Answer:

4.8 points per minute

Step-by-step explanation:

Total points = 28

Time taken = 5⅚ minutes = 35/6 minutes

Points per minute = Total points ÷ Time taken

= 28 ÷ 35/6

= 28 × 6/35

= 28 × 0.17143

= 4.8

Help giving medals find the area of the triangle with the given measurements. round the solution to the nearest hundredth if nec

FromTheMoon [43]

In order to solve for the area of the triangle with the given dimensions, we use the equation

A = ac(cos b)/2

Substituting the known values,

A = (11 cm)(18 cm)(cos 104o)/2 = 23.95 cm2

Thus, the answer is the third choice.

HELPPP frenss!!! HURRY j

Answer:

(2, -7)

x = 2

y = -7

Step-by-step explanation:

Let's solve this system of equations by elimination.

Start by multiplying the first equation by 2:

$2(4x)+2(3y)=2(-13)\\8x+6y=-26$

Next, multiply the second equation by 3:

$3(-5x)+3(2y)=3(-24)\\-15x+6y=-72$

Notice that both equations now have a "6y", meaning we can subtract both equations and thereby eliminating the variable "y" from the equation:

$8x+6y-(-15x+6y)=-26-(-72)\\8x+6y+15x-6y=-26+72\\23x=46$

Divide both sides by 23

$x=2$

Substitute 2 for "x" to solve for "y".

$4x+3y=-13\\4(2)+3y=-13\\8+3y=-13$

Subtract 8 from both sides:

$3y=-21$

Divide both sides by 3:

$y=-7$

Therefore the answer is:

$(x, y)=(2, -7)$

Additional Comments:

Note that we can only divide, subtract, multiply, or add both sides of the equation by the same quantity due to the Division, Subtraction, Multiplication, or Addition Property of Equality. These properties state that if you divide/subtract/multiply/add one side of the equation by one quantity, you must do the same to the other side of the equation so that it remains an equation.

Will give brainliest! Help me solve this logs problem!! Thank you

Answer:

Step-by-step explanation:

solving equation 1

log125 base 5√5=x
[5√5=√(25×5)=√125]
log125 base 125=x
[From one of the principles of logarithm " logA base a =1]
therefore, log125 base 125=1
x=1

solving equation 2

log 64 base 2√2=y
[2√2=√(4×2)=√8]
log 64 base√8=y
64=(√8)^y
64=8^(½y)
8²=8^(½y)
(8 cancels in both equations and I evaluate the powers figures)
2=½y
y=2×2=4

the product of x and y=x•y=1×4=4
