Answer:

c=2.22

Step-by-step explanation:

1/a- 1/b=1/c- 1/d

1/1/2- 1/1/4=1/c- 1/1/5

0.5-0.25=1/c- 0.2

0.25=1/c- 0.2

0.25+0.2=1/c

0.45=1/c

cross multiply

0.45×c=1

0.45c=1

divide both sides by 0.45

0.45c=1/0.45

c=2.22

What is the mass of an object if it takes a net force of 32 N to accelerate

Sonbull [250]

We will find the answer using the second law of motion i.e. Force is equal to the product of mass and acceleration.

$\sf \: F=ma$

Where,

F is force
M is mass
A is acceleration

In our case,

F = 32 N
A = 0.88m/s
M = ?

Let's solve for M ~

$\tt \: 32 = m \times 0.88$

$\tt \: 32 = 0.88m$

$\tt \: 0.88m = 32$

$\tt \: m = 36.36$

Thus, The mass of object is 36.36 grams...~

Graph the solution of this inequality: 4.5x-100 >125

Lubov Fominskaja [6]

$\bf 4.5x-100\ \textgreater \ 125\implies 4.5x\ \textgreater \ 225\implies x\ \textgreater \ \cfrac{225}{4.5}\implies x\ \textgreater \ 50$

Amelie needs 2| 3/8 cups flour for one recipe and 1| 1/3 cups of flour for another recipe.

ryzh [129]

Answer:

3 and 17/24 cups of flour

Step-by-step explanation:

You need to make the denominator the same so find what number the 8 and 3 can both be turned into to make the same number. They can both be made into a 24. 8x3=24 so you multiply the 3 by 3 making 9. Do the same to the 1/3, multiplying both by 8 making 8/24.

2 9/24 and 1 8/24 which can be made into 3 17/24
