Answer:

The value of x is 62°.

Step-by-step explanation:

It's 62° because it's a right angle (from the small box) . So you would do the given measurement (28°) and subtract that from 90°.

The product of two mixed numbers x and y is 10. If x= _ 2/3 and y=_ 3/4 , find x and y?

Akimi4 [234]

Answer:

x = 2 2/3
y = 3 3/4

Step-by-step explanation:

There may be other ways to do this. Here's the approach I took. Let the integer part of x be represented by "a", and the integer part of y be represented by "b". Now, we have ...

(a +2/3)(b +3/4) = 10

Multiplying by 12, this becomes ...

(3a +2)(4b +3) = 120

There are only 16 divisors of 120, so they can be easily enough checked one at a time.

120 = 1·120 = 2·60 = 3·40 = 4·30 = 5·24 = 6·20 = 8·15 = 10·12

Of these divisors, the ones that are of the form 3a+2 are ...

2, 5, 8, 20 . . . . a=0, 1, 2, 6

The ones that are of the form 4b+3 are ...

3, 15 . . . . b = 0, 3

The factor pair that consists of a number on the first list and a number on the second list is ...

120 = 8·15

corresponding to a=2 and b=3. So, the mixed numbers you want are ...

x = 2 2/3

y = 3 3/4

_____

Check

(2 2/3)·(3 3/4) =2·3 +2·3/4 +2/3·3 +2/3·3/4 = 6 +6/4 +2 +2/4 = 8+8/4 = 10

Find the area of the irregularly-shaped hexagon below

Ber [7]

let each box length be 1

for white triangle

area = ½bh

=½(4)(2)

for orange triangle

area=½(2)(3)

for blue marked boxes

each of the box

area=l²

=(1)²

there are 16 boxes

so the total area will be 16

total area of the hexagon = 4+3+16

=23 square units

What is the line of symmetry for the parabola whose equation is y = 3x2 + 24x - 1?

meriva

Hello :
y = 3x2 + 24x - 1
= 3(x²+8x) -1
= 3 (x² +2(4)(x) +4²- 4² ) -1
= 3((x+4)² -16)-1
y = 3(x+4)² - 49
the line of symmetry is : x= - 4
