Answer:
£8.4
Step-by-step explanation:
Since she swapped half and now has £4.20, then multiply that by 2
4.20 × 2 = 8.4
Alex initially had £8.4
The initial amount of Alex's 2p coins is £8.40
Let the initial worth of 2p coins = y
Half of y = y/2 The value of y/2 = £4.20The amount of money Alex had initially = yWe can then solve for the worth of y, which is the titla amount Alex had initially ;
y/2 = £4.20Multiply bith sides by 2 (y/2)×2 = £4.20 × 2 y = £8.40Therefore, the amount of money Alex had initially is £8.40

Una parcela de forma cuadradra mide 1089km2 de superficie cuantos metros mide el lado de la parcela
Respuesta:
3.3 × 10⁴ m
Explicación paso a paso:
Paso 1: Información provista
Superficie de la parcela cuadrada (S): 1089 km²
Paso 2: Determinar la longitud del lado (l) de la parcela
Podemos determinar la superficie de un cuadrado usando la siguiente fórmula.
S = l²
l = √S = √1089 km² = 33 km
Paso 3: Convertir "l" a metros
Vamos a usar el factor de conversión 1 km = 10³ m.
33 km × 10³ m/1 km = 3.3 × 10⁴ m

Shamika bought 3 skirts that cost $25 each before the discount. What was her total after thediscount?
A. $45.00
B. $48.75
C. $52.50
D. $56.25
Answer:
The answer is C and please give me brainliet And a like!
Where the above parameters are given, Shamika's total after the discount is $56.25. (Option D)
How to compute the above resultAccording to the table, if the total purchases are less than $50, the discount is 25%.
Shamika bought 3 skirts at $25 each, so her total purchase amount is 3 * $25 = $75.
Since $75 is less than $50, she qualifies for a 25% discount.
To calculate the discount, we multiply the total purchase amount by the discount rate -
Discount = 25% of $75 = (25/100) * $75 = $18.75
To find her total after the discount, we subtract the discount from the total purchase amount -
Total after discount = Total purchase amount - Discount
Total after discount = $75 - $18.75 = $56.25
Therefore, Shamika's total after the discount is $56.25. (Option D)

PLEASE HELP I DONT KNOW HOW TO SOLVE THIS :((
Answer:
[tex]\displaystyle \angle A=30^\circ[/tex]
Step-by-step explanation:
We are given that in Circle O, Arc BAC measures 300°.
Recall that arc lengths will always total 360°. Therefore:
[tex]\stackrel{\frown}{BAC}+\stackrel{\frown}{CB}=360^\circ[/tex]
By substitution:
[tex]300+\stackrel{\frown}{CB}=360[/tex]
Thus:
[tex]\stackrel{\frown}{CB}=60^\circ[/tex]
∠A intercepts Arc CB. Since it is an inscribed angle, it will be half of its intercepted arc. In other words:
[tex]\angle A=\displaystyle \frac{1}{2}\stackrel{\frown}{CB}[/tex]
Therefore:
[tex]\displaystyle \angle A=\frac{1}{2}(60)=30^\circ[/tex]

Shannon scored 36 point on 6 questions on her test. what is the unit rate for one question?
Answer:
6 poinnts per question
Step-by-step explanation:
Answer:
x = the number of points for each question
6 = number of questions
36 = total number of points
number of questions times the number of points will equal total points
6x = 36
divide both sides by 6
6x/6 = 36/6
x= 6

An actor, Bob, wants to gain weight to look the part for his role as an overweight truck driver in an upcoming movie. He decides to add servings of banana splits (S) and bacon rolls (B) to his diet. Each serving of S is 1,000 calories and each serving of B is 500 calories. Bob has a history of health problems and his doctor has recommended that he needs to control his cholesterol and sugar levels in his food intake. Each serving of S contains 1 unit of cholesterol and 3 units of sugar. Each serving of B contains 4 units of cholesterol and 1 units of sugar. His doctor recommends that his cholesterol be no larger than 10 units and his sugar levels should be at least 2 units and no larger than 9 units. What should be the objective function (C) to select the optimal choice of Sand B in order for Bob to ingest as many calories as possible? A. C = 105 + 5B B. C = 1000S + 500B C. C = S+BD. None of the above
Answer:
[tex]C = 1000S + 500B[/tex]
Step-by-step explanation:
Given
[tex]S = Banana\ Splits[/tex]
[tex]B=Bacon\ Rolls[/tex]
Reading through the question, we have:
Number of calories per serving:
[tex]S \to 1000[/tex]
[tex]B \to 500[/tex]
Let
[tex]x = Cholesterol[/tex]
[tex]y =Sugar[/tex]
So, we have:
Each serving of S
[tex]x \to 1S[/tex]
[tex]y \to 3S[/tex]
Each serving of B
[tex]x \to 4B[/tex]
[tex]y \to 1B[/tex]
Recommendation
[tex]x \to \le 10[/tex] - i.e. not more than 10 units of cholesterol
[tex]y \to \ge 2 \& \le 9[/tex] i.e. At least 2units but not more than 9 units of sugar
So, the constraints are:
[tex]S + 4B \le 10[/tex]
[tex]3S + B \ge 2[/tex]
[tex]3S + B \le 9[/tex]
Recall that the calories per serving is:
[tex]S \to 1000[/tex]
[tex]B \to 500[/tex]
Hence, the objective function is:
[tex]C = 1000S + 500B[/tex]
