Answer:
Yes.
Step-by-step explanation:
Though x and y can be achieved in a system of equations. The equation
x (t)=0.0411905(t^2)+(-0.164619)t+28.0114
And
y (t)=-0.024127(t^2)+(-0.591143)t+(-87.4403)
Are not system of equations but rather two different models of equations. Nevertheless
To find t in the first equation, x(t) has to be equal to zero.
When the t is substituted in the second equation, t will completely disappear. Given the value of y(t) and vice versa.
Answer:
216cm³
Step-by-step explanation:
Correct question is 'A prism has a length of 12 centimeters, height of 9 centimeters, and width of 2 centimeters. The volume of the prism is ___cm3.'
Volume'V' of a Rectangular Prism is given by
V = lwh
where,
Length 'l'= 12 cm
Height 'h'= 9 cm
Width 'w'= 2 cm
V = 12 x 9 x 2
V = 108 x 2
V = 216
V = 216cm³
1, 000 grams = 1 kg
(divide both sides by 1, 000)
1 gram = 1/1, 000 kg
750 grams = 750 x (1/1000) kg = 0.75 kg
Therefore, Steven needs to buy 0.75 kg of sugar!

Answer:
2.625 cups or 21 ounces
Step-by-step explanation:
Ava needs 3/4 cup of blue paint for every 1 cup of white paint. So, the ratio is 0.75 : 1.
She has 28 ounces of white paint. But, you have to convert ounces to cups.
1 cup = 8 ounces
28 ounces ÷ 8 ounces/cup = 3.5 cups
Now set up a ratio.

X (how much blue paint is needed) is over 3.5 cups (the amount of white paint she has)
Cross multiply and divide.

x = 0.75 × 3.5
x = 2.625 cups
To convert to ounces, multiply by 8.
2.625 cups × 8 ounces = 21 ounces
Therefore, Ava needs 2.625 cups or 21 ounces of blue paint.
Hope that helps.
Johns total at the deli is $ 7.58
<u>Solution:</u>
Given, John went to the deli on his lunch hour he bought 1.3 lbs of roast beef and 0.6 lbs of cheese both were on sale for $3.99 per pound.
We have to find the nearest cent how much was Johns total at the deli
Now, we know that, total cost = cost of beef + cost of cheese
Total cost = amount of beef bought
cost of beef per pound + amount of cheese bought
cost of cheese per pound
Total amount = 1.3
3.99 + 0.6
3.99
Total amount = 3.99(1.3 + 0.6) = 3.99 x 1.9
Total amount = 7.581
Hence, the total amount was $7.58
