Which expression is equivalent to ?

Answer:

3.78*2=7.56

7.38*4=29.52

29.52+7.56=37.08

220-37.08=182.92

Answer:

2.3 lbs.

Step-by-step explanation:

Cherry=1.56

3.86-1.56= 2.3

The answer is 12.57

But rounded to the nearest tenth is 12.6

Answer:

70%

Step-by-step explanation:

Each blue line represents 10%.  Since there are 7 blue lines, we just multiply 10% by 7 and we get 70%

Answer:

70%

Step-by-step explanation:

7 out of 10 rectangles were filled so that's 7/10. 7/10 also equals 70/100. Therefore it's 70 out of 100 or 70%.

Answer:

Step-by-step explanation:

we have 2 area rugs, and each has a length of 4 yards

Rug 1 has a area of 16 square yards, meaning that the width is also 4 yard(L*w=16, where Length=4)

Rug 2 has a Length of L=4 but the area is just 12 square yards, so here we have the width of 3 yards (12/4=3)

the rug number 2 will fit in tucker's bedroom

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the raw score is above or below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma} \\\\for\ a \ sample(n):\\\\z=\frac{x-\mu}{\sigma/\sqrt{n} }\\\\where\ x=raw\ score,\mu=mean, \sigma=standard deviation[/tex]

Given that n = 49, μ = 260 mg/dL, σ = 35 mg/dL

a) For x < 210:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{210-260}{35/\sqrt{49} } =-10[/tex]

From the normal distribution table, P(x < 210) = P(z < -10) = 0.0001

b) For x > 205:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{205-260}{35/\sqrt{49} } =-11[/tex]

For x < 215:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{215-260}{35/\sqrt{49} } =-9[/tex]

P(205 < x < 215) = P(-11 < z < -9) = P(z < -9) - P(z < -11) = 0.0001 - 0.00001 = 0.00009

c) For x < 200:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{200-260}{35/\sqrt{49} } =-12[/tex]

From the normal distribution table, P(x < 200) = P(z < -12) = 0.00001

d) For x > 222:

[tex]z=\frac{x-\mu}{\sigma/\sqrt{n} } =\frac{222-260}{35/\sqrt{49} } =-7.6[/tex]

From the normal distribution table, P(x > 200) = 1 - P(z < -12) = 1 - 0.0001 = 0.9999

[tex] \boxed{ \tt{the \: dimensions \: are : }}\\ \boxed{ \tt{b = 9 \: meters} }\\ \boxed{ \tt{l = 20 \: meters}}[/tex]

[tex]5 {s}^{2} = (3 + s) \times (14 + s) \\ 5 {s}^{2} = {s}^{2} + 17s + 42 \\ {4s}^{2} - 17s - 42 = 0 \\ s = \frac{ - ( - 17) + \sqrt{ {( - 17)}^{2} - 4(4)(42)} }{2(4)} \\ s = \frac{17 + 31}{8} \\ s = 6 \\ hence \to \:the \: dimensions \: are : \\ b = s + 3 = 6 + 3 = 9 \: meters \\ l = s + 14 = 6 + 14 = 20 \: meters[/tex]

The new dimensions of the pool are; Width = 9 and Length = 20.

A rectangular prism is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

It is given that the square pool was turned into a rectangular one and it's area was enlarged by a factor of 5 by enlarging one side of the pool by 3 meters and the other side by 14.

[tex]5s^2 = (3+s)(14 +s)\\\\5s^2 =s^2+ 17s + 42\\\\4s^2 - 17s - 42 = 0\\\\[/tex]

The root of the expression;

[tex]s = \dfrac{-(-17) + \sqrt{-17^2 - 4(4)(42)} }{2(4)} \\\\s = 6[/tex]

The dimensions are;

Width = 3 + s = 9

Length = 14 + s = 20

Answer:

P = A*0.40 + B*0.40

Step-by-step explanation:  Ok so, A is our apples right? THis would be our variable. As we sell more apples, the variable increases which means that our profits must add up for every one of those apples we sell. Repetive addition is multiplication, and it works perfectly for our scaling. Turns out this can also be used for the banana's because it's almost the same for the apples. However, it wants the TOTAL profits, which means we add the profits from the apples and banana's together.

Answer:

Hey the answer is 20%.

Step-by-step explanation:

You multiply the $90 with 20%,

but in order to figure that out you need to:

Calculate the savings: 20% of $90 = $18.

Subtract the savings from the original price to get the sale price: $90 - $18 = $72. You're all set!

Answer: 2/12 --> 1/6

3/2 --> 1 1/2

Step-by-step explanation:

2/12 can be simplified by dividing the top by 2 and the bottom by two. 2 is the GCF (greatest common factor) of both 2 and 12.

3/2 is a improper fraction so you have to make it a proper fraction. To do that you get 1 and 1/2.  <-- this is for simplest form.

Hope this helped!

We are given the following information:

each person uses 3/8 a box

there are 6 boxes

Because each box is , and there are 6 boxes, we know that 1 person is , or .

In order to find how many people can use the 6 boxes, we can divide it by 3 (for each use):

48 / 3 = 16

Therefore, 16 people can share the worms.

Step-by-step explanation: Brandon .w.

Answer:

thus the father is 64 years and son is 37years

Step-by-step explanation:

Let father be X and son be y

X=27+Y...........(I)

X-10=2(Y-10)

putting the value of X from eqn(I)

27+Y-10=2Y-20

Y+17=2Y-20

17+20=2Y-Y

37=y

X=27+Y

X=64

Answer:

[tex]A= 53[/tex]

Step-by-step explanation:

Given

[tex]BC = 9,6[/tex]

[tex]AC = 7.2[/tex]

Required: Angle A

This is calculated using:

[tex]tan\ A = \frac{Opposite}{Hypotenuse}[/tex]

From the attachment;

[tex]Opposite = 9.6[/tex]

[tex]Adjacent = 7.2[/tex]

So:

[tex]tan A =\frac{9.6}{7.2}[/tex]

[tex]tan A =1.333[/tex]

Take arctan of both sides

[tex]A= tan^{-1}(1.333[/tex]
