Answer:

19 cars

13 buses

Step-by-step explanation:

We have a system of equations as follows

X + y = 32 -----1

3x + 27y = 408 ----2

x = car

y = bus

From equation 1

x + y = 32

x = 32 - y ---- 3

We put equation 3 into equation 2

3(32-y) + 27y = 408

96y -3y + 27y = 408

96 + 24y = 408

24y = 408 - 96

24y = 312

Divide through by 24 to get the value of y

Y = 312/24

Y = 13

We put the value of y in equation 3

x = 32 - 13

x = 19

So 19 cars would be needed for the trip and also 13 buses would also be needed

Answer:

[tex] n = \frac {p - 4m}{m} [/tex]

Step-by-step explanation:

Given the algebraic expression;

[tex] m = \frac {p}{n + 4} [/tex]

To make n the subject of formula.

Cross-multiplying, we have;

[tex] m*(n+4) = p [/tex]

[tex] mn + 4m = p[/tex]

Rearranging the equation, we have;

[tex] mn = p - 4m [/tex]

[tex] n = \frac {p - 4m}{m} [/tex]

Answer:

[tex]m = \frac{p}{(n + 4)} \\ (n + 4)m = p \\ nm + 4m = p \\ nm = p - 4m \\ n = \frac{p - 4m}{m} \\ n =( \frac{p}{m} - 4)[/tex]

Answer:

34 degrees

Step-by-step explanation:

34 degrees

the angle is 90 degrees

90-56=34

======================================================

Explanation:

Refer to the diagram below. I've added the variable y as the base angles to the isosceles triangle on the left.

Recall that the angles opposite the congruent sides are the base angles. The base angles of any isosceles triangle are the same measure.

Let's solve for y

y+y+56 = 180 .... all angles in a triangle add to 180

2y+56 = 180

2y = 180-56

2y = 124

y = 124/2

y = 62

I've also added the variable z, which is adjacent to one of the y angles.

Since y and z combine to form a straight angle, this means the two angles add to 180

y+z = 180

z = 180-y

z = 180-62

z = 118

Now focus on the isosceles triangle on the right. It has angles x, x, and z = 118.

x+x+z = 180

x+x+118 = 180

2x+118 = 180

2x = 180-118

2x = 62

x = 62/2

x = 31

Answer:

Number of ducks = 37

Number of pigs = 18

Step-by-step explanation:

Let,

x be the number of ducks

y be the number of pigs

According to given statement;

x+y=55     Eqn 1

2x+4y=146     Eqn 2 (As ducks will have 2 legs and pigs will have 4)

Multiplying Eqn 1 by 2

2(x+y=55)

2x+2y=110    Eqn 3

Subtracting Eqn 3 from Eqn 2

(2x+4y)-(2x+2y)=146-110

2x+4y-2x-2y=36

2y=36

Dividing both sides by 2

[tex]\frac{2y}{2}=\frac{36}{2}\\y=18[/tex]

Putting y=18 in Eqn 1

x+18=55

x = 55-18

x = 37

Hence,

Number of ducks = 37

Number of pigs = 18

Answer:

length= 90feet

width =72 feet

Step-by-step explanation:

perimeter=2(L+W)

324=2(L+W)

324/2=L+W

162=L+W( at a ratio of 10:8)

length=10/18 * 162=90

width=8/18*162=72

2(90+72)=324

Answer:

Step-by-step explanation:

If Yoko made 231 dollars in 11 hours, it means that she makes

231/11=21 dollars per hour

in 8 hours

8*21=168 dollars in 8 hours

Answer:

168

Step-by-step explanation:

We need to find how much money she makes in one hour. Then multiply that by 8.

231 ÷ 11 = 21

21 × 8 = 168

Answer:

Both of those terms are divisible by 5, so you could express it also as

5(3p + 2q)

The equivalent expression is [tex]5(3p+2q)[/tex].

Important information:

We need to find the equivalent expression by using the distributive property.

According to the distributive property:

[tex]a(b+c)=ab+ac[/tex]

The given expression can be written as:

[tex]=5\times 3p+5\times 2q[/tex]

[tex]=5(3p+2q)[/tex]

Therefore, the equivalent expression is [tex]5(3p+2q)[/tex].

Answer:

12 more games

Step-by-step explanation:

15 + 12 = 27

27 is 90% of 30 , so they need to win 12 more games but 27 overall out of the 30

30 = 100%

27 = x

x = 27×100%/30

x = 2700%/30

x = 90%

Answer:

World population = 7,468,935,407

Step-by-step explanation:

Given that:

Percent of people who have internet connection = 41%

Number of people who have internet connection = 3,062,263,517

Let,

x be the world population.

41% of x = 3062263517

[tex]\frac{41}{100}x=3062263517\\[/tex]

0.41x = 3062263517

Dividing both sides by 0.41

[tex]\frac{0.41x}{0.41}=\frac{3062263517}{0.41}\\x=7468935407[/tex]

Hence,

World population = 7,468,935,407

just divide 300/20 to get 15

answer is 15

Step-by-step explanation:

SPEED (in miles/hour),  TIME (in hours)

This analyst determined the relationship between the 2 measures above, using 20 trials.

The correlation coefficient between both factors was -0.276

Now, correlation coefficient is a figure that shows the strength and direction of two quantities. The quantities here are speed and time.

The minus sign in this correlation coefficient shows a negative movement of one quantity against the other. In other words, as one quantity moves up, the other goes down, and vice versa. An increase in magnitude of speed will result in a decrease in magnitude of time spent driving. Vice versa.

If you plot speed against time, the graph (that joins each point of intersection of speed and time together) will slope downwards showing the opposing movements of time and speed.

How is the correlation affected if the units for time (time only, not speed) are changed from hours to minutes?

If the units for each time measured are changed to minutes while that of speed is left in hours, the magnitude of each time measured will increase by 60.

For example, if three of the twenty trials have the following values for time -  1.5 hours,  2.3 hours,  3.6 hours

then they will be multiplied by 60, in order to change to minutes. The new values are shown below:

90 minutes,  138 minutes,  216 minutes

THIS CHANGE ON THE VARIABLE TIME ALONE, WILL CAUSE IT TO CARRY MORE MAGNITUDE WHILE THE TIME IN THE MEASUREMENT OF SPEED REMAINS THE SAME.

WHAT THIS WILL DO TO THE CORRELATION COEFFICIENT IS: to lower the value of the figure from 0.276 to a value like 0.043

The minus sign will still remain, as speed and time are still moving in opposite directions.

The value of the correlation coefficient will drop!
