Answer:
If you can maintain this speed you will travel 120 km in 1 hour.
Explanation:
The translated question is, A cheetah can travel 20 kilometers in 10 minutes. If I could maintain this speed for one hour, how many kilometers would you travel?.
Let us find the speed of cheetah
Distance traveled = 20 km
Time taken = 10 minutes = 10/60 = 1/6 hours
So speed = [tex]\frac{20}{\frac{1}{6} } =120[/tex]km/hr.
So speed of cheetah = 120 km/hr, which means cheetah will travel 120 km in 1 hour.
If you can maintain this speed you will also travel 120 km in 1 hour.

A company did a quality check on all the packs of nuts it manufactured. Each pack of nuts is targeted to weigh 18.25 oz. A pack must weigh within 0.36 oz of the target weight to be accepted. Find the absolute value inequality that describes the situation and solve it to find the range of rejected masses, x. |x − 18.25| > 0.36; x < 17.89 or x > 18.61 |x − 0.36| + 18.25 > 0; x < 17.89 or x > 18.61 |x − 18.25| > 0.36; x < 18.25 or x > 18.61 |x − 0.36| + 18.25 > 0; x < 18.25 or x > 18.61
Answer: the first choice, |x − 18.25| > 0.36; x < 17.89 or x > 18.61
Explanation:
1. Target weight: 18.25 oz
2. Variability accepted: 0.36 oz
3. Range of accepted masses: 18.25 oz - 0.36 oz ≤ x ≤ 18.25 oz + 0.36 oz
4. Addition property of the inequalities (subtract 18.25 oz to the three parts of the inequality):
- 0.36 oz ≤ x - 18.25 oz ≤ 0.36 oz
5. Definition of absolute value inequality: | x - a | ≤ c equals - c ≤ x - a ≤ c
∴ - 0.36 ≤ x - 18.25 ≤ 0.36 equals | x - 18.25 | ≤ 0.36, which is the range of accepted masses.
6. The range of rejected masses is the complement, so it is:
|x - 18.25 | > 0.36
7. Solve the inequality to find the range of rejected masses:
a) x - 18.25 > 0.36 ⇒ x > 18.25 + 0.36 ⇒ x > 18.61
b) x - 18.25 < 0.36 ⇒ x < 18.25 - 0.36 ⇒ x < 17.89
Leila is paid $290 per week by Famous Footwear, plus 3% on all sales over $500. During one week, her total sales were $960. Find her gross earnings.
$303.80
$13.80
$968.70
$318.80
Leila's gross earnings are calculated by adding her base pay of $290 to her commission of $13.80, which is 3% of her sales over $500. For the week, her total gross earnings are $303.80.
The question involves calculating Leila's gross earnings for a week where she sold $960 worth of merchandise while working at Famous Footwear. To find her earnings, we need to calculate her base pay plus the commission on sales over $500.
Leila's base pay is $290 per week. Since she sold $960, the amount over $500 that is eligible for commission is $960 - $500 = $460. Her commission is 3% of this amount, which is 0.03 * $460 = $13.80.
Therefore, Leila's total gross earnings for the week are her base pay plus her commission: $290 + $13.80 = $303.80.
The product of two consecutive square number is 144
Answer: Two consecutive square numbers be 16 and 9.
Step-by-step explanation:
Let first consecutive square number be x²
Let second consecutive square number be (x+1)²
According to question,
[tex]x^2\times (x+1)^2=144[/tex]
Now we'll do this by factorisation,
[tex]144=2\times2\times2\times2\times3\times3\\\\144=16\times 9[/tex]
So, two consecutive square numbers are 16 and 9
Consecutive numbers are numbers that follow one another.
The consecutive squares are: 9 and 16
Let the bigger square be x^2
So, we have:
[tex]\mathbf{(x - 1)^2 \times x^2 = 144}[/tex]
Express 144 as 12^2
[tex]\mathbf{(x - 1)^2 \times x^2 = 12^2}[/tex]
Take square roots of both sides
[tex]\mathbf{(x - 1)\times x = 12}[/tex]
Expand
[tex]\mathbf{x^2 - x = 12}[/tex]
Rewrite as:
[tex]\mathbf{x^2 - x - 12 = 0}[/tex]
Expand
[tex]\mathbf{x^2 - 4x +3x- 12 = 0}[/tex]
Factorize
[tex]\mathbf{x(x - 4) +3(x- 4) = 0}[/tex]
Factor out x - 4
[tex]\mathbf{(x +3) (x- 4) = 0}[/tex]
Solve for x
x= -3 or x = 4
x cannot be negative.
So: x = 4
Square both sides
[tex]\mathbf{x^2 = 4^2}[/tex]
[tex]\mathbf{x^2 = 16}[/tex]
Calculate the smaller square
[tex]\mathbf{(x - 1)^2 = (4-1)^2}[/tex]
[tex]\mathbf{(x - 1)^2 = 9}[/tex]
Hence, the consecutive squares are: 9 and 16

