Answer:
2.96cm
Step-by-step explanation:
C= 2x Pi x Radius
9.31 = 2 x Pi x Radius
9.31/2 = Pi x Radius
4.655 = Pi x Radius
4.655/3.14 = Radius
1.4824840764331210191082802547771 = Radius
Now, that you have worked out the radius which is half the diameter
Radius + Radius = Diameter
1.4824840764331210191082802547771 + 1.4824840764331210191082802547771 = 2.964968153
= 2.96cm to 2 d.p
You can double check because C= 2 x Pi x Radius
9.31 = 2 x 3.14 x 1.482
I'm stuck on a math question. "A submarine is descending to examine the seafloor 2100 feet below the surface. It takes the submarine 2 hours to make this descent. Write an equation to represent the relationship between the submarines elevation and time."
Answer:
-1,050
Step-by-step explanation: This is quite simple first we know that 2,100 is negative(-2,100) because it is descending/going down. So now we know that we can divide -2,100 by 2 which sums up to 1,050. But we are going to have to add a negative sign due to the fact that if the two integers you are dividing are opposite signs it would be negative. So if you add a negative sign to 1,050 it would be -1,050. Just to keep in mind that opposites make negative when dividing I will put the integer rules below.
Answer:
The answer is -1,050.
Step-by-step explanation:
An equation to represent the relationship between the submarines elevation & time would be y=-1,050x. Since we know that in two hours the submarine can reach 2,100 feet below the surface we need to figure out how long the submarine can reach in 1 hour. So we do 2,100/2 which equals 1,050. And since the submarine going below, it turns into -1,050.

Xavier is running a fundraiser for the Make-A-Wish Foundation. He is selling each cup of hot chocolate for $2.50 and each doughnut costs $3.75. He wants to sell at most 35 cups of hot chocolate. His end goal is more than $220. Write a system of linear inequalities to model the scenario and identify two possible solutions.
Answer:
h = # cups hot chocolate
d = # doughnuts
2.50h + 3.75d > 220
h ≤ 35
possible solution: 37 doughnuts, 34 cups hot chocolate
possible solution: 30 doughnuts, 50 cups hot chocolate

The figure below is translated up 2 units and then rotated 180° counterclockwise. What are the coordinates of the image of point Y after these transformations?
Answer:
-2
Step-by-step explanation: theres no image so i cant tell for sure but if it is rotating counterclockwise then that means its negative.
The coordinates of the image of point Y after these transformations is -2. The figure given has been translated up two units and turned 180 degrees counterclockwise.
How do we find the Cartesian coordinate plane?The Cartesian coordinate plane is an endless two-dimensional plane. On an endless 2d plane, any two-dimensional figure may be drawn. A location is assigned to each point in a Cartesian plane.
The figure given has been translated up two units and turned 180 degrees counterclockwise.
After these changes, the coordinates of the image of point Y are -2.
Hence, the coordinates of the image of point Y after t, These transformations is -2.

Answer:
[tex]x = - 3[/tex]
[tex]y = - 2[/tex]
Step-by-step explanation:
Since y=x+1 plug it into bottom equation as y.
[tex]x + 1= 5x + 13[/tex]
Subtract 1 from both sides
[tex]x = 5x + 12[/tex]
Subtract 5x from both sides
[tex] - 4x = 12[/tex]
Divide both sides by -4
[tex]x = - 3[/tex]
Now x=-3 into the top equation to find y
[tex] - 3 + 1 = - 2[/tex]

What's true about a translation
Answer:
A translation moves every point of a figure or a space by the same amount in a given direction. The reflection of a red shape against an axis followed by a reflection of the resulting green shape against a second axis parallel to the first one results in a total motion which is a translation of the red shape to the position of the blue shape.
Samantha correctly answered 36 out of 48 questions on a test. She must score 70% or greater to pass the test. Did she pass?
Answer:
Yes
Step-by-step explanation:
You see that you need a percentage. You are given the amount that she got wrong, assuming the questions are weighted the same, you divide 36 by 48. This gives you .75. Then you multiply .75 by 100% giving you 75%.

