sarah competes in a long jump competion. her first jump is 4.25m. her best jump is 12% more than this. however, her best jump is 15% lower than the winning jump. work out the of the winning jump.

Answers

Answer 1

The winning jump is approximately 5.60 meters.

1. We start by denoting Sarah's first jump distance as [tex]\( x \)[/tex] meters.

2. We calculate Sarah's best jump distance, which is 12% more than her first jump, giving [tex]\( 1.12x \).[/tex]

3. We know Sarah's best jump is 15% lower than the winning jump, so we set up an equation equating her best jump to 0.85 times the winning jump.

4. Solving for the winning jump, we find [tex]\( \frac{1.12x}{0.85} \).[/tex]

5. Substituting the value of Sarah's first jump [tex](\( x = 4.25 \))[/tex], we find that the winning jump is approximately 5.60 meters.

Let's denote Sarah's first jump distance as [tex]\( x \)[/tex] meters.

According to the problem:

- Sarah's best jump is 12% more than her first jump: [tex]\( 1.12x \).[/tex]

- Sarah's best jump is 15% lower than the winning jump.

Let's calculate Sarah's best jump distance:

[tex]\[ \text{Best jump} = 1.12x \][/tex]

Now, let's find the winning jump distance:

[tex]\[ \text{Best jump} = 0.85 \times \text{Winning jump} \][/tex]

Since Sarah's best jump equals 0.85 times the winning jump:

[tex]\[ 1.12x = 0.85 \times \text{Winning jump} \][/tex]

To find the winning jump distance, we'll divide Sarah's best jump by 0.85:

[tex]\[ \text{Winning jump} = \frac{1.12x}{0.85} \][/tex]

Now, let's substitute the value of Sarah's first jump:

[tex]\[ \text{Winning jump} = \frac{1.12 \times 4.25}{0.85} \][/tex]

[tex]\[ \text{Winning jump} = \frac{4.76}{0.85} \][/tex]

[tex]\[ \text{Winning jump} \approx \frac{4.76}{0.85} \][/tex]

[tex]\[ \text{Winning jump} \approx 5.60 \][/tex]

So, the winning jump is approximately 5.60 meters.

Complete question

sarah competes in a long jump competion. her first jump is 4.25m. her best jump is 12% more than this. however, her best jump is 15% lower than the winning jump. work out the of the winning jump.

What is the perimeter of the triangle shown on the coordinate plane, to the nearest tenth of a unit?

14.6 units
15.5 units
21.0 units
21.6 units

Answers

To calculate the perimeter, consider each side separately.

Right side: This is easiest since it's a vertical line - it's 7 units long.

Top side: If you look carefully, this side is really the hypotenuse of a triangle that is 1 unit tall and 6 units long. Using the Pythagorean Theorem, you can calculate the length of the hypotenuse to be 1^2 + 6^2 = c^2 --> c = 6.1

Left side: just like the top side, this side is the hypotenuse of a triangle that is 6 units tall and 6 units long. Pythagoras again: 6^2 + 6^2 = c^2 --> c = 8.5

Add these three numbers to get the perimeter: 7 + 6.1 + 8.5 = 21.6

One car rental company charges $30 per day plus $0.25 per mile driven. a car company charges $40 per day plus $0.10 per mile driven. how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company? write an inequality to solve.

Answers

Rewrite the question into equations:
let's say x is the miles you drive for a day
the first company's rental charge= $30+$0.25x
the second company's rental charge= $40+$0.10x

Calculate what the x is when two equations are equal to each other:
$30+$0.25x=$40+$0.10x
$0.25x-$0.10x=$40-$30
$0.15x=$10
x=$10/$0.15
x=66.667 miles

at least 66.667 miles. I am not sure though. I'm a little bit tired today, so you might want to check it yourself.

Answer:

66.667 miles

Step-by-step explanation:

Given: One car rental company charges $30 per day plus $0.25 per mile driven.

Second car company charges $40 per day plus $0.10 per mile driven.

To find:  how many miles must you drive for a one-day rental at the second company to be less expensive than the same rental at the first company?

Solution: Let the distance driven on a day be x miles.

As per question,

The first rental company will charge [tex]=30+0.25x[/tex]

The second rental company will charge [tex]=40+0.10x[/tex]

Now, we want the rental charges of second company to be less expensive then the first.

So we get the inequality,

[tex]30+0.25x>40+0.10x[/tex]

[tex]0.25x-0.10x>40-30[/tex]

[tex]0.15x>10[/tex]

[tex]x>\frac{1000}{15}[/tex]

[tex]x>66.667[/tex] miles

Hence, at least 66.667 miles should be driven on a day.

