Answer:
A) R24.10
B) R25.90
((ASSUMING THERES NO TAXES WITH THE PAYMENT))
Step-by-step explanation:
A)
first add up the costs of each item to get the ttal cost with addition as follows...
9.50 + 0.50 + 2.75 + 11.35 ((Adding like terms by adding 0.50 to 9.50 equaling 10.00))
10.00 + 2.75 + 11.35 ((adding the more simple options togeter since .75 is a more common fraction at 3/4))
12.75 + 11.35 ((finnishing off the system by adding the last two numbers together equaling to 24.10))
therefore Thabo spent a total of 24.10
B)
to find out the change, all we need to do is subtract the total cost from the total amount Thabo used to pay as shown below
50.00 - 24.10
in conclusion, Thabo would have R25.90 in change from the transaction ((assuming theres no tax))

Find the area of the shaded region
Answer:
68 units sq
Step-by-step explanation:
You have to find the total area of all the shapes and subtract the unshaded.
(9 + 17) * 8 / 2, formula
26 * 4 = 104
Then find the unshaded part
9 * 8 / 2
9 * 4
= 36
104 - 36 = 68
Answer:
68
Step-by-step explanation:
The formula of a trapezoid is [tex]A = \frac{a+b}{2} h[/tex]
Use the values given in the equation:
[tex]A = \frac{17+9}{2} *8[/tex]
A = 13*8
A=104 (This the area of the overal trapezoid)
To find the area of the inner unshaded triangle, simply multiply 9 (Base) times height (8) * 1/2 to get 36
Then subtract 36 from 104 and you get 68

help???????????????????????????????
Answer:
a) - y = 30°,x = 70°
b)- y = 105°,x = 75°
c)- x = 25°
d)- x = 116°
Step-by-step explanation:
a) =
80 + 70 + y = 180 (co-interior angles)
or, y = 180 - 150
so, y = 30°
Now,
x = 70° (alternate angles)
b) =
y + 75 = 180° (co-interior)
(y = angle which is supplement to 75)
y = 180° - 75°
so, y = 105°
Now,
x + y = 180° (co-interior angles)
or, x = 180° - 105°
so, x = 75°
c)=
180° - 5x = 55° (corresponding angles)
or, 5x = 180° - 55°
or, 5x = 125°
or, x = 125°/5
so, x = 25°
d)=
64° + x = 180° (co-interior angles)
x = 180° - 64°
so, x = 116°
Answer:
See below ~
Step-by-step explanation:
a)
80 + 70 + y = 180 [co-interior angles are present]y + 150 = 180y = 30°x and 70° are alternate angles ⇒ x = 70°b)
y + 75 = 180° [Check line 1 of (a)]y = 105°x + y = 180° x + 105° = 180°x = 75°c)
55° + 5x = 180° [Angle adjacent to 55° corresponds to (5x)°]5x = 125°x = 25°d)
64° + x = 180° [Check line 1 of (a)]x = 116°For each of the following equations, say which one (d) has two rational solutions, (e) has two irrational
solutions, and (f) has two non-real solutions. Each answer (d, e, and f) is used once.
to solve this equation
[tex]x { }^{2} + 3x - 40 = 0[/tex]
we first identify it as quadratic and to solve we find two numbers that can multiply to get -40 and add to get positive three [tex](x - 5)(x + 8)[/tex]the factors being-5 and positive 8 satisfied the condition now to apply zero product principle [tex](x - 5) = 0 \: and \: (x + 8) = 0[/tex]from the equation above in (x-5)=0 we subtract 0 from both places and it literally reads [tex]x = + 5[/tex]for the second the same is done [tex]x = - 8[/tex]now for second question[tex]x^{2} + 3x + 1[/tex]not forgetting the zero. open two brackets and find no that can add to get 3 and multiply to get 1[tex](x + 1)(x + 1)[/tex]the answer being x=-1 and x=-1652,951 rounded to the nearest thousand?

[tex]\frac{4\left(3-\sqrt{7}\right)}{\left(3+\sqrt{7}\right)\left(3-\sqrt{7}\right)}[/tex]
Now, we an see that the denominator is in the form of the algebraic identity: (x + y) (x - y) = x² - y². So,
[tex]\frac{4\left(3-\sqrt{7}\right)}{3^{2}-\left(\sqrt{7}\right)^{2}} \\= \frac{4\left(3-\sqrt{7}\right)}{9-7} \\= \frac{4\left(3-\sqrt{7}\right)}{2} \\[/tex]

Hopefully this helps you
- Matthew
Bartering was an early way that people exchanged goods.
☆Explanation:In earlier times money was not there,so people used to follow a system in exchange of goods. This system was known as barter system. In barter system commodities were exchanged against commodities. ¤ Example:-Let's imagine a situation between "A" and "B". Suppose "A" wants rice and have sugar. On the other hand "B" has rice and he wants sugar. So,there will be exchange between "A" and "B" where "A" will give sugar to "B" and "B" will give rice to "A".
This procedure of exchanging goods is known as barter system.Hope it helpsin a survey 15 high school students said they could drive 15 said they could not out of 60 college student survey 30 said They Could Dr., Micah concluded that if someone is in college that means in person is more likely to drive is is is micahs conclusion correct explain
no it's not correct
50% can drive and 50% cannot drive... cus the survey is conducted on 50% students... so assuming that 30 students' percentage is 100, 15 can drive and 15 cannot, therefore...
50% can drive and 50% cannot drive

If f(x) = 2x^3- 2x^2 - 14x + 30 and x + 3 is a factor of f(x), then find all of
the zeros of f(x) algebraically.
Answer:
Step-by-step explanation:
First confirm that x = 1 is one of the zeros.
f(1) = 2(1)^3 - 14(1)^2 + 38(1) - 26
f(1) = 2 - 14 + 38 - 26
f(1) = -12 + 38 = + 26
f(1) = 26 - 26
f(1) = 0
=========================
next perform a long division
x -1 || 2x^3 - 14x^2 + 38x - 26 || 2x^2 - 12x + 26
2x^3 - 2x^2
===========
-12x^2 + 28x
-12x^2 +12x
==========
26x -26
26x - 26
========
0
Now you can factor 2x^2 - 12x + 26
2(x^2 - 6x + 13)
The discriminate of the quadratic is negative. (36 - 4*1*13) = - 16
So you are going to get a complex result.
x = -(-6) +/- sqrt(-16)
=============
2
x = 3 +/- 2i
f(x) = 2*(x - 1)*(x - 3 + 2i)*(x - 3 - 2i)
The zeros are
1
3 +/- 2i

17% and now costs £7.20.
How much did it cost before the
increase?
It costs $122.4 dollars before the increase.
How to calculate percentage of a number. Use the percentage formula: P% * X = YConvert the problem to an equation using the percentage formula: P% * X = Y.P is 17%, X is 7.20, so the equation is 17% * 7.20 = Y.Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10.
Therefore, It costs $122.4 dollars before the increase.
