Round to the nearest whole number.
The volume of this solid figure is
Answer:
[tex]v = 183 {cm}^{3} to \: the \: nearest \: whole \: number[/tex]
Step-by-step explanation:
Volume of a cone is given as:
[tex]v = \frac{1}{3} \times\pi \times \ {r}^{2} \times h[/tex]
where,
pi = 3.14
r = radius = half of diameter; 10cm/2 = 5cm
h = height = 3cm + 4cm = 7cm
Thus,
[tex]v = \frac{1}{3} \times 3.14cm \times {5}^{2} cm \times 7cm[/tex]
[tex]v = \frac{1}{3} \times 3.14cm \times 25cm \times 7cm[/tex]
[tex]v = \frac{1}{3} \times 549.50 {cm}^{3} [/tex]
[tex]v = \frac{549.50 {cm}^{3} }{3} [/tex]
[tex]v = 183.17 {cm}^{3} [/tex]
[tex]v = 183 {cm}^{3} to \: nearest \: whole \: number[/tex]

Answer:
The answer is 116 degrees.
Step-by-step explanation:
The temperature at 4pm was 65 degrees Fahrenheit. The temperature dropped 5 degrees every hour from 4pm to 10pm. What is the temperature at 10pm? What are you doing dividing or multiplying? Can you write an equation to represent the problem and explain your process?
Answer: 35
Step-by-step explanation: It's an arith metic sequence that can be represented throigh the equation y= 65-5x where 5 is the amount of hous since 4pm and if you insert 6 for x you get 35
The mathematics problem involves subtraction, where the temperature drops 5 degrees per hour from 4pm to 10pm. The equation to represent this would be 65 - 5*6 = T. After performing the calculation, we find the temperature at 10pm is 35 degrees Fahrenheit.
Explanation:In this problem, you are dealing with a decline in temperature over time, which is considered as a subtraction problem. Since the temperature drops by 5 degrees every hour from 4pm to 10pm, that's a total of six hours (10pm - 4pm = 6 hours), so you'll subtract 5 degrees 6 times from the initial temperature of 65 degrees.
The equation to represent this problem is:
65 - 5*6 = T
This means you are subtracting 5 degrees six times from the initial temperature of 65 Fahrenheit to get the temperature (T) at 10pm. So, the calculation would be:
65 - (5*6) = 65 - 30 = 35
So, the temperature at 10pm is 35 degrees Fahrenheit.

Justine and Meagan played a trivia game. Justine answered a question incorrectly and lost 7 points. Then Meagan answered correctly and got the opposite score. Which is the correct way to represent that “the opposite of Justine’s score was equal to Meagan’s score”? a.–7 = 7
b.–(–7) = –7
C.–(7) = –7
D.–(–7) = 7
Answer:
-(-7)=7
Step-by-step explanation:
the opposite of the Justine score (-7) = Meghan score (7)
-(-7)=7
Final answer:
The correct representation of Meagan's score as the opposite of Justine's is -(-7) = 7, which is option D, where the double negative results in a positive score.
Explanation:
The trivia game scenario presents a situation where Justine and Meagan end up with opposite scores, with Justine losing 7 points and Meagan gaining the opposite. To express this numerically, if Justine's score change is represented as -7, then Meagan's score, being the opposite, is the negation of Justine's score, which is -(-7). This negation flips the sign of Justine's score change, resulting in a positive 7 for Meagan. Therefore, the correct way to represent that “the opposite of Justine’s score was equal to Meagan’s score” is -(-7) = 7.

Step-by-step explanation:
Volume of a cone= π*radius^2*height/3

The function f is defined by f(x)=5x+k, where k is a constant. Find k, if the value of f at x=2 is equal to 14.
WILL MARK BRAINLIEST!
Answer:
k = 4
Step-by-step explanation:
f(x)=5x+k
Let x =2
f(2) = 5*2 +k
f(2) = 10+k
We know f(2) = 14
14 = 10+k
Subtract 10 from each side
14-10 = 10+k-10
4 =k
We are given the function f(x) = 5x + k when k is a constant, x equals 2, and f(x) equals 14
Steps to solve:
14 = 5x + k; x = 2
~Substitute
14 = 5(2) + k
~Simplify
14 = 10 + k
~Subtract 10 to both sides
14 - 10 = 10 - 10 + k
~Simplfy
4 = k

