The square root can be rewritten as the exponent of 1/2 or 0.5, and because x-3 is all under the square root, it can be written in parentheses as = (x-3)^1/2

(X-3)^1/2

when your trying to convert from square root to exponent imagine the 2 outside of the square root and an exponent of 1 already attached to the value inside

same goes for when the square root is asking for 3 instead of 2 you would just have to convert te exponent to (random value)^1/3

What is 2/7 ÷ 4/21 fully reduced
NikAS [45]
When dividing fractions, you flip the second fraction and multiply

\dfrac{2}{7} \div \dfrac{4}{21}~becomes~\dfrac{2}{7}*\dfrac{21}{4}

Next, we multiply:

\dfrac{2}{7}*\dfrac{21}{4}=\dfrac{42}{28} = \dfrac{21}{14}= 1 \dfrac{1}{2}

How much cardboard will be needed to make the box? 4 feet by 3 feet with a height of 2 feet
sergiy2304 [10]

Answer:

52 ft²

Step-by-step explanation:

When you are calculating the amount of cardboard needed to make a box, you are trying to the the <u>surface area</u>.

The formula for surface area of a rectangular prism is:

SA = 2(lw + hl + wh)

The dimensions for the box are written l X w X h (length times width times height).

We know:

l = 4

w = 3

h = 2

The units for surface area is the unit squared. Feet squared is ft². Be sure the include the units.

Substitute these numbers into the formula. When solving, solve in the BEDMAS order (brackets, exponents, division and multiplication, addition and subtraction).

SA = 2(lw + hl + wh) u²

SA = 2((4*3) + (2*4) + (3*2)) ft²      Multiply within each smaller bracket

SA = 2(12 + 8 + 6) ft²          Add inside the brackets

SA = 2(26) ft²        Multiply

SA = 52 ft²         Final answer

Therefore 52 square feet of cardboard will be needed to make the box.

Two cards are drawn, without replacement, from a standard 52-card deck. Find the probability of each of the following events: a)
aleksandrvk [35]

Answer:

Step-by-step explanation:

given that two cards are  drawn, without replacement, from a standard 52-card deck.

a) Both cards are red

Here there are 26 red cards and 52 total cards.  

Probability = \frac{26C2}{52C2} \\=\frac{26*25}{52*51} \\=\frac{25}{102}

b) Both cards are the same color

i.e. either both are red or both are black

Hence probability = twice of part a

= \frac{2*25}{102} \\=\frac{25}{51}

c) The second card is a queen, given that the first card is an ace.

If first card is an ace remaining are 51 cards with 4 queens\

So prob = 4/51
