Answer:
13a) $3.40
13b) 0.85X
13c) $25.88
Step-by-step explanation:
13a) When there is a 15% discount, we can say that we are only paying 85% of the original price because out of 100%, 15% is taken away. 85% in decimals is 85/100 = 0.85.
$4 x 0.85 is the discounted price, which is $3.40
13b) In 13a, the price was 4. Now, the price is X. Hence we plug in (substitute) X in for 4, giving us X x 0.85, which we can write as 0.85X
13c) 85% of the cake is $22. To find 100% of the price, we can find 1% of the original price and then multiply that by 100, which gives us 100% of the price.
We know 85% of the original price. Therefore, dividng the price by 85 will give us 1% of the price. 1% = $22/85
Finally, to calculate 100%, we multiply by 100.
22/88 x 100 = 440/17 which is 25.882 in decimals, which we round to 2 decimal places (because it is currency) = $25.88

= 96 ft³
Answer:
180 ft³
Step-by-step explanation:
Total volume = base rectangular prism + top triangular prism
v = 6 * 8 * 2 + 1/2 (6 * 8 * (5.5 - 2))
v = 96 + 84 = 180

A van travelled at an average speed of 65 km/hr from town a. 35 minutes later, a car started from town A and drove along the same route as the van. if the car caught up with the van after travelling a distance of 130 km, find the average speed of the car in km/hr
The average speed of the car for the given distance is 91.97 km/hr.
What is speed and velocity?While both speed and velocity are indicators of how quickly an object is travelling, they serve different purposes. The distance travelled in a given amount of time, independent of direction, is referred to as speed, which is the magnitude of the velocity vector. In contrast, velocity is a vector quantity that accounts for both speed and direction. It is measured in units of distance per unit of time in a particular direction and is defined as the rate of change of position of an item with regard to a frame of reference.
Given that, a car started 35 minutes later that is it started after:
35 minutes = 35/60 = 0.5833 hours
Now the distance is given as:
distance = speed x time
Now, for speed = 65 km/hr:
distance = 65t
For the car the time is (t - 0.5833) thus:
distance = speed x time
130 = speed x (t - 0.5833)
Now for speed we have:
30 = s x (t - 0.5833)
130 = st - 0.5833s
130 + 0.5833s = st
130/s + 0.5833 = t
Now, substituting the value of t in the equation of the van we have:
distance = 65t
distance = 65(130/s + 0.5833)
130/s + 0.5833 = distance/65
130/s + 0.5833 = distance/65
130/s + 0.5833 = 130/65
130/s + 0.5833 = 2
s = 91.97km/hr
Hence, the average speed of the car for the given distance is 91.97 km/hr.

A map is placed on a coordinate grid. on the map, city 1 is located at (35,78) and city 2 is located at the point (47,122). If each unit is equivalent to 1 mile, how far apart are the cities?
A. (82,100)
B. (41,100)
C. (6,22)
D. (12,44)
Answer:
D
Step-by-step explanation:
Firstly, the question is phrased very very badly as the four answers provided are coordinate points rather than how far apart the cities are in units.
To calculate the distance between two points, we have to use Pythagoras' Theorem as it's just pretty much a right-angle triangle. Please look at the (terribly drawn) image provided.
Keep in mind that these points are only roughly placed on the map.
But firstly, to use Pythagoras' Theorem (a^2 + b^2 = c^2), we must find the length of the two sides.
To find the length of the horizontal line (which from now on I'll refer to as 'a'), we must subtract the smaller x value from the larger one.
47 - 35 = 12
To find the length of the vertical line (which from now on I'll refer to as 'b'), we must subtract the smaller y value from the larger one.
122 - 78 = 44
I assume that the answer you should pick is D. (12, 44)
However, that doesn't exactly answer the question... it's worded a little weirdly.
To solve the rest of the equation, do the following:
Now that we know that the length of a = 12 and the length of b = 44, we can use Pythagoras' Theorem.
a^2 + b^2 = c^2
12^2 + 44^2 = c^2
144 + 1936 = c^2
2080 = c^2
c = [tex]\sqrt{2080}[/tex]
c = 45.61
The answer is 45.61 units.

Answer:
1. sin and cos 2. complementary 3. sinA = cosB 4. 80° 5. 17
Step-by-step explanation:
1. cofunctions: having the same value at complementary angles
sin θ = cos (90 - θ), or cos θ = sin(90 - θ)
2. complementary: two angles sum to 90°, supplementary: two angles sum to 180°
one of the angle in a right triangle must be a right angle = 90°
180°(sum of angles of a triangle) - 90° = 90°(the sum of the other two angles) => which is complementary
3. sinA = cosB
4. cos θ = sin(90 - θ)
=> cos 10° = sin(90 - 10°)
=> cos 10° = sin(80°)
5. sin θ = cos (90 - θ)
=> sin 73° = cos (90 - 73°)
=> sin 73° = cos (17°)

Answer:
8.25 kg
Step-by-step explanation:
Given that,
Weight of Apples = 3 3/4 kg
Weight of guava = 4 1/2 kg
Total weight of fruits = weight of apples + weight of guava
[tex]=3\dfrac{3}{4}+4\dfrac{1}{2}\\\\=\dfrac{15}{4}+\dfrac{9}{2}\\\\=8.25\ kg[/tex]
