Answer:

Maggie is 13 years old.

Step-by-step explanation:

Maggie's age is: x

Maggie's brother's age is: 2x - 3

The sum of the ages = 36

x + 2x - 3 = 36

3x - 3 = 36

3x = 39

x = 13

Answer: Maggie is 13 years old.

Answer:

[tex]\frac{11}{12}[/tex],[tex]1\frac{1}{4}[/tex],[tex]1\frac{2}{3}[/tex]

Step-by-step explanation:

It wants you to take these 3 fractions and arrange them from least to greatest.

The first thing I did was look for the fraction with no number in front of it.

[tex]\frac{11}{12}[/tex] is the only fraction that has no numbers in front of it. So

The second thing I did was look for the fraction that had the biggest number in front of it. I see that the remaining fractions have the same number in front.

So, I drew 2 circles. 1 of the circles I shaded in and the other I split into 4 equal halves. I shaded in one of the halves. These 2 circles represent [tex]1\frac{1}{4}[/tex].

The next thing I did was draw 2 more circles. I shaded in one of them and slit the other one into 3 equal halves. I shaded in 2 of the halves. These 2 circles represent [tex]1\frac{2}{3}[/tex].

Last, look at the 4 circles and ask yourself which one is the most shaded in. If you said [tex]1\frac{2}{3}[/tex] you are correct. This fraction is the biggest. Meaning that [tex]1\frac{1}{4}[/tex] is in the middle.

Answer:

  80 units

Step-by-step explanation:

The sides of a regular octagon are all the same length.

  x +6 = 14 -x

  2x = 8 . . . . . . add x-6

  x = 4

  x+6 = 10 . . . . the length of each of the 8 sides

P = 8s = 8(10) = 80

The perimeter of the octagon is 80 units.

2) Substitute 3-y/2 in the equation -8x+ay=-11

3) Then we simplify

4) Isolate for y

5)Then we simplify in order to get -4

Answer:

0.75 hour or 45 mins

Step-by-step explanation:

From the question, we are told that:

Speed of Train A = 84 miles per hour. Speed of Train B = 92 miles per hour.

Total speed travelled by both trains =

84mph + 92mph

= 176 mph

The distance between the two stations = 132 miles.

We are asked in the question to: find out how long after they leave their respective stations do the trains meet.

This means we should calculate the time

Time = Distance/ Speed

= 132 miles/176 miles per hour

= 0.75 hour

We can convert to minutes if we like

1 hour = 60 minutes

0.75 hour =

0.75 hour × 60 minutes/ 1 hour

= 45 minutes

Therefore, the trains meet after 0.75 hour or 45 minutes after they have left their respective stations.

Answer:

7,425 gallons of water

Step-by-step explanation:

Given:

A tank of,

Length = 16.5 ft

Width = 7.5 ft

Height = 8 ft

1 ft³ = 7.5 gallons of water

Required:

Gallons of water that will fill the tank

SOLUTION:

Find the volume of the tank:

Volume of the tank = length*width*height

Volume = 16.5*7.5*8 = 990 ft³

Convert 990 ft³ to gallons of water:

1 ft³ = 7.5 gallons

990 ft³ = [tex] 990*7.5 [/tex]

= 7,425 gallons of water

7,425 gallons of water will fill the tank of the given measurement.

Amount of water in tank is 7,425 gallon

Given that;

Sides of tank = 16.5 ft, 7.5 ft, 8 ft

1 ft³ = 7.5 gallon

Find:

Amount of water in tank

Computation:

Volume of tank = [(16.5)(7.5)(8)]

Volume of tank = 990 ft³

Amount of water in tank = [Volume of tank][7.5]

Amount of water in tank = [990][7.5]

Amount of water in tank = 7,425 gallon

Answer:

Step-by-step explanation:

3 (-4 x - 1) - 2 x + 4 = 43

Expand the terms in the bracket

That's

- 12x - 3 - 2x + 4 = 43

- 14x + 1 = 43

Using the subtraction property subtract 1 from each side of the equation

- 14x + 1 - 1 = 43 - 1

- 14x = 42

Divide both sides by - 14

[tex] \frac{ - 14x}{ - 14} = - \frac{42}{14} [/tex]

Step-by-step explanation:

Answer:

22*3=66

Flase

Step-by-step explanation:

The equation ((22)3) = 25 is false.

Two or more expressions with an Equal sign is called as Equation.

The given equation is  ((22)3) = 25.

We have to check whether the left hand side is equal to right hand side.

If the LHS and RHS are equal then the equation is true.

If not then it is false.

The value in LHS is 22×3 = 66

The value in RHS is 25

66 is not equal to 25

Hence, the equation ((22)3) = 25 is a false statement.

Answer:

The first element of a set which is linked with the element of second set is called domain.

The element of second set is known as range.

Answer:

When functions are first introduced, you will probably have some simplistic "functions" and relations to deal with, usually being just sets of points. These won't be terribly useful or interesting functions and relations, but your text wants you to get the idea of what the domain and range of a function are. Small sets of points are generally the simplest sorts of relations, so your book starts with those.

for example

State the domain and range of the following relation. Is the relation a function? {(2, –3), (4, 6), (3, –1), (6, 6), (2, 3)}

The above list of points, being a relationship between certain x's and certain y's, is a relation. The domain is all the x-values, and the range is all the y-values. To give the domain and the range, I just list the values without duplication:

domain: {2, 3, 4, 6}

range: {–3, –1, 3, 6}

(It is customary to list these values in numerical order, but it is not required. Sets are called "unordered lists", so you can list the numbers in any order you feel like. Just don't duplicate: technically, repetitions are okay in sets, but most instructors would count off for this.)

While the given set does indeed represent a relation (because x's and y's are being related to each other), the set they gave me contains two points with the same x-value: (2, –3) and (2, 3). Since x = 2 gives me two possible destinations (that is, two possible y-values), then this relation is not a function.

Answer:

153.2 =x

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

cos theta = adjacent side/ hypotenuse

cos 40 = x/200

Multiply each side by 200

200 cos 40 = x/200 * 200

200 cos 40 =x

153.20888886=x

To the nearest tenth

153.2 =x

Answer:

AC = 153.2 m.

Step-by-step explanation:

cos(Ф) = adj / hyp

cos(40) = AC / 200

AC = cos(40) x 200

AC = 153.2 m

Answer:

14.99 ounces

Step-by-step explanation:

First, find the weight of the 2 cereal bags combined:

16.03 + 18.98

= 35.01

Subtract this from 50 to find the weight of the box, since 50 ounces is the combined weight of the box and the 2 cereal bags

50 - 35.01

= 14.99

So, the box weights 14.99 ounces
