Answer:

there are 4 groups of 3

Step-by-step explanation:

12 ÷ 3 = 4

answer : 4

Step-by-step explanation:

12 = 3 + 3 + 3 + 3 there are 4 groups of 3

a³ + b³ + c³ + 3abc = ( a + b + c)(a² + b² + c² + ab + bc + ca)

if a + b + c = 0. then a³ + b³ + c³ = 3abc

here a + b + c = 15 + (-9) + (-6)

a + b + c = 15 - 15

a + b + c = 0

so a³ + b³ + c³ = 3abc

15³ + (-9)³ + (-6)³ = 3(15)(-9)(-6)

= 2430

so the answer is 2430

Answer:

10

Step-by-step explanation:

it is because when you use a scientific calculator you get 10.09950494

which would be round to 10 because after the decimal the number is 0 below 5 so 10 stays as 10

hope this helps

The best approximation for the value of √102 is: 10.

The square root of 102 is:

√102

=10.09950494

Now if we approximate 10.09950494 it would give us:

Approximation= 10.09950494

Approximation= 10 (Approximately)

Therefore The best approximation for the value of √102 is: 10.

Answer:

23.6 units

Step-by-step explanation:

If we have a circle of radius R, the perimeter of the arc is given by:

P = 2*pi*R

Now, if we only want to find the length of an arc defined by an angle "a", it will be:

L = (a/2*pi)*2*pi*R = a*R

In this case, we know that DA = 10, so we can think that this is a circle of radius R = 10 units

And for the arc DE, we have the angle:

a = 2.36 rad

replacing these two in the formula, we get:

L = 2.36*10 units = 23.6 units

Answer:

flour 720 g

salt 10.8 g

yeast 14.4 g

oil 36 ml

water 600 ml

Step-by-step explanation:

600 ml - 500 ml = 100 ml = 20% more

Set up ratios to determine 20% of each ingredient and add to the original amount.

Example:

20%/100% = x ml/30 ml

20x30÷100=6

So, for oil, you need 30 ml + 6 ml = 36 ml

6 ml = 20% more

Answer:

Triangle RSP is similar to triangle ZXY

Step-by-step explanation:

to be similar triangles the order of the angles must match.

Angle R is 41° so is angle Z

angle S is 54° so is angle X

Answer: 0.43ft²

Step-by-step explanation:

You didn't really specify part A but In assuming that the question you posted is part A. Anyways in this case, area will be calculated by multiplying the length by the width.

Since the piece of wood has a length that is 2.45 feet and width that is 2.097 inches, then the area will be:

= 2.45 × 0.17475

= 0.4281375 ft²

= 0.43ft² to nearest hundredths

Note 1 foot = 12 inches

Therefore, 2.097 inches = 2.097/12 = 0.17475 feet

[tex]\text{C. }g(x)=(x-5)^2[/tex]

Step-by-step explanation:

The function [tex]y=(x-c)^2[/tex] has a phase shift of [tex]c[/tex] to the parent function [tex]y=x^2[/tex]. Since [tex]g(x)[/tex] has moved to the right 5 units from the parent function [tex]f(x)=x^2[/tex], we're looking for a value of [tex]c=5[/tex].

Therefore, we have:

Answer:

12.4 feet

Step-by-step explanation:

A ladder placed against the wall forms a right angle triangle

Hypotenuse ² = opposite ² + adjacent ²

Hypotenuse = 13 feet

Opposite = 4 feet

Adjacent = x

Hypotenuse ² = opposite ² + adjacent ²

13² = 4² + x²

169 = 16 + x²

169 - 16 = x²

153 = x²

Find the square root of both sides

√153 = √x²

12.369316876852 = x

x = 12.4 feet

Adjacent = x = 12.4 feet

Answer:

Step-by-step explanation:

Fraction to make topping:

1/4 cups of white ; 2/3 cups of brown

Combined = 1/4 + 2/3 = (3 + 8) /12 = 11/12 cups

Fraction of combined used to top muffin = 1/12

Number of muffins that can be topped per combination made :

11/12 ÷ 1/12 ; 11 /12 * 12 / 1 = 11 muffins

Recall :

Each sugar has 11 1/3 cups

For brown sugar :

34 /3 ÷ 2/3 cups

34 /3 * 3 /2 = 17

For white sugar :

34 /3 * 4 /1 = 45.33

However, the highest amount of combined muffin topping for white sugar will be restricted by the number of brown :

Hence,

11 muffins can be topped from each combined mixture ;

Total muffin that can be topped :

17 * 11 = 187 muffins

a - and a - equal a +, so it's 5xy+3xy, which equels 8xy.

Answer:

W ≈ 5.2 cm

Step-by-step explanation:

Represent the length and width by L and W respectively.

Then L * W = 81 cm^2, and L = 3W.

Substituting 3W for L in the first equation, we get:

3W * W - 81 = 0, or 3W^2 - 81 = 0.

To make it easier to find the final answer, rewrite 3W^2 - 81 = 0 as

            81

W^2 = ------- = 27

              3

Then W (the width) is the positive square root of 27, or W ≈ 5.2 cm

Answer:

60.75 ≈ 60.8
