The mean distance that and Tina drove was 153 kilometers.If Ben drove 24 kilometers more than Tina,what was the distance that Tani drove?
Answers
Answer:
141 km
Step-by-step explanation:
Given data
Mean distance= 153km
Let Tina dirve=x km
Ben= x+ 24
Number of participants= 2
Hence,
Mean= total distance/number of participants
153= x+24+x/2
cross multiply
153*2= x+24+x
306 =2x+24
306-24= 2x
282=2x
Divide both sides by 2
x= 282/2
x= 141km
Hence Tina drove 141 km

A right rectangular prism has a base with an area of `25\ \frac{1}{2}`square feet and a volume of 153 cubic feet. What is the height, in feet, of the right rectangular prism?
Answers
Answer:
Height = 6 feet
Step-by-step explanation:
Given the following data;
Base area = 25½ ft²
Volume = 153 ft³
To find the height of the right rectangular prism;
Mathematically, the volume of a right rectangular prism is given by the formula;
Volume = base area * height
Substituting into the formula, we have;
153 = 25½ * height
153 = 51/2 * height
Cross-multiplying, we have;
306 = 51 * height
Height = 306/51
Height = 6 feet
Right rectangular prism is also called cuboid. The height of the right rectangular prism considered is evaluated as of 6 ft
How to find the volume of a right rectangular prism?Suppose that the right rectangular prism in consideration be having its dimensions as 'a' units, 'b' units, and 'c' units, then its volume is given as:
[tex]V = a\times b \times c \: \: unit^3[/tex]
For this case, we're provided that:
Base area of the right rectangular prism = [tex]25\dfrac{1}{2} = 25 + 0.5 = 25.5 \: \rm ft^2[/tex]Volume of the right rectangular prism = [tex]153\: \rm ft^3[/tex]Let the length and width of the prism be L ft and W ft
Let the heigth of the prism be H ft
Then, we get:
Area of base = [tex]L \times W = 25.5 \: \rm ft^2[/tex] (since base is a rectangle with length L and width W).Volume of prism = [tex]V = H \times L \times W = H \times 25.5 = 153 \: \rm ft^3[/tex]Thus, we get:
[tex]H \times 25.5= 153\\\\\text{Dividing both the sides by 25.5}\\\\H = \dfrac{153}{25.5} = 6 \: \rm ft[/tex]
Thus, the height of the right rectangular prism considered is evaluated as of 6 ft.

Jackie you should know that the supplemental angles always add to 180° :)
That's like angles 1 & 2 or 55° & 1 . both are supplemental and add to 180°
Knowing this should make answering this pretty easy. :)
180 = ∠1 + 55
125 = ∠1
∠3 =∠1
∠2 = 55°
since line g is parallel to f , we know all the angles in the same places of line f are identical... got it?

D. x =15, y = 5√3
Answers
9514 1404 393
Answer:
D. x = 15; y = 5√3
Step-by-step explanation:
You don't need to know any trig to select the correct answer. You only need to know that the lengths of both sides must be less than the length of the hypotenuse. It is also helpful to know that √3 is about 1.732, so 10√3 ≈ 17.32.
Since x < 10√3, only answer choices A and D are viable.
Since y < 10√3, only answer choice D is viable.
_____
If you want to solve this using trig relations, you can recall that the sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. This means short side y is half the length of the hypotenuse 10√3, so y = 5√3. It also means longer side x is √3 times y, so is x = (5√3)√3 = 5·3 = 15.
x = 15; y = 5√3

Answers
Answer:
21.07 m²
Step-by-step explanation:
Please find the complete question in the attached image
Area of shaded region = area of rectangle - area of semicircle
Area of semicircle = [tex]\frac{1}{2}[/tex]πr²
π = 3.14
r = radius = 14/2 = 7m
the diameter of the semicircle is 14m , thus the radius would be half of the diameter
(1/2) x 3.14 x 7² = 76.93 m^
Area of a rectangle = length x width
width = radius of semicircle = 7
14 x 7 = 98 m²
Area of shaded region = 98 m² - 76.93 m^ = 21.07 m²

