Mathematics
1 answer:
Hatshy [7]4 years ago
6 0

Answer:

The answer is 53

Step-by-step explanation:

We know that all the angles in a triangle add up to 180. So we do 37+90= 127

180-127= 53

Hope I helped!

405 degrees to radians in terms of pi
Katena32 [7]
Convert degrees to radians, multiply by π/180° , since a full circle is 360 ° 360 or 2π radians.
− 405°⋅ π /180° radians

Cancel the common factor of 45 .
-9 ⋅ π/4 radians

Combine −9 and π/4
-9π/4

Move the negative in front of the fraction.
-9π/4 radians

X^2/9+2y/7 help me solve
vfiekz [6]

So firstly, we have to find the LCD, or lowest common denominator, of 9 and 7. To do this, list the multiples of 9 and 7 and the lowest multiple they share is going to be your LCD. In this case, the LCD of 9 and 7 is 63. Multiply x^2/9 by 7/7 and 2y/7 by 9/9:

\frac{x^2}{9}\times \frac{7}{7}=\frac{7x^2}{63}\\\\\frac{2y}{7}\times \frac{9}{9}=\frac{18y}{63}\\\\\frac{7x^2}{63}+\frac{18y}{63}

Next, add the numerators together, and your answer will be: \frac{7x^2}{63}+\frac{18y}{63}=\frac{7x^2+18y}{63}

Hey there!

In this problem, we'll just be finding the surface area of a rectangular prism. In this example, a surface area is a sum of all the areas of each individual face. On this rectangular prism, we have 6 faces, and two of each kind. Our formula is:

SA = 2(lw + wh + lh)

Notice how it has a 2. That two is because those two variables just applies for one side, and there's two for each type of side. On this diagram, the rightmost side's area would be the width (32) times the height (49) and the product would be the area. Let's plug in our numbers:

SA = 2(41 * 32 + 32*49 + 41*49)

Multiply:

SA = 2( 1312 + 1568 + 2009) =

Add:

SA = 2(2880 + 2009)

SA = 2(4889)

SA = 9778 ft squared, or C.

Hope this helps!

The price of a toy usually costs £50 is increased to £65 work out the percentage increase
I am Lyosha [343]

Answer:

Step-by-step explanation:

10% of 50 = 5

5% of 50 = 2.5

to get to 65 u do 5+5 = 10 so so far that is 20% but 20% only gets u to 60 so u add another 10% to reach 65

u have used 30% so the answer to yr question is 30%
