What is the best estimation of the equation 7/8 − 6/11? Drag the numbers into the boxes. Numbers may be used once, twice, or not
aniked [119]

Answer:

1 - 1/2 = 1/2

Step-by-step explanation:

These numbers are the best estimation of the equation 7/8 - 6/11 because 7/8 is approximately 1 and 6/11 is approximately 1/2. If you subtract 1 from 1/2 you get 1/2.

If y varies directly as x, and y = 75 when X = 25. Find x when y=21 PLEASE HELP ASAP
user100 [1]
I think x would equal 7 because when y=75 and x=25, x is one third of y so one third of 21 is 7

The angle the golfer went off line from the tee when they  drove the ball

is \phi=28.2 \textdegree because the cosine rule has been applied to calculate the angle

From the question we are told that:

Distance of hole from tee d_h=340yards

Distance to the right d_r=230yards

Ball distance from hole d_b=175 yard

Given that the three points form a triangle x,y,z respectively

Where

d_h=xz

d_r=xy

d_b=yz

Using Cosine Rule

yz^2=xy^2+xz^2-2(xy)(xz)cos\phi

Therefore

cos\phi=\frac{yz^2}{xy^2+xz^2-2(xy)(xz)}

cos\phi=\frac{(175)^2}{230^2+340^2-2(230)(340)}

cos\phi=0.88

\phi=28.2 \textdegree

In conclusion the angle the golfer went off line from the tee when they

drove the ball is mathematically deducted and give as

\phi=28.2 \textdegree

THE GRAPH IS BELOW THANKS :) Anika is on the crew to set up rides for the state fair. The crew does most of the setup on the day
Vaselesa [24]

Answer:

(a) We will form an equation of line from the points given (6,10) and (2,15)

Using:y-y_1=\frac{y_2-y_1}{x_2-x_1}\cdot (x-x_1)

On substituting the values in the formula above we will get the required equation of line.

y-10=\frac{15-10}{2-6}\cdot (x-6)

\Rightarrow y-10=\frac{5}{-4}\cdot (x-6)

On simplification we will get:

y=\frac{1}{4}(-5x+70)

(b) We need to tell at day 0 put x=0 in above equation:

y=\frac{1}{4}(-5\cdot 0+70)

y=70

Anika worked for 70 hours on the set up crew on the day the fair arrived at the fairgrounds day 0.

Now, we need to tell decrease per day which is equal to the slope of line

To find the slope compare the equation with general equation which is y=mx+c where m is slope

Here, in y=\frac{1}{4}(-5x+70)

m=\frac{-5}{4}  which is the decrease per day.
