https://brainly.com/question/11665146

Answer:

We know

y = 3.5x represents the cost of x pounds of raisins.

Also, cranberries costs $18 per 4 pounds

So, to graph these proportions, we have to find the equation for cranberries, if 4 pounds costs $18, that means 1 pound of cranberries is $4.50, this is the ratio of change of cranberries, using this ratio, we can say that the relation is

y = 4.5x

If you compare, cranberries are more expensive than raisins, the image attached shows both proportion graphed.

Therefore, raisins represent the lower unit price, $3.50 per pound, while cranberries represent the higher unit price, $4.50 per pound.

Answer :

well one line takes the slope of y=3.5x

The cranberries take the slope of Y=4.5x

so raisins have the lowest unit price.

Name a possible value for w that is a solution to w > 30, but is not a solution to w < 70.
PLZ HELP RN

Answers

Answer:  w = 100

=============================================================

Explanation:

This value of w is larger than 30, so it makes w > 30 true.

At the same time, this value of w is not smaller than 70, so it makes w < 70 false.

If a value of w makes an inequality true, then we consider it a solution.

Put another way: if w = 100, then w > 30 becomes 100 > 30 which is true while w < 70 becomes 100 < 70 which is false.

You can pick any value you want for the answer as long as it's 70 or larger. We can pick w = 70 because w < 70 becomes 70 < 70 which is false. A number cannot be smaller than itself.

In terms of the graph, you can pick any value that is to the right of 70 or at the location of 70.

Answers

Answer: The Malay world or Malay realm, is a concept or an expression that has been utilised by different authors and groups over time to denote several different notions, derived from varied interpretations of Malayness, either as a racial category, as a linguistic group or as a political-cultural group. The use of the term 'Malay' in much of the conceptualisation is largely based on the prevalent Malay cultural influence, manifested in particular through the spread of the Malay language in Southeast Asia as observed by different colonial powers during the Age of Discovery.

Answers

Answer: z=116 x= 50 1/3

Step-by-step explanation:

64 degrees corresponds to the angle on top of angle z. That means the angle on top of z is also 64 degrees. This same angle and angle z are a linear pair; they sum to 180. 64+z= 180. Subtract 64 from both sides. Z= 116. Angle z and angle (3x-35) are also a linear pair and sum to 180. We know z is 64, so 64+(3x-35) = 180. Combine like terms. 29+3x = 180. Subtract 29 from both sides. 3x = 151. Divide both sides by 3. X= 50 1/3

[tex]\frac{1}{7}[/tex]

Step-by-step explanation:

Given

tanx = [tex]\frac{3}{4}[/tex] = [tex]\frac{opposite}{adjacent}[/tex]

This is a 3- 4- 5 right triangle with hypotenuse = 5, then

cosx = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{4}{5}[/tex]

sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{3}{5}[/tex]

Then

[tex]\frac{cosx-sinx}{cosx+sinx}[/tex]

The Holt family is purchasing 4 cell phones. Store A sells 3 cell phones that cost $165 each, which includes a fourth phone for free. Store B sells the same cell phone for $135 each. Which store has the better deal for purchasing 4 cell phones? Explain.

Answers

Answer:Store A

Step-by-step explanation:

Given

Store A sells 3 cells phones that cost $165 each and offer 4 th one free

i.e. Effective cost of each cell phone is  [tex]\frac{165\times 3}{4}=\$ 123.75[/tex]

Store B sells each cell phone at [tex]\$ 135[/tex] each

clearly, store A provides a better deal than B because the cost of 4 cell phones is less for Store A i.e.

[tex]\Rightarrow 165\times3 <135\times4\\\Rightarrow \$495<\$540[/tex]
