Answer: 25 nickels
Step-by-step explanation:
EQUATIONS:
quantity: n + d = 63
value: 5n + 10d = 505
-------------------------
Divide thru the 2nd equation by 5 to get:
n + 2d = 101
----------------
Subtract that from the 1st equation:
-d = -38
d = 38 (# of dimes)
---------------
Substitute that into n+d=63 to solve for "n":
n + 38 = 63
n = 25 (# of nickels)

Sonya goes into a newsagent's. She buys 3 items. They cost £1.25, 45p and £2.50. Sonya uses her calculator to check the total cost. The calculator gives this answer. 4.2 Is this answer correct or no?
Answer:
The answer is correct
Step-by-step explanation:
Sonya purchases three items
Cost of 1 Item - £1.25
Cost of 2 item - 45p
Cost of 3 item - £2.50
The total cost of all three items is equal to
[tex]1.25 + 0.45 + 2.50 = 4.20[/tex]
Hence, the answer is correct

If 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(5a, 2a), where a > 0, what is the value of a?
Answer:
The value of a is 80
Step-by-step explanation:
The distance of a point [tex](x_o,y_0)[/tex] from the y-axis can be written as [tex]d_y=|x_o|[/tex] because the x-coordinate of the y-axis is zero.
Similarly, the distance of a point from the x-axis can be written as [tex]d_x=|y_0|[/tex]
since the y-coordinate of the x-axis is zero.
In this problem:
- The distance of the point A (−30, −45) from the y-axis can be written as
[tex]d_A=|-30|=30[/tex]
- The distance of point B (5a,2a) from the x-axis can be written as
[tex]d_B=|2a|=2a[/tex]
Since [tex]a>0[/tex]
We are told that 2/3 of the distance from the y-axis to point A (−30, −45) is equal to 1/4 of the distance from the x-axis to point B(a, a), which means
[tex]\frac{2}{3}d_A=\frac{1}{4}d_B[/tex]
Therefore,
[tex]\frac{2}{3}(30)=\frac{1}{4}(2a)[/tex]
And solving for a,
[tex]20=\frac{1}{2}a\\a=40[/tex]
Calculate the slope of the line on the graph using the
formula:
72-V1
m
X2 - X
The slope of the line is
_____m/s.
Given:
The graph of a line which represents position (m) at time (s).
To find:
The slope of the line.
Solution:
Formula for slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph it is clear that the line passes through two points (0,0) and (1,4).
Using the above formula, we get
[tex]m=\dfrac{4-0}{1-0}[/tex]
[tex]m=\dfrac{4}{1}[/tex]
[tex]m=4[/tex]
Therefore, the slope of the line is 4 m/s.

Find the value of x in the figure below.
Step-by-step explanation:
75 is equal to opposite angle of x.
so,
75° +65°+ x=180°( by all angles sum)
140°+x=180°
x=180°-140°
x=40°
Answer:
x = 40
Step-by-step explanation:
75 + 65 = 140
180 - 140 = 40

1. The graph of linear function f contains the point (4, 4) and has a slope of 1/2
-
What is the zero of f?
O A. 2
OB. 4
OC -2
OD.-4
Answer:
A. 2Step-by-step explanation:
Function f will have formula:
f(x) = 1/2x + b, where 1/2 is slope and b is y-interceptUsing point (4, 4) we find b:
4 = 1/2*4 + b4 = 2 + bb = 4 - 2b = 2Zero of f is 2
Correct choice is A. 2

An after school music program has 15 out of 50 students participating. Write 1550 as a decimal and as a percent. Decimal- Percent-
Answer:
0.3
30%
Step-by-step explanation:
To write 15/50 as a percent, you have to multiply the fraction by 100
[tex]\frac{15}{50}[/tex] x 100
dividing 100 by 50 gives 2
15 x 2 = 30%
to convert 15/50 to a decimal, first simply the fraction.
Both the numerator and denominator can be divided by 5
3/10
the next step is to divide the numerator by the denominator
