A cubed aquarium tank holds 1,000 m^3 of water. How tall is the aquarium?

Answers

Answer:

10m

Step-by-step explanation:

formula to find volume of a cube is v=a ³

if the volume of the cube is 1000, then 1000=a³ (a being the length of an edge of the cube)(the edges of a cube are all the same length)

cube root of 1000 is 10

The required height of the cubed aquarium tank is 10 meters.


As given that, A cubed aquarium tank holds 1,000 m³ of water, the height of the aquarium is to be determined.

What is volume?

Volume is defined as the ratio of the mass of an object to its density.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
A cubed aquarium tank holds 1,000 m³ of water,
The volume of the cube = 1000
side ³ = 1000
side = ∛1000
side = 10

Thus, The required height of the cubed aquarium tank is 10 meters.

The classrooms in Okahurst School District are painted every summer. Seven gallons of paint are needed to paint 3 classrooms. How many more gallons are needed to paint the 129 classrooms at North High School than the 48 classrooms at Edgewater Elementary? Assume the situation is proportional

Answers

Answer:

189 Gallons

Step-by-step explanation:

7 gallons for 3 classrooms, so 7/3 for 1 classroom

multiply 7/3 * 129 to get 301 gallons at North High School

multiply 7/3 * 48 to get 112 gallons at Edgewater Elementary

301 - 112 = 189 gallons more at North High School than at Edgewater Elementary

Shayla wants to refinish the floors in her kitchen. Shayla predicts she will be able to cover the room with 75 square feet of tile flooring. Will shayla be able to cover the floor with 75 square feet of tile flooring?

Answers

Answer:

No

Step-by-step explanation:

Remember, she didn't take note of possible defects that may arise during actual construction, hence her prediction may be inaccurate.

Also, the 75 square feet mentioned is more likely based on approximations, and so it is best to think of possible deviation in the actual length of the room due to measurement error.

What is the value of x in the following equation?
4r +6
+ 3 = -6
-6
-3

Answers

Answer:

x = -6

Step-by-step explanation:

Solve for x:

(4 x + 6)/2 + 3 = -6

Hint: | Put the fractions in (4 x + 6)/2 + 3 over a common denominator.

Put each term in (4 x + 6)/2 + 3 over the common denominator 2: (4 x + 6)/2 + 3 = 6/2 + (4 x + 6)/2:

6/2 + (4 x + 6)/2 = -6

Hint: | Combine 6/2 + (4 x + 6)/2 into a single fraction.

6/2 + (4 x + 6)/2 = ((4 x + 6) + 6)/2:

(4 x + 6 + 6)/2 = -6

Hint: | Add the numbers in 4 x + 6 + 6 together.

Add like terms. 6 + 6 = 12:

(4 x + 12)/2 = -6

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 x + 12)/2 = -6 by 2:

(2 (4 x + 12))/2 = -6×2

Hint: | Cancel common terms in the numerator and denominator of (2 (4 x + 12))/2.

(2 (4 x + 12))/2 = 2/2×(4 x + 12) = 4 x + 12:

4 x + 12 = -6×2

Hint: | Multiply 2 and -6 together.

2 (-6) = -12:

4 x + 12 = -12

Hint: | Isolate terms with x to the left hand side.

Subtract 12 from both sides:

4 x + (12 - 12) = -12 - 12

Hint: | Look for the difference of two identical terms.

12 - 12 = 0:

4 x = -12 - 12

Hint: | Evaluate -12 - 12.

-12 - 12 = -24:

4 x = -24

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides of 4 x = -24 by 4:

(4 x)/4 = (-24)/4

Hint: | Any nonzero number divided by itself is one.

4/4 = 1:

x = (-24)/4

Hint: | Reduce (-24)/4 to lowest terms. Start by finding the GCD of -24 and 4.

