6. In a jar of 650 marbles, 20% of the marbles are red.
How many marbles are not red

Answers

Answer 1

Answer:

Step-by-step explanation:

20% of 650

1/5 of 650

130=red

520= not red

Answer 2

Answer:

520

Step-by-step explanation:

20% are red which means 130 are red

650-130= 520

or you could look at it this way

if 20% is red that means 80% is not red

80% of 650 is 520

Answers

Answer:

  B)  x = 4

Step-by-step explanation:

Perhaps angles A and D are adjacent, so have a sum of 180°.

  133° + (3x +35)° = 180°

  3x +168 = 180 . . . . . . . . simplify

  x + 56 = 60 . . . . . . . . . . divide by 3

  x = 4 . . . . . . . . . . . . . . . . subtract 56

Enter the unknown value that makes this statement true:
50% of is 19.

Answers

Answer:

38

Step-by-step explanation:

Mel Ting sells half-gallons of frozen yogurt for $5 each and gallons for $9 each. One day Mel sells a total of 40 containers of yogurt, for a total of $248. How many of each kind of container did Mel sell?

Answers

Answer:

Number of half-gallons containers of frozen yogurt = 28

Number of containers containing 1 gallon of frozen yogurt = 12

Step-by-step explanation:

Let [tex]x[/tex] denotes number of half-gallons containers of frozen yogurt and [tex]y[/tex] denotes number of containers containing 1 gallon of frozen yogurt.

[tex]x+y=40\,\,\,...(i)\\5x+9y=248\,\,\,...(ii)[/tex]

Multiply (i) by 5

[tex]5x+5y=200\,\,\,...(iii)[/tex]

Subtract (iii) from (ii)

[tex](5x+9y)-(5x+5y)=248-200\\5x+9y-5x-5y=48\\4y=48[/tex]

[tex]y=\frac{48}{4}=12[/tex]

Put [tex]y=12[/tex] in (i)

[tex]x+12=40\\x=40-12\\x=28[/tex]

Alrighty! D represents the miles. It is constant, or exact, the whole time (t).

Knowing that, we can write the equation, almost like a story.

Answers

the answer i believe is c
B. x=5*sqrt3
you can solve this by using :
a^2+b^2=c^2
Remember that you can only use this equation for right triangles & the longest side will always be c !!

so plug in what is given to you.
a^2+11^2=14^2

simplify.
a^2+121=196

our goal now is to get a(x) by itself.
subtract 121 on both sides.
a^2=75

again, we want a(x) by itself.
square root both sides.
a=8.6602

5*sqrt3 = 8.6602

Hope this helps!! :)

Calculate the value of w.
Show your working.
+

Answers

Answer:

w = 2.5

Step-by-step explanation:

6cm * wcm = 5cm * 6cm / 2;  divide both sides by 6cm

wcm = 5cm / 2; calculate

wcm = 2.5cm; divide both sides by 1cm ;)

w = 2.5

The value of w is 2.5 cm.

What is the area of the rectangle?

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

We are given that the triangle and the rectangle have the same area.

Therefore,

Area of triangle = Area of rectangle

6cm x w cm = 5cm x 6cm / 2;  

Now divide both sides by 6cm;

w cm = 5cm / 2

Then calculate;

w cm = 2.5cm

Now divide both sides by 1 cm;

w = 2.5

Therefore, the value of w is 2.5 cm.
