Answer:

g(q) = 5/8q

Step-by-step explanation:

-7q + 12r = 3q - 4r

Add 4r to each side

-7q + 12r+4r  = 3q - 4r+4r

-7q +16r = 3q

Add 7q to each side

-7q+7q +16r = 3q+7q

16r = 10q

Divide each side by 16

16r/16 = 10q/16

r = 5q/8

g(q) = 5/8q

Answer:

About 78.1 square centimeters

Step-by-step explanation:

First, you need to find the areas of each individual shape, and then to subtract  one from the other. The area of the circle is [tex]\pi r^2=\pi \cdot 6^2\approx 113.1[/tex]. The area of the rectangle is [tex]7\cdot 5=35[/tex]. Subtracting this from the area of the circle, you get about 78.1 centimeters. Hope this helps!

Answer:

[tex]78.09 {cm}^{2} [/tex]

Step-by-step explanation:

First find the area of the circle

[tex]\pi {r}^{2} \\ \pi \times 6 \times 6 \\ = 113.09[/tex]

Now find the area of the rectangle

[tex]b \times h \\ = 5 \times 7 \\ = 35[/tex]

Now subtract the area of the rectangle from the area of the circle.

You'll get the area of the shaded region.

[tex]113.09 - 35 \\ = 78.09 {cm}^{2} [/tex]

Answer:

0.15%

Step-by-step explanation:

The Empirical Rule ( 68-95-99.7 Rule) states that almost all data falls within 3 standard deviations of the mean for a normal distribution.  Under the rule:

Given that:

mean (μ) = 594 and standard deviation σ = 96

The percentage of people that all fall outside 306 and 882 = 100% - 99.7% = 0.3%. Therefore the percentage of people that are below 306 = 0.3% / 2 = 0.15%

Answer:

42°

Step-by-step explanation:

We can see that in one leg of the right triangle we already have a 132 degree obtuse angle given. And since a line is 180 degrees, we can see that the inner acute angle of the right triangle is 180 - 132 = 48 degrees.

And since 3 angles of a triangle adds up to become 180, we can use standard algebra to find: 180 - 90 - 48 = 42 degrees.

Answer:

Step-by-step explanation:

Yes, the two angles are congruent.  There are two triangles here, and these triangles are congruent as well.

Answer:

a) 35

Step-by-step explanation:

k^2 = m^2 + j^2 - 2(m)(j) cosK

k^2 = 21^2 + 28^2 - 2(21)(28)(cos90)

k^2 = 441 + 784 - 2(588)(0)

k^2 = 1225 - 0

k^2 = 1225

Answer:

7(3x+5)

Step-by-step explanation:

When factoring out the GCF you want to find the largest number that can divide into both 21 and 35. The largest number is 7 so you divide 7 from 21e and 35.

Answer:

7(3e+5)

Step-by-step explanation:

Answer:

a. 28.

b 20.78.

Step-by-step explanation:

a. f(x) = 0.001(x -  10)(x + 20)(x - 40)

When x = 50

Height = f(40) = 0.001(50-10)(50+20)(50-40)

= 0.001(40*70*10)

= 0.001 * 28,000

= 28 units.

b.

Expanding the function we get

f(x) = 0.001(x  - 10)(x^2 - 20x - 800)

f(x) = 0.001(x^3 - 30x^2 - 600x + 8000)

f(x) = 0.001x^3 - 0.03x^2 - 0.6x + 8

Finding the derivative

f'(x) = 0.003x^2 - 0.06x - 0.6

This is zero for maxm/minm values:

0.003x^2 - 0.06x - 0.6 = 0

x = 27.32, - 7.32.

The values of the heights corresponding to these values of x are:

0.001(27.32-10)(27.32+20)(27.32-40)

= -10.39. and

0.001(-7.32-10)(-7.32+20)(-7.32-40)

= 10.39.

So the distance between A and B =  10.39 - (-10.39)

= 20.78.

Answer:

1149.8 m³

Step-by-step explanation:

The volume (V) of a sphere is calculated as

V = [tex]\frac{4}{3}[/tex]πr³ ( r is the radius )

Here diameter = 13, thus radius = 13 ÷ 2 = 6.5

V = [tex]\frac{4}{3}[/tex] × 3.14 × 6.5³

   = [tex]\frac{4}{3}[/tex] × 3.14 × 274.625

   = [tex]\frac{4(3.14)(274.625)}{3}[/tex] ≈ 1149.8 m³ ( to the nearest tenth )

Answer:

Step-by-step explanation:

(2/3) - (5/6) = (-1/6)

(-1/6)/(3/4) = -2/9

The value of the expression is -4/18

According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.

Given here, the expression as (2/3-5/6) / 3/4 = 4-5 /6 × 4/3

                                                                          = -4/18

Hence, the value of the expression is  -4/18

Answer:

B. 5 cm3

Step-by-step explanation:

The volume of the oblique pyramid with a square base is 3.33 cm³.

Suppose the base of the pyramid has length = l units, and width = w units.

Suppose that the height of the pyramid is of h units, then:

[tex]v = \dfrac{l \times w \times h}{3} \: \rm unit^3[/tex]

is the volume of that pyramid.

The base is a rectangle with length = L units, and width = W units, so its area is:

[tex]b = l \times w\: \rm unit^2[/tex]

We are given that;

the base is about 2 cm long and that the height is about 2.5 cm long.

Now,

Using these values, we can estimate the volume as:

V ≈ (1/3) × Base Area × Height

V ≈ (1/3) × (2 cm)² × 2.5 cm

V ≈ (1/3) × 4 cm² × 2.5 cm

V ≈ 10/3 cm³

V ≈ 3.33 cm³

Therefore, an approximate volume of the pyramid will be 3.33 cm³.

Step-by-step explanation:

Find the mean of the 2 given values

mean = [tex]\frac{25+9}{2}[/tex] = [tex]\frac{34}{2}[/tex] = 17

Noe find the mean of 25 and 17 and 17 and 9

mean = [tex]\frac{25+17}{2}[/tex] = [tex]\frac{42}{2}[/tex] = 21 and
