Answer:

a = 9h + nb

Step-by-step explanation:

Eli works in an electronics repair shop.

He earns per hour = $9.00

and a bonus amount for each items he repairs.

If a = total

h = hours worked one week

n = number of items

b = bonus amount

The formula that will help Eli to determine how much money he will earn in one week is

a = 9h + nb

Given: △ABC, AB=5 sqrt 2 m∠A=45°, m∠C=30° Find: BC and AC will give brainliest!!! By the way the answer is not 5 and 3.66

Makovka662 [10]

Answer:

Therefore,

$BC=a=10\ units\\\\AC=b=13.66\ units$

Step-by-step explanation:

Consider a Δ ABC with

m∠ A = 45°

m∠ C = 30°

AB = c = 5√2

To Find:

BC = a = ?

AC = c = ?

Solution:

Triangle sum property:

In a Triangle sum of the measures of all the angles of a triangle is 180°.

$\angle A+\angle B+\angle C=180\\\\45+30+\angle B=180\\\ttherefore m\angle B =180-75=105\°$

We know in a Triangle Sine Rule Says that,

In Δ ABC,

$\frac{a}{\sin A}= \frac{b}{\sin B}= \frac{c}{\sin C}$

substituting the given values we get

$\frac{a}{\sin 45}= \frac{b}{\sin 105}= \frac{5\sqrt{2} }{\sin 30}$

∴ $\frac{a}{\sin 45}= \frac{5\sqrt{2} }{\sin 30}\\\\a=\sin 45\times \frac{5\sqrt{2} }{\sin 30}\\\\a=\frac{1}{\sqrt{2} }\times \frac{5\sqrt{2} }{0.5} \\\\\\a=\frac{5}{0.5} =10\\\therefore BC = a = 10\ units$

Similarly for 'b',

$\frac{b}{\sin 105}= \frac{5\sqrt{2} }{\sin 30}\\\frac{b}{0.9659}= \frac{5\sqrt{2} }{0.5}\\\\b=0.9659\times \frac{5\sqrt{2} }{0.5}\\\\b=\frac{6.8301}{0.5} \\\\b=13.66\\\therefore AC = b =13.66\ units\\$

Therefore,

$BC=a=10\ units\\\\AC=b=13.66\ units$

two decimal numbers have digits to the thousands place if you multiply them how many digits do you expect there to be after the

disa [49]

There will be 6 decimal digits in the product of the numbers and can be fewer than 6.

<h3>What are decimal numbers?</h3>

A decimal number has a whole number and a fractional part.

Given that the two decimal numbers have digits to the thousandth place.

Therefore, there are three digits after the decimal point.

The number of digits after the decimal point in the product of two decimal numbers is the sum of the digits after the decimal point in both numbers.

Let the first number be 0.001 and the second number be 0.002.

Then, the number of decimal digits in the product of 0.001 and 0.002 will be 6.

If the two numbers are 0.005 and 0.002, then surely, there will be less than 6 digits after the decimal as the last 0 can be omitted in counting.

Hence, there will be 6 decimal digits in the product of the numbers and can be fewer than 6.

Ms. Lou rolls out 2 3/5 ft. of dough. If she cuts the dough into sections that are 1/4 of a ft. each, how many sections of dough

Natasha_Volkova [10]

Answer:

Step-by-step explanation:

We need to divide 2 3/5 ft by 1/4 ft.

2 3/5 / 1/4 =

= 2 3/5 * 4

= 13/5 * 4

= 52/5

= 10 4/10
