Montoya Construction needs to borrow $375,000 to build a road to install utilities in a small subdivision. It borrows the funds

MissTica

Step 1

Given;

$\begin{gathered} \text{Principal(p)= \$375000} \\ \text{First rate = 8\%=}\frac{8}{100}=0.08 \\ \text{Second rate = 20\%= }\frac{20}{100}=0.2 \\ \text{Time}=\frac{90}{365}=\frac{18}{73} \end{gathered}$

Required; To find the difference in interest between the two periods.

Step 2

State the formula for simple interest

$A=P(1+rt)$

Step 3

Find the interest when the rate is 8%

$\begin{gathered} A=375000(1+(0.08\times\frac{18}{73}) \\ A=375000(1+\frac{36}{1825}) \\ A=\text{\$}382397.26 \end{gathered}$

Therefore the interest is given as;

$A-P=382397.26-375000=\text{\$}7397.26$

Step 4

Find the interest in 1980 with a 20% rate

$\begin{gathered} A=375000(1+(0.2\times\frac{18}{73}) \\ A=\text{\$}393493.15 \end{gathered}$

The interest is given as;

$A-p=393493.15-375000=\text{\$}18493.15\text{ }$

Step 5

Find the difference in interest between the two rates.

$\text{\$}18493.15-\text{\$}7397.26=\text{\$}11095.89$

Hence, the difference in interest between the two rates = $11095.89

A company makes poppy lapel pins.

mezya [45]

Answer:

<h2>The required percentage is 65.45%.</h2>

Step-by-step explanation:

The total costing is $1000 \times 1.10 = 1100$

35% were given to the charity, hence 350 were given to the charity.

There are (1000 - 350) = 650 lapel pins remaining.

60% of 650 = $\frac{60}{100} \times 650 = 390$ werre sold for 3.00 each. Hence, earning from here is $390 \times3 = 1170$ .

40% of 650 = 260 were sold at 5.00 for 2. It can also be said that $\frac{260}{2} = 130$ were sold at 5.00 each. Earning from this section is $130 \times5 = 650$

Total earning is (1170 + 650) = 1820.

Profit percentage = $\frac{1820 - 1100}{1100} \times100 = \frac{720}{11} = 65.45$

gtnhenbr [62]

Answer:

83°

Step-by-step explanation:

Since angle x and angle y are supplementary angles,

x + y = 180°.

Since y = 97°

x = 180° - y = 180° - 97° = 83°

LAST ONE!! (:

joja [24]

First you find how much the shape has dilated. To d ok that you divide the size of the size already given to you from the bigger shape from the same did if the smaller shape. So 58÷6=9.7. The shape grew by 9.7. To find x you use the similar side of the other shape again and multiy that size by 9.7. So 9.7×3=29.1

x=29.1
