Mauricio takes 24 hours, and Alyson takes 24/5 hours if the Mauricio does a job in 6 hrs less time than Alyson.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let x and y be the time to take the job for Mauricio and Alyson respectively

1/x = 1/y - 1/6 ..(1)

1/x + 1/y = 1/4 ..(2)

After solving the equations:

[tex]\rm \dfrac{1}{\dfrac{6y}{6-y}}+\dfrac{1}{y}=\dfrac{1}{4}[/tex]

y = 24/5 hours

x = 24 hours

Thus, Mauricio takes 24 hours, and Alyson takes 24/5 hours if Mauricio does a job in 6 hrs less time than Alyson.

Answer:

x = 90

Step-by-step explanation:

In this figure the exterior angle is 130°

An exterior angle is the sum of the interior angles. The interior angles are x and 40 so x + 40 = 130 giving x = 130-40 = 90

Answer:

∠ x = 90°

(90 degrees)

Step-by-step explanation:

When two angles combine to make a straight line, we know that their angle values must add up to 180

Here, we can see that 130 combines with an inner angle to form a straight line. (I will be calling this interior angle z )

So, 130 + z = 180

   130 + z = 180

 - 130        -130

   z = 50

We also know that all angles in a triangle must add up to 180 degrees, and because we know the two other angles of our triangle now, we can find x

z + x + 40 = 180

50 + x + 40 = 180

90 + x = 180

- 90           -90

x = 90

So, the measure of angle x is 90°

hope this helps!! have a lovely day :)

Answer:

1st option

Step-by-step explanation:

the area of the shaded portion is calculated as

area of sector - area of white Δ

area of sector = area of circle × fraction of circle

                        = πr² × [tex]\frac{90}{360}[/tex] ( r is the radius )

                        = π × 8² × [tex]\frac{1}{4}[/tex]

                       = 64π × [tex]\frac{1}{4}[/tex]

                       = 16π in²

area of Δ = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = h = 8

area of Δ = [tex]\frac{1}{2}[/tex] × 8 × 8 = [tex]\frac{1}{2}[/tex] × 64 = 32 in²

Answer:

132 inches squared

Step-by-step explanation:

Area is 132 inches squared

Method 1:

Area of parallelogram = base x height = 11inches x 12 inches = 132 inches squared

Method 2:

Move the triangle divided by the dotted line on the right to the left.

It becomes a rectangle of 11 inches by 12 inches. 11 inches x 12 inches = 132 inches squared.

The number of Apples that were in the given fruit salad is approximately; 2170 Apples.

We are given the ratio of apples to oranges as;

A:O = 31:11

Now, we are told that there are 2940 apples and oranges in total.

Thus, the fractions of apples and oranges of the total will be;

Apple fraction = 31/(31 + 11) = 31/42

Orange Fraction = 11/42

Thus;

Number of Apples = (31/42) * 2940

The cooper's weight as an adult dog will be 90 pounds.

Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.

A typical method for calculating a percentage is the formula shown below:

Calculation for the weight of Cooper as an adult;

Cooper's present weight is 20 pounds.

He will weigh about 350% as much as his current weight.

Calculate 350% of 20 pounds.

= (350×20)/100

= 70

The increment of the weight of Cooper will be 70 pounds.

Thus, the total weight is 20 + 70 = 90.

Answer: 30506.49303

Step-by-step explanation:

The value of the missing triangle sides and angles are XY = 20.9, YZ = 12.4 and ∠Y = 119°

An equation is an expression that shows the relationship between two or more numbers and variables.

Sine rule is used to show the relationship between the sides and angles of a triangle.

In the triangle XYZ:

∠X + ∠Y + ∠Z = 180° (sine rule)

22 + 39 + ∠Y = 180

∠Y = 119°

Using sine rule:

XY / sinZ = XZ / sinY

XY / sin(39) = 29 / sin(119)

XY = 20.9

Also:

YZ / sinX = XZ / sinY

YZ / sin(22) = 29 / sin(119)

YZ = 12.4

The value of the missing triangle sides and angles are XY = 20.9, YZ = 12.4 and ∠Y = 119°
