Answers
Answer:
x=54 degrees
Step-by-step explanation:
These two angles are complementary, meaning that they add to 90 degrees.
If one angle is 36 degrees, then we can write this equation: 36+x=90
We want to find what x is, so we should isolate x.
We can isolate x by subtracting 36 on both sides.
x=90-36
x=54
Answer:
54°
Step-by-step explanation:
∠PQR +∠RQS =∠PQS
36° + x° = 90°
x = 90 - 36 = 54°

Solve the equation r = 1/(x-1) for x in terms of r. In other words, manipulate the equation until you have x equal to an expression with r's in it but no x's.
Answers
Answer:
\(x=\frac{1}{r} +1\)
Step-by-step explanation:
\(r=\frac{1}{x-1}\)
\(r(x-1)=1\)
\(x-1=\frac{1}{r}\)
\(x=\frac{1}{r} +1\)
Answer:
\(x=\dfrac{1+r}{r}\)
Step-by-step explanation:
Given equation:
\(r=\dfrac{1}{(x-1)}\)
Multiply both sides by (x - 1):
\(\implies r(x-1)=\dfrac{1}{(x-1)} \cdot (x-1)\)
\(\implies r(x-1)=1\)
Expand the brackets:
\(\implies rx-r=1\)
Add r to both sides:
\(\implies rx-r+r=1+r\)
\(\implies rx=1+r\)
Divide both sides by r:
\(\implies \dfrac{rx}{r}=\dfrac{1+r}{r}\)
\(\implies x=\dfrac{1+r}{r}\)
The length of a building is 60 feet. The length of the building on a scale drawing is 4 inches. Which ratio describes the scale of the drawing?
-- giving brainliest to whoever has the answer (with descriptions and such)
-- if no one else answers (but only one person), i'll be able to give five stars and a thanks
Answers
the ratio of the scale drawing is
1 inch on the drawing represents 180 feet in real life.
To determine the ratio of the scale drawing, we need to first find the length of the building on the scale drawing. We know that the actual length of the building is 60 feet, and the length of the building on the scale drawing is 4 inches. We can set up a proportion to find the length of the building on the scale drawing:
Actual length / Length on scale drawing = Scale factor
We can plug in the values we know:
60 feet / Length on scale drawing in inches = Scale factor
To solve for the length on the scale drawing in inches, we can cross-multiply:
60 feet * 1 inch / Scale factor = Length on scale drawing in inches
Simplifying:
Length on scale drawing in inches = 60 feet * 12 inches / Scale factor
We know that the length on the scale drawing is 4 inches, so we can plug that into the equation:
4 inches = 60 feet * 12 inches / Scale factor
Solving for the scale factor:
Scale factor = 60 feet * 12 inches / 4 inches
Scale factor = 180
Kevin's weekly salary is 865. He receives a 25% raise. How can Kevin find his new weekly salary? Select all that apply.
a. divide 865 by 0.25
b. divide 865 by 1.25
c. multiply 865 by 0.25
d. multiply 865 by 1.25
e. add 865 and 1/4 of 865
f. add 865 and 1 1/4 of 865
Answers
Answer:
Option d. (also option e depending on which way you want to calculate it)
Step-by-step explanation:
First, I should point out that percentage basically means 'out of one hundred' so 25% means '25 out of one hundred.' The value of the percentage increase = 25% × 865. The new value = 865 + The value of the percentage increase.
______________________________________
More Simple Explanation:
Alright, so this might not be a super 'mathematical' trick or related to this question but it still works. Basically we just have to convert 25% into a decimal which I do by moving the decimal point 2 numbers to the left. (Since we cannot see the decimal point in the percentage we automatically know that it stays at the end of 25 a.k.a 25.0) So now our number becomes 0.25 (we got rid of the percentage symbol). Now we just multiply 865 by 0.25 to get our answer!
______________________________________
More Mathematical Process *Basically the value and random useless stuff to know lol because my math teacher showed me this and I thought I needed to add this*:
1) Calculate the new value of the number increased by percentage of its initial value
The new value =
865 + The value of the percentage increase =
865 + (25% × 865) =
865 + 25% × 865 =
(1 + 25%) × 865 =
(100% + 25%) × 865 =
125% × 865 =
125 ÷ 100 × 865 =
125 × 865 ÷ 100 =
108,125 ÷ 100 =
1,081.25
2) Calculate the actual change (the difference) between the new value and the initial one
The actual change =
The new value - 865 =
1,081.25 - 865 =
216.25
(For positive numbers, the actual change = The value of the percentage increase)

\(\frac{14}{3} /\frac{2}{3}\) (changed to an improper fraction)
Whenever dividing fractions, remember this:
SAME, CHANGE, RECIPROCAL (FLIP)
KEEP THE FIRST FRACTION THE SAME
CHANGE THE DIVISION SIGN TO A MULTIPLICATION SIGN
FLIP THE SECOND FRACTION
\(\frac{14}{3} *\frac{3}{2} =\frac{42}{6}\)
\(\frac{42}{6} =7\)
I, therefore, believe Muna will have 7 pieces of string.

Which type of reaction is NaCl + AgNO3 → NaNO3 + AgCl?
A. synthesis
B. decomposition
C. oxidation
D. replacement
Answers
Step-by-step explanation:
The reaction NaCL + AgNO3 → NaNO3 + AgCL is a replacement reaction.
The given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.
When elements swap positions in compounds, a replacement reaction takes place. Ions are involved in this kind of response. In most cases, more reactive elements take the place of less reactive ones. When one element replaces another in a compound, it is known as a single replacement reaction.
Here,
In the given chemical reaction, Na is replaced by Ag, As per the above definition of the replacement reaction.
NaCl + AgNO3 = Na- cl + Ag-NO3 → NaNO3 + AgCl
Thus, the given chemical reaction NaCl + AgNO3 → NaNO3 + AgCl is a replacement reaction. Option D is correct.

Step 1: Divide the decimal number by the base (8) and obtain the quotient and remainder.Step 2: Write down the remainder.Step 3: Repeat the process with the quotient obtained in the previous step until the quotient is zero.Step 4: Write down the remainders in reverse order.Let's perform these steps for the decimal number 310:
310 ÷ 8 = 38 (remainder 6)38 ÷ 8 = 4 (remainder 6)4 ÷ 8 = 0 (remainder 4)Now, write down the remainders in reverse order: 466.
So, the decimal number 310 converted to base 8 is \(466_8\).