True or false : if an individual or business breaks a contract, it automatically goes to court.
Answer:
It's false, only if the situation gets worse.
Step-by-step explanation:
On the off chance that a debate over a contract emerges and casual endeavors at determination fall flat, the foremost common next step may be a claim. On the off chance that the sum at issue is underneath a certain dollar figure (ordinarily $3,000 to $7,500 depending on the state), the parties may be able to resolve the issue in small claims court.

Jake recorded a special album in honor of mother’s day his mom was so excited she purchased 40% of the copies in the store she has 80 copies of the cd how many cds did the stores have for sale
Answer:
200 CD's.
Step-by-step explanation:
Jake recorded a special album in honor of mother's day. His mom was so excited that she purchased 40% of the copies in the store.
we have tell the total number of CD's in the store.
Let total number of CD's available in the store was = A
Then 40% of the total numbers of CD's = A×40% = 0.04 A
Since 0.04A = 80
A = 80/0.04 = 200
Therefore there were 200 CD's in the store for the sale.

A golfball is hit from ground level with an initial vertical velocity of 64 ft/s. After how many seconds will the ball hit the ground?
a. 3 seconds
b. 4 seconds
c. 5 seconds
d. 6 seconds
The ball hits the ground at unknown time (t) when the height (h) = 0
h(t) = -16t² + vt + h ⇒ v = 64, h = 0, h(t) = 0, find t
0 = -16t² + 64t
0 = -16t(t - 4)
0 = -16t or 0 = t - 4
t = 0 or t = 4
It starts at t = 0 seconds and ends at t = 4 seconds
Answer: B
Final answer:
Using the kinematic equation for vertical motion, we find that the golf ball will hit the ground after 4 seconds. We factor the kinematic equation to solve for the time given initial velocity and gravity's acceleration, ignoring the 0 time solution. TΔherefore, the correct option is b.
Explanation:
The question asks after how many seconds a golf ball hit from ground level with an initial vertical velocity of 64 ft/s will hit the ground. This problem involves kinematic equations of motion under the influence of gravity. We can use the equation for vertical motion: distance = initial velocity × time + 0.5 × acceleration × time². Since the ball returns to ground level, the distance covered is 0. Taking downward as positive, gravity's acceleration is +32 ft/s² (the usual acceleration due to gravity in units of ft/s²). We can rearrange the equation to solve for time (t): 0 = 64t + 0.5 × 32t². Factoring out t gives us t(64 + 16t) = 0, and solving for t gives us t = 0 or t = -64/16 = -4 seconds. Since time cannot be negative in this context, the positive solution reflects the time after launch, thus the answer is 4 seconds, which is option b.

Determine the equation of the ellipse.
Answer:
A) x²/25 + y²/9 = 1
Step-by-step explanation:
The major axis length is the sum of distances to the foci from the ellipse, 10. So the semi-major axis has length 10/2 = 5. The foci are on the x-axis, so the ellipse is oriented horizontally.
The semi-minor axis is the other leg of the right triangle having the focus and center as one leg, and the semi-major axis as the hypotenuse. This is obviously a 3-4-5 triangle, so the semi-minor axis length is 3.
When the ellipse is horizontal, the formula for it is ...
... (x/(semi-major axis))² + (y/(semi-minor axis))² = 1
... (x/5)² + (y/3)² = 1
... x²/25 + y²/9 = 1

7 people have averaged fewer than 4,000 steps.
Option A is the correct answer.
Given,
The bar graph of the number of steps on the horizontal line and the number of people on the vertical line.
We need to find how many people averaged fewer than 4,000 steps each day.
Read the bar graph.
Steps - 0 - 1,999
= 2 people
Steps - 2,000 - 3,999
= 5 people
Steps - 4,000 - 5,999
= 12 people
Steps - 6,000 - 7,999
= 7 people
Steps - 8,000 - 9,999
= 3 people
Find the number of people who have fewer than 4,000 steps.
We have,
Steps - 0 - 1,999
= 2 people
Steps - 2,000 - 3,999
= 5 people
So,
2 + 5 = 7
= 7 people
Thus 7 people have averaged fewer than 4,000 steps.

3x+126-126=2x+151-126 => 3x= 2x + 25
3x=2x+25 Now we will add monom (-2x) to the both sides and get
