Answer: 42

Step-by-step explanation: Break each number down using multiplication

Answer:

B. 19

Step-by-step explanation:

To find the combined amount, you have 1.5 + 3.25, since it asks for the time a scientist uses to observe both the dolphins and sea lions.

So we have 4.75 every 2 days, and it asks us for the amount in 8 days.

4.75 x 4 = 19

Answer:

35 m²

Step-by-step explanation:

Given:

⇒ length of hedge = (1.2 ÷ 2) x 11 = 6.6 m

Given:

⇒ length of pond = 2 x 4 = 8m

Given:

⇒ width of pond = 28 ÷ 8 = 3.5 m

⇒ perimeter of pond = 2 x 8 + 2 x 3.5 = 23 m

Given:

⇒ length of flowerbed = 8 + 2 = 10 m

Given:

⇒ width of flowerbed = [23 - (2 x 10) ] ÷ 2 = 1.5 m

Area of grass = (length of gate x width of pond) + (length of flowerbed x [length of hedge + length of compost heap - width of flowerbed - width of pond])

= (2 x 3.5) + (10 x [6.6 + 1.2 - 1.5 - 3.5])

= 7 + (10 x 2.8)

= 35 m²

The sampling method which is least likely to include sampling bias is: A. A random sample of 500 adults in the state.

A sampling bias can be defined as a type of bias in which members of an intended population are selected in such a way that some members have a higher or lower sampling probability than the other members.

This ultimately implies that, a sampling bias occur when members of an intended population are selected incorrectly and as such resulting in a sample that is not representative of the entire population.

In conclusion, a random sample of 500 adults in the state is least likely to include sampling bias.

Answer:

The length of the rectangle is 30 cm, and the width of the rectangle is 18 cm.

Step-by-step explanation:

Since the wire is shaped as a rectangle, and we need perimeter for this problem, we can use the equation (l+w)*2, and the perimeter is 96, where l is the length and w is the width.

Since the length is 12 cm longer than the width, then we have:

W + 12 = L

Now substitute for the L in our equation and solve.

(w+12+w)*2 = 96

(2w + 12) *2 = 96

Multiply using the distributive property

4w + 24 = 96

4w = 72

w = 18

Now plug in the w for our second equation:

18 + 12 = L

30 = L

Now check our answer by plugging it in our old equation:

(18+30)*2 = 96

48*2 = 96

96 = 96

Our answer is correct, so the length of the rectangle is 30 cm, and the width of the rectangle is 18 cm. Hope this helps.

[tex]8x - 1 < 15 \\ 8x < 15 + 1 \\ 8x < 16 \\ x < \frac{16}{8} \\ x < 2[/tex]

Answer:

As Per Given Information

The given equation is 8x-1 <15

Adding both side 1 we obtain

↝ 8x - 1 + 1 < 15 + 1

↝ 8x < 16

Now dividing both side by 8 we obtain

↝ x < 2

So, the required answer is x < 2.

Answer:

you need to do a step by step explanation.

Here we have some problems about circles, the solutions are:

We know that for a circle of diameter D, the area is given by:

A = pi*(D/2)^2

where pi = 3.14

In the image we can see that the diameter of the circle is 25 yd, replacing that in the area equation we get:

A = 3.14*(25yd/2)^2 = 490.6 yd^2

For the second image, each line creates two 180° angles. So, if we look at the tilted line, we can see that it is divided in two angles, one of 37° and the other that depends of x, so we can write:

180° = 37° + (9x + 8)°

180° - 37° - 8°  = (9x)°

135°/9° = x = 15

So the value of x is 15.

For the last image:

Notice that we have a 90° angle denoted, then the other 3 sections must add up to 270°.

270° = 54° + (2x + 21)° + (5x + 6)°

Now we solve this for x:

270 - 54 - 21 - 6 = 2x + 5x

189 = 7x

189/7 = x = 27

x is equal to 27

Answer:

18

Step-by-step explanation:

Since f '(x) ≥ 3, that means for every x, it can increase by 3 or greater. If we want to find the smallest f(5), we have to use the smallest rate of change possible, which is just 3.

Then, we have to find how many times x changes. Since we are going from 3 to 5, that means x changes 2 times. (5 - 3 = 2)

Now we multiply the rate of change (3) by the number of x changes.

3 x 2 = 6

We then add that to 12 since that is the number we started with

12 + 6 = 18
