The total interest on a 5-year 5.2% loan with a principal of $10,000 is $2600. The calculation is true.

Simple interest is a quick and easy way to calculate a loan's interest charge. Simply multiplying the daily interest rate by the principal by the number of days between payments yields simple interest.

Given that the amount of $10000 is deposited at the interest rate of 5.2% for the 5 years.

The simple interest is calculated by the formula written below,

SI = ( P x R x T ) / 100

SI = ( 10000 x 5.2 x 5 ) /100

SI = $2600

Step-by-step explanation:

Answer:

0

Step-by-step explanation:

(NegativeA) + (PositiveA) = 0

Note for future reference:

(NegativeA) + (PositiveB) = (NegativeC)

(PositiveA) + (NegativeB) = (NegativeC)

(NegativeA) + (NegativeB) = (NegativeC)

(PositiveA) + (PositiveB) = (PositiveC)

Answer:

The formula for an exponential decay problem is: y = x (1 - r)^x

Where x = initial amount, r = rate of decay and x = # time periods

So, x = $258, r = 8% = .08 and x = 11 years

y = 258 (1 - 0.08)^11 = 258 (0.92)^11 = 258 * 0.3996 = $103.10

Answer: 16.75 milliliters

Step-by-step explanation:

I believe it is 16.75 because 0.35 + 16.4 is 16.75 why is it addition decimals? Because it says How many milliliters does the mixture contain. It is talking about both combined, I hope this helps you if not sorry this was rushed! I am also 3rd Grade this Year! :D

The total mixture is 16.75 ml

Mixture is a combination of two or more elements to form a third element.

Given here, Jada mixes 0.35 ml to 16.4 ml milk and therefore the total mixture is equal to 0.35 + 16.4 = 16.75 ml

Hence Jada's mixture contains 16.75 ml

The values of P and Q are 270 units and 367 units respectively.

In a right-angled triangle, the sum of the squares of the smaller two sides of a right-angle triangle is equal to the square of the largest side.

We know, From Pythagoras's theorem hypotenuse² = base² + height².

So, p² = 179² + 203².

p = [tex]\sqrt{179^2 + 203^2[/tex].

p = [tex]\sqrt{32041 + 41209[/tex].

p = [tex]\sqrt{73250[/tex].

p = 270.

Now, we can find q.

q = [tex]\sqrt{250^2 + 270^2[/tex].

q = [tex]\sqrt{62500 + 72900[/tex].

q = [tex]\sqrt{135400[/tex].

q = 367.

Step-by-step explanation:

Answer:

88.85 Sq m

Step-by-step explanation:

For rectangle:

Length = 18 - 7.8 = 10.2 m

Width = 7.8 m

For both semicircular arcs:

Radius (r) = 7.8/2 = 3.9 m

Area of the shaded region = Area of rectangle + 2*Area of a semicircle - Area of circle with radius 3.5 m

[tex] = lb + 2 \times \frac{1}{2} \pi \times {(3.9)}^{2} - \pi \times {(3.5)}^{2} \\ \\ = 10.2 \times 7.8 + \pi \{{(3.9)}^{2} - (3.5)^{2} \} \\ \\ = 79.56 + \pi {(3.9 + 3.5)} (3.9 - 3.5) \\ \\ = 79.56 + 3.14 \times 7.4 \times 0.4 \\ \\ = 79.56 + 9.2944 \\ \\ = 88.8544 \\ \\ \approx 88.85 \: {m}^{2} [/tex]
