Answer:
11cm
Step-by-step explanation:
diameter = 16, r = 8 (16÷2)
π = 3.142
V=πr2h
2211.68 = π x 8^2 x h
2211.68 = 3.142 x 64 x h
2211.68 ÷ 64 ÷ 3.142 = h
h = 10.9986
= 11 cm (round off to nearest cm)
To check and confirm
V=πr2h
3.142 x 64 (8^2) x 10. 9986 = 2211.68
Square will be centered at the origin on the coordinate plane. A rigid transformation of preimage is performed to image ′′′′. Determine which of the following characteristics or corresponding parts will not remain the same.
A. The measure of ∠′ after a reflection across the line y = x
B. The coordinates of A' after rotations of 360°
C. The coordinates of B' after a translation of 3 units left and 2 units up
D. The perimeter of square A'B'C'D'
Answer:c
Step-by-step explanation:
Transformation involves changing the position of a shape in a coordinate plane.
The corresponding parts that will not remain the same is (c) the coordinates of B' after a translation of 3 units left and 2 units up
Reflection is a rigid transformation;
This means that, options (a) and (d) will remain unchanged for the image and the pre-image of square ABCD
Rotating a shape 360 degrees will return the shape to its original position.
This means that: (b) will remain unchanged
The coordinates of B' after translation will not remain the same, because the points will move to (x + 3, y + 2).
Hence, option (c) is true

A grocery store sells a case of 24-500ml bottles of water for $2.99. They also Sell a case of 6-1.5 L bottles for $2.99. Which bottles are the best by? How much are you saving per liter?
Answer:
24 - 500ml bottles; $.08 per L
Step-by-step explanation:
1 liter = 1,000 ml
so 500ml = .5 L
Now compare the amount of water: 24 at .5L = 12L
6 at 1.5L = 9L
So the 12L /24 = .5 L per bottle cost about $.25
1.5L/ 6 = .25 L per bottle cost about $.33

Answer:
5025.41
Step-by-step explanation:
$50.50 and 16 cents - $40.50 and 9 cents = $40.00 and 10 cents per mile. For x miles, we multiply $40.00 and 10 cents by x miles.
Also, we could convert dollars to cents by multiply it by 100 Since $1 =100 cents.
5066 - 40.59 cents = 5025.41 cents. For x miles, 5025.41 cents.

Find the perimeter of the figure below. Find the area of each of the three shapes that make up the composite figure. Find the total area of the composite figure below. Be sure to include the proper units.
Step-by-step explanation:
the perimeter =
4+4+6+4.5+2+4+4+2 =
30.5 cm
the area of:
• the bigger rectangle = 6×4 = 24 cm²
• the smaller triangle = 4×2 = 8cm²
• the triangle = ½×2×4 = 4cm²
the total area = 24+8+4 = 36cm²
Write the equation of a line that is perpendicular to y = 1/2x - 7 with a y-intercept of 15.
What is the perpendicular slope?
What is the new equation?
Answer:
m = -2
y = -2x + 15
Step-by-step explanation:
so it's asking for the perpendicular slope so perpendicular means negative reciprocal so the negative reciprocal of 1/2 is -2
and since the question has already provided the y intercept, just write out the new equation in slope intercept form so y = -2x + 15. hope this helps

4.what equation passes through the 2 points
(2, 1) and (6, 9)
Answer:
y = 2x - 3
Step-by-step explanation:
Finding the slope:
[tex]\frac{y2-y1}{x2-x1}[/tex]
= (9-1)/(6-2)
= 8/4
= 2
Slope: 2
Substituting this value into the equation 'y=mx+c':
y = 2x + c
Substituting any points (in this case, (2,1)) into the above equation:
1 = 2(2) + c
1 = 4 + c
c = 1 - 4
c = -3
Hence,
y = 2x - 3

Answer:
y=2x-3
Step-by-step explanation:
first put in the equation:
[tex]\frac{9-1}{6-2}[/tex] and you get 8/4 which equals 2. so this is your slop.
now put in this equation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
so you put in (2-1)
[tex]y-1=2(x-2)[/tex]
and you get
y-1=2x-4
and if u add 1 to both sides you get y=2x-3

Given complex number is

So, on rationalizing the denominator, we get
[tex]\rm \: = \: \dfrac{3 + 2i}{ - 2 + i} \times \dfrac{ - 2 - i}{ - 2 - i} [/tex]
[tex]\rm \: = \: \dfrac{ - 6 - 3i - 4i - {2i}^{2} }{ {( - 2)}^{2} - {i}^{2} } [/tex]
We know,
[tex] \rm \red\longmapsto\:\tt{ {i}^{2} \: = \: - \: 1 \: } \\ [/tex]
So, using this, we get
[tex]\rm \: = \: \dfrac{ - 6 - 7i - 2( - 1) }{ 4 - ( - 1)} [/tex]
[tex]\rm \: = \: \dfrac{ - 6 - 7i + 2}{ 4 + 1} [/tex]

Given that x = 2.2 correct to 1 decimal place, find the interval that
contains the value of 4x + 3. Give your answer as an inequality.
Answer:
11.8
Step-by-step explanation:
The solution is 11.0 < 4x + 3 < 12.0
The inequality equation is 11.0 < 4x + 3 < 12.0 , where the value of the equation 4x + 3 = 11.8 , when x = 2.2
What is an Inequality Equation?
Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the equation is P = 4x + 3
The value of x = 2.2
Correcting the value of x to one decimal place , we get x = 2.2
Substitute the value of x in the equation , we get
P = 4x + 3
when x = 2.2
P = 4 ( 2.2 ) + 3
P = 8.8 + 3
P = 11.8
Now , the inequality equation is 11.0 < 11.8 < 12.0
Hence , the inequality equation is 11.0 < 4x + 3 < 12.0 , where 4x + 3 = 11.8
