What is the decimal equivalent of 14/60 ?

Answer:

1,350 square cm

Step-by-step explanation:

As we all know, we have to square a dimension of length to get the dimension of an area

So in this case, since the dimension of the length is increasing by a factor of 3, the dimension of the area will be increasing by a factor which is square the factor by which the dimension of the side is increasing

Thus, we have the area dimension increase by a factor of 3^2 = 9 times the area of the smaller

nonagon

So the area of the bigger nonagon will be :

150 * 9 = 1,350 square cm

Question:

Two red and two blue blocks....

Answer:

[tex]P(Not\ Blue) = \frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]Red = 2[/tex]

[tex]Blue = 2[/tex]

Required

Probability of not selecting blue

First, we calculate the probability of selecting blue

[tex]P(Blue) = \frac{Blue}{Total}[/tex]

[tex]P(Blue) = \frac{2}{2+2}[/tex]

[tex]P(Blue) = \frac{2}{4}[/tex]

[tex]P(Blue) = \frac{1}{2}[/tex]

In probability:

Opposite probabilities sum up to 1 i.e.

[tex]P(Blue) + P(Not\ Blue) = 1[/tex]

This gives

[tex]\frac{1}{2} + P(Not\ Blue) = 1[/tex]

[tex]P(Not\ Blue) = 1 - \frac{1}{2}[/tex]

[tex]P(Not\ Blue) = \frac{2-1}{2}[/tex]

[tex]P(Not\ Blue) = \frac{1}{2}[/tex]

Step-by-step explanation:

According to the question, Johnson used 2 2/3 tanks of gas in 2 1/2 days Thus;

If 8/3 tanks of gas were used in 5/2 days,

Then in 1 day , 5/2 × 3/8 = 15/16 or 0.9 tanks were used per day

Answer:

The solution to the quadratic equation be:

[tex]x=\frac{5}{3},\:x=-1[/tex]  

Step-by-step explanation:

Given the expression

3x² – 2x = 5

Solving with the quadratic formula

[tex]3x^2-2x=5[/tex]

subtract 5 from both sides

[tex]3x^2-2x-5=5-5[/tex]

Simplify

[tex]3x^2-2x-5=0[/tex]

For a quadratic equation of the form ax²+bx+c=0

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

For a = 3, b = -2, c = -5

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \sqrt{\left(-2\right)^2-4\cdot \:3\left(-5\right)}}{2\cdot \:3}[/tex]

[tex]x_{1,\:2}=\frac{-\left(-2\right)\pm \:8}{2\cdot \:3}[/tex]

Separate the solutions

[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3},\:x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]

solving

[tex]x_1=\frac{-\left(-2\right)+8}{2\cdot \:3}[/tex]

    [tex]=\frac{2+8}{2\cdot \:3}[/tex]

    [tex]=\frac{10}{6}[/tex]

    [tex]=\frac{5}{3}[/tex]

also solving

[tex]x_2=\frac{-\left(-2\right)-8}{2\cdot \:3}[/tex]

    [tex]=\frac{2-8}{2\cdot \:3}[/tex]

    [tex]=\frac{-6}{2\cdot \:3}[/tex]

    [tex]=\frac{-6}{6}[/tex]

     [tex]=-\frac{6}{6}[/tex]

     [tex]=-1[/tex]

Therefore, the solution to the quadratic equation be:

[tex]x=\frac{5}{3},\:x=-1[/tex]

Answer:

32

Step-by-step explanation:

So since you can see that two of the sides are equal, that means the 2 angles at the bottom of the triangle are both equal to 25. Since the interior angles in a triangle always add up to 180, so it would be:

25 + 25 + 4x + 2 = 180

Solving,

52 + 4x = 180

subtract 52 from both sides

[tex]4x = 128[/tex]

divide both sides by 4

[tex]x = 32[/tex]°

hope that makes sense!

Answer:

x = 32

Step-by-step explanation:

the tic marks on the two sides of the triangle indicate they are congruent; therefore the two base angles are congruent also - each is 25°.

so, we can set up this equation to solve for 'x':  25 + 25 + 4x + 2 = 180

52 + 4x = 180

4x = 128

x = 32

Answer:

43

Step-by-step explanation:

Let x=lucy and y=chuck

we know that in total they found 92 arrowheads which means that

x+y=92

we also know that lucy found 6 more than chuck which means taht

x-6=y

Let's solve this through substitution

Looking at the second equation we know exactly what y is equal to in terms of x so we can plug this in (x-6) whenever we see a y in the first equation

so we have

x+(x-6)=92

solve for x and get

2x=98

x=49

Now that we know what x is equal to we can solve for y

49-6=y

y=43

This means that lucy found 49 and chuck found 43

Answer:

$3,072

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 32000 × 0.032 × 3 = 3072

I = $ 3,072.00

The simple interest accumulated

on a principal of $ 32,000.00

at a rate of 3.2% per year

for 3 years is $ 3,072.00.

Answer:

The unknown number = 11

Step-by-step explanation:

Let

The unknown number = x

9 times a number is increased by 30

= 9x + 30

140 is decreased by the number

= 140 - x

9x + 30 = 140 - x

Collect like terms

9x + x = 140 - 30

10x = 110

x = 110 / 10

x = 11

Check:

9x + 30

9(11) + 30

= 99 + 30

= 129

140 - x

= 140 - 11

= 129

Answer: The measure of angle P = 29°

Step-by-step explanation:

We can find the interior supplementary angle at Q by subtracting

180- 56 = 124

The sum of the interior angles must be 180, so we can add ∠Q + ∠R

124 + 27 = 151

Then subtract that from 180:

P = 180 - 151

P = 29°

Answer:

34.134%

Step-by-step explanation:

Given :

Normal distribution ;

Mean, m = 100 ; Standard deviation, s = 10

Percentage score between 90 and 100

P(90 ≤ x ≤ 100)

Recall : Zscore = (x - m) / s

P[(90 - 100) / 10 ; (100 - 100) / 10]

P[(10/10 ; 0 / 10)]

P(Z ≤ 1) - P(Z≤0) (Using Z probability calculator)

0.84134 - 0.5

= 0.34134

= 0.34134 * 100%

= 34.134%

Answer:

-3/5

Step-by-step explanation:

Slope is calculated with the formula m=(y_2 - y_1)/(x_2-x_2). The starting point I put as (0,0) and the finish is (5,-3). I used one city block is equal to one. Thus 3 blocks south(y-axis), is -3 and 5 east(x-axis) is 5. So plug into the equation with y_2 as -3 and x_2 as 5 then y_1 and x_1 both as zero. Thus slope=m= -3/5.
