The fraction 24/35 is  equal to 68.57% when converted to a percentage.

To convert a fraction to a percentage, you can follow these steps:

Divide the numerator of the fraction by the denominator.

In this case, divide 24 by 35: 24 ÷ 35

= 0.6857142857142857

Multiply the result from 0.6857142857142857 by 100 to get the percentage.

Multiply 0.6857142857142857 by 100

0.6857142857142857 × 100 = 68.5714285714

4/10 of his cards are baseball cards.

The fraction line could help you by turning the equivalent fraction into a decimal.

You could write the decimal in tenths as a fraction as 4/10 because there are 10 parts and 0.4 or his cards are baseball cards.

Answer:

61

Step-by-step explanation:

nth=5n+1

.: 12th=5(12)+1 =60+1

=61

Answer:

yes

Step-by-step explanation:

First we find the value of [tex]x[/tex]. This is quite simple as it's a right angled triangle with one of the angles already given. The main concept is vertically opposite angles meaning if 2 lines intersect, the opposite 2 angles are equal.

So the angle [tex]55x - 1[/tex] is for the interior of the triangle too. Now due to angle sum postulate, [tex]36x + 55x -1 + 90 = 180[/tex]

Simplify this and you get: [tex]91x = 91[/tex]

Hence, [tex]x = 1[/tex]

Now, we need to find the value of angle [tex]A[/tex] which is [tex]36x[/tex] which is basically [tex]36 * 1[/tex] when we replace [tex]x[/tex] with [tex]1[/tex].

Henceforth, angle [tex]A[/tex] is equal to [tex]36[/tex] so option [tex]C[/tex] is correct. :D

===================================================

Explanation:

Place point B at the intersection of the lines where the 90 degree angle is located.

Place point C at the other intersection point.

So we have triangle ABC.

Since we have a right angle, this means angle B is 90 degrees.

Angle C is 55x-1 degrees because it's vertical to the angle shown. Vertical angles are congruent.

See the diagram below.

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

From here we use the idea that all three angles of any triangle always add to 180

A+B+C = 180

(36x) + (90) + (55x-1) = 180

91x+89 = 180

91x = 180-89

91x = 91

x = 91/91

x = 1

Use this x value to find angle A and C

A = 36x = 36*1 = 36

C = 55x-1 = 55*1-1 = 54

Finding angle C is optional since your teacher just wants angle A, but it's useful to help check our answer

A+B+C = 36+90+54 = 180

So this confirms we have the right x value.

Recall, Positive/Negative Association: • Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. • Two variables have a negative association when the values of one variable tend to decrease as the values of the other variable increase.

Answer:

y = - 3x + 5

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

3x + y + 2 = 0 ( subtract 3x + 2 from both sides )

y = - 3x - 2 ← in slope- intercept form

with slope m = - 3

Parallel lines have equal slopes, thus

y = - 3x + c ← is the partial equation

To find c substitute (3, - 4) into the partial equation

- 4 = - 9 + c ⇒ c = - 4 + 9 = 5

y = - 3x + 5 ← equation of line in form y = mx + c

The equation of line which parallel to given line is, [tex]y=3x-8[/tex]

The equation of line in slope intercept form is,

                            [tex]y=mx+c[/tex]

Where m is slope of line and c is y-intercept.

Equation of line given that,

                            [tex]y=3x+4[/tex]

So that, slope of line is [tex]3[/tex]

We have to find the equation of the line that passes through (4,4) and is parallel to given lines.

Since, slope of all parallel lines are same.

Equation of required line is,

                          [tex]y=3x+c[/tex]

Substitute point (4,4) in above line.

                        [tex]4=12+c\\\\c=4-12=-8[/tex]

So that, equation of line become,

                       [tex]y=3x-8[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Answer:

1 rose cost $1.5

1 carnation cost $0.5

Step-by-step explanation:

Let the price for one rose be r, price for one daisies be d and the price for one carnation be c

For Ben;

5r + 8d + 2c = 14.5

For Alex

3r + 12d + c = 14

For Joe

10r + d + 3c = 17.25

From equation iii;

d = 17.25- 10r - 3c

Insert this into the first two equations;

5r + 8(17.25-10r-3c) + 2c = 14.5

5r + 138 - 80r -24c + 2c = 14.5

-75r -22c = -123.5

Thus;

75r + 22c = 123.5

Insert the formula for d in the second equation;

3r + 12(17.25-10r-3c) + c = 14

3r + 207 - 120r -36c + c = 14

-117r-35c = 14-207

117r + 35c = 193

So we have two equations to solve simultaneously;

75r + 22c = 123.5

117r + 35c = 193

Multiply first equation by 35 and second by 22

2625r + 770c = 4322.5

2574r + 780c = 4246

Subtract second from first

51r = 76.5

r = 76.5/51

r = 1.5

Insert this in the equation below;

75r + 22c = 123.5

75(1.5) + 22c = 123.5

112.5 + 22c = 123.5

22c = 123.5-112.5

22c = 11

c = 11/22

c = 0.5

Answer:

A

Step-by-step explanation:

Step-by-step explanation: The first thing you're going to probably

try to do here is to factor out a greatest common factor.

The problem is, there is no factor that is in common

to all three of these terms so you may think it's unfactorable.

However, this trinomial is in a special form.

We have an x squared term, an x term, and a constant term.

When a trinomial is in this form, it can be

factored as the product of two binomials.

So start by setting up two sets of parentheses.

Inside each set, we will have the two terms that compose each binomial.

So we have (    )(    ).

The first term is a factor of the x² term, x · x.

For the second term, we need factors of 12 that add to -7.

Since the middle term is negative, we use the negative factors of 12.

Notice that -4 and -3 add to -7 and multiply to be 12.

So our answer is (x - 4)(x - 3).
