Answer:

Step-by-step explanation:

Point B represents (-2) on the number line. As you can see, -3 is to the left of B, and I know that the farther you left you go on the number line, the lesser the volume. (Hope this helps)

Answer:

Step-by-step explanation:

(You told me to do this)

The -(-2) cancels out the -2, making it just a positive 2.

A carpenter constructed a rectangular sandbox with a capacity of 10 cubic feet. If the carpenter were to make a similar sandbox

jeka57 [31]

Answer:

(D)80 ft³

Step-by-step explanation:

The volume volume of the sandbox is = L × W × H

Where L = Length, W= width, H= Height.

A sandbox has the same shape as a cuboid.

A cuboid is a solid shape with rectangular base and sides. It has six rectangular faces if all sides are closed.

From the question,

LWH = 10ft³ ........................ (1).

If a similar sandbox twice as long, twice as wide and twice as high.

∴ L₍n₎= 2L, W₍n) =2W, H₍n₎ = 2H

Where L₍n₎, W₍n), H₍n₎ is the new Length, new Width and new Height of the similar sandbox.

∴L₍n₎ ×W₍n)× H₍n₎ = 2L × 2W × 2H

and Volume of the new sandbox = L₍n₎ ×W₍n)× H₍n₎

⇒Volume of the new sandbox = 2 × 2 ×2 ×L×W×H

Volume of the new sandbox = 8 × LWH....................(2)

In equation(1) LWH = 10ft³.

Substituting the value in equation(2)

∴Volume of the new(similar) sandbox= 8 × 10

=80ft³.

Therefore the capacity of the second sandbox in cubic feet is 80.

The answer is option (D).

Given: △EDN∼△LKI, DQ , KO are altitudes, DN=12, KI=4, DQ=KO+6. Find: QN and OI.

fgiga [73]

Answer:

QN = 3√7
OI = √7

Step-by-step explanation:

The ratio of corresponding sides DN and KI is 12 : 4 = 3 : 1. The same ratio applies to altitudes DQ and KO. Since the difference between these altitudes is 6 and the difference between their ratio units is 3-1 = 2, each ratio unit must stand for 6/2 = 3 units of linear measure. That is, ...

DQ = (3 units)·3 = 9 units

KO = (3 units)·1 = 3 units

Then the base lengths QN and OI can be found from the Pythagorean theorem:

KI² = KO² +OI²

4² = 3² +OI²

OI = √(16 -9)

OI = √7

QN = 3·OI = 3√7

Does anyone know what the inequality would be?

dsp73

Let x = number of batches.

So for every batch, you need 2 cups of flour, and you have 20 cups of flour. You cannot make a batch if you don't have the sufficient amount. So using our information, our inequality is $2x \leq 20$ . However, this can be further simplified.

For this inequality, divide both sides by 2, and <u>your inequality is $x\leq 10$ .</u> <u>In context, you can make up to 10 batches of cookies.</u>
