Using the simple interest relation, the amount invested in stocks and bond respectively is $15,000 and $2000

Simple interest

Let her total principal = p

Stock :

Bond :

Total interest earned :

1050 + 0.09p - 1350 = 1230

-300 + 0.09p = 1230

0.09p = 1230 + 300

0.09p = 1530

p = $17000

Hence,

Amount invested in stock at 7% = $15000

Amount invested in bond at 9% = $17000 - 15000 = $2000

Answer:

c. 138 feet

Step-by-step explanation:

h(t) = −16t^2 + 83t + 33

At3 seconds

h(3) = -16(3^2) + 83(3) + 33

h(3) = -16(9) + 249 + 33

h(3) = -144 + 249 + 33

h(3) = 138

c. 138 feet

Answer:N(5)=1.5

Step-by-step explanation:The independent variable x represents the Number of hours driven and the dependent variable is the gallons of gas remaining, because the gallons of gas remaining depends on the number of hours driven.

A function relating these variables is Nx=14-2.5

So N(5)=1.5 meaning 5 hours of driving will result in 1.5 gallons left in the tank.

Answer:

75

Step-by-step explanation:

First, we know that 60 is 80 percent of something.

So, on that knowledge, we can setup this equation:

X × 0.80 = 60

Then, we multiply both sides by 0.80 , we then get 75.

We can check with 75 × 0.80 does equal to 60!

Answer:

x = 68°, y=14

Step-by-step explanation:

∵ m║n

∴ m∠x = 180 - m∠112

m∠x = 68°

∵ ∠x and ∠(5y - 2) are vertically oppose

∴ m∠(5y - 2) = m∠x

m∠(5y - 2) = 68

Make equation

5y - 2 = 68

5y = 68 + 2

5y = 70

y = 70/5

y = 14

Hope this helps

Step-by-step explanation:

• The supplement of the angle with the measure of 112° is :

[tex]\bf x + 112 = 180 \\ \bf x = 180 - 112 \\ \bf \boxed{ \color{#FF0000}x = 68 }[/tex]

This angle of 68° and the angle sign x° are in angular positions.

Internal alternators

The lines m and n are parallel, these angles have the same measure.

The marking of the angle x and the marking of the angle (5y-2)° are opposite to the vertex.

They have the same measure:

[tex]\bf 5y - 2 = 68 \\ \bf 5y = 68 + 2 \\ \bf 5y = 70 \\ \bf y = 70 \div 5 \\ \bf \boxed{ \color{#FF0000}y = 14 }[/tex]

Answer:

$154.52

Step-by-step explanation:

First, you need to know the formula for this type of question.

The formula is I = Prt. These variables are: I = Interest, P = Principle investment, r = Rate, and t = Time.

So, your equation is I = 572.30(0.045)(6), where you have to find "I".

If you multiply 0.045 and 6, you get 0.27. Then, you multiply 0.27 and 572.30, which is 154.521.

The interest you earn will be $154.521. You can round the thousandths digit based on how you have been taught to do, but I will round the answer to 154.52.

Good luck!

Answer:

[tex]\frac{1}{3} *\frac{1}{2} =\frac{1}{6}[/tex]

Step-by-step explanation:

So the first two balls are black, so the way to change the path is to take two out of six black balls over two out of ten balls, which is 1/3.

If the last one is red then the probability is that if you take one of the four red balls and you take one of the eight balls, you get 1/2.

So the total probability is 1/3 times 1/2 is 1/6.
