Evaluate 8a- 1 + 0.5b when a = 1/4 and b = 10

Answer:

B) 28 cm^2

Step-by-step explanation:

First, find the perimeter 5*4=20

A= ½ 2.75(20) = 27.5

(round to the nearest whole number)

Got it right on the test

2 = 9

9 ÷ 2 = 4.5

4.5 x 6 = 27

It will cost 27 pounds.

Hope this helps; have a great day!

Answer:

6

Step-by-step explanation:

Answer:

Step-by-step explanation:

We can use the pythogorean theorem which is,

[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]

Where c = Hypotenuse

b and a = Legs of the triangle

We have to find the hypotenuse. So let's keep the value of it as x.

we can form an algebraic equation to solve for x

[tex] {15}^{2} + {8}^{2} = {x}^{2} \\ 225 + 64 = {x}^{2} \\ 289 = {x}^{2} \\ x = \sqrt{289} \\ x = 17[/tex]

Answer:

A - they are vertical angles so they are equal to each other

b - dont really know this one

c - y=24 and 7 and 8 = 89

Step-by-step explanation:

You messed up because the angles given are not supplementary the angles given that are next to 7 and 8 are vertical then we can setup an equation which would be 5y-29=3y+19 and solve for y

step 1 add 29 to each side

5y=3y+48

step 2 subtract each side by 3y

2y=48

step 3 divide each side by 2

y=24

then we plug in 24 to one of the expressions

5(24)=120

120-19=101

but we are not done yet because it is asking for the value of angle 7 and 8

because angle 7 is supplementary to both all we have to do is subtract 101 from 180

180-101=89 so 7 and 8 =89

hope this helps :D

Answer:

[tex]n = 7[/tex]

Step-by-step explanation:

Given

[tex]\bar x = 8[/tex] --- the mean

[tex]\sum x = 56[/tex] --- sum of scores

Required

The number of scores (n)

This is calculated as:

[tex]\bar x = \frac{\sum x}{n}[/tex]

Make n the subject

[tex]n = \frac{\sum x}{\bar x}[/tex]

[tex]n = \frac{56}{8}[/tex]

[tex]n = 7[/tex]

Step-by-step explanation:

Answer:

x=115

Step-by-step explanation:

Straight angle = 180 degrees...

65 is accounted for so...

180-65=115

115 degrees is your final answer :)

Answer:

115

Step-by-step explanation:

x° = 180° - 65°

(Linear pair angles)

x° = 115°

x = 115

Boundary points are NOT always solutions

The statement  not true about the boundary line in the graph of a linear inequality in two​ variables is he point on boundary line are always solutions to the linear inequality

The graph of an inequality in two variables is the set of points that represents all solutions to the inequality. A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥.

According to the question

Hence, The statement  not true about the boundary line in the graph of a linear inequality in two​ variables is he point on boundary line are always solutions to the linear inequality.

Answer:

8

Step-by-step explanation:

Answer: Diameter: 8

              Area:  201.1

Step-by-step explanation:

Diameter: Use the formula for the area of a circle:

Use the formula for the area of a circle:

A=πr2

Here, the area is 16π:

16π=πr^2

Divide both sides by  π:

16=r^2

Take the square root of both sides:  √16=√r^2

4=r

Since the radius of the circle is 4, the diameter is twice that:

d=4×2=8

Area:

Formula:

A = π r^2

A= Area R= Radius

Add Radius

A= π 8^2

Solve:

Triangular prisms

Remember the formula for calculating volume is: Volume = Area by height. V = A X h.

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h

Answer:

B. 20

Step-by-step explanation:

We need to find a common denominator for 1/5, 1/3, and 3/10, which would be 30. 1/5 = 6/30, 1/3 = 10/30, and 3/10 = 9/30. If we add these together we get 25/30. This leaves 5/30 covered in sprinkles.

Now we need to find what 5/30 of 120 is. We can simplify 5/30 to 1/6. 120 divided by 6 is 20. So, 20 apples are covered in sprinkles.

Answer:

A. 12

Step-by-step explanation:

Recall: one of the properties of a parallelogram is that the diagonals bisect each other. This means that:

LJ = 2(LW)

11x + 2 = 2(5x + 2)

11x + 2 = 10x + 4

11x + 2 - 2 = 10x + 4 - 2

11x = 10x + 2

11x - 10x = 10x + 2 - 10x

x = 2

✅LW = 5x + 2

Plug in the value of x

LW = 5(2) + 2

LW = 10 + 2 = 12
