Answer:
18
Step-by-step explanation:
6 friends times 5 cookies is 30 cookies in total
30 cookies minus 12 cookies already made is 18!
Answer: 18 cookies
Step-by-step explanation:
Tara invites 6 friends, each friend gets 5 cookies.
So, 6 x 5 to find how many cookies are for 6 friends.
6 x 5
= 30 cookies
Tara only has 12 cookies. How much more does she need?
Everyone should get 30 cookies, but there is only 12.
Subtract to find the difference!
30-12=18

The two-sided limit exists as long as the limits from either side also exist and are equal. So to compute the limit, you have to compute the one-sided limits,
[tex]\displaystyle\lim_{x\to0^-}f(x)[/tex]
[tex]\displaystyle\lim_{x\to0^+}f(x)[/tex]
f(x) has a different definition and thus different behavior as x approaches 0 depending on which direction x is approaching 0:
• When x approaches 0 from the left (or from below), you use the definition of f for x < 0, so
[tex]\displaystyle\lim_{x\to0^-}f(x) = \lim_{x\to0}(-x-2) = -2[/tex]
• When x approaches 0 from the right (or above), you use the other definition, so
[tex]\displaystyle\lim_{x\to0^+}f(x) = \lim_{x\to0} \left(\frac x2-2\right) = -2[/tex]
The limits from either side match, so the two-sided limit exists and is also -2.
Han and Leila live 7 miles apart. They decide to start walking toward each other's houses at
the same time. Leila walks at a rate of 2.5 miles per hour and Han walks at a rate of 3 miles
per hour. How long will it take for them to meet?
2.5 + 3 = 5.5 total speed
7miles / 5.5 mph = 1.27 hours
Answer:
1.27 hours
Step-by-step explanation:
The first step in this process would be adding both rates of Leila and Han together. We know Leila walks at 2.5 miles per hour and Han at 3 miles per hour.
[tex]2.5 + 3 = 5.5[/tex]
We got our sum as 5.5, so now we must complete Step 2, which is the final step. We must divide 7 by 5.5.
[tex]7 / 5.5 = 1.2727...[/tex]
1.2727 ≈ 1.27
the answer to the Question is 1.27 hours.

The length of a rectangle is 9 centimeters more than half
the width. Find the length if the perimeter is 60 centimeters.
Answer:
l = 16 cm
Step-by-step explanation:
Let's set the width of the rectangle as "w" and the length of the rectangle as "w/2 + 9".
The perimeter of a rectangle is calculated by adding up the value of all of its side lengths. Therefore, we can find the perimeter using 2l + 2w = P.
We can substitute 60 for P and w/2 + 9 for l.
2(w/2 + 9) + 2w = 602w/2 + 18 + 2w = 60 w + 18 + 2w = 603w + 18 = 603w = 42w = 14Substitute w = 14 into the equation for length l.
l = w/2 + 9 l = 14/2 + 9 l = 16The length of the rectangle is 16 cm.

Answer:
158 cases
Step-by-step explanation:
Given tbe quadratic regression model :
y = -2x^2 + 40x + 8
y = number of cases of a new disease
x = number of years
The predicted number of cases of a new disease in 15 years can be calculated thus ;
Put x = 15 in the equation ;
y = -2(15)^2 + 40(15) + 8
y = - 2 * 225 + 600 + 8
y = - 450 + 600 + 8
y = 158
158 cases

If p(x)=x^2+x+1 and Q(x)=5x^2-1, find the following
1. Q(4)
2.p(-4)
3.p(1/2)
Answer: 1. 79
2. 13
3. 7/4
Step-by-step explanation:
Q(x)=5x^2-1
Q(4)=5(4)^2-1
=5(16)-1
=80-1
Q(4) = 79
p(x)=x^2+x+1
p(-4)=(-4)^2+(-4)+1
=16-4+1
p(-4) =13
p(x)=x^2+x+1
p(1/2)=(1/2)^2+(1/2)+1
=1/4+1/2+1
2+4+8/9
=14/8
p(1/2) = 7/4
A circle has a circumference of 37 millimeters. What is the circle's
radius? Use 3.14 for pi and round your answer to the nearest tenth.
Answer:
5.9
Step-by-step explanation:
To find radius from circumference you need to divide it by pie. So 37 divided by 3.14 is 11.7834394904. This is the diameter. Now divide it by 2, in this case it is 5.89171974522. When you round to the nearest tenth it gives you 5.9. Hope this Helps!

