10(x+3)=9
mmmmmmmmmmmmmmmmm

Answers

Answer 1
Answer: divide both sides by 10
x+3=0.9
minus 3
x=2.1
Answer 2
Answer: Solutions 

Divide both sides by 10

x+3=9 / 10

Subtract 3 from both sides

x=9 / 10 −3

 Simplify 9 / 10 −3 to −21 / 10

x=−21 / 10


Decimal = -2.1

A surveyor has poles A, B, and C set to form a right triangle with the right angle at B. If the distance from A to B is 35 meters and the distance from B to C is 25 meters, what is the distance from A to C? He can t measure it because there is a deep pond between points A and C.

Answers

It's about Pythagorean theorem.

AB*AB + BC*BC = AC*AC, so:

35*35 + 25*25 = AC*AC
1225 + 625 = AC*AC
1850 = AC*AC

So AC is a root of 1850, which is ~43 (exactly: 43,01162633521313)

It means that distance between A and C is 43 meters and some milimeters.

If f(x+5)=x^2+kx+30 what is K equalled to?

Answers

f(x+5) means for every x, it is x+5

ok so since it is 2nd degree, we do exponent
f(x)=x^2
f(x+5)=(x+5)^2=x^2+10x+25
we need 5 more
f(x)=x^2+5
f(x+5)=x^2+10x+25+5=x^2+10x+30

Step-by-step explanation:

Last year at a certain high school, there were 132 boys on the honor roll and 90 girls on the honor roll. This year, the number of boys on the honor roll increased by 25% and the number of girls on the honor roll increased by 20%. By what percentage did the total number of students on the honor roll increase? Round your answer to the nearest tenth (if necessary).

Answers

The percentage of increase of total number of students on the honor roll is obtained as 22.97%.

What is percentage?

A percentage is a value that indicates 100th part of any quantity.

A percentage can be converted into a fraction or a decimal by dividing it by 100.

And to convert a fraction or a decimal into percentage, they are multiplied by 100.

The number of boys and girls on the honor code last year is given as 132 and 90.

Then, the total number is 132 + 90 = 222.

When, the number of boys increased by 25%, it can be obtained as,

⇒ 132 + 25% × 132 = 165

And, the number of girls increased by 20% can be obtained as,

⇒ 90 + 20% × 90 = 108

Now, the total number of students is 165 + 108 = 273.

The percent increase can be obtained as follows,

Change in the total number ÷ Initial number × 100

⇒ (273 - 222) ÷ 222 × 100 = 22.97%

Hence, the percent value of the increase in the number is 22.97%.
