Ey can someone answer my question please cause i've posted it a few times and nothing happen

Answer:

3 [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

Maria only combined two different types of flour to the cake. Therefore, in order to find the total amount of flour she added we need to add these measurements together. First, we need to find a common denominator. We do this by multiplying the numerator and denominator of the amount of whole wheat flour by 2. This would be the easiest way of giving us the same denominator as the measurement for the all-purpose flour.

[tex]\frac{1 * 2}{4 * 2}[/tex] = [tex]\frac{2}{8}[/tex]

Now that we have the same denominators we can simply add both measurements together

3 [tex]\frac{1}{8}[/tex] + [tex]\frac{2}{8}[/tex] = 3 [tex]\frac{3}{8}[/tex]

Answer:

v= -5.8

Step-by-step explanation:

-12v+1+2v=57

-10v+1=57

-10v=58

v= -5.8

I dont understand 2/5 of 50

İf 50.2/5

[tex]50. \frac{2}{5} = 50 \div 5 = \frac{2}{5 \div 5} = 10.2 = 20[/tex]

İf 2/5 /50

[tex] \frac{\frac{2}{5} }{50} = \frac{2}{5} . \frac{1}{50} = \frac{2 \div 2}{5} . \frac{1}{50 \div 2} = \frac{1}{5} . \frac{1}{25} = \frac{1}{125} = 0.008[/tex]

Answer:

Step-by-step explanation:

Make this an expression

12,400x1 1/5

Now, Solve this expression

-make 1 1/5 an improper fraction

12,400x 6/5

-multiply the numerators by the numerators and the denominators by the denominators... remember that a whole number's decimal is always 1

12,400/1 x 6/5

12,400x6= 74400

1x5=5

74400/5= 14880

Is 14880 less than or greater than 12400? It is greater.

Answer:

p - 25

Step-by-step explanation:

Given :

Discount = 25 dollars off

Regular price = p

Sale price in dollars :

Regular price - discount

p - 25

• Solution:-

➪ 5 - x - 3 = 0

➪ 5 - 3 - x = 0

➪ 2 - x = 0

➪ 2 = x

Hence, x = 2

Now,

✯ 3x²

➪ 3 × (2)²

➪ 3 × 4

Therefore, 3x² will be = 12.

Answer:

true because it have no common solution

Answer: false!

Step-by-step explanation:

To be parallel, the lines have to have the same slope. The slope for line a is 5, the slope for line b is -1/5. These lines are perpendicular.

Answer:

For an equation like:

y = a*x + b

a is the slope, and this is the rate of change of the function.

For the case of the problem, we know that the equation represents the amount of oxygen in the spaceship as a function of time. Where as the time passes, the quantity of oxygen decreases.

Then the slope is the rate of change that tells how the quantity of oxygen changes as time passes. Then the slope is the amount of oxygen that is consumed per unit of time.

Answer:

If my calculations are correct it would be 6,168 cups of strawberries

Step-by-step explanation:

If it’s 8 times the amount of them combined then you add all of the other fruit together and then multiply by 8 giving you:

323+214+234=771

771*8=6,168 cups of strawberries.

Only in math would someone need that much fruit

Answer:

44

Step-by-step explanation:

Substitute the values for the variables.

6x2 = 12

So the answer is A

Answer:

7.5cm

Step-by-step explanation:

the method is shown above

YES

Base=b

Height= h

Area 1=A1=1/2*b*h

Base=b

Height= 4h

Area of triangle 2=A2=1/2*b*4h

A2/A1= (1/2*b*4h)/(1/2*b*h)

= (1/2*b*4h)/(1/2*b*h)

=4/1

Ratio of heights =h2/h1= 4/1

Ratio of areas =A2/A1= 4/1

They are proportional.

Answer:

Compare x^2 +y^2-8x-6y=75 with the general circle equation x^2+y^2 -2ax-2by+c=0

-2a =-8 And -2b=-6

a=4 b=3

c=-75

To find the radius use the equation

r^2=a^2+b^2-c

r^2=4^2+ 3^2-(-75)

r^2=25+75=100

r=10(radius is always positive)

Hence the center is (4,3) and radius 10

Answer:

Step-by-step explanation:

Water in a 10 gallon tank is draining at a rate of 2 gallons per hour.

= 10 - 2x

Water in a separate tank is filling at a rate of 4 gallons per hour.

= 10 + 4x

Equating both Equations together

10 - 2x = 10 + 4x

10 - 10 = 4x - 2x

How long until the tanks have the same amount of water?

Let the time = x
