Answer:
x ≥ 4
Step-by-step explanation:
Given the inequality 4x-1≥15
Add 1 to both sides
4x-1+1≥15+1
4x≥16
Divide both sides by 4
4x/4 ≥ 16/4
x ≥ 4
Hence the solution is x ≥ 4

hari purchased a camera for rs 1560 and sold ot at 5% loss. find hos loss amount
Answer:
[tex]SP = 1482[/tex]
Step-by-step explanation:
Given
[tex]CP = Rs. 1560[/tex] --- Cost Price
[tex]Loss = 5\%[/tex]
Required
Determine the selling price (SP)
This is calculated using:
[tex]\%Loss =\frac{CP - SP}{CP} * 100\%[/tex]
So, we have:
[tex]5\% = \frac{1560 - SP}{1560} * 100\%[/tex]
[tex]5 = \frac{1560 - SP}{1560} * 100[/tex]
Multiply through by 1560
[tex]1560 * 5 = \frac{1560 - SP}{1560} * 100*1560[/tex]
[tex]1560 * 5 = (1560 - SP) * 100[/tex]
[tex]1560 * 5 = 1560 * 100- SP * 100[/tex]
[tex]7800 = 156000- 100SP[/tex]
Collect Like Terms
[tex]100SP= 156000- 7800[/tex]
[tex]100SP= 148200[/tex]
Make SP the subject
[tex]SP = \frac{148200}{100}[/tex]
[tex]SP = 1482[/tex]
The selling price is Rs. 1482

Which angle must also measure 85°?
O 2
O 5
O11
0 12
Answer:
11
Step-by-step explanation:
11 has 85° because it is opposite to 9
The angle that must also be measured of 85° is angle 11.
Option C is the correct answer.
What is an angle?The angles between two lines are the angles formed by two intersecting lines, measured in degrees or radians.
Several different types of angles can be formed between two lines, including acute angles, right angles, and obtuse angles.
We have,
In the diagram,
∠9 = 85
This means,
∠9 and ∠11 are opposite angles.
And,
Opposite angles are equal.
So,
∠9 = ∠ 11 = 85
Thus,
The measure of angle 11 is also 90.

4: D) 12
7: C) 63
8: A) Adjacent Angles
Step-by-step explanation:
Let's pretend the sides of a triangle are A B and C.
The third side of a triangle is always greater tham A-B and lesser than A+B. This is called the triangle inequality theorem.
For 7 and 8, we have three lines that come together at one point (adjacent angles), and the vertical angle postulate where two mirrored angles will always have the same angle.

A pharmacist has a 12% solution and a 20% solution of boric acid. How much of each should she use to make 80 grams of a 15% solution?
Step-by-step explanation:
If x = the amount of 12% and y = the amount of 20%, then x + y = 80
Since we need 80 grams of 15%, 80(.15) = 12.
We are given that .12x + .20y = 12.
We can solve the first equation for x or y. Let's do x.
x = 80 - y
.12(80 - y) + .20y = 12
9.6 - .12y + .20y = 12
.08y = 2.4
y = 30
x = 80 - 30 = 50
Answer:
50 grams

Choose 1 answer:
А
1
B I
C
-1
D
-I
Given:
The complex number is [tex]i^{34}[/tex].
To find:
The value of given complex number.
Solution:
We have,
[tex]i^{34}[/tex]
It can be written as
[tex]i^{34}=i^{32+2}[/tex]
Using properties of exponents, we get
[tex]i^{34}=i^{32}i^{2}[/tex] [tex][\because a^{m+n}=a^ma^n][/tex]
[tex]i^{34}=i^{4\times 8}i^{2}[/tex]
[tex]i^{34}=(i^4)^8i^{2}[/tex] [tex][\because (a^{m})^n=a^{mn}][/tex]
We know that, [tex]i^4=1,i^2=-1[/tex].
[tex]i^{34}=(1)^8(-1)[/tex]
[tex]i^{34}=(1)(-1)[/tex]
[tex]i^{34}=-1[/tex]
The value of [tex]i^{34}[/tex] is -1. Therefore, the correct option is C.
Simplify. Multiply and remove all perfect squares from inside the square roots.