What is the distance between points A and B?


___ units

Answers

we know that

the distance's formula between two points is equal to

[tex]d=\left|xB-xA\right|[/tex]

substitute

[tex]d=\left|1-(-5)\right|[/tex]

[tex]d=6\ units[/tex]

therefore

the answer is

[tex]6\ units[/tex]

The distance between two point [tex]A{\text{ and }}B[/tex] is [tex]\boxed{{\mathbf{6 units}}}[/tex].

Further explanation:  

The distance between two points is the modulus of difference of the given two points.

The distance between two points can be found by the distance formula as,

[tex]\left| {B - A} \right|[/tex]  

Here, [tex]A{\text{ and }}B[/tex] are the points on the number line.

The distance cannot be negative therefore modulus is applied in the formula.

Step by step explanation:

Step 1:

First we determine the points from the given number line.

It can be observed from the given number line that there are two points one is on the left side of the origin and the second is right side of the origin.

The point [tex]A[/tex] is [tex]- 5[/tex] and the point [tex]B[/tex] is 1.

Step 2:

Now use the distance formula to obtain the distance between the two points  [tex]A{\text{ and }}B[/tex].

Here, the value of A is [tex]-5[/tex] and B is 1.

Substitute the value of [tex]A{\text{ and }}B[/tex] to obtain the distance as,

[tex]\begin{aligned}d&= \left| {B - A} \right| \\&= \left| {1 - \left( { - 5} \right)} \right|\\&= 6{\text{ units}}\\\end{aligned}[/tex]  

Therefore, the distance between two point [tex]A{\text{ and }}B[/tex] is [tex]6{\text{ units}}[/tex].

if an angle is acute then its measure is 30 degrees true or false

Answers

False. An acute angle's measure is anywhere from 0 to 90 degrees. So it doesn't have to be 30 degrees, it can be anywhere in that range.
Final answer:

An acute angle is any angle less than 90 degrees, and while 30 degrees is an example of an acute angle, it is not accurate to say that all acute angles must be 30 degrees.

Explanation:

The statement 'If an angle is acute then its measure is 30 degrees' is false. An acute angle is defined as any angle that is less than 90 degrees. While 30 degrees is indeed an example of an acute angle, an acute angle can be any value less than 90 degrees. For example, 45 degrees, 20 degrees, or 1 degree are also acute angles. Therefore, it is not accurate to say that an acute angle must be 30 degrees.

Twenty-five members of the eighth grade class at Park Center Middle School are going to a museum and then to lunch. Each student must pay an entrance fee to the museum and $7.25 for lunch. The total cost for the trip is $443.75. What is the entrance fee for one student?

Answers

There are two costs involved:

1) the cost for lunch, which is given as a rate per student: $7.25/student

2) the cost for the trip which is $443.75 to be divided by the 25 students, so it is $443.75 / 25 = $17.75/student

Now, you can add up those two costs per student to have the total cost per student:

$7.25 + $17.75 = $25.00/student

Answer: $25.00

Answer: $17.75

Step-by-step explanation: $443.75 / 25 = $17.75

(x,y)     x2 = x and y2 = y
now we sub
(6 + x)/2 , (8 + y)/2 = 3/2

(6 + x) / 2 = 3
6 + x = 3 * 2
6 + x = 6
x = 6 - 6
x = 0

(8 + y) / 2 = 2
8 + y = 2 * 2
8 + y = 4
y = 4 - 8
y = -4

A bag contains 8 blue marbles, 5 green marbles and 7 red marbles. If Alicia removes two marbles without replacing them, what is the probability that he will choose red, then green?

Answers

Final answer:

To find the probability of choosing a red marble, then a green marble without replacement, multiply the probabilities of the individual events which is  7/76.

Explanation:

To find the probability that Alicia will choose red, then green marbles, we need to calculate the probability of drawing a red marble and then a green marble without replacement.

Given that there are 8 blue marbles, 5 green marbles, and 7 red marbles in the bag, the probability of drawing a red marble first is 7/20.

After removing the red marble, there are 19 marbles left in the bag, including 5 green marbles. Therefore, the probability of drawing a green marble second is 5/19.

To find the combined probability, we multiply the probabilities of the individual events:

P(Red, then Green) = P(Red) * P(Green | Red) = (7/20) * (5/19) = 35/380 = 7/76.
