Step-by-step explanation:

Answer:

1, 4 or 7

Step-by-step explanation:

The divisibility rule/shortcut for 3 is that the sum of its digits is divisible by 3. So, you currently have 29 (7+1+7+6+2+6+0), and you have to make that number divisible by 3.

adding 1 gets you 30, which we know is divisible by 3.

then, instead of trying every digit, we can note that

30 , 33 , 36 , 39 ....

are divisible by 3.

But the most we can add to the sum of 29 is 9 (because that is the highest digit possible)--so numbers above 38 are irrelevant

so, we want to find out if we can make 29 into 30, 33, or 36

adding 1 to 29 = 30

adding 4 to 29 = 33

adding 7 to 29 = 36

So, by making the first digit 1 , 4 , or 7, you make the number divisible by 3 (making the sentence true)

Answer:

6 Kilometers.

Step-by-step explanation:

Try not to overthink these questions! They are easy if you just think of them in simple terms!

6 km * 3 h = 18 km

4 km * 3 h = 12 km

18 km - 12 km = 6 km.

Answer:

Equivalent to 8(t+8):

8t+64

(8*t)+(8*8)

Equivalent to 8t+8:

4t+8+4t

4(2t+2)

Equivalent to neither:

8t+16

(8+t)+(8+8)

Step-by-step explanation:

First we expand the bracket 8 (t + 8)

This gives us 8t + 64

Option 1:

8t + 16 is not an option, so it goes in the neither box.

Option 2:

8t + 64 is an option, so it goes in the 8 (t + 8) box.

Option 3:

(8 * t) + (8 * 8) is an option, so it goes in the 8 (t + 8) box.

Option 4:

4t + 8 + 4t is an option, so it goes in the 8t + 8 box.

Option 5:

4 (2t + 2) is an option, so it goes in the 8t + 8 box.

Option 6:

(8 * t) - (8 * 8) is not an option, so it goes in the neither box.

Answer:

158 in

Step-by-step explanation:

front/back faces: 8 * 3 = 24in

side faces: 8 * 5 = 40in

top/bottom faces: 3 * 5 = 15in

2 * (24 + 40 + 15) = 158in

Answer: A

Step-by-step explanation:

This type of question is compound probability and it involves independent variables because the outcome of 1 event doesn't impact the probability of the next one.

the probability of taking an orange bulb is 7/22. Since he put that bulb back in the box, the probability of taking an orange bulb again, doesn't change. So the "compound probability " is 7/22x7/22= 49/484.

Answer: . Area of figure = area of squane + anea

of tringle =side * side + 1/2 xbagex height =7 * 7+

1/2 * 7 *

Approximately 8.47 cm² of the figure is painted green

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

To find the area painted green, we need to calculate the areas of the square and the triangle and then multiply by 14.2% (or 0.142).

The area of the square is simply the length of one side squared, so:

Area of square = (7 cm)² = 49 cm²

The area of the triangle is one-half the base times the height, so:

Area of triangle = (1/2)(7 cm)(3 cm) = 10.5 cm²

Therefore, the total area of the figure is the sum of the area of the square and the triangle:

Total area = 49 cm² + 10.5 cm² = 59.5 cm²

Finally, to find the area painted green, we multiply the total area by 14.2%:

Area painted green = 0.142 x 59.5 cm² ≈ 8.47 cm²

Therefore,

Approximately 8.47 cm² of the figure is painted green

Answer:

A. 20.86 square inches

Step-by-step explanation:

a)

We know that the formula for the area of a rectangle is Length x Height (A = LH).

Length (L) = 6 inches

Height (H) = 4 inches

So we incorporate our formula for the area of a rectangle into this situation:

Area (A) = 6 x 4

Area (A) = 24 in^2

b)

We know that the formula for the area of a circle is Pi x radius squared (A = πr^2).

Radius (r) = 1 inch

So we incorporate our formula for the area of a circle into this situation:

Area (A) = 3.14 x 1^2

Area (A) = 3.14 in^2

c)

We can see from the diagram that the shaded region come mainly from the rectangle.  So to find the area of the shaded part, we can simply subtract the area of the circle, from the area of the rectangle (Area of rectangle - Area of circle = Area of shaded region).

Area of rectangle = 24 in^2

Area of circle = 3.14 in^2

So we incorporate our formula for the area of the shaded part into this situation:

Area (A) = 24 in^2 - 3.14 in^2

Area (A) = 20.86 in^2

A

The probability that the store manager selects 2 comedies and 1 action movie is 96/3375.

Given that,

A video rental store keeps a list of its top 15 movie rentals each week.

Total = 15

Action movies = 6

Comedies = 4

When she selected three movies,

Probability of selecting an action movie = 6/15

Probability of selecting a comedy movie = 4/15

Probability of selecting one action and 2 comedies = 6/15 × (4/15)²

                                                                                      = 96/3375

Hence the required probability is 96/3375.
