Answer:

10/3 and 23/4

Step-by-step explanation:

Answer:

9 1/12

Step-by-step explanation:

3 1/3 + 5 3/4

Get a common denominator of 12

3   1/3*4/4 +  5  3/4 *3/3

3 4/12 + 5 9/12

8 13/12

8 + 12/12 + 1/12

8+1+1/12

9+1/12

9 1/12

Changing to improper fraction

3 1/3 = ( 3*3+1)/3 =10/3

5 3/4 = ( 4*5+3)/5 =23/4

Getting a common denominator

10/3 * 4/4 = 40/12

23/4 *3/3 =69/12

                   -------------

                   109/12

12 goes into 109  9 times

9*12 = 108  and that leaves 1 left over

9 1/12

Answer: 68 adult tickets were sold and 78 child tickets were sold.

Step-by-step explanation:

a + c = 146 where a is the number of adults tickets sold and c is the numbe rof child tickers sold.

5.60 a+ 8.80c= 1067.20

    a    + c = 146

5.60a  + 8.80c = 1067.20 solve by elimination.

a=68

c =78

Step-by-step explanation:

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The slope of the given equation of the line is 0.2.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c, slope intercept form

y - y₁ = m(x - x₁), point-slope form

where,

x and x₁ are the coordinates of the x-axis,

y and y₁ are the coordinates of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The equation of a line in the point-slope form is y–9=(1/5)(x-2). Therefore, the slope of the line is (1/5).

Answer:

downward, maximum value

Step-by-step explanation:

f(x) = - x^2 - 3x + 1

The negative in front of the x^2 means the graph opens downwards

The y intercept is 1

Because it opens downward it has a maximum value

Answer:

Opens downwards and has a maximum value

Step-by-step explanation:

f(x) = -x² - 3x + 1

a is the coefficient of x², which is -1

Since a < 0, it's a concave down graph which opens downwards. Therefore it has a maximum turning point

Answer:

20 cents per unit

Step-by-step explanation:

Since it is 1$ 5 pencils and 100/5=20, the unit cost is 20 cents

Answer:

the unit price is $0.20 for 1 pencil

Step-by-step explanation:

if u see 5 pencils cost 1 dollars and unit price means the value of one item, so like the cost of 1 pencil

write it as a ration of cost to pencil

the ratio is 1/5

now divided 5 on the top and the bottom to get the unit price

1 divided by 5= 0.2

so now the ratio is 0.2/1

Answer:

12/20

or

3/5

or

0.6

Step-by-step explanation:

The probability that a student chosen randomly from the class plays basketball or baseball is 3/5.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Total student = 20

let the number who play both = x

So, Number of those who play basketball = 8- x

and, Number of those who play baseball = 8- x

Number of those who played neither = 8

So, 8-x + 7- x + x + 8 = 20

x = 3

Then, Basketball player = 8-3 =5

and, baseball player = 7-3 = 4

Thus, the probability that a student chosen randomly from the class plays basketball or baseball

= (5+ 4 + 3)/ 20

= 12/20

= 3/5

Answer:

x=6

Step-by-step explanation:

We can use ratios to solve

18              4x+6

--------- = -------------

24               40

Using cross products to solve

18*40 = 24 * (4x+6)

720 = 24*(4x+6)

Divide each side by 24

720/24 = 24/24 (4x+6)

30 = 4x+6

Subtract 6 from each side

30-6 = 4x+6-6

24 = 4x

Divide each side by 4

24/4 = 4x/4

6 = x

Answer:

x=30

Step-by-step explanation:

Sin 60 = ((√3)/2), so x=90-60. x=30.

The required value of x for function sin(90°– x)= - √3/2 is x =150°.

A function is given as sin(90°– x)= - √3/2, Value of x for the function is to be determined.

The equation contains trigonometric operators such as sin, cos.. etc. In algebraic operation.

sin(90°– x)= - √3/2
sin(90°– x) = -sin60
90°-x = sin(-60°)
90°-x = -60°
-x = -60°-90°
x = 150°

Thus, the required value of x for function sin(90°– x)= - √3/2 is x =150°.

The secant is the distance from the center to the vertical tangent in a certain direction.

Answer:

A. secant

Step-by-step explanation:

For trigonometric ratios, we know that cosine is [tex]\frac{adjacent}{hypotenuse}[/tex]. The reciprocal of something is just flipped over. So the reciprocal of cosine is [tex]\frac{hypotenuse}{adjacent}[/tex], which is the ratio for secant.

Another way we can remember this is       [tex]sec x = \frac{1}{cos x} \\\\cos x = \frac{1}{sec x}[/tex]