A block of sugar maple wood has a mass of 82.8 g and density of 0.69 g/cm3. The block is a rectangular prism with a length of 5 cm and a width of 4 cm. What is the height of the block of sugar maple?
Answer:
6
Step-by-step explanation:
I believe if you fallow the mathematical process of d=m/v you will get 6
The height of the block of the sugar maple from the rectangular prism is 6 cm.
What is the volume of a rectangular prism?The volume of a rectangular prism signifies the rectangular area enclosed by the prism. The equation used in calculating the formula for a rectangular prism can be expressed as:
V = length × width × height
From the parameters given:
mass of a sugar maple = 82.8 gThe density of the sugar maple = 0.69 g/cm³[tex]\mathbf{Desity = \dfrac{mass}{volume}}[/tex]
[tex]\mathbf{volume = \dfrac{82.8 g }{0.69 \ g/cm^3}}[/tex]
volume = 120 cm³
Using the previous equation for calculating the volume of a rectangular prism, we have:
120 cm³ = 5 cm × 4 cm × height
120 cm³ = 20 cm² × height
height = 120 cm³/20 cm²
height = 6 cm

David drew this diagram of a picture frame he is going to make. Each square represents 1 square inch. What is the area of the picture frame?
Answer:
64 in²
Step-by-step explanation:
Find the area of the larger rectangle first, and then minus the area of the smaller rectangle.
The length of the larger rectangle
= 9-3 = 6 in
The width of the larger rectangle
= 17-1 = 16 in
The area of the larger rectangle
= 6×16
= 96 in²
The length of the smaller rectangle
= 8-4 = 4 in
The width of the smaller rectangle
= 13-5 = 8 in
The area of the smaller rectangle
= 4×8
= 32 in²
The area of the picture frame
= 96-32
= 64 in²

I NEED HELP! Im trying to find the height of a cone. How do I do the problem and can someone explain it step-to-step?
Answer:
first the primerter then the area
Step-by-step explanation:
Answer:
The height of the cone is simple... here are the steps
Step-by-step explanation:
V= 1/3πr²h
V would be 1,398
π would be 3.14
r² 9.2x9.2
so the new equation is 1,398=1/3(3.14)(84.64)h
Now to get h all by itself multiply all in the equation... after divide by 1/3
1,398= whatever number xh
Now divide that whatever number by 1,398 and you find the height.

Un guepardo está persiguiendo a una gacela que corre a 90km/h. Le separa de ella una distancia de 20 m y lleva una velocidad de 97km/h, que mantiene durante 9s. ¿Alcanzará a la gacela?
Answer:
the cheetah traveled 243 m, it could not catch up with the gazelle that traveled 245 m.
Step-by-step explanation:
Given that
Cheetah running at 90 km/h
Separated from a distance of 20 m
Now speed is 97 km/h
The time is 9 seconds
We need to find out whether it would catch up with the gazelle
For Gazelle
90 km = 90 × 1,000 = 90,000 m
1 h = 1 × (60 x 60) = 3600 s
Now
90,000: 3,600 = 25 m / s
For Cheetah
97 Km = 97 × 1000 = 97,000 m
1 h = 1 × (60 × 60) = 3600 s
Now
97 000: 3600 = 26.94 i.e. 27 m/s
e = 27 m /s × 9 s = 243 m
e = 25 m/s × 9 s = 225 m
Now
we have to add 20 m advantage to the gazelle.
So,
= 225 + 20
= 245 m
So based on the above calculation
the cheetah traveled 243 m, it could not catch up with the gazelle that traveled 245 m.
