It depends on how many dimes are in the piggy bank. It could be any answer that didn't have a 5 in the tenths place. For example, it couldn't be a number like $1.05 because any whole number multiplied by 10 would end in a 0
There are 20 sweets in a box.
x of the sweets are red.
The rest of the sweets are yellow.
Tom takes at random a sweet from the box.
Write down an expression, in terms of x, for the probability that Tom takes a yellow sweet.
Answer:
[tex]probability \: of \: getting \: red \: sweets = \frac{x}{20} \\ probability \: of \: getting \: yellow \: sweets \: = \frac{(20 - x)}{20} [/tex]
The probability of getting red sweets is x/20 and the probability of getting yellow sweet is (20-x)/20.
What is a probability?Probability is about estimating or calculating how likely or 'probable' something is to happen.
Given that x is the number of red sweets.
The total number of sweets is 20.
The number of yellow sweets = 20 - x.
The probability of getting a red sweet is given by
P(x) = x/20
The probability of getting a yellow sweet is given by
P(20-x) = (20-x)/20
Hence, x/20 is the probability of getting a red sweet and (20-x)/20 is the probability of getting yellow sweet.

Which expression is equivalent to 2x^2−18?
Answer:
2x² - 18 = 2(x² - 9) = 2(x - 3)(x + 3)
Step-by-step explanation:
the vertices of xyz are x (1,-4)
Answer:
5. The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)
6. The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)
Step-by-step explanation:
If the point (x, y) translated by T → (h, k), then its image is (x + h, y + k)
#5
In ΔXYZ
∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)
∵ T → (-4, -3)
∴ h = -4 and k = -3
→ Use the rule above to find the image of the vertices of the Δ
∵ X' = (1 + -4, -4 + -3)
∴ X' = (-3, -7)
∵ Y' = (-2 + -4, -1 + -3)
∴ Y' = (-6, -4)
∵ Z' = (3 + -4, 1 + -3)
∴ Z' = (-1, -2)
∴ The vertices of ΔX'Y'Z' are (-3, -7), (-6, -4), (-1, -2)
#6
In ΔXYZ
∵ X = (1, -4), Y = (-2, -1), Z = (3, 1)
∵ T → (5, -3)
∴ h = 5 and k = -3
→ Use the rule above to find the image of the vertices of the Δ
∵ X' = (1 + 5, -4 + -3)
∴ X' = (6, -7)
∵ Y' = (-2 + 5, -1 + -3)
∴ Y' = (3, -4)
∵ Z' = (3 + 5, 1 + -3)
∴ Z' = (8, -2)
∴ The vertices of ΔX'Y'Z' are (6, -7), (3, -4), (8, -2)

Answer:
Angle 6=57 angle 5= 123
Step-by-step explanation:
angle 6 is congruent to angle 3, which is 57 degrees
To find angle 5, we look at both angles 5 and 6's lines. The lines show us that both angles equal to 180, so we subtract 57 from it.

Answer:
1
Step-by-step explanation:
Hello :)
So to answer this problem, we can use the rise over run formula.
The rise is the difference of any two y values.
The run is the difference of the x values from the same two y values.
This question gives us 1,-2 and 3,0
We can use them for the formula:
-2 - 0 divided by 1 - 3

4,9, 16, 25, 36,
Answer:
[tex]a_{n}[/tex] = (n + 1)²
Step-by-step explanation:
The terms are square numbers with each term shifted to the right by 1
That is 1, 4, 9, 16, 25, 36, .....
Thus to obtain 4 in the first position, then
n = 1 → (1 + 1)² = 2² = 4
To obtain any term add 1 to its position in the sequence, that is
[tex]a_{n}[/tex] = (n + 1)²
I dont know why it says im in high school im in middle school. But anyways can someone please explain how to get percentage.
Answer:
Step-by-step explanation:
To change a decimal into a percent you multiply by 100.
If there is a fraction that you need to convert into a percent. Completely divide the fraction. 4/5 = 0.8 then multiply by 100 you get 80%. This means that 4 is 80% of 5
Answer:
how to get a percentage from a decimal is when you take the decimal point and move it twice to the left
Step-by-step explanation:
for example
.07 = 7%
does that make sense?
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b. Her work is shown below.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
Which best describes the error in Tawanna’s solution?
Tawanna factored one or both pieces of the expression incorrectly.
Tawanna did not include each factor in the GCF.
Tawanna should have used each common factor once.
Tawanna included only one of the variables in her solution.
Mark this and return
Answer:
Tawanna should have used each common factor once.
Step-by-step explanation:
Tawanna is asked to find the GCF of each term in the expression 2 a b + 8 b.
Factors of 2ab: 1, 2, a, and b
Factors of 8b: 1, 2, 4, 8, and b
GCF: (1) (1) (2) (2) (b) (b)
GCF = Greatest common factor
She has calculated the GCF incorrectly as she should use each common factor once only. But she has taken all the common factors twice which is wrong.
Hence, the error in Tawanna’s solution is that "Tawanna should have used each common factor once.". Hence, the correct option is (c).
Answer:
C - Tawanna should have used each common factor once.

© The ratio of boys to girls in a class is 5:4. There are 36 students in the class. How many
students are girls?
Answer:
16
Step-by-step explanation:
[tex]no \: of \: girls = \frac{4}{5 + 4} \times 36 \\ \\ = \frac{4}{9} \times 36 \\ \\ = 4 \times 4 \\ \\ = 16[/tex]
Answer:
Step-by-step explanation:
let the ratio of boys and girls be 5x and 4x
According to question,
5x+4x = 36
or, 9x= 36
x=4
number of boys = 5x
= 5·4= 20
number of girls = 4x
= 4.4=16
therefore the total no of boys is 20 ans girls is 16
