1 answer:
sp2606 [1]3 years ago

Answer:

a) F

b) B, E, D

Step-by-step explanation:

a) The segment with the greatest gradient has the largest change in y-values per unit change in x-values

From the given option, the rate of change of the <em>y </em>to the<em> </em>x-values of B = the gradient = (4 units)/(2 units) = 2

The gradient of F = (-3units)/(1 unit) = -3

The gradient of A = 4/4 = 1

The gradient of C = -2/5

The gradient of D = 2/6 = 1/3

The gradient of E = 3/4

The segment with the greatest gradient is F

b) The steepest segment has the higher gradient

From their calculated we have;

The gradient of segment B = 2 therefore, B is steeper than E that has a gradient of 3/4, and E is steeper than D, as the gradient of D = 1/3

Therefore, we have;

B, E, D.

How is 6.3 written in scientific notation? 6.3 times. 100 63 times. 10–1 6.3 times. 101 63 times. 100
DanielleElmas [232]

The scientific notation of 6.3 is written as 6.3 × 10^0; option A

<h3>Scientific notation</h3>

  • The decimal points should be moved between the first digit and the next digit.

  • When moving decimal point to the left in scientific notation; it is negative, that is, -

  • When moving decimal point to the right in scientific notation; it is positive, that is, +

Therefore, since there are only two significant number in 6.3, the decimal point can not be moved.

6.3 in scientific notation

= 6.3 × 10^0

In triangle MNP if the measure of angle R is five more than twice x, and the measure of angle S is one more than x, and the meas
Dmitrij [34]

Answer:

x = 19

Step-by-step explanation:

Let's convert the given statements into algebraic expressions.

R is five more than twice x:

R = 2x + 5

S is one more than x:

S = x + 1

T is sixteen less than seven times x:

T = 7x - 16

Also, we know, the sum of 3 angles in a triangle is ALWAYS EQUAL to 180 degrees. Thus we can write:

R + S + T = 180

Substituting the expressions, we have:

2x + 5 + x + 1 + 7x - 16 = 180

Now we do algebra and simply solve for x. Shown below:

2x + 5 + x + 1 + 7x - 16 = 180\\10x-10=180\\10x=180+10\\10x=190\\x=\frac{190}{10}\\x=19

Hence, x = 19

Answer:

Step-by-step explanation:

let it's breadth be x

area of rectabgle=l*b

259=18.5*b

259/18.5=b

14=b

perimeter of rectangle=2(l+b)

=2(18.5+14)

=2*32.5

=65 cm
