Answer: 5X +40 = 100

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\frac{a^{m}}{a^{n}}=a^{m-n}\\\\a^{m}*a^{n}=a^{m+n}\\\\\frac{125t^{-4}}{5^{-3}}*625*t^{-8}\\\\=\frac{5^{3}t^{-4}}{5^{-3}}*5^{4}*t^{-8}\\\\=5^{3-[-3]+4}*t^{-4-8}\\\\=5^{3+3+4}t^{-12}\\\\=5^{10}t^{-12}\\\\=\frac{5^{10}}{t^{12}}[/tex]

Answer:

x=-10

Step-by-step explanation:

[tex]2(x+3)=x-4[/tex]

distributive property on left side:

[tex]2x+6=x-4[/tex]

subtract x from both sides

[tex]x+6=-4[/tex]

subtract 6 from both sides

[tex]x=-10[/tex]

Answer:

-10

Step-by-step explanation:

2(x+3)=x-4

Distribute (multiply everything in parenthesis):

2x+6=x-4

Subtract -x from both sides

X+6=-4

Subtract 6 from from both sides:

X=-10

Answer:

1200 feet

Step-by-step explanation:

A scale is a representative faction which can be used to either increase or decrease the size or dimensions of an object.

scale = [tex]\frac{model height}{actual height}[/tex]

[tex]\frac{2inches}{160 feet}[/tex] = [tex]\frac{15 inches}{actual height}[/tex]

actual height = [tex]\frac{15 *160}{2}[/tex]

                      = [tex]\frac{2400feet}{2}[/tex]

                      = 1200

actual height = 1200 feet

The actual height of the skyscraper is 1200 feet.

Complete Question:

Corinne is taking a train into the city. The train travels at a rate of 45 miles per hour. Which quantity depends on the other?

A. The distance traveled depends on the number of hours traveled.

B. The number of hours traveled depends on the speed of the train.

C. The speed of the train depends on the distance traveled.

D. The speed of the train depends on the number of hours traveled.

Answer:

A. The distance traveled depends on the number of hours traveled.

Step-by-step explanation:

Recall:

Distance traveled = speed * time

The distance between or route taken from one point to the other is usually fixed

Here, the speed of the train , rate is constant, hence for the journey, speed is constant ;

Speed = K

Distance = K * time

Hence, the distance traveled in this scenario depends on the time of travel.

Step-by-step explanation:

Answer:

V=25

Step-by-step explanation:

Solve for

v

v

by simplifying both sides of the equation, then isolating the variable.

v

=

25

Answer: V =  25

Step-by-step explanation:

5^ 7v / 5 = 5^35

7v=175

(7v/7)=(175 /7 )

v=25

Answer:

9 percent

Step-by-step explanation:

Answer:

3%

Step-by-step explanation:

1st Method: Increase Formula = (Last value-first value)/(first value)

Increase = (309-300)/300 = 9/300 = 3/100

= 0.03 or 3%

2nd Method: 309/300 = 103/100 = 1.03 (increase over 1 is 0.03 = 3%

Answer:

m∠B = 63°

AB = 26.4

AC = 23.6

Step-by-step explanation:

m∠B = 90 - 27 = 63°

Sin 27 = 12/AB

AB (sin 27) = 12

AB = 12/sin 27 = 26.4

Tan 27 = 12/AC

AC (tan 27) = 12

AC = 12/tan 27 = 23.6

Answer:

13(2b-1)

Step-by-step explanation:

Both have the factor 13.

Answer:

-10

Step-by-step explanation:

Note that the points plotted on the line is by 2 (essentially, each line signifies 2).

The blue point is on the 5th line from the 0. 5 x -2 = -10

-10 is your answer.

$0.50

Answer:

Initial value is (0 , 24) or just y = 24

Step-by-step explanation:

Initial value of a linear function is the y intercept

y = -3x + 24

x = 0, y = 24

Answer:

-56

Step-by-step explanation:

That is because the 56 is below sea level, not above it, so it would be negative 56

Hope that helps!

-56ft

Since it is BELOW sea level it would be considered a negative number. If it were ABOVE sea level then it would be a positive number. Another way to think about this:

Above Sea Level = +

Below Sea Level = -

Hope this helps and have a nice day.

Step-by-step explanation:

Answer:

x=2.142137

Step-by-step explanation:

Solve Exponent.

12x=205

log(12x)=log(205)(Take log of both sides)

x*(log(12))=log(205)

x=

log(205)

log(12)

x=2.142137

Answer:

-10%

Step-by-step explanation:

precent change = 135 - 150

(divide both sides by 150)

precent change = -0.1

(multiply both sides by 100 so change to precent)

precent change = -10%

Answer:

10%

Answer:

y = 2x + 11

Step-by-step explanation:

y = mx + b, m is the slope which we already, it is 2. B is the y-intercept, which we don't know. To find the y-intercept, you plug in the coordinates into the equation so far, which is y = 2x + b.

y = 2x + b

5 = 2(-3) + b

5 = -6 + b

11 = b

So our equation is y = 2x + 11

Answer:

i believe it would be 16.

Step-by-step explanation:

Answer:

Answer is x = 14.665 which rounded off is 14.67

All I did was Cos 39 = x / 55

0.26664293236 = x / 55

0.26664293236 × 55 = x

x = 14.665

x = 14.67
