k = 48Step-by-step explanation:
Given expression:
33 is 15 less than kConvert this into equation and solve for k:
33 = k - 15k = 33 + 15k = 48So the value of k is 48

First we need to convert this verbal phrase into an equation.
\(\textsl{33 is less than k. } === > \textsl{33=k-15}\).
NOW we need to add 15 to both sides.
\(\textsl{33+15=k}\)
\(\textsl{48=k}\)

What is the perimeter of the shape below? Use 3.14 for pi. Answer with numbers only, no units.
DO NOT ROUND THE ANSWER
Step-by-step explanation:
The circumference of a WHOLE circle = pi * d
you have 1/2 of this and d = 10 ft
so 1/2 pi * 10 PLUS the two straight sides + 8+6
1/2 pi * 10 + 8 + 6
5 pi + 8 + 6
5 * 3.14 + 14 = 29.7 ft

A car left Town A at 9:30 a.m. and reached Town B at 11:30 a.m. Its average speed was 60 km/h. Find the distance between Town A and Town B.
Answer:
120 km
Step-by-step explanation:
its average speed was 60 km an hour and it took 2 hours from town a to town b so 60km + 60km = 120
\({\large {\orange{\underline {\underline {\mathcal {♡AnSwER♡⤵}}}}}}\)
Left Town A at 9:30 am
Reached town B at 11:30 a.m
Therefore, Time taken by the car is =( 11:30 - 9:30) hrs =2 hrs
The speed of the car =60 km/h
So, the distance between Town A and B is = (Speed × Time) =( 60 × 2 )km =120 km.
The distance between Town A and B is 120 km. (Ans)

Step-by-step explanation:
If f(x) = 2x²+2 and g(x)=x2-1, find (f- g)(x).
The function g (x) is called an inner function and the function f (x) is called an outer function. Hence, we can also read f [g (x)] as “the function g is the inner function of the outer function f”.
Given that,
f(x) = 2x²+2 and
g(x)=x2-1
So find the (f- g)(x).
(f- g)(x) means,
Multiply x into f and g functions
Then, (f- g)(x) = f(x)-g(x)
Replace with f(x) and g(x) values in this equation
So,
(f- g)(x)= f(x)-g(x)
= (2x²+2) - (x2-1)
Distribute the subtraction to all three of the last terms.
= 2x²+2-2x+1
= 2x²-2x+2+1
Combine like terms
(f- g)(x) = 2x²-2x+3
Therefore,
f(x) = 2x²+2 and
g(x)=x2-1,
So,
(f- g)(x) = 2x²-2x+3.

In 1968, vehicle emission standards allowed
6.3 hydrocarbons released per mile driven. By 1980, the
standards allowed only 0.41 hydrocarbons per mile driven.
What was the rate of change from 1968 to 1980?
Answer:
Step-by-step explanation:
In 1968, vehicle emission standards allowed 6.3 hydrocarbons released per mile driven and by 1980, the
standards allowed only 0.41 hydrocarbons per mile driven. This means that the change in the amount of hydrocarbons released per mile driven as allowed by the vehicle emission standards between 1968 and 1980 is
6.3 - 0.41 = 5.89
Therefore, the percentage rate of change in the amount of hydrocarbons released per mile driven as allowed by the vehicle emission standards between 1968 and 1980 would be
5.89/6.3 × 100 = 93.49%
A ship leaves port on a bearing of 36.0° and travels 12.1 mi. The ship then turns due east and travels 6.1 mi. How far is the ship from port, and what is its bearing
The bearing angle exists 53.49°.
How to estimate the bearing angle of a ship?A bearing of 36° corresponds to the corresponding angle of
θ = 90 -36 = 54°
The (x, y) values for the position of the ship after achieving its first heading exist:
\(x_1\) = 12.1 Cos 54° = 7.11 m
\(y_1\) = 12.1 Sin 54° = 9.78 m
Our second displacement exists a simple 4.6 mi due east, that exists, the positive x-direction. The components exist therefore
\(x_2\) = 6.1 mi
\(y_2\) = 0 mi
To find the total displacement from the port, we'll add these two vectors' components and use the distance formula:
Δx \(= x_1+x_2\)
= 7.11 mi + 6.1 mi = 13.21 mi
Δy \(=y_1+y_2\)
= 9.78 mi + 0 mi = 9.78 mi
\($r=\sqrt{(x_{total})^2+(y_{total})^2}\)
\(=\sqrt{(13.21mi)^2+(9.78mi)^2}\)
= 16.43 mi
The direction of the displacement vector exists given by
tan θ = Δy/Δx
θ = arc tan (Δy/Δx)
= arc tan (9.78/13.21)
= 36.51°
The question requested for the bearing angle, which exists just this angle subtracted from 90°:
90° - 36.51° = 53.49°.
Therefore, the bearing angle exists 53.49°.

