Answer: The answer is five
Step-by-step explanation:
Set y = z
50x + 75 = 65x
Subtract 50x from both sides
50x (-50x) + 75 = 65x (-50x)
75 = 15x
Divide both sides by 15
75 (/15) = 15x (/15)
5 = x
And there we have it, x = 5! So it takes 5 hours of work for each to cost the same.
Answer: (Y - 100)/ 45 =No of hours
where y is the full payment
Step-by-step explanation:
Charges per hour plus visit is 45+100 where 100 Is fixed
2hr is (45 × 2) +100
Payment y for Xhrs= 45X + 100
Y =45X + 100
Y -100 =45X
Y -100/45 = X
Plss help i will give 100 for the right answer
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.

What is the best name for angle Y?
Triangle X Y Z. Side X Z extends to form angle W.
exterior angle
alternate interior angle
remote interior angle
adjacent interior angle
Answer:
Exterior angle.
Step-by-step explanation:
by my analysis
if hey said triangle XYZ
it should mean each exterior angle is named either X, Y, or Z.
so angle Y should be an exterior angle (outside angle).
but the angle formed by X and Z will be an interior angle (inside angle).
Hope this helps .

The answer is C: Remote Interior Angle

Step-by-step explanation:
Lets look at all the answer choices:
A and looks like a little number.
B said 7. 7 x 16 = 122 7 x 12 = 84.
122 + 56 = 178. 140 + 84 = 224.
B is incorrect
C said 21. 21 x 16 = 336 21 x 12 = 252
336 + 56 = 392 and 140 + 252 = 392
C is the correct answer.

3/8 divided by 1/7
Answer:
[tex]2\frac{5}{8}[/tex], or [tex]\frac{21}{8}[/tex]
Explanation:
Use the Keep Change Flip method. Change the sign to multiplication and flip the second fraction. [tex]\frac{3}{8}[/tex] × [tex]\frac{7}{1}[/tex]
Multiply the numerators and the denominators separatley. [tex]\frac{3}{8}[/tex]×[tex]\frac{7}{1}\\[/tex]=[tex]\frac{21}{8}[/tex]
This cannot be simplified further, but it can be converted to a mixed number (as opposed to an improper fraction). [tex]\frac{21}{8} =2\frac{5}{8}[/tex]
If the diameter of a youth baseball is 2.8 inches and the diameter of an adult softball is 3.8 inches, what is the approximate difference in their volumes? use 3.14 for pi. round to the nearest tenth. recall the formula sphere volume = four-thirds pi r cubed. 1.0 cubic inch 17.2 cubic inches 40.2 cubic inches 137.8 cubic inches
The approximate difference in their volumes is 17.2 cubic inches
Volume of a sphereA sphere is a round solid figure, with every point on its surface equidistant from its centre.
The formula for calculating the volume of a sphere is;
V = 4/3πr³
where:
r is the radius of the sphere
Given the following
diameter of youth ball =2.8in
radius of youth ball r = 1.4in
diameter of adult ball =3.8in
radius of adult ball R = 1.9in
Determine the difference in volume
D = 4/3π(R³ - r³)
Substitute
D = 4/3π(1.9³ - 1.4³)
D = 4/3π(4.115)
D =17.2 cubic inches
Hence the approximate difference in their volumes is 17.2 cubic inches

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
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:
its either 2 or 4 because a triangle can't change its shape it need to be the same shape
Answer:
2, 3, and 4.
Step-by-step explanation:
The only answer that would result in a non-congruent triangle would be Option 1. It is asking you to dilate by a scale factor of 2 which would make the triangle 2 times bigger. In that case, the triangle to not be congruent.
Reflections, Rotations, and Translations do not change the size of the triangle which means it remains congruent.

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...°

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

[tex] \frac{v \times 7}{7} = 3 \times 7 \\ [/tex]
[tex]v = 21 \\ [/tex]
Answer:
Option B is correct i.e. 21Step-by-step explanation:
In the question we're provided with an equation that is :
v/7 = 3And we are asked to find the solution for the equation .
Solution : -
[tex] \longrightarrow \: \frac{v}{7} = 3[/tex]
Multiplying by 7 on both sides :
[tex] \longrightarrow \: \frac{v}{ \cancel{7} }\times \cancel{7} = 3 \times 7[/tex]
On further calculations , we get :
[tex] \longrightarrow \: \blue{\boxed{v = 21}}[/tex]
Therefore , solution for equation is 21 .That means option B is the correct answer.Verifying :
We are verifying our answer by substituting value of v in the equation given in question :
[tex] \longrightarrow \: \frac{v}{7} = 3[/tex]
Putting value of v :
[tex] \longrightarrow \: \cancel{\frac{21}{7}} = 3[/tex]
By dividing 21 with 7 , we get :
[tex] \longrightarrow \:3 = 3[/tex]
[tex] \longrightarrow \: L.H.S=R.H.S[/tex]
[tex] \longrightarrow \: Hence , \: Verified.[/tex]
Therefore , our answer is valid .#Keep Learningi) Given that a = 1, b = 3, c = 7, evaluate abc
