Answer:

get the inequality first ! x<44

Step-by-step explanation:

3/4x+8<41 ( subtract 8 from both sides. 8 cancels out. and 41-8=33 )

3/4x<33 ( multiply both sides by 4/3)

3/4 ×4/3 = 1

33×33 =44

x<44

and to graph it your line should have a open circle on 44 and point to the left.

Answer:

3 boxes of fertilisers.

Solving steps:

Part A:

Area of the garden, rectangle:

Length * Width

12 * 7

84 m²

Area of patio:

[tex]\sf{\frac{1}{2} * base *height[/tex]

[tex]\sf{\frac{1}{2} * 6*3[/tex]

[tex]\sf{9[/tex] m²

Area of grass:

Area of the garden - Area of patio

84 m² - 9 m²

75 m²

Part B:

32 m² ↔  1 box

1 m²    ↔ [tex]\sf{ \frac{1}{32}[/tex] box

75 m²  ↔ [tex]\sf{ \frac{1}{32} *75[/tex] boxes

75 m²  ↔ 2.34375 boxes

She should buy 3 boxes of fertilisers.

Answer:

3

Step-by-step explanation:

First, calculate the total area of the grass by calculating the area of the rectangle and the triangle, and then subtracting the triangle area from the rectangular area:

area of rectangle = width x length

⇒ area of rectangle = 7 x 12 = 84 m²

area of triangle = 1/2 x base x height

⇒ area of triangle = 1/2 x 6 x 3 = 9 m²

total area of the grass = area of the rectangle - area of triangle

⇒ total area of the grass = 84 - 9 = 75 m²

Given one box of fertilizer = 32 m² grass

⇒ boxes of fertilizer needed = area of grass ÷ 32

                                                = 75 ÷ 32

                                                = 2.34375

Therefore, Mrs Kunal will need 3 boxes of fertilizer.  

We need to round up to 3 rather than round down to 2, else she won't have enough to cover the entirey of the grassed area.

Answer:

yes

Step-by-step explanation:

Let's call the first integer n and let's compute.[tex]n^2 + (n+1)^2 + (n+2)^2 +(n+3)^2 = \\n^2 + \\n^2+2n+1 + \\\ n^2+4n+4 + \\\ n^2+6n+9+\\\ n^2+8n+16 =\\4n^2+20n +30 = 2 (2n^2+10n+15)[/tex]

Which is indeed of the form 2(something), so it is even.

Answer:

50.24 cm

Step-by-step explanation:

A = pi r^2

A = 3.14 (4^2)

A = 3.14 (16)

A = 50.24 cm

Answer:

[tex]A=50.24cm^2[/tex]

Step-by-step explanation:

[tex]A=\pi r^2[/tex]

d = 8

r = d/2   r = 8/2 = 4

[tex]A=\pi (4^2)[/tex]

[tex]A=\pi 16[/tex]

[tex]A=3.14(16)[/tex]

[tex]A=50.24cm^2[/tex]

Answer:

122ft

Step-by-step explanation:

(Note that this is just a logical guess, I do not remember learning how to do this)

We are given the length of the pole and the length of the guy wire after the pole. This gives us a right angle triangle where we know two of the sides. We can the other two sides into the Pythagorean theorem to solve for the diagonal side

recall:

[tex]{a}^{2} + {b}^{2} = {c}^{2} [/tex]

plugged in 12ft and 2ft we get:

[tex] {(12)}^{2} + {(2)}^{2} = 148[/tex]

to solve for the diagonal side we take the square root of 148

[tex] \sqrt{148} = 12.17[/tex]

so now we know that 12.17 ft of wire is equivalent to 2 feet on the ground.

[tex] \frac{12.17ft \: wire}{2 \: ft \: ground} [/tex]

We have a total of 20 feet, so we multiply this proportion by 20:

[tex] \frac{12.17}{2} \times 20 = 121.7[/tex]

we are asked to give to the nearest foot so we round up to 122ft

Step-by-step explanation:

Our problem:

[tex] \frac{2}{3} \div \frac{4}{5} = unknown[/tex]

How to solve?

Find the reciprocal (opposite) of 4/5, then multiply. Simplify if necessary.

Find the reciprocal:

[tex] \frac{2}{3} \times \frac{5}{4} = unknown[/tex]

Multiply:

[tex] \frac{2}{3} \times \frac{5}{4} = \frac{10}{12} [/tex]

Simplify:

[tex] \frac{10 \div 2}{12 \div 2} = \frac{5}{6} [/tex]

5/6 is your answer.

Answer:

angle(2) = 118 degree

angle(3) = 118 degree

angle(4) = 62 degree

Step-by-step explanation:

To find angle 2 :

[tex]62 + angle{2} = 180 \\ angle{2} = 180 - 62 = 118 \: degree[/tex]

The rule (head to head):

angle(2) = angle(3) = 118 degree

And the last one is angle(4) which is the same thing:

angle(4) = angle(1) = 62 degree

Answer:

yes

Step-by-step explanation:

For the lengths to be the sides of a triangle.

