Answer:

x=21/4

Step-by-step explanation:

1. combine like terms

-4+-7= -11  3x-2x=x

2. subtract x

5x-11=x+10

4x-11=10

3. add 11

4x=21

4. divide 21 by 4 = 21/4

Write the ratio in simplest form for area of pool/ area of yard
charle [14.2K]

Answer:

Option (C)

Step-by-step explanation:

From the map attached,

Area of the rectangular yard = length × width

Length of the yard = 10 units

Width of the yard = 8 units

Area = 10 × 8

        = 80 square yards

Since, pool is a composite figure of two rectangles,

Therefore, area of the pool = Area of large segment + Area of the small pool

= (5 × 6) + (3 × 3)

= 30 + 9

= 39 square units

Ratio of Area of the pool and area of yard = \frac{39}{80}

Therefore, Option (C) will be the answer.

Use Euclid’s algorithm to find the greatest common factor of the following pairs of numbers:
Black_prince [1.1K]

Answer:

The GCF (12, 78) is 6 and GCF (18, 176)   is 2.

Step-by-step explanation:

Step 1:

The greatest common factor of the number is defined as the factor of two or more numbers. The acronym of Greatest common factor is GCF.

(a)

GCF (12, 78)  

The greatest common factor of the two numbers 12 and 78 is calculated by Euclid’s algorithm as follows:

78=12\times6+6

12=6\times2+0

Therefore, the greatest common factor GCF is 6.

Step 2:

(b)

GCF (18, 176)  

The greatest common factor of the two numbers 18 and 176 is calculated by Euclid’s algorithm as follows:

176=18\times9+14

18=14\times1+4

14=4\times3+2

4=2\times2+0

Therefore, the greatest common factor GCF is 2.

Write the equation of a parabola that has a vertex of (-2,5.5) and passes through the point (-2.5,2.5).
vekshin1

The equation of a parabola that has a vertex of (-2, 5.5) and passes through the point (-2.5, 2.5) is  y=-12(x+2)^2+5.5

The vertex form of the equation of a parabola is:

y=a(x-h)^2+k

where (h, k) is the vertex of the parabola

(x, y) is the point that the parabola passes through

The vertex, (h, k) = (-2, 5.5)

The point, (x, y) = (-2.5, 2.5)

Substitute h = -2, k = 5.5, x = -2.5, and y = 2.5 into the equation to solve for a.

2.5=a(-2.5-(-2))^2+5.5\\\\2.5=a(-2.5+2)^2+5.5\\\\2.5-5.5=a(-2.5+2)^2\\\\-3=a(-0.5)^2\\\\-3=0.25a\\\\a = \frac{-3}{0.25} \\\\a = -12

Therefore, the equation of the parabola is:

y=-12(x-(-2))^2+5.5\\\\y=-12(x+2)^2+5.5
