70% of Ms. Miller's class passed the test on the first try. Those who failed were able to retake and half of those students pass
MrRissso [65]

Answer:

85%

Step-by-step explanation:

  1. Calculate how many students passed on their first try. 20 x 70% is 14, so 14 students passed on their first try.
  2. 6 students retook the test. Half of 6 is 3. Add 3 to the 14 students that passed earlier.
  3. Calculate the percent with the equation 17/20 = 0.85. 0.85 = 85%.

emmainna [20.7K]

Answer:

1 adult cat

<u>Thursday:</u>

The ratio of adult cat to kitten at a pet care center on Thursday was 4:3.

Number of adult cats = 4x

Number of kitten cats = 3x

There were 12 kittens, then

3x=12\\ \\x=\dfrac{12}{3}\\ \\x=4\\ \\4x=4\cdot 4=16

There were 16 adult cats

<u>Tuesday:</u>

17 adult cats were at the pet care center.

<u>Difference:</u>

17-16=1 adult cat

(Picture included)<br> Please solve:
DerKrebs [107]

Answer:

\$16.625\approx \$16.30

Step-by-step explanation:

Original price = $17.50

Discount = 5%

Find the amount of discount (in dollars):

5\%=0.05\\ \\\$17.50\cdot 0.05=\$0.875

Now, the sale price is

\text{Sale Price}=\text{Original Price}-\text{Discount}\\ \\\text{Sale Price}=\$17.50-\$0.875\\ \\\text{Sale Price}=\$16.625\approx \$16.30

If x = t^3 and y = t^2 - 2 , what is y in terms of x?
alekssr [168]

Answer:

E

Step-by-step explanation:

You have to get t^2 in the first equation.

x = t^3                         Take the cube root of both sides

\sqrt[3]{x} = \sqrt[3]{t^3}

\sqrt[3]{x}=t                         Now square both sides

(\sqrt[3]{x})^2 = t^2

x^\frac{2}{3} = t^2

Now you can substitute into the second equation

y = t^2 - 2

y = x^\frac{2}{3} - 2

E
