Answer:
240.6 ft is your answer of your question.
Answer:
240.6 feetStep-by-step explanation:
to understand thisyou need to know about:trigonometryPEMDASlet's solve:to find x we will use cos function
[tex] \quad \: \cos( \theta) = \dfrac{adj}{hypo} [/tex]
substitute the value of [tex]\theta[/tex] and adj:
[tex] \quad \: \cos( {67}^{ \circ} ) = \dfrac{94}{x} [/tex]
cross multiplication:
[tex] \quad \: x\cos(67^{\circ})= 94 [/tex]
divide both sides by cos(67°) :
[tex] \quad \: \dfrac{x \cos( {67}^{ \circ} ) }{ \cos( {67}^{ \circ} ) } = \dfrac{94}{ \cos( {67}^{ \circ} ) } \\ \therefore \: x = 240.6[/tex]

The measure of ⏜ is 161°, and the measure of ⏜ is 107°.
What is the measure of ∠ ?
Answer:
m<AEB = 46°
Step-by-step explanation:
Given:
Arc AD = 161°
Arc BC = 107°
Required:
m<AEB
Solution:
Vertex angle = ½(sum of intercepted arcs) => Theorem for angle inside a circle and its intercepted arcs)
This:
m<AED = ½(AD + BC)
m<AED = ½(161 + 107) => Substitution
m<AED = ½(268) = 134°
✔️m<AEB = 180° - m<AED => Linear pair theorem
m<AEB = 180° - 134° => substitution
m<AEB = 46°

A balloon lifts off the ground and reaches a height of 200m. The total mass of the balloon is 1000 kg. What is the GPE of the balloon?
Answer:
1,960,000Joules
Step-by-step explanation:
Gravitational Potential Energy is expressed as;
GPE = mgh
m is the mass
g is the acceleration due to gravity
h is the height
Given
m = 1000kg
h = 200m
g = 9.8m/s
Substitute;
GPE = 1000 * 9.8 * 200
GPE = 9800 * 200
GPE = 1,960,000Joules
Hence the GPE of the balloon is 1,960,000Joules

-9.1 < x -6.3
Answer:
is that the whole math question? I need a number after the < to solve this
help me pretty please <3 (brainliest)
Answer:
The value is 0.025
Step-by-step explanation:
We get the z-score that is equal to the given value
Mathematically we have this as:
z-score = (x-mean)/SD
x = 93
mean =79
SD = 7
So we have the z-score as;
z-score = (93-79)/7 = 14/7 = 2
So we want to calculate the probability equal to the calculated z-score value of 2
Using the standard normal distribution table, we have this value as;
1 - 0.975= 0.025
The foot of a ladder is placed 18 feet from a wall. If the top of the ladder
rests 24 feet up on the wall, find the length of the ladder.
26 feet
27 feet
29 feet
O 30 feet
Answer:
I'm not sure
I think its 30 or 26
Step-by-step explanation:
Answer:
30 feet
Step-by-step explanation:
The ladder laying against the wall will create a right triangle.
The side lengths will be 18 and 24 and you will solve for the hypoteneuse which will be the length of the latter.
You can use the pythagorean theorm so
[tex]a^{2} +b^{2} =c^{2}[/tex] so you plug in the values
[tex]18^{2}+24^{2} =c^{2} \\324+576=c^{2} \\900=c^{2} \\\sqrt{900} =\sqrt{c^{2} } \\30=c[/tex]
Solve for x based on the following system of equations:
x + y = 5
2x + 3y = 20
-10
-5
-2
5
10
Answer:
x = -5
Step-by-step explanation:
x + y = 5 can be also written as 3x + 3y = 15 by times 3 on both side, let it be equation (1), then let 2x + 3y = 20 be equation (2), then use equation (2) - (1), can get (2x - 3x) + (3y - 3y) = 20 - 15 ---> -x = 5, then x = -5.

Answer:
Do you have a diagram to follow?
It will much help, and easier for answering.
The radius of the other similar circle is, 6 inches
What is a circle?In mathematics, the circle is a two dimensional rounded figure which has no corner edges.
Standard form = (x - a)² + (y - b)² = r²
Angle = Arc / Radius
Given that,
The two arc lengths for the circles are equal
One circle has a radius of 8 inches and a shaded sector with an angle measure of 90 degrees
The second circle has a shaded sector with an angle measure of 120 degrees
The radius of second circle = ?
α = 90°
It is known that,
π radian = 180°
1° = π/180 radian
Now,
α = 90 × π/180
= π/2
β = 120°
= 120 × π/180
= 2π/3
In Circle 1,
Angle = Arc / Radius
π/2 = Arc/8
Arc = 4π
In both the circles, length of arc is same,
In Circle 2,
Angle = Arc / Radius
2π/3 = 4π/Radius
Radius = 6
Thus, the radius of second circle is 6 inches

A right square pyramid has a base with sides that are 2 inches in length and a slant height of 7 inches. If the lengths of the sides of the base and the slant height are multiplied by 7, by what factor is the surface area multiplied? A. 7 B. 14 C. 28 D. 49
Answer:
Step-by-step explanation:
base b = 2 in
slant height L = 7 in
lateral area = 4·½bL = 4·½·2·7 = 28 in²
base area = b² = 4 in²
surface area = 28+4 = 32 in²
If b = 14 and L = 49:
lateral area = 4·½·14·49 = 1372 in²
base area = 196 in²,
and surface area = 1372+196 = 1568 in²
The surface area has multiplied by 49.

find the values of the variables
Answer:
x = 31 and y= 11
Step-by-step explanation:
Since sum f angles on a straight line is 180°, hence;
2x+8+3x+17 = 180
Collect like terms
5x+25 = 180
5x = 180-25
5x = 155
x = 155/5
x = 31°
Similarly;
3x+17+5y+15 = 180
Substitute x = 31 into the equation
3(31)+17+15+5y = 180
93+32+5y = 180
125+5y =180
5y = 180-125
5y = 55
y = 55/5
y = 11°
Hence x = 31 and y= 11
