Answer:

9 tablespoons of hot sauce

27 tablespoons of ketchup

Step-by-step explanation:

We know that Jen uses 3x as many tablespoons of ketchup as to hot sauce. We know she is making 36 tablespoons dipping sauce total.

SO, we make the equation x + 3x = 36

we group like terms and have 4x = 36

we need to divide both side by 4 and get 9

this means that we use a total of 9 tablespoons of hot sauce and 27 tablespoons of ketchup.

Answer:

225

Step-by-step explanation:

The total money spent on a pass and lunch for each student is $850.14.

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division.

here,

As mentioned in the question, Passes for 28 pupils and 4 teachers cost the school $778.88 and the school also spends $241.64 on lunch for kids only.

Total number of person  = 28 + 4
                                     = 32
Cost per pass = 778.88 / 32
                     = $24.34
Total passes of students = 25 × 24.34 = 608.5
Total spend on lunch of student = 241.64
Total spend on lunch = 241.64 + 608.5 = $850.14

Answer:

$14000 was invested at 10%

$12500 was invested at 14%

Step-by-step explanation:

We'll need a system of equations to find the amounts invested at 10% and at 14%

First equation:

amount invested at 10% + amount invested at 14% = total amount invested.

Thus, our first equation is x + y = 26500

Second equation:

interest earned at 10% + interest earned at 14% = total interest earned

Thus, our second equation is 0.1x + 0.14y = 3150

Method to solve:  We can solve using substitution by isolating x in the first equation.  Then we must substitute the resulting equation for x in the second equation.  This will allow us to first solve for y:

Step 1 (Isolating x in first equation):

(x + y = 26500) - y

x = -y + 26500

Step 2 (Plugging in x = -y + 26500 for x in 0.1x + 0.14y = 3150 to solve for y):

0.1(-y + 26500) + 0.14y = 3150

-0.1y + 2650 + 0.14y = 3150

0.04y + 2650 = 3150

0.04y = 500

y = $12500

Step 3:  Now we can plug in 12500 for y in the second equation in our system to find x:

x + 12500 = 26500

x = $14000

Thus, the amount invested at 10% is $14000 while the amount invested at 14% is 12500

Optional Step 4:  We can check that we've found the correct investment amounts by plugging in 14000 for x and 12500 for y in both equation in our system and checking that we get 26500 and 3150 respectively:

Checking solutions for first equation:

14000 + 12500 = 26500

26500 = 26500

Checking solutions for second equation:

0.1(14000) + 0.14(12500) = 3150

1400 + 1750 = 3150

3150 = 3150

The equation of the line perpendicular to 7x+5y = 4 is y = 5/7(x) -15/7. The equation of the line parallel to 7x+5y = 4 is  y = -7/5(x) -53/5

Given that: the line is perpendicular/parallel to the line 7x+5y = 4 and it passes through (−4,-5)

The slope-intercept form of a straight line is:

y = mx + c

where m is the slope and c is the y-intercept

For perpendicular case:

When the two lines are perpendicular, the product of their slope is -1 i.e.

m₁ x m₂ = -1

where m₁ and m₂ represent the slope of the lines

Let the slope of the given line be m₁ and the slope of the unknown line be m₂

Line1(given):

7x+5y = 4  => y = (-7/5)x + 4/5

Thus,  m₁ = -7/5

m₁ x m₂ = -1

-7/5 x m₂ = -1

m₂= 5/7

Line 2(unknown) with the point (−4,-5):

y = mx + c

-5 = 5/7 (-4) + c

-5 = -20/7 + c

c = -15/7

Thus, the equation of the line is y = 5/7(x) -15/7

For parallel case:

When the two lines are parallel, they have equal slope i.e. m₁ = m₂

Line1(given):

7x+5y = 4  => y = (-7/5)x + 4/5

Thus,  m₁ = -7/5

m₂= -7/5

Line 2(unknown) with the point (−4,-5):

y = mx + c

-5 = -7/5(-4) + c

-5 = 28/5 + c

c = -53/5

Thus, equation of the line is y = -7/5(x) -53/5

Answer:

y= In(x)-5

Step-by-step explanation:

The simplified expression for ( x - y ) ( x - y ) ( x - y ) is x³ - x²y - xy² + y³.

