Ratio of number of boys to total number of children is 3:4 and number of girls is 8

The comparison of two values using the same unit is called a ratio. Divide the first amount by the second to get it. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0.

Let the number of boys be 3x and girls be x.(As they are in ratio of 3:1)

a) Total number of children = 3x + x = 4x

Ratio of number of boys to total number of children = [tex]\frac{3x}{4x}[/tex]

= 3:4

b) As, number of boys are 24

3x = 24

x = 8

, number of girls = x = 8

Answer: 7 -(-3)=7+3=10

Step-by-step explanation:

If you multiply a negative sign be a negative number in parenthesis, then it becomes positive. So, -(-3) = 3

Can also be seen as -1*-3 = 3

The percentage of customers who chose whole wheat bread with turkey are 19 %.

Given that:-

Percentage of customers who preferred white bread = 55 %

Percentage of customers who preferred turkey with white bread = 46 % of those who like white bread.

Percentage of customers who preferred ham with whole wheat bread = 55 %

We have to find the percentage of customers who chose whole wheat bread with turkey.

Let the total number of customers at the local sandwich shop be 100x.

Percentage of customers who preferred whole wheat bread = (100-55) % = 45 %

45 % of 100x = 45x.

Percentage of customers who preferred turkey with whole wheat bread = (100-58) % of 45x = 42 % of 45x.

42 % of 45x = 18.9x ≈ 19x.

19x is 19 % of 100x.

Answer: The answer is A, 19%

Step-by-step explanation: I had the same question.

Answer:

y=-5x+6

Step-by-step explanation:

the two lines are parallel so they have the same slope and if you put the like in y=mx+b it would be y=-5x+1 so the slope is -5

Then you need to put it into point slope for to figure it out y-y1=m(x-x1)

y-1=-5(x-1) (simplify)

y-1=-5x+5 (add 1 to both sides)

y=-5x+6

The distributive property should be used to rewrite each expression without parenthesis as follows:

The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a specific number, the same output (result) would be produced as when each addend is multiplied respectively by the number, and the products are added together.

Mathematically, the distributive property of multiplication is given by this expression:

a(b + c) = ab + ac.

In conclusion, the distributive property of multiplication can be used to evaluate and rewrite a mathematical expression as shown above.

We divide 3 by 20:-

3 / 20 = 0 so we divide 30 by 20 and proceed as below:

20)3.00 ( 0.15

     20

      100

      100

The answer is 0.15 which is terminating.

If we divide as above we get 0.45454545....

The 45 keeps repeating

2/15

Dividing gives 0.133.........

7/8 = 0.875

terminating.

9/16

= 0.5625

terminating.

Answer:

3/20 = 0.15 (Terminating)

5/11 = 0.45454 (Repeating)

2/15 = 0.13333 (Repeating)

7/8 = 0.875 (Terminating)

9/16 = 0.5625 (Terminating)

Explanation:

The definition of Terminate means to bring to an end. This would also apply to the decimals. To find whether a fraction is terminating or not, is to simply divide and you will get a decimal, unless it is mixed fraction. Terminating will bring an end, Ex: 1/2 ( 1 ÷ 2 ) which would equal = 0.5 This is an example of a terminating decimal. A repeating decimal is a decimal that never ends of its repetition, Ex: 0.13333333 (Continuous).

Answer:

x = 7.2 , y = 57 , z = 10.8

Step-by-step explanation:

the sum of the 3 angles in the outer triangle = 180° , that is

y + 88 + 35 = 180

y + 123 = 180 ( subtract 123 from both sides )

y = 57

------------

the outer and inner triangles are similar ( AA postulate ) then the ratios of corresponding sides are in proportion, that is

[tex]\frac{x}{12}[/tex] = [tex]\frac{9}{9+6}[/tex] = [tex]\frac{9}{15}[/tex] ( cross- multiply )

15x = 108 ( divide both sides by 15 )

x = 7.2

and

[tex]\frac{z}{18}[/tex] = [tex]\frac{9}{15}[/tex] ( cross- multiply )

15z = 162 ( divide both sides by 15 )

z = 10.8

Amount of water produced in 6 days is 15.6×10⁶.

