Calculate sin a=0.34

Answers

sina=0.34 has already been calculated for us, but to calculate the angle, which is what I'm assuming you want to know, we must take the inverse trigonometric function of sin. 

From: sina=0.34, we can derive that:

a=sin ^(-1) 0.34

Using a scientific calculator to solve this, we can see that the degrees that a is equal to (rounded to the nearest degree) is: 

a=20°

Sally buys a handbag. there was a discount of 30%. if sally paid, $20, what was the original price?

Answers

the original price is $28.57

If the discount is 30% then the amount paid is 70% of the original price. Sally paid $20, it is the discounted price, equivalent to 70%.

We need to divide $20 by 70% to get the original price or the 100%.

$20 / 70% = $28.57 original price.

Since the handbag was has discount of 30%, we multiply the original price with the 30% to get the discount value.

$28.57 * 30% = $8.57 discount

To check: deduct the discount from the original price to get the discounted price.

$28.57 - $8.57 = $20 discounted price. price paid by Sally

Find the sum of 13/20 and 0.72
Give your answer as a decimal.

Answers

The sum of 13/20 and 0.72 when expressed in decimal form gives us the answer as; 1.37.

How to convert fraction to decimal?

We want to find the sum of ¹³/₂₀ and 0.72

This is expressed as;

¹³/₂₀ + 0.72

Now, we want to express the fraction as a decimal. Thus, let us convert to decimal as; ¹³/₂₀ = 0.65

Thus, we now have the decimal expression;

0.65 + 0.72 = 1.37

Thus, we can conclude that the sum of 13/20 and 0.72 when expressed in decimal form gives us 1.37.

A fraction reduces to 36. If its denominator is 6x5, what is its numerator?

Answers

If you would like to find the numerator of a fraction, you can do this using the following steps:

denominator ... 6 * 5 = 30
numerator ... x = ?

36 = numerator / denominator
36 = x / 30
x = 36 * 30
x = 1080

The correct result would be 1080.

Match the formula to the correct figure.

What goes where? :D


Will give out Brainliest Answer!!!

Answers

It is asking you to move the right formula with its match.

Formula for a cylinder: π*R^2*H
So the first option goes to the first shape.

Example: 
Radius=5
Length=10
π≈3.14
3.14*5²*10
=725 cm³ for the answer. 

Formula for a square: l*w*h

So the 4th option goes with the 2nd shape. 

Example: l=5 w=5 h=5
(Length * Width * Hieght) 

5*5*5=125 for the answer.

Formula for a cone is: 1/3π*r^2*h
So the second option goes to the 3rd shape. 

Example: r=3 h=11 
π≈3.14
(1)/(3) *3 ^(2) *11=33
33 is your answer. 

Formula for the pyramid would be: 1/3*b*h
So the 3rd option would go to the 4th shape.

Example: 
b=2 h=10
(1)/(3) *2*10=6.666667
Rounded: 6.6

Hope this helps!~

(Look at the attachment)

These are the formula's for each of the 3 dimensional shapes. They're asking you to match the formula to the correct shape. 

Here, you'll need just a bit of memorizing. 

Orange figure : Cylinder
V=πr²h

Yellow figure: Square
length * width * height
V = l
×w×h

Blue figure: Cone
V = 1/3
πr²h

Red figure: Pyramid
 V = 1/3 b * h

Pi = 3.14
h = height
b = base
r = radius (half of diameter)
v = volume
