stealth61 [152]2 years ago

8 0

Answer:

Step-by-step explanation:

y > 0 - the region above the line together with that line

y ≥ 0 - the region above the line together with that line

y < 0 - the region below the line without that line

y ≤ 0 - the region below the line together with that line

We have:

y > 2 - the region above the line together with that line

y ≥ 2x - 3 - the region above the line together with that line

look at the picture

The common part is the solution.

Nerissa paid a total of $8 for 4 packs of pencils she purchased from the convenience store. Let p represent the cost of one pack

BARSIC [14]

Answer: 4*p=8

Step-by-step explanation:

You can use inverse operation to answer this equation.

write out you problem: 4 x p =8
The inverse of multiplication is division
you do 4/4 which gives you one but the 4 will cancel itself out
Do 8/4 which gives you 2
under the equation write p = 2
And be sure to line the p up with the p, the equal sign with the equal sign, and the 2 stays where it is ( which should be already lined up with the 8)

a local high schools cheerleading squad is selling snow cones during lunch to raise money for a national cheerleading competitio

svlad2 [7]

We have:

Volume of cone = 535 cm³ at the maximum
Height of cone= 8cm

We know the formula to find volume of cone is $\frac{1}{3} r^{2} \pi h$

We need to find the radius of the base of the cone
$535= \frac{\pi r^{2}8} {3}$
$535*8= \pi r^{2}$
$\frac{4280}{\pi}= r^{2}$
$r= \sqrt{ \frac{4280}{ \pi} }$
$r=36.9$ to the nearest one decimal place

The width of the opening of the cone is the diameter of the circle. Diameter is twice the radius, hence 2×36.9=73.8 cm

If a cup of coffee has temperature 95∘C in a room where the temperature is 20∘C, then, according to Newton's Law of Cooling, the

muminat

Answer:

61°C

Step-by-step explanation:

Newton's Law of cooling gives the temperature -time relationship has:

T (t) = 20 + 75 е⁻(t/50)-------------------------------------------------------- (1)

where Time is in minutes (min) & Temperature in degree Celsius (°C)

During the first half hour, t = 30 mins

Substituting into (1)

T = 20 + 75 е⁻(30/50)

= 20 + 75(0.5488)

= 20 + 41.16

= 61.16°C

≈ 61°C

Hello!

If you made 3.80 an hour and worked 40 we can multiply these to find the total amount you earned.

3.80 * 40 = 152

You also made 250 in tips so we add that to the total

152+250 = 402
