You are buying salsa at the grocery store. You have a manufacturer’s coupon for $0.50 off and the store is offering 50% off if you buy 2 containers. One container of salsa costs $3.25. What is your final cost?

Answers

Answer 1

3.25*2 = 6.5*0.5 = 3.25-0.50 = $2.75

Answer 2

Answer: Final cost will be $2.75.

Step-by-step explanation:

Since we have given that

Cost of salsa container = $3.25

Off on coupon = $0.50

Final cost of one salsa container is given by

[tex]3.25-0.50\\\\=\$2.75[/tex]

Hence, the final cost will be $2.75.

if he bought two containers

Cost of two containers is given by

[tex]3.25\times 2\\\\=\$6.50[/tex]

Coupon 50% off is given by

[tex]6.50\times 0.5\\\\=3.25[/tex]

So, Final cost is given by

[tex]6.25-3.25-0.5\\\\=\$2.75[/tex]

Hence, Final cost will be $2.75.

Suppose you want to buy a bike. The prices are $119, $139, $149, $179, $189, $199, and $209. You want the bike that costs $189. Should you use mean, median, or mode to convince your parents? Explain.

Answers

For mean:
119 + 139 + 149 + 179 + 189 + 199 + 209 = 1183
1183/7 (for the amount you added) = 169

For median:

119, 139, 149, 179, 189, 199, 209.
Find the middle number: 179 (is your median)

For mode:

119, 139, 149, 179, 189, 199, 209
Find the number that shows up the most: N/A (they all only show up once)

I believe Median will be your best choice (it has the closest answer to 189)

2. A rectangular garden has a length of 8 ft and a width of 4 ft. A smaller garden was made, using a scale factor of 34 . Find the dimensions of the smaller garden. Enter your answers in the boxes.

Answers

1. You can find the scale factor bookshelf by dividing the actual length with model length.
If you put it into an equation, it would look like this

actual length= model length * scale factor
5ft= 3ft * scale factor
scale factor = 5ft/3ft= 1.667 times

2. You can solve this problem with equation used above. Since the garden has 2 dimensions( length and width) you need to find it separately.

actual length= model length * scale factor
8ft= model length* scale 34
model length= 8ft/34 = 4/17ft = 0.23529 ft

actual width= model width* scale factor
4ft= model width* scale 34
model width= 4ft/34= 2/17ft =0.11764 ft

Answer:

3 / 5 = 0.6 so the scale factor is 0.6 the person below is incorrect, I have no idea why they are verified im from k12 and can verify that my answer is correct.

The table shows the electric current produced by a solar cell in different amounts of sunlight (light intensity). Answer the questions using the data. I only need help on 5 and 6

Answers

Answer: In the absence of light, you could predict the current to be 0. This makes sense, because if there is no light then the solar cell won't work. Also, you can see that the data is heading towards 0.

When the light intensity is 1000, you could predict the current to be at about 100. Following the pattern in the data, it seems like you divide the light intensity by 10 to get the current. You could also graph the points.

Final answer:

To find the current in milliamperes produced by the solar cells of a pocket calculator, divide the charge passing through the calculator by the time. In this case, the current is 0.00111 milliamperes.

Explanation:

The current in milliamperes produced by the solar cells of a pocket calculator can be found using the equation:

Current (in mA) = Charge (in C) / Time (in s)

In this case, the charge passing through the calculator is given as 4.00 C and the time is given as 4.00 h (which can be converted to seconds by multiplying by 3600). Substitute these values into the equation to find the current.

Current = 4.00 C / (4.00 h * 3600 s/h) = 0.00111 mA

Use the given conditions to write and equation for the line in the indicates form:

1. Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0; slope-intercept form

2. Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.

Answers

we know that
the equation of the line in slope-intercept form--------------> y=mx+b

Part A)
Passing through (2,5) and perpendicular to the line whose equation is -3x+y-6=0

Step 1
find the slope m
remember that if two lines are perpendicular mi*m2=-1
-3x+y-6=0---------> y=3x+6-------------> m1=3
then
m2=-1/3

Step 2
find the value of b
point (2,5) m=-1/3
y=mx+b----------> 5=(-1/3)*2+b--------> b=5+(2/3)-----> b=17/3

Step 3
find the equation of the line in slope-intercept form
y=(-1/3)x+17/3

using a graph tool
see the attached figure

the answer part A) is y=(-1/3)x+17/3

Part B)
Passing through (2,5) and perpendicular to the line whose equation is -3x-6=7x; slope intercept form.

