Answer: To find the length of the missing side of a right triangle we can use the following trigonometric ratios.

Step-by-step explanation: Find the measure of each side indicated. Round to the nearest tenth. So, the measure of the missing side is 4.6. Find the measure of each side indicated. Round to the nearest tenth. Opposite side = AC = 10.8 So, the measure of the missing side is 13.

Homework: 5.1 Systems of Linear Equations

Klio2033 [76]

Answer:

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=8,\:y=5$

Step-by-step explanation:

Given the system of linear equations

$7x-y=51$

$x+3y=23$

solving by the elimination method

$\begin{bmatrix}7x-y=51\\ x+3y=23\end{bmatrix}$

$\mathrm{Multiply\:}x+3y=23\mathrm{\:by\:}7\:\mathrm{:}\:\quad \:7x+21y=161$

$\begin{bmatrix}7x-y=51\\ 7x+21y=161\end{bmatrix}$

$7x+21y=161$

$-$

$\underline{7x-y=51}$

$22y=110$

so

$\begin{bmatrix}7x-y=51\\ 22y=110\end{bmatrix}$

now solving for y

$22y=110$

$\mathrm{Divide\:both\:sides\:by\:}22$

$\frac{22y}{22}=\frac{110}{22}$

$y=5$

$\mathrm{For\:}7x-y=51\mathrm{\:plug\:in\:}y=5$

$7x-y=51$

$7x-5=5$

$7x=56$

$\mathrm{Divide\:both\:sides\:by\:}7$

$\frac{7x}{7}=\frac{56}{7}$

$x=8$

$\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}$

$x=8,\:y=5$

Question 5Ginny has $10,000 in a savings account earning 4% simple interest annually. Ginny plans on savingthis money for a long

Igoryamba

ANSWER

$18,000

EXPLANATION

Ginny has $10,000 in a savings account.

The interest is 4% simple interest.

We want to calculate Ginny's total account balance after 20 years.

To do this, we will first caluclate the interest and then we will add it to the initial balance.

To calculate Simple Interest, we use:

$\text{Simple Interest = }\frac{P\cdot\text{ R }\cdot\text{ T}}{100}$

P = principal = $10000

R = rate = 4%

T = time = 20 years

Therefore:

$SI\text{ = }\frac{10000\cdot\text{ 4 }\cdot\text{ 20}}{100}\text{ = \$8000}$

Therefore, her account balance after 20 years is:

Amount = $10000 + $8000 = $18,000