The sum of any 2 must be greater than the third.

8 + 11 = 19 > 14

8 + 14 = 22 > 11

11 + 14 = 25 > 8

Then the 3 lengths can form the sides of a triangle

Answer:

Yes, it can be the sides of a scalene triangle.

Step-by-step explanation:

Because the sides and the angles of a scalene triangle are different.

Answer:

C) [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

Slope can be found using the change in y over the change in x

-> See attached, it is difficult to type out here

[tex]\frac{-5--2}{3--1} =\frac{-5+2}{3+1} =\frac{-3}{4}[/tex]

Giving us an answer of C) [tex]\frac{-3}{4}[/tex]

Answer:

[tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

The equation for slope is:

[tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]

We can plug the given coordinates into the equation:

[tex]Slope=\frac{-5-(-2)}{3-(-1)}=\frac{-5+2}{3+1}=\frac{-3}{4}=-\frac{3}{4}[/tex]

Answer:

5

Step-by-step explanation:

I se you labeled the points, the distance between them can be found by adding the distances from 0:

5/2 + 5/2

Since they have the same denominator we can just add the numerators:

5 + 5 = 10

So 10/2, which can be simplified into 5 since 10 goes into 2, 5 times.

Hope this helps!! :)

Answer:

x = 81

Step-by-step explanation:

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex]

given

[tex]log_{3}[/tex] x = 4 , then

x = [tex]3^{4}[/tex] = 81

Answer:225 tiles

Step-by-step explanation:

area of floor=number of  tile * area of each tile

side*side= x *(side*side)

300*300=x * (20*20)

300/20*300/20=x

15*15=x

225=x

Step-by-step explanation:

1.

the y-intercept comes automatically from the given form, as the y-intercept is the y value when x = 0.

so, in

x² - 12x + 46

the y-intercept is 46, or as point (0, 46).

now to the vertex form and vertex itself.

the vertex form for such a quadratic equation is

y = a(x - h)² + k

with (h, k) being the vertex.

since we have a plain x² term in the basic expression, "a" must be 1.

so, we have the simpler version

y = (x - h)² + k = x² - 2hx + h² + k

so, let's compare this with our basic expression, and we see

-2h = -12

h = 6

h² + k = 46

6² + k = 46

36 + k = 46

k = 10

so, the vertex form is

y = (x - 6)² + 10

and the vertex is (6, 10)

2.

the equating of a circle is

(x - x1)² + (y - y1)² = r²

with (x1, y1) being the center of the circle, and r being the radius.

so, the center is then (3, -3), and the radius is sqrt(36)=6.

3.

as explained in 2. this would be

(x - 4)² + (y + 9)² = 3² = 9

4.

x² + y² + 6x - 2y + 9 = 0

this has to turn into

(x - x1)² + (y - y1)² = r²

x² - 2x×x1 + x1² + y² - 2y×y1 + y1² = r²

x² - 2x×x1 + x1² + y² - 2y×y1 + y1² - r² = 0

"x² + 6x" suggests that for x1 of the first term

6x = - 2x×x1

x1 = -3

and "y² - 2y" suggests for y1 of the second term

-2y = -2y×y1

y1 = 1

that gives us for the constant terms and radius

x1² + y1² - r² = 9

(-3)² + 1² - r² = 9

9 + 1 - r² = 9

1 - r² = 0

r² = 1

r = 1

so, the standard circle equation is

(x + 3)² + (y - 1)² = 1

1. Eight more than a number 14 -> 14 + 8 = 22
2. Number decreased by 12 is 9 -> 9 + 12 = 21
3. 20 subtracted from walters age is 24 -> 24 + 20 = 44
4. Ten more than twice as jose's age is 24 -> (24-10)/2 = 7
5. x + 15 = 2x -> x = 15

Answer:

The way that I memorised how to do sin, cos, and tan is by the following: SOH, CAH, TOA

SOH = Sin is OPPOSITE / HYPOTENUSE

CAH = Cos is ADJACENT / HYPOTENUSE

TOA = Tan is OPPOSITE / ADJACENT

For example if we were to solve question 5

Sin T = 6 root 2 / 19

Cos T = 17 / 19

Tan T = 6 root 2 / 17

Repeat the steps for question 6

For the rest of the questions (7,8,9) you have to take the information given and figure out if you should us Sin, cos, or Tan. then plug the numbers in the calculator and while doing sin ^ -1, cos ^ -1, tan ^ -1

for example on question 7, to find the angle x they have given you the hypotenuse and the adjacent side so

cos x = 9 / 18

to find x plug: cos^-1 (9/18) in the calculator

the equation is y = 8x

Step-by-step explanation:

so rn we know that the y-intercept 0 so we can write:

y = mx

now to find the slope we need to use the equation y2 - y1/ x2 - x1

lets use the points
