Answer:

<1 = 50

<2 = 40

<3 = 90

<4 = 90

<5 = 40

<6 = 50

<7 = 130

Step-by-step explanation:

<5 + <6 = 90

40 + <6 = 90

<6 = 50

<5 = <2 because of vertical angles

<2 = 40

<6 = <1 because of vertical angles

<1 = 50

<7 = <4 + <5

<7 = 90 + 40

<7 = 130

Answer:

Solution given:

<4=90°[vertically opposite angle]

<2=<5=40°[vertically opposite angle]

<3=90°[right angle]

again

<1+<2=90°[right angle]

<1=90°-40°=50°

<1=50°

again

<5=40°[given]

<6=<1=50°[vertically opposite angle]

<6=50°

again

<7=<4+<5=90°+40°=130°

How to do this question by proving the identity?

jeyben [28]

$\sin^3 \theta-\cos^3 \theta=(\sin \theta-\cos \theta)(\sin \theta\cos \theta+1)\\\\
(\sin \theta-\cos \theta)(\sin^2 \theta+\sin \theta\cos \theta +\cos^2 \theta)=(\sin \theta-\cos \theta)(\sin \theta\cos \theta+1)\\\\
(\sin \theta-\cos \theta)(\sin \theta\cos \theta+1)=(\sin \theta-\cos \theta)(\sin \theta\cos \theta+1)\\\\$

Mr. Lincoln buys juice and water for the school picnic. A pack of 8 juice boxes ca

alexgriva [62]

Answer:

5x + 3y = 95

8x + 6y = 170

x = 10 ; y = 15

Step-by-step explanation:

Let :

x = pack of juice boxes

y = pack of water bottles

Pack of juice box = $5

Pack of water bottles = $3

Amount of money spent :

5x + 3y = $95

Number of drinks purchased :

8x + 6y = 170

Using both equations ;

5x + 3y = 95 - - - (1)

8x + 6y = 170 - - - (2)

Multiply (1) by 6 and (2) by 3

30x + 18y = 570

24x + 18y = 510

Subtract :

6x = 60

x = 60 / 6

x = 10

Put x = 10 in (1)

5(10) + 3y = 95

50 + 3y = 95

3y = 95 - 50

3y = 45

y = 45 / 3

y = 15

x = 10 ; y = 15

What is the growth rate for 3x-y=8x-7

nydimaria [60]

Answer:

you mean like this :))

-5x +7 = Y

Step-by-step explanation:

3x - y = 8x - 7

<=>3x - 8x = y - 7

<=>-5x = y - 7

<=>-5x + 7 = Y

A machine paints 34o toy boats im 3/4 of an hour how many boats can he make per hour

leonid [27]

Here, we can set up a proportion:

34 ÷ 3/4 = ? ÷ 1
34*1 = 34
34÷3/4 = the time needed to build one toyboat

34/3/4 = 45.3333333333

45.3 repeating is not a whole number, so we need to approximate.

45 is the closest whole number,

So.. a machine can paint 45 toy boats per hour.

I really hope that helped! :)
