The cheetah ran 960 meters in 30 seconds with an average speed of
36 m/s.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
We know, distance = speed×time or d = st.
Given, A cheetah runs with an average speed of 32 m/s for 30 seconds.
Here, s = 32 m/s and t = 30 seconds.
Therefore, d = 32×30 meters.
d = 960 meters.

Solve the equation for n
3(n-5) = -21
Answer:
n=−2
Step-by-step explanation:
Let's solve your equation step-by-step.
3(n−5)=−21
Step 1: Simplify both sides of the equation.
3(n−5)=−21
(3)(n)+(3)(−5)=−21(Distribute)
3n+−15=−21
3n−15=−21
Step 2: Add 15 to both sides.
3n−15+15=−21+15
3n=−6
Step 3: Divide both sides by 3.
Answer: n= -2
Step-by-step explanation:
3(n−5)=−21
Divide both sides by 3.
n−5=
3
−21
Divide −21 by 3 to get −7.
n−5=−7
Add 5 to both sides.
n=−7+5
Add −7 and 5 to get −2.

The length of a rectangle is 3 times the width the perimeter is 24ft find the dimensions of the rectangle
Step-by-step explanation:
let the unknown be x
length = 3x
width = x
Perimeter = 2 lengths + 2 widths
24 ft = 3x + 3x + x + x
24 ft = 8x
3 ft = x
dimensions = length × width
= 3(3) × 3
= 9 ft × 3 ft
if you wanna check,
24 ft = 3(3) + 3(3) + 3 + 3
24 ft = 24

Solve 24>−3r≥−9. please
Answer:
−8<r≤3
Step-by-step explanation:
The final inequality of 24>−3r≥−9 is -8 < r ≤ 3.
Given,
24>−3r≥−9
We need to solve this inequality.
What are inequalities?We have,
< = less than
> = greater than
≤ = less than and equal
≥ - greater than and equal
If we change the sign we change the inequality.
Example:
2 > -1
Multiply -1 on both sides.
-2 < 1
We have,
24 > -3r ≥ -9
We can cancel the common factor.
3 x 8 > -3r ≥ - 3 x 3
8 > -r ≥ -3
Multiply - on all sides.
-8 < -(-r) ≤ -(-3)
-8 < r ≤ 3
This means r values are between -8 and 3.
r = ( -8, 3]
Thus the final inequality of 24>−3r≥−9 is -8 < r ≤ 3.

Given:
Two triangles are congruent, i.e., [tex]\Delta ABC\cong \Delta XYZ[/tex].
To find:
All the measures of both triangle.
Solution:
We have,
[tex]\Delta ABC\cong \Delta XYZ[/tex].
We know that, corresponding parts of congruent triangles are congruent (CPCTC).
[tex]\angle A=\angle X[/tex]
[tex]\angle B=\angle Y=90^\circ[/tex]
[tex]\angle C=\angle Z=37^\circ[/tex]
It triangle ABC,
[tex]\angle A+\angle B+\angle C=180^\circ[/tex] (Angle sum property)
[tex]\angle A+90^\circ+37^\circ=180^\circ[/tex]
[tex]\angle A+127^\circ=180^\circ[/tex]
[tex]\angle A=180^\circ -127^\circ[/tex]
[tex]\angle A=53^\circ[/tex]
So,
[tex]\angle A=\angle C=53^\circ[/tex]
[tex]AB=XY=3\text{ units}[/tex]
[tex]BC=YZ=4\text{ units}[/tex]
[tex]AC=XZ=5\text{ units}[/tex]
Therefore, m∠A = 53˚, m∠B =90˚ , m∠C =37˚ , m∠X = 53˚, m∠Y =90˚ , m∠Z =37˚ , Segment AB = 3 units , Segment BC = 4 units , Segment AC = 5 units , Segment XY = 3 units , Segment YZ = 4 units , Segment XZ = 5 units .

reduce [tex]\frac{54}{81}[/tex]
Answer:
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]
Step-by-step explanation:
Fraction Reduction
To reduce a fraction, we try to divide both the numerator and denominator by the very same number until no more numbers can be found.
The fraction to reduce is:
[tex]\displaystyle \frac{54}{81}[/tex]
Since the denominator is odd, we cannot divide by 2, but we can divide by 3:
[tex]\displaystyle \frac{54}{81}=\frac{18}{27}[/tex]
We divide by 3 again:
[tex]\displaystyle \frac{18}{27}=\frac{6}{9}[/tex]
We divide by 3 one last time:
[tex]\displaystyle \frac{6}{9}=\frac{2}{3}[/tex]
[tex]\text{The reduced fraction is } \frac{2}{3}[/tex]

In the diagram below, all measurements are given correct to the nearest cm. Calculate the greatest possible area of the shaded region.
The possible area of the region that is shaded is given as 462cm.
How to solve for the area of the shaded regionThe picture here shows us two rectangles.
The area of a rectangle is given as L * w
= length x width
We have to find the area of the first rectangle
21cm x 42cm
= 882 cm
Next we find the area of the rectangle inside
15cm x 28cm
= 420
To get the area of the shaded region
= 882 - 420
= 462cm

(1) 5 years ago a man's age was 5 times the age of his daughter's. 3 years hence, twice
his
age will be equal to 6 times his daughter's age. Find their present ages.
Answer: Daughter = 13, Man = 45
Step-by-step explanation:
Today 5 yrs ago 3 years hence (future)
Man x x - 5 x + 3
Daughter y y - 5 y + 3
5 years ago a man's age was 5 times the age of his daughter's
EQ1: x - 5 = 5(y - 5) → x - 5 = 5y - 25 → x - 5y = -20
3 years hence, twice the man's age will be equal to 6 times his daughter's age.
EQ2: 2(x + 3) = 6(y + 3) → 2x + 6 = 6y + 18 → 2x - 6y = 12
Solve the system of equations using the Elimination method:
EQ1: x - 5y = -20 → -2(x - 5y = -20) → -2x + 10y = 40
EQ2: 2x - 6y = 12 → 1(2x - 6y = 12) → 2x - 6y = 12
4y = 52
÷4 ÷4
y = 13
Substitute y = 13 into either equation to solve for x:
EQ1: x - 5y = -20
x = 5y - 20
x = 5(13) - 20
x = 65 - 20
x = 45
