Answer:

44.4 meters

Step-by-step explanation:

Using 1 foot = 30 cm

convert 148 feet to centimeters by multiplying.

148ft × 30cm/1ft

= 148 × 30

= 4440 cm

Then convert cm to meters by dividing by 100.

1 meter = 100cm

4440cm × 1m/100cm

= 4440/100

= 44.4m

148 feet is 44.4m

Answer:

3 times as great

Step-by-step explanation:

The most amount of water is 3/4 full

The least amount of water 1/4 full

To get from 1/4 to 3/4, you multiply by 3:

[tex]\frac{1}{4} * \frac{3}{1} = \frac{3}{4}[/tex]

(I made 3 into 3/1 to show how you multiply across easier)

Answer:

(x - 6)^2 = 0 or (x + 2)^2 = 0

Take the square root of both sides:

x - 6 = 0 or (x + 2)^2 = 0

Add 6 to both sides:

x = 6 or (x + 2)^2 = 0

Take the square root of both sides:

x = 6 or x + 2 = 0

Subtract 2 from both sides:

Answer: x = 6 or x = -2

Step-by-step explanation: the answer is x= 6  or = -2

3. correct

4. [tex]a^{8}b^{10}c^{15}[/tex]

Step-by-step explanation:

When dividing a monomial by another monomial, we divide the coefficients and apply the quotient law of exponents, x m ÷ x n = x m – n to the variables. If both the monomials have negative coefficients, the negative signs cancel out and the answer so obtained will be having a positive coefficient only.

For example, the binomial 2x +4 can be multiplied by the monomial 4x so that (2x) (4x) equals 8x2 and 4·4x equals 16x, using the distributive property. Therefore, (2x +4) (4x) equals 8x2 + 16x.Mar 15, 2016

Use the Quotient Property. When we divide monomials with more than one variable, we write one fraction for each variable. Use fraction multiplication. Simplify and use the Quotient Property.

Answer:

B) x-5y=20

Step-by-step explanation:

y-y1=m(x-x1)

y-(-5)=1/5(x-(-5))

y+5=1/5(x+5)

y=1/5x+5/5-5

y=1/5x+1-5

y=1/5x-4

1/5x-4=y

5(1/5x-4)=5y

5/5x-20=5y

x-20=5y

x-5y=20

Answer:

Step-by-step explanation:

Product = 20

Sum = 12

Factors = 2 , 10    {2*10 = 20 & 2+10 = 12}

x² +12x + 20 = x² + 2x + 10x + 20    {Split the middle terms using the factors}

       = x( x + 2) + 10(x + 2)

       = (x + 2)(x + 10)

Answer:

A semicircle is drawn with AC as diameter. If AB = BC = 7 cm, find the area of the shaded region. Take π = 22/7. 25. A circular field has perimeter 660 m.

Using the formula for area of circle and right angled triangle, we find that area of shaded region is  96[tex]cm^2[/tex].

Area of circle = [tex]\pi r^2[/tex]

where, r is the radius of circle.

Area of right angled triangle = [tex]\frac{1}{2} * base *height[/tex]

The area of shaded region is given by =

= area of semicircle with AB as diameter + area of semicircle with BC as diameter + area of triangle ABC - area of semicircle with AC as diameter

Now,

area of semicircle with AB as diameter =

AB = diameter  =  12cm

radius = 6 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 6^2 = 56.52[/tex]

area of semicircle with BC as diameter =

BC = diameter  =  16cm

radius = 8 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 8^2 = 100.48[/tex]

area of semicircle with AC as diameter =

AC = diameter  =  20cm

radius = 10 cm

area of semicircle = [tex]\frac{1}{2} \pi r^2 = \frac{1}{2} *3.14 * 10^2 =157[/tex]

area of triangle ABC =

AB = base = 12cm

BC  = perpendicular = 16 cm

area(ABC) = [tex]\frac{1}{2}*12*16 = 96[/tex]

The area of shaded region is given by = 56.52 + 100.48 + 96 - 157 = 96[tex]cm^2[/tex]

Answer:

9x + 36 = 63

Step-by-step explanation:

Let x represent the number of toys that each club member donated.

There are 9 students in a service club.

If each club member donated 4 children's books for the baskets, it means that the total number of books donated by the club members would be

9 × 4 = 36

If each club member also donated an equal number of toys. It means that the total number of toys donated by the club members would be

9 × x = 9x

A total of 63 items were collected for the baskets. Therefore, the linear equation that you can use to find how many toys each club member donated would be

Janae and Jerome each have either 3, or 4 or 5 marbles. Option C, D and E are correct.

Given that the number of marbles has:

Janae = m

Jerome  = m

Gwen = 4(m+2)

John = 8m+4

John has more marbles than Janae, Jerome, and Gwen combined, So this can be written as,

[tex]8m+4 \geq m + m + 4(m+2)[/tex]

[tex]8m+4\geq 2m + 4m+8[/tex]

[tex]8m+4 \geq 6m+8[/tex]

[tex]2m\geq 4[/tex]

[tex]m\geq 2[/tex]

It means that the value of m is greater than 2, it can be 3, 4 or 5.

Hence we can conclude that Janae and Jerome each have either 3, or 4 or 5 marbles. Options C, D and E are correct.
