The principal P is borrowed at a simple interest rate r for a period of time t. Find the simple interest owed for the use of the

Natasha_Volkova [10]

Answer:

= $20

Step-by-step explanation:

Simple interest is given by the formula'

Interest = PRt/100, where P is the principal amount, R is the rate of interest and t is the interest period in years

Therefore;

Simple interest = ($ 1000 × 2 × 1)/100

= $ 20

The simple interest owed for the use of the principal at a period of 1 year is $ 20.

Graph the system below and write its solution.

Diano4ka-milaya [45]

Answer:

See the graph attached. It has one solution: (6,-4)

Step-by-step explanation:

The slope-intercept form of a line is:

$y=mx+b$

Where m is the slope and b is the intersection of the line with the y-axis.

Given the first equation $y =\frac{-1}{2}x -1$

You can identify that:

b=-1

Substitute y=0 to find the intersection with the x-axis

$0 =\frac{-1}{2}x -1\\1(-2)=x\\x=-2$

This line passes through the points (0,-1) and (-2,0)

Given the second equation:

$-2 + y = -6$

Solve for y:

$y = -6+2\\y=-4$

It passes through the point (0,-4).

Now, you can graph. See the figure attached.

It has one solution,which is the point of intersection of both lines: (6,-4)

PLS HELP ME, PLS THIS IS DUE FIRST CORRECT ANSWER GETS BRAINLIEST

shusha [124]

Answer:

A. 49 + 16 (t - 1)

Step-by-step explanation:

Plug in t = 1 to test for the first hour:

$49+16(1-1)=49+16(0)=49$

Test as many values as you like, but testing t = 5:

$49+16(5-1)=49+16(4)=49+64=113$

You can see that plugging in just a few values confirms the answer.

Help due soon plss!!!!

Answer:

Cube=150cm^2

Triangular Prism=228ft^2

Step-by-step explanation:

Cube

$A=6a^2=6*5^2=150cm^2$

Triangular prism

Using these formulas

$A=2A_{B}+(a+b+c)h\\A_{B} =\sqrt{s(s*a)(s*b)(s*c)} \\s=\frac{a+b+c}{2}$

Solving for A

$A=ah+bh+ch+\frac{1}{2} \sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4} \\=6.5*11+5*11+6.5*11+\frac{1}{2} *\sqrt{-6.5^4+2*(6.5*5)^2+2*(6.5*6.5)^2-5^4+2*(5*6.5)^2-6.5^4} \\=228ft^2$
