The time taken to cover Suva to Sigatoka is 2 Hours and 30 Minutes.

We know that, Time taken = (Distance Covered)/(Average Speed)

Given that the car travelled from Suva to Sigatoka and travelled 125 Km.

Average speed is = 50 km/hr

So the time taken to cover the distance = 125/50 = 5/2 hr = 2 hours and 30 minutes.

Hence the time taken to cover Suva to Sigatoka is 2 Hours and 30 Minutes.

The price bid will be increased by 23% over the cost, according to the question.

What do you mean by percentage?

A percentage in mathematics is a number or ratio that is expressed as a fraction of 100. The abbreviations "pct.", "pct.", and occasionally "pc" are also used to indicate it, though the percent sign, "%," is most frequently used. A percentage has no dimensions and no standard measurement.

According to data in the given question,

We have given data:

Cost on the product you make is $112 per unit.

Bid amount $138 per unit,

Cost over the bid= $138-$112 = $26

Now, we need to determine the Percentage increase,

Percentage increase[tex]= \frac{26}{112}*100 \\[/tex]

= 23%

Therefore, the price bid will be increased by 23% over the cost.

When the perimeter of the rectangle is 70 in, the length and width are 19 and 16 inches.

It should be noted that the perimeter of a rectangle will be calculated as:

= 2(Length + Width)

In this case, the length of a rectangle is 3in longer than it’s width and the perimeter of the rectangle is 70 in.

Therefore, width = w

length = w + 3

The perimeter will be:

2(w + w + 3) = 70

2(2w + 3) = 70

4w + 6 = 70

Collect like terms

4w = 70 - 6

4w = 64

Divide

w = 64 / 4

w = 16

Width = 16 inches

Length = w + 3 = 16 + 3 = 19 inches.

Sugar will i need to make enough cookies to feed my whole class is 11 cups.

Given:

A recipe for cookies says 2/3 of a cup of sugar will be enough to feed 3/4 of my class.

2/3 cup of sugar = 3/4 of my class

Multiply by 12 on both sides

2*12/3 = 3*12/4

24/3 = 36/4

8 cups of sugar = 9 of my class.

if 3/4 = 9 whole class = 12.a

Add plus 3 on both sides

8 + 3 = 9 + 3

y = 2x we need to solve when x= -3. Using elimination, we can solve this system of equations like this:

y = 2x

x = -3

Answer:

x=50 y=140

Step-by-step explanation:

Since l and m are parallel, all you have to do is add 40 and y.

Because a straight line has a 180-degree angle, you can subtract 40 from 180 you can find y.

180-40=140

Now we know that 3x-10=140 so we just have to solve.

First, add 10 to each side

3x=150

Then divide by 3

x=50

Eight people skiing downhill in a race can finish in 40,320 different orders.

Calculating probabilities for a set of possibilities keeping in account the order they are in is called permutation ([tex]{n}_P_{r}[/tex]).

According to the question,

We have the following information:

The density of copper is 9.86 g/[tex]cm^{3}[/tex].

Measurements of the solid copper cuboid = 10 cm, 3 cm and 5 cm

We know that the following formula is used to find the volume of cuboid:

Volume = 10*3*5

Volume = 150 [tex]cm^{3}[/tex]

Now, we know that the following formula is used to find the density of an object:

Answer: 26%

Step-by-step explanation: 50 x 0.14 = 7. 12 + 8 + 10 + 7 = 37, 37÷50=0.26 so 26%

The percentage of blue skittles is 26%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Total number of skittles = 50

Red skittles = 12

Yellow skittles = 8

Green skittles = 10

Orange skittles = 14%

This means,

= 14/100 x 50

=  7

Blue skittles.

= 50 - (12 + 8 + 10 + 7)

= 50 - 37

= 13

Yes, quadrilateral ABCD is a parallelogram.

What are the properties of parallelogram?

A parallelogram is a particular sort of polygon. It is a quadrilateral in which the opposite side pairs are parallel to one another.

Properties:

1. Opposite sides are congruent.

2. Opposite angels are congruent.

3. Consecutive angles are supplementary.

4. If one angle is right, then all angles are right.

5. The diagonals of a parallelogram bisect each other.

6. Each diagonal of a parallelogram separates it into two congruent

It is given that the coordinates of the vertices of quadrilateral ABCD are A (8, -3), B(-2, 1), C (-4,-4), and D(6, -8).

According to distance formula,

If A(a,b) and B(x,y) are two coordinates then

AB = [tex]\sqrt{(x-a)^{2}+(y-b)^{2}}[/tex]

Now, using this distance formula in quadrilateral ABCD

AB = [tex]\sqrt{(-2-8)^{2}+(1+3)^{2}}= \sqrt{(-10)^{2}+(4)^{2}}=\sqrt{100+16}=\sqrt{116}[/tex]

CD = [tex]\sqrt{(6+4)^{2}+(-8+4)^{2}}=\sqrt{10^2+(-4)^2}=\sqrt{100+16}=\sqrt{116}[/tex]

Now, If we have two coordinates A(a,b) and B(x,y) then

Slope of AB = [tex]\frac{y-b}{x-a}[/tex]

Using this formula , finding slope of AB and CD of quadrilateral ABCD we get ,

Slope of AB = [tex]\frac{1+3}{-2-8}=\frac{4}{-10}=\frac{2}{-5}[/tex]

Slope of CD = [tex]\frac{-8+4}{6+4}=\frac{-4}{10}=\frac{-2}{5}[/tex]

As slope of both AB and CD is equal therefore, we can say that AB and CD are parallel.

As AB = CD and AB is parallel to Cd Therefore, ABCD is a parallelogram as opposite sides of parallelogram are equal and parallel.

Hence, quadrilateral ABCD is a parallelogram.

A percentage is a figure or a ratio that is expressed as a fraction of 100. The percentage sign, "%," is used to denote it. The percentage is denoted by the abbreviations "pct" or "pc." In other words, the percentage is measured in terms of 100 and is defined as the proportion of one quantity that is made up of another.

The % has no boundaries. It implies that they are dimensionless numbers. When we state a number is 60% of something, we are implying that it is 60% of everything. Even fractional versions, like 0.56% or 0.87%, can be used to express it. Students' exam scores in any subject are calculated as a percentage. For instance, Pooja received a 78% on his exam.

Tax slab is as follows:-

0 - 10,000                  =   3%

10,001 - 50,000         =    5%

50,001 - 100,000       =   5.5%

So total salary = $60000

Till $10000 tax deduction will be 3%

So, $10000 * 0.03 = $300

Then from $10,001 - $50,000 tax deduction will be 5%

Hence, the tax deduction will be $40000 * 0.05 = $2000

And from $50,001 - $100,000 tax deduction will be 5.5%

Only $10000 will be available for tax deduction

so, $10000 * 0.055 = 550
