Answer:
9.936
Step-by-step explanation:
V = Bh
B = base
base = Lengh x width
base = 4.8 x 2.3
base = 11.04
V = 11.04h
H = height
H = .9
V = .9 x 11.04
V = 9.936
Answer:
9.936 m³
Step-by-step explanation:
A cylinder has a radius of 4.5 inches and a height of 15 inches. If the radius is doubled, how would it affect the original volume of the cylinder?
Answer:
The volume will be increased 4 times.
Step-by-step explanation:
Short mathy expl:
If the radius is "doubled" that is 2 times bigger. But in the volume formula, the radius is squared. So 2 times bigger AND squared makes it FOUR times bigger.
See the volume calculations:
original--
Vol = pi•r^2•h
= (3.14)•4.5^2•15
= 953.775
new/bigger radius--
Vol = 3.14•9^2•15
= 3815.1
So when the radius is doubled, going from 4.5 to 9, the volume goes from 953.775 to 3815.1
3815.1 is 4 times 953.775
If MNPQ is a quadrilateral, what is angle MQP
Answer:
62°Step-by-step explanation:
angle M = angle Q
(An isosceles trapezoid can be defined as a trapezoid in which non-parallel sides and base angles are of the same measure.)
so
Angle Q = 30 + 32
Angle Q = 62°

Answer:
It will be in quadrant one if it flips across the x-axis becuase the x-axis will take it toward the right which is the quadrant 1
Step-by-step explanation: hope this helps
Answer:
Quadrant III
Step-by-step explanation:
When you reflect across the X-axis, you flip it over the horizontal line. The Quadrants are numbered like this : 2 1
3 4
So it will be in Quadrant III

I need help. I'm desperate. Find the area of the shaded region, round to the nearest tenth. I will give brainliest
the answer is NOT 17.4
ANSWER
A. (243pi+162) ft^2
EXPLANATION
The area of the shaded region is the sum of the area of the major sector and the area of the isosceles triangle.
Area of major sector
[tex]=\frac{360-90}{360}[/tex] × [tex]\pi[/tex] × [tex]18^2[/tex][tex]=243\pi ft^2[/tex]
The area of the isosceles triangle is calculated using the formula;
[tex]=\frac{1}{2}r^2sin(0)[/tex]
[tex]=\frac{1}{2}[/tex] × [tex]18^2[/tex] [tex]sin(90)[/tex][tex]=162ft^2[/tex]
The area of the shaded region
[tex]=(243\pi +162)ft^2[/tex]
The correct answer is A.
The volumes of two similar solids are 210 m3 and 1,680 m3. The surface area of the larger solid is 856 m2. What is the surface area of the smaller solid? 107 m2 214 m2 1034 m2 6848 m2.
The surface area of the smaller solid according to the task content is; 107m²
What is the surface area of the smaller solid?It follows from task content that the two solids are similar. On this note, the same formula applies for calculating their areas and volume.
Since, surface area is directly proportional to the volume in both shapes;
The surface area of the smaller solid is;
A = (210 × 856)/1680
A = 107m².

4) Solve for x and find the measure of angle zxy
Answer:
Angle zxy = 55 degrees, x = 12
Step-by-step explanation:
Since the angle WXY is labeled as a right angle from the square in the angle, and angle WXZ is 35 degrees, we know that angle ZXY must be 55 degrees, because 55+35 = 90. Then to solve for x, we use the measure of angle ZXY to construct the equation 4x+7 = 55. subtract 7 from both sides to get 4x = 48, then divide both sides by 4 to arrive at the answer of x = 12.

Answer:
C.
Step-by-step explanation:
which functions have a maximum and are transformed to the left and down of the parent function, f(x)=x²? check all that apply
p(x)=14(x+7)²+1
q(x)=-5(x+10)²-1
s(x)=-(x-1)²+0.5
g(x)=2x²+10x-35
t(x)=-2x²-4x-3
Answer:
q(x) and t(x)
Step-by-step explanation:
p(x) has no maximum (bc it's an upward parabola) and is shifted up from the parent equation
q(x) has a maximum (downward parabola) and is shifted left and down from the parent equation
s(x) has a maximum (downward parabola), but is shifted right and up of the parent equation
g(x) has no maximum (upward parabola) but is shifted left and down
t(x)has a maximum (downward parabola) and is shifted left and down from the parent equation

2(x-18)+ 3x = 24
Answer:
x = 12
Step-by-step explanation:
2(x-18)+ 3x = 24
distribute the 2
2x - 36 + 3x = 24
combine like terms
5x - 36 = 24
+ 36 on both sides
5x = 60
divide by 5
x = 12
A rectangular garden 50 m long by 34 m wide is surrounded by a sand path of uniform width. Calculate the width of this path if it is known that it has an area of 540 cm2.
Considering a width x of the sand path, we have a larger rectangle of dimensions 50+2x by 34+2x, as indicated in the figure. Now, the area of the sand path is expressed.
[tex]\boldsymbol{\sf{ (50+2x)(34+2x)-50\times 34=540\Longrightarrow\quad 0=4x^2+168x-540 }}[/tex]
[tex]\boldsymbol{\sf{ 0=4(x^2+42x-135)=4(x-3)(x+45) }}[/tex]
Therefore, the path is 3 m long.

The diameter of a circle is 14 kilometers. What is the circle's area? d=14 km Use 3.14 for . square kilometers
Answer:
153.86
Step-by-step explanation:
The equation for the area of a circle is A = πr^2. The "r", in this sense, is the radius, which is half of the diameter. If the diameter is 14 then the radius is 7. The radius will then be squared to create 49, as 7 multiplied by itself is 49. The number must then be multiplied by π, or in this case, 3.14. This will give you the answer of 153.86.

then
[tex]\frac{tan^2x+1}{1+cot^2x}[/tex]
