Answer:
6955 ftStep-by-step explanation:
Refer to attached. Point J, segment BJ and angle measures added.Step 1, find BJ
BJ / AB = sin 20° ⇒ BJ = AB sin 20° ⇒ BJ = 600 sin 20° ≈ 205.2 ftStep 2, find BP
BJ/BP = cos 75° ⇒ BP = BJ / cos 75° ⇒ BP = 205.2/cos 75° ≈ 792.8 ftStep 3, find PQ
PQ/BP = sin 35° ⇒ PQ = BP sin 35° ⇒ PQ = 792.8 sin 35° ≈ 454.7 ftStep 4, find the elevation of peak P

What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that Abigail paid $62.00 for 8 friendship bracelets. Each bracelet cost an equal amount.
Cost of 8 friendship bracelets = $62.00
Therefore,
Cost of 1 friendship bracelets = $62.00/ 8
Cost of 1 friendship bracelets = 7.75
The cost of 1 friendship bracelets is $7.75

Write the slope-intercept form of the equation of a line with a slope of -5/8 that passes through the point (-14,6)
Answer:
y = -5/8x - 11/4
Step-by-step explanation:
Since we already know the slope which is -5/8. This will be the m in the equation.
To find the y-intercept, plug the coordinates into the equation, which is
y= -5/8 + b
6 = -5/8(-14) + b
6 = 35/4 + b
= -11/4 = b

Maya and Reginald are installing hardwood flooring. Maya can install flooring in a room in 4 hours. Reginald can install flooring in a room in 3 hours. How long would it take them if they worked together?
Answer:
1 hour 42 minutes approx
Step-by-step explanation:
Given data
Mayas work rate= 1/4 room per hour
Reginald work rate= 1/3 room per hour
Let the total time taken for both of them be T
Hence their combined work rate
1/4+1/3= 1/T
3+4/12=1/T
7/12=1/T
T= 12/7
T= 1.7 hours
Hence it will take them 1 hour 42 minutes approx

Slope: 1
Step-by-step explanation:
(9,0) and (0, -9)
m= (y2-y1)/(x2-x1)
m= (-9 - 0)/ (0 - 9)
m= (-9)/(-9)
m = 1
Answer:
Solution given:
coordinates are
(x1,y1)=(9,0)
(x2,y2)=(0,-9)
we have
Slope =[tex] \frac{y2 - y1}{x2 - x1} [/tex]
[tex] = \frac{ - 9 - 0}{0 - 9} [/tex]=1
The slope of a line is 1.

Answer:
Approximately 460 ft
Step-by-step explanation:
In any question where we have:
A right triangleAn given angle, andA given sideAnd we're asked to find:
A missing sideWe're gonna be using some trigonometry. The first question we've gotta ask is what we're looking for, and how the angles and sides relate to that. We're given:
The angle of elevation, 49°The distance to the base, 400 ftAnd we're looking for:
The height of the hill, which I'll call h.How do our sides relate to the angle? Well, the 400 ft side is adjacent to 49°, and the side h is opposite. From SOH-CAH-TOA, we can see that the last trig function, tangent, is equal to opposite/adjacent. Let's turn this into an equation to bring it all together:
[tex]\tan{49^\circ}=h/400[/tex]
Solving for h, we find that
[tex]h=400\tan{49^\circ}\approx400(1.15)=460[/tex]
So the heigh of the hill is approximately 460 ft.

Answer:
G = 50
H = 80
I = 50
Step-by-step explanation:
Angle in a triangle is equal to 180. This means that we will equal all the angles to 180
2x + 2x + 4x-20 = 180
8x - 20 = 180
8x = 180 + 20
8x = 200
x = 200 / 8
x = 25
G = 2 * 25 = 50
I = 2 * 25 = 50
H = 4 * 25 - 20
H = 100 - 20 = 80
Mallory is on a budget and wants to determine which cereal is a better buy. A 10-ounce box of Cereal A costs $2.70 and a 13-ounce box of Cereal B costs $3.64. The store is selling each cereal in 15 ounce boxes. Which cereal is cheaper and by how much?
Answer:
Cereal A is cheaper by $0.15
Step-by-step explanation:
Cost of a 10-ounce box of Cereal A = $2.70
So,
Cost of a 1-ounce box of Cereal A = [tex]\frac{2.70}{10}=\$0.27[/tex]
Cost of a 15-ounce box of Cereal A = [tex]0.27(15)=\$4.05[/tex]
Also,
Cost of a 13-ounce box of Cereal B = $3.64
So,
Cost of a 1-ounce box of Cereal B = [tex]\frac{3.64}{13}=\$0.28[/tex]
Cost of a 15-ounce box of Cereal B = [tex]=0.28(15)=\$4.2[/tex]
Here,
Cost of a 15-ounce box of Cereal B - Cost of a 15-ounce box of Cereal A = [tex]4.2-4.05=\$0.15[/tex]
Therefore,
Cereal A is cheaper by $0.15
