Step-by-step explanation:

pop years

3000 0 years

It doubles every decade or 10 years

Multiply the population by 2 and add 10 years

6000 10 years

12000 20 years

24000 30 years

The store salsa jars have a height of ten centimeters and a radius of five centimeters. If there is only four centimeters of sal

Romashka-Z-Leto [24]

Answer:

$V=471.24cm^{3}$ (simplified)

$V=150\pi cm^{3}$ (in terms of pi)

Step-by-step explanation:

Since the salsa jar is basically a cylinder, to solve this we are using the formula for the volume of a cylinder:

$V=\pi r^{2} h$

where

$V$ Is the volume of the cylinder (salsa jar)

$r$ is the radius of the cylinder (salsa jar)

$h$ is the height of the cylinder (salsa jar)

We know from our problem that height of the full salsa jar is 10 centimeters; we also know that that there are only 4 centimeters of salsa left in the salsa jar. So, to find the the height of the missing salsa, we just need to subtract the height of the salsa from the height of the full salsa jar: $h=10cm-4cm=6cm$ . Since the radius of the salsa jar never changes, $r=5cm$ .

Now we can replace the values in our volume formula to find how much salsa is missing from the jar:

$V=\pi r^{2} h$

$V=\pi (5cm)^{2} (6cm)$

$V=\pi (25cm^{2})(6cm)$

$V=150\pi cm^{3}$

$V=471.24cm^{3}$

We can conclude that there are 471.24 cubic centimeters missing from the jar, or in terms of pi: $150\pi cm^{3}$ .

The measure of the supplement of an angle is 60 degrees less than four times the measure of the complement of the angle. Find th

Kisachek [45]

Answer:

Step-by-step explanation:

angle:: x

complemet: 90-x

supplement: 180-x

Equation:

180-x = 4(90-x)+60

180-x = 360 -4x + 60

3x = 240

x = 80 degrees (the angle)

90-x = 10 degrees (the complement)

180-x = 100 degrees (the supplement)

Suppose a triangle has two sides of length 14 and 14, and that the angle between these two sides is 122 degrees. What is the len

Dafna1 [17]

Suppose we have a triangle ΔABC,

Length of AB = 14

Length of AC = 14

Angle ∠BAC = 122 degree

This triangle is isosceles triangle so, angle B = angle C = (180 - 122)/2 = 29

We know the two side and one angle of triangle ABC, here we use Sine Rule.

(In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of a triangle (any shape) to the sines of its angles.)

According to the law,

$\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}$

$\frac{a}{sinA} =\frac{14}{sin29}$

Solve for a

a = 24.49 option C
