Answer:

3/4 × 2/5 = 3/10

Step-by-step explanation:

3/4 × 2/5 is equivalent to 3/4 of 2/5

First, you have to divide the number line in 5 parts, and locate 2/5 (see figure attached)

Next, you have to divide in 4 parts the segment that represents 2/5, and locate 3/4 of 2/5

If you continue dividing the whole line with the previous segment length, you will divide the whole line into 10 parts.

Then, 3/4 of 2/5 is 3/10.

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°

Effectus [21]

Answer:

m∠A = 50°

m∠B = 70°

m∠C = 60°

Step-by-step explanation:

Determine the measure of angle A, B, and C in triangle ABC. If m∠A=(x-10)°,m∠B=(2x-50)°,and m∠C=x°

In a Triangle, the sum of the interior angles of a triangle = 180°

Step 1

We solve for x

Hence:

m∠A + m∠B + m∠C= 180°

(x-10)°+ (2x-50)°+ x° = 180°

x - 10 + 2x - 50 + x = 180°

4x - 60 = 180°

4x = 180° + 60°

4x = 240°

x = 240°/4

x = 60°

Step 2

Solving for each measure

x = 60°

m∠A=(x-10)°

= 60° - 10°

= 50°

m∠B=(2x-50)°

= 2(60)° - 50°

= 120° - 50°

= 70°

m∠C=x°

= 60°

Given:

The expression is

$\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=$

To find:

The simplified form of the expression.

Solution:

We have,

$\sqrt[3]{48}=\sqrt[3]{8\cdot \_\_}=$

The expression $\sqrt[3]{48}$ can be written as

$\sqrt[3]{48}=\sqrt[3]{8\cdot 6}$

$\sqrt[3]{48}=\sqrt[3]{8}\cdot \sqrt[3]{6}$ $[\because \sqrt[3]{ab}=\sqrt[3]{a}\sqrt[3]{b}]$

$\sqrt[3]{48}=2\cdot \sqrt[3]{6}$

$\sqrt[3]{48}=2\sqrt[3]{6}$

Therefore, $\sqrt[3]{48}=\sqrt[3]{8\cdot 6}=2\sqrt[3]{6}$ .

Question : 3/4+ 0.6 = ? 1.15 1.35 1.45 or 1.05

Artyom0805 [142]

we have

$\frac{3}{4} +0.6$

we know that

$\frac{3}{4}=0.75$

and

$0.75=0.40+0.35$

substitute in the expression

$0.40+0.35 +0.6$

$(0.40+0.60)+0.35$

$(1.00)+0.35=1.35$

therefore

<u>the answer is</u>

$1.35$
