I found a graph with the same problem, so I guess this is the graph to be based on. To find the rate, just determine the slope between any two points along the line. Suppose these points are: (30,10) and (50,20).

Slope = (20 - 10)/(50 - 30) = 1/2

<em>The correct answer should be: the rate of change is 1 cm per 2 weeks, or 1/2.</em>

Maria invested $4,000 at 3.5% simple interest. She left the principal invested for 57 months. Robert invested $3,500 at 8.5% sim
Alex_Xolod [135]

Answer:

Maria have $123,75 more total money than Robert at the end of their investments.

Step-by-step explanation:

To calculate the simple interest we should multiply the Initial invest, with the interest without percentage and the time in years.

As the time is in months we have to divide it by 12 so we have the mesure of time in years, then the interest for each of the investments will be:

Maria

Invest = $4,000 Interest = 3.5/100=0.035  Time = 57/12 = 4.75

Simple Interest = 4,000 x 0.035 x 4.75 = $665

Total money at the end of the invest = $4,000 + $665 = $4,665

Robert

Invest = $3,500 Interest = 8.5/100=0.085  Time = 42/12 = 3.5

Simple Interest = 3,500 x 0.085 x 3.5 = $1,041.25

Total money at the end of the invest = $3,500 + $1,041.25 = $4,541.25

Now we have to subtract the total money of Robert from the total money of Maria to know how much money did she got over Robert after their invests

$4,665 - $4,541.25 = $123.75

At the end of the invest, Maria got $123,75 more than Robert

Justin is using the figure shown below to prove Pythagorean Theorem using triangle similarity: In the given triangle ABC, angle
Natali [406]

Option fourth "By the addition property of equality, AC² plus AB² = BC multiplied by DC plus AB² is correct.

<h3>What is the Pythagoras theorem?</h3>

The square of the hypotenuse in a right-angled triangle is equal to the sum of the squares of the other two sides.

The figure is missing.

The right-angle triangle is shown in the picture; please refer to the picture.

The missing options are attached; please refer to the picture.

We have a right-angle triangle shown in the picture.

The larger triangle ABC is similar to the smaller triangles as follows.

ΔABC ~ ΔDBA     (By AA similarity)

ΔABC ~ ΔDAC   (By AA similarity)

From the above similarity:

AC² or AB²

\rm \dfrac{AB}{BD} = \dfrac{BC}{AB}

After cross multiplication:

AB² = BC×BD

Now,

\rm \dfrac{AC}{CD} = \dfrac{BC}{AC}

AC² = BC×BD

AB² + AC² =  BC×BD + BC×BD

AB² + AC² =  2BC×BD

Thus, the option fourth "By the addition property of equality, AC² plus AB² = BC multiplied by DC plus AB² is correct.

Convert 185 degrees Celsius to degrees Fahrenheit. Round<br> your answer to the nearest degree
lakkis [162]

Hello! :3

Answer:

The Correct Answer is <u><em>365 °F</em></u>

Step-by-step explanation:

The C to F formula is(C ~x~ 9/5) + 32 = F

When we do 185 for C in the formula, we get(185 ~x~ 9/5) + 32 = F.

To solve,  (185 ~x~ 9/5) + 32 = F. we first multiply 9 by 185, then we divide the product by 5, and then finally we add 32 to the quotient to get the answer.

185~x~9=1665

1665  /5=333

333+32=355

Therefore, the answer to 185 C to F is 365 which can be written like this

⇒ 185 °C = 365 °F

hope this helps you!

Have an Awesome Thursday!
