Noah, Luke, Aaron and Nick are playing Pictionary. Noah and Luke scored 135 points while Aaron and Nick scored 160 points. How many points did they have all together and who won?

Answer: x=20/3=6.67

Step-by-step explanation:

To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.

-----------------------------------------------------------------------------

Given

x:10=9:6

Cross Multiply

9·x=6·10

9x=60

Divide 9 on both sides

9x/9=60/9

x=20/3=6.67

Hope this helps!! :)

Answer:

C

Step-by-step explanation:

Method A:

270 decrease 25% =

270 × (1 - 25%) = 270 × (1 - 0.25) = 202.5

202.5 increase 6% =

202.5 × (1 + 6%) = 202.5 × (1 + 0.06) = 214.65

Method B:

270 increase 6% =

270 × (1 + 6%) = 270 × (1 + 0.06) = 286.2

286.2 decrease 25% =

286.2 × (1 - 25%) = 286.2 × (1 - 0.25) = 214.65

Answer:

Step-by-step explanation:

(x+1)(x-3)(x-4) = (x+1)(x²-7x+12) = x³-6x²+5x+12

:::::

(x+3)(x-0)(x-0)(x-5) = (x+3)(x²)(x-5) = (x²-2x-15)x² = x⁴-2x³-15x²

:::::

(x+2)³ = x³ + 3·x²·2 + 3·x·2² + 2³ = x³ + 6x² + 12x + 8

:::::

(x+3)²(x+1) = (x²+6x+9)(x+1) =  x³ + 7x² + 15x + 9

Answer:

RS ≈ 6.4

Step-by-step explanation:

Using the sine ratio in the right triangle

sin39° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{QR}{RS}[/tex] = [tex]\frac{4}{RS}[/tex] ( multiply both sides by RS )

RS × sin39° = 4 ( divide both sides by sin39° )

RS = [tex]\frac{4}{sin39}[/tex] ≈ 6.4 ( to the nearest tenth )

Answer:

30³÷(−5) = -6y²

Step-by-step explanation:

We need to find the value of the given expression :

30³÷(−5)

It can be written as :

[tex]\dfrac{30xy^3}{(-5xy)}=\dfrac{30}{-5}\times \dfrac{xy^3}{xy}\\\\=-6\times y^2\\\\=-6y^2[/tex]

So, the value of the given expression is [tex]-6y^2[/tex].

Step-by-step explanation:

total ratio is 5

first find the total amount

bob's ratio is 2/5

so 2/5 ×total amount=8 pounds

0.4 ×total amount=8 pounds

total amount=8/0.4=20 pounds

so chris receives: 20-8=12 pounds

Answer:

The correct answer is option B.  17

Step-by-step explanation:

It is given that, ZX bisects ∠WZY. If the measure of ∠YXZ is (6m – 12)°

To find the value of m

From the figure we can see that, triangle WYZ is an isosceles  triangle.

ZW = ZY

Then <YXZ = <WXZ = 90°

It is given ∠YXZ  = (6m – 12)°

(6m – 12)° =  90°

6m = 90 + 12  = 102

m = 102/6 = 17

Therefore the value of m = 17

The correct answer is option B.  17

Answer:

its 17. so B

Answer:

Volume = 2,258.67 cm³

Step-by-step explanation:

Volume of the object = volume of hemisphere + volume of cylinder

= ⅔πr³ +πr²h

Where,

π = 22/7

r = 7 cm

h = 10 cm

Volume = (⅔*22/7*7³) + (22/7*7²*10)

Volume = 2,258.67 cm³

Answer:

D) 126 in²

Step-by-step explanation:

A rectangular prism is 3 inches long, 5 inches wide, and has a height of 6 inches. What is its surface area?

The formula for the surface area of a rectangular prism =

A=2(wl+hl+hw)

Where

W= Width = 5in

H = Height = 6 in

l = Length = 3 in

Surface area =

2(5 × 3 + 6 × 3 + 5 × 6) square inches

2(15 + 18 + 30) square inches

2(63) square inches

= 126 square inches (in²)

Option D is correct

Answer:

18(x + 2)

Step-by-step explanation:

-4/5 ( 30x -  40) + (42x + 4) = -24x + 32 + 42x + 4 = 18x + 36 = 18(x + 2)

Answer:

18x+36

Step-by-step explanation:

1. Simplify  \frac{4}{5}(30x-40)54(30x−40)  to  \frac{4(30x-40)}{5}54(30x−40).

-\frac{4(30x-40)}{5}+42x+4−54(30x−40)+42x+4

2. Factor out the common term 1010.

-\frac{4\times 10(3x-4)}{5}+42x+4−54×10(3x−4)+42x+4

3. Simplify  4\times 10(3x-4)4×10(3x−4)  to  40(3x-4)40(3x−4).

-\frac{40(3x-4)}{5}+42x+4−540(3x−4)+42x+4

4. Simplify  \frac{40(3x-4)}{5}540(3x−4)  to  8(3x-4)8(3x−4).

-8(3x-4)+42x+4−8(3x−4)+42x+4

5. Expand by distributing terms.

-(24x-32)+42x+4−(24x−32)+42x+4

6. Remove parentheses.

-24x+32+42x+4−24x+32+42x+4

7. Collect like terms.

(-24x+42x)+(32+4)(−24x+42x)+(32+4)

8. Simplify.

Step-by-step explanation:

Answer:

y = 4/3x-7/3

Step-by-step explanation:

Slope intercept form is y=Mx+b; m=slope & b= y intercept

y=-4/3x+b

Now substitute x & y with the point given

(-9)=-4/3(5)+b

-9= -20/3+b

+20/3 +20/3

-7/3=b

Now substitute this into the original equation

y = 4/3x-7/3

Answer:

he can buy 10 peaches.

Step-by-step explanation:

7 mangoes will be 12.25. so you subtract his original money(20) from 12.25 which gives you 7.75. then divide 7.75 by 0.75(cost of a peach) and your answer will be 10(rounded off).

Answer:

(x,y): (6 , -3) or (-30/7 , 33/7)

Step-by-step explanation:

6x + 8y = 12

x = y + 9 or   y = x+ 9

if x = y+9

6*(y+9) + 8y = 12

14y = -42

y = -3 and x = 6

if y = x+9

6x + 8*(x+9) = 12

14x = -60

x = -30/7   and y = 33/7

Answer:

Radius is 3.5 cm

Diameter is 7 cm

Step-by-step explanation:

Radius is half the diameter

They give you the diameter at 7 cm

Then you have to half that to get 3.5 cm as the radius

Answer:

The answers are the diameter is 7 because whatever the line across is it's the diameter and the radios is half of what the diameter is so whatever is half of 7 is your radios.

Step-by-step explanation:

Diameter: 7

Radios: 3.5 or 3 1/2

Answer:

answer would be (1,-1)

Step-by-step explanation:

Dialation means to multiply, so u would multiply the point where D is so in the graph it shows D is on 2, -2 so you would multiply 2 by 1/2 and -2 by 1/2 which would give you (1, -1)

[tex]y=3x[/tex]

Step-by-step explanation:

[tex]Ax+By+C[/tex] ⇒ [tex]y=mx+b[/tex]

[tex]3x+y=0[/tex]

Since there are no coefficients on the [tex]y[/tex], you can convert the equation in one step.

Subtract [tex]3x[/tex] from both sides

[tex]y=3x+0[/tex] [tex]or[/tex] [tex]y=3x[/tex]