Answer:
0.50
Step-by-step explanation:
The question states at least 2 which means 2 or more.
The only applicable numbers to look at would be 2 and 3.
First of all we find 2 since it's missing.
Now all probability distributions must add up to 1.
As we can see there are 0.20, 0.30 and 0.40 which is equal to 0.90. Therefore 1 - 0.90 = 0.10 which would be 2.
Hence, the peobability that x is at least 2 is 0.10 + 0.40 = 0.50.
What is the probability of rolling 2 number cubes and getting a 5
on the first one and an even number on the second number cube?
Answers
Step-by-step explanation:
n(s) for 2 cubes =6×6=36
n (5, even) = 3
(5,2) (5,4) & (5,6)
so, probability = 3/36 = 1/12
3x2=6
So 6/12 are even but the answer to your question would be 2/12 because there’s only one 5 in each cube which makes there two fives in total.
Answer: 2/12
One cube: 1/6
Both cubes 2/12

write additive and multiplicative inverse of19/-6 and-2/3
Answers
Additive inverse of 19/-6 is 19/6
Additive inverse of -2/3 is 2/3
Multiplicative inverse of 19/-6 is -6/19
Multiplicative inverse of -2/3 is 3/-2 (also written as -3/2)
Step-by-step explanation:
(a) The additive inverse of a number is that number that when added to it gives 0.
For example, the additive inverse of x is -x.
This is because adding -x to x gives 0. i.e
x + (-x) = 0
In other words, the additive inverse of a number is the negative of that number.
Given:
(i) 19/-6
The additive inverse of 19/-6 is the negative of 19/-6 which is -(19/-6).
-(19/-6) then gives 19/6
Therefore, the additive inverse of 19/-6 is 19/6
(ii) -2/3
The additive inverse of -2/3 is the negative of -2/3 which is -(-2/3).
-(-2/3) then gives 2/3
Therefore, the additive inverse of -2/3 is 2/3
(b) The multiplicative inverse of a number is that number that when multiplied by it gives 1.
For example, the multiplicative inverse of y is 1/y.
This is because multiplying y by 1/y gives 1. i.e
y x (1/y) = 1
In other words, the multiplicative inverse of a number is the reciprocal of that number.
Given:
(i) 19/-6
The multiplicative inverse of 19/-6 is the reciprocal of 19/-6 which is 1/(19/-6).
1 / (19/-6) then gives -6/19
This is found by just swapping the numerator(19) and the denominator(-6)
Therefore, the multiplicative inverse of 19/-6 is -6/19
(ii) -2/3
The multiplicative inverse of -2/3 is the reciprocal of -2/3 which is 1/(-2/3).
1 / ( -2/3) then gives 3/-2
This is found by just swapping the numerator(-2) and the denominator(3)
Therefore, the multiplicative inverse of -2/3 is 3/-2 (also written as -3/2).
Tyler and Bethany have 240 feet of fencing with which to build a garden. Tyler wants the garden to be in the shape of a square, while Bethany wants it to be rectangular with a length of 50 feet and a width of 70 feet. Which design would give the maximum area for the garden? Explain.
Bethany’s design would give the larger garden because the area would be 3,500 ft2.
Tyler’s design would give the larger garden because the area would be 3,600 ft2.
Bethany’s and Tyler’s designs would give a garden with the same area.
Bethany’s and Tyler’s designs are not possible with the given amount of fencing.
Answers
Answer:
Step-by-step explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.
A is wrong. A square maximizes the area.
B is correct.
C The areas are not the same. C is wrong.
D is wrong. Both fence proposals work.
Answer:
B is correct
Explanation:
Tyler's square is going to be 60 feet on each side. That is 3600 square feet.
Bethany can build a rectangle to her shape. It will be 240 feet of fencing. But it will give only 3500 square feet.
