Answer: 6.3 m

Step-by-step explanation:

"8% more" = 1.08 (which is 1+0.08). "10% less" = 0.90 (which is 1-0.10).

first = 5.25

her_best = 1.08*first

her_best = 0.90*winning

Substitute to determine the winning jump's length.

winning = 1.08*5.25/0.90 = 6.3

So, the winning jump was 6.3 meters.

Answer:

[tex] \boxed{n = 8} [/tex]

Step-by-step explanation:

[tex] = > 9n - 7 = 3 + 8n - 2 \\ \\ = > 9n - 7 = 8n + 3 - 2 \\ \\ = > 9n - 8n = 1 + 7 \\ \\ = > n = 8[/tex]

Answer:

8

Step-by-step explanation:

9n - 7 = 3 + 8n - 2

Combine like factors.

9n - 7 = 8n + 1

Subtract 8n from both sides

n - 7 = 1

Add 7 to both sides.

n = 8

Answer:

What is the lowest common denominator?

✔ 6

Rewrite the difference as a sum of the fractions using the lowest common denominator.

✔ 5/6 + (–4/6)

What is the answer?

✔ 1/6

Step-by-step explanation:

Fractions can be combined by taking their LCMs

The numbers are given as:

[tex]\mathbf{\frac{2}{3}\ and\ \frac{5}{6}}[/tex]

The denominators are 3 and 6.

Factor both numbers;

[tex]\mathbf{3 = 1\times 3}[/tex]

[tex]\mathbf{6 = 1 \times 2 \times 3}[/tex]

So, the LCM is:

[tex]\mathbf{LCM = 1 \times 2 \times 3}[/tex]

[tex]\mathbf{LCM = 6}[/tex]

The lowest common denominator is 6

The expression is represented as:

[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6}}[/tex]

Rewrite as:

[tex]\mathbf{ - \frac{2}{3}\ + \ \frac{5}{6} = -\frac{4}{6} + \frac{5}{6}}[/tex]

Hence, the new expression is [tex]\mathbf{-\frac{4}{6} + \frac{5}{6}}[/tex]

Answer:

Total interest in 1 year = $2,250

Step-by-step explanation:

Given:

Rate of simple interest = 3% = 0.03

Amount of investment = $25,000

Number of investment = 3

Find:

Total interest in 1 year .

Computation:

Simple interest = Amount of investment × Rate of simple interest

Simple interest = $25,000 × 0.03

Simple interest = $750

Total interest in 1 year = Simple interest × Number of investment

Total interest in 1 year = $750 × 3

Total interest in 1 year = $2,250

Answer: D also, can i have brainliest?

solution:

The other 2 sides added have to be greater than 13

Option A: 5 + 8 = 13. 13 is not greater than 13 so it's not the answer.

B: 6 + 7 = 13. Same thing as option A

C: 7 + 2 = 9. 9 is less than 13 so not the answer.

D: 8 + 8 = 16. 16 is greater than 13 so D is the correct answer.

Answer:

4y = -7-2x

y = -7-2x/4

now give suitable value for x (Example 3)

Answer:

[tex]y=-\frac{1}{2} x-\frac{7}{4}[/tex]

Step-by-step explanation:

[tex]4y+2x=-7[/tex]

Subtract [tex]2x[/tex] from both sides of the equation.

[tex]4y+2x-2x=-7-2x[/tex]

[tex]4y=-7-2x[/tex]

Divide by 4 on both sides of the equation.

[tex]\frac{4y}{4} =\frac{-7-2x}{4}[/tex]

[tex]y=\frac{-2x-7}{4}[/tex]

Simplify the equation.

Answer:

Locate the ordered pair (0, –6). From that point on the graph, move up 2, right 1 to locate the next ordered pair on the line. Draw a line through the two points.

Step-by-step explanation:

The answer is the first one because the slope is technically [tex]\frac{2}{1}[/tex]

Up 2 over 1

Since the slope is positive, the graph goes to the right.

(0, -6) is the y intercept because it intersects the y - axis.

Then you draw those two points and connect them.

Answer:

Step-by-step explanation:

by making the length an inequality x height will be 1.5x

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96cm

The height of the square pyramid is equal to 24.96 cm.

A square pyramid in geometry is a pyramid with a square base. A right square pyramid is one in which the peak is perpendicular to and above the square's centre.

Given that the height of a square pyramid is one-half the length of each side. The volume of the pyramid is 2,304 cubic inches.

The height of the square pyramid will be calculated as,

Volume=1/3BA xh

X×X×1.5X 1/3=2304

0.5x3=2304

X³=2304÷0.5

X³=4608

X=³√4608

X=16.64cm

H=16.64x1.5=24.96 cm

Therefore, the height of the square pyramid is equal to 24.96 cm.

#SPJ2

Answer:

18.2 cubic meters.

Step-by-step explanation:

From the measurements they give us, we assume that the shed has the shape of a rectangular prism, however, to calculate the amount of storage, we must calculate the volume.

The volume would be:

V = height * width * length

According to the statement height = 2, width = 2 and length = 3.25

V = 2 * 2 * 3.25

V = 13

That is, the volume of the shed is 13 cubic meters, but then they mention that the roof line to the peak is 0.8 meters high, which means that the volume can increase, the new volume would be changing the height = 2 + 0.8 = 2.8, the other values remain the same:

V = 2.8 * 2 * 3.25

V = 18.2

That is to say that when adding that part, the volume that is to say total amount of storage is 18.2 cubic meters.

Answer:

The slope of the line through the points is -5/7

Step-by-step explanation:

Here, we want to calculate the value of the slope through the lines

Mathematically;

m = y2-y1/(x2-x1)

Where (x1,y1) = (-4,2)

and (x2,y2) = (3,-3)

Substituting these values, we have;

m = (-3-2)/(3-(-4)) = -5/7 = -5/7

The slope of the line through (-4, 2) and (3, -3) is; -5/7

According to the question;

The slope, m of the line is given mathematically as;

Therefore, in this case;

Slope, m = -5/7

Answer:

6 teaspoons

Step-by-step explanation:

2 teaspoons = 1/3 tsp of salt

6 teaspoons = 1 tsp of salt

This was done by multiplying 2 by 3 since 3 thirds (3/3) make one whole.

So if 2 teaspoons are used for 1/3 teaspoon of salt, 4 teaspoons would be used for 2/3 teaspoon of salt and 6 teaspoons would be used for 1 teaspoon of salt.

Step-by-step explanation:

Answer:

i. x = -0.5 and 1.5; ii. x = 1.5

Step-by-step explanation:

For part i, we can take a look at the x-intercepts of the parabola. When a quadratic equation equals 0, this means that we are taking a look at its roots, or solutions.

The parabola intersects the x-axis at approximately -0.5 and 1.5. We can say this is an estimate to the solutions.

For part ii, the question is asking the x value that makes the function equal 2. We just look at the point where y = 2, which happens to be 1.5. So when x = 1.5, y = 2, which is what we want.

Answer:

Step-by-step explanation:

Your answer for  x = 25.35 is correct.

Since the night must be an integer, you need to take 26 as your final answer. b) for y = 1500, you solve for x to consider which one is better.

for plan A, y = 87 x + 2129, you have to pay $2129 before starting the trip, hence $1500 is NOT enough to pay.

for plan B, y = 171x and y = 1500, hence x = 8.77. So, with $1500 you can travel for 8 nights.
