Rosa’s market sells deli meats by the pound. The prices for several different meats are shown in the table, Chicken=2.00$ Beef=7.00$ Turkey=3.00$ pork=5.00$ how much more does 1 and 1 half pounds of beef cost than 1 and 1 half pounds of turkey

Answers

Answer: 1.75 more pounds!

Explanation: Beef: 1 pound is $4.25. now divide $4.25 by 4 to get 1/4 of the price for a pound. then add 1 pound of beef ($4.25) and 1/4 pound of beef ($1.06) which gives you $5.31

Beef:  1 pound is $2.85. now divide $2.85 by 4 to get 1/4 of the price of a pound. then add 1 pound of turkey ($2.85) and 1/4 pound of turkey ($0.71) which gives you $3.56

Now, 1 1/4 pounds of beef and 1 1/4 pounds of turkey subtract them and that gives you $1.75.

What is the length of the missing side?

Answers

Answer:

  10

Step-by-step explanation:

The Pythagorean theorem tells you the relationships of sides in a right triangle is ...

  a² + b² = c² . . . . . . where 'a' and 'b' are the legs, and 'c' is the hypotenuse

  6² +8² = c²

  36 +64 = c² = 100

  c = √100 = 10

The length of the hypotenuse is 10.

_____

Additional comment

The ratio of the leg lengths is 8/6 = 4/3. The only right triangle with legs in the ratio 4/3 has the relationship ...

  hypotenuse : long leg : short leg = 5 : 4 : 3

If you multiply these numbers by 2, you see they correspond to the side lengths in this triangle. Your familiarity with a 3-4-5 right triangle can let you write down the answer immediately.

Write the equation of the line in fully simplified slope intercept form

Answers

Answer:

y = x + 8

Step-by-step explanation:

It is y = 1/1x + 8, but we don't put the one if it's at the botton. So, y = 1x + 8, but, when a one is in front of the x, we don't put it either. The answer is

y = x + 8

The y-intercept is where the line "touches" the y-intercept, in this case, 8.

The slope is how many times you go up-down, and to side from point to pint, in this case 1/1.

Makes sense? If so, hope this helps!

Answer:

y = -1x + 8 or y = -x + 8 (both are same)

Step-by-step explanation:

m = slope

slope = y2 - y1 / x2 - x1

4 - 6 / 4 - 2 = -2/2 = -1

m = -1  

b = y-intercept

b = 8

y = mx + b

y = -1x + 8

y = -x + 8

Answers

Answer:

It's c

Step-by-step explanation:

The sales after 12 weeks is about $93. Therefore, option B is the correct answer.

What is an equation?

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The given equation is s=12√4t+10, where s represents the total sales in thousands) and t represents the time in weeks after release.

The sales 12 weeks after release is

s=12√4×12+10

s=12√48+10

s=93.13

s=93

Therefore, option B is the correct answer.

I'm pretty sure that I'm making a mistake but I cant find it (probably because I'm sleep deprived).

Answers

Answer:

I'm not entirely sure, but I think since you're dealing with area, that changes the way you'd do the math.

Step-by-step explanation:

Since centimeters will have a larger number than meters, that being a number 100x larger, the area is gonna appear a lot bigger. Let's say you have a tile that's 2cm x 4cm with an area of 8cm^2. If you double the sides to 4cm x 8cm, your area will quadruple to 32cm^2.

I think that's what is happening in terms of your problem.

find the value of a and b when x=12
a = 5x (squared) / 2 = 360
b = 2x (squared) * (x-5) / 10x = ?

Answers

Step-by-step explanation:

[tex]a = \frac{ 5{x}^{2} }{2} = 360 \\ b = \frac{2 {x}^{2}( x - 5) }{10x} [/tex]

a =

[tex] \frac{5( {12}^{2} )}{2} = 360 = a \\ \frac{5(144)}{2} = 360 = a \\ 5(72) = 360 = a \\ a = 360[/tex]

b =

[tex]b = \frac{2 {x}^{2} (x - 5)}{10x} \\ b = \frac{x(x - 5)}{5 } \\ b = \frac{ {x}^{2} - 5x}{5} \\ b = \frac{ {12}^{2} - 5(12) }{5} \\ b = \frac{144 - 60}{5} \\ b = \frac{84}{5} \\ b = 16.8[/tex]

The required values are a = 360 and b = 16.8 when x = 12.

What is a numerical expression?

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

The numerical expressions are given as:

a = 5x²/ 2 = 360

b = 2x² × (x-5) / 10x

To find the value of a when x = 12, we can substitute 12 for x in the expression for a:

a = 5(12)² / 2 = 360

To find the value of b when x = 12, we can substitute 12 for x in the expression for b:

b = 2(12)² × (12-5) / 10(12)

= 2(144) × 7 / 120

= 288 × 7 / 120

= 2016 / 120

= 16.8

Therefore, when x = 12, a = 360 and b = 16.8.

Which equation represents the line through (0,0) and (2,5)?

What is an equation of the line?

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line is:-

y = mx + c

Given that the line passes through (0,0) and (2,5). to calculate the equation we need to calculate the slope of the line.

m = ( y₂ - y₁) / ( x₂ - x₁ )

m = ( 5 - 0 ) / ( 2 - 0 )

m = ( 5 / 2 )

y = ( 5 / 2)x + c

0 = 0 + c

c = 0

Y = ( 5 / 2)x

Therefore, the equation of the line passing through (0,0) and (2,5) will be y = ( 5 / 2 )x. The correct option is C.
