The base of a triangle is 5 times the height. If the area is 490 square feet, then what is the height of the triangle, in feet?

Step-by-step explanation:

Weight of all female giraffes = 5x kg

Weight of all male giraffes = 7y kg

Mean weight of all giraffes

[tex] = \frac{5x + 7y}{5 + 7} \\ \\ = \frac{5x + 7y}{12} \: kg[/tex]

The mean weight of all the giraffes, in terms of x and y, is calculated by adding the total weights of both female and male giraffes and then dividing by the total number of giraffes. The expression for the mean weight is (5x + 7y) / 12.

To find the mean weight of all the giraffes in terms of x and y, we must first calculate the total weight of female and male giraffes separately and then combine these totals to find the overall mean.

For the 5 female giraffes: Total weight = 5 × x = 5x kg

For the 7 male giraffes: Total weight = 7 × y = 7y kg

Then, we add these together to get the combined total weight: Combined total weight = 5x + 7y kg

Since there are 5 + 7 = 12 giraffes in total, we then divide the combined weight by the number of giraffes to find the overall mean weight.

Overall mean weight = (5x + 7y) / 12

Answer:

Option C. [tex]y=-x^2[/tex]

Step-by-step explanation:

we know that

We can reflect the graph of any function f(x) about the x-axis by graphing y=-f(x)

so

The rule of the reflection of a function f(x) across the x-axis is

(x,f(x)) ------> (x,-f(x))

In this problem we have

[tex]f(x)=x^{2}[/tex]

Applying the rule of the reflection across the x-axis

[tex](x,x^2) ----> (x,-x^2)[/tex]

therefore

The new equation of the quadratic function is

[tex]y=-x^2[/tex]

Answer:

1/24

Step-by-step explanation:

As you go fraction to the next fraction you divide by 2.

2/3 divided by 2 = 1/3

1/3 divided by 2 = 1/6

the rule is "divide by 2"

Final answer:

The next fraction in the sequence is 1/24, found by continuing the pattern of halving each successive fraction.

Explanation:

To determine the next fraction in the sequence 2/3, 1/3, 1/6, 1/12, we observe a pattern. The second fraction is half of the first, the third is half of the second, and the fourth is half of the third. By continuing this pattern, to find the next fraction, we need to take half of the last fraction in the sequence.

To solve the more difficult problem, multiply the numerator and denominator by a skillfully chosen factor: 1/2. For the fraction 1/12, we multiply both the numerator (1) and the denominator (12) by 1/2 to get our next fraction:

Therefore, the next fraction in the sequence is 1/2 divided by 6 which simplifies to 1/24.

Answer:

The answer is 11

Step-by-step explanation:

Answer:

Angle BDC is an inscribed angle.

The inscribed angle equals one half of the intercepted arc.

Therefore, the intercepted arc equals 130 degrees.

Step-by-step explanation:

The measure of BC should be 130 degrees.

The angle of d is 65 degrees:

Since angle of D is 65

So, the BC should be doubled i.e. 130 degrees.

Answer:

the sum interior angles of a triangleis equal to 180

so (x + 13) +(x +23) + 90 = 180

2x + 36 + 90 = 180

2x = 180 - 126

2x = 54

x = 27

Answer:

The correct answer would be 8x - 12.

Step-by-step explanation:

2 ( -6 + 4z)

= (2) ( -6 + 4z)

= (2) ( -6) + (2) (4z)

= 12 + 8z

= 8z - 12

Hope this helps!

Answer:

Expanded answer: 8z - 12

OR

Factored answer: 4(2z - 3)

Step-by-step explanation:

Solve using the distributive property. This is when you multiply the number outside the brackets by each number inside the brackets.

2(-6 + 4z)

= (-6)(2) + (4z)(2)        Multiply each number by 2

= -12 + 8z        When you can, try not to start with a negative number.

= 8z - 12        This is the answer in expanded form

Refactored:

"8z" and "12" have a GCF (greatest common factor) of 4. Take out "4" from the expression to factor.

8z - 12

= 4( 8z/4 - 12/4 )        Divide each term by 4.

= 4(2z - 3)         This expression is equivalent when you need it fully factored.

Answer:

the correct answer for x is 8

Step-by-step explanation:

since:     1/2 ((4) (8) - 8) + (3) (8) = 36

The correct value for x that makes the equation true is 8.

