Answer:

c=a2+b2

use the Pythagorean Theorem

The number of pounds that one of the heaviest bag weighs more than one of the lightest bag in the given line plot is: 1½

In a line plot, frequency of a data point is either represented by a dot or a mark.

In the line plot given:

Heaviest bag weighs 5¾

Lightest bag weighs 4¼

The difference between the heaviest and lightest bag = 5¾  - 4¼

= 23/4 - 17/4

= (23 - 17)/4 = 6/4 = 3/2

= 1½

The heaviest bag weighs 1½ pounds than the lightest bag.

Answer:

Step-by-step explanation:

X/50 = 40/64

To find x cross multiply:

64 * x = 50 * 40

Simplify:

64x = 2000

Divide both sides by 64:

X = 31.25

Answer:

x = [tex]\frac{125}{4}[/tex]

Step-by-step explanation:

[tex]\frac{X}{50}[/tex] = [tex]\frac{40}{64}[/tex]

Divide both sides of the equation by the coefficient of variable

X = [tex]\frac{40}{64}[/tex] x 50

Simplify the fractions:

x = [tex]\frac{5}{4}[/tex] x 25

Write as a single fraction

x = [tex]\frac{5*25}{4}[/tex]

Calculate the product:

x = [tex]\frac{125}{4}[/tex]

Answer:

x = 16

measure of Arc(DE) = 167°

Step-by-step explanation:

Since the arc EFG make a straight angle, we can infer;

180° = Arc(EF) + Arc(FG)

180° = (x-3)° + (12x - 25)°

180° = 13x - 28

208 = 13x

16 = x

Arc GF and DE are vertical angles so if you find the measure of Arc GF then it's the same as measure of Arc DE

mDE = mGF

mDE = 12x - 25

mDE = 12(16) - 25

mDE = 192 - 25

mDE = 167°

Answer: See below

Step-by-step explanation:

Answer (1)

We must break down the expressions into factors. That is:

[tex]\begin{align} \log 12&=\log 4\times 3=\log 2^2\times 3\\ \log 12&=\log 2^2+\log 3=2\log 2+\log 3=2x+y\\ \end{align}[/tex][tex]\log \frac{14}{3}&=\log 14-\log 3 \\ =\log 2\times 7-\log 3\\ \\\log \frac{14}{3}& =\log 2+\log 7-\log 3 \\ =x+z-y\\[/tex]

Answer (2)

[tex]\log 0.3 &=\log \frac{3}{10} \\ \\ =\log 3-\log 10 \\=y-1[/tex]

Answer (3)

[tex]\log 10.5& \\ =\log \frac{21}{2} \\=\log 21-\log 2\\ \\ \log 10.5& \\ =\log 3\times 7-\log 2\\=\log 3+\log 7-\log 2\\=y+z-x[/tex]

If it's a regular nonagon, each exterior angle has measure 360°/9 = 40°, so the supplementary interior angles each have measure 180° - 40° = 140°.

We can split up the nonagon into 9 congruent isosceles triangles whose longer side coincides with the radius of the circle. (The language in the question is a bit ambiguous; I think it's clearler to say the nonagon is itself circumscribed by the circle, so that each of its vertices lie on the circle. See attached image - not mine, but it's in public domain.)

As the image suggests, each triangle will have interior angles measuring 70°, 70°, and 40°.

We can use trigonometry to find the side length of the nonagon, i.e. the length of the shortest side of each triangle - I'll call it x. For example, using the law of cosines,

x² = 4² + 4² - 2 • 4 • 4 cos(40°)   ⇒   x = 4√2 √(1 - cos(40°))

Then the perimeter of the nonagon is

9x = 36√2 √(1 - cos(40°)) in ≈ 24.623 in

The area of a triangle is 1/2 the product of its base and height. The base will be b = x, but to get the height we cut the isosceles triangle in half to produce a right triangle. We use trig again to determine its height h:

tan(70°) = h/(b/2)   ⇒   h = 1/2 x tan(70°)

so each triangle contributes an area of

a = 1/2 bh = 1/4 x² tan(70°) ≈ 5.142 in²

and so the area of the nonagon is

9a = 9x²/8 tan(70°) ≈ 46.281 in²

Answer:

-439

Step-by-step explanation:

Think of the question as s(f(-7))

First replace x with -7 in the equation f(x)= 3x

s(-7) = 3*(-7)

s(-7) = -21

now it is s(-21)

we substitute -21 into the s(x) equation to get [tex]2-(-21)^2[/tex]

That gives you 2-441 = -439

Answer:

$4.50B = C

Step-by-step explanation:

Kenzie bought 12 belts for $54, which means that each belt costs $4.50.

If b=number of belts, c=the total cost, and x=the cost of one belt, the equation would be:

b(x)=c,

so:

12*$4.50=$54

OR

$4.50B=C
