Step-by-step explanation:

Answer:

No because one side is 8 and the other is 18

Step-by-step explanation:

Answer:

a, t = (p - 4)/5

b. t =√(a + 4)

c. t = d/(5-f)

Step-by-step explanation:

a. p = 5t + 4

To make t the subject of the equation, subtract 4 from both sides

p - 4 = 5t + 4 - 4

p - 4 = 5t

Divide both sides by 5

(p - 4)/5 = t

t = (p - 4)/5

b. a = t2 - 4

to make t the subject, add 4 to both sides

a + 4 = t2 - 4 + 4

a + 4 = t2

find the root of both sides

t =√(a + 4)

c. d = t(5 – f)

to make t the subject, divide both sides by 5 - f

d/(5-f) = t(5 – f)/(5 – f)

t = d/(5-f)

Answer:

70.028175

Step-by-step explanation:

To convert a radian measurement to a degree measurement, multiply the angle by the conversion ratio.

degrees = radians ×  (57.29578 or 180/pi)

11/9 rad = 70.028175°

Answer:

5. 60%

6. $12,331

Step-by-step explanation:

Cross multiply:

5.

[tex]\frac{137.94}{229.90}=\frac{x}{100}[/tex]

100(137.94)= 13,794

13,794/229.9= 60, 60%

6.

[tex]\frac{616.55}{x}=\frac{5}{100}[/tex]

Step-by-step explanation:

Answer:

0.6568 = 65.68% probability that she would be correct.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so.

This means that:

[tex]\mu = \frac{45000 + 45500 + 44500 + 46000 + 44000}{5} = 45000[/tex]

Standard deviation of 1500 units.

This means that [tex]\sigma = 1500[/tex]

What is the likelihood that she would be correct if she predicts sales between 43000 and 46000?

This is the pvalue of Z when X = 46000 subtracted by the pvalue of Z when X = 43000. So

X = 46000

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{46000 - 45000}{1500}[/tex]

[tex]Z = 0.67[/tex]

[tex]Z = 0.67[/tex] has a pvalue of 0.7486

X = 43000

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{43000 - 45000}{1500}[/tex]

[tex]Z = -1.33[/tex]

[tex]Z = -1.33[/tex] has a pvalue of 0.0918

0.7486 - 0.0918 = 0.6568

0.6568 = 65.68% probability that she would be correct.

Answer:

if you're trying to find z it equals 6

Step-by-step explanation:

because 60 ÷ 10 = 6

Answer:

divide 10 from z

z is alone

now divide 10 from 60

you get 6

z=6

Given:

a¹²b⁴, a⁴b⁸, a²⁴b¹⁶ and a¹²b²⁰.

To find:

The GCF of given terms.

Solution:

Greatest common factor (GCF): To find the GCF of two or more numbers, we need to find the product of their prime factor with their maximum powers.

The given terms are

[tex]a^{12}b^{4},a^{4}b^8, a^{24}b^{16}, a^{12}b^{20}[/tex]

Here, each term has two prime factors a and b. The highest power of a is 24 and the highest power of b is 20. So, the GCF of given terms is

[tex]GCF=a^{24}\times b^{20}[/tex]

[tex]GCF=a^{24}b^{20}[/tex]

Therefore, the GCF of a¹²b⁴, a⁴b⁸, a²⁴b¹⁶ and a¹²b²⁰ is a²⁴b²⁰.

Answer:

The equation of the plane is represented by [tex]\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1[/tex].

Step-by-step explanation:

Algebraically speaking, a plane can be represented by following vectorial product:

[tex](a,b, c)\,\bullet\,(x,y,z) = 1[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex], [tex]c[/tex] - Plane coeffcients.

[tex]x[/tex], [tex]y[/tex], [tex]z[/tex] - Coordinates.

We need three distinct points to determine all coefficients. If we know that [tex](x_{1},y_{1},z_{1}) = (0,9,9)[/tex], [tex](x_{2},y_{2}, z_{2}) = (9,0,9)[/tex] and [tex](x_{3},y_{3},z_{3}) = (9,9,0)[/tex], the system of equations to be solved is:

[tex]9\cdot b + 9\cdot c = 1[/tex] (1)

[tex]9\cdot a + 9\cdot c = 1[/tex] (2)

[tex]9\cdot a + 9\cdot b = 1[/tex] (3)

The solution of this system is [tex]a = \frac{1}{18}[/tex], [tex]b = \frac{1}{18}[/tex], [tex]c = \frac{1}{18}[/tex].

Hence, the equation of the plane is represented by [tex]\frac{1}{18}\cdot x + \frac{1}{18}\cdot y + \frac{1}{18}\cdot z = 1[/tex].

Answer:

Step-by-step explanation:

PQ=RS

x-1=3x-7

-2x=-6

x=3

So the length of PS is

x-1+x+3x-7

5x-8, since x=3

5(3)-8

15-8

PS=7

y=5

x=30

Explanation: since all 3 angles of triangles are marked equal we can see that it is equilateral which means 8y=40 so y=5. Then we can find that the other triangle is an 120 30 30 triangle thus x is 30. You can also do this if you can see straight away that the big triangle is a 30-60-90 triangle and just use 90-60.

Answer:

[tex]7x+2y = -17[/tex]

Step-by-step explanation:

We have the following equations:

[tex]2x+3y = -5[/tex]

[tex]5x-y = -12[/tex]

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

[tex](2x+5x)+(3y-y) = -5-12[/tex]

[tex]7x+2y = -17[/tex]

Answer: It really dosen't matter if its repeating. If it's repeating just put a line ABOVE THE REPEATING PART. I will explain a little bit so you know what I mean.

Step-by-step explanation: So say you divide 2 by 3 your going to get 0.66666666666. You don't have to put all those 6's. All you have to do is put 0.66 with a line above the two sixes. This will indicate you have a repeating decimal. And this works with any repeating number!

Answer:

C. 15

Step-by-step explanation:

The following proportional can be set-up for the figure given:

[tex] \frac{x + 3}{x} = \frac{10 + 2}{10} [/tex]

Solve for x

[tex] \frac{x + 3}{x} = \frac{12}{10} [/tex]

[tex] \frac{x + 3}{x} = \frac{6}{5} [/tex]

Cross multiply

[tex] 5(x + 3) = x(6) [/tex]

[tex] 5x + 15 = 6x [/tex]

15 = 6x - 5x

15 = x

x = 15
