Calculate simple interest :

Elodia [21]

Answer:

the simple interest in both cases is 200 and 756 respectively

Step-by-step explanation:

The computation of the simple interest is shown below:

As we know that

Simple interest = P × r% × t

a. Simple interest is

= 2,500 × 8% × 1

= 200

b. The simple interest is

= 4,200 × 6% × 3

= 756

Hence, the simple interest in both cases is 200 and 756 respectively

The sides of a triangle are in the ratio 5 : 12 : 13. What is the length of each side of the triangle if the perimeter of the tr

Ganezh [65]

Answer:

2.5, 6 and 6.5 inches.

Step-by-step explanation:

5 + 12 + 13 = 30

So the shortest side = 5/30 * 15 = 1/6 * 15

= 2.5 inches.

The longest = 13 / 30 * 15 = 13/2

= 6.5 inches,

and the third = 12/30 * 15

= 6 inches.

Evaulate 10^2 + 6 multiplied by 7 + 8

Alinara [238K]

Evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590

Step-by-step explanation:

We need to evaluate $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$

Solving:

$10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8\\=(10^2+6)\times(7+8)\\=(100+6)\times(15)\\=106\times15\\=1590$

So, evaluating $10^2 + 6 \,\,multiplied\,\, by\,\, 7 + 8$ we get 1590

WILL MARK BRANIEST: Write the equation of the line fully simplified slope-intercept form.

Ierofanga [76]

Answer:

y = 3x - 4

Step-by-step explanation:

Slope-intercept is defined <em>y = mx + b</em>

Where m = slope (change in y-coordinate/ change in x-coordinate)

and b = y-intercept (where the graph crosses the y-axis)

For every 1 unit the line moves horizontally... it travels 3 units vertically. Therefore the slope (m) equals 3/1 or 3

The line crosses the y-axis at -4. Therefore... the y-intercept (b) is -4

I hope this helps!

I need help with these 4 questions on my math homework! I have some examples with it but I still don't know how to do them... (S

lesya [120]

Step-by-step explanation:

For equation N°2

$-x-3 = 0\\$

Solving algebraically:

$-x + x -3 = x$ (Sum x on both sides of the equation)

$-3 = x\\$

Resolving graphically:

x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)

x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)

x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N° 4

$9x +3 = 0\\$

Solving algebraically:

$9x+3 -3 = -3$ (Sum -3 on both sides of the equation)

$9x =-3$

$\frac{9x}{9}=\frac{-3}{9}$ (divided by 9 on both sides of the equation)

$x =\frac{-3}{9}$ (simplifies the fraction)

$x =\frac{-1}{3}$

Resolving graphically:

x = 1 --------- 9 (1) +3 = 12 pt (1.12)

x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)

x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N°. 6.

$4x + 11 = 4x-24\\$

Solving algebraically:

$4x -4x +11 = 4x -4x-24$ (Sum -4x on both sides of the equation)

$11 = -24$ The equation is not met, the x are eliminated, therefore, it has solution

For equation N°. 8

$-6x +3 = -6x + 5\\$

Solving algebraically:

$-6x + 6x +3 = -6x + 6x +5$ (Sum 6x on both sides of the equation)

$3 = 5$ The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.