We will simply perform multiplication to find the amount of water produced in 6 days.

Amount of water produced in 6 days = amount of water produced in one day × 6

Amount of water produced in 6 days = 2.6×10⁶×6

Performing multiplication to find the amount of water produced in 6 days

Amount of water produced in 6 days = 15.6×10⁶

The answer is in scientific notation as 15.6 is coefficient, 10 is base and 6 is exponent. Therefore, amount of water produced by plant in 6 days is 15.6×10⁶.

Swimmer is 47 dm away from the sailboat.

The mentioned problem will use cosine trigonometric functions to find the distance between swimmer and sailboat. Assuming the distance between lifeguard and swimmer be x and the distance between lifeguard and sailboat be y.

Taking the triangle between swimmer and lifeguard -

cos theta = base/hypotenuse

cos 32 = x/36.5

x = 0.8×36.5

x = 29.2 dm

Taking the triangle between lifeguard and sailboat -

cos 13 = y/84.7

y = 0.9×84.7

y = 76.23 dm

Therefore, the distance between sailboat and swimmer is y - x

Distance = 76.23 - 29.2

Performing subtraction

Distance = 47.03 dm

Round to nearest tenth

Distance = 47 dm

Thus, the sailboat and swimmer are 47 dm apart.

The sales in 2012 is estimated to be $40546.5 million if we use the midpoint formula assuming that the sales followed a linear pattern.

Midpoint is a term used in geometry and can be described as the center or middle point of a line segment. It enables you to take two endpoints, and then by using these endpoints you can find the point that is midway between them in the line segment.

Considering,

[tex]P_{1} = (x_{1},y_{1})[/tex]

[tex]P_{2} = (x_{2},y_{2})[/tex]

Here;

[tex]x_{1}[/tex] = 2010

[tex]x_{2}[/tex] = 2014

[tex]y_{1}[/tex] = $35,109 million

[tex]y_{2}[/tex] = $45,984 million

The formula for the midpoint is given as;

[tex]P_{m}[/tex] = {( [tex]x_{1} + x_{2}/2[/tex] ), ( [tex]y_{1} + y_{2} / 2[/tex] )}

[tex]P_{m}[/tex] = {(2010 + 2014 / 2), (35109 million + 45984 million / 2)}

[tex]P_{m}[/tex] = {(4024 / 2), (81,093 million / 2)}

[tex]P_{m}[/tex] = {2012 , 40546.5 million}

As a result, angle M's supplement is 167 degrees, while angle M's complement is 77 degrees.

Angles that add up to 180 degrees are referred to as supplementary angles. For instance, angle 130° and angle 50° are complementary angles since the sum of these two angles is 180°. The sum of complimentary angles is 90 degrees. If the two additional angles are combined, they create a straight line and an angle.

Complementary angles are those whose combined angle is 90 degrees or less. To put it another way, two angles are said to be complimentary if they combine to make a right angle. In this case, we say that the two angles work well together.

So as per the given information:

we know that

a).  180-angle M=supplement of angle M

180-13=167 degree

b).  90-angle M=compliment of angle M

    =77 degree

Therefore, the supplement of the angle M is 167 degree and the complement of angle m is 77 degree.

Given: x = -2; y = -3; z = 5

It is clear that a numerical term can only be evaluated from an expression filled with numbers (no variables). In the expression provided, we have two variables, where y is being subtracted from x.

The expression can't be simplified because there is no like terms in the expression. However, since there are specific numerical values for each variable, we can substitute the numerical values for the variables in the expression and simplify the expression.

As planned, let's substitute the variables into the expression

Here, we know that x = -2 and y = -3.

If -2 is being subtracted by a negative integer, the negative integer will become positive, and the "minus sign" will be converted to a "plus sign".

We can conclude that 1 is the solution to the expression.
