How to estimate 9.1% of 59.3

Mathematics
1 answer:
gavmur [86]4 years ago
7 0

Answer:

6

Step-by-step explanation:

For a quick rough estimate, I'd round 9.1% up to 10% and 59.3 to 60.  10% of 60 is 0.1(60) = 6.

For a more accurate estimate, round 9.1% down to 9% and 59.3 up to 60.  Then 9% of 60 is 5.4.

dybincka [34]

Answer:

While it’s possible to create a dot plot using this data, plotting 50 points on a number line is cumbersome. The more data points there are, the more tedious it is to make a dot plot. For this case, it might be better to use a different visual representation.

At what points does the helix r(t) = sin(t), cos(t), t intersect the sphere x2 + y2 + z2 = 17? (Round your answers to three deci
klasskru [66]

Answer:

the helix intersects the sphere at t=4 and t=(-4)

Step-by-step explanation:

for the helix r(t) = [ sin(t) , cos(t) ,  t ] then x=sin(t) , y=cos(t) and z=t

thus the helix intersect the sphere  x² + y² + z² = 17 at

x² + y² + z² = 17

[sin(t)]²+[cos(t)]²+ t² = 17

1 + t² = 17

t² = 16

t = ±4

thus the helix intersects the sphere at t=4 and t=(-4)

Mrs. Lau rolls out 2 3/4 feet of dough to make noodles. If the noodles are 3/8 of an inch wide, how many noodles will she make?
Law Incorporation [45]

Answer:

7

Step-by-step explanation:

2 3/4=2.75

3/8=0.375

2.75/0.375=7.333333

Since Mrs. Lau cannot make 7.333333 noodles, she can only make 7.

What is the equation of the line that passes through the point (-4,8) and has a slope of -1/4
iragen [17]

Answer:

Step-by-step explanation:

When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.

It is given by:

                      $ (y - y_1) = m (x - x_1) $

where $m$ is the slope of the line and

           $ (x_1, y_1) $ is the point passing through it.

Here, $ m = \frac{-1}{4} $ and $ (x_1,y_1) = (-4,8) $

Substituting in the equation:

$ y - 8 = \frac{-1}{4} (x + 4) $

$ \implies 4y - 32 = -x - 4 $

$ \implies x + 4y - 28 = 0 $
