Sasha Ruby and Mario each have 1 3 / 4 cups of flour.can they make a recipe for bread that needs 5 cups of flour

saw5 [17]

Each of them have 1 3/4 cups of flour, so together they have 2 x 1 3/4 cups. Turn the mixed number into an improper fraction in order to multiply it. 1 3/4 = 4/4 + 3/4 = 7/4. Multiply 7/4 x 2 = 7/4 x 2/1 = 7(2) / 4(1) = 14/4, which simplified equals 3 1/2 because 14/4 = 3 r2, or 3 2/4, which equals 3 1/2. So together they have a total of 3 1/2 cups of flour. Because 3 /12 is less than 5, they do not have enough cups of flour to make the recipe.

If anyone can answer these I will love you forever (congruence and similarity)

avanturin [10]

Answer:

Step-by-step explanation:

1. Corresponding Angles

<1 and <5

<2 and <6

<3 and <7

<4 and <8

They are equal in measure because corresponding angles are always equal to each other which means that they are congruent.

2. Alternate Interior Angles

<3 and <6

<4 and <5

They are always equal to each other because alternate interior angles are always congruent.

3. They are alternate exterior angles which means that the angles are always congruent.

4. <8 will be 73 degrees which is the same as <4 because they are corresponding angles and they are always congruent.

5. Angle 6 will be 107 degrees because they are alternate interior angles and they are always congruent.

A youth organization collected nickels and dimes for a charity drive. By the end of the 1-day drive, the youth had collected $63

uysha [10]

Let, the numbers of nickels be x.

Given, there were 5 times as many dimes as nickels.

So, the number of dimes = 5x

We know that 1 nickel = $(0.05)

So x nickels = $(0.05x)

Also we know that 1 dime = $(0.1)

So 5x dimes = $(0.1 ×5x) = $(0.5x)

Given total value of dimes and nickels at the end of day 1 is $63.80

So we can write the equation

$0.05x+0.5x = 63.80$

$0.55x = 63.80$

Now we to find x, we have to move 0.55 to the other side. As 0.55 is multiplied there so to move it we need to divide it to both sides.

$0.55x/0.55 = 63.80/0.55$

$x = 116$

So we have got the number of nickels = 116

Number of dimes = 5x = 5(116) = 580

So we have got the required answer.

Number of nickels = 116, number of dimes = 580.

Write the equation in slope-intercept form. What are the slope and y-intercept? -12x-4y=10

siniylev [52]

Answer:

y = -3x -2.5

slope: -3

y-intercept: -2.5

Step-by-step explanation:

Solve for y.

-4y = 12x + 10 . . . . . add 12x to get the y-term by itself

y = -3x -2.5 . . . . . . .divide by the coefficient of y

The slope is the coefficient of x, -3.

The y-intercept is the constant, -2.5.
