Answer:
96m/s
Step-by-step explanation:
Given the velocity, v, in ft/s of an object given by the formula v=v0−32t,
Given
V = 39ft/s
t = 2secs
Required.
Initial velocity v0
Substitute the given parameters into the formula
v=v0−32t,
32 = v0-32(2)
v0 = 32+64
v0 = 96m/s
Hence the initial velocity of the object is 96m/s
the volume of a cylinder whose base area is 300sq.cm and height is 15 cm is
1)450
2)4500
3)45000
Answer:
(2)
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = area of base × height
= 300 × 15
= 4500 cm³
In a bag of marbles, the ratio of green to red marbles is 6 to 5. If there are 95 red marbles, how many total marbles are in the bag?
Answer:
I think the answer is 209
Step-by-step explanation:
6(green): 5(red)
if we divide 95 by 5 we get 19.
Lets multiply 6 by 19 and we get 114.
114 plus 95 is 209.

1. Andy uses between 2 and 3 ounces of glue to install 85 yards of shelving
2. Andy uses between 10 and 15 ounces of glue to install 38 yards of shelving
3. Andy issues between 15 and 20 ounces of glue to install 92 yards of shelving
4. Andy uses more than 25 ounces of glue to install 50 yards of shelving
Answer:

Step-by-step explanation:
92x0.2=18.4
18.4 is between 15 and 20
4. X varies directly with the square of y, where x>0,
and y >0. If x= 3 when y = 5, then what is the value
ofy when x= 48?
Answer:
The value of y, when x = 48 is y = 12/5
Step-by-step explanation:
The given parameters are;
x is directly proportional to y
Where x > 0, y > 0
For x = 3. y = 5
Therefore, we have;
x ∝ a·y²
For ,x = 3, when y = 5, we have;
3 = a × 5² = 25·a
∴ a = 25/3
When x = 48, we have;
48 = 25/3×y²
y² = 3/25 × 48 = 144/25
y = √(144/25) = 12/5
y = 12/5
The value of y, when x = 48 is y = 12/5.
A number cube is tossed 50 times, and a 2 is rolled 14 times. Find the experimental probability of not rolling a 2. Enter your answer as a simplified fraction.
Answer:
18/25
Step-by-step explanation:
With regards to the above information, we can infer that since a 2 is rolled 14 times, then 36[50 - 14]rolls are not 2.
The experimental probability would then be;
= 36/50
= 18/25
The experimental probability of not rolling a 2 is 18/25.

A triangle has sides with lengths of 26 meters, 39 meters, and 43 meters. Is it a right triangle?
Answer: No
Step-by-step explanation:
This triangle is not a right triangle because:
A right triangle must have one side that is exactly 90°.
A triangle with sides 26, 39, and 43 do not have any sides that total 90.
The answer to your question is no.
Best of Luck!
Answer:
No, the side don't equal 90

(a) Write down an expression for the perimeter of the rectangle, giving your
answer in its simplest form.
The perimeter of the rectangle is 62 cm.
(b) Work out the length of the rectangle.
The expression for the perimeter is 4x + 10 = 62 and the length of the rectangle is 18 cm.
What is a perimeter?The perimeter is the distance around the edge of a shape.
Given that the width of the rectangle is x cm, length is x+5, and the perimeter is 62.
The general equation for the perimeter of a rectangle is given by
2 (length + width) = perimeter
By substituting the values we get
2(x+5+x) = 62
i.e 4x+10 = 62
x=52/4 = 13
Then length is given by
x+5 = length
i.e length = 18
Hence the 4x + 10 = 62 is the expression for the perimeter of a rectangle of length 18cm.

