Which option is correct for finding x?

Mathematics
1 answer:
san4es73 [151]3 years ago
5 0

Answer:

35 degrees is correct(I might be wrong though.)

Step-by-step explanation:

Since this is a vertical angle question,3x° = 70 + x°

Therefore,3x - x = 2 x,making 2x=70.

so x= 70÷ 2=35. Again- I might be wrong-

Use Cramer's Rule to solve each system.<br> 5x – 3y = 8<br> -2x - y = 10
zlopas [31]

Answer:

-2, -6

Step-by-step explanation:

using cramer rule

5    -3    

-2   -1    

calculatiing the determinant = (5 x-1) - (-3x-2) = -5 -(6) = -5-6=-11

using cramer rule

to calculate x we change the coefficient of x with the answer (8,10)

8   -3

10   -1

we calculate determinant = (8x-1)-(-3x10) = -8-(-30) = -8+30 =22

to calculate x

22/-11= -2

to calculate y we change the coefficient of y with the answer (8,10)

5   8

-2   10

we calculate determinant = (5x10)-(8x-2) = 50 -(-16) = 50 +16=66

to calculate y

66/-11= -6

kicyunya [14]

Answer:

B

Step-by-step explanation:

A cylinder is like circles staked on top of each other so you want to find the are of the top circle which is 28.26 because pi r^2 (3^2)*3.14. now you found the area of the top circle. The height is 10.5 so that means there are 10.5 layers so you multiply 28.26 by 10.5 i know its confusing im new to brainly but hopefully this answer helped you  You will get 296.73 because i rounded pi to 3.14 but the answer is B

Find the balance on a deposit of $455 that earns 4% interest compounded annually for 2 years. $36.40 $491.40 $492.13 $819
STatiana [176]
A=P(1+ \frac{r}{n})^{tn}
A=future amount
P=present amount
r=rate in decimal
n=number of times per year compounded
t=time in years

given
P=455
r=4%=0.04
n=1
t=2

A=455(1+ \frac{0.04}{1})^{(2)(1)}
A=455(1+ 0.04)^{2}
A=455(1.04)^{2}
A=492.128
round
$492.13
