Correct choice is D

Answer:

110

Explanation:

First move the decimal point over to the left twice.

.375

Then multiply 80 by .375 like this :

.375 x 80 = 30

Lastly, add 30 to 80 and put the dollar sign.

Answer:

6 complete costumes

Step-by-step explanation:

he has 27/2 total fabric

1 costume requires 1 2/4 + 3/4 of fabric, which is 2 1/4

we divide 27/2 by 9/4

27/2 x 4/9 = 6

Answer:

3: D) 11

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.

Answer:

Step-by-step explanation:

m=72° (corresponding angles)

n=m=72° (corresponding angles)

p=180-(80+72)=180-(152°)=28°

x=np=5

y=nm=8

z=pm=12

Answer:

P: the principal, the amount invested

A: the new balance

t: the time

r: the rate, (in decimal form)

Step-by-step explanation:

Ex1: If $1000 is invested now with simple interest of 8% per year. Find the new amount after two years.

P = $1000, t = 2 years, r = 0.08.

A = 1000(1+0.08(2)) = 1000(1.16) = 1160

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.

Step-by-step explanation:

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

Answer:

B. Not enough information.

Step-by-step explanation:

We are given that all three angles of ∆DEF is congruent to all the three corresponding angles of ∆XYZ. However, this is is not enough to prove that they are both congruent to each other. There's no information about any of tge side length.

AAA is not a criterion that proves two triangles are congruent.

Therefore, we will conclude that there is not enough information.

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.

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.
