Answer:

B

Step-by-step explanation:

2-1/2 x 1 x 1/2 = 1-1/4

Answer:

C

Step-by-step explanation:

Multiply 1, 1 1/2, and 1/2 to get your volume

= 1 1/4

Then multiply 1 1/4 by 8 to get your half units

=10

7) A regular quadrilateral is a square, so any angle on a square is 90°, A

8) Looking at the shape, it appears to be B (4 sides and symmetrical)

9) The shape appears to be B (4 sides, opposite angles are equal, all sides are equal)

I forgot the formula for a trapezoid, but I'm sure you use it or their properties to find the rest.

Answer: 45 liters

Step-by-step explanation:

If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.

15 / 2 = 7.5.

Roger can jar 7.5 liters of jam every day.

Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.

7.5 x 6 = 45.

Therefore, Roger can jar 45 liters of jam in 6 days.

Answer:

There are 76 students:

g + b = 76

girls is 13 more than twice the boys:

g = 2b + 13

replace g with 2b + 13 in 1st equation

2b+13+b = 76

3b + 13 = 76

3b = 63

b = 21 boys

g = 76-21 = 55 girls

Step-by-step explanation:

Answer:

Q2)

We have food for 400 people, and it will last for 23 days.

Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:

23 days = K/400 people.

Then we get:

(23 days)*(400 people) = K = 9200 days*people.

Now if we increase the number of people by 60, we get.

people = 460

Then the number of days that this will last is:

D = (9200 days*people)/460 people = 20 days.

The food will last for 20 days.

Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:

40 = k*200

With this, we can find the value of k

40/200 = k = 0.2

Then the proportional relationship is:

y = 0.2*x

a) We need to replace x by 15.

y = 0.2*15 = 3

y = 3

b) We need to replace y by 8.

8 = 0.2*x

8/0.2 = x = 40

x = 40

Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.

Then we get:

8 = k/30

Then the value of k is:

8*30 = k = 240

then the relationship is:

y = 240/x

a) we need to replace x by 4

y = 240/4 = 60

y = 60

b) we need to replace y by 360

360 = 240/x

360*x = 240

x = 240/360 = 0.666...

x = 0.666...

8 + g = 15

g = 15 - 8

(3x + 6)° = 48°

4x° = 56°

(2x + 6)° = 34°

Step-by-step explanation:

Given is the figure of a kite.

In a kite, diagonals intersects each other at right angles.

Therefore,

[tex](2x + 6) \degree + 4x \degree + 90 \degree = 180 \degree \\ \\ (2x + 6 + 4x) \degree = 180 \degree - 90 \degree \\ \\ (6x + 6) \degree = 90 \degree \\ \\ 6x + 6 = 90 \\ \\ 6x = 90 - 6 \\ \\ 6x = 84 \\ \\ x = \frac{84}{6} \\ \\ x = 14 \\ \\ (3x + 6) \degree = (3 \times 14 + 6) \degree = 48 \degree \\ \\ 4x\degree = 4 \times 14 \degree= 56 \degree \\ \\ (2x + 6) \degree = (2 \times 14 + 6) \degree = 34\degree[/tex]

Solution 1.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 4 appeared = 8

Probability

= No. of preferred outcomes/Total number of outcomes

= 8/80

= 1/10

= 0.1

Solution 2.

Number of times the dice is rolled

= 11 + 22 + 7 + 8 + 13 + 19

= 80

Number of time 2 appeared = 22

Probability

= No. of preferred outcomes/Total number of outcomes

= 22/80

= 11/40

= 0.275
