Answer:

x = 4

Step-by-step explanation:

the given figure is of an isoceles triangle.

The two angles opposite are congruent(i.e78 degrees) .

That is the sides opposite to them are also congruent.

I. e 4x + 23 = 10x - 1

I. e 4x - 10x = -1 -23

I. e -6x = -24

I. e -x. = -24/6

Dividing by 6 to 24 we get,

-x = -4

therefore by removing the minus sign from both the sides,

the answer comes x = 4

A peeting zoo has 5 lambs 11 rabbits 4 goat and 4 piglets find the ratio of goat to the total number of animals.then explain its

Otrada [13]

Ratio is the number of something beside another number of something i.e. ( There are 2 boys and three girls so the Ratio would be 2:3) Therefore the answer would be 5:11:4:4. Yiou want the goats ratio of the total number of animals so we will add all animals EXcEPT the goat. 5+11+4 = 20 so the ratio would be 4:20

The power increases by 21% per hour. 21% written as a decimal is 0.21.

Because it increases you would multiply the starting value by 1.21 times the number of hours (t).

That needs to be less than or equal to 100,00

The equation would be:

C: 15,040(1.21)t ≤ 100,000

Answer:

30500 = 3.05·10^4

Step-by-step explanation:

Your calculator can do this for you. You may need to set the display to scientific notation, if that's the form of the answer you want.

This can be computed by converting both numbers to standard form:

(5·10^2) +(3·10^4)

= 500 +30000 = 30500 = 3.05·10^4

Addition of numbers in scientific notation in general requires that they have the same power of 10. It may be convenient to convert both numbers to the highest power of 10.

5·10^2 + 3·10^4

= 0.05·10^4 +3·10^4 . . . . now both have multipliers of 10^4

= (0.05 +3)·10^4

= 3.05·10^4

Let f(x)=3x and g(x)=x^2+5. Perform function operation g(x)/f(x). State the domain.

tangare [24]

We have that

f(x)=3x
g(x)=x²+5
g(x)/f(x)=[x²+5]/[3x]

that new function will exist for all real numbers except the value of zero, value for which it becomes indefinite

the domain is the interval (-∞,0) U (0,∞)
