please help me with the question
Answer:
The answer is B.
Step-by-step explanation:
4x-7 = 2x+9
2x = 16
x = 8
And then we put x into the equations.
y = 32 - 7
y = 25
We then check it with the other equation just to make sure we are correct.
y = 16 +9
y = 25
Therefore, the answer is (8,25).
Find the surface area and volume of a cube with a cylinder cut out
Cylinder has 1m radius, cube: 6m
Answer:
247.42 m^2 to the nearest hundredth
Step-by-step explanation:
The surfaces area of the side of the cylinder = 2πrh
= 2π(1)(6)
= 12π m^2.
Now we need the surface area of the cube minus the 2 circles at each end of the cylinder
= 6^3 - 2πr^2
= 216 - 2π
So the required surface area
= 12π + 216 - 2π
= 217 + 10π
= 247.4159 m^2

A tree struck by lighting broke at a point 13 ft above the ground as shown. What was the height of the tree to the nearest tenth of a foot?
13² + 38² = c², so 169 + 1444 = c², 1613 = c², and 40.2 ≈ c.
Add this length to the height of the bottom tree: 40.2 + 13 = 53.2 ft.
The height of the tree was about 53.2 ft.

Asked about this yesterday, can someone please help! I really need to pass my math class!
Answer:
use area
Step-by-step explanation:
we can't use volume here since we are dealing with the outside part only
so area of a cylinder is =πr²h
our r represents the radius which is diameter/2
r=7.5/2
=3.75m
our h represents height which is 12.5m
so put in our formula
area = π×(3.75)²×(12.5)
=552.2330836m³

Answer:
A = 120 cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is:
A = 2(area of the top) + 2(area of the front) + 2(area of one side)
Substituting the values:
A = 2(20) + 2(16) + 2(24)
First, distributing:
A = 40 + 32 + 48
Then adding, giving your final answer

The ratio of the number of bananas to the number of apples at a fruit stand is 3:5. Moe says that the ratio is equivalent to 12:25.
Answer: Moe is wrong.
Step-by-step explanation:
Moe is incorrect because 25 divided by 5 equals 5 (constant of proportionality) but 12 divided by 3 does not equal 5 (it equals 4)
Identify the slope and y-intercept of each of the following lines. Then graph each line.
x = -7
Do I mark the graph attached?
Answer:
Below!
Step-by-step explanation:
Since there is a variable (x) on the L.H.S and a constant (-7) on the R.H.S, the line will be a vertical line intersecting the x-coordinate (-7).
~Graph attached
Determining the y-intercept of the line:
Since the line is a vertical line, it's y-intersept is undefined as it will never intersect the y-axis.
Determining the slope of the line:
To determine the slope of the line, pick any two points that is on the line.
⇒ (-7, 0) and (-7, 1)Using the slope formula (y₂ - y₁/x₂ - x₁):
⇒ 1 - 0/-7 - (-7)⇒ 1/-7 + 7⇒ 1/0∴ Any number divided by 0 is undefined
⇒ underfinedThus, the slope and the y-intercept are undefined.
So
line will be parallel to y axis
no y intercept as parallel to y axis means it will never intercept y axis
Slope will undefinedGraph attached

Help me I’ll give brianliest
Answer:
option D is a correct answer AA postulate
The two triangles are similar by the AA postulate
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be ΔEFG
Let the second triangle be ΔHJK
Now , the corresponding angles are
∠E = 25° = ∠H
So , the two angles are similar
And , the triangles are similar by the AA postulate
Hence , they are similar triangles

What is the sum of the diagonals in a rectangle whose area is 25v3 and whose width is 5?
Answer:
Sum of diagonals = 20 units
Step-by-step explanation:
[tex]A(rectangle)=25\sqrt 3\: units^2\\w(rectangle) =5\: units[/tex]
To find: Sum of diagonals
[tex]A(rectangle)=l(rectangle)\times w(rectangle) [/tex]
[tex]\implies l(rectangle)=\frac{A(rectangle)}{w(rectangle)}[/tex]
[tex]\implies l(rectangle)=\frac{25\sqrt 3}{5}[/tex]
[tex]\implies l(rectangle)={5\sqrt 3}\: units[/tex]
Let the diagonals of the rectangle be [tex]d_1\:\&\:d_2\: units[/tex]
Diagonals of a rectangle are equal in measure.
[tex]\implies d_1=d_2=\sqrt{l(rectangle)^2+w(rectangle)^2}[/tex]
(By Pythagoras Theorem)
[tex]\implies d_1=d_2=\sqrt{(5\sqrt 3)^2+(5)^2}[/tex]
[tex]\implies d_1=d_2=\sqrt{75+25}[/tex]
[tex]\implies d_1=d_2=\sqrt{100}[/tex]

What is the angle, in degrees, if the Area is 180 square miles and the radius is 42,240 feet?
Step-by-step explanation:
the area of a circle (all 360°) is
pi×r²
with r being the radius.
the area of a circle segment is just the corresponding fraction of the whole circle.
so the area of a segment of x degrees is
pi×r² × x/360
in our case we know
pi×42240² × x/360 = 180 mi²
we also know that there are 5280 ft in 1 mile.
so, the radius is actually
42240 / 5280 = 8 miles
and therefore our equation resulting in mi² has to use miles and not ft and has to look that way :
pi×8² × x/360 = 180 mi²
pi×64 × x/360 = 180
pi×64 × x = 180×360
pi×x = 180×360/64 = 1012.5
x = 1012.5/pi = 322.2887598...°
so, the angle of the segment of a circle with the area of 180 mi² and the radius of 8 mi is 322.2887598...°
For each figure, find x.
