Chris wants to create a rectangular rose garden in a yard. He has 48 meters of garden fencing to go around the garden and he has to use it all. Pick two different ways in which he could construct the garden.

Answers

Answer:

If the length is kept 16 or 14  and the breadth 8 or 10 the outer fencing can be 48 meters.

Step-by-step explanation:

The boundary gives the perimeter . Using the formula of the perimeter for a rectangle  where L= length and B= breadth

P = 2(L+B)

48= 2(L+B)

24= (L+B)

The length must be longer than the breadth in the rectangle so we can obtain the sum of 24 in such a way that one side is longer than the other.

24= 16+8

or 24= 14+10

where the length can be 16 or 14 and breadth can be 8 or 10 .

If the length is kept 16 or 14  and the breadth 8 or 10 the outer fencing can be 48 meters.

The answer choice that has the statement that is true about the number line can be seen in the first option.

What is a number line?

A number line is a pictorial representation of lines on a calibrated straight line that serves as a basis for expressing real numbers on a straight line.

We should equally note that:

The left-hand side is the negative x-axis and,The right-hand side is the positive x-axis.

From the given figures;

Point A lies to the negative axis direction on point scale 4 i.e -4Point D lies extremely to another point scale so we can say it is [tex]\mathbf{1 \dfrac{3}{4}}[/tex]Since 3/4 is roughly 0.75 = 1 + 0.75 = 1.75

Therefore, we can conclude that Point A represents -4, Point D represents  [tex]\mathbf{1 \dfrac{3}{4}}[/tex] and  [tex]\mathbf{1 \dfrac{3}{4}}[/tex] > -4.

Answers

Answer:

c = 18

d = 36

Step-by-step explanation:

2c = d (equation 1)

c + d = 54 (equation 2)

Use substitution by putting 2c in the place of d on the second equation.

c + 2c = 54

3c = 54

Then divide both sides by 3 to get c (18).

Then use equation 1 to find d. Do this by putting 18 in the place of c.

2(18) = d

Solve, and the answer is d = 36

Step-by-step explanation:

For a polynomial to be in standard form, it must satify the conditions below:

1) It must not contain like terms

2) The exponents (powers) must be written in descending order

That is, the polynomial must be of the form

[tex]f(x) = {ax}^{n} + {bx}^{n - 1} + {cx}^{n - 2} + . \: . \: . \: . \: . \: mx + n[/tex]

Where a, b, c, m, n, are coefficients/constants

Answers

Answer:

New distance = 2do

Step-by-step explanation:

The distance equation :

Distance = speed * time

If speed is doubled ; time stays the same

If speed is doubled,; new speed becomes

Doubled speed = 2* speed

Time remains the same ;

Hence,

New distance becomes : 2 * speed * time

Original dista, Speed * distance

New distance, dn = 2*do = 2do

I believe you would do 10/3x+1=22/7x-1 and cross multiply meaning multiply 10 by 7x-1 and 22 by 3x+1 and since you can’t really do this you need to make them into an equation. 10(7x-1)=22(3x+1) and distribute leaving you with 70x-10=66x+22 so you minus 66 from both sides leaving you with 4x-10=22 so you add 10 on both sides making it 4x=32 so you divide both sides by 4 leaving you with the answer X=8.

Four rays meet at a common endpoint. Find the value of x. Find the measurement of angle CAD, if angle BAC =60, DAE= 90 and angle BAE= 12x, CAD=3x

Answers

Answer:

x = 14

<CAD = 42degrees

Step-by-step explanation:

Since all the rays meet at a point, the sum of all the angles at the point will be 360 degrees, since angle at a point is 360degrees

Taking the sum of all the angles and equating to 360, we will have;

<BAC + <DAE + <BAE + <CAD = 360

60+90+12x+3x = 360

150 + 15x = 360

15x = 360 - 150

15x = 210

x = 210//15

x = 14

Get <CAD

Since <CAD = 3x

<CAD = 3(14)

<CAD = 42 degrees

Hence the measure of angle CAD is 42degrees

c. Calculate the speed of the car.

Answers

Answer:

a=2

b=40m

Step-by-step explanation:

slope is rise over run so 10/5 simplified is 2/1 or 2

for b just look at the graph at the 20th second

for c you do distance over time so basically the same thing as a 10/5 which is 2m/s
