Area = ( 1/2 × 4 × 3 ) + ( 1/2 × 5 × 6 )

Area = 6 + 15

Area = 21 ft^2

Very important question ☺️

Answer:

130° is the correct answer

∠QPR=80°

∠PQR+∠QPR+∠QRP=180°

∠PQR+∠QRP=100°

2(x+y)=100°

x+y=50°

So, in △QOR

x+y+∠QOR=180°

∴∠QOR=180°−50°

=130°

ASAP PLEASE HELP An ostrich egg has a mass of 1.2 kg to the nearest tenth of a kilogram. Find the minimum and maximum possible m

katen-ka-za [31]

The maximum possible measurement is 1.25 Kg and the minimum possible measurement is 1.15 kg

Solution:

Given mass of an ostrich egg is 1.2 Kg

We have to find the minimum and maximum possible measurements to the nearest tenth of a kilogram

The greatest possible error in measurement nearest tenth of a kilogram, is a half a tenth of a kilogram which is:-

$\frac{1}{2} \times \frac{1}{10}=\frac{1}{20}$

Now, the maximum value will be equal to calculated amount plus the error in measurement of value .i.e.

$\text { Maximum value }=1.2+\frac{1}{20}=1.2+0.05=1.25$

Now, the minimum value will be equal to calculated amount minus the error in measurement of value .i.e.

$\text { Minimum value }=1.2-\frac{1}{20}=1.2-0.05=1.15$

Hence, maximum possible measurement is 1.25 Kg

And the minimum possible measurement is 1.15 kg

(Constructed Response) Determine whether the binomial, 9x² - 49, is a difference of

vovikov84 [41]

Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)

=============================================================

Explanation:

We can write the 9x^2 as (3x)^2 since

(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2

The 49 can be written as 7^2 because 7^2 = 7*7 = 49.

This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.

The difference of squares factoring rule is

a^2 - b^2 = (a-b)(a+b)

which we have a = 3x and b = 7 in this case

So,

a^2 - b^2 = (a-b)(a+b)

(3x)^2 - 7^2 = (3x-7)(3x+7)

9x^2 - 49 = (3x-7)(3x+7)

Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.
