Answer: d) 0.9693

<u>Step-by-step explanation:</u>

refer to the z-table attached.

The table shows the percent from the MEAN. The percent below the mean is 50% so that needs to be added to the value in the table.

Look on the left side for 1.8 and the top for 0.07 (which is 1.87).

The value is 0.4693 --> add 0.5 to that value to get 0.9693.

A brace for a shelf has the shape of a right triangle. Its hypotenuse is 10 inches long and the two legs are equal in length. Ho

vagabundo [1.1K]

This is a classic example of a 45-45-90 triangle: it's a right triangle (one angle of 90) & two other sides of the same length, which means two angles of the same length (and 45 is the only number that will work). With a 45-45-90 triangle, the lengths of the legs are easy to determine:
45-45-90
1-1-sqrt2
Where the hypotenuse corresponds to sqrt2.
Now, your hypotenuse is 10.
To figure out what each leg is, divide 10/sqrt2 (because sqrt2/sqrt2 = 1, which is a leg length in the explanation above).
Problem: you can't divide by radicals. So, we'll have to rationalize the denominator:
(10•sqrt2)/(sqrt2•sqrt2)
This can be rewritten:
10sqrt2/sqrt(2•2)
=10sqrt2/sqrt4
=10sqrt2/2
=5sqrt2 Hope this helps!!

Solve each equation.

Nostrana [21]

Answer:

13x+9=30

13x=30+9

13x=39

divide both sides by 13

x=3

12x+1=-13

12x=-13-1

12x=-14

divide both sides by 12

x=7/6

x+2+4=11

x+6=11

x=11_6

x=5

which has greater cenetic energy a car traveling 30.0 km/hr or one twice as heavy traveling at 15 km/hr?

iVinArrow [24]

Answer:

30 km/h car

Step-by-step explanation:

From analysis the car traveling at 30 km/h has greater kinetic energy

we can deduce it from the expression of kinetic energy which is

$KE=\frac{1}{2} mv^2$

Assuming the mass m= 1 kg

For the 30 km/h

$KE=\frac{1}{2}*1*30^2 \\\\KE=\frac{1}{2}*1*900\\\\\KE=450 J$

For the 15 km/h

$KE=\frac{1}{2}*2*15^2 \\\\ KE=\frac{1}{2}*2*225 \\\\\ KE=\frac{1}{2}*450 J\\\\\ KE=225 J$

Though the kinetic energy is a function of mass and velocity, but from our analysis the faster moving object has more KE
