Bella buys 4 packets of sandwiches at a bottle of water for £1.20 and 3 packets of crisps. Bella pays with a £20 note. She gets £5.75 change. Each packet of crisps has the same price. Work out the price of each packet of crisps.​

Answer:

Answer: 50

"deci" means tenth, so "decimeter" means "tenth of a meter"

0.10 meter = 1 decimeter

1 meter = 10 decimeters (multiply both sides by 10)

5 meters = 50 decimeters (multiply both sides by 5)

Answer:

Step-by-step explanation:

Order of operations:

a)parenthesis

 b) exponents

 c) multiplication or/and division from left to right

 d) addition and/ or subtraction from left to right

The most inside parenthesis  are (-4) , (-10), (-5) and those are just negative numbers that we need to combine with others:

4x negative 4 = -16;  2 - negative 10 = 2+10 = 12; and 9 +negative 5 = 9-5 = 4

( 4 x (- 4 )) / ( 2- (-10) +9 +(-5)) =

( 4 x -4 ) / ( 2+10 +9 -5) =

-16 / (12+4) =

-16 / 16 =

Answer:

(x-9)^2 + (y-9)^2 = 81

Step-by-step explanation:

Step-by-step explanation:Equation of a circle

( x - h )^2 + ( y - k )^2 = r^2

Your graph - the circle intersects the x-axis at (9 , -9)

- the circle intersects the y-axis at (9 , -9)

h = the number on the x axis intersected by the circle.

k = the number on the y axis intersected by the circle.

r = radius of the circle measured starting from the origin.

plug these in:

( x - h )^2 + ( y - k )^2 = r^2.

(x - 9)^2 + (y - 9)^2 = 9^2

(x-9)^2 + (y-9)^2 = 81

We are given with a circle and we need to find the equation of the circle , but first let's recall that , the equation of a circle with radius 'r' and centre at (h,k) is given by [tex]{\bf{(x-h)^{2}+(y-k)^{2}=r^{2}}}[/tex]

Now , here as as the circle cuts the +ve x-axis at (9,0) . So , it's radius is 9 units or the 2nd way is to measure the distance from centre of the circle to the point where the circle cuts the graph , as the centre is at Origin , so here (h,k) = (0,0) .Which means that the centre is located at the point whose coordinates are (0,0) which is also known as origin . Now , finding the equation of the circle :-

[tex]{:\implies \quad \sf (x-0)^{2}+(y-0)^{2}=(9)^{2}}[/tex]

[tex]{:\implies \quad \bf \therefore \quad \underline{\underline{x^{2}+y^{2}=81}}}[/tex]

This is the required equation of Circle

The sum of the considered expression is evaluated to be [tex]\dfrac{x+6}{x+3}[/tex]

Finding the least common multiples of the denominator expressions can help. Then using the similar method as we use in sum of fractions would give the sum of algebraic fractions.

For example,

[tex]\dfrac{a}b} + \dfrac{c}{d} = \dfrac{a \times d + c \times b}{bd}[/tex]

For the considered case, the sum of the given expression is easy to evaluate as the denominators are all same, so their sum will directly apply to their numerators.

The sum is evaluated as follows:

[tex]\dfrac{x}{x+3} + \dfrac{2}{x+3} + \dfrac{2}{x+3} = \dfrac{x + 2 + 3}{x+3} = \dfrac{x + 6}{x+3}[/tex]

Thus, the sum of the considered expression is evaluated to be [tex]\dfrac{x+6}{x+3}[/tex]

Step-by-step explanation:

[tex] \frac{5gb}{110} = \frac{2.3gb}{x} [/tex]

→ x = 2.3 ×110÷5 = 50.6 $ Aaron pay

→Brian = 1.1 × 110 ÷5=24.2$

Caleb = 110 - ( 24.2 + 50.6 ) = 110 -74.8 = 35.2$

Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.

To split the bill among the three brothers in proportion to the data they used, we need to calculate the fraction of the total data used by each brother and allocate the bill accordingly.

The total data used by the three brothers is 2.3gb + 1.1gb + 1.6gb = 5gb.

Now, let's calculate the fraction of the bill that each brother should pay based on their data usage:

Aaron's fraction = 2.3gb / 5gb = 0.46

Brian's fraction = 1.1gb / 5gb = 0.22

Caleb's fraction = 1.6gb / 5gb = 0.32

The sum of these fractions should equal 1, representing the entire bill.

To allocate the bill, we multiply each brother's fraction by the total bill amount:

Aaron's payment = 0.46 * $110 = $50.60

Brian's payment = 0.22 * $110 = $24.20

Caleb's payment = 0.32 * $110 = $35.20

Therefore, Aaron should pay $50.60, Brian should pay $24.20, and Caleb should pay $35.20 to split the bill in proportion to the data they used.

Answer: 215π

Step-by-step explanation:

If you think of the entire thing as two circles, it makes the problem a lot easier. If we were to find the area of the white "circle" and subtract it from the blue "circle", we would get the area of the ring. First, use the outer radius to find the area of this circle:

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

[tex]Area=\pi (24)^2=576\pi[/tex]

Now find the area of the inner circle:

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

[tex]Area=\pi (19)^2=361\pi[/tex]

Subtract the area of the inner circle from the area of the outer circle:

[tex]576\pi -361\pi =215\pi[/tex]

Answer:

Step-by-step explanation:

To factor this, we can factor both variables and then get a multiplier outside the parentheses and the new variables inside. (Sorry if it’s confusing)

18h = 2*3*3*h

30k = 2*3*5*k

Both have 2*3, which is 6. This will be the multiplier. To get the new variables, divide the old variables by 6.

18h/6 = 3h

30k/6 = 5k

The signs should not change.

Your answer would be Slope m = -3

Step-by-step explanation:

Step 1: Graph the points on a coordinate plane( refer to image!)

Whenever your trying to find a slope of 2 order pairs, remember this

m = rise/run. ( Slope = rise over run.) = Δy/Δx

Now we solve:

M = rise/run = Δy/Δx

M = y2 - y1/x2-x1

M = 5 - (-4) / -5-(-2)

So we get  M = 9/-3 and 9 divided by -3 is -3

So, the slope of (-2,-4) and (-5,5) is -3.

Answer:

Step-by-step explanation:

Think of the polygon as being the rectangle GPST added to the triangle PES.

total area = area of rectangle GPST + area of triangle PSE

= 35 + 7

= 42

Just a note of the height of the triangle. The height of triangle PSE, h, is the segment with endpoints E and point (2, 2), so its length is 2.
