A school ordered 3 large boxes of board markers. After giving 15 markers to each of 3 teachers, there were 90 markers left. How many markers were originally in the box?

Answers

Answer 1
Answer: 45 markers in each box.

Step-by-step explanation:
Initially, the school had 3 boxes of board markers, and each box had X board markers, where X is the number we want to find.
Then the initial number of board markers is 3*X.
We know that after giving 15 markers to 3 teachers, we have other 90 markers left. This can be written as:
total markers = markers for the teachers + markers left
3*X = 15*3 + 90 = 45 + 90 = 135
now, we divide both sides by 3.
X = 135/3 = 45
From this, we know that in each box we have 45 markers

2.35 = 235 cents

235/5 = 47 nickels

47 - 33 = 14

14 X 10 = 140

235 - 140 = 95

95/5 = 19

14 + 19 = 33

The equation x + 8 = 12 represents the number of balloons Dylan needs to decorate a place for a party. Which number line shows how many more balloons Dylan needs?

Answers

Answer:

4 balloons

Step-by-step explanation:

According to the problem, the data given are as follows,

Equation given = x + 8 = 12

Here X is showing the number of balloons which Dylan more needs to decorate.

So, by solving the equation, we get

X + 8 = 12

( by taking 8 to RHS )

X = 12 - 8

X = 4

Hence, Dylan need 4 more balloons to decorate for a party.

Give triangle ABC is a right triangle, and angle A is the right angle. If sin(B)=3/5, find the cos(B).

Answers

Answer:

Cos B = 4/5

Step-by-step explanation:

From the question given above, the following data were obtained:

Sine B = 3/5

Cos B =?

Recall:

Sine B = Opposite / Hypothenus

Sine B = 3/5

Therefore,

Opposite = 3

Hypothenus = 5

Next, we shall determine the Adjacent. This can be obtained as follow:

Opposite = 3

Hypothenus = 5

Adjacent =?

Hypo² = Adj² + Opp²

5² = Adj² + 3²

25 = Adj² + 9

Collect like terms

Adj² = 25 – 9

Adj² = 16

Take the square root of both side

Adj = √16

Adjacent = 4

Finally, we shall determine Cos B. This can be obtained as follow:

Hypothenus = 5

Adjacent = 4

Cos B =?

Cos B = Adjacent / Hypothenus

Cos B = 4/5

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

Answers

Answer:

523.3 cubic inches

Step-by-step explanation:

A basketball has a diameter of 10 in. Using = 3.14, what is the approximate volume of the basketball in cubic inches?

The shape of a basketball is spherical.

Hence:

The volume of a basketball = 4/3 × π × r³

From the question,

π = 3.14

r = radius = Diameter/2

r = 10 in/2 = 5 in

Hence:

The volume of the basketball

= 4/3 × 3.14 × 5³

= 1570 ÷ 3

= 523.33333333 cubic inches

Therefore, the approximate volume of the basketball = 523.3 cubic inches

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

The probability of being dealt three of a kind in a five-card poker hand is 0.02 or 1/50.

Answer the Following Question with Explanation

Answers

Answer:

The answer's D.

Step-by-step explanation:

If 40 questions were put in and only 50% of them were used then only 20 questions were used. If you need 40 more questions and 80% of the qustions were used, then she wrote 50 questions.

Answer:  D) 50

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

Explanation:

There are 60 questions total.

Amita made 40 questions, but only 50% were considered "good" to be used. So that means 0.50*40 = 20 questions were used.

This means 60-20 = 40 questions remain, and this must be the amount of "good" questions that Meena provided.

We're told that 80% of Meena's questions were considered "good". Let x be the total number of questions she provided.

80% of x = (number of "good" questions Meena offered)

0.80x = 40

x = 40/0.80

x = 50

Therefore, Meena wrote up 50 questions.

find the vertex y= 4x*2 -16x+10

Answers

Answer:

I hope it helps U

Step-by-step explanation:

As given quadratic equation is ,

y= 4x*2 -16x+10

As general quadratic equation is,

y=ax^2+bx+c   , we get  a=4 , b=-16 , c=10

as a=4 and +ive so the parabola is up-down facing

vertex formula is    X(vertex)= -b/2a    putt values in this formula we will get x -coordinate of vertex,

X(vertex)= -(-16)/2*4

X(vertex)= 2

Now to find the Y- Co-ordinate just plug in the value of X in the given equation, hence

Y(vertex)=4(2)^2-16*2+10

Y(vertex)=-6

hence the vertex of given equation is (2,-6)
