Daniela painted a photo that was 4/5 afoot by 1 7/8 of afoot. What was the area?

Ahat [919]

Answer:

$\frac{3}{2}$ square feet

Step-by-step explanation:

The dimensions of the photo is 4/5 by 1 7/8 of a foot.

But,

1 7/8 = $\frac{15}{8}$ feet

So that,

length of the photo = $\frac{15}{8}$ feet

width of the photo = $\frac{4}{5}$ feet

The area of the photo = length x width

= $\frac{15}{8}$ x $\frac{4}{5}$

= $\frac{60}{40}$

= $\frac{3}{2}$

Area of the painted photo is $\frac{3}{2}$ square feet.

2.1x10^6 ______ 7x10^3 answer in standard form ...................10^......

VMariaS [17]

Given:

The expression is:

$\dfrac{2.1\times 10^6}{7\times 10^3}$

To find:

The simplified form of the given expression in standard form.

Solution:

We have,

$\dfrac{2.1\times 10^6}{7\times 10^3}$

It can be written as:

$\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21\times 10^5}{7\times 10^3}$

$\dfrac{2.1\times 10^6}{7\times 10^3}=\dfrac{21}{7}\times \dfrac{10^5}{10^3}$

$\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^{5-3}$ $[\because \dfrac{a^m}{a^n}=a^{m-n}]$

$\dfrac{2.1\times 10^6}{7\times 10^3}=3\times 10^2$

Therefore, the required value is $3\times 10^2$ .

Consider again the two points F(−9, 0) and ????(9, 0) in the coordinate plane. The equation of the

uysha [10]

Answer:

k = 2a = 10

Step-by-step explanation:

x² / 25 − y² / 56 = 1

we know that

a² = 25 ⇒ a = 5

b² = 256 ⇒ b = √256

The equation of the hyperbola defined by |FP − PG| = k can be written as follows:

|FP − PG| = 2*a

then

2*a = 2*5 = 10
