Consider that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. If 1 ounce of cottage cheese is equivalent to 2
VikaD [51]

Answer:

4.42 ounces.

Step-by-step explanation:

We have been given that a 1/2 cup serving of 1% cottage cheese is equivalent to 125 grams. 1 ounce of cottage cheese is equivalent to 28.35 grams.  We are asked to find the ounces in 1/2 cup serving.

We will use proportions to solve our given problem.

\frac{\text{Ounce}}{\text{Grams}}=\frac{1}{28.25}

Upon substituting our given values, we will get:

\frac{\text{Ounce}}{125}=\frac{1}{28.25}

\frac{\text{Ounce}}{125}\times 125=\frac{1}{28.25}\times 125

\text{Ounce}=4.42477876

Upon rounding to nearest hundredth, we will get:

\text{Ounce}\approx 4.42

Therefore, 1/2 cup serving contains 4.42 ounces.

How do you multiply
ikadub [295]
Think of 2 times 2
You would duplicate 2 two times
8 times 8 is 64
6 times 6 is 36
It’s kind of just adding an integer (any number) to the integer that is stated after it

50 BIG POINTS! Help me on math please!  @ Apologiabiology, @ Bookishfairy73

Rate of change is also knkown as slope which is found by
\frac{y2-y1}{x2-x1}=slope if you know 2 points/ordered pairs
aos, if x incheases while y decreases then slope is negative
when x increases while y increases then slpe if positive
also, if you can convert to y=mx+b, m=slope
another thing if you have ax+by=c then slope=-a/b

so first one
2x-5y=15
a=2
b=-5
-2/-5=2/5
slope=2/5
positive

next
y=-4x
-4 =slope=negative


x increases while y decreases
negative

x increases while y decreases
negative


so
Positive
Negative
Negative
Negative





A. 6x-3y=12
sloope=-6/-3=2

B. y=5x+b
slope=5

C. (8-2)/(3-1)=6/2=3
sloope=3

D. goes up 4 units and goes right 1 unit, 4/1=4
sloope=4


5 is greates
B is the answer









A. (6-3)/(4-3)=3/1=3
slope=3

B. y=4+6x
slope=6


C.12x+6y=18
slope=-12/6=-2

D. goes down 5 units as it goest 1 uniit to right aka -5./1
slope=-5


greatest is 6
B is answer











the starting value I would guess si when x=1 what is the greats y value

look at each
first one
A. x=1 and =-3

B.y=3x-8
y=3(1)-8
y=3-8
y=-5

C. 8x+4y=16
8(1)+4y=16
8+4y=16
4y=8
y=2

D. at 1 unit to right it is 1 nit up so y=1


greatest is  2 or C





so just subsitute 1 for x since x represents how many teaspoons
y=16(1)560
y=16+560
y=576 caloris for 1 sugar teaspoon

for honey, just read off the graph
for when x=1
y=504

so calores of sugar=576
calories in honey=504






ANSWERS

Postive
Negative
Negative
Negative

B

B

C

sugar=576
honey=504
