8 0

Answer:

49.6cm

Step-by-step explanation: First you have to find the diameter of the circle by multiplying the radius by 2.

8x2=16

Then multiply 16 by 3.1

16x3.1=49.6

For their history project, students case to either write a report or give a presentation. Two fifth of the students wrote a repo

Gnesinka [82]

Answer: Yes. Dominic is correct

Step-by-step explanation:

We are informed that Two fifth of the students wrote a report. This also means that (2/5 × 100) = 40% = 0.4 wrote a report and 0.6 of the students gave a presentation.

From the decimals gotten, we can see that 0.6 is more than 0.4. Therefore, more students gave a presentation. This implies that Dominic is correct.

1/3x^2+2 what does the graph look like

Anna11 [10]

Answer:

The answer in the procedure

Step-by-step explanation:

we have

$\frac{1}{3}x^{2} +2$

This is a vertical parabola open upward with the the vertex at (0,2)

The vertex is a minimum

The y-intercept is the point (0,2) (value of y when the value of x is equal to zero)

The graph does not have x-intercepts, therefore the solutions of the quadratic equation are complex number

using a graphing tool

see the attached figure

1) Base of an isosceles triangle is five more than three times the equal sides and perimeter of the triangle is 75 cm. Find the

Lina20 [59]

Answer:

Equal sides of triangle = 14 cm

Base of an isosceles triangle = 47 cm

Step-by-step explanation:

Given:

Perimeter of the triangle = 75 cm

Base of an isosceles triangle = five more than three times the equal side

Find:

Lengths of isosceles triangle

Computation:

Assume;

Equal sides of triangle = a

So,

Base of an isosceles triangle = 3a + 5

Perimeter of the triangle = Base of an isosceles triangle + 2[Equal sides of triangle]

Perimeter of the triangle = 3a + 5 + 2[a]

Perimeter of the triangle = 5a + 5

75 = 5a + 5

5a = 70

a = 14

Equal sides of triangle = 14 cm

Base of an isosceles triangle = 3a + 5

Base of an isosceles triangle = 3(14) + 5

Base of an isosceles triangle = 42 + 5

Base of an isosceles triangle = 47 cm
