Unit conversion is a way of converting some common units into another without changing their real value. Ms. Aluma is using the correct option.

Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm, though the real measurement is still the same the units and numerical values have been changed.

Given that Ms Aluma is 165 cm tall and She wants to find her height in meters. Therefore, if we divide her height in centimeters by 100 to find her height in meters.

Since 1 meter is equal to 100 cm, therefore, the method used by Ms. Aluma is correct. Therefore, the height of Unit conversion is,

Height of Ms. Aluma = 165 cm

                                  = 165/100 meters

                                  = 1.65 meters

Hence, Ms. Aluma is using the correct option.

Answer:

B

Step-by-step explanation:

First, a proportional ratio needs to have same equivalent fraction when simplified. So, for the option B, 5/10 can reduce to 1/2 whereas 6/11 and 7/12  do not reduce to 1/2. Therefore, the option B doesn't have a proportional relationship.

90° + 2x-2 + x+5 = 180° [Angle sum property of triangle]

=> 90 + 2x + x - 2 + 5 = 180°

34 yards of carpet weighs 51 pounds.

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given that, 20 yards of carpet weighs 30 pounds.

Here, 1 yard of carpet weighs = 30/20

= 1.5 pounds

34 yards of carpet weighs

= 34×1.5

= 51 pounds

Therefore, 34 yards of carpet weighs 51 pounds.

Answer:

yes u are right on the answer

Answer:

yes

Step-by-step explanation:

corresponding angles have the same measurement

Answer: I still don’t see it :/

Step-by-step explanation:

Answer:

(4x + 1) + (5x + 4) + E = 180.

Simplify: Combine the x values

4x + 5x = 9x.

Now add 4 + 1 = 5.

So far we have; 9x + 5 + E = 180.

180 - 5 = 175.

9x = 175

175/9 = 19.4 repeated. X = 19.4 repeated.

Substitute in the value we have so far.

(4 x 19.4 repeated + 1) + (5 X 19.4 repeated + 4) = 180

So, E must be 0 for this equation to work.

Answer: 7693cm

Step-by-step explanation:

The volume of a cone is given as:

= 1/3πr²h

where π = 3.14

radius = 3.5cm

height = 12

Volume = 1/3πr²h

= 1/3 × 3.14 × 3.5² × 12

= 153.86cm³

Therefore, the amount of water that is needed to fill 50 cups will be:

= 153.86 × 50

= 7693cm

Vertical angles are a pair of non-adjacent angles formed when two lines intersect. you only told me to name a pair but i dont  know what u mean you didn't give a diagram.

Since the triangle is a right angled, to find one side we should use the pythagoras theorem.

The longed side of the triangle is called the hypotenuse.

In equation form:  x² + y² = z²

Therefore: 12² + x² = 13²

114+x²= 169

x²= 169-114

x²= 55

x = 7.41

Therefore the length of AC = 7.41

Answer:

d = 6.1m

n = 7km

Step-by-step explanation:

To find the variables, use tan

⇒ tan = [tex]\frac{opposite}{adjacent}[/tex]

finding d:

⇒tan 63 = [tex]\frac{d}{3.1}[/tex]

tan of 63 is 1.963

⇒ 1.963 = [tex]\frac{d}{3.1}[/tex]

multiply 3.1 on both sides

⇒ 1.963 x 3.1 = [tex]\frac{d}{3.1}[/tex] x 3.1

⇒ 6.0853 = d

round to the nearest tenth:

⇒ 6.0853 = 6.1

finding n:

⇒ tan 45 = [tex]\frac{7}{n}[/tex]

tan of 45 is 1

⇒ 1 = [tex]\frac{7}{n}[/tex]

multiply 7 on both sides:

⇒ 1 x 7 = [tex]\frac{7}{n}[/tex] x 7

7 = n

Answer:

D = 1.4, N =

Step-by-step explanation:

To get D you need to find the cosine of 63 degrees

Cosine(63) = D / 3.1

Multiply by 3.1 to isolate D :

3.1Cosine(63) = D

Put it into a calculator and you'll get 1.4.

Also, it's a 45-45-90 triangle so the 2 legs will be equal to each other.

Proof: To get N put you have to do the tangent of 45 degrees

Tan(45) = 7 / N

Now you can't to do this you have to multiply the both sides by N

N(tan(45)) = 7

Then divide both sides by (tan(45))

N = 7 / (tan(45)

Put it into the calculator and you'll get

Step-by-step explanation:

principle (p) = $4700

rate (r) = 1.65%

time (t) = 4.5 years

interest = (p × r × t)÷100

= ($4700 × 1.65 × 4.5)÷100

= $348.975

The balance in his account at the end of 4.5 years is $5048.975.

Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.

Simple Interest = (Principal × Rate × Time) / 100

Given;

Enrique deposited $4,700 into an account.

Enrique earned 1.65% annual simple interest on the money in the account.

Time= 4.5

Now,

SI= 4700*1.65*4.5/100

SI=348.975

Total= 4700+348.875

=5048.975

Therefore, the amount after simple interest of 1.65% will be $5048.975.
