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

Should you use Sine, Cosine, Tangent to solve the following problem
Answer:
tangent
Step-by-step explanation:
SOH( sin = opposite/hypotenuse)
CAH(cosine = adjacent/hypotenuse)
TOA(tan = opposite/adjacent)
you are trying to find x and the numbers given to you are opposite of x and adjacent to x. that means you need to use toa
We will use Tangent of the angle.
What is Tangent of the angle?In trigonometry, the tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
Given that, a right triangle, with perpendicular = x and an acute angle = 28° and base = 14
Since, we know that, tan α = opposite side / adjacent side
In other two trigonometric ratios, we need the length of hypotenuse, which is not given.
Hence, We will use the Tangent of the angle.

Answer: 85 m + 20
Step-by-step explanation:
Make fractions have same, common denominator. LCD = 40
7/8 = 35/40
9/10 = 36/40
2/5 = 16/40
3/1 = 120 / 40
[tex]\frac{35}{40}m+\frac{36}{40}-\frac{120}{40}m - \frac{16}{40}[/tex]

A class has 12 girls and 18 boys. What is the probability that a boy raises his hand and asks to go to the bathroom given a girl already left the room to go to the bathroom?
Answer:
The answer is [tex]\frac{18}{29}[/tex]
Explanation:-
Total number of students = 12 + 18 = 30
Total number of students after one girl left = 29
Number of boys = 18
Probability that a boy raises his hand and asks to go to the bathroom =
Number of boys divided by total number of students
[tex]\frac{18}{29}[/tex]

Answer:
x ≈ 11.1
Step-by-step explanation:
Using the sine ratio in the right triangle
sin59° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{13}[/tex] ( multiply both sides by 13 )
13 × sin59° = x , then
x ≈ 11.1 ( to the nearest tenth )
Answer:
11.14 to nearest hundredth.
Step-by-step explanation:
sine = opposite side/ hypotenuse so here we have:
sin 59 = x/13
x = 13 sin 59
= 11.143

A water container in the shape of a cone has a height of 5 inches and a diameter of 3.5 inches.
Enter an equation in the first blank box and a number in the second blank box to complete the statements about the
water container ___.
A. The formula to calculate the container's volume, V, with the given measurements is
B. The container can hold approximately ___ cubic inches of water. Round your answer to the nearest hundreth.
Answer
A. The formula to calculate the container's volume, V, with the given measurements is ⅓ π(1.25²)5.
B. The container can hold approximately 8.177 cubic inches of water. Round your answer to the nearest hundredth.
Step-by-Step Explanation
A. The formula to calculate any cone's volume is ⅓ πr²h. Replace the variables with the actual values of the cone. r stands for the cone base's radius, or half of the diameter. Because the diameter is 3.5, the radius is 1.25, or half of it. The h stands for the height of the cone. Now we can plug in the values. Our answer for this part is ⅓ π(1.25²)5.
B. Now to solve our equation. [tex]1.25^2[/tex] is equal to 1.5625. Now, multiply by the height. 1.5625 x 5 is equal to 7.8125. We now multiply by [tex]\pi[/tex]. We'll use 3.14 to shorten the answer a bit. Multiply 7.8125 by 3.14 and you'll get 24.53125. Last but not least, divide this by 3 (or multiply by [tex]\frac{1}{3}[/tex]). [tex]\frac{24.53125}{3}[/tex] = 8.1770833333... We now must round this to the nearest hundredth. This makes our final answer 8.177 [tex]in^3[/tex].

A circle has a circumference of 37 millimeters. What is the circle's
radius? Use 3.14 for pi and round your answer to the nearest tenth.
Answer:
5.9
Step-by-step explanation:
To find radius from circumference you need to divide it by pie. So 37 divided by 3.14 is 11.7834394904. This is the diameter. Now divide it by 2, in this case it is 5.89171974522. When you round to the nearest tenth it gives you 5.9. Hope this Helps!

Step-by-step explanation:
Put the one shape and split it into two other shapes. A square and a triangle.
find the areas of both of the shapes and add them together.
5×5=25
5×12=60/2 = 30
25+30=55
Answer:
55 units²
Step-by-step explanation:
The area of this shape would be the area of a square with sides 5 and a triangle with a base of 5 and a height of 12
To find the area of this shape, add the area's of the two shapes
This would be written as:

A fish was at the river-bed at a certain time. After 5 minutes, the water level of the river rose
up 2.4 cm and the water level of the river rose up again 3½cm after 4 minutes. The moment, the fish was at 14.6 cm from the river-bed and 162 cm below water level of the river.
Calculate the original height, in cm, of the water level of the river.
Answer:
170.7 cmStep-by-step explanation:
Let the original water level is x.
Use below equation to find its value:
x + 2.4 + 3 1/2 = 162 + 14.6x + 2.4 + 3.5 = 176.6x + 5.9 = 176.6x = 176.6 - 5.9x = 170.7 cmBeen trying to get help on this for a long time Any help ?