Find the area of a circle that has a circumference of 175.84 inches
with explanation.
Will give brainliest.
Answer:
[tex]{ \boxed{ \bold{ \text{Area \: of \: a \: circle} \: = \tt{2461.76 \: {inches}^{2}}}}} [/tex]
☯ Question :Find the area of a circle that has a circumference of 175.84 inches.☯ Step - by - step explanation :☄ Given :
Circumference of a circle = 175.84 inches☄ To find :
Area of a circle = ?☄ First, we have to find :
Radius of a circle ( r )♨ Finding the radius of a circle :
[tex] \boxed{ \sf{Circumference \: of \: a \: circle = 2\pi \: r}}[/tex]
Substitute the value of circumference of a circle
[tex] \longrightarrow{ \sf{175.84 = 2\pi \: r}}[/tex]
Swap the sides of the equation
⟶ [tex] \sf{2\pi \: r \: = 175.84}[/tex]
Use [tex] \sf{ \pi \: ≈ \: 3.14}[/tex] , we obtain
[tex] \longrightarrow{ \sf{2 \times 3.14 \times r = 175.84}}[/tex]
Multiply : 2 by 3.14
[tex] \longrightarrow{ \sf{6.28 \: r = 175.84}}[/tex]
Divide both sides by 6.28
[tex] \longrightarrow{ \sf{ \frac{6.28 \: r}{6.28} = \frac{175.84}{6.28}}} [/tex]
[tex] \longrightarrow{ \sf{r \: = \: 28 \: inches}}[/tex]
☞ Now , we have :
Radius of a circle ( r ) = 28 inchesFinding the area of a circle having the radius of 28 inches :
[tex] \boxed{ \sf{Area \: of \: a \: circle = \pi \: {r}^{2} }}[/tex]
Substituting the radius , we get :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = \pi \: {(28)}^{2} }}[/tex]
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \: \pi}}[/tex]
Using [tex] \sf{\pi \: ≈ \: 3.14}[/tex] , we obtain :
[tex] \longrightarrow{ \sf{Area \: of \: a \: circle = 784 \times 3.14 }}[/tex]
[tex] \longrightarrow{ \boxed{ \sf{Area \: of \: a \: circle = 2461.76 \: {inches}^{2} }}}[/tex]
Therefore , area of a circle is 2461.76 inches²
And we're done !

Step-by-step explanation:
This is a vocabulary question. The angles named by the relationships A-E are angles that have the transversal as a common side. "Interior" and "exterior" refers to the space between the crossing lines, or outside the crossing lines, respectively. "Alternate" means the angles are on opposite sides of the transversal; "consecutive" means they are on the same side of the transversal.
Angles are "corresponding" if they are in the same direction from the point of intersection where the transversal crosses the two lines. The angles will be "consecutive", but one will be interior and the other will be exterior.
4. angle 9 is left of q, above r; angle 16 is right of q and below s, so these are alternate exterior angles, C.
__
5. angle 3 is below r and left of p; angle 5 is above s and left of p, so these are consecutive interior angles, D.
__
6. angle 7 is below s and left of p; angle 15 is below s and left of q, so these are corresponding angles, A.
__
7. angle 1 is above r and left of p; angle 10 is above r and right of q, so these are consecutive exterior angles, E.
__
8. angle 2 is above r and right of p; angle 11 is below r and left of q, so these are alternate interior angles, B.
__
9. angles 6 and 13 are above transversal s.
the sum of the speeds of two trains is 721.6 miles per hour. if the speed of the first train is 8.4 mph faster than that of the second train find the speeds of each
Subtract the faster speed:
721.6 - 8.4 = 713.2
Divide by 2 trains:
713.2/2 = 356.6
The slower train is going 356.6 miles per hour.
The faster train is going 356.6 + 8.4 = 365 miles per hour.

Right triangle LMN is shown. What is the length of the hypotenuse, x, of triangle LMN? Round your answer to three decimal Places. Use the equation below.
Answer:
55.866 ft
Step-by-step explanation:
[tex] c^2 = a^2 + b^2 [/tex]
[tex] x^2 = 40^2 + 39^2 [/tex]
[tex] x^2 = 1600 + 1521 [/tex]
[tex] x^2 = 3121 [/tex]
[tex] x = \sqrt(3121} [/tex]
[tex] x = 55.8659 [/tex\
Answer: 55.866 ft
The length of the hypotenuse, x, of triangle LMN to 3 decimal place is
55.866 ft
using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the 2 other legs.
Therefore,
40²+ 39² = x²
1600 + 1521 = x²
x² = 3121
square root both sides
x = √3121
x = 55.8659108939
x ≈ 55.866 ft
