex]Volume =20cm * 17cm* Height[/tex]
[tex]Volume =340cm^2* Height[/tex]
Since the above represents the quantity of water, we can substitute 1700cm^3 for Volume
[tex]1700cm^3=340cm^2* Height[/tex]
Make height the subject
[tex]Height= \frac{1700cm^3}{340cm^2}[/tex]
[tex]Height= \frac{1700cm}{340}[/tex]
[tex]Height= 5cm[/tex]

Answer:
136
Step-by-step explanation:
[tex]2+\sqrt{x+8} =14\\\sqrt{x+8} =12\\x+8=144\\x=136[/tex]
Answer:
2+ x+8 =14
Subtract 2 from both sides of the equation.
x+8 +2−2=14−2
Subtracting 2 from itself leaves 0.
x+8 =14−2
Subtract 2 from 14.
x+8 =12
Square both sides of the equation.
x+8=144
Subtract 8 from both sides of the equation.
x+8−8=144−8
Subtracting 8 from itself leaves 0.
x=144−8
Subtract 8 from 144.
x=136

Diego scored nine points less than Andre in the basketball team Noah scored twice as many points as Diego if Noah scored 10 points how many ponts did Andre score
Answer:
1..........................
Answer:
Andre scored 14 points.
Step-by-step explanation:
set up expressions with the info given:
Diego's points: a –9
Andre's points: 2d. and
n = 2d
Noah's points = 10
Use the expressions to set up equations to solve.
To find a, Andre's points, we can work backwards.
Substitute the 10 from the last expression for n in the equation n=2d, and solve for d:
10 = 2d. Divide both sides by 2
5 = d
Substitute the value of d, Diego's points, to make an equation using the first expression:
5 = a –9 Add 9 to both sides.
5 + 9 = a a = 14
Andre scored 14 points
What is the value of the expression (2)^6?
pls help
Answer:
64
Step-by-step explanation:
2^6, or 2⁶, is two to the power of six.
Basically you multiply the bottom number (in this case 2) by itself as many times as the the number in the top right (in this case six)
2^6=2*2*2*2*2*2=64
Answer: 64
Step-by-step explanation:
2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 ⋅ 2 = 64
2 ⋅ 2 ⋅ 2 = 8
2 ⋅ 2 ⋅ 2 = 8
8 x 8 = 64
Jason took out an 800$ loan from his bank two years ago. He recently paid 860$ Back to the bank. This included the original loan amount and the simple interest charged to him. What was the annual interest rate of Jason’s loan
Answer:
3.75%
Step-by-step explanation:
Principal , P= $800
Number of years, t = 2
Total Amount paid back(principal + simple interest) , A = $860
To obtain the interest rate on the loan :
We use the Relation :
A = P(1 + rt)
r = interest rate
860 = 800(1 + 2r)
860 / 800 = 1 + 2r
1.075 = 1 + 2r
1.075 - 1 = 2r
0.075 = 2r
r = 0.075 / 2
r = 0.0375
Hence, interest rate on loan = 0.0375 = (0.0375 * 100%) = 3.75%

Answer:
f(-3)= -8
f(2) = 4
Step-by-step explanation:
The first equation x ≤ 0 means that if the variable x, or in our case, -3, is less than or equal to 0, the answer will be calculated into the equation.
3(-3) + 1 = -8
The bottom equation x ≥ 2 means that if the variable, x, or in our case, 2 is more than or equal to 2, the answer is 4. Since 2 is equal to 2, the answer would then be 4.

Tara has a plastic string that is 3 3/4 feet long. She will cut the string to make bracelets that are each 5/8 foot long. Explain how to use the number line to determine the maxium number of braceletss tara can make
Answer:
The answer is below
Step-by-step explanation:
Given that the length of the plastic string is 3 3/4 feet = 15 / 4 feet.
Bracelets of 5/8 foot long is needed to be made. To determine the maximum number of bracelets that can be made; using the number line, 5/8 is subtracted repeated times from 15/4.
We can see that when 5/8 is subtracted 6 times from 15/4, the result is 0.
15/4 ÷ 5/8 = 6
Hence Tara can make 6 bracelets from the plastic sting.

I'll give brainliest for the first and correct answer! The perimeter of a triangle is 135. The sides have lengths a, b, and c. The ratio of a to b is 3:5 and the ratio of a to c is 6:11. Find the length of each side of the triangle.
9514 1404 393
Answer:
(a, b, c) = (30, 50, 55)
Step-by-step explanation:
If we rewrite the ratio of A to B so it has the same number of ratio units as in the ratio of A to C, we have ...
A : B = 3 : 5 = 6 : 10
A : C = 6 : 11
so ...
A : B : C = 6 : 10 : 11
The total number of ratio units is 27. They stand for 135 real units, so each one stands for 135/27 = 5 real units.
Multiplying the last ratio statement by 5, we find the lengths of each of the sides.
A : B : C = 6 : 10 : 11 = 30 : 50 : 55
The side lengths are (a, b, c) = (30, 50, 55).

A length of a rectangle is 16/9,. and its width is 3/4 of its length. Find the area of this rectangle
Answer:
The answer is 1 1/3
Step-by-step explanation:
First you multiply the numerators then the denominators.
16 x 3 =48 , 9x4=36 =48/36. So that is your answer but it can still be simplified.
They can both be divided by 12 . 48 divided by 12 = 4 . 36 divided by 12 = 3.
but 4/3 is an improper fraction so you divide 4 by 3 and you get 1 with a remainder 1 = 1 and 1/3
