Answer:

$\frac{1}{4}$ cup of cheese

Step-by-step explanation:

The least cheesiest recipe uses $\frac{3}{4}$ cup of cheese while the most cheesiest uses 1 cup of cheese.

$1-\frac{3}{4} =\\\\\frac{1}{4}$

The most cheesiest uses $\frac{1}{4}$ cup more cheese than the least cheesiest.

If Jamie is riding at 14 mph and cori is riding at 0.04km per minute, how far will each of yjem bike in two hours? 1 mile = 1.61

Gelneren [198K]

Answer:

Jamie will have covered a distance of 45.08 km while Cori will be 4.8 km away

Step-by-step explanation:

Here, we want to know how far will each of both riders be in 2 hours time.

Jamie is riding 14 mph

This means the number of miles covered in two hours will be 14 mph * 2 = 28 miles

For comparison purposes, let’s convert this to kilometer.

Since 1 mile = 1.61 km, then 28 miles will be 28 * 1.61 km = 45.08 km

For Cori, he is riding at 0.04 km per minute

1 hour = 60 minutes

so 2 hours = 2 * 60 = 120 minutes

Since the speed is 0.04 km in a minute

Then the distance in 120 minutes will be 0.04 * 120 = 4.8 km

An element with mass 430 grams decays by 27.4% per minute. How much of the element is remaining after 19 minutes, to the nearest

nadya68 [22]

The equation for exponential decay is $y=a*b^x$ , where a is the initial amount, b = 1 + r (the growth rate as a decimal number) and x is the number of time periods (in this case, minutes). Substituting the information we have:
$y=430(1+-0.274)^1^9
\\=430(1-0.274)^1^9
\\=430(0.726)^1^9=0.98$ . To the nearest tenth of a gram, this would be 1.0 grams.

Pls help I don’t get any of them

JulijaS [17]

Answer:

Step-by-step explanation:

28. Area of the circle = π $r^{2}$ where r is the radius of the circle.

Given diameter = 14m, therefore radius = $\frac{14}{2}$ = 7m

Now area of the circle = 49 $\pi ^{2}$ or = 49 * 3.14 * 3.14 = 483.12 $m^{2}$

29. Volume of cylinder = π $r^{2}$ h = π* $1.5^{2}$ * 3 = 6.75π cu. feet or 21.195 cu. feet

30. A ball resembles a sphere. Volume of the sphere = $\frac{4}{3} \pi r^{3}$

Given diameter = 30inches; Therefore, radius = 15 inches

Now, Volume of the ball = $\frac{4}{3} \pi 15^{3}$ = 4500π cu. inches or 14310 cu.inches

Can someone please help me? If g(x) = x2 - 5x + 2, find g(0).

Debora [2.8K]

g(x) = x² - 5x + 2

You are looking for g(0). This means that you must replace all the x values in the equation above with 0

(0)² - 5(0) + 2

Now you need to solve according to the rules of PEMDAS:

(0)² - 5(0) + 2

0 - 5(0) + 2

0 - 0 + 2

0 + 2

g(0) = 2

Hope this helped!

Celine works twice as many hours as she spends in class she studies 4 hours for every hour in class to maintain her health and s

natita [175]

Answer:

she will spend 10 hours in class 40 hours studying and 20 hours working

Step-by-step explanation:

if u simply start at 1 hour of class u get to see the pattern example:

class. study. work

1 4. 2

she works twice as long as she is in class and studies 4 times longer than in class so for every hour she is in class do the math for this condition. for every class hour multiply by 4 to get her study time and then multiply her class hour by 2 to get her work hours. keep going until the total time of all activities adds to 70
