Reema and Sohini bought (x^2 - 9) mangoes.They divided into (x+3) groups.Each group has three rotten mangoes.How many good

Mathematics

Gemiola [76]3 years ago

Answer:

x - 6

Step-by-step explanation:

divide number of mangoes bought by number of groups, that is

\frac{x^2-9}{x+3}

= \frac{(x+3)(x-3)}{x+3} ← numerator is difference of squares

cancel the factor (x + 3) on numerator/denominator

number in each group = x - 3

subtract 3 rotten mangos from group for good mangoes

good mangoes = x - 3 - 3 = x - 6

Ivory created a scaled copy of rectangle A.
9966 [12]

The scale factor that Ivory used to create their scaled copy is;

<u><em>Scale is 1 interval on graph represents 4 units of the rectangle. This is 1:4 ratio.</em></u>

  • From the given image, we can see that the y-axis of the rectangle has 3 intervals while the x-axis has 1 intervals

  • Now, from the image, we are told that the area of the scaled copy is 48 square units.

What this means is that the area of the triangle she is trying to represent with that graph is 48 square units.

  • Now, if one interval of the graph is x-units, then it means;

length; y-axis = 3x units

width; x-axis = x units

  • Area of a rectangle is given by;

Area = Length × width

Thus;

3x * x = 48

3x² = 48

x² = 48/3

x² = 16

x = √16

x = 4

<em>Thus, 1 interval on the graph represents 4 units of the rectangle.</em>

50 Points What is the value of r? 6.4r−5.9r=−3.25 Question 1 options: A -6.5 B 6.5 C -3
Oliga [24]

Answer:

Option A. -6.5

Step-by-step explanation:

we have

6.4r-5.9r=-3.25

Solve for r

That means ---> isolate the variable r

Combine like terns left side of the equation

0.5r=-3.25

Divide by 0.5 both sides

0.5r/0.5=-3.25/0.5

r=-6.5

Find the lateral and total surface area for the cone. If necessary, round to the nearest tenth and leave the
bija089 [108]

9514 1404 393

Answer:

  • 262.2π cm²
  • 392.16π cm²

Step-by-step explanation:

The lateral surface area is the product of half the circumference, and the slant height:

  LA = πrh = π(11.4 cm)(23 cm) = 262.2π cm²

The total surface area adds the area of the base to that:

  A = πr² +LA = π(11.4 cm)² +262.2π cm² = (129.96 +262.2)π cm²

  A = 392.16π cm²
