There are 700 and 800 marbles. The marbles were purchased in 8 equally- sized bags. The profuct of all the digits is 70.

The price of an item has been reduced by 85%. The original price was $77.

irina1246 [14]

Multiply the original price by the decimal form of the percent and subtract that from the original price.
77*0.85=65.45
77-65.45=11.55
Answer: New price is $11.55

If m1=2x° and m3=3x° what is m1

olga_2 [115]

Answer:

36

Step-by-step explanation:

Using the angle addition postulate

angle 1+angle 2+angle 3=180

Angle 2 is 90 degrees,

Angle 1 is 2x degrees

Angle 3 is 3x degrees

Plug this into equation

$2x + 90 + 3x = 180$

$5x + 90 = 180$

$5x = 90$

$x = 18$

Plug 18 into 2x

$2(18) = 36$

What is the answer I will give brainlyest

Scorpion4ik [409]

Answer:

31.5 squared cm

Step-by-step explanation:

Let's start with the triangle part :)

We have a base half a base of 3, so let's add 3 more to make it complete, which gives us 6.

6cm (base) x 6 cm (height) = 36 cm.

Since it's a triangle, we must divide by 2 which gives us 18 cm.

Now let's move on to the circle.

we have a radius of 3.

in order to find area of a circle, we have to do pi x r squared.

We have a radius of 3 so let's square it, which give us 9. after that we multiply 9 by pi.

In the directions, it says use 3 for pi. So we do

3 x 9 which equals 27.

But WAIT- it's a half circle so we divide 27 by 2 which gives us 13.5 cm.

Let's add the two

18 cm + 13.5 cm = 31.5 cm squared (remember to square it since it's area!!)

I hope this helped!!! <3

One pipe can fill a tank in 8 minutes and second pipe can

Vanyuwa [196]

Answer:

4.8 minutes

Step-by-step explanation:

Pipe 1= 1/8 per min or 3/24

Pipe 2= 1/12 per min or 2/24

(2/24)+(3/24)= 5/24

24÷5= 4.8 min

What is -4/3 on this? Say all that apply (5 stars and brainliest for best answer)

Aleks04 [339]

Answer:

Rational Numbers

Step-by-step explanation:

- An integer in its most simplified form cannot be a decimal nor a fraction, meaning -4/3 nor -0.75 would work.

- A whole number is a number that is either positive or negative but cannot be a decimal in simplified form. -4/3 is -1.333.... which is less than one and negative, meaning it cannot be a whole number due to it obviously being a decimal.

- -4/3 is not a natural number as it is both a decimal and negative.

- -4/3 is not irrational because it repeats when in decimal form.

- -4/3 is rational as in decimal form it repeats and to give more information, rational numbers can be both positive and negative numbers. The 3 that repeats in the decimal form of -4/3 works as a rational number due to this.

Therefore, it would apply to the first square.

Thanks!
