Answer:The first one: how many g's are in 38

Step-by-step explanation:

What is g of 48? The term "of" implies multiplication

The total of g and 48? This may not be as obvious, but that's implying addition.

How much more than g is 48? The phrase "how much more than" implies subtraction

Alex Ar [27]

Answer:

210 ways

Step-by-step explanation:

In the question, the combination should be computed.

Number of ways of selection 6 flowers = nCr =10C6

$\frac{n!}{r!(n-r)!}$ = $\frac{10!}{ 6!(10-6)!}$

=3628800/17280

=210

Therefore, there are 210 ways in which 6 flowers can be selected from the available 10 flowers.

. Kite QRST has a short diagonal of QS and a long diagonal of RT. The diagonals intersect at point P. Side QR = 17m, diagonal QS

trapecia [35]

Answer:

495 meter²

Step-by-step explanation:

In the given kite QRST,

PQ = PS = 15 meter

QR = 17 meter

We have to find the area of the kite.

Since kite is in the form of a rhombus.

and rhombus is = $\frac{1}{2}$ (Diagonal QS) × (Diagonal RT)

In Δ QRP,

17² = 15² + RP²

$\sqrt{17^{2}-15^{2}} = RP$

$RP=\sqrt{289-225}$

= √64 = 8 meters.

So RT = RP + PT = 8 + 25 = 33 meter.

Now area of kite = $\frac{1}{2}$ (30) (33) = 495 meter²