To solve the equation [tex]\( \frac{1}{2}(4x-8)+3x=36 \)[/tex], follow these steps:

1. Distribute the [tex]\( \frac{1}{2} \)[/tex] to both terms inside the parentheses:

[tex]\[ \frac{1}{2} \cdot 4x - \frac{1}{2} \cdot 8 + 3x = 36 \][/tex]

2. Simplify the equation by multiplying:

[tex]\[ 2x - 4 + 3x = 36 \][/tex]

3. Combine like terms:

[tex]\[ 5x - 4 = 36 \][/tex]

4. Add 4 to both sides of the equation to isolate the term with x:

[tex]\[ 5x = 36 + 4 \][/tex]

[tex]\[ 5x = 40 \][/tex]

5. Divide both sides by 5 to solve for x:

[tex]\[ x = \frac{40}{5} \][/tex]

[tex]\[ x = 8 \][/tex]

Answer:

24 cubic inches

Step-by-step explanation:

1 ft = 12 inches

convert all dimensions to inches

1/4 ft = 1/4 * 12= 3 inches

1/6 ft = 1/6 * 12 = 2 inches

1/3 ft = 1/3 * 12 = 4 inches

Volume of a box = L*W*H

= 3 * 2 * 4

= 24 cubic inches

Therefore 1/72 ft will be 1/72 * 12

= 1/6 inches

Answer:135 degrees

Step-by-step explanation: Pretend that the 2 circles are equal, and connect the lines that form the angle. You can draw a right triangle on the circle that is on the right, connecting 2 radii to form it. Then, because the two radii are of equal length, you know that it is a 45-45-90 triangle. Then draw a line that is from the top line and connect in to G. That line is perpendicular, so 45 degrees plus 90 degrees is 135 degrees. I hope this helps!

Question:

What is the value of x? Enter your answer in the box. 68mm 57mm 129.2mm

The image of the triangle is attached below:

Answer:

The value of x is 98mm

Explanation:

It is given that VT = 57, TK = 129.2, YK = 68 and VK = x

Now, we need to find the value of x.

We shall determine the value of x, using angle bisector theorem,

[tex]\frac{YK}{TK} =\frac{YV}{VT}[/tex]

Let us substitute the values, we get,

[tex]\frac{68}{129.2}=\frac{x-68}{57}[/tex]

Switch sides, we have,

[tex]\frac{x-68}{57}=\frac{68}{129.2}[/tex]

Multiply both sides by 57,

[tex]\frac{57(x-68)}{57}=\frac{68 *57}{129.2}[/tex]

Simplifying, we get,

[tex]x-68=30[/tex]

Adding both sides by 68, we have,

[tex]x=98[/tex]

Thus, the value of x is 98mm

[tex]T_n= ar^{n-1}[/tex]

[tex]\therefore T_9=ar^{9-1}[/tex]

Answer:

1) x = 25    2) x = 23; m∠CBD = 80 degrees

Step-by-step explanation:

1) 5x + 15 = 6x - 10           Set both equations equal to each other

- 5x         - 5x                  Subtract 5x from both sides

15 = x - 10

+ 10    + 10                       Add 10 to both sides

25 = x

2) 2x + 14 + x + 7 = 90         Set the equations equal to 90

   3x + 21 = 90                     Combine like terms

         - 21  - 21                      Subtract 21 on both sides

3x = 69                                 Divide both sides by 3

x = 23

Plug 23 into the equation

2(23) + 14 = 60

Answer:

[tex]8 {m}^{2} {n}^{3} - 24 {m}^{2} {n}^{2} + 4 {m}^{3}n = 4 {m}^{2} n(2 {n}^{2} - 6n + m)[/tex]

Step-by-step explanation:

The given expresion is

[tex]8 {m}^{2} {n}^{3} - 24 {m}^{2} {n}^{2} + 4 {m}^{3}n[/tex]

Observe that 4 is common to 8,-24, and 4

Observe also that, m²n is common to all the terms.

Hence the GCF is:4m²n

We factor the GCF to get;

[tex]8 {m}^{2} {n}^{3} - 24 {m}^{2} {n}^{2} + 4 {m}^{3}n = 4 {m}^{2} n(2 {n}^{2} - 6n + m)[/tex]

Answer:

D) 68 carnations & 32 roses

Step-by-step explanation:

First of all, we need to identify the parts of the problem that we already know.

1) The events committee bought a total of 100 flowers.

2) The events committee spent a total of $139 on the carnations and roses, combined.

3) One carnation costs $0.75

4) One rose costs $2.75

We can create a formula to find the price of the flowers:

(x times $0.75) + (y times $2.75)= $139

If we calculate it out, the only option that fits the equation is 68 carnations and 32 roses.

Answer:

Step-by-step explanation:

Equation 1

3x - 4y = 16

multiplying equation by 3

it becomes

9x - 12y = 48  ------------(A)

equation 2

2x + 3y = 5

multiplying equation by 4

8x + 12y = 20 -------------(B)

Now comparing equation A & B

17x = 68

x = 4

putting the value of x in equation 2

2(4) + 3y = 5

8 + 3y = 5

3y = -3

y = -1

So, solution is (4 , -1)
