Ms.Lawrence buys 8 ounces of smoked salmon at 17.98 per pound how much money did ms.Lawrence spend on smoked salmon
Answer:
$8.99
Step-by-step explanation:
1 pound = 16 ounces
y pound = 8 ounces
[tex]\frac{1}{16} :\frac{y}{8}[/tex]
y · 16 = 1 · 8
16y = 8
16y ÷ 16 = 8 ÷ 16
y = 0.5
0.5 pound = 8 ounces
----------------------------------
1 pound = $17.98
0.5 pound = y
[tex]\frac{1}{17.98} :\frac{0.5}{y}[/tex]
y · 1 = 17.98 · 0.5
y = $8.99

(a.) y = 6 x^2 + 5x − 4
(b.) y = 4x^2 – 64
Answer:

Phoebe invested $5800 and after one year the investment was worth $6100. How much interest did she receive?
Answer:
Amount of interest received by Phoebe = $300
Step-by-step explanation:
Given:
Amount Phoebe invested = $5,800
Amount Phoebe received after one year = $6,100
Find:
Amount of interest received by Phoebe
Computation:
Amount of interest received by Phoebe = Amount Phoebe received after one year - Amount Phoebe invested
Amount of interest received by Phoebe = 6,100 - 5,800
Amount of interest received by Phoebe = $300

T
✓
Answer:
Easiest to pick (0, 0) and (1, 1) probably, then slope is 1.
Step-by-step explanation:
Rise over run for (0, 0) and (1, 1) is rise up 1 and run over 1, so 1/1.
This means slope is 1
Serena, Alyssa and Katie have just finished lunch at the Rainforest Cafe. Their bill came to $38.96. There is an 8% sales tax. The girls have decided to leave a tip of 15% on the total amount of the bill. How much money did the entire bill come to including the tip?
Answer:
About $48.39
Step-by-step explanation:
Sales tax only applies to the bill, not the tip.
Calculate the sales tax:
38.96 × 8%
38.96 × 0.08
3.1168
Round to the nearest cent:
3.12
Add the sales tax to the bill:
38.96 + 3.12
42.08
Calculate the tip based "on the total amount of the bill:"
42.08 × 15%
42.08 × 0.15
6.312
Round to the nearest cent:
6.31
Add the tip to the rest of the bill:
42.08 + 6.31
48.39

Answer:
[tex]456\ m^2[/tex]
Step-by-step explanation:
In order to find the surface area of a 3-dimensional figure, one must find the 2-dimensional area of all of its faces, then add up the values to find the surface area of the entire figure. The given prism is drawn out in the form of a net, thus, it is rather easy to find the area of each face, and add up the area to find the surface area.
The lateral surface area refers to the surface area of a figure, not including the base of the figure. In this case, the base is the largest rectangle: the one with the dimensions of the following length
[tex](12)*(18)[/tex]
Use the following formulas to find the surface area of each face:
Rectangle: [tex](length)(width)[/tex]
[tex](10)(18)=(180)[/tex]
[tex](10)(18)=(180)[/tex]
Triangle:[tex]\frac{(base)(height)}{2}[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
[tex]\frac{(12)(8)}{2}=48[/tex]
Add up all of these values to find the total surface area:
[tex](180)+(180)+(48)+(48)=456[/tex]

A) −6x−4
B) −4x+2−2x+4
C) −10x
D) −4x-2x−8+4
Answer: A) -6x-4 Hope that helps!

Hi,
I cannot see the options but for vertical compression you need to have values of a that are 0<a<1, then the graph will be compressed.
For example, if we have g(x)= 1/2 x^2 will be compressed by factor of 1/2.

B.
$57
C.
$62
D.
$67

The largest jaw breaker in a store is spherical with a radius of 2 in, and sells for $4.00. A
store wants to make a 6 in. radius jaw breaker. How much should they charge for this
foot long jaw breaker?
Answer:
$36
Step-by-step explanation:
1. Determine the surface area of the largest jaw breaker
Surface area of a sphere = 4πr²
4 x 3.14 x 2² = 50.24in²
2. Determine the surface area of the new jaw breaker
4 x 3.14 x 6² = 452.16 in²
3. Determine the cost per area
4/ 50.24
4. Determine the price for the new jaw breaker
4/ 50.24 x 452.16 = $36
The time spent studying in hours on a daily basis of nine different students was used to create the box plot shown above. Which of the sets of times below matches the given box plot?
Answer:
B.) 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5
Step-by-step explanation:
From the box plot, we can obtain the 5 - Numbe summary and compare with the values in the options given :
Kindly note that each tick mark on the box plot is seperated by a unit of 0.25
Minimum = 0 (starting point of left whisker)
Lower quartile = 0.25 (start point of box)
Median = 0.5 (point in between the box)
Upper quartile = 1.25 (end point of the box)
Maximum = 2.5 (end point of right whisker)
In ascending order we have ;
0, 0.25, 0.5, 1.25, 2.5
The data which best matches the plot is 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5
Brian and his friend Tom had a lemonade stand. They spent $40 on supplies. They sold $160 of lemonade in 5 hours. If the boys split the money left over evenly, how much money did Brian make each hour?
Answer:
40
Step-by-step explanation:
160-40=80/2=40
Answer:
$12/ hour
Step-by-step explanation:
revenue: 160
profit: 160 - 40 = 120
Brian's profit: 120/2 = 60
Hourly profit: 60/5 = 12

an explanation 2 plz thx
Answer:
Solution given:
we have
setup price =$30
as rate for 1 print tickets =$1.05/tickets
so
for t
t=$30+$1.05*t
is a required expression.
the
cost of 300 tickets:
300 tickets =$30+$1.05*300=$345
$345is the cost of 300 tickets.

Step-by-step explanation:
Explain how to calculate the surface area of a composite figure in your own words.
Answer:
tik
Step-by-step explanation:
Answer:
Sample response: First separate the composite into component figures. Then find the surface area of each figure. A two-dimensional net can be used to find the surface area. Add the surface areas of the components. Then, subtract or exclude the areas of the figures that are shared.
When you have two shapes to compare on a coordinate plane, you can determine the scale factor, knowing that the transformation was a dilation. Generate instructions you would give another student to determine the scale factor. If you know the center of dilation is the origin, you can simply divide any non-zero coordinate of the transformed figure by the corresponding coordinate of the original figure to get the scale factor. Sample Response: Locate two corresponding ordered pairs of the two shapes. Calculate how much the pre-image values were multiplied by to obtain the image values. This is your scale factor. You can calculate this by dividing the coordinates of the mage by the corresponding coordinates of the pre-image. Which did you include in your response? Check all that apply. Use corresponding ordered pairs. Divide the coordinates of the image by the pre-image. Determine that the pre-image times the scale factor produces the image.