The gcd of -24 and 4 is 4, so (-24)/4 = (4 (-6))/(4×1) = 4/4×-6 = -6:

Answer: x = -6

(1). [tex]h(t)=-4(t-1)^2+36[/tex]

(2). 1 minute

Step-by-step explanation:

They want you to factorize the equation in such a way that the vertex appears as a number in the equation; and you do that by using a method called completing the squareHere is our equation: [tex]h(t)=-4t^2+8t+32[/tex]We factor it by completing the square: But first remember this:A quadratic equation has the general form [tex]f(x)=ax^2+bx+c[/tex] Where a and b are the numbers before x squared and x respectively, and c is the number without an x, and f(x) is the value dependent on xIn this case x is tSo the steps are as followsEquate the equation to zero: [tex]-4t^2+8t+32=0[/tex] Divide each term by the (a) of the equation in this case is it -4, and we get: [tex]t^2-2t-8=0[/tex] Then take the new (c) to the other side of the equation, in the case we add 8 to both sides to get: [tex]t^2-2t=8[/tex] Now the tricky part, you have to add to both sides of the equation the square of half of the coefficient of t or number before t, not t squared just t and you get: [tex]t^2-2t+(-1)^2=8+(1)^2[/tex] Now the left side is in the square form, or it just means when you factor the left side, you get it as the square of a certain single term, in this case we get: [tex](t-1)^2=8+1[/tex] When we simplify we get: [tex](t-1)^2=9[/tex] Now any equation in this form, will give you the vertex when you equate the term in parenthesis to zero, and simplify: [tex]t-1=0,t=1[/tex] [tex]t=1[/tex] is the value of the t or time at the vertex To write the equation again, multiply every term with the (a) you used to get: [tex]h(t)=-4(t-1)^2+36[/tex] , and this is the equation for #(1)Now here is why we needed to get the vertex; the vertex tells us at what point the height either reaches its maximum/highest level, or where it reaches its minimum/lowest level So since the time (t) at the vertex is 1, in order to find the height at this time, just plug it into the equation:[tex]h(1)=-4((1)-1)^2+36\\h(1)=-4(0)+36\\h(1)=36[/tex] So that's the height at the vertexNow it can either be the maximum/highest height or the minimum/lowest height, in order to know this we check as followsRemember the (a) we used to factor the equation? -4, if the (a) value of a quadratic function is less than 0, then it is a maximum equation, mean whatever vertex you get will be the point where the equation reaches its biggest value.So at a height of 36 meters, and a time of 1 minute, the craft reaches its highest point.

at x = 10 .........> y = 0.01(2)¹⁰ = 10.24 .........> point is (10, 10.24)

Nancy is making accessories for the soccer team. She uses 877.76 inches of fabric on headbands for 30 players and 2 coaches. She also uses 263.70 inches of fabric on wristbands for just the players. How much fabric was used on a headband and wristband for each player? I am having trouble with this one.

Answers

Answer:

36. 22 inches

Step-by-step explanation:

Given that :

Head band fabric :

Total = 877.76 inches

Number of players = 30

Number of coaches = 2

Total number = (30 + 2) = 32

Head band Fabric per person :

877.76 / 32

= 27.43

Wristband fabric:

Total fabric used = 263.70

Number of players = 30

Wristband fabric per player :

263.70 / 30 = 8.79

Amount o fabric used on headband and Wristband for each player :

(27.43 + 8.79) = 36.22 inches of fabric per player

Step-by-step explanation:

The easiest way is turning both of these numbers into whole numbers by moving the decimal point to the right twice for both numbers. Now our equation will be....

376*1480

Now, we can solve this.

the answer to that equation is 556480.

Since we moved the decimal point to the right before, we have to move it to the left the same amount. Since we moved both of the numbers decimal point to the right twice, we add 2+2 to get 4 which means we have to move the decimal point to the left 4 times.

Eli was using a recipe for a large smoothie that required three and three–thirds bananas. Instead of making one smoothie, Eli decided to use the recipe to make three small smoothies. How many bananas will be required for each small smoothie? *

Answers

Answer:

three small smoothies require one and one-third bananas.

Step-by-step explanation:

Assuming that the three small smoothies are equal, and their sum equals the one large smoothie;

Number of bananas required for one large smoothie = three and three-third

three-thirds mean that out of three parts, three parts were selected. Therefore, three-thirds is the same thing as a whole or 1

∴ three and three-third  [tex]= 3 + \frac{3}{3} = 3 + 1 = 4[/tex]

Therefore, the one large smoothie required 4 bananas.

Large smoothie = 4 bananas

three small smoothies [tex]= \frac{4}{3} = 1 \frac{1}{3}[/tex]

Hence, three small smoothies require one and one-third bananas.
