David has a garden with dimensions 11 feet long x 9 feet wide. He wants to enlarge the garden to an area of 126 square feet. How much farther will he need to extend the length of the garden to attain his desired area?

Answer:

d yess i think it is if right mark branly pleasee

Step-by-step explanation:

A.

[tex]3 = a \times b { }^{0} [/tex]

when it's to the 0 power it equals 1

[tex]b {}^{0} = 1[/tex]

[tex]3 = a \times 1 [/tex]

so therefore a=3

_______________

[tex]75 = a \times b {}^{2} [/tex]

replace a with 3

[tex]75 = 3 \times b {}^{2} [/tex]

divide 75 by 3 equalling 25

[tex]b {}^{2} = 25[/tex]

lastly find the square root

[tex] \sqrt{25} = 5[/tex]

there fore

________

b= 5

a= 3

Answer:

  a) (a, b) = (3, 5) or (3, -5)

  b) (a, b) = (2, 3)

Step-by-step explanation:

Generally, you solve systems like this by dividing one equation by the other. This gives you the value of the base (b). Substituting that into either equation gives you the scale factor (a).

__

a) Since b^0 = 1, you already have the solution for 'a': 3 = a. Substituting that into the second equation gives ...

  75 = 3b^2

  b = √(75/3) = √25 = 5

Since both exponents of b are even, there is no reason why b could not be -5.

Possible solutions: (a, b) = (3, 5) or (3, -5).

__

b) Dividing the second equation by the first gives b:

  [tex]\dfrac{54}{18}=\dfrac{a\cdot b^3}{a\cdot b^2}\\\\3=b \qquad\text{simplified}\\\\18=a\cdot3^2\qquad\text{substitute for b}\\\\\dfrac{18}{9}=a=2\qquad\text{divide by 9}[/tex]

The solution is (a, b) = (2, 3).

Additional comment

Usually, we're only interested in positive solutions for 'b'. Negative values usually only make sense when the exponent is an integer, as in the case of an exponential sequence.

Answer:

part A : Angles A, B, and C form a triangle. The sum of the angle measurements of a triangle is 180°. So, I can find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°.

part B: Angle A and angle B each measure 25°. Find the measurement of angle C by subtracting the measurements of angle A and angle B from 180°. The numerical expression for the measurement of angle C is 180° – 25° – 25°.

part C: The measurement of angle C is given by the expression 180° – 25° – 25°. So, angle C measures 130°.

part D:Angle L and angle C are supplementary angles. The sum of supplementary angles is 180°. So, I can find the measurement of angle L by subtracting the measurement of angle C from 180°.

part E: Angle C measures 130°. Find the measure of angle L by subtracting the measurement of angle C from 180°. The numerical expression for the measure of angle L is 180° – 130°.

part F: The measurement of angle L is given by the expression 180° – 130°. So, angle L measures 50°.

Answer:

part a is 54            part b is 99

Step-by-step explanation:

72 x ? =3888

x=54

374 is the perimeter. You have a side that is 88cm so the opposite side will be 88 cm as well. 374-176=198

so between the last 2 sides we have 198. The sides will be equal so you just divide it by 2  

so the top and bottom of the rectangle are 99 and both sides are 88

Explanation:

This tent is a triangular prism. We have two congruent triangles in front and back. Let's stand the triangular prism up so that the triangle forms the base, or floor, of this figure.

The area of the base triangle is 5*4/2 = 20/2 = 10 square feet. I used the formula base*height/2 to get the area of a triangle.

Once we know the area of the base of the prism, we multiply that by the height of the prism, which is the 8 ft. So we get 10*8 = 80 cubic feet of volume.
