After taking typing lessons for three months, Johanna can type 285 words in five minutes. How many words can she type in 13 minutes?

Answer:

1. Y = 2, 1, 4, 7, 10

2. Y = -12, -8, -4, 0, 4

3. Y = -7, -5, -3, -1, 1

Step-by-step explanation:

all of the numbers in the x value you just substitute in the x place in problem

1. Y = 3x + 4

x: -2, -1, 0, 1, 2

Y = 3(-2) + 4

Y = -6 + 4

Y = -2

You then have:

x: -2, -1, 0, 1, 2

y: -2,

Y = 3(-1) + 4

Y = -3 + 4

Y = 1

You then have:

x: -2, -1, 0, 1, 2

y: -2, 1

just continue substituting each x variable into the x place to get your y variable.

I know you asked for the first 6 but I feel like if I just give you the answers to all of them you will not learn it, so I only gave the first 3, and I recommend trying to do the last 3 yourself. I'm sure you'll do well. <3

Answer:

x = 30°

Step-by-step explanation:

Since m and n are perpendicular, then

y + 70° = 90° ( subtract 70° from both sides )

y = 20°

thus 40 + y = 40° + 20° = 60°

Then

x + 60° = 90° ( subtract 60° from both sides )

x = 30°

Answer:

Solving the given formula for v2 gives us:

[tex]a(t_2-t_1)+v_1 = v_2[/tex]

Step-by-step explanation:

Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.

Given equation is:

[tex]a = \frac{v_2-v_1}{t_2-t_1}[/tex]

Multiplying both sides by t2-t1

[tex](t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1[/tex]

Adding v1 to both sides of the equation

[tex]a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2[/tex]

Hence,

Solving the given formula for v2 gives us:

[tex]a(t_2-t_1)+v_1 = v_2[/tex]

Answer:

x=-10

Step-by-step explanation:

Move like terms to the same side

2x+6-x=-4

x=-4-6

x=-10

2x+6=x-4

subtract x from both sides

x+6=4

subtract 6 from both sides

x=-10

because you have a quotient when you divide and has the same rules as multiplication

Answer:

5(3x+4)=23

5*3=15 5*4=20

15x+20=23

      -20=-20

15x=3

divide by 15 from both sides

x=0.2

Step-by-step explanation:

Answer:

5(3x+4)=23

5*3=15 5*4=20

15x+20=23

     -20=-20

15x=3

divide by 15 from both sides

x=0.2

Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5

amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.

Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".

Answer:

y=35 x=145

Step-by-step explanation:

y is equivalent to 35

180-35=145

Answer:

x = 145

y = 35

Step-by-step explanation:

x and the 35 degree angle are supplementary angles, so x + 35 = 180.

solve for x, x = 145. the 35-degree angle and angle Y are corresponding angles, so the value of y will be 35.

We have to find the pairs of numbers which are relatively prime.

Relatively prime number: The numbers in which gcd 1 are called relative prime numbers.

a.9 and 15

GCD(9,15)=3

9 and 15 are not relatively prime.

b.9 and 40

GCD(9,40)=1

Hence, 9 and 40 are relatively prime.

c.9 and 21

GCD(9,21)=3

9 and 21 are not relatively prime.

d.15 and 21

GCD(15,21)=3

15 and 21  are not relatively prime.

e.21 and 40

GCD(21,40)=1

21 and 40 are relatively prime.

Answer:

33.34%.

Step-by-step explanation:

Given that,

The actual price of the shirt = $36

Price on sale = $24

We need to find the percent of the decrease. The formula for the percentage is given by :

[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]

Putting all the values,

[tex]\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%[/tex]

So, the percentage decrease in the price of the shirt is 33.34%.

Answer:

59049 digits

Step-by-step explanation:

Given

Digits = 0 to 9

Required

Determine number of 5 digit pins that must not contain 0

There are 10 digits.

Since the pin must not contain 0, there are 9 digits left to select from.

The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.

The 1st digit of the 5 could be any of the 9 digits

The 2nd could be any of the 9 digits

The 3rd could be any of the 9 digits

The 4th could be any of the 9 digits

The 5th could be any of the 9 digits

Hence, number of selection is calculated as this:

Selection = 9 * 9 * 9 * 9 * 9

Selection = 59049
