Answer:
$9.48Step-by-step explanation:
The total amount for the order is
$9.75+$29.99+ $15.00=$54.74
let the money her mother owes her be x
so summing all the amount plus the balance given to her must equal $54.74
so x+40+5.26=54.74
solving fo x we have
x+45.26=54.74
make x subject of formula we habe
x=54.74-45.26
x=9.48

Carmen deposits $4000 into a simple interest account. The interest rate for the account is 4.25%.
Write a function that represents the balance in the account as a function of time t.
answer : f(t) = 4000 + 170t
f(t) = principal + (principal multiplied by interest rate) multiplied by time
f(t) = 4000 + (4000*.0425)t
f(t) = 4000 + 170t
t = number of years
======================================================
Explanation:
We use the simple interest formula which is
i = P*r*t
where in this case,
P = 4000 = amount deposited aka principalr = 0.0425 = decimal form of the 4.25% annual interest ratet = unknown number of yearsWe then get the following
i = P*r*t
i = 4000*0.0425*t
i = 170t
Showing that the amount of simple interest earned is 170 times that of the number of years.
For instance, if Carmen waits t = 10 years, then she earns i = 170*t = 170*10 = 1700 dollars in interest alone.
The expression 170t is the interest only. Add on the original amount deposited to find the total account balance after t years. Therefore, we arrive at 170t+4000 to get the linear function f(t) = 170t+4000
The 170 acts like the slope while the 4000 is the y intercept.
What is the value of p?
Answer
32
(6p-10)
Answer:
p = 7
Step-by-step explanation:
6p - 10 and 32 are vertically opposite angles and are congruent , then
6p - 10 = 32 ( add 10 to both sides )
6p = 42 ( divide both sides by 6 )
p = 7

The science club went on a two day field trip. The first day the members paid $30 for transportation plus $20 per ticket to the planetarium. The second day they paid $95 for transportation +17 per ticket to the Geology museum. Write an expression to represent the total cost and dollars for two days for the N members of the club
Answer:
T=125+37NStep-by-step explanation:
let the number of members in the club be N
The first day the members paid
$30 for transportation plus $20 per ticket to the planetarium.
cost= 30+20N
The second day the members paid
$95 for transportation plus $17 per ticket to theGeology museum.
cost= 95+17N
total cost is
T= 30+20N+ 95+17N
T=30+95+20N+17N
T=125+37N
An expression to represent the total cost and dollars for two days for the N members of the club is
T=125+37N
why is the length of segment BD is the same as the length of segment AB ?
Any point on the outside edge of a circle from the center of a circle would be the radius, which would be the same distance all the way around. The outer edge of the larger circle goes through the dot labeled B, which is the center of the smaller circle, therefore any distance from B to the outer edge would be the same.
The length of segment BD is the same as the length of segment AB because any distance from B to the outer edge would be the same.
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
Any point on the outside edge of a circle from the center of a circle will be the radius, which would be the same distance all the way around.
The outer edge of the larger circle goes through the dot labeled B, which means the center of the smaller circle.
Therefore any distance from B to the outer edge would be the same.

Mrs. Margarita has a garden shaped like a half-shaped circle with a diameter of 55 m. What's the area of Mrs. Margarita's garden? (Give your answer correct to 2 decimal places)
Answer:
Area of Mrs. Margarita's garden = 1188.39 m²
Step-by-step explanation:
Using the most basic formula to solve this question i.e. Area of circle. We know that: Area of of circle = πr². But in problem we are provided with a half shaped circle. Means we need to use the half of the area of circle or you can say semi-circle.
Area of semi-circle = 1/2 × πr²Now, read the question again. Mrs. Margarita has a garden shaped like a half-shaped circle with a diameter of 55 m. Given diameter is 55 m and we know that radius is half of the diameter. So, radius is 55/2 m. Rest what we need to do is substitute the values and do the rest calculations.
Let's dive in!
Area of Mrs. Magarita's garden = Area of semi-circle or area of half-shaped circle= 1/2 × 22/7 × 55/2 × 55/2
= 11/7 × 55/2 × 55/2

The water level, w, in feet, of a river after a rainstorm is a function of the time, t,
,
in hours, since the storm began. The table below shows the water level readings collected at different times
Choose the linear function that models the data in the table.
The water level in the river is an illustration of a linear function
The linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]
How to determine the equation of the water level?From the complete question, we have the following table:
t w
1 18.7
1.5 19.1
Start by calculating the slope (m)
[tex]m = \frac{w_2 - w_1}{t_2 -t_1}[/tex]
This gives
[tex]m = \frac{19.1 - 18.7}{1.5 - 1}[/tex]
Evaluate
[tex]m = 0.8[/tex]
The equation is then calculated as:
[tex]w = m(t - t_1) + w_1[/tex]
So, we have:
[tex]w = 0.8(t - 1) +18.7[/tex]
Expand
[tex]w = 0.8t - 0.8 +18.7[/tex]
[tex]w = 0.8t + 17.9[/tex]
Hence, the linear function that models the data in the table is [tex]w = 0.8t + 17.9[/tex]

Eden has a part time job. She gets paid £7. 20 per hourthis week she worked for 18 1/2 hourswork out Eden's total pay for this week
Answer:
$133.20
Step-by-step explanation:
Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.
1. Multiply 7.20 by 18 to get 129.60
2. Multiply 0.50 by 7.20 to get 3.60.
3. Add 129.60 and 3.60 together to get the answer, 133.20.
In Fig. 7.2, a find the value of y when x = -2-5,
Answer:
Given equation: y = x² + 2x - 3
If you wish to find the values of y when x = -2 and x = -5:
When x = -2:
⇒ y = (-2)² + 2(-2) - 3
⇒ y = 4 - 4 - 3
⇒ y = -3
When x = -5:
⇒ y = (-5)² + 2(-5) - 3
⇒ y = 25 - 10 - 3
⇒ y = 12
If you wish to find the value of y when x = -2-5:
When x = -2-5 ⇒ x = -7
⇒ y = (-7)² + 2(-7) - 3
⇒ y = 49 - 14 - 3
⇒ y = 32
Answer:
y = 32
Step-by-step explanation:
Given :-
y = x² + 2x - 3
x = -2-5 = -7
To Find :-
y
Inputting the value of x :
y = (-7)² + 2(-7) - 3
y = 49 - 17
Solution :-
y = 32

The lines are parallel. Find x.
Answer:
As the lines are parallel, it shows that the two lines form 180° because they are angles on the same side of the transversal. A transversal is a line that bisects two lines.
Here,
(20x + 5)° + (24x - 1)° = 180°
=> (20x + 24x)° + (5 + (-1) )° = 180°
=> 44x° + 4° = 180°
=> 44x = (180 - 4)°
=> x = 176 / 44
=> x = 4
Therefore, x = 4 is the solution of the equation.

find the value of x.
A. 1
B. 5
C. 7
D. 8
Answer:
x is equal to 5
Step-by-step explanation:
78 = 12x + 18
12x + 18 = 78
12x = 78 - 18
12x = 60
x = 60/12
x = 5
btw i made 78 equal to 12x + 18 because it is parallel. they both equal the same (i think its called parallel. idrk)
X is equal to 5
78=12x+18
12x=78-18
12x=60
X=60/12
X=5
