If 2/5 cup of coconut shavings covers 1/4 of a cake, then how much coconut shavings are needed for one cake? A. 3/5 cup B. 5/8 c

DanielleElmas [232]

The right answer is Option C.

Step-by-step explanation:

Given,

2/5 cup of coconut shavings covers 1/4 of a cake,

$\frac{2}{5}\ coconut\ shavings=\frac{1}{4}\ of\ cake$

For one whole cake, we will multiply both sides with 4;

$4*\frac{2}{5}=\frac{1}{4}*4\\\frac{8}{5} = 1\ cake$

Writing in simplified fraction form;

$1\ cake = 1\frac{3}{5}\ cups$

The right answer is Option C.

The area of a rectangle mirror is 11 11/16 Square feet. The width of the mirror is 2 3/4 feet. If there is a 5 foot tall space o

Oksanka [162]

We need to find the height of the mirror to solve this problem. We know the area and width, so using the formula $A=l*w$ , we have $l=\frac{A}{w}$ . Then:
$l=\frac{11\frac{11}{16}}{2\frac{3}{4}}=\frac{187}{16}*\frac{4}{11}=\frac{17}{4}$

Since $\frac{17}{4}$ is less than 5, the mirror will fit.

please answer asap! A couple plans to have 5 children. The gender of each child is equally likely. Design a simulation involving

dimulka [17.4K]

Step-by-step explanation:

The gender of a child which is either a boy or a girl is determined by the XX-chromosomes, or XY-chromosomes.

Since the couple plan to have 5 children, the chance of a child being a boy is equal to the chance of it being a girl - the chances are 50/50.

What we do to achieve our aim is to run a simulation that would add an X or Y to an X for all 5 children.

Doing this 125 times, we obtain the number of trials we desire.

For each trial, we get for each child, C:

C1: X + (X or Y)

C2: X + (X or Y)

C3: X + (X or Y)

C4: X + (X or Y)

C5: X + (X or Y)

Since the chance of having an X is equal to the chance of having a Y, they equal probability, which is 0.5 for each.

Solve for N. <br> 2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]

jonny [76]

Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

Step-by-step explanation:

We need to solve the equation $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ and find value of n.

Solving:

$2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$

Multiplying the terms inside the bracket

$2[7-6+6n]+3n=-20+4[6n+6-3n]$

Simplifying:

$2[1+6n]+3n=-20+4[6n-3n+6]$

$2[1+6n]+3n=-20+4[3n+6]$

$2+12n+3n=-20+12n+24$

$2+15n=12n+4$

Adding -12n and -2 on both sides

$15n-12n=4-2$

$3n=2$

$n=\frac{2}{3}$

So, Solving the expression $2[7-6(1-n)]+3n=-20+4[6(n+1)-3n]$ we get $n=\frac{2}{3}$

The ratio of the number of Victor’s tools to the number of Ilya tools is 5:2. Victor has 42 more tools than Ilya. How many tools

AnnyKZ [126]

Answer: Victor should give 28 tools to Ilya.

Step-by-step explanation:

Since we have given that

Ratio of the number of Victor's tools to the number of IIya's tools = 5:2

Let the number of Victor's tools be 5x

Let the number of Ilya's tools be 2x

According to question, Victo has 42 more tools than Ilya.

So, our equation becomes,

$5x-2x=42\\\\3x=42\\\\x=\dfrac{42}{3}=14$

So, number of tools Victor has 5x=5×14=70

Number of tools Ilya has 2x = 2× 14 =28

Let the number of tools that Victor should give to Ilya be 'y' so that the ratio of the number of victor's tools to the number of Ilya's tools is 3:4.

According to question, it becomes,

$\dfrac{70-y}{28+y}=\dfrac{3}{4}\\\\4(70-y)=3(28+y)\\\\280-4y=84+3y\\\\280-84=3y+4y\\\\196=7y\\\\y=28$

Hence, Victor should give 28 tools to Ilya.
