Answer: 215

Step-by-step explanation:

Answer:

8p+7p+90 =180 (sum of three angles of triangles)

15p= 180-90

15p=90

p=90/15

p= 6

Step-by-step explanation:

Answer:

p=6

Step-by-step explanation:

triangles add up to 180 degrees, and a right angle =90 degrees.

from there, we can do 180-90=90 degrees then do 90/15=6. p =6

(we divide by 15 because 7+8=15)

to check, we see if all angles add up to 180.

7×6=42 8×6=48 right angle=90

42+48+90=180

Answer:

3t+4t=17.5

Step 1: Simplify both sides of the equation.

3t+4t=17.5

(3t+4t)=17.5(Combine Like Terms)

7t=17.5

7t=17.5

Step 2: Divide both sides by 7.

t=2.5

Answer:

4(4b+9)

Step-by-step explanation:

Answer:

1/18

3/2

Step-by-step explanation:

18 = 18/1 if the reciprocal means to flip the denominator and the numerator then just witched them so it would be 1/18

2/3 would be 3/2

In order to find the reciprocal of a number, we should flop it over.

In order to find the reciprocal of a fraction, then the numerator & denominator switch places.

Kindly consult the following formula for more details:-

[tex]\sf{The~reciprocal~of~a~is~\displaystyle\frac{1}{a}}[/tex]

[tex]\sf{The~reciprocal~of~\displaystyle\frac{a}{b} ~is~\frac{b}{a}}[/tex]

According to the formula, the reciprocals are;-

[tex]\sf{Reciprocal \ of \ 18:-{\boxed{\displaystyle\frac{1}{18}}}[/tex]

[tex]\sf{Reciprocal~of~\displaystyle\frac{2}{3}:- {\boxed{\frac{3}{2}}[/tex]

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

[tex]f(6) = 15[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \left \{ {{|x - 8| + 6 \ x<4} \atop {15\ x\ge 4}} \right.[/tex]

Required

Find f(6)

From the piecewise function, we have following as values of f(x):

[tex]f(x) = |x - 8| + 6[/tex]

If [tex]x < 4[/tex]

[tex]f(x) = 15[/tex]

If [tex]x \ge 4\\[/tex]

f(6) implies that x =6 and [tex]6 \ge 4[/tex]

So, we make use of the second function, which is:

[tex]f(x) = 15[/tex]

Substitute 6 for x in [tex]f(x) = 15[/tex]

[tex]f(6) = 15[/tex]

Hence, the value of f(6) is 15

Answer:

x < 25/4 or x < 6.25

Step-by-step explanation:

subtract 6 from both sides

4x < 25

divide 4 from both sides

x < 25/4 = 6.25

Answer:

x < 25/4

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Equality Properties

Step-by-step explanation:

Step 1: Define inequality

4x + 6 < 31

Step 2: Solve for x

Here we see that any number x less that 6.25 would be a solution of the inequality.

Answer:

[tex]P(X = 2) = 0.2613[/tex]

Step-by-step explanation:

Given

[tex]p = 4\%[/tex] --- proportion

[tex]x = 2[/tex] --- defective motors

[tex]n = 60[/tex] --- sample size

Required

Determine the probability that exactly 2 is defective

This follows a Poisson distribution and will be solved using:

[tex]P(X = x) = \frac{e^{-u} u^x}{x!}[/tex]

Where

u = Expected number of occurrence, and it is calculated as:

[tex]u = np[/tex]

[tex]u = 60 * 4\%[/tex]

[tex]u = 60 * 0.04[/tex]

[tex]u = 2.4[/tex]

So:

[tex]P(X = x) = \frac{e^{-u} u^x}{x!}[/tex] becomes

[tex]P(X = 2) = \frac{e^{-2.4}2.4^{2}}{2!}[/tex]

[tex]P(X = 2) = \frac{e^{-2.4}* 5.76}{2}[/tex]

[tex]P(X = 2) = e^{-2.4}* 2.88[/tex]

[tex]P(X = 2) = 0.09071795328* 2.88[/tex]

[tex]P(X = 2) = 0.26126770544[/tex]

[tex]P(X = 2) = 0.2613[/tex]

Hence, the probability that exactly 2 out of 60 will be defective is 0.2613

10-Feet My fellow friend.

Step-by-step explanation:

The foot of the ladder is

10

feet away from the base of the wall.

Explanation:

Here , the wall , top and foot of the ladder and ground makes a

right triangle of which length of ladder h=18 is regarded as

hypotenuse angle with ground is

θ=60°;cos 0= b/h or

cos 60°=b/18or b=18.cos 60=18.1/2

=9 feet

Answer:

average rate of change is 3/2

Step-by-step explanation:

Recall that the average rate of change in an interval [x1, x2], is defined as:

[f(x2)-f(x1)] / (x2 - x1)

which for the interval [0, 2] becomes:

[f(2)-f(0)] / (2 - 0)

From the graph we read that f(0)= 1 and f(2) = 4, therefore:

[f(2)-f(0)] / (2 - 0) = [4 - 1] / 2 = 3/2

Answer:

Ok when you are estimating you basically make all the numbers have no decimal or turn them all to tens. For this question you have to make 31.9 have no decimal so you turn it into 32. Then you divide 32 and 4. That equals 8. So 8 is your answer :)
