A 10 foot ladder is leaning up against a building. If the ladder makes a 46° angle
with the ground. How far up the building will it reach? Round your answer
to three decimal places.
Answer:
7.193 ft
Step-by-step explanation:

| 46° \
---------------------
For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.
sin A = opp/hyp
sin 46° = h/10
h = 10 sin 46°
h = 7.193
Answer: 7.193 ft

Find the volume. Round to the nearest hundredth.
Answer:
261.80 mm³
Step-by-step explanation:
the volume is 1/3 of the volume of a cylinder with the same measurements (ground area times height).
so, v = pi × r^2 × h × 1/3
r=5
h=10
v = pi × 5^2 × 10 × 1/3 = pi × 250/3 = 261.80 (261.7993878...)
The solar array panels on the outside of the International Space Station are about 240 feet long by 40 feet wide. What is the area of the top face of one solar array panel? Show your work, including the formula used to solve the problem.
Answer:
Area cover by solar panel to face = 9,600 feet²
Step-by-step explanation:
Given:
Length of Solar panels = 240 feet
Width of Solar panels = 40 feet
Find:
Area cover by solar panel to face
Computation:
Area of rectangle = Length × Width
Area cover by solar panel to face = Length of Solar panels × Width of Solar panels
Area cover by solar panel to face = 240 × 40
Area cover by solar panel to face = 9,600 feet²
Answer:
Area cover by solar panel to face = 9,600 feet², The panels are about 340 feet Long, and 40 feet Wide. The area of this rectangle is a Length x Width.

Answer
a. The volume is multiplied by 4
b. The volume is doubled
Explanation
a. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the radius is doubled, the new volume will be [tex]\pi (2r)^2h/3[/tex], which is equal to [tex]4\pi r^2h/3[/tex]. This means that the volume is multiplied by 4.
b. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the height is doubled, the new volume will be [tex]\pi r^2(2h)/3[/tex], which is equal to [tex]2\pi r^2 h/3[/tex]. This means that the volume is multiplied by 2.
You buy a video game and pay for it with a $50 bill. Write an expression that can be used to find out how much change you should receive.
Answer:
The answer is given below.
Step-by-step explanation:
Let us assume the cost of the video game be x
There should be two chances
The first one is
that the cost of the video game should be equivalent to the amount given
SO
The return is $0
The second one is
When the cost of the video game is less than the amount you pay
SO, the return change is
= $50 - x

Answer:
b² - 4ac > 0
Step-by-step explanation:
Conditions for the discriminant
• If b² - 4ac > 0 then 2 real and distinct roots
• If b² - 4ac = 0 then 2 real and equal roots
• If b² - 4ac < 0 then no real roots
Here the roots are x = 0 and x = 4
That is 2 real and distinct roots , then
b² - 4ac > 0

Karissa made a giant circular sugar cookie for dessert. She wants to frost it. The cookie has a 14 inch diameter. How many square inches of frosting are needed to cover the entire top of the cookie?
Answer:
153.86in^2
Step-by-step explanation:
Area of a circle = πr²
Where : = π = pi = 3.14
R = radius = 14/2 = 7
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
7² x 3.14 = 153.86
A radius is half of the diameter
3 1/3 + (-2 1/4) + 1 /56 = ???
Answer:
1.10119047619 use first 3 digits for answer
Answer:
1 17/168
Step-by-step explanation:
3 1/3 is the same as 3 4/12
-2 1/4 is the same as -2 3/12
3 4/12 + (-2 3/12) = 1 1/12
1 1/12 + 1/56 = 13/12 + 1/56
we can use 168 as a common denominator to get:
13/12 = 182/168
1/56 = 3/168
add the above together to get 185/168 which is 1 17/168

In the diagram below, what is the measure of angle 4
Answer:
Angle 4 equals to 120 degrees
Step-by-step explanation:
120 degrees is an obtuse angle
Answer:
∠ 4 = 123°
Step-by-step explanation:
The sum of the 3 angles in the triangle = 180°
sum the 3 angles and equate to 180
9x - 6 + 6x - 1 + 82 = 180
15x + 75 = 180 ( subtract 75 from both sides )
15x = 105 ( divide both sides by 15 )
x = 7
Then
9x - 6 = 9(7) - 6 = 63 - 6 = 57
∠ 4 and 9x - 7 are adjacent angles and sum to 180°, then
∠ 4 + 57° = 180° ( subtract 57° from both sides )
∠ 4 = 123°

Given point A (3, 8) and point B (-5, 1). Find the following: a.) The coordinates of the midpoint of segment AB. Write your answer in this form: (x, y) (7 points) b.) Using the distance formula, find the length of segment AB. Round to the nearest hundredth. (7 points) c.) Find the slope of segment AB. (if your answer is a fraction, use the "/" symbol) (7 points)
Answer:
Mid point:
[tex] = ( \frac{3 + - 5}{2} , \: \frac{1 + 8}{2} ) \\ = ( - 1, \: 4.5)[/tex]
distance:
[tex] = \sqrt{ {( - 5 - 3)}^{2} + {(1 - 8)}^{2} } \\ = \sqrt{64 + 49} \\ = \sqrt{113} \\ = 10.6 \: units[/tex]
slope:
[tex] = \frac{1 - 8}{ - 5 - 3} \\ = \frac{ - 7}{ - 8} \\ = \frac{7}{8} [/tex]

Find the volume of the cone. Round your answer to the nearest tenth.
The volume of the cone is about
cubic yards.
PLEASE HELP
9514 1404 393
Answer:
115.5 cubic yards
Step-by-step explanation:
The volume is given by the formula ...\
V = 1/3πr²h
Here the diameter is 7 yards, so the radius is 3.5 yards. The volume is then ...
V = (1/3)π(3.5 yd)²(9 yd) = 36.75π yd³ ≈ 115.454 yd³
The volume of the cone is about 115.5 cubic yards.
Jada walks up to a tank of water that can hold up to 15 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 12 gallons of water. Five minutes later, the tank contains 10 gallons of water.
Type your answers in the blanks below.
At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
How many more minutes will it take for the tank to drain completely?
________minutes
How many minutes before Jada arrived was the water take completely full?
_________ minutes
Answer:
A) -2/5 gal/min
B) 25 minutes
C) 7.5 minutes
Step-by-step explanation:
A) We are told that the tank contains 12 gallons of water when Jada first sees it.
5 minutes later, it loses two gallons to become 10 gallons.
Thus, rate at which the amount of water in the tank changing = -2/5 gal/min
B) After 5 minutes it contains 10 gallons. Since it drains at 2/5 gal/min, let us say the time to finish draining all is x, thus;
2/5 • x = 10
x = 10 × 5/2
x = 25 minutes
C) When full, it can hold up to 15 gallons. This is 3 more than the 12 she saw when she arrived.
Thus;
2/5 • y = 3
y = 5 × 3/2
y = 7.5 minutes
