Answer:

4/9 cup of sugar

Step-by-step explanation:

[tex]\frac{1}{3} cup of sugar= \frac{3}{4} cup of flour[/tex]

[tex]? cup of sugar=1 cup of flour[/tex]

so crisscross them and finally you'll get

1/3*4/3=4/9

For 1 cup of flour, 4/9 cups of sugar is needed.

Ratio is a quantitative relation between two amounts showing the number of times one value contains or is contained within the other. A statement expressing the equality of two ratios A:B and C:D is called a proportion. We can express proportion as -

A : B ∷ C : D

AND

A x D = B x C

Product of extremes equal to product of means.

Given is a recipe that requires 1/3 cup of sugar for every 3/4 cup of flour.

Now -

For 1/3 cup of sugar = 3/4 cup of flour is needed.

For 1 cup of flour = (1/3)/(3/4) cups of sugar = 1/3 x 4/3 = 4/9 cups of sugar is needed.

Therefore, for 1 cup of flour, 4/9 cups of sugar is needed.

Answer: 48 minutes

Step-by-step explanation:

If there are 7 people painting 7 walls, we can assume that 1 person is painting 1 wall. Altogether they can each paint in 48 minutes.

If there are 20 people painting 20 walls, it would also equal 48 minutes because each person can paint in that time.

Answer:

137 minutes.

2 hrs and 17 minutes

Step-by-step explanation:

The painting of each wall takes 6.85 minutes.

48 / 7 = 6.85.

therefore if there are 20 walls, it must take 20 people 2 hrs and 17 mins

20 x 6.85 = 137minutes.

The value of x from the expression is,

⇒ x = 1/4 (Y - 3)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The equation is,

⇒ Y = 4x + 3

Now, We can solve the expression for the value of x as;

⇒ Y = 4x + 3

Subtract 3, we get;

⇒ Y - 3 = 4x + 3 - 3

⇒ Y - 3 = 4x

Divide by 4;

⇒ (Y - 3) / 4= 4x/4

⇒ (Y - 3)/4 = x

⇒ x = 1/4 (Y - 3)

The graph that represents the total monthly cost at the gym as a function of the number of visits in a month is shown by option A)

The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept

And y - y₁ = m ( x - x₁ )

y = y-coordinate of second point

y₁ = y-coordinate of point one

m = slope

x = x-coordinate of second point

x₁ = x-coordinate of point one

The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )

Given data ,

Based on the number of visits each month, a gym provides three different levels of membership.

Let the monthly visits be 'a' and the overall expense be 'b'. The following will be the appropriate graph showing the total monthly cost of the gym as a function of monthly visits:

A) For the interval of a = [0,12]

The value of b is given by:

b = 5a + 15

when a = 0 in the above equation.

b = $15

when a = 12 in the above equation.

b = 60 + 15

b = $75

The interval of b = [15,75]

B)

For the interval of a = [12,16]

The value of b is given by:

b = 4a + 32

when a = 12 in the above equation.

b = 48 + 32

b = $80

when a = 16 in the above equation.

b = 64 + 32

b = $96

The interval of b = [80,96]

C)

For the interval of a = [16,24]

The value of b is given by:

b = 3a + 42

when a = 16 , we get

b = 48 + 42

b = $90

when a = 24 in the above equation , we get

b = 72 + 42

b = $114

The interval of b = [90,114]

Hence , the graph is represented by graph A

Answer:

y-4=100 and 100=y-5

Step-by-step explanation:

Because the addition property of equality is: The property stating that adding the same number to both sides of an equation does not change the equation.

Equations are used to represent equal expressions

The equivalent equation of y + 4 = 100 is 4 + y = 100

The equation is given as:

y + 4 = 100

Rewrite the equation as follows:

4 + y = 100

Hence, the equivalent equation of y + 4 = 100 is 4 + y = 100

Answer: The area of this hub cap is about  470.46  square centimeters.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Replacing with the values given:

76.87 = 2 (3.14) r

Solving for r (radius)

76.87/ (2x 3.14) =r

r = 12.24 cm

To find the Area:

A = 3.14 (12.24)^2

A = 470.46 cm2

If the circumference of the hub is smaller, the area is also smaller because it means that the radius of the circle decreases.

Answer:

t=16.2 years

Step-by-step explanation:

A=p(1+r/n)^nt

A=$20100

P=$6500

r=7%=0.07

t=?

t=ln(A/P)/n {ln(1+r/n)}

=ln(20100/6500) / 4{ln(1+0.07/4)}

=ln(3.0923)/4{ln(1+0.0175)}

=ln(3.0923)/4{ln(1.0175)}

Step-by-step explanation:

Assuming you mean the perimeter is 4 2/15, the sum of the lengths of the two equal sides is ...

  4 2/15 - 4/5 = 4 2/15 - 12/15 = 4 -10/15

Then either of the remaining sides is half this value, or ...

  (4 -10/15)/2 = (4/2) -(1/2)(10/15) = 2 -5/15 = 1 10/15 = 1 2/3

Each of the remaining sides has length 1 2/3.

============================================================

Explanation:

Starting at (4, -1) and moving four units up will have us arrive at (4, 3). We add 4 to the y coordinate and keep the x coordinate the same. The algebraic rule is stated as [tex](x,y) \to (x,y+4)[/tex].

Next, we reflect over the y axis. This will have us flip the sign of the x coordinate while keeping the y coordinate the same. The algebraic rule for this kind of reflection is [tex](x,y) \to (-x,y)[/tex]. The point (4,3) reflects over the y axis to get to (-4,3)

So we started at (4, -1), then moved four units up to get to (4,3) and then reflected over the y axis to get to (-4, 3) which is the final stop.

This is all shown in the diagram below.
