60% of the vehicles owned by a transport company are trucks, 15% are vans and the rest are buses. If there are 10 buses, how many trucks are there?
Answers
Answer:
Hope this help, pls mark me as Brainliest!
Step-by-step explanation:
60% = 0.6
15% = 0.15
10 = 0.15
Answer:
24
Step-by-step explanation:
Let x represent total number of vehicles
Let T represent number of trucks
Let V represent number of vans
Let B represent number of buses
Convert percent's to decimals:
60% = 0.6
15% = 0.15
Set up equations:
T = 0.6x
V= 0.15x
B= (1 - 0.6 - 0.15)x
For buses, the remaining portion of the 100% of vehicles is 100% -60% -15%
Since we know there are 10 buses, set B=10
B= (1 - 0.6 - 0.15)x
10= (1 - 0.6 - 0.15)x
10= 0.25 x
Divide both sides by 0.25 so that we get:
10/0.25 = x
x= 40
We now know there are 40 vehicles present. To find the number of trucks, we take 60% of the total number of vehicles
T = 0.6x
T= 0.6 (40)
T= 24
Therefore there are 24 trucks.

C. Both answers A and B are true.
D. Both answers A and B are NOT true.
Answers
Answer:
C.Both answers A and B are true.
Step-by-step explanation:
My teacher told me that was right.
Both answer A and B are true about the Pythagorean Theorem.
Here,
We have to find about the Pythagorean Theorem and its converse.
What is Pythagorean Theorem?
Pythagorean Theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
Now,
In option A;
It states about the Pythagorean Theorem,
Pythagorean theorem is well known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
Hence, option A is true.
In the option B; converse of Pythagoras theorem states that;
If the square of a side is equal to the sum of the square of the other two sides, then triangle must be right triangle.
Hence option B is true.
Clearly, Both answer A and B are true about the Pythagorean Theorem.

Consider the original parallelogram and the reduction.
What is the length of side A in the new parallelogram?
Answers
Given:
The given figure represents the original parallelogram and the reduction.
To find:
The length of side A in the new parallelogram.
Solution:
We know that the original figure is always similar to its reduction. So, both parallelograms are similar to each other.
The corresponding sides of similar figures are proportional.
[tex]\dfrac{45}{18}=\dfrac{5}{A}[/tex]
[tex]45\times A=5\times 18[/tex]
[tex]45A=90[/tex]
Divide both sides by 45.
[tex]A=\dfrac{90}{45}[/tex]
[tex]A=2[/tex]
The length of side A in the new parallelogram is 2 cm. Therefore, the correct option is A.

A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius.
Answers
Answer:
90 degrees
Step-by-step explanation:
Complete question
A coffee is sitting on Mr. Hunt's desk cooling. It cools according to the function T=70(0.80)^x+20, where x is the time in minutes and T is the temperature in degree Celsius. WHAT IS THE INITIAL temperature of the coffee
The initial temperature occurs at x = 0
Substitute x = 0 into the expression;
T=70(0.80)^x+20
T =70(0.80)^0+20
Since any value raise to power of zero is 1, hence;
T = 70(1)+20
T = 70+20
T = 90 degree Celsius
Hence the initial temperature of the coffee is 90 degrees
The initial temperature of the coffee is 90 degrees.
The function is represented as:
[tex]\mathbf{T = 70(0.80)^x + 20}[/tex]
At the initial temperature, x = 0.
So, we have:
[tex]\mathbf{T = 70(0.80)^0 + 20}[/tex]
Expand
[tex]\mathbf{T = 70 \times 1 + 20}[/tex]
Multiply
[tex]\mathbf{T = 70 + 20}[/tex]
Add
[tex]\mathbf{T = 90}[/tex]
Hence, the initial temperature of the coffee is 90 degrees.

all you do is combined your slope and y-intercept together: Y= -2/5X , you dont need to add +0 because it gonna just still be the same as y= - 2/5x

B. Selected number is an odd number less than 20
C . Selected number is even
Answers
Answer:
Event B has the smallest probability and Even C has the greatest probability
Step-by-step explanation:
There are more odd number greater than 50 than odd numbers less than 20
So the probability of selecting an odd number greater than 50 is greater than the probability of selecting an odd numbers less than 20
There are more even numbers than odd numbers greater than 50
So the probability of selecting an even number is greater than the probability of selecting an odd number greater than 50
