i need help with this question

Answers

Answer 1

Answer:

1) 9/20

2) 5/11

Step-by-step explanation:

For the first question: We read the number "0.45" as "45 hundredths," and we write it as the fraction 45/100. Of course, since 45 and 100 share the common factor 5, we can reduce this fraction by dividing the numerator and denominator by 5 to get the reduced form 9/20.

For our second problem, we need to perform a bit of "mathematical surgery" to find the appropriate fraction for x = 0.454545... First, the dots tell us that this fraction is repeating - those 45s will keep going on and on forever. When we multiply x by 100, then, we move the decimal two places to the right, but the repeating part still remains, giving us

[tex]100x=45.454545\dots[/tex]

From here, we can "surgically remove" the repeating bit using our original value of x:

[tex]100x-x=45.454545\dots-0.454545\dots\\99x=45[/tex]

And from here, we just have to divide both sides of the equation by 99 to solve for x:

[tex]99x=45\\x=45/99\\x=5/11[/tex]

What is the quotient of 2 ÷ 2/3?

Answers

Answer:

The answer is 3! I believe.

Step-by-step explanation:

Hello! Step by step divide 2 by 2/3 which is 2 so

1
.3=
2.3

1*2
=6

2
= 2*3

2*1
=3

Dividing the two fractions is like multiplying the first fraction by value or reciprocal value of first fraction value of SECOND fraction. So find the reciprocal like reversing the numerator and denominator reciprocal of 2/3 is 3

Of the second fraction then multiply the two numerators. Again multiply the two decnominators so the next following step intermediate step canceling by a comma factor 2 gives 3.... in words- two divided by two thirds=three

120 children go on a holiday. The ratio of the number of girls to the number of boys is 3:5. On Sunday, all the children either go sailing or go climbing. 16/25 of the boys go climbing. Twice as many girls go sailing as go climbing. Work out how many children go sailing on sunday.

Answers

Answer:

32/50

Step-by-step explanation:

hope this helps if not sorry :)

66 children go sailing on sunday.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

The number of kids go on Holiday =120

The ratio of the number of girls to the number of boys is 3/5.

Number of girls = (3/5)×120 = 72 girls.

Then there are 48 boys

120-72=48

16/25 of the boys go climbing

16/25×48=30

Boys sailing, 48-30 = 18

Twice as many girls go sailing as go climbing

Then 2x+x=72

3x=72

x=24

Therefore 48 girls are sailing and 24 are climbing

Total kids sailing 48+18=66

Hence 66 kids go sailing on sunday.

Which statement best describes the area of the triangle shown below?

A coordinate grid is shown with a triangle. The base is 4 units, and the height is 4 units (Image is also down below).

A. It is one-half the area of a rectangle of length 4 units and width 2 units.

B. It is twice the area of a rectangle of length 4 units and width 2 units.

C. It is one-half the area of a square of side length 4 units.

D. It is twice the area of a square of side length 4 units.

Answers

The answer is C. This is because the area of a triangle is height • (base divided by 2), which means the triangle has an area of 8 and the square in answer 3 has an area of 16. 8 is half of 16.

The statement that best describes the area of the triangle shown below is; Choice C; It is one-half the area of a rectangle of length 4 units and width 2 units.

Discussion;

From the grid representation in the question.

The area of the triangle are can be evaluated as;

Area(triangle) = 1/2 × 4 × 2

By observation, we can conclude that the area of the triangle is one-half the area of a rectangle of length 4 units and width 2 units.

Answer:

∞∞∞∞∞∞║°║Hello Person║°║∞∞∞∞∞∞

Your answer should be:

The total cost of Samuel's order is $29.52.

How to solve this?

Let's start off by multiplying 4 and 9.24 together. 9.24 * 4 is 36.96. Samuel gets a 25% discount, so he gets 25% off of the original combined price, but he still has to pay the remaining 75%. To find the new price, all we have to do is multiply the original price of $36.96 by 75% (0.75). When that is done, you should get 27.72. Now, there is a sales tax rate of 6.5%. 6.5% in decimal form is 0.065. Let's add 1 to that in order to get 1.065. Multiply that number by 27.72 to get the new price. 27.72 * 1.065 is 29.5218 or 29.52 when rounded to the nearest cent.
