Step-by-step explanation:

Answer:

x = 49 mi/hr

y = 6 mi/hr

Step-by-step explanation:

A motorboat travels 258mi in 6 hours going upstream. It travels 330mi going downstream in same amount of time. What's the rate of the boat in still water and what is the rate of the current.

Let

x = the speed of the boat in still water.

y = the speed of the stream

The speed upstream is x - y

The speed downstream is x + y

Distance = rate × time

258 = (x - y)6 (1)

330 = (x + y)6 (2)

From (1)

x - y = 43 (3)

From (2)

x + y = 55 (4)

x - y = 43 (3)

x + y = 55 (4)

Add the equations to eliminate y

x + x = 43 + 55

2x = 98

x = 98/2

x = 49 mi/hr

Substitute x = 49 into (4)

x + y = 55 (4)

49 + y = 55

y = 55 - 49

y = 6 mi/hr

Answer:51.5 degree

Step-by-step explanation: Since DEF is an isosceles triangle, angle D and F needs to be equal. So substract 77 from 180 and divide by 2.

Answer:

Step-by-step explanation:

let angle D and angle F be x

x+x+77=180 degree(being sum of the interior angle of a triangle)

2x=180-77

x=103/2

x=51.2 degree

both angle D and F are 51.2 degree because the base angles of an isosceles triangle are equal.

Answer:

5/12

Step-by-step explanation:

Given

Fraction of punch that is pineapple juice = 1/4

Fraction of punch that is orange = 1/6

Taking the sum;

fraction of the punch that is pineapple juice or orange juice = 1/4 + 1/6

fraction of the punch that is pineapple juice or orange juice = 3+2/12

fraction of the punch that is pineapple juice or orange juice = 5/12

Hence the fraction of the punch that is pineapple juice or orange juice is 5/12

Answer:

Step-by-step explanation:

Using the distance formula, d = (x2 - x1)2 + (y2 - y1)2 we can find that each side is 5 units and there are 6 sides. The perimeter is 5×6 = 30 units.

Answer:

12pi

Step-by-step explanation:

Use the equation for volume:

pi(r^2)*h/3

pi*(2^2)*(9/3)

pi*4*3

12pi

Answer:

the third choice

Step-by-step explanation:

I haven't done those questions in a long time so I would double check. But I think its choice C because 0 has two functions, and I'm pretty sure that a number can only have 1 output, therefore C is not a function..

Step-by-step explanation:

Answer:

300in²

Step-by-step explanation:

l= 12

w= 9

h= 2

Substitute into the equation

S= 2(lw+ wh + hl)

S= 2( 12x9 + 9x2+ 12x2)

S= 2( 108+ 18 + 24)

S= 2( 150)

S= 300

slope of line is 2 comparing equation y= mx+c where m is your slope

Answer:

- 1

Step-by-step explanation:

SLOPE/Y-INTECEPT EQUATION

y = mx + b

The "b" is the slope. Any number that is not multiplied by "x" and is not "y" is the slope.

y = 2x - 1

Since the "-1" is not multiplied by "x" and is not "y", then that means it can only be the slope.

Answer:

[tex] x < - \frac{11}{2} [/tex]

Step-by-step explanation:

Distribute 2 through the parentheses:

[tex]8x + 2 < 3(2x - 3)[/tex]

Distribute 3 through the parentheses:

[tex]8x + 2 < 6x - 9[/tex]

Move the variable to the left-hand side and change its sign:

[tex]8x + 2 - 6x < - 9[/tex]

Move the constant to the right-hand side and change its sign:

[tex]8x - 6x < - 9 - 2[/tex]

Collect like terms:

[tex]2x < - 9 - 2[/tex]

Calculate the difference:

[tex]2x < - 11[/tex]

Divide both sides of the inequality by 2:

[tex]x < - \frac{11}{2} [/tex]

Answer: 14x^2-93xy+60y^2 Hope that helps!

Step-by-step explanation:

1. Expand by distributing terms

(20x-12y)(x-4y)-(3x-4y)(2x+3y)

2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd

20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)

3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd

20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)

4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2

5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)

6. Simplify.

And your answer would be 14x^2-93xy+60y^2

Solution

Order of operations

Answer:

1, 2, 3

Step-by-step explanation:

X <= 20 means that x has to be less than OR equal to 20.

The first option is -100. That's less than 20, so this statement is true.

The second option is 10. That's also less than 20, so this statement is also true.

The third option is 20. This is equal to 20, so this is also true.

The fourth option is 21, which is greater than 20, so it's not true.

The fifth option is 45, which is greater than 20, so it's not true.

Sorry I answered so late, hope this helps even though you probably don't need it anymore.

Answer: x = 46

Step-by-step explanation: 20 + (5 + 7) = x - 14, 20 + (12) = x - 14

Answer:

[tex]x=46[/tex]

Step-by-step explanation:

[tex]20 + (5+7)=x-14[/tex]

[tex]20+12=x-14[/tex]

[tex]32=x-14[/tex]

Take [tex]x-14[/tex] on the other side of the 'equal to' sign and 32 on the other side so that the variable remains on the right side

[tex]x-14=32\\[/tex]

[tex]x=32+14[/tex]

[tex]x=46[/tex]
