V=vanila
c=chocolate

4v+1c=45
v+c=27

mulitply 2nd equation by -1 and add to top one

-v-c=-27
4v+1c=45 +
3v+0c=18

3v=18
divide by 3
v=6

sub back
v+c=27
6+c=27
c=21

21 choc and 6 van





A.
v+c=27
4v+1c=45
v=number of vanila wafers bought
c=number of chocolate wafers bought

B. 21 chocolate and 7

Analyze the diagram below and complete the instructions that follow. / Find the surface area of the composite solid if the base is a regular hexagon. Round your answer to the nearest hundredth. A. 471.53 m2 B. 615.53 m2 C. 709.06 m2 D. 802.59 m2

According to the image:
the right hexagonal pyramid surface area is given by the following formula:

S = 3√3 / 2) a² + 3a √h²+3a²/4
a = the base edge
h = the height of the pyramid

looking at the image  a =6m,  h =21m - 7m= 14m

so the surface area is S = 3√3 / 2) 6² + 3*6√14²+3*6²/4 =93.53+ 14.93=108.46 m²

for the another one
the figure is a prism hexagonal
its surface area is 
SA= 6ah +3√3 a²
a= base edge, h =height
in our case a =6m and h = 7m
so SA= 6*6*7 + 3√3 * 6²= 252 + 187 = 439 m²

finally, the surface area of the complete image is 
ST= S + SA = 108.46 m² + 439 m² = 547.52 m²
it is so approximate
 to B. 615.53 m2
look at the image

A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of ___. 5 √(13) √(97)

Answer:

A parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal of √(13) units.

Step-by-step explanation:

RSTU is parallelogram. The vertices of the parallelogram are R(1, -1), S(6, 1), T(8, 5), and U(3, 3).

Two opposite vertices are connected by the diagonal of a parallelogram. So, RT and SU are two diagonal.

Distance formula:

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Using this formula we get

RT=\sqrt{(8-1)^2+(5+1)^2}=\sqrt{49+36}=\sqrt{85}

SU=\sqrt{(3-6)^2+(3-5)^2}=\sqrt{13}

Therefore the parallelogram whose vertices have coordinates R(1, -1), S(6, 1), T(8, 5), and U(3, 3) has a shorter diagonal SU of √(13) units.

Which set of integers is a Pythagorean triple? 3, 5, 6 5, 12, 13 15, 9, 17 6, 8, 12

Answer:

The set of integers which form a Pythagorean triple is:

5,12,13

Step-by-step explanation:

We are asked to find the set of integers such that they form a Pythagorean triplets.

Three integers a,b,c are said to form a Pythagorean triplets if they satisfy the property:

c^2=a^2+b^2

1)

3,5,6

6^2=36

and

3^2+5^2=9+25\\=34\neq 36

Hence option: 1 is incorrect.

2)

5, 12, 13

13^2=169

and

5^2+12^2=25+144=169

This means:

13^2=5^2+12^2

Hence, option 2 is correct.

3)

15,9,17

17^2=289

Also,

15^2+9^2=225+81=306\neq 289

Hence, option 3 is incorrect.

4)

6,8,12

12^2=144

and:

6^2+8^2=36+64=100\neq 144

Hence, option 4 is incorrect.

Graph the pH function using the graphing utility. Then answer the questions. What is the pH of lemon juice that has a hydrogen ion concentration of 0.01 moles per liter? The pH is??

Answer:

pH = 2

Step-by-step explanation:

To graph the pH function :

The range of the pH function varies from 1 to 14

And the concentration of hydrogen ion goes from 0 to 1

Taking pH value on y-axis and concentration of hydrogen ion on x-axis, The resultant graph is attached below :

Given : Concentration of hydrogen ion = 0.01

Now, pH = -log(0.01)

pH=-\log(\frac{1}{100})\\\\pH=-(\log 1 - \log 100)\\pH=-(0-2)\\\implies\bf pH=2

If a+b+c=-9, and x+y=8, what is -4a+6x-4c+6y-4b

Hey there! 

For this problem, you can go ahead and split up your equation to replicate the format that you've been provided in your first two equations.

–4a + 6x – 4c + 6y – 4b

a + b + c = (–9)
–4a – 4b – 4c = –4(–9)
–4a – 4b – 4c = 36

x + y = 8
6x + 6y = 6(8)
6x + 6y = 48

If you don't understand what I just did, consider what I have below (this is not part of your problem, this is just so you can understand how I got the answers for the individual equations above):

x = 6
2x = 2(6) = 12
3x = 3(6) = 18, etc...

So, your big equation should be equal to 48 + 36, which is 84. 

–4a + 6x – 4c + 6y – 4b = 84

Hope this helped you out! :-)

How do you do a 3-step algebra equation?

The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a         -3a
_______________
3a + 6 = 15

Now it's a 2 step equation and you solve it on from there.
