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?
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.
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.
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.

8a. Brian has $24 worth if pizzas delivered to his house for a $3 delivery fee.
He pays 7% sales tax and a 15% tip, which are both calculated on the total
price before the delivery fee. What is the total that will be added on to the
$24 pizzas? (This is the delivery fee, tax and tip)
Answer:
32.94
Step-by-step explanation:
24(.22) [Both Sales tax and tip.] = $5.28 Add to the 27. You get $32.28
Or, you could be estimating based on the delivery fee too. Which the would be this:
27(.22) = 5.94 + 27 = 32.94

Answer:
Answer 1. 3in
Answer 2. 0.875in
Answer 3. 26 miles
Answer 4. 7.67in
Step-by-step explanation:
Answer 1. We know that 2 feet in real life is going to equal 1 inch, so since the person is 6 feet, we divide that by 2 to get 3. So the action figure is going to be 3in.
Answer 2. In this case, we see that 1 foot is equal to four inches. That must mean that 1 inch is equal to a quarter foot. So we just multiply
0.25 x 3.5 = 0.875
The length is 0.875 feet
Answer 3.
We know that 1 inch = 6.5 miles, and there are 4 inches on the map, so we have to multiply 6.5 x 4 to find out how many miles there is.
Answer 4.
To find this one out, we have to divide 9 into 69. That gives us 7.67. So 69 nautical miles would be equal to 7.67 inches on the map

Consider the original parallelogram and the reduction.
What is the length of side A in the new parallelogram?
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.
Find the probability that a randomly selected point within the circle falls in the white area
Answer:
Step-by-step explanation:
The white area is the area of the circle minus the area of the triangle.
Aw=pr^2-hb/2
Aw=p4^2-6.5(6)/2
Aw=16p-19.5
The probability of selecting the white area is the white area divided by the area of the circle
P(W)=(16p-19.5)/(16p), p=3.14
P(W)=0.61
La finca de Federico tiene tiene un área de 576 m2, En ella ha sembrado naranja y café, 3/8 de la finca están sembrados de naranjas y el resto de café, ¿Cuál es el área de la finca que están sembrada por café?
Answer:
El área de la finca que está sembrada por café es 360 m².
Step-by-step explanation:
La finca de Federico tiene tiene un área de 576 m². [tex]\frac{3}{8}[/tex] de la finca están sembrados de naranjas. Entonces, el área de la finca que está sembrada por naranjas se calcula mediante:
576 m²* [tex]\frac{3}{8}[/tex] = 216 m²
Sabiendo que el resto de la finca esta sembrada de café, esta área se calcula mediante la diferencia del área total de la finca y el área sembrada por naranjas:
576 m² - 216 m²= 360 m²
El área de la finca que está sembrada por café es 360 m².

A group of 10 people is choose a chairperson and vice-chairperson. They put all 10 peoples names into a bar. The first name drawn becomes chair. The second name drawn becomes vice-chair. How many possible combinations of chair and Vice-chair are there ?
This is calculated using the Permutation formula
nPr = n!/(n - r)!
Where:
n = 10 people
r = 2 = 2 positions to be filled , Chairman and Vice chairman
Hence:
10P2 = 10!/(10 - 2)!

What's the equation?
What is an equation of the line that passes through the points (5, 5) and (5, -8)
Answer:
Write the problem as a mathematical expression. (5,5), (5,−8)
Use y=mx+b to calculate the equation of the line, where m represents the slope and b represents the y-intercept. To calculate the equation of the line, use the y=mx+b format.
Slope is equal to the change in y over the change in x , or rise over run.
m=(change in y)/(change in x)
The change in x is equal to the difference in x-coordinates (also called run), and the change in y
is equal to the difference in y-coordinates (also called rise).
m=(y2−y1) / (x2−x1)
Substitute in the values of x and y
into the equation to find the slope.
m=(−8−(5)) / (5−(5))

Step 2: Identify
(5, 5) → x₁ = 5, y₁ = 5

Step 3: Find slope m
Simply plug in the 2 coordinates into the slope formula to find slope m
Substitute in points [Slope Formula]: [tex]\displaystyle m=\frac{-8-5}{5-5}[/tex][Slope] Subtract: [tex]\displaystyle m=\frac{-13}{0}[/tex]Here we see that we have a number divided by 0.

What is the slope of the line that passes through the points (5,−4) and (7, -4) ?Write your answer in simplest form.
Answer:
Undefined
Step-by-step explanation:
[tex]\boxed{slope = \frac{y1 - y2}{x1 - x2} }[/tex]
☆ (x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.
Slope of the line
[tex] =\frac{ - 4 - ( - 4)}{7 - 5} \\ =\frac{ - 4 + 4}{2} \\ = \frac{0}{2} \\ (undefined)[/tex]
Thus, the slope of the line is undefined.
(Since 2 cannot be divided by zero)
Notice that the two coordinates have the same y- coordinate of -4. This means that the line is a vertical line. Vertical lines have undefined slopes.

Say you want to know if boys are more likely than girls to "wait for their missionary". You take a random sample of 57 males and 63 females, all of whom are in a relationship with someone who just left on a mission. You follow-up with them after the mission of their significant other returned home to determine if their relationship continue after the mission. What type of analysis is best suited for this study
Answer: 2 independent sample test of proportions
Step-by-step explanation:
The teo independent sample test of proportion is also referred to as the two proportion z-test and it simply allows the researcher to compare the two proportions in order to ascertain if they're the same or not.
In this case, the null hypothesis will be that that the proportions given in the research are the same while the alternate hypothesis will be that there is a difference between the proportions given.
The kind of analysis that would be most adequate for the given study:
Test of 2 Independent Proportions.
Independent Proportions
The test of two independent proportions is characterized as the method of study in which samples are opted randomly and allowed to remain independent.
In such a study, a minimum of 5 failures and successes are considered to reach a conclusion.
In the given situation, the samples of males and females are random and permitted to stay free("continue after the mission") and evaluated after a time to take the deduction.
