Step-by-step explanation:

SOH-CAH-TOA

cos35=5/x

x=5/cos35

x=6.1m

Answer:

Rs 64000

Step-by-step explanation:

Since breadth B = 80% of length L, B = 0.8L

Perimeter, P = 2(L + B) = 360m

Substituting B = 0.8L into P, we have

2(0.8L + L) = 360 m

2(1.8L) = 360 m

3.6L = 360 m

L = 360m/3.6

L = 100 m

So, B = 0.8L = 0.8(100 m) = 80 m

The area of the rectangular ground is A = LB = 100 m × 80 m = 8000 m²

So, the cost of planting the ground at Rs 8 per m² is  Rs 8 per m² × 8000 m² = Rs 64000

Step-by-step explanation:

The 1st equation is in slope-intercept form.

=> Slope = 4

The 2nd equation is in point-slope form.

=> Slope = -1/4

Since their slopes are unequal,

The lines are not parallel to each other.

However the product of their slopes is -1,

Therefore the lines are perpendicular to each other.

The answer is the 2nd option.

Answer:

8

Step-by-step explanation:

The Pythagorean theorem shows us that the measure of the sides in a right triangle can be calculated using the formula a^2 + b^2 = c^2. Using this formula, and filling in the blank, we can conclude that the other leg measures 8 cm.

Step-by-step explanation:

Answer:

x=-4

Step-by-step explanation:

9x-17=5x-1 isolate X

9x-17=5x-1 add +1 to each side of the equation 9x-17+1=5x-1+1 the ones cancels out... 9x-16=5x

add -9x to both sides..... 9x-16+9x=5x-9x...... 9x-9x-16=5x-9x

-16=5x-9x subtract 5x-9x

-16= - 4x divide both sides by -4

-4=x or x=-4

Answer:

x = 1 ; y = 3

Step-by-step explanation:

5(2x + 3y = 11)

2(5x + 3y + 14)

(distribute)

10x + 15y = 55

10x + 6y = 28

(subtract)

9y = 27

(divided 9 to both sides)

9 divided by 9 cancels out and 27 divided by 9 = 3

so..

y = 3

now, using any equation, (i’ll be using 2x + 3y =11) plug in the y value to find the x value

2x + 3y = 11

2x + 3(3) = 11

(multiply 3 x 3)

2x + 9 = 11

(subtract 9 from 9 and 11)

2x = 2

(divide 2 from both sides)

2 divided by 2 = 1

therefore...

x = 1

Answer:

[tex]y=-\frac{1}{3} x+5[/tex]

Step-by-step explanation:

This question is asking for slope-intercept form which is y=mx+b, where m is the slope and b is the y-intercept. First, find the slope; this can be done in two ways, counting change in y and x then dividing, or using the formula [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]. Either way for this graph the slope comes out as -1/3. Next, find the y-intercept, this is where the line intersects with the y-axis. In this case, the line touches the axis at 5, therefore 5 is the value of b.

Step-by-step explanation:

Answer:

4. 110 slices

5. B.12.8 mi

Step-by-step explanation:

For question for you divide the number of slices, 176, by the number of loafs, 8. this give give you a total of 22. you then take 22 and multiple if by 5, leaving your answer to 110 slices of bread.

For question 5, you multiple 8 kilometers by 1.6 kilometers, which is 12.8 miles.

Answer:

g = 5

Step-by-step explanation:

6(g-3)=12

6g-18 = 12

6g = 30

g = 5

Answer:

g = 5

Step-by-step explanation:

→ Expand the bracket

6g - 18 = 12

→ Add 18 to both sides to isolate 6g

6g = 30

→ Divide both sides by 6 to isolate g

g = 5

Answer:

X=2.5

Step-by-step explanation:

3x - 5 = 1/2x + 2x

3x - 1/2x - 2x = 5

1/2x = 5

X = 5 ÷ 1/2

X = 2.5

Answer: 3) Not factorable

We cannot use the difference of squares method because we don't have a subtraction going on (ie "difference") and we don't have two perfect squares. The value 70 is not a perfect square.

We cannot factor out a GCF since the GCF here is 1, and that doesn't really affect things. Choice 4 is also not applicable because we don't have a trinomial. A trinomial has three terms.

Answer:

A(t) = 0.825 g

Step-by-step explanation:

To solve this for amount remaining, we will use the equation;

A(t) = A_o × (½)^(t/t_½)

We are given;

Initial amount; A_o = 6.6 g

Half life; t_½ = 14

Time elapsed; t = 42

A(t) is amount of substance remaining

Thus;

A(t) = 6.6 × (1/2)^(42/14)

A(t) = 6.6 × (1/2)³

A(t) = 6.6 × ⅛

A(t) = 0.825 g
