SOMEONE PLEASE HELP!

Mathematics
1 answer:
Andrews [41]2 years ago
7 0

Answer:

17.2°

Explanations

To find angle A, use the cosine rule.

a^2 = b^2 + c^2 - 2 × a × c cos A

4^2 = 7^2 + 10^2 - 2 × 7 × 10 cos A

16 = 49+ 100 - 140 × cosA

16 = 149 - 140cosA

16- 149 = - 140cosA

-133 = - 140cosA

cosA = 133/140

cosA = 0.95

A = 17.2°

Point P(−5.15, −7.05) is a reflection across the x-axis of which of the following points?PLEASE EXPLAIN
Novay_Z [31]
The answer is A.
I only know how to explain by using the rule for reflection over x axis sorry.
The rule is (x,-y) x coordinate stays the same but you do the opposite for the y coordinate so -7.05 would be 7.05

1.4 divided by 72.8 work form please
Fittoniya [83]

$\frac{1.4}{72.8}$$

Multiply the numerator and denominator by: 10

\frac{14}{728}$$

Divide 14 by 728 to get 0

\begin{gathered}728 \frac{0 .}{14.0} \\\underline{0} \\1 \overline{4} 0\end{gathered}

Divide 140 by 728 to get 0

\begin{gathered}7 2 8 \longdiv { 1 4 . 0 0 } \\\underline{0} \\140 \\\underline{0} \\1400\end{gathered}

Divide 1400 by 728 to get 1

\begin{gathered}728 \frac{0.01}{14.000} \\\underline{0} \\1 \overline{4} 0 \\\underline{0} \\1400 \\\frac{728}{6720}\end{gathered}

Divide 6720 by 728 to get 9

\begin{gathered}728 \frac{0.019}{14.0000} \\\frac{0}{140} \\\frac{0}{1400} \\\frac{728}{6720} \\\frac{6552}{1680}\end{gathered}

Divide 1680 by 728 to get 2

\begin{aligned}&728 \frac{0.0192}{14.00000}\\&\frac{\underline{0}}{140}\\&{ }_{140} \frac{0}{0}\\&\frac{728}{6720}\\&\frac{6552}{1680}\\&\frac{1456}{2240}\end{aligned}

Divide 2240 by 728 to get 3

Stopping at 5 decimal places

The solution for Long Division of $\frac{1.4}{72.8}$ is $0.01923$

0.01923

Addition, subtraction, multiplication, and division are the four fundamental arithmetic operations in mathematics. The type of arithmetic operation has been selected based on the requirements of the task.

For instance, we must divide 100 by 25 to distribute 100 chocolates evenly among 25 youngsters.

Each youngster will thus get 4 chocolates. In this article, we'll go through one of the arithmetic operations called "Division or Divide," along with its symbol, division math formula, and several instances that have been solved.

Split, in its simplest form, is to divide into two or more equivalent portions, spaces, groups, or divisions. Split, in plain English, is to provide the entire item to a group in equal portions or to divide it into equal pieces. Let's say a square is divided into two triangles with equal areas by a diagonal. A division operation may or may not provide an integer as the outcome. The outcome may occasionally take the form of decimal numbers.
