Answer:
x = 4, z = 77
Step-by-step explanation:
From the figure attached,
(15x + 43)° = (8x + 71)° [Vertically opposite angles]
15x - 8x = 71 - 43
7x = 28
x = 4
Therefore, (15x + 43)° = (15×4 + 43)°
= 103°
Now, z° + (15x + 43)° = 180° [Linear pair of angles]
z° + 103° = 180°
z° = 180 - 103
z = 77
Therefore, x = 4 and z = 77 is the answer.
The height of a room is 10 feet. You are installing floor-to-ceiling shelving, and each shelf is 8 inches tall. Write and solve an inequality for the number of shelves you could possibly build.
10 feet = 120 inches
120 divided by 8 = 15
you can have 15 shelves in the room

A woman sold a typewriter for Rs 13718 in the system of compound depriciation at the rate of 5 percent .If she had purchased it 3 years before how much did she pay for it by that time?
Answer:
Rs 16000
Step-by-step explanation:
Given that :
Price at which typewriter was sold = Rs 13718
Compound Depreciation rate = 5%
Time = 3 years
Amount paid for typewriter 3 years ago
Using the relation :
Final amount = Initial amount(1 - r/n)^nt
n = number of compounding times per period
Rate = r = 5% = 0.05
t = time
A = Final amount = 13718
Initial amount = original purchase price (p)
Therefore ;
13718 = p(1 - 0.05)^3
13718 = p(0.95)^3
13718 = p * 0.857375
13718 = 0.857375p
p = 13718 / 0.857375
P = Rs 16000
Amount paid at the time of purchase = 16000

Find the measure of the indicated angle. Round to the nearest tenth of a
degree.
Step-by-step explanation:
Using trignometry, we have cosθ = Adjacent / Hypotenuse = 3/5.
Hence θ = cos-1(3/5) = 53.1° (A).
You notice a hot air balloon descending. The elevation h (in feet) of the balloon is modeled by the function h(x)=−6x+330, where x is the time (in seconds) since you first noticed the hot air balloon. ANSWER FASTTTTT!!!
Answer:
55 secsStep-by-step explanation:
Given the elevation h (in feet) of the balloon modeled by the function h(x)=−6x+330, we can calculate the time it takes the balloon to reach the ground. The hot air balloon hits the ground at h(x) = 0.
Substitute h(x) = 0 into the modeled expression and find x as shown;
h(x)=−6x+330
0 = −6x+330
6x = 330
Divide both sides by 6
6x/6 = 330/6
x = 55 seconds
Hence the hot air balloon hits the ground after 55 seconds
If the temperature outside increases by 3 1/2 degrees every 1 1/2 hours, by how much will the temperature increase after 4 hours?
please answer in fractions.
Part 1:
What is the rate per hour of the temperature increase?
Part 2:
How much will the temperature increase after 4 hours?
Answer:
Part 1: 7/3 degrees/hour
Part 2: 28/3 degrees
Step-by-step explanation:
Part 1:
3 1/2 degrees per 1 1/2 hours =
= (3 1/2)/(1 1/2)
= (7/2) / (3/2)
= 7/2 * 2/3
= 7/3 degrees/hour
The rate is 7/3 degree per hour
Part 2:
In 4 hours, the temperature goes up 4 times what it goes up in 1 hour.
4 hours * 7/3 degree/hour = 28/3 degrees

Question 3 (2 points)
Use the figure below to answer the following questions. Find the measure of each angle.
Answer:
∠ 1 = 70°, ∠ 2 = 140
Step-by-step explanation:
110° and the adjacent angle inside the triangle are supplementary, then
angle = 180° - 110° = 70°
Since 2 sides of the triangle are congruent, then the triangle is isosceles
Thus the 2 base angles are congruent, then
∠ 1 = 70°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 2 is an exterior angle of the triangle, thus
∠ 2 = 70° + 70° = 140°

Answer:
5.5 cm/minute
Step-by-step explanation:
Given that,
The yellow turtle country covered 33 cm in six minutes.
To find unit rate, divide distance covered by the time.
Here, distance = 33 cm
Time, t = 6 minutes
[tex]R=\dfrac{33\ \text{cm}}{6\ \text{minutes}}\\\\=5.5\ \text{cm/minutes}[/tex]
Hence, the unit rate is 5.5 cm/minute. It means, Courtney covered 5.5 cm in one minute.

A color printer prints 21 pages in 9 minutes. How many pages does it print per minute? Round your answer to the nearest hundredth.
? = pages per minute
Answer:
2.33 = x
Step-by-step explanation:
pages minutes
21 9
x 1
Cross multiply.
21×1 = 9×x
21 9x
9 9
9 cancels 9 leaving x. and 21 divided by 9 equals 2.33 pages. NB. both sides are divided by 9 because we want x by itself and what you do to one side, you have to do to the other.
Rosalina is driving to visit her family which live 150 km away her average speed is 60 km/h the cars tank is 20 L of fuel at the beginning of the drive and its fuel efficiency is 6 km perL fuel cost $.60 per liter how long can Roselene drive before she runs out of fuel
Answer:
With the amount of fuel she has, she can drive 120 km which will take 2 hours.
Step-by-step explanation:
You need to figure out which information is necessary for this problem and which is not.
The fuel tank has 20 L.
The car drives 6 km per L.
20 L * 6 km/L = 120 km
She can drive 120 km with the amount of fuel she has.
She is driving at 60 km/h.
speed = distance/time
time * speed = distance
time = distance/speed
time = (120 km)/(60 km/h) = 2 hours
Answer: With the amount of fuel she has, she can drive 120 km which will take 2 hours.

Step-by-step explanation:
The diagonals of rhombus ABCD intersect at E. Given that m∠CAD=20° and CE=4, find the m∠CDA.
Given :
The diagonals of rhombus ABCD intersect at E.
∠CAD = 20°.
To Find :
The angle ∠CDA.
Solution :
We know, diagonals of a rhombus bisects each other perpendicularly.
So, ∠DEA = 90°.
In triangle ΔEAD :
∠EAD + ∠AED + ∠EDA = 180°
20° + 90° + ∠EDA = 180°
∠EDA = 70°
Now, we know diagonal of rhombus also bisect the angle between two sides .
So, ∠CDA = 2∠EDA
∠CDA = 2×70°
∠CDA =140°
Therefore, ∠CDA is 140°.

. William fills 1/3 of a water bottle in 1/6 of a minute. How much time will it
take him to fill the bottle?
Answer:
1/2 minute
Step-by-step explanation:
We can use a ratio to solve
1/3 bottle 1 bottle
------------ = --------------
1/6 minute x minutes
Using cross products
1/3x = 1/6 *1
1/3 x = 1/6
Multiply each side by 3
3 * 1/3x = 3 * 1/6
x = 3/6
x = 1/2
1/2 minute
Answer:
30 seconds (1/2 minute)
Step-by-step explanation:
We are given that,
Amount of water filled in 1/6 minute = 1/3
Now, Let the time taken to fill the whole bottle with water be x
Hence,
Through the ratio method we get,
1/3:1/6 : : 1:x
Hence, we need to multiply the extremes and the means together and equalize them.
Hence,
x/3=1/6
x=(1/6)×3
x=(1/2) minute or 30 seconds
