Answer:

p = 4

Step-by-step explanation:

3p + 8 = 20

3p = 20 - 8

3p = 12

p = 12/3

p = 4

Answer:

see below

Step-by-step explanation:

2p + 8 = 20 - p

add p to both sides

2p + p + 8 = 20 - p + p

combine like terms

3p + 8 = 20

subtract 8 from both sides

3p + 8 - 8 = 20 - 8

combine like terms

3p = 12

divide both sides by 3

3p / 3 = p

12/3 = 4

we're left with p = 4

Answer:

total number of marbles = 10

number of red marbles = 4

p(blue) = 3/10

Answer: 12 yearly admissions and 38 single admissions

Step-by-step explanation:

Let x be yearly membership

Let y be single admission

x+y=50 --> # of tickets sold

35.25x+6.25y=660.50 --> $ of tickets

Use elimination method to solve (multiply equation 1 by -3525 and equation 2 by 100)

-3525x-3525y=-176250

+  3525+625y=66050

-----------------------------------

-2900y=-110200

y=38

Substitute y=38 into equation 1

x+38=50

x=12

Therefore, 12 yearly admissions and 38 single admissions were sold

Answer:

17 1/4mph

Step-by-step explanation:

As you can see, Sarah rides her bike 5 3/4 in 1/3 hours. All you need to do is multiply 5 and 3/4 by 3 since it's thirds. 5x3=15. 3/4x3=9/4. 9/4= 2 1/4. 15+2 1/4= 17 1/4mph.

Answer:

[C] 29 Miles

Step-by-step explanation:

Given that the vessel sails 41 miles S 45° E.

We need to determine the how far south the vessel has sailed.

Let us use the Pythagorean theorem to find the distance of the vessel has sailed.

Thus, we have,

[tex]Cos 0= \frac{adj}{hyp}[/tex]

Substituting [tex]0 = 45[/tex]° , [tex]adj = x[/tex], and [tex]hyp = 41[/tex]

Hence, we get,

[tex]cos[/tex] [tex]45 = \frac{x}{41}[/tex]

Simplifying, we have,

[tex]0.71 = \frac{x}{41}[/tex]

Multiplying both sides by 41, we have,

[tex]29.11 = x[/tex]

Rounding off to the nearest integer, we have,

[tex]29 = x[/tex]

Thus, the vessel has sailed 29 miles South.

Therefore, Option C is the correct answer.

Answer:

45%

Step-by-step explanation:

First, let's set up a fraction of how much money she spent for fruit out of the total amount of money she spent.

[tex]\frac{9}{20}[/tex]

For a percentage, we need a fraction out of 100. To do this, we can multiply  the fraction by 5/5 (5*20=100). Notice we can only do this since 5/5 is equivalent to 1, so you are technically multiplying the fraction by 1.

[tex]\frac{9}{20}*\frac{5}{5}=\frac{45}{100}[/tex]

A percentage is just the numerator of a number over 100 therefore it is equal to...

The solution of the logarithmic equation provided using the log rule is,

[tex]x=-3[/tex]

When the base of the logarithm in an equality expression is same, then the number are directly compared to each other.

The given logarithmic equation in the problem is,

[tex]\log_7(x -4) = \log_7(4x +5)\\[/tex]

Compare the number for the same base as,

[tex](x-4)=(4x+5)[/tex]

Solve the equation further as,

[tex]4x-x=-4-5\\3x=-9\\x=\dfrac{-9}{3}\\x=-3[/tex]

Thus, the solution of the logarithmic equation provided using the log rule is,

Answer:

CDA≈27,6°

Step-by-step explanation:

First we solve the x using pythagorean theorem

a^2+b^2=c^2

x^2+6^2=6.5^2

x^2+36=42.25      ||-36

x^2=42.25-36

x^2=6.25               ||√

√x^2=√6.25

x=2.5cm

now we can solve y

y = 23cm-9cm-2.5cm

y=11.5cm

now we can solve CDA angle with tanα

tanα=[tex]\frac{a}{b} \\[/tex]

tanα=6cm/11.5cm
