At the King School, 55% of the students take a bus to school. If 220 students take a bus to school, how many students are there in total?

Answers

Answer:

400 student

55/100 * x(unknown) = 220

55x/100 =220

CROSS MULTIPLY

55X = 22000

X = 22000/55

X = 400

The total number of students at the King School is 440.

Given that, at the King School, 55% of the students take a bus to school.

What is percentage?

Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".

Let the total number of students be x

So, 55% of x =220

⇒ 55/10 ×x=220

⇒ 0.55x=220

⇒ x=220/0.55

⇒ x=440

Therefore, the total number of students at the King School is 440.

John is about to take a 75-item multiple-choice test. If he finishes an average
of 5 items every 3 minutes, how long will it take him to complete the test?
1. 15 minutes
2. 25 minutes
3. 45 minutes
4. 60 minutes

Answers

Answer:

It will take John 45 minutes (option 3 or C) to finish the test.

Step-by-step explanation:

We know that John is about to take a 75-item quiz. If he finishes 5 items every 3 minutes, then we can divide 75 by 5.

75 ÷ 5 = 15

Now, let's multiply 15 minutes by 3 minutes to get the total amount of minutes.

15 x 3 = 45 minutes

Therefore, it will take John C. 45 minutes to finish the test.

Henry rode his motorcycle from his house to a friend's house. After riding 10 miles, he realizes he has traveled 2/3 of the way. How far is Bob's house from his friend's house?
A. 20 miles
B. 15 miles
C. 12 miles
D. 25 miles​

Answers

Step-by-step explanation:

2/3 of diatance = 10 miles

3/3 of distance = 10 * (3/2) = 15 miles.

The distance between the houses is 15 miles. (B)

Let the total distance covered= x

Distance covered= 10 miles

According to the question,

2/3 of x= 10

=> 2/3 × x= 10

=> 2x/3= 10

=> 2x= 10× 3

=> 2x= 30

=> x= 30/2

=> x= 15

Bob's house is 15 miles away from Henry's house.

so first we need to substitute 3 into the expression
3^2 + 3 / 3 - 1
9 + 3 / 2
12 / 2 = 6
hope this helps! :)
Answer: 6
If x=3 we first need to find the value of all the x’s is this equation starting with x to the power of two
3•3=9
now we add 3 to nine since it is directly next to it
3+9=12
for the divisor we have x-1
(3)-1=2
so now that we have all the values we simply divide
12/2=6

Amanda is practicing her dives off the diving board. When she dives into the water, the path her body makes and where she resurfaces can be modeled by the equation 0=2−8+7 where is the number of horizontal feet she travels. Solve the equation to find the number of feet she will travel before coming back to the surface of the water.

Answers

Answer:

The number of feet she will travel back is 1 or 7 feet

Step-by-step explanation:

Here, we need to solve the quadratic equation

That will be as follows;

0 = x^2 -8x + 7

x^2-x-7x+ 7 = 0

x(x-1)-7(x-1) = 0

(x-1)(x-7) = 0

x = 1 or 7

The number of feet she will travel before coming back to the surface of the water is 1 or 7 feet

touching a window sill, and makes an angle of
62° with the ground. Find the height of the
window sill above the ground. How far is the
foot of the ladder from the foot of the wall?​

Answers

Answer:

5.74m, 3.05m

Step-by-step explanation:

The set up is a right angled triangle.

Length of the ladder is the hypotenuse = 6.5m

Angle of elevation = 62°

Required

Height of the window (opposite)

Using SOH CAH TOA trigonometry identity

Sin theta = opp/hyp

Sin62 = opp/6.5

Opp = 6.5sin62

Opp = 5.74m

Hence the height of the window is 5.74m

The distance of the ladder from the foot of the wall is the adjacent

Cos 62 = adj/6.5

adj = 6.5cos62

adj = 3.05m

Hence the distance of the ladder from the foot of the wall is 3.05m

A card is drawn from an ordinary deck of cards. What is the probability that the card is a king given that the card is red?

A. P(K|R) = 0.8
B. P(K|R) = 0.2
C. P(K|R) = 0.92
D. P(K|R) = 0.08

Answers

Answer:

d. 0.08

Step-by-step explanation:

52 cards in a deck of cards. 26 are red. there are 2 red kings. 2/26= 0.076 which rounds up to 0.08

Half the cards (26) are red

Then there are 2 red kings out of the 26.

Probability of picking a red king out of the red cards is 2/26 = 1/13 = 0.076

Round to 0.08
