Answers

Answer:

Hey can you show us the answer choices? Also to solve your equation you have to find out your slope so you’d have to solve the question given to you.

1. 5x-4y=12 (move the x)

2. -4y=12-5x (it’s negative 5 because you do the opposite of positive 5)

3. -4y=12-5x (divide the number in front of y from both sides)

4. Slope should be (5/4) and b should be 3

5. Equation should be y=(5/4)x+3

Find an equation of the circle that has center (-1,6) and passes through (-6,1)

Answers

Answer:

(x + 1)² + (y - 6)² = 50

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius.

The radius is the distance from the centre to a point on the circle.

Calculate r using the distance formula

r = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 1, 6) and (x₂, y₂ ) = (- 6, 1)

r = [tex]\sqrt{(-6+1)^2+(1-6)^2}[/tex]

  = [tex]\sqrt{(-5)^2+(-5)^2}[/tex]

  = [tex]\sqrt{25+25}[/tex]

  = [tex]\sqrt{50}[/tex]

(h, k ) = (- 1, 6 ), then

(x - (- 1))² + (y - 6)² = ([tex]\sqrt{50}[/tex] )² , that is

(x + 1)² + (y - 6)² = 50 ← equation of circle

Katie has a coin collection she keeps 7 of the coing in the box which is only 14% of her entire collection. What is the total number of coins in katie's collection

Answers

Answer:

x= 50

Step-by-step explanation:

7/x = 14/100

14x = 700

x = 50

the reason behind my calculations were to get the same ratios and because they gave us percentage and the actual number, we can set them; 14 percent 14/100, however, the 7/x is because we don't know the 100 percent of the coins which is what we look for. Therefore, you cross multiply and get x.

I hope this helped

14/100x = 7
0.14x = 7
X = 50 coins

Carlos says that if the numerators of two fractions are the same, you can compare the denominators to determine which

one is greater. Which statement best describes Carlos's idea?

Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.

Carlos is correct. If the numerators are the same, the fraction with the greater denominator will be greater.

Carlos is incorrect. If the numerators are the same, the fractions will be equal.

Carlos is incorrect. You cannot compare fractions using only the denominators even if the numerators are equal.

Answers

Answer:

Carlos is correct. If the numerators are the same, the fraction with the lesser denominator will be greater.

Step-by-step explanation:

I'll answer this question using the following illustration.

Let a fraction be:

[tex]\frac{1}{2}[/tex]

and another fraction

[tex]\frac{1}{4}[/tex]

Both numerators are 1. In other words, they are equal

When you compare the denominator, 2 and 4, the fraction with lesser denominator is greater

This is so because:

[tex]\frac{1}{2} = 0.5[/tex]

[tex]\frac{1}{4} = 0.25[/tex]

By comparison

[tex]0.5 > 0.25[/tex]

This analysis can  be used for any fraction as long as they have the same numerator

Brenda has two remote-controlled race cars painted blue and red, respectively.The blue car traveled 54 feet 4 secounds.The red car traveled 38 feet im 2 seconds.

Answers

Answer:

The red car is faster compared to the blue car.

The red car is faster by 5.5 feet than the blue car.

Step-by-step explanation:

The objective is to find which car is  faster and by how much

Given that:

The blue car traveled 54 feet in 4 seconds; &

The red car traveled 38 feet in 2 seconds.

Let us determine the number of feet traveled in each second for both cases.

For the blue car:

In 1 second, the car will travel = 54/4 feet

In 1 second, the car will travel = 13.5 feet

For the red car:

In 1 second, the car will travel = 38/2 feet

In 1 second, the car will travel = 19 feet

Thus, the red car is faster compared to the blue car.

The distance at which the red car is faster than the blue car = 19 feet - 13.5 feet

= 5.5 feet

We need to tell if process was done correctly. If not, explain and correct the error by showing your own work.

The steps given are:

[tex]\frac{2}{3} (6k - 9) + 8k - 2\\=4k - 9 + 8k - 2\\=12k - 11[/tex]

The price of gallons as per number of gallons.

1 gallon to $1.50

30 gallons to $45.00

$1.00 to 2/3 gallon

Finding cost of gallons

Accoring to the question, the price of two gallons of vinegar is $3.00. A chef need fifteen gallons of vinegar to make pickles.

As we know the price of two gallons of vinegar, we can find out price for any amount of vinegar by applying cross multiplication method.

Let's find out price of different amounts of gallons

The cost of two gallons of vinegar = $3.00

So, the cost of one gallon of vinegar = $3.00/2 = $1.50.

we find out that cost of one gallon of vinegar is $1.50.

Let's find the cost of other amount of gallons.

The cost of four gallons = ?

we know the cost of one gallon is $1.50, so the cost of four gallons is $1.50 × 4 = $6.00

This is how we can find out cost of other amount of gallons by multiplying number of gallons by the price of one gallon.
