Suppose it is x = the number

Suppose that h is the factor by which we want to multiply the number to double its square root.
So we have to:

√ (hx) = 2√x.

We solve the equation for us and that:

hx = 4x
h = 4.

You must multiply by 4 to duplicate the square root

Robert buys 4 pounds of cauliflower at $0.85 a pound. He also buys 4 pounds of brussels sprouts. If he spends $6.40 on the veget

postnew [5]

$0.85 * 4 = $3.40

$6.40 - $3.40 = $300

Brussel sprouts per pound = $300 / 4
= $0.75

Answer:

Option B is the right choice.

Step-by-step explanation:

Given:

An are CE and an inscribed angle CBE.

Measure of inscribed angle CBE = 25 °

We have to find the measure of the arc CE.

Concept:

An inscribed angle is an angle with its vertex on the circle.
The measure of an inscribed angle is half the measure the intercepted arc.
Measure of inscribed angle = 1/2 × measure of intercepted arc .

To find the measure of arc CE.

⇒ $\angle CBE = \frac{1}{2} \times m\ (arc\ CE)$

⇒ $2\times \angle CBE = m\ (arc\ CE)$

⇒ $2\times 25 = m\ (arc\ CE)$

⇒ $50 = m\ (arc\ CE)$

Measure of intercepted arc CE = 50 degrees.

The measure of arc CE = 50° so, option B is the right choice.

Find the annual rate of interest. Principal = 4600 rupees Period = 5 years Total amount = 6440 rupees Annual rate of interest =

Semmy [17]

Answer:

The rate of interest for compounded annually is 6.96 % .

Step-by-step explanation:

Given as :

The principal amount = Rs 4600

The time period = 5 years

The amount after 5 years = Rs 6440

Let The rate of interest = R %

<u>From compounded method</u>

Amount = Principal × $(1+\dfrac{\textrm rate}{100})^{\textrm Time}$

or, Rs 6440 = Rs 4600 × $(1+\dfrac{\textrm R}{100})^{\textrm 5}$

Or, $\frac{6440}{4600}$ = $(1+\dfrac{\textrm R}{100})^{\textrm 5}$

or, 1.4 = $(1+\dfrac{\textrm R}{100})^{\textrm 5}$

Or, $(1.4)^{\frac{1}{5}}$ = 1 + $\dfrac{R}{100}$

or, 1.0696 = 1 + $\dfrac{R}{100}$

or, $\dfrac{R}{100}$ = 1.0696 - 1

Or, $\dfrac{R}{100}$ = 0.0696

∴ R = 0.0696 × 100

I.e R = 6.96

Hence The rate of interest for compounded annually is 6.96 % . Answer
