Answer:
2.5
Step-by-step explanation:
8 times 4 is 32, and 80/32 is 2.5. When you have to find another measurement and you know 2 of them, you just have to divide the total of the 2 measurements with the volume. it would be 2.5 feet as the height.

Answer:
[tex] \purple { \bold{ a_{10}=161414428}}[/tex]
Step-by-step explanation:
Given sequence is: 4, 28, 196, 1372
28/4 = 7
196/28 = 7
1372/196 = 7
Since, the ratio of any two consecutive terms is same, so it is a geometric sequence.
Therefore,
Common ratio r = 7
First term a = 4
nth term of a geometric sequence is given as:
[tex]a_n=ar^{n-1} \\ \\\implies \\ \\ a_{10}=4.7^{10-1} \\ \\ a_{10}=4.7^{9} \\ \\ a_{10}=4.7^{9} \\ \\ a_{10}=4(40353607) \\ \\ \red{ \bold{ a_{10}=161414428}}[/tex]

Gabriel took a bath on Monday evening. He measured the water and found that he used 1,235l of water. On Tuesday, he took a shower and only used 478 litres of water. What was the difference in volumes? How much water did he used in total?
Answer:a)757liters
b)1, 713 litres
Step-by-step explanation:
Amount of water used on Monday =1,235l
Amount of water used on Tuesday =478liters
Difference in volumes for the two days
=1,235l -478l
=757liters.
Total amount of water used up in Total
1,235litres +478liters
=. 1, 713 litres.
Marty has a driveway that is 200 feet long. The tires on her car have a diameter of 18 inches. What is the fewest number of tire rotations a tire will make tot travel the entire distance of the driveway?
The the fewest number of tire rotations is 42 to travel the entire distance of the driveway.
It is given that the driveway that is 200 feet long and the tire diameter is 18 inches.
It is required to find the fewest number of tire rotations a tire will make to travel the entire distance of the driveway.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
Driveway length = 200 feet
Diameter of the tire = 10 inches
For converting it to feet divide by 12.
Now the diameter of tire = 18/12 = 1.5 feet
Radius of the tire = 0.75 feet
We know the perimeter of the circle:
[tex]\rm P = 2\pi r[/tex]
P = 2(π)(0.75)
P = 4.71 feet ( π =3.14 and P = 0.75)
[tex]\rm number \ of \ tire \ rotations = \frac{Driveway \ length}{Perimeter \ of tire}[/tex]
[tex]= \frac{200}{4.71}[/tex]
Number of tire rotation = 42.462 ≈ 42
Thus, the the fewest number of tire rotations is 42 to travel the entire distance of the driveway.

Raj is 53.56 inches tall. He is 1.3 times as tall as his younger sister. How tall is Raj's younger sister
Answer:
41.2 inches tall
Step-by-step explanation:
53.56 / 1.3 = 41.2
Step-by-step explanation:
Let Raj's sister's height be x
53.56= 1.3x
= 53.56/1.3=x
= 41.2=x

PLZZZ HURRYY. i will thank you. Q- Explain the transformations that map the polygon A to polygon B.
2 The length of this rectangle is x cm.
a The width of the rectangle is 2 cm less than the length.
Write down an expression for the width of the rectangle, in centimetres.
b The perimeter of the rectangle is 84 cm. Write down an equation to show this.
c Solve the equation.
d Find the area of the rectangle.
Answer:
a. The width of the rectangle is x-2cm
b. length is 21.5 cm and breadth is 19.5cm
c. area is 419.25 cm sq.
Step-by-step explanation:
Let the length be x and the breadth be x-2
perimeter = 84 = 2(l+b) = 2×(x+x-2)
2×(2x-2)=84
4x-2 = 84
4x = 86
x= 86/4
x= 21.5
length is 21.5 and breadth is 21.5-2 = 19.5
area = l×b
= 21.5 ×19.5
= 419.25cmsq.

find the area of the regular polygon with the given apothem a and side length s. a=28. s=18.2 round to the nearest decimal place as needed
The formula for finding the area of any regular polygon if you know the length of one side and the apothem: A = (n × s × a)2 A = ( n × s × a ) 2 , where n is the number of sides, s is the length of one side, and a is the apothem.
Amy wrote a 10 sided die numbered one through 10 what is the probability that she will hold a number divisible by four
Answer:
2/10 or 20%
Step-by-step explanation:
Because 4 and 8 are the only numbers 1-10 that are divisible by four.
This would give Amy a 2/10 chance of rolling a number divisible by 4.
To turn 2/10 into a percent, the denominator has to be 100 so if you multiply 10 by 10 you will get 100, you will also have to multiply 2 by 10 to get 20 and you will get 20/100
20/100 is equal to 20%
Therefore your answer would be 2/10 or 20%

Answer:
Number of boys who attended the community service event = 10
Step-by-step explanation:
Let [tex]x[/tex] denotes number of girls and [tex]y[/tex] denotes number of boys.
Twenty-six students attended the community service event.
So,
[tex]x+y=26[/tex]
The number of girls was 4 fewer than twice the number of boys.
[tex]x=2y-4[/tex]
Put [tex]x=2y-4[/tex] in [tex]x+y=26[/tex]
[tex]2y-4+y=26\\3y=26+4\\3y=30\\y=10[/tex]
So,
Number of boys who attended the community service event = 10

Answer:
MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8

Is y proportional to x and y? Why or why not
Answer:
X is directly proportional to y means the value of x is dependent on the value of y. y may not be dependent on x in this case.
Y is directly proportional to x means the value of y is dependent on the value of x. Same as above, in this case, the value of x may not depend on y.

Step-by-step explanation:
Find the slope and the y-intercept of the line.
5x-4y=-8
Write your answers in simplest form.
Answer:
The slope is 5/4 and the y-intercept is 2.
Step-by-step explanation:
5x-4y=-8
4y=5x-(-8)
4y=5x+8
y=5/4x+8/4
y=5/4x+2
y=mx+b where m=slope and b=y-intercept.
X, Y and Z are three points on a map. Y is 43km and on a bearing of 041° from X. Z is 67km and on a bearing of 117° from X. Calculate the distance between Y and Z rounded to 1 DP
Answer:
70.3km
Step-by-step explanation:
When the bearings are visualized and the points connected as a triangle, The angle x would be the difference of the both bearings from x
i.e 117-41 = 76
Using cosine rule,
YZ²= 43² + 67² - 2 x 43 x 67
cos76
YZ= √4944
= 70.3

A. The data represent an exponential function because there is a

B. The data represent a linear function because there is a common
difference of 9
C. The data represent an exponential function because there is a
5
common ratio of -
D. The data represent a linear function because there is a common
difference of -9.
Answer:-8
Step-by-step explanation:
The data represent a linear function because there is a common difference of -9.
What is a linear function?The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.
From the table, we have the following highlight :-
As the values of x increase by 1, the values of y decrease by 9
A decrement of 9, means -9
This means that, the common difference is -9.
Only a linear function can have a common difference.
Hence, the true statement is (b)
