Which geometric construction depicts a ray?
Answer:
C is the answer
Step-by-step explanation:
i randomly found out
The geometric construction in option (C) depicts a ray.
What is ray?In mathematics, a ray is a segment of a line with a fixed starting point but no ending. It can go on forever in a single direction. A ray cannot be measured since it has no end point.
In the given geometric construction,
Diagram A, shows a parallelogram. Therefore, is not a ray.
In diagram B there is no starting point, it shows a line. Therefore, it is also not a ray.
In diagram C, there is a starting point and no ending point.

Two no's are in the ratio 5:3 if they differ by 18, what are the numbers
Let us consider the ration of two numbers be x
The two numbers are 5x and 3x
Since two numbers differ by 18, we can write the equation
5x – 3x = 18
2x = 18
x= 9
Therefore the two numbers are
5x = 5 x 9 = 45
and
3x = 3 x 9 = 27
∴ The two numbers are 45 and 27.

Answer:
4 1/2
Step-by-step explanation:
2 1/3 pounds and 2 1/6 pounds
convert the 1/3 pounds into x/6 by multiplying both numerator and denominator by 2 which equals 2/6
Then add 2+2 which gives 4 and the 1/6 and 2/6 which is equal to 3/6 which simplifies into 1/2.

you flip a coin,
What is P(heads)
write your answer as a percentage
The percent chance of it landing on heads is 50% and it landing on tails is 50%
So chances of it landing on heads is 50%
Answer:
50%
Step-by-step explanation:
since it is a 2 sided coin , and you flip it once, each side has a 50% chance of being landed on. there isn’t any more chance on one side than the other, so it would be 50% probability

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?
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.

Find the surface area and volume of the prisim it has 5cm 12cm 13cm and 28cm The surface area of the prism is (blank)cm2 The volume of the prism is (blank)cm3 pls help i need this quick!
Answer:
A = 1124 cm²
V = 840 cm³
Step-by-step explanation:
Assuming the prism is a triangular prism,
Applying,
V = 1/2bhL.................. Equation 1
Where V = volume of the prism, L= lenght of the prism, b = base of the triangle, h = height of the triangle
From the question,
Given: L = 28 cm, 12 cm, h = 5 cm
Substitute these values into equation 1
V = (5×12×28)/2
V = 840 cm³
Surface area (A) = bh+(a+b+c)L
A = (5×12)+(13+13+12)28
A = 60+1064
A = 1124 cm²
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.
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.

Find the measure of the are or angle indicated. Assume that lines which appear tanget are tangents
Given:
On a circle, UT and UV are two tangent
Measure of arc VT = 125 degrees.
To find:
The measure of angle TUV.
Solution:
Intersecting tangents theorem: According to this theorem, if two tangent are drawn to the circle then the measure of angle on the intersection is half of the difference of intercepted major arc and minor arc.
We know that the measure of complete arc of a circle is 360 degrees. So,
[tex]\text{Major arc}(VT)=360^\circ -\text{Minor arc}(VT)[/tex]
[tex]\text{Major arc}(VT)=360^\circ -125^\circ[/tex]
[tex]\text{Major arc}(VT)=235^\circ[/tex]
Using Intersecting tangents theorem, we get
[tex]m\angle TUV =\dfrac{1}{2}(\text{Major arc}(VT)-\text{Minor arc}(VT))[/tex]
[tex]m\angle TUV =\dfrac{1}{2}(235^\circ -125^\circ )[/tex]
[tex]m\angle TUV =\dfrac{1}{2}(110^\circ )[/tex]
[tex]m\angle TUV =55^\circ[/tex]
Therefore, the measure of angle TUV is 55 degrees.

1. You have $1000 to invest in two different accounts. To save the money you need for college, you need to average 5.7 percent interest. If the two accounts pay 4 percent and 6 percent interest, how much should you invest in each account? Options: A. $700 in 4%, $300 in 6% B. $550 in 4%, $450 in 6% C. $300 in 4%, $700 in 6% D. $150 in 4%, $850 in 6%
Answer:
D. $150 in 4%, $850 in 6%
Step-by-step explanation:
1. The amount available to invest in the accounts, A = $1,000
The amount of average interest rate needed = 5.7 percent = 0.057
The interest paid by one of the accounts, account 1, I₁ = 4 percent = 0.04
The interest paid by the other account, account 2, I₂ = 6 percent = 0.06
Let 'x' represent the amount invested in account 1 that pays 4% and let 'y' represent the amount invested in account 2, that pays 6% we get;
x + y = 1,000...(1)
0.04·x + 0.06·y = 0.057 × 1,000 = 57
∴ 0.04·x + 0.06·y = 57...(2)
Making 'y' the subject of equation (1) and (2), we have;
For equation (1), y = 1,000 - x...(3)
For equation (2), y = 950 - (2/3)·x...(4)
Subtract equation (4) from equation (3) gives;
y - y = 1,000 - x - (950 - (2/3)·x)
0 = 1,000 - 950 - x + (2/3)·x
0 = 50 - (1/3)·x
(1/3)·x = 50
x = 3 × 50 = 150
x = 150
The amount invested in the 4% account, x = $150
From equation (3), we have;
y = 1,000 - x
∴ y = 1,000 - 150 = 850
y = 850
The amount invested in the 6% account, y = $850.
Therefore;
$150 should be invested in the account that pays 4% while $850 should be invested in the account that pays 6%.
Answer:
$150 in 4%, $850 in 6%

Theodore needs to mix a 30% alcohol solution with a 50% alcohol solution to create 100 milliliters of a 32% solution. How many milliliters of each solution must Theodore use
Answer:
50 % alcohol solution = 10 millimetres
30 % alcohol solution = 90 millimetres
Step-by-step explanation:
two equations can be derived from this question
x + y = 100 equation 1
0.3x + 0.5y = 100 x 0.32 = 32
0.3x + 0.5y = 32 equation 2
where :
x = 30% alcohol solution
y = 50% alcohol solution
multiply equation 1 by 0.3
0.3x + 0.3y = 30 equation 3
subtract equation 3 from 2
0.2y = 2
y = 10
substitute for y in equation 1
x + 10 = 100
x = 100 - 10
x = 90
