A right square has a height of 13 centimeters and a base of 16.4 centimeters what the area of the triangle

Answer:

x = -13

Step-by-step explanation:

2x + 6 = -20

Subtract 6 on both sides.

2x = -26

Divide by 2 on both sides.

x = -13

Answer:

-13

2x + 6 = -20

2x =  -26

x = -26 / 2

x=-13

Answer: 31

Step-by-step explanation:

Janine has 48 hockey cards in one book and 105 hockey cards in another book. Therefore, the total hockey cards will be:

= 48 + 105

= 153 hockey cards

Since the hockey cards come in packages of 5 cards, the number of packages that she will buy will be:

= 153/5

= 30 3/5

= 31

Therefore, she'll buy 31 packages

Answer:

both of the above

Step-by-step explanation:

The correct representation of the graph will be;

''The cost of gas rises, and then doesn't change for while. The cost falls before finishing with a sharp increase.''

Option B is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The graph is shown in figure with relation between Time and Cost.

Now,

In the graph;

From the start, The cost of gas is rise with increase in graph, and then in cost no change occur with constant line.

The, the cost falls with falls in graph and then the cost is sharp increase before finishing.

Thus, The correct representation of the graph will be;

''The cost of gas rises, and then doesn't change for while. The cost falls before finishing with a sharp increase.''

Move all terms not containing y to the right side of the

equation.

y= X/2+4

Rewrite in slope-intercept form.

y=1/2x+4

Use the slope-intercept form to find the slope and y

intercept.

Slope: 1/2

y-intercept: (0,4)

Any line can be graphed using two points. Select two x values, and plug them into the equation to find the corresponding y values. Answer: (0,4) (2,5)

Answer:

2/3 miles

Step-by-step explanation:

this question is basically asking you to find the slope between two points: (4,3) and (-2, -1)

how to find slope: (y1 - y2)/ (x1-x2)

so:

y1 =3, y2= -1

x1 = 4, x2 = -2

Step-by-step explanation:

By forming a right triangle, we can see that the angle of elevation is 30°.

In a 30-60-90 triangle, the side opposite the 30° is the other leg multiplied by 1/√3.

x= [tex]\frac{3}{\sqrt{3} } =\frac{3\sqrt{3} }{\sqrt{3}*\sqrt{3} } =\frac{3\sqrt{3} }{3} =\sqrt{3}[/tex]

The height of the pole is (√3+1.4)m

Answer:

80 degrees

Step-by-step explanation:

one half of the circle makes a straight line and that will equal 180 degrees so 60+45=105

180-105=80

so the missing angle is x=80

Answer:

x = 75 degrees

Step-by-step explanation:

60 + 60 = 120

45 + 45 = 90

120 + 90 = 210

360 - 210 = 150

150 / 2 =75 degrees

The required shortest between the two houses is given as 10 miles. Option B is correct.

In a right-angled triangle, its side, such as the hypotenuse, is perpendicular, and the base is Pythagorean triplets.

Here,
Matthew lives 6 miles east of the school drew lives 8 miles north of the school.

Let's assume, the position of Mathew and drew house create the right angle with the school,
hypotenuse distance between Mather and Drew's house be x,
Applying the Pythagoras theorem,

x = √[8² + 6²]
x = √[100]
x = 10 miles

Thus, the required shortest between the two houses is given as 10 miles. Option B is correct.

Answer:

16 cupcakes

Step-by-step explanation:

Amount Alex wants to spend = $25

Cost of each cupcake = $1.50

what is the max number of

cupcakes that Alex can buy without going over his $25 limit?

Let

x = maximum number of cupcakes Alex can buy

Amount Alex wants to spend = Cost of each cupcake * maximum number of cupcakes Alex can buy

25 = 1.50x

x = 25 / 1.50

x = 16.67

The maximum number of cupcakes that Alex can buy without going over his $25 limit is 16 cupcakes as a whole

so what is really the answer?

Answer:

68°

Step-by-step explanation:

Equations:

To solve for y we have to use the sine rule which is defined as:

[tex]\frac{sinA}{a} =\frac{sinB}{b} =\frac{sinC}{c}[/tex]

Side a is opposite from angle A, side b is opposite from side B, etc.

Solving for y:

Let's say angle A was the angle we are trying to find. Then we can re-write the sine rule as:

[tex]\frac{sin(y)}{250} =\frac{sin(48)}{200}[/tex]

Let's re-arrange this for the angle y:

[tex]sin(y)=250 * \frac{sin(48)}{200} \\y=sin^-1(250 * \frac{sin48}{200} )[/tex]

Typing this into a calculator gives the answer: [tex]y = 68.26...[/tex] which is 68 degrees rounded to the nearest whole degree.

Radius of inner circle = r

Radius of entire circle = r + r + r + r + r = 5r

Probability that an arrow hitting the target will land on inner circle ;

Area of inner circle / area of entire circle

Area of circle = πr²

Hence ;

πr² / π(5r)²  = πr² / π25r² = 1 / 25 = 0.4

Answer:

Step-by-step explanation:

Given

[tex]f(x) = 0.85x + 3.99[/tex] ---company A

[tex]g(x) = 1.10x[/tex] --- company B

Required

Value of x when [tex]f(x) = g(x)[/tex]

We have:

[tex]f(x) = g(x)[/tex]

[tex]0.85x + 3.99 = 1.10x[/tex]

Collect like terms

[tex]0.85x - 1.10x = -3.99[/tex]

[tex]-0.25x = -3.99[/tex]

Solve for x

[tex]x = \frac{-3.99}{-0.25}[/tex]
