Number of cups of peanuts needed to make 49 cups of the mixed nuts snack is 21 cups

The ratio of cups of almonds to cups of peanuts in a mixed snack = 4 : 3

Number of of cups of almonds = 4x

Number of cups of peanuts = 3x

Total number of cups of mixed nuts snack = 49 cups

Then the equation will be

4x + 3x = 49

Add the like terms

7x = 49

x = 49 / 7

x = 7

Number of cups of almonds needed = 4x

= 4×7

= 28 cups

Number of cups of peanuts needed = 3x

= 3×7

= 21 cups

Hence, number of cups of peanuts needed to make 49 cups of the mixed nuts snack is 21 cups

Points of interval A (-1,-3) and (-2,-6)

Points of interval B is (1,1) and (2,-1)

How to find Piecewise function?

Determine which of the following intervals (or inequalities) the input belongs to before evaluating a piecewise function at any given input. The function specification for that specific interval can then simply be updated to reflect the new input.

[tex]f(x)=\left \{ {{3x, if x\leq -1} \atop {-2x+3, if 0 < x < 4}}\atop {2, if x\geq 4}\right.[/tex]

lets take 3x as Interval A

-2x+3 as interval B

and 2 as interval C

Now lets calculate the interval A

f(x)=3x

as x≤-1

∴f(-1) = 3(-1)

       =(-3)

∴ point is (-1,-3)

∴f(-2) = 3(-2)

       =(-6)

∴ point is (-2,-6)

Now lets calculate the interval B

f(x)=-2x+3

as 0<x<4

∴f(1) = -2(1)+3

       =-2+3

      =1

∴ point is (1,1)

∴f(2) = -2(2)+3

       =-4+3

       = -1

∴ point is (2,-1)

The linear equation to represent the hours that Yuson has left to do after x days is 16 - 2x.

From the information, Yuson has to do Y hours of community service.

She works two hours every day, so service hours in x days = 2x

Remaining service hours after x days = y-2x

Also we have after 8 days , Yuson has completed half of her required community serivice. Therefore,

8 = y/2.

Answer:-2/5

Step-by-step explanation: due to them being negative we are using the simple thing of which number is closer to zero. -2/5 is closer which means that is it greater. -2/5 would be ahead on number line if you need a visualization

Answer:

-3/8

Step-by-step explanation:

1) Work out the options you are given

2) Find which one is greater

As the numbers are decimal the 'seemingly greater number' might actually be the smaller one.

To find out which decimal is greater you can easily plot them into a number line.

The number that is further to the left is smaller and the number closer to the right is higher!

If we were to plot the numbers one a number line the -0.375 would be closer to the right meaning it is greater.

HINTS:

To make it easier to divide minus numbers, at first completely forget about the minus (you can plug it back in at the end).

For example, if you were given -2/5 get rid of the minus to get 2/5 and from this we can easily figure out 2 ÷ 5 which would give us 0.4.

At the point where you have your final number you can add the - back in making it -0.4

Hope this helps, have a great day!

The best estimate of this amount of water is [tex]3*10^{7}[/tex].

Given:

At an elevation of 1221. 4 feet, lake mead will hold 28,945,000 acre-feet of water.

So, the amount of water that is in the lake will be 28,945,000 acre-feet which is estimated to be 30000000 acre-feet of water.

Because the nearest estimate to 28945000 is 30000000.

= 30000000

= 300000*[tex]10^{2}[/tex]

= 30000*[tex]10^{3}[/tex]

The qualified student loan interest deduction in 2021 is $37500.

Adjusted gross income is an individual's total gross income less specific deductions in the United States income tax system. It is used to compute taxable income, which is AGI minus personal exemption and itemized deduction allowances. AGI is more important than gross income for most individual tax purposes.

AGI is calculated by taking your gross income and subtracting certain "above the line" deductions. 401(k) contributions, health savings account contributions, and educator expenses are common examples of deductions

As per Law, a maximum of $2,500 will be allowed to be deducted from the Income. Thus the following would be the solution.

The equation of the lines passing the points and parallel to the equations ( 7,-3) , 3y = 12x + 5  (-5, -2), y + 3x = 10 is as follows:

The equation of a line can be represented in different form such as standard form, general form, slope intercept form and point slope form. Therefore, let's represent the line in slope intercept form.

The equation of a line in slope intercept form is as follows:

y = mx + b

where

Parallel line shave the same slope.

Hence,

( 7,-3) , 3y = 12x + 5

y = 4x + 5 / 3

slope is 4

The equation of the line is y = 4x + b. let's find the y-intercept using (7, -3).

-3 = 4(7) + b

b = -3 - 28

b = - 31

Hence, y = 4x  - 31

(-5, -2), y + 3x = 10

y = -3x + 10

slope = -3

Therefore, let's find y-intercept using (-5, -2)

-2  = 15 + b

b = -2 -15

b = - 17

Answer:

y = 5x -2

Step-by-step explanation:

The 5 is the slope.  It is the change in y over the change in x.  As the x changes by 1, the y changes by 5.

The -2 is the y intercept.  This is at the point (0,-2)  The -2 is the y intercept.

The order of the quotient from smallest to largest is given as follows:

42.6/70, 426/70, 42.6/0.07, 42.6/0.07.

A quotient is given by the division of two terms a and b, that is:

a / b.

From this, we have that the dividend a and divisor b are inverse proportional, that is:

There are three divisions with the same term a, hence they are ordered, from smallest to largest, as follows:

42.6/70, 42.6/0.07, 42.6/0.07.

(the smallest the value of b, the largest the quotient).

The final quotient is:

426/70.

Dividing by 10 to have an equivalent value of a, we have that:

426/70 = 42.6/7.

Which is the second largest value of b, hence the second smallest quotient.

y = -0.727

The given data

4x - 2y = 8   (1)

5x + 3y = 6   (2)

multiplying (1) by 3/2 and adding the result to (2)

The turning point of the parabola is the point (2, - 9).

Quadratic equations represents parabolae and the vertex of the parabola represents the turning point as the slope of the curve changes its sign, from positive to negative or viceversa. The vertex can be derived by the vertex form of the equation of the parabola:

y - k = C · (x - h)²

Where:

Since the quadratic equation has two real coefficients, we need the location of two points on Cartesian plane to find one solution. First, create the system of linear equations:

b = - 5                                      (1)

5 · a + b = - 25                        (2)

Second, substitute b in (2) and clear a:

5 · a - 5 = - 25

5 · a = - 20

a = - 4

Third, write the quadratic equation:

y = x² - 4 · x - 5

Fourth, transform the equation into vertex form by completing the square:

y + 9 = x² - 4 · x + 4

y + 9 = (x - 2)²

Fifth, write the vertex of the parabola:

(h, k) = (2, - 9)

The point (2, - 9) represents the turning point of the parabola.