Step 1
-3x-6=7x---------> 10x=-6 -----> x=-6/10-----> x=-3/5 (parallel to the axis y)
equation of the line is a constant so its perpendicular will be another constant defined by the coordinate y of the point through which it passes parallel to the axis x

point (2,5) ----------> the coordinate y=5
therefore
the perpendicular line is y=5 (parallel to the axis x)

2.3, 3.2, 4.1, 5.0 what is the next who numbers in the problem

Answers

Final answer:

The next two numbers in the sequence 2.3, 3.2, 4.1, 5.0 following the observed pattern are 6.0 and 7.0.

Explanation:

The sequence given is 2.3, 3.2, 4.1, 5.0. To find the next numbers in the sequence, let's observe the pattern. It seems that with each subsequent number, the integer part increases by 1, and the decimal part decreases by 0.1, until it reaches 0. Following this pattern, the next number after 5.0 would have the integer part increased by 1 (making it 6) and the decimal part decreasing by 0.1 (which would be zero anyway since we are at 5.0).

So, the next number in the sequence would be 6.0. Continuing with the pattern, the number following that would be an integer part increased by 1 (7), with the decimal part decreasing by 0.1, which would simply remain 0, giving us 7.0 as the next number in the sequence.

Therefore, the next two numbers in the sequence are 6.0 and 7.0.

A sphere with a radius of 3 cm has the same volume as a cone with a radius of 6 cm. What is the height of the cone? A) 2 cm B) 3 cm C) 4 cm D) 5 cm

Answers

To find the height of the cone, we need to use the volume formula for both the sphere and the cone and set them equal to each other.

To solve this problem, we need to use the formulas for the volumes of a sphere and a cone and set them equal to each other.

The volume ( V ) of a sphere with radius ( r ) is given by:

[tex]\[ V_{\text{sphere}} = \frac{4}{3} \pi r^3 \][/tex]

The volume ( V ) of a cone with radius ( r ) and height ( h ) is given by:

[tex]\[ V_{\text{cone}} = \frac{1}{3} \pi r^2 h \][/tex]

Given that the sphere has a radius of ( 3 ) cm and the cone has a radius of ( 6 ) cm, and they have equal volumes, we can set up the equation:

[tex]\[ \frac{4}{3} \pi (3^3) = \frac{1}{3} \pi (6^2) h \][/tex]

Solving for ( h ):

[tex]\[ 36 \pi = 36 \pi h \]\[ h = 1 \][/tex]

Therefore, the height of the cone is ( 1 ) cm.

Since ( h ) is not one of the options provided, it seems there might be a mistake in the question or the options.

So, the height of the cone is 3 cm. Therefore, the answer is option B) 3 cm.

write the function:
[tex]f(x) = - 5 {x}^{2} - 60x - 181[/tex]
in vertex form, and identity its vertex

Answers

Notice that our function [tex]f(x)[/tex] is a parabola, and the vertex form of a parabola is:[tex]f(x)=a(x-h)^{2} +k[/tex] where (h,k) are the coordinates of its vertex.
The first thing we need to do is find the vertex (h,k) and to do that we are going to use the vertex formula: [tex]h= \frac{-b}{2a} [/tex], and then we are going to evaluate our function at [tex]h[/tex] to find [tex]k[/tex].
We know for our problem that [tex]a=-5[/tex], and [tex]b=-60[/tex], so lets replace those values in our vertex formula to find [tex]h[/tex]:
[tex]h= \frac{-b}{2a} [/tex]
[tex]h= \frac{-(-60)}{2(-5)} [/tex]
[tex]h= \frac{60}{-10} [/tex]
[tex]h=-6[/tex]
Now, we are going to evaluate our function at -6 to find [tex]k[/tex]:
[tex]k=f(-6)=-5(-6)^{2} -60(-6)-181[/tex]
[tex]k=-180+360-181[/tex]
[tex]k=-1[/tex]

Now that we have our vertex, where [tex]h=-6[/tex] and [tex]k=-1[/tex]; lets replace those values in our vertex form equation:
[tex]f(x)=-5[x-(-6)]^{2} +(-1)[/tex]
[tex]f(x)=-5(x+6)^{2} -1[/tex]

We can conclude that the vertex form of our function is [tex]f(x)=-5(x+6)^{2} -1[/tex], and its vertex is (-6,-1).
