mr Goodwill [35]

Answer:

10 players

Step-by-step explanation:

so  a percentage is really just like a fraction or decimal so were going to turn it into a decimal by moving the decimal point two places to the left making it .20 then to figure out the answer we're going to multiply 50 by .20 to get 10

Need help presenting this solution on and number line and in interval notation. (I’m absolutely clueless haha)
beks73 [17]

Since the number is a fraction make a number line using fractions. The inequality sign includes being equal to, so add a solid dot on -5/2 and since x is less than that, draw an arrow pointing to the left.

See attached drawing.

For interval notation since x can be any number less than or equal to -5/2 it would be written as (-∞, -5/2]

The answer and how you got the answer
olasank [31]

Answer:

\frac{34}{15}

Step-by-step explanation:

we are asked to evaluate

4\tfrac{1}{4}÷1\tfrac{7}{8}

Above we are given mixed fraction which can be converted in proper fraction using formula given below

a\tfrac{b}{c}=\frac{a \times c +b}{c}

Hence

4\tfrac{1}{4}=\frac{4 \times 4 +1}{4}

4\tfrac{1}{4}=\frac{17}{4}

Also

1\tfrac{7}{8}=\frac{1 \times 8 +7}{8}

1\tfrac{7}{8}=\frac{15}{8}

Hence

4\tfrac{1}{4} ÷ 1\tfrac{7}{8}

can be written as

\frac{17}{4} ÷ \frac{15}{8}

Also we know the rule for dividing fraction is as given below

\frac{a}{b} ÷ \frac{c}{d} = \frac{a}{b} \times \frac{d}{c}

Hence

\frac{17}{4} ÷ \frac{15}{8} = \frac{17}{4} \times \frac{8}{15}

=\frac{17 \times 2}{15}

=\frac{34}{15}

Use the right triangle and the given information to solve the right triangle.
Leni [432]

Answer:

a= 4.993

c = 5.824

A= 59°

C = 90°

Step-by-step explanation:

b=3, B=31°

Since it's a right angle.

C = 90°

A = 180-90-31

A= 59°

For side a and c

a/sin A = b /sin B

a = sinA * b/sin B

a= sin 59 * 3/sin31

a= 4.993

a = 5

c/sin C = b/sin B

c = sin C * b/sin B

c = sin90 * 3/sin 31

c = 1* 5.824

c = 5.824
