Answer:

74.36 m^2 is the total flooring area in m^2.

Step-by-step explanation:

10 - 8 by 10 ft kitches comes to 800 ft^2.  We need to convert this to m^2.  Recall that 1 m = 3.28 ft.  From this we know that (1 m)^2 = (3.28 ft)^2 = 10.76 ft^2.

Multiply 800 ft^2 by the conversion factor  (1 m)^2 / 10.76 ft^2.  We get:

74.36 m^2.

Let a⃗ =4ı^−2ȷ^, b⃗ =−3ı^+5ȷ^, and e⃗ =2a⃗ +3b⃗ . part a write vector e⃗ in component form.
ch4aika [34]

We have been given that:

Vector \vec{a}=4\hat i-2\hat j and \vec{b}=-3\hat i+5\hat j.

Component form of a vector implies to write the vector with each individual components.

Now, our vector \vec e is given by

\vec e =2\vec a+3\vec b

Now, 2 \vec a=2(4\hat i- 2 \hat j)=8 \hat i -4 \hat j

and 3 \vec b= 3(-3 \hat i +5\hat j)=-9 \hat i + 15\hat j

Plugging the values  of 2 \vec a and 3\vec b, we get:

\vec e = 8 \hat i-4 \hat j-9 \hat i + 15 \hat j=- \hat i+11 \hat j

So, the vector 'e' in its component form is given as:

\vec e= -\hat i+11\hat j

What is the least common denominator of 4/7, 5/14, and 4/15.
lukranit [14]

Answer:

210

Step-by-step explanation:

Rewriting input as fractions if necessary:

4/7, 5/14, 4/15

For the denominators (7, 14, 15) the least common multiple (LCM) is 210.

LCM(7, 14, 15)

Therefore, the least common denominator (LCD) is 210.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

4/7 = 4/7 × 30/30 = 120/210

5/14 = 5/14 × 15/15 = 75/210

4/15 = 4/15 × 14/14 = 56/210

Expand 0.075(22+1.25s) and round to the nearest hundredth
weeeeeb [17]

0.075(22 + 1.25s) = 1.65 +0.09375s

= 1.65 + 0.09s (round to the nearest hundredth)
