11 more than four times a number is 39

Mathematics
1 answer:
Aliun [14]3 years ago
4 0

Hello!

Your answer is: 7

(X = "<em>A number</em>")

<em>"11 more than four times a number is 39"</em> in equation form is: 4X + 11 = 39

to solve, first subtract 11 from both sides:

4X = 28

then divide both sides by 4 to get:

X = 7

I hope this helps, and have a nice day!

Find the measure of the side of the right triangle whose length is designated by a lowercase letter. (see attachment)
PilotLPTM [1.2K]

Answer:

a≈18 cm

Step-by-step explanation:

     we have given:

an angle,

the adjacent side and

     we need to find:

the opposite side

     

we know that the definition of

tan of an angle = opp. side/ adj. side

              tan 61° = a/ 10

multiply both sides by 10

        10 * tan61° = a

   18.04047755 = a

                      18 ≈ a

A door to a playhouse is 50 inches tall. Which of the following is another measure equal to the height?
Effectus [21]

Answer:

4 ft 2 in.

Step-by-step explanation:

A door to a playhouse is 50 inches tall

we know that

1 in---------------> is 0.0833333 ft

so

50 in-------------> 50*0.0833333---------> 4.167 ft

4.167 ft----------> [4 ft+0.167 ft]

remember that

1 in---------------> is 0.0833333 ft

X in----------------> 0.167 ft

X=0.167/0.0833333----------> X=2 in

4.167 ft----------> [4 ft+0.167 ft]--------> [4 ft+2 in]

alisha [4.7K]

Answer:

b = \frac{1}{5}

Step-by-step explanation:

35b = 7

Divide both sides by 35.

b = \frac{7}{35}

Reduce the fraction \frac{7}{35} to the lowest terms by extracting and canceling out 7.

b = \frac{1}{5}

Hope it helps and have a great day! =D

How does changing the number outside the parentheses of an exponential function change your graph? y = a(b)^x
Zarrin [17]

Answer:

See Below.

Step-by-step explanation:

We have the function:

y=a(b)^x

Depending on the behavior of the coefficient, many things can happen. The parent exponential function has a=1. If a is something other than 1, however, there are three main changes.

Let’s use b=2 to illustrated the examples.

(In the graphed examples, below, the parent function (with b=2) is the red curve.)

  • If <em>a</em> is a positive, rational number greater than 1.

If a is a positive number other than 1, say 2, then this represents a vertical stretch.

In other words, our function is stretched closer to the y-axis.

(This is the blue curve. It is closer to the y-axis than the parent function (red curve).)

  • If <em>a</em> is a positive, rational number greater than 0 but less than 1.

If a is a number between 0 and 1 (so a fraction), say, 1/2, then this represents vertical compression.

In other words, our function gets farther away from the y-axis.

(This is the black curve.)

  • If <em>a </em>is a negative.

If a is <em>negative</em>, then this means that the graph was flipped over the x-axis.

(This is the green curve.)

Note that if we have something such as a=-2 or a=-1/2, this means that the function we flipped over the x-axis first and <em>then</em> vertically stretched or compressed.

(And example of this is illustrated with the orange curve).
