Answer:

6 ways -  ab,ac, ba,bc and ca,cb

Step-by-step explanation:

We are given 3 letters a,b,c.

We can choose the first letter in 1 out of 3 ways.

Once the first letter has been chosen without replacement, we have two letters remaining. Another letter can be chosen from the 2 remaining letters in  2 ways. So the total number of ways of choosing the two letters is 3*2 = 6.

Listing out the possible set of choices:

Options include: ab,ac, ba,bc and ca, cb

Click an item in the list or group of pictures at the bottom of the problem and, holding the button down, drag it into the
BartSMP [9]

Answer:

d = √5 ≈ 2.24

Step-by-step explanation:

B is located at (1, 3) and B' is located at (3, 4)

Distance formula:

[tex] d = \sqrt{(xB' - xB)^2 + (yB' - yB)^2}[\tex]

replacing with the coordinates of the points:

[tex] d = \sqrt{(3 - 1)^2 + (4 - 3)^2}[\tex]

[tex] d = \sqrt{4 + 1}[\tex]

d = √5 ≈ 2.24

The length of a square is 256m and the breadth is 238m what is the perimeter
nikitadnepr [17]

The perimeter is 988 meters

Further explanation:

The given square has different length and breadth which means that the given square is a rectangle.

The formula for perimeter of a rectangle is:

P=2L+2W

Given

Length=L=256m

Breadth=W=238m

Putting the values in the formula:

P=2(256)+2(238)\\=512+476\\=988\ meters

The perimeter is 988 meters.

Dale says the ratios 3:5 and 2:10 are equivalent. Is He correct? Explain
Mnenie [13.5K]

Answer:

No, Dale Isn't correct because 3:5 is greater than 2:10

Step-by-step explanation:

3:5 and 2:10 is the same as in \frac{3}{5}  and \frac{2}{10}

First Find the least common denominator or LCM of the two denominators:

LCM of 5 and 10 is 10

Next, find the equivalent fraction of both fractional numbers with denominator 10

For the 1st fraction, since 5 × 2 = 10,

\frac{3}{5} =\frac{3*2}{5*2} =\frac{6}{10}

Likewise, for the 2nd fraction, since 10 × 1 = 10,

\frac{2}{10} =\frac{2*1}{10*1} =\frac{2}{10}

Since the denominators are now the same, the fraction with the bigger numerator is the greater fraction

\frac{6}{10} >\frac{2}{10} Or\frac{3}{5} >\frac{2}{10}

Hence, \frac{3}{5} is <u>Greater than </u>\frac{2}{10}

Hence, 3:5 is <u>Greater than </u>2:10

Each quadrilateral below is a parallelogram. Find the missing measures
earnstyle [38]

Answer:

ST=3, VT=10, m∠V=48°, m∠T=132°

Step-by-step explanation:

In a parallelogram, opposite sides are congruent and therefore have the same length. Thus, ST=RV=3 and VT=RS=10.

Similarly, opposite angles in a parallelogram are congruent and therefore have the same measure. Thus, m∠V=m∠S=48° and m∠T=m∠R=132°. Hope this helps!
