We can Notice from the Figure that X is the Centroid of the Given Triangle.

We know that Centroid divides each Median in the Ratio 2 : 1

From the Figure : CH is one of the Median

Given the Length of CH is 33 ft

X divides the Median CH in the ratio 2 : 1

Let us Divide the Median CH into 3 Equal Parts

Length of Each Part of 3 Equal Parts = $\frac{33}{3} = 11$

⇒ Length of CX = 2 × 11 = 22 ft

<h3>Answer: 5 cakes</h3>

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

Explanation:

Let's start off converting the mixed number 12 & 1/4 to an improper fraction.

$a \frac{b}{c} = \frac{a*c+b}{c}\\\\12 \frac{1}{4} = \frac{12*4+1}{4}\\\\12 \frac{1}{4} = \frac{49}{4}\\\\$

Do the same for the other mixed number 2 & 1/3.

$a \frac{b}{c} = \frac{a*c+b}{c}\\\\2 \frac{1}{3} = \frac{2*3+1}{3}\\\\2 \frac{1}{3} = \frac{7}{3}\\\\$

-----------------------

From here, we divide the two fractions. I converted them to improper fractions to make the division process easier.

$\frac{49}{4} \div \frac{7}{3} = \frac{49}{4} \times \frac{3}{7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{49\times 3}{4\times 7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{7\times 7\times 3}{4\times 7}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{7\times 3}{4}\\\\\frac{49}{4} \div \frac{7}{3} = \frac{21}{4}\\\\$

The last step is to convert that result to a mixed number.

$\frac{21}{4} = \frac{4*5+1}{4}\\\\\frac{21}{4} = \frac{4*5}{4}+\frac{1}{4}\\\\\frac{21}{4} = 4+\frac{1}{4}\\\\\frac{21}{4} = 5 \frac{1}{4}\\\\$

Note that 21/4 = 5.25 and 1/4 = 0.25 to help check the answer.

-----------------------

Therefore, she can make 5 cakes. The fractional portion 1/4 is ignored since we're only considering whole cakes rather than partial ones.

Please help, preferably in the next half an hour.

Answer:

For the first question the correct form would be B. It would be 6(p-3)=42. For the second question the answer would be 10.

Step-by-step explanation:

For the first question B is correct because it's 3 dollars off which would be -3.

For the second question you would multiply 6 with p and 6 with -3. This would equal to 6p-18. This would make the equation 6p-18=42. You would then add 18 to 42, which equals 60. Finally you would divide 60 by 6, which equals 10, which is your answer.

the length of a rectangle is 4 feet more than its width. The area of the rectangle is 60ft^2. Find the length and width of the r

liubo4ka [24]

Answer:

10 and 6

Step-by-step explanation:

Let A be the area of the rectangle, w the width and L the length

● A = w*L

The length is 4 feet more that the width so L = w+4

● A = w ×(w+4)

● A = w^2 + 4w

The area is 60 ft^2

● w^2 + 4w = 60

Substract 60 from both sides

● w^2 + 4w - 60 = 0

This a quadratic equation

We will solve it by graphing it

The solution are 6 and -10 since the graph intersect with the x-axis in those points (pictures below)

The width is 6 feet long since it is a distance and a distance is always positive.

● w = 6

● L = w + 4

● L = 6 + 4

● L = 10

The width is 6 feet and the length is 10 feet

Identify the type of conic section that is represented by the equation y^2- 1 = 4(x-7). DUE IN 2 HOURS, will give BRAINLIEST! A.

Elenna [48]

Answer:

Solution : Parabola

Step-by-step explanation:

As you can see only one variable is square in this situation, so it can only be a parabola. We can prove that it is a parabola however by converting it into standard form (x - h)^2 + (y - k)^2.

$y^2-1=4\left(x-7\right) = y^2-1=4\left(x-7\right)$

Respectively it's properties would be as follows,

$\left(h,\:k\right)=\left(\frac{27}{4},\:0\right),\:p=1$
