What is the sum 2, 3, 4, and 5?

Answer:

The Answer is 8m square

Step-by-step explanation:

2m is the width

4m is the length

Answer:

52m²

Step-by-step explanation:

First since its only showing the front, top, and right side of the shape you count up all of the cubes you see.

Amount of cubes on each side:

Front: 6 cubes

Top: 8 cubes

Side: 12 cubes

6+8+12=26 cubes

But there is 6 sides total on the shape. Because we only did 3 sides, to get the final answer you multiply it by 2.

26×2=52

Final answer: 52m²

The computation of the quotation when Thando wants to build a garage will be $1700.

Your information is incomplete. An overview will be given based on the information. It should be noted that a quotation is given when one wants to construct a building.

Let's assume that the prices include:

Sand = $1000

Machinery work = $200

Building materials = $400

In this case, you simply have to add the values together.

= $1000 + $200 + $400

= $1700

Answer:

When selecting a sample for a survey, the way you choose your sample: A) may lead to biased results.

Step-by-step explanation:

The way you choose your sample matters a lot in order to help limit the bias in sampling data.

There are four types of random samples: simple, stratified, cluster, and systematic.

There are two types of non-random samples: voluntary response and convenience.

You always want to have a random sample in order to have accurate, non-biased results. Therefore, A) May lead to biased results is the best answer.

Answer:

44°

Step-by-step explanation:

180° - 68° = 112° (Angle 1)

The sum of the angles of a triangle is equal to 180°, so:

180° - 112° - 24° = 44°

Answer:

Below in bold.

Step-by-step explanation:

Total of 10 marbles in the bag.

a) Fraction that are green = 3/10.

b) Fraction that are purple = 7/10

= 100 * 7/10

= 90*7

=  70%

Since the price has been increasing by $7 per month, the rate at which revenue is changing when the price is $70 is $24500/month

To answer the question, we need to know what revenue is

This is the total price for the total amount of goods sold.

Revenue, R = px where

So, R = px

= p(77000 - 5p²)

= 77000p - 5p³

To find the rate at which the revenue is increasing with respect to price, we differentiate R with respect to p.

So, dR/dp = d(77000p - 5p³)/dp

= 77000dp/dp - 5dp³/dp

= 77000 - 15p²

Substituing p = 70 into dR/dp, we have

dR/dp = 77000 - 15p²

dR/dp = 77000 - 15(70)²

= 77000 - 15(4900)

= 77000 - 73500

= 3500

The rate at which the revenue is changing per month is

dR/dt = dR/dp × dp/dt where dp/dt = rate at which price is changing = $7 per month.

Now, dR/dt = dR/dp × dp/dt

So, dR/dt = 3500 × $ 7/month

dR/dt = $24500/month

So, the rate at which revenue is changing when the price is $70 is $24500/month

Step-by-step explanation:

I guess we only need to read the details of the already shown line (and don't need to calculate it from the scratch).

usually I am looking for points with integer coordinates to elaborate the equation.

I see here

(0, 2)

(3, 4)

(6, 6)

(9, 8)

the line equation is

y = ax + b

a being the slope, which is "y coordinate change / x coordinate change" when going from one point to another.

and b being the y-intercept (the y value when x = 0).

we know b already from the first point (0, 2) : b = 2.

so, for the slope we use e.g. the first 2 points

(0, 2) and (3, 4)

x changes by +3 (from 0 to 3).

y changes by +2 (from 2 to 4).

so, the slope is +2/+3 = 2/3

and the line equation is

y = 2/3 x + 2

or

y = 2x/3 + 2

Answer:

x = 6

Step-by-step explanation:

Interior angles of a triangle sum to 180°

⇒ (8x + 2)° + 70° + 60° = 180°

⇒ 8x + 132° = 180°

Subtract 132° from both sides:

⇒ 8x + 132° - 132° = 180° - 132°

⇒ 8x = 48°

Divide both sides by 8:

⇒ 8x ÷ 8 = 48° ÷ 8

⇒ x = 6

Therefore, the value of x is 6.

Answer:

V = 4 2/3 units ^3

Step-by-step explanation:

We are given the area of the back rectangle

V = BH where B is the area of the base

V = 3 1/3 * 1 2/5

Rewriting the mixed numbers as improper fractions

V = 10/3 * 7/5

V = 70/15

Simplifying

V = 14/3

Changing back to a mixed number

V = 4 2/3 units ^3
