A = 2.07 x 10⁶

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number be represented as A

Now , the value of A is

A = 2,070,000

Now , to write the number in scientific notation ,

Multiply the number 207 with powers of 10

So , the value of A will be

A = 207 x 10⁴

Now , the number 207 can be written as 2.07 x 10²

On simplifying the equation , we get

A = 2.07 x 10² x 10⁴

A = 2.07 x 10²⁺⁴

A = 2.07 x 10⁶

Therefore , the value of A is 2.07 x 10⁶

Hence , the value of the number is 2.07 x 10⁶

Answer:

15c + 25s ≤ 1500

Step-by-step explanation:

Let the number of stools be s

Let the number of chairs bought be c

If each tools cost $15, s stools will cost $15c

If a chairs cost $25, c chairs will cost $25s

Total costs = 15c + 25s

If the center cannot spend more than $1500, then the required equation will be 15c + 25s ≤ 1500

The inequality sign will be less than and equal to since they cannot spend an amount greater than $1500.

Hence the correct equation is  15c + 25s ≤ 1500

ΔBCE is half the base length and two third the height of ΔACF, therefore,

the area of ΔBCE is less than half the area of ΔACF.

The area of triangle ΔBCE is 60 cm².

Reasons:

In ΔACF, we have;

B = The midpoint of AC

Point E and point D are points on side CF

Distance C to D = Distance D to E = Distance E to F

Area of ΔACT = 180 cm²

Required:

Area of ΔBCE

Solution:

[tex]Area \ of \, \Delta ACF = \mathbf{\dfrac{1}{2} \times AC \times CF} = 180 \ cm^2[/tex]

[tex]In \ \Delta BCE, \, BC = \dfrac{1}{2} \times AC \ and \ CE = \dfrac{2}{3} \times CF[/tex]

Therefore;

[tex]Area \ of \ \Delta BCE = \dfrac{1}{2} \times BC \times CE = \dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF[/tex]

[tex]\dfrac{1}{2} \times \left(\dfrac{1}{2} \times AC \ \right) \times \dfrac{2}{3} \times CF = \dfrac{1}{2} \times \dfrac{2}{3} \times \left(\dfrac{1}{2} \times AC \ \right)\times CF = \mathbf{\dfrac{1}{3} \times Area \ \Delta ACF}[/tex]

Therefore;

[tex]Area \ of \ \Delta BCE = \dfrac{1}{3} \times Area \ \Delta ACF = \dfrac{1}{3} \times 180 = 60[/tex]

The area of triangle ΔBCE = 60 cm².

Step-by-step explanation:

Answer:

20%

Step-by-step explanation:

We can start by looking at it as a ratio, so 4 divided by 20 and 4/20 = 0.2, so that would be 20% viewing 1=100%.

Another way is

20 here is 100%, and for 20 to equal 100, we have to multiply it by 5. To balance it out, multiply the top by 5 as well, and 4 * 5 =20. Therefore, 4/20 = 20%

307 divided by 7 is the number of students in each bus with the remainder 6. As the 6 students cannot be fit into the bus and had to travel by car.

Thus we can conclude that:

307= 7x + 6 (6 extra students)

Take away 6 on both sides

Answer:

x = 20

Step-by-step explanation:

The length of the segment EG can be obtained as the sum of the segments EF and FG, that is:

EG = EF + FG

We are given:

EF = 4x + 14

FG = 50

EG = 144

Thus, we set the equation:

144 = 4x + 14 + 50

Simplifying:

144 = 4x + 64

Subtracting 64:

80 = 4x

Dividing by 4:

x = 80/4 = 20

x = 20

Answer:

$3.53

Step-by-step explanation:

hot dogs = $1.25 each

2 hot dogs = 1.25 × 2

= $2.50

A serving of onion rings = $2.99

Drink = $0.98

Total amount with Karen = $10.00

how much change will Karen receive?

Total cost = 2 hot dogs + A serving of onion rings + Drink

= $2.50 + $2.99 + $0.98

= $6.47

Karen's change = Total amount with Karen - Total cost

= $10.00 - $6.47

= $3.53

Answer:

yes it's on a 1.5 scale factor.....I think. The question you put at the top threw me off at first but the picture makes sense. I'm not entirely sure if this is right but if you adjust the triangle to be the same way as the other one then you will see which sides correspond to each other. Each number can be multiplied by 1.5 to get the number that is on the side of the other triangle that corresponds with it....if that makes any sense
