21. Here are the ingredients for raspberry ripple ice cream.
250g raspberries
225g caster sugar
2 large eggs
4 large egg yolks
600ml double cream
A mother has 5 litres of cream to make ice cream for a party. Sugar comes in 1kg bags.
How many bags of sugar will be needed?
Answer:
10 bags for 5 litres of cream of ice cream.
2 bags of sugar will be needed.
What are comparing quantities?Comparing quantities is the qualitative relation between two quantities which reflects the relative size of both the quantities.
here, we have,
It is given that,
600ml of cream requires = 225g of sugar
⇒ 1 ml of cream requires = 225/600g of sugar
⇒ 5000ml of cream requires = 225/600 * 5000g of sugar
= 1875g
=1.875 kg
Hence we see that , Sugar comes in 1kg bags.
Similarly, 1.875kg of sugar = 1kg bag + 0.875kg bag
⇒ 2 bags of sugar is needed.
Therefore, 2 bags of sugar will be needed.

Solve for x
TS = 2x - 6
CE = 3x - 6
Use midpoint theorem :- The line segment in a triangle joining the midpoint of two sides of the triangle is said to be parallel to its third side and is also 'half of the length of the third side'.
So,
2x - 6 = ½ (3x - 6)
2x - 6 = 3x/2 - 3
2x - 3x/2 = -3 + 6
½ x = 3
x = 3 × 2
x = 6

HELP PLEASE!!!!! THIS IS DUE TODAY!!!!
Answer:
nonlinear
Step-by-step explanation:
it's a parabola
please solve quickly
Step-by-step explanation:
aVolume = length ×width × height
therefore
5cm× 6cm×2cm=volume
60cm³= volume
the volume is 60cm³bVolume = length ×width × height
1200mm³=20mm×10mm×H
1200mm³=200mm²×H
1200mm³/200mm²=200mm²/200mm²×H
6mm= H
the height is 6mm cVolume = length ×width × height
72m³=L×3m ×6m
72m³= L× 18m²
72m³/18m²= L×18m²/18m²
4m =L
the length is 4mdVolume = length ×width × height
256cm³=8cm ×w×8cm
256cm³=64cm²×w
256cm³/64cm²=64cm²/64cm²×w
4cm=w
the width is 4cm eVolume = length ×width × Height
379.6m³=5.2m×7.3m×H
379.6m³=37.96m²×H
379.6m³/37.96m²=37.96m²/37.96×H
10m=H
the height is 10mfVolume = length ×width × Height
288mm³=L×12mm×8mm
288mm³= L×96mm²
288mm³/96mm²= L×96mm²/96mm²
3mm=L

Step-by-step explanation:
Split the trapezoid into parts, a rectangle and a triangle. The dimensions of the rectangle will be 3 and 8, so 3*8=24. 24 is part of the answer. The dimensions of the triangle are 4 and 3, and 4*3/2 is 6, so 6 is the other part of the answer. 24 + 6 = 30.

Part G Compare this activity tracker & with the calorie calculator you used in part A. Imagine that a company hires you to make an online tool that uses the best features of each calculator to give users an accurate sense of their physical activity and energy expenditure. What features would you use from each calculator? How would your calculator work?
Answer:
The physical activity calculator helps calculate minutes of activity and breaks down the types of activities performed every week. The calorie calculator doesn’t keep track of all activities. However, it calculates calorie expenditure. A new calculator might be a combination of the two calculators. It’d be a two-step process. People would be able to enter their age, gender, weight, height, and any medical factors so that they can ensure that their calorie calculations are accurate. Then, they’d be able to track the calories expended each day for a week by adding their activities for the whole day, from sitting to exercising. This information would give them an accurate portrayal of calorie expenditure and estimated caloric requirement.

what is an equation in slope-intercept form for the line (-5, 2) and (5,-3)?
Answer:
y = [tex]-\frac{1}{2} x[/tex] [tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
solved using point-slope form
points given: (-5, 2) and (5, -3)
slope: [tex]\frac{-3-2}{5-(-5)} =\frac{-5}{10} =-\frac{1}{2}[/tex]
y = [tex]-\frac{1}{2}[/tex] x + b
insert x- and y- values of (-5, 2) and solve for b
2 = [tex]-\frac{1}{2}[/tex] (-5) + b
2 = 2.5 + b
subtract 2.5 from both sides
2 - 2.5 = 2.5 + b - 2.5
-0.5 = b
insert b- value
y = [tex]-\frac{1}{2} x[/tex] [tex]-\frac{1}{2}[/tex]
Given that a [] b = b2 + a. Evaluate 2 [] (6[] - 5).
Answer:
963
Step-by-step explanation:
Evaluate 6 | - 5 , then the outside part, that is
6 | - 5 ( with a = 6 and b = - 5 )
= (- 5)² + 6 = 25 + 6 = 31
Now evaluate 2 | 31 ( with a = 2 and b = 31 )
= 31² + 2 = 961 + 2 = 963
are these lines perpendicular explain
Answer:
Yes because the slopes are negative reciprocals of each other.
Step-by-step explanation:
The slope of line B is: 1/3
(-2, -4) and (1, -3)
(-3+4)/(1+2) = 1/3
The slope of line A is: 3
(-3, 0) and (-2, -3)
(-3-0)/(-2+3) = -3
