PLEASE HELP ME Superman can fly on a speed of 20 miles per second Lois Lane is currently 5,000 miles away needs to be saved in exactly 5 minutes will Superman be able to get there in time
Answer:
He will get there in time
Step-by-step explanation:
Superman speed = 20miles per second and there are 60 seconds per minute, so Superman's speed is 1,200 miles per minute
1,200miles/minute * 5 minutes = 6,000 miles
6,000 miles > 5,000 miles so our boi will make it within 5 minutes

Answer:
£59.25
Step-by-step explanation:
It appears you can measure the height of the trapezoid [trapezium :-) ??]. If you can't, you can use the Pythagorean Theorem (image attached). Draw a line from the upper right-hand corner down to the baseline--the 20m side. You'll form a right triangle with one leg h , hypotenuse 17m and the other leg 8m (the difference between 20m and 12m).
(leg)^2 + (leg)^2 = (hypotenuse)^2
h^2 + 8^2 = 17^2
h^2 + 64 = 289
h^2 = 225
h = 15m
The area of the trapezium is [tex]A=\frac{1}{2}h\left(b_1+b_2\right)[/tex] where the b's are the lengths of the two bases (upper and lower sides).
[tex]A=\frac{1}{2}(15)(12+20)=\frac{1}{2}(480) = 240[/tex] m^2

You find a crystal in the shape of a prism. Find the volume of the crystal.
The point Bis directly underneath point E, and the following lengths are known:
• From A to B: 2 mm

What is the area of the base? ( 1 point) Explain or show your reasoning. (2 points)
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².
VolumeVolume is the amount of space occupied by a three dimensional shape or object.
Area of triangle = (1/2) * DF * height
Height = 10 - 6 = 4 mm, DF = AC = AB + BC = 2 + 3 = 5 mm
Area of triangle = (1/2) * 5 * 4 = 10 mm²
Volume of triangle prism = Area of triangle * AG = 10 * 4 = 40 mm³
Volume of rectangular prism = A to F * AC * AG = 6 * 5 * 4 = 120 mm³
Volume of crystals = 120 + 40 = 160 mm³
Area of base = AC * AG = 5 * 4 = 20 mm²
The Volume of crystals is 160 mm³ while the area of the base is 20 mm².

find the value of x please help
Answer:
x=37
Step-by-step explanation:
Area of triangle = x+x+x=180
= 78+65+x=180
=143+x=180
=x=180-143 (bring 143 to the otherside)
x=37
In the given figure, We are to find the respective value of x .
Solution :
We know that,
Sum of all the angles of the triangle = 180°
So,
[tex] \qquad \sf \dashrightarrow{ x {}^{ \circ} + 65 ^{ \circ} +78 ^{ \circ} = 180}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} + 143^{ \circ} = 180^{ \circ}}[/tex]
[tex] \qquad \sf \dashrightarrow{ x ^{ \circ} = 180^{ \circ}} - 143^{ \circ}[/tex]
[tex] \qquad \bf \dashrightarrow{ x ^{ \circ} = 37^{ \circ}}[/tex]
Therefore, The value of x is 37°

d° = f°
a° + d° = 180°

Given:
Two pairs of parallel lines j and k, and r and s traverse each other.
d° = f° {opposite angles}
a° + d° = 180°
This is an incorrect statement.

What is the percent of change from 8 to 4?
Answer:
50% decease
Step-by-step explanation:
A change from 8 to 4 represents a negative change (decrease) of -50%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent = New - Old/Old x 100
Percent = 4-8/8 x 100
Where: 8 is the old value and 4 is the new value. In this case we have a negative change (decrease) of -50 percent because the new value is smaller than the old value.
Hence, 50% decrease
Check Answer:
8 x 50% = 4
8 - 4 = 4
Hence, 50% decrease is the correct answer.

Answer:
C is the formula you should use and the rest of the answers are below
Step-by-step explanation:
Hence, the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.
We have Variance.
We have to specify the formula of variance.
What is Variance?Variance is a measure of dispersion that takes into account the spread of all data points in a data set.
According to the question, the following formulae for variance are used according to the need.
For a Complete Population divide by the size n -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex]
For a Sample Population divide by the sample size minus 1
[tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex]
Hence, the the formulae to calculate the variance are -
[tex]\sigma^2 = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n}[/tex] for a complete population and [tex]s^{2} = \frac{\displaystyle\sum_{i=1}^{n}(x_i - \mu)^2} {n-1}[/tex] for a sample population.

Answer
Club = 7
Diamond = 6
Spade = 2
Heart = 5
Step-by-step explanation
Here it shows that 1 club + 1 diamond + 1 spade is equal to 15. Ok, let's get back to that one later.
In the next hint it shows that 3 clubs equals 21. So, in order to get the value of the club, divide 21 by 3, and you'll get 7. This means that 7 is the value of the club.
Now on to the third hint. Here it shows that 1 diamond plus 2 clubs are equal to 20. We already got the value of the club, which is 7, so add 7+7 and you'll get 14. Then, subtract 14 from 20 and you'll get the value of the diamond, which is 6.
Finally, the fourth hint. Here it shows that 1 diamond + 1 heart + 1 spade = 13. So, inorder to get the value of the heart, add the value of the diamond and the spade, which sums up to 8. Then subtract 8 from 13 and you'll get the value of the heart, which is 5.
