Factorise the following expressions :​

Answer:

let's divide the figure in rectangle and triangle.

first we should find the area of triangle.

area of triangle =1/2×base×height

area of triangle=1/2×11cm×7cm

area of triangle=38.5cm²

area of rectangle =length ×width

area of rectangle =11cm×8cm

area of rectangle =88cm²

area of the figure=38.5cm²+88cm²

area of the figure=126.5cm²

Answer:

A 1/3

Step-by-step explanation:

Answer:

7.5 or 15/2

Step-by-step explanation:

x-3x+6=2x-24 -- Combine like terms

-2x+6=2x-24 -- Add 2x to each side

6 = 4x-24 -- add 24 to each side

30 = 4x -- divide by 4

15/2 or 7.5 = x

Answer:

2^10

When multipying indices, if the base is the same then just add the indices.

Answer: The answer is the first choice that states “ASA”.

Step-by-step explanation: ASA means angle, side, angle. From T - Q in triangle STQ it goes from angle, side, angle. From P - M in triangle NPM it also goes from angle, side, angle.

Answer:

[tex]\frac{9}{24}[/tex]

Step-by-step explanation:

Add all the sweets together ( that will be your denominator )

5+4+8+4+3= 24

The probability she will pick and yellow and orange ( add those numbers together)

Yellow + orange = Numerator

5+4=9

How you answer should be lay out :

[tex]\frac{Orange+ yellow sweets}{Total amount of sweets}[/tex]

Answer:

9/24

Step-by-step explanation:

add the sweets (for denominator) 5+4+8+4+3 =24 then add yellow +  orange (which is 9)

If the bill of the restaurant comes to $46.27 then the tip of 10% is equal to $4.627.

Percentage is number or ratio that is expressed as a fraction of 100. It is shown by % sign. It shows some quantity over other quantity. The number which shows the percentage is the number in the quantity itself.

We have been given that the bill of the restaurant comes to $46.27 and 10% is the tip. We have to calculate the tip.

Tip=Bill*10/100

=46.27*10/100

=4627*10/100*100

=46270/10000

=$4.627

Hence if the bill of the restaurant is $46.27 then tip will be $4.627.

Step-by-step explanation:

Rule AAA defines these two triangles as congruent.

Answer:

x - 5y = 5

Step-by-step explanation:

Let's represent the equation of the graph in slope-intercept form, y = mx + b.

We'd need to find slope (m) and y-intercept (b) of the graph.

Slope (m) = ∆y/∆x

Using two points on the line, (0, -1) and (5, 0),

Slope (m) = (0 - (-1)) / (5 - 0) = 1/5

m = ⅕

y-intercept (b) is the point on the y-axis where the line intercepts the y-axis = -1

Therefore, b = -1

To write the equation, substitute m = ⅕ and b = -1 into y = mx + b

Thus:

y = ⅕(x) + (-1)

y = ⅕(x) - 1

Rewrite in standard form:

-⅕x + y = -1

Multiply both sides by -5

-⅕x*-5 + y*-5 = -1*-5

x - 5y = 5

Answer:

6    23.2    40.4     57.6    74.8      92

Step-by-step explanation:

92-6 = 86

86/5 spaces = 17.2 each

Answer:

1) 5% of 90m= 4.5m

2)25% of 88kg = 22kg

3) 75% of 264= 198

Step-by-step explanation:

1) 90m = 100% (divide by 10)

9 = 10% (divide by 2)

4.5 = 5%

2) 88kg = 100% (keep on dividing by 2)

44kg = 50%

22kg=25%

3) 264 = 100%

132 = 50%

66 = 25% (add)

198=75%

Answer:

f(n)=17+3(n-1)

f(17)=65

Step-by-step explanation:

arithmetic  sequences are in form:

f(n)=f(o)+d(n-1)

f(1)=17=f(0)

f(n)=17+3(n-1)

f(17)=17+3(16)=65

Answer:

x = 9

y = 6

Step-by-step explanation:

ΔABC ~ ΔPQR

Therefore, corresponding sides of these similar triangles will be in the proportional.

[tex]\frac{AB}{PQ}=\frac{BC}{QR}= \frac{AC}{PR}[/tex]

[tex]\frac{6}{x}= \frac{4}{y}= \frac{8}{12}[/tex]

[tex]\frac{6}{x}= \frac{8}{12}[/tex]

x = [tex]\frac{12\times 6}{8}[/tex]

x = 9

Similarly, [tex]\frac{4}{y}= \frac{8}{12}[/tex]

y = [tex]\frac{12\times 4}{8}[/tex]

y = 6

Answer:

A. d = 25; the unit rate is 25 miles per gallon

Step-by-step explanation:

The point (1, d) on the graph represents (x, y), where,

x = gasoline used = 1 gallon

y = distance = d = 25 miles

That is, (1, d) represents when x = 1, y = 25.

Thus, (1, 25) is the unit rate which is 25miles per gallon.

The weight varies directly with the number of boxes, so this means every box weighs the same amount.

Find the weight of a box by dividing the known weight by the number of boxes:

600 pounds / 16 boxes = 37.5 pounds per box.

Now multiply the weight per box by the number of boxes:

37.5 pounds x 12 boxes = 450 pounds

12 boxes weigh 450 pounds