Answer:
both rates of change equal the slope of the line (3/4)
Step-by-step explanation:
Part a)
We calculate the rate of change using the formula:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
for the first interval [0,6], we calculate the y-values at x=0 and x=6;
at x=0 : [tex]y=\frac{3}{2} (0)+2=2[/tex]
at x=6 : [tex]y=\frac{3}{2} (6)+2=11[/tex]
therefore, the rate of change in this interval is: [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{11-2}{6-0}=\frac{9}{6} =\frac{3}{2}[/tex]
For the second interval [-4,4], we calculate the y-values at x=-4 and x=4;
at x=-4 : [tex]y=\frac{3}{2} (-4)+2=-4[/tex]
at x=4 : [tex]y=\frac{3}{2} (4)+2=8[/tex]
therefore, the rate of change in this interval is: [tex]\frac{y_2-y_1}{x_2-x_1}=\frac{8-(-4)}{4-(-4)}=\frac{12}{8} =\frac{3}{2}[/tex]
Part b):
Notice that both rates of change equal the value of the slope of the linear function (3/2)
Describe the type of correlation indicated by each correlation coefficient r=0.875
Answer:
A strong correlation
Step-by-step explanation:
The closer the correlation coefficient is to the number 1 the stronger the correlation is.

trees. How much water is left in the rain barrel?
care sa nu mai

Answer:
27 gallons, 2 quarts
Step-by-step explanation:
The measurements are given in gallons and quarts. Lets convert everything to quarts.
We know:
4 quarts = 1 gallons
So,
Rain Barrel Capacity = 47*4 + 1 = 189 quarts
Jiko uses 12 gallon 2 quart to water flower garden = 12*4 + 2 = 50 quarts
Jiko uses 7 gallons 1 quarts to water trees = 7*4 + 1 = 29 quarts
He used up = 50 + 29 = 79 quarts
Remaining Water in Rain Barrel = 189 - 79 = 110 quarts
In gallons and quarts:
27 * 4 = 108 quarts
So, water left = 27 gallons, 2 quarts

J is the midpoint of CT CJ = 8x-5 and JT = 5x+4 find CT
The value of CT is 13x - 1.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment CT, where the length of line segment CT refers to the distance between its endpoints, C and T.
Given that J is the midpoint of CT
CJ = 8x-5 and JT = 5x+4
C______________J______________T
⇒ CT = CJ + JT
Since J is the midpoint of CT, So CJ = JT
⇒ CT = CJ + JT
Substitute the values of CJ = 8x-5 and JT = 5x+4 in the above equation,
⇒ CT= (8x-5)+(5x+4)
⇒ CT= 8x-5+5x+4
Rearrange the likewise terms, and apply the arithmetics operation,
⇒ CT = 8x + 5x - 5 + 4
⇒ CT = 13x - 1
Hence, the value of CT is 13x - 1.

Final answer:
To find the length of CT, solve the equation 8x-5 = 5x+4 to find x, then substitute the value of x into either CJ or JT to find the segment's length and double it.
Explanation:
The student is asking a geometry problem where they need to find the length of the segment CT given that J is the midpoint of CT with CJ being 8x-5 and JT being 5x+4. Since J is the midpoint, these two segments are equal in length, thus the equation to solve is 8x-5 = 5x+4.
To find the value of x, follow these steps:
Subtract 5x from both sides: 3x-5 = 4.Add 5 to both sides: 3x = 9.Divide both sides by 3: x = 3.Once x is found, substitute it back into either CJ or JT expression to find the length of one segment. Then, double that length to find CT, as CT is equal to 2 times CJ or 2 times JT.
A cylindrical tank is half-full of oil.
The cylinder has a base radius of 100cm. The height of the cylinder is 250cm.
1 litre= 1000cm^3
How many litres of oil are in a tank?
Round your answer to the nearest litre.
Answer:
3927 litres of oil to the nearest litre.
Step-by-step explanation:
The volume of the cylinder = π r^2 h
= π * 100^2 * 250.
When half full the volume is
1/2 * π * 100^2 * 250
= 3926991 cm^3 Dividing this by 1000:
= 3927 litres.
A cylindrical tank is half-full of oil.
There are 3928 liters of oil in the tank
Volume of CylinderVolume of cylinder is teh amount of material the cylinder holds. Volume is the density of the cylinder.
Volume Formula :

Height of the cylinder is 250 cm
Substitute all the values inside the formula
[tex]V=\pi (100)^2(250)\\V=2500000\pi[/tex]
Cylinder tank is half full of oil . To find half of the volume , we divide the volume by 2

Volume and Surface Area! 30 POINTS
Answer:
Volume: 5200 cubic centimeters
Surface area: 1520 square centimeters
Step-by-step explanation:
Volume = [1/2 x 5 x side x apothem] x height
(The apothem is that little 8 cm mark, the height is 26, the side is 10.)
Plug those values in:
V = 1/2 * 5 * s * a * h
