The simple interest on birr 400 invested for 4 month was birr 12. What is the annual/yearly rate of interest

Answers

Answer 1

Answer:

9%

Step-by-step explanation:

Given data

Principal= 400

time= 4 months

r= 12%

SI= 12

SImeple interest

12=PRT/100

susbstitute

12= (400*r*4/12)/100

12SI= 400*r*0.333/100

12=133.2r/100

cross  multiply

1200= 133.2r

r= 1200/133.2

r= 9.009

Hence the rate is 9%

A triangle has side lengths of (3.76 + 1.7) centimeters, (1.36 + 1.1) centimeters,
and (7.1c +5.1) centimeters. Which expression represents the perimeter, in
centimeters, of the triangle?

Answers

Answer:

Step-by-step explanation:

our triangle has one length:     3.76+1.7=5.46

                           another side: 1.36+1.1=2.46

                            last side:        7.1+5.1=12.20

Perimeter is=5.46+2.46+12.20=20.12 cm

Mia and Mario specialize in producing the item in which she or he has a comparative advantage. Then they trade one pasta dish for one pizza.. Before specialization and​ trade, Mia and Mario produce 6 dishes of pasta and 6 pizzas an hour each. The total gains from specialization and trade are​ ___________

Answers

Answer:

6 pizza, 6 pasta

Step-by-step explanation:

Now from the question we can see that Mia has comparative advantage in Pasta production and Mario in Pizza production.

Now before they both specialized, Mia's production was 6 pizza, 6 pasta. Mario also was making 6 pasta, 6 pizza.

So in total both were making 12 pizza and 12 pasta.

After they had specialized, Mario's pizza production is 18 pizza and Mia's pasta production is 18 pasta.

So we have that mia is producing 6 more pizza, 18-12 = 6

and Mario is also producing 6 more pasta.

So there is net gain of 6 pizza and 6 pasta.

Answers

Answer:

c = 16g

Step-by-step explanation:

g = 1/16 c

Multiply both sides by 16.

16g = c

c = 16g

Answer:

c = 16g

Step-by-step explanation:

g=1/16c

This is an algebric equation that requires you to multiply both sides by 16.

g × 16 = 1/16c × 16

16g = c

plz plz plz help

Answers

Try using PhotoMath that should help you:)

Answer:

44° , acute angle

Step-by-step explanation:

Given

y = 8x + 12 ← substitute x = 4

y = 8(4) + 12 = 32 + 12 = 44°

Since 44° < 90° then angle y is acute

Marcel bought a new pair of inline skates. Each wheel on the skates is 41 millimeters in radius. Which shows the number of millimeters traveled in 5 full rotations of a wheel?

Answers

Length length radius of a wheel in an inline skates = 41 millimeters

Circumference of wheel = Millimeters traveled by the wheel in one rotation

(pi value = [tex] \tt\: \frac{22}{7} [/tex])

Circumference of wheel :

[tex] = \tt2\pi r[/tex]

[tex] =\tt 2 \times \frac{22}{7} \times 41 [/tex]

[tex] = \tt \frac{2 \times 22}{7} \times 41[/tex]

[tex] = \tt \frac{44 \times 41}{7} [/tex]

[tex]\color{plum} =\tt 257.71 \: mm[/tex]

Thus, the wheel will travel 257.71 mm in one rotation.

Distance traveled by the wheel in 5 rotations :

= distance traveled by the wheel in 1 rotation × 5

[tex] =\tt 257.71 \times 5[/tex]

[tex]\color{plum} = \tt\bold{1288.55 \: mm}[/tex]

[tex] =\tt \frac{1288.55}{10} \: cm[/tex]

[tex] \color{plum}=\tt 128.855 \: cm[/tex]

▪︎Therefore, the distance traveled by the wheel in 5 rotations = 1288.55 millimeters or 128.855 cm.

Answer:

Horizontal distance = 0 m and 6 m

Step-by-step explanation:

Height of a rider in a roller coaster has been defined by the equation,

y = [tex]\frac{1}{3}x^{2}-2x+8[/tex]

Here x = rider's horizontal distance from the start of the ride

i). [tex]y=\frac{1}{3}x^{2}-2x+8[/tex]

      [tex]=\frac{1}{3}(x^{2}-6x+24)[/tex]

      [tex]=\frac{1}{3}[x^{2}-2(3x)+9-9+24][/tex]

      [tex]=\frac{1}{3}[(x^{2}-2(3x)+9)+15][/tex]

      [tex]=\frac{1}{3}[(x-3)^2+15][/tex]

      [tex]=\frac{1}{3}(x-3)^2+5[/tex]

ii). Since, the parabolic graph for the given equation opens upwards,

    Vertex of the parabola will be the lowest point of the rider on the roller coaster.

    From the equation,

    Vertex → (3, 5)

    Therefore, minimum height of the rider will be the y-coordinate of the vertex.

    Minimum height of the rider = 5 m

iii). If h = 8 m,

    [tex]8=\frac{1}{3}(x-3)^2+5[/tex]

    [tex]3=\frac{1}{3}(x-3)^2[/tex]

    (x - 3)² = 9

    x = 3 ± 3

    x = 0, 6 m

    Therefore, at 8 m height of the roller coaster, horizontal distance of the rider will be x = 0 and 6 m