To simplify ( x - y ) ( x - y ) ( x - y ), we can expand the expression using the distributive property of multiplication. We can also simplify the expression by combining like terms.

In using the distributive property of multiplication, we multiply each term in the first set of parentheses by each term in the second set of parentheses. This gives us:( x - y ) ( x - y ) ( x - y ) = ( x(x - y) - y(x - y) ) ( x - y )= ( x² - xy - xy + y² ) ( x - y )= ( x² - 2xy + y² ) ( x - y )

Now we can further simplify the expression by combining like terms. We can use the difference of squares formula to simplify the second set of parentheses.( x² - 2xy + y² ) ( x - y ) = ( x - y ) ( x - y )²= ( x - y ) ( x² - 2xy + y² )= x³ - x²y - 2xy² + xy² - xy² + y³= x³ - x²y - xy² + y³

Therefore, the simplified expression is x³ - x²y - xy² + y³.

Summary: To simplify ( x - y ) ( x - y ) ( x - y ), we expand the expression using the distributive property of multiplication. We simplify the expression by combining like terms. We use the difference of squares formula to simplify the second set of parentheses. Finally, we simplify the expression further by combining like terms. The simplified expression is x³ - x²y - xy² + y³.

Step-by-step explanation:

The measure of angle a is determined as 30 degrees.

The measure of angle a is calculated by applying the following circle theorem as follows;

If line AB is the diameter of the circle, then angle ACB will be equal to 90 degrees.

The value of a is calculated as;

a + 2a = 90 (complementary angles sum up to 90 degrees since angle ACB is equal to 90 degrees)

3a = 90

divide both sides by 3;

3a/3 = 90 / 3

a = 30

No matter which direction an object is going in, speed is a scalar variable that quantifies how swiftly it is moving. The rate at which an object changes its position in a particular direction is measured by a vector quantity called velocity.

Speed: The amount of time it takes to cover a certain distance is stated in units like meters per second (m/s) or miles per hour (mph). For instance, a car's speed is 60 mph if it covers 60 miles in an hour.

Both the speed and direction of motion are included in the displacement per unit of time, which is stated in terms like meters per second (m/s) or miles per hour (mph). For instance, a car's velocity is 60 mph due north if it drives 60 miles in an hour in that direction.

In other words, velocity informs us on the direction and speed of an object's motion in addition to its speed.

Janet completed a 4 mile run yesterday in 30 minutes. We can calculate her running speed using the following data:

rate = distance/time = 4 miles/30 minutes = 0.1333 miles/minute

Today Janet ran for 45 minutes at the same pace. We can calculate how far she ran today using her rate:

Rate = Distance 45 minutes at a speed of 0.1333 miles per minute equals 6 miles.

Without explicitly solving for x, we can conclude that the solution to the equation 2^x - 2 = 8^4 is x = 12.

To solve the equation 2^x - 2 = 8^4 without explicitly solving for x, we can simplify the equation using exponent rules and observe the relationship between the numbers.

First, let's simplify the equation:

2^x - 2 = 8^4

We know that 8 can be expressed as 2^3, so we can rewrite the equation as:

2^x - 2 = (2^3)^4

Applying the exponent rule (a^m)^n = a^(mn), we can simplify further:

2^x - 2 = 2^(34)

Simplifying the right side of the equation:

2^x - 2 = 2^12

Now, we can observe that both sides of the equation have the same base, which is 2. In order for the equation to hold true, the exponents must be equal:

x = 12

Therefore, we may deduce that the answer to the equation 2x - 2 = 84 is x = 12 without having to explicitly solve for x.