In right triangle ABC, altitude CD with length h is drawn to its hypotenuse. We
also know AD = 12 and DB = 3.
Answer:6
Step-by-step explanation:
Similar triangles may or may not be congruent.
The value of h is 6.
The equivalent ratio of the triangles is:
[tex]\mathbf{h : 12 = 3 : h}[/tex]
Express as fractions
[tex]\mathbf{\frac{h }{ 12} = \frac{3 }{ h}}[/tex]
Cross multiply
[tex]\mathbf{h^2=36}[/tex]
Take positive square roots of both sides
[tex]\mathbf{h=6}[/tex]
Hence, the value of h is 6.

What is your hypothesis from the activity in the lesson? Will the shorter cylinder or taller cylinder have the larger volume? Or, will both cylinders have the same volume? Explain your reasoning using complete sentences. [Note: There is no wrong answer as long as you make a hypothesis and explain your reasoning using complete sentences.]
Answer:
Taller because it is bigger and more likely to have greater volume
Step-by-step explanation:
its correct 100%
The correct statement is,
''The taller cylinder have the larger volume than shorter cylinder.''
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Will the shorter cylinder or taller cylinder have the larger volume.
Since, We know that;
The volume of a cylinder is calculated by multiplying the area of the base by the height.
And, since the height of the taller cylinder is greater than the shorter cylinder, it is likely to have a larger volume.
Thus, The taller cylinder have the larger volume than shorter cylinder.

John has $5.05 in quarters and nickels in his pocket. If John only has 25 coins in his pocket, how many of the coins are quarters?
Answer:
Step-by-step explanation:
q+n=25
n=25-q
25q+5n=505, using n=25-q in this equation gives you
25q+5(25-q)=505
25q+125-5q=505
20q+125=505
20q=380
q=19
So 19 of the coins are quarters.
Answer:
John has 19 quarters out of 25 coins.

solve for x and y 5x + 3y=35, 2x+4y=28
Answer:
Step-by-step explanation:
Let's solve your system by substitution.
5x+3y=35;2x+4y=28
Step: Solve 5x+3y=35 for x:
5x+3y=35
5x+3y+−3y=35+−3y(Add -3y to both sides)
5x=−3y+35
5x/ 5 = −3y+35/ 5 (Divide both sides by 5)
Step: Substitute −3/ 5 y+7 for x in 2x+4y=28:
2x+4y=28
2( −3/ 5 y+7)+4y=28
14/ 5 y+14=28 (Simplify both sides of the equation)
14/ 5 y+14+−14=28+−14 (Add -14 to both sides)
14/ 5 y=14
14/ 5 y/ 14/ 5 = 14/ 14/ 5
(Divide both sides by 14/5)
y=5
Step: Substitute 5 for y in x= −3/ 5 y+7:
x= −3/ 5 y+7
x= −3/ 5 (5)+7
x=4 (Simplify both sides of the equation)
Answer:
x=4 and y=5
Point F is on line CD. Find the measure of angle CFE.
Answer:
∠ CFE = 28°
Step-by-step explanation:
∠ CFE and ∠ DFE are adjacent angles and are supplementary, sum to 180°
∠ CFE + 152° = 180° ( subtract 152° from both sides )
∠ CFE = 28°
Adjacent angles share the common side as well as a common vertex (corner point), and they do not overlap. If we decompose the term "adjacent angles".
Adjacent angles:It's simple, and we see what it means: two angles that are next to each other.Its common side and vertex will be shared by the adjacent angles. If the total of two angles equals 180°, they are said to be supplementary angles. A linear pair is created when two additional angles are next to one another. 180° is equal to the sum of two adjacent supplementary angles.We have, ∠ EFD = 152°
∠ CFE and ∠ DFE are adjacent angles and are supplementary, summing to 180°
[tex]\therefore[/tex]
∠CFE + ∠EFD = 180° (Linear pair)
∠CFE +152° = 180°
∠CFE= 180°-152°
∠CFE= 28°
