the five classes at steam elementary are going to the zoo. the teacher need to put the students in group of tens the number of students in each class is shown​

Ratio-wise it is the same :)

They're just moving decimals

.42 : .02

4.2 : .2

42 : 2

420 : 20

Answer:

(a) No

(b) No

(c) No

Step-by-step explanation:

Given

See attachment

Required

Select Yes or No for each

To do this, we make use of Euler's formula

[tex]F + V - E = 2[/tex]

Where

[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]

[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]8 + 12 - 6 = 2[/tex]

[tex]14 = 2[/tex]

The above equality is false. Hence, (a) does not exist

[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]6 + 6 - 4 = 2[/tex]

[tex]8 = 2[/tex]

The above equality is false. Hence, (b) does not exist

[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]

Using: [tex]F + V - E = 2[/tex]

[tex]20 + 30 - 12 = 2[/tex]

[tex]38 = 2[/tex]

The above equality is false. Hence, (c) does not exist

Answer:

Distance of ladder from base = 4.22 feet (Approx.)

Step-by-step explanation:

Given:

Length of ladder = 10 feet

Angle with ground = 65°

Find:

Distance of ladder from base

Computation:

Length of ladder (hypotenuse) = 10 feet

Distance of ladder from base (Base)

Using trigonometry function

Cosθ = Base / Hypotenuse

Cosθ = Distance of ladder from base / Length of ladder

Cos65 = Distance of ladder from base / 10

0.4226 = Distance of ladder from base / 10

Distance of ladder from base = 0.4226 x 10

Distance of ladder from base =  4.226

Distance of ladder from base = 4.22 feet (Approx.)

Answer:

$2800

Step-by-step explanation:

6/100 x 2500 = 150

150 x 2 = 300

2500 + 300 = $2800

Answer:

147.92

Step-by-step explanation:

Let the monthly salary be x

He saves 12 % and that is 17.75

x* 12% = 17.75

Change to decimal form

x *.12 = 17.17

Divide each side by .12

x*.12 /.12 = 17.75/.12

x =147.91666666

Rounding to the nearest cent

x = 147.92

Answer:

10 %

Step-by-step explanation:

Answer:

[tex]a) \frac{ - 8}{7} [/tex]

[tex]b) \frac{0}{1} [/tex]

[tex]c) \frac{7}{3} [/tex]

hope it helps you:)

Answer:

8%

Step-by-step explanation:

We can solve this by making use of the simple interest formula

I= PRT/100

480= 3000×R×2/100

480= 6000R/100

Cross multiply

48000= 6000R

R= 48000/6000

= 8%

Hence the rate is 8%

Answer:

Student C

Step-by-step explanation:

The fraction ends up being 3 and you get 3* 3^-1 so you add 1 to the exponent.

Answer:

5+5x-(3x-9)

5+5x-3x+9

2x+14

2(x+7)

Step-by-step explanation:

Answer:

2x+14

explanation:

5+5x-(3x)--9

5+5x-3x+9

add 5 and 9 to get 14

then subtract 3x from 5x to get 2x

2x+14

Answer:

6540.85

Answer:

$765

Step-by-step explanation:

Given data

Principal= $750

Rate= 2%

Time= 1 year

The simple interest expression is given as

A=P(1+rt)

substitute

A= 750(1+0.02*1)

A= 750(1.02)

A= $765

Hence the final amount is $765

Answer:

Hello, so the answer is 21.

Step-by-step explanation:

Okay so first we want to do it order, so the order you do it in is the order of PEMDAS which stands for  Parentheses, Exponents, Multiplication, Division , Addition and Subtraction.

So in this situation we have parenthesis, multiplication, subtraction and addition, so we start with the parenthesis, (8 x 3) which is 24. So then we move on to +6 (positive six) and -9 (negative 9) basically -9 minus 6 is -3.

Sooo now we have -3 and 24. The three is negative because -9 minus 6 is -3, and you have to put the sign of the bigger number.

Now, 24 minus 3 equals 21. So there we have it :)

Hope I helped!

ITS BIASED IM REALLLLY SURE

Step-by-step explanation:

Answer: 1/12

Step-by-step explanation:

First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.

1/4 x 3/3 = 3/12

2/3 x 4/4 = 8/12

then you have 3/12 + 8/12 = 11/12

so, blue is 1/12

Answer:

1/12 of the pins are blue

Step-by-step explanation:

¼ yellow & ⅔ red

First you have to find a common denominator.

4×3 =12 & 3×4 =12 so the common denominator is 12.

Now × the numerator on the fraction with the same number that you x the denominator and you will get 3/12 and 8/12.

3/12 +8/12 = 11/12

12/12 - 11/12 = 1/12

Therefor 1/12 of the pins are blue
