12 steps for this problem.

Step-by-step explanation:

We have been given that Judi is making a rope ladder. She uses 1/2 yard of rope for each step.

Since Judi makes each step of ladder with 1/2 yard of rope, so one yard of rope will make two steps.

Therefore, Judi can make 12 steps of ladder from 6 yards of rope.

3s+2j=95

s+j=40

Step-by-step explanation:

We need to create equations for both statements.

s=shirts j=jeans

(s & j can be replaced by any letter i just used s and j to avoid further confusion)

3s+2j=95

s+j=40

If you need me to solve it i can do that too but it seems you just need the equations

Answer: $10.50

Step-by-step explanation:

Here is the complete question:

Mr. Frye distributed $126 equally among his 4 children for their weekly allowance. John, the oldest child, paid his siblings to do his chores. If John pays his allowance equally to his brother and two sisters, how much money will each of his siblings have received in all?

Amount distributed = $126

Number of children = 4

Each child gets = $126/4 = $31.5

If John pays his allowance equally to his brother and two sisters, the amount that each sibling will get will be:

= $31.5 / 3

= $10.50

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

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.

Answer:  (a) 6760000

(b) 5760000

Step-by-step explanation:

Total letters in English alphabet = 26

Total digits = 10

Given: Each automobile license plate number consists of two letters followed by a four-digit.

(a) If there are no restrictions, then the total number of license plates formed = 26 x 26 x 10 x 10 x 10 x 10

= 6760000

(b) if the letters O and I are not used, total letters can be used ]= 26-2=24

Then the total number of license plates formed = 24 x 24 x 10 x 10 x 10 x 10

=5760000

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.

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

Answer:

1.275

Explanation:

The given equation is:

f(x) = 0.01(2)ˣ

We want to find the rate of change from 2 to 10 which means that we need to find the slope from 2 to 10.

We start by getting the y-values for each of the given x-values:

at x = 2 ..........> y = 0.01(2)² = 0.04 ...........> point is (2, 0.04)

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

Now, we get the slope as follows:

slope =

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

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

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.

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

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.

Answer:

55.648

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.

Our final answer : 55.648
