What is the angle of depression from the start of a 6-foot high access ramp that ends at a point 40 feet away along the ground? Nearest tenth of a degree.
Given:
Height of access ramp = 6 foot
Ramp ends at a point 40 feet away along the ground.
To find:
The angle of depression in nearest tenth of a degree.
Solution:
Using the given information, draw a figure as shown below.
In a right angle triangle,
[tex]\tan \theta = \dfrac{\text{Perpendicular}}{\text{Base}}[/tex]
In triangle ABC,
[tex]\tan \theta=\dfrac{AB}{BC}[/tex]
[tex]\tan \theta=\dfrac{6}{40}[/tex]
[tex]\tan \theta=0.15[/tex]
Taking tan inverse on both sides.
[tex]\theta=\tan^{-1}(0.15)[/tex]
[tex]\theta=8.5307656[/tex]
[tex]\theta \approx 8.5[/tex]
Therefore, the angle of depression is 8.5 degrees.
2. Doug can row 3 1/2 miles in 1/4 hour. What
is his average speed in miles per hour?
SHOW WORK!
Answer:
14 miles
Step-by-step explanation:
He can row 3.5 miles in .25 hours.
If there are 60 mins in an hour. Take the .25 hour and times by 4 to get a whole hour.
Since 3.5 miles is for .25 hr, take the 3.5 times by 4 to get what he rows in a whole hour.
3.5*4= 14 miles.
a company sells kites it sells basic and designer kites 2 basic kites and 2 designer kites are 400g 4 basic kites and 1 designer are 440g work out the weight of a basic and a designer kit
Answer:
380g
Step-by-step explanation:
hope this answer will help u
The weight of basic kit is 73.33 g and weight of Designer kit 146.68 g.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
let the weight of basic kit be x and weight of designer kit be y.
The weight of 2 basic kites and 2 designer kites are 400g.
and, the weight of 4 basic kites and 1 designer kites are 440g.
So, the system of equation is
2x + 2y = 400.............(1)
4x + y = 440
y = 440 - 4x.............(2)
Solving equation (1) and (2), we get
2x + 2(440 - 4x) = 400
2x + 880 - 8x = 400
-6x = -440
x = 73.33
and, y= 440 - 4(73.33)
y = 146.68

DE is parallel to AC. Find the measure of angle x and z. Explain how you know.
Answer:
x= 67 degrees and z= 54 degrees
Step-by-step explanation:
Using alternative interior angle, you can see that x is equal to 67 degrees
-In a triangle, there is 180 degrees. Since there are 59 degrees and 67 degrees in the triangle, you will just need to solve for z.
-In order to solve for z, you subtract 180-59-67= 54

Number 35, I need that answered DUE IN 1 HOUR PLZ ANSWER ASAP
Answer:
18.5
Step-by-step explanation:
It says
IJ is the midsegment of the triangle. So it divides both adjacent sides in half/at modpoint.
so HF is 10 cm .. half of that is 5 cm
GH is 13 cm.. Half of that is 6.5 cm
now we have IJ = 7 cm given
add all those.. you get 18.5 cm
Answer:
18.5
Step-by-step explanation:
35.
Segment IJ is a midsegment of triangle FGH, so
2HI = 2FI = FH
2HJ = 2JG = GH
FG = 2IJ
Perimeter of triangle IJH = IJ + JH + HI
IJ + JH + HI = 7 + 6.5 + 5 = 18.5

Layla has a coin that has a 60%, percent chance of showing heads each time it is flipped. She is going to flip the coin 5 times. Let X represent the number of heads she gets. What is the probability that she gets more than 3 heads?
Answer:
0.33696
Step-by-step explanation:
Given that:
Probability of showing up head (p) = 0.6
Number of flips = number of trials = 5
Probability of getting more than 3 heads
P(x = x) = nCx * p^x * (1 - p)^(n-x)
P(x> 3) = p(4) + p(5)
P(x = 4) = 5C4 * 0.6^4 * 0.4^1 = 0.2592
P(x = 5) = 5C5 * 0.6^5 * 0.4^0 = 0.07776
Hence,
0.2592 + 0.07776
= 0.33696
Following are the calculation to the probability:
The probability to see the head [tex](p)= 60\%= 0.60[/tex]
Amount of flips = amount of tries = 5
Chances of getting and over three heads:
[tex]\to P(x = x) = ^n C_x \times p^x \times (1 - p)^{(n-x)}\\\\\to P(x> 3) = p(4) + p(5)\\\\\to P(x = 4) = ^5 C_4 \times 0.6^4 \times 0.4^1 = 0.2592\\\\\to P(x = 5) = ^5 C_5 \times 0.6^5 \times 0.4^0 = 0.07776\\[/tex]
Hence,
[tex]\to 0.2592 + 0.07776= 0.33696 \approx 0.34\\\\[/tex]
Therefore, the final answer is "0.34"

10 1/2 cups of flour are needed to make 3 loaves of bread. How many cups are needed for 12?
Answer:
42 cups of flour
Step-by-step explanation:
12 is 4 times more than 3 (3 × 4 = 12), so we know that we need 4 times 10 1/2 (equal to 10.5) cups of flour.
All we need to do for this is do 10.5 × 4 = x and solve for x.
10.5 × 4 = 42 cups of flour
