1 answer:

3 0

Answer:

r = 0.85 ft
C = 5.3407075111026 ft
A = 2.2698006922186 ft²

Agenda:

r = radius
C = circumference
A = area
π = pi = 3.1415926535898
√ = square root

Formula:
Circumference of a circle:

C = 2πr = πd

One serving of a certain brand of yogurt contains 12 G of fat the low-fat version contains 38.75% less fat per serving how many

Mkey [24]

Answer:

One serving of law-fat yogurt contains 7.35 g of fat.

Step-by-step explanation:

One serving of

a certain brand of yogurt contains 12 g of fat
the low-fat yogurt contains 38.75% less fat

Let x g be the amount of fat in low-fat yogurt. Then

12 g of fat - 100%

x g of fat - 100% - 38.75% = 61.26%

Write a proportion

$\dfrac{12}{x}=\dfrac{100}{61.25}$

Cross multuply

$100\cdot x=12\cdot 61.25\\ \\100x=735\\ \\x=\dfrac{735}{100}=7.35$

One serving of law-fat yogurt contains 7.35 g of fat.

I really need the answers for these I don't understand this

Yuri [45]

I tryed my best to figure out what all of the numbers were. if i got any wrong then please tell me and i will put the right answer in the comments.

1) 3/5= 5/x (cross multiply)
3x=5(5)
3x=25
x= 25/3 -or- 8.33

2) 2/4=x/12 (cross multiply)
 2(12)=4x
 24=4x
 6=x
3) 10/x=5/9 (cross multiply)
10(9)=5x
90=5x
18=x
4) 5/5=x/18 (cross multiply)
5(18)=18x
90=18x
5=x

Find an equation for the line below

lilavasa [31]

Answer:

$y+1=\frac{-2}{3} (x+4)$

Step-by-step explanation:

you can use the equation point-slope of a line

(y-y1)= m(x-x1)

m is the slope =rise /run

to get from the lower point on the line to the other you rise 4 units and run -6 units so m= -4/6= -2/3

now that you have the slope pick you need one point

pick any poin on the line for example (-4, -1)

now you substitute into the point-slope equation point (-4,-1) and slope -2/3

(y+1)= -2/3(x+4)

in standard form will be

y= $\frac{-2x}{3} -\frac{2*4}{3} -1$

y= $\frac{-2x}{3}- \frac{5}{3}$
