If I use 1 pound of sausage for 3/4 pound of cheese how much sausage do I need if I use 1 pound of cheese
Answer:
1.33Step-by-step explanation:
3/4 = 0.75 pound
1 : 0.75 = x : 1
x = 1 * 1 : 0.75
x = 1.33
--------------check
1 : 0.75 = 1.33 : 1
1.33 = 1.33
the answer is good
Answer:
[tex]1 \frac{1}{3}lb \: sausage[/tex]
Step-by-step explanation:
What Iike to do is make it like a ratio.
So you have one pound of sausage per 3/4lb of cheese
[tex] \frac{1lb \: sausage}{( \frac{3}{4} )lb \: cheese} = \frac{sausage}{1lb \: cheese} [/tex]
Then you just make that sausage the subject of the equation by multiplying 1lb cheese to both sides of the equation, and you have your answer.
[tex]1lb \: cheese \times \frac{1lb \: sausage}{0.75 \: lb \: cheese} = sausage[/tex]

5. Rewrite the quadratic funtion from standard form to vertex form.
Ax) = 2x2 + 8x + 70
Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

A shipping container will be used to transport several 150-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 6400 kilograms have already been loaded into the container.
Answer:
[tex]x<=118[/tex]
Step-by-step explanation:
We already have [tex]10300[/tex] kilograms, we will add [tex]x*150[/tex] kilograms, and we need it to be less than or equal to [tex]28000[/tex].
So, the inequality is [tex]150x+10300<=28000[/tex].
We can subtract [tex]10300[/tex] from both sides to get [tex]150x<=17700[/tex].
We then lastly divide by [tex]150[/tex] on both sides to get [tex]x<=118[/tex].
So, the answer is [tex]\boxed{x<=118}[/tex] and we're done!

Sam walked x miles at 4mph.
Then he walked 2x miles at 3mph.
A) find average speed for the whole journey.
The second part of journey took 25mins longer than the first part.
B) Find the value of x.
Answer:
Sam average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Step-by-step explanation:
Formula: Speed = [tex]\frac{Distance}{Time}[/tex]
i.e. Time = [tex]\frac{Distance}{Speed}[/tex]
If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours
If he then walked 2x miles at 3 mph, then time for this period = [tex]\frac{2x}{3}[/tex]hours
Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]
=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]
=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]
=[tex]\frac{3}{\frac{3+8}{12} }[/tex]
=[tex]\frac{3 x 12}{11}[/tex]
=[tex]\frac{36}{11}[/tex]
=[tex]3\frac{3}{11} mph[/tex]
Hence, Same's average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]

On a shopping trip, Gina buys two books priced $4.99 and $12.99. She also buys 2 notebooks, 2 packs of pencils, and 3 composition books. The books are on sale for 10% off the list price and school supplies are 15% off. The store charges 6.5% sales tax.
Item Cost ($)
Notebooks 2.88
Composition Books 0.79
Pencil Packs 1.89
How much total will Gina spend on her shopping trip? Round to the nearest cent.
Answer:
$28.00
Step-by-step explanation:
$4.99 + $12.99 = $17.98 with 10% of discount =$16.18
$2.88 (2) + $0.79 (3) + 1.89 (2) = $11.91 with 15% of discount = $10.12
$16.18 + $10.12 = $26.30 with 6.5% sales tax = $28.00

Aiden buys ice cream and apples at the store.
He pays a total of $15.05.
• He pays a total of $3.80 for the ice cream.
• He buys 3 bags of apples that each cost the same amount.
Write and solve an equation which can be used to determine x, how much each bag
of apples costs.
Answer:
Equation: y = 3x + 3.80
Cost of each bag: $3.75
Step-by-step explanation:
y = 3x + b
y = $15.05
x = cost of each bag
b = $3.80
3 = # of bags
15.05 = 3x + 3.80
11.25 = 3x
3.75 = x
The equation to determine x is y = 3x + 3.8
and cost of each apple bag is $3.75.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
Total amount paid by Aiden = $15.05
Total amount paid for ice cream = $3.80
Number of bags of apple = 3
So if x is the amount of each apple bag and y is the total amount paid by Aiden,
So,Cost of apple bags = 3x
And total amount = 3x + 3.8
or y = 3x + 3.8
this is the equation to determine x.
Now since, total amount paid is $15.05
⇒ 15.05 = 3x + 3.8
or,3x = 15.05 - 3.8
or 3x = 11.25
⇒ x = 11.25/3
⇒ x = $3.75
Thus,the equation to determine x is y = 3x + 3.8
and cost of each apple bag is $3.75.