the length of a rectangular swimming pool is 50 yards and the width of the pool is 20 yards. what is the approximate length of the diagonal of this pool?
The length of a rectangular swimming pool = 50 yards
The width of a rectangular swimming pool = 20 yards
We can use the Pythagoras theorem to find the length of the diagonal.
\(\begin{gathered} c^2=a^2+b^2 \\ c^2=50^2+20^2 \\ c^2=2500+400 \\ c^2=2900 \\ c=\sqrt[]{2900} \\ c=53.85\: \text{yards} \end{gathered}\)Therefore, the approximate length of the diagonal of this pool is 53.85 yards.
Option (A) is correct.
Use the distributive property to remove the parentheses. -3(4v-2y-6)
-12v+6y+18
you multiply everything by -3, so -3×4v=-12v
-3×(-2y)=6y, since negative × negative=positive
-3×(-6)=18

In a recent survey,77 % of the community favored building a health center in their neighborhood. If 14 citizens are chosen, find the probability that exactly 8 of them favor the building of the health center. Round to the nearest three decimal places.
The probability of that exactly 8 of them favor the building of the health center is 0. 399
How to determine the probabilityFrom the information given, we have that 70% of the community favors the building of the health center
Number of citizens chosen = 14
P(8) = \(\frac{8}{14}\) × \(\frac{70}{100}\)
P(8) = \(0. 57\) × \(0. 7\)
P(8) = \(0. 399\)
Thus, the probability of that exactly 8 of them favor the building of the health center is 0. 399

Carissa the chessplayer is a very, very slow walker. In fact, she walks at 100 meters per hour when walking uphill, 180 meters per hour when walking across flat ground, and 250 meters per hour when walking downhill. One day, Carissa walks across Boston from a café to a boba shop, and then takes the same route in reverse to return to the café. If there are equal parts of uphill, flat ground, and downhill, then what was Carissa's average speed during the entire round trip?
According to the statement, the Ship must move at an average pace of 150 meters per hour.
Is Downhill unfavorable?The variable under examination is lessened when the gradient is "downhill" (negative). When used as a gauge of how well things are doing, "downhill" denotes a downward trend. Yet, if this indicates trouble or some other unpleasant quality, the situation is improving.
The chess player Carissa walks very, very slowly. She actually moves at speeds of 100 meters per hr upward, 150 meters per hr on flat terrain, and 200 meters every hour on downhill terrain.
Here,
Carissa traverses Boston on foot from a coffeehouse to a boba store before returning over the same path.
Total distance walked = 2 [200 + 100 + 150] = 900 meter
Total time = 2 [1 + 1 + 1] = 6 hour
Average speed is calculated as distance divided by time (900 / 6 = 150 m/s),
As a result, the needed Carissa average speed is 150 meters per hr.

Step-by-step explanation:
Seperate it into two pieces;
Piece 1, base of 2, height of 9
Piece 2, base of 8, height of 5.
Area of Piece 1:
A = bh
A = 2 (9) = 18
Area of Piece 2:
A = bh
A = 8 (5) = 40
Add the areas of both pieces:
18 + 40 = 58 m2
What is the area of the shaded region?
Answer:
80 mm²
Step-by-step explanation:
Even for slanted triangles, the area is base x half height! The base is 10 mm, half the height is 8 mm, so the area is 8x10=80 mm.
a water snake in a well is 30 M below the ground level its lights 20 m upward and then slips down 10 M how far it is from the ground level
\( - 30 - + 20 - - 10\)
If the water snake is initially 30 meters below the ground level and then climbs 20 meters upward, it will be 30 - 20 = 10 meters below the ground level. However, if it then slips down 10 meters, it will be 10 + 10 = 20 meters below the ground level.
