Answer:

B

Step-by-step explanation:

you got to divide it into different shapes so I divided it into three rectangles. Area of a rectangle is Length×Width so the first triangle was 2×3=6 the second was 1×2=2 and the third was 1×3=3 then u add them and u get 11.

Length length radius of a wheel in an inline skates = 41 millimeters

Circumference of wheel = Millimeters traveled by the wheel in one rotation

(pi value = [tex] \tt\: \frac{22}{7} [/tex])

Circumference of wheel :

[tex] = \tt2\pi r[/tex]

[tex] =\tt 2 \times \frac{22}{7} \times 41 [/tex]

[tex] = \tt \frac{2 \times 22}{7} \times 41[/tex]

[tex] = \tt \frac{44 \times 41}{7} [/tex]

[tex]\color{plum} =\tt 257.71 \: mm[/tex]

Thus, the wheel will travel 257.71 mm in one rotation.

Distance traveled by the wheel in 5 rotations :

= distance traveled by the wheel in 1 rotation × 5

[tex] =\tt 257.71 \times 5[/tex]

[tex]\color{plum} = \tt\bold{1288.55 \: mm}[/tex]

[tex] =\tt \frac{1288.55}{10} \: cm[/tex]

[tex] \color{plum}=\tt 128.855 \: cm[/tex]

▪︎Therefore, the distance traveled by the wheel in 5 rotations = 1288.55 millimeters or 128.855 cm.

The graph that represents the expression is given.

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way.

The relationships between two or more items are frequently represented by the points on a graph.

Given expression,

Let x be the amount Janice pays for rent and

y be the amount she pays for food.

Then,

rest of the budget is;

3850 - x -y

the function is,

y = 3850 - x

Therefore, the graph is given in the image.

Answer:

10 < 18 + 7

10 < 25

True yyes

cuz it is above 10

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

For a point to satisfy an inequality, when it is pluged in, the inequality must be true. So, first, plug in 3 for x and 10 for y. After plugging in the points the inequality is 10< 6(3)+7, then simplify the inequality. This equals 10<25, which is a true statement. Therefore the answer is yes.

Answer:

x=6

Step-by-step explanation:

you divide -25 on both sides

-25x=-150

divido todo por -25 lo que me da es

x=6

Answer:

0.416667 or [tex]\frac{5}{12}[/tex]

Step-by-step explanation:

Step-by-step explanation:

consider 61°=m angle 8

angle 1=angle 8........ corresponding angle

angle 1=61°

angle 2+angle 1=180°.........angles in linear pair

180-61

angle 2=119°

angle 3=angle 8 alternate angle

angle 3=61°

angle 4=angle 2............ opposite angles

angle 4=119°

angle 5=angle 4......... alternate angles

angle 5=119°

angle 6=angle 8......... opposite angles

angle 6=61°

angle 7=angle 5.......... opposite angles

angle 7=119°

Answer: 8 45 degree angles

Step-by-step explanation:

A circle is 360 degress. 360 divided by 45 equals 8

Answer:

8

Step-by-step explanation:

a circle is 360°. to find how many 45° angles it would take to turn in a complete circle:

360°/45°=8

it would take 8 45° angles to turn in a complete circle

Answer:

Rational

Answer:

25.5 u²

Step-by-step explanation:

Find the area of the rectangle, then the area of the triangle. To get the final area, add them together.

Rectangle: 3 x 5 = 15

Triangle: 3 x 7 ÷ 2 = 10.5

Total: 15 + 10.5 = 25.5 u² (you put it in units since you don't know the measure, e.g. cm, m, km...)

Answer:

Step-by-step explanation:

2, -3 , -8 , -13 , - 18 .............

This is an arithmetic sequence.

First term = a = 2

Common difference = Second term - first term

                                 = -3 - 2 = -5

Nth term = a + (n - 1)*d

               = 2 + (n - 1)*(-5)

               = 2 + n*(-5) - 1 *(-5)

               = 2 - 5n + 5

             = 7 - 5n

n = 19,

19th term = 7 - 5*19

               = 7 - 95

               = - 88

n = 21,

21st term = 7 - 5*21

               = 7 - 105

               = -98

Step-by-step explanation:

One number = 3x

Another = 5x = 30

5x= 30

x = 30 / 5 = 6
