What is the area of the triangle?
Answer:
16
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh
A = 1/2 (4)*8
A = 16
Answer:
The area of the triangle is 16 cubic units
Step-by-step explanation:
The formula for the area of a triangle is like the same as a rectangle, just in half. So, by doing 8x4, you get 32. Divide 32 by 2 to get 16.

A 14 inch pizza (diameter is 14) was cut in to 8 pieces. What is the angle measure of each slice? *
Answer:
The angle for each slice is 45 degrees.
Step-by-step explanation:
In order to calculate the angle of each slice, we first need to calculate the total area of the pizza, because we will use that to find the area of each slice and as a result it's angle. To calculate the area of the pizza we must use:
pizza area = pi*r²
r = d / 2 = 14 /2 = 7 inches
pizza area = pi*(7)² = 153.86 square inches
Since the pizza was divided in 8 pieces, the area of each piece is given by the area of the pizza divided by the number of slices. We have:
slice area = pizza area / 8 = 153.86 / 8 =19.2325 square inches
Each slice is a circle sector, therefore it's area is given by:
slice area = (angle*pi*r²)/360
Therefore we can solve for angle:
19.2325 = (angle*pi*7²)/360
angle*pi*49 = 6923.7
angle = 6923.7 / pi*49 = 45 degrees
The angle for each slice is 45 degrees.

ef=55
Step-by-step explanation:
The value of r in the given parallelogram is 9 and the length of EF is 55 units.
What is a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
Given that, in a parallelogram FCDE sides DC and FE are parallel, and sides FC and ED are parallel. The length of CD is 4r + 19, the length of DE is 8r + 3, and the length of FC is 9r - 6.
Since, we know that,
Opposite side of a parallelogram are parallel and equal, therefore,
FC = DE and DC = FE
Therefore,
8r+3 = 9r-6
r = 9
Therefore,
FE = DC = 4r+19
= 36+19
= 55
Hence, the value of r in the given parallelogram is 9 and the length of EF is 55 units.

Answer:
f(x)=2x
Step-by-step explanation:
You can get your (a)term by finding rise/run, and there is no y-intercept so the (b)term is not known. Thus you get f(x)=2x.
The equation of the line is [tex]y = 2 x[/tex]
From the graph, we have the following ordered pairs
(0,0) and (5,10)
The equation of the line is calculated using
[tex]y = \frac{y_2 -y_1}{x_2 -x_1} \times (x -x_1) + y_1[/tex]
So, we have:
[tex]y = \frac{10 - 0}{5 - 0} \times (x -0) + 0[/tex]
[tex]y = \frac{10}{5} \times (x -0)[/tex]
[tex]y = 2 \times x[/tex]
Evaluate the product
[tex]y = 2 x[/tex]
Hence, the equation of the line is [tex]y = 2 x[/tex]

Debra works as a tutor and as a waitress for $11 an hour. THIS MONTH, she worked a combined total of 97 hours at her two jobs. Let t be the number of hours Debra worked as a tutor this month. WRITE AN EXPRESSION FOR THE COMBINED TOTAL DOLLAR AMOUNT SHE EARNED THIS MONTH.
Answer:
(x -11) * t + 1067
Step-by-step explanation:
We know that in her tutoring job she earns x amount of money and how waitress earns $ 11 / hour.
They give us the combined number of hours that he works with all the jobs, which is 97, but from here we can say that in the time that he does NOT work as a tutor it is actually 97 - t.
Total earned this month = x * t + 11 * (97 -t)
Total earned this month = x * t + 1067 - 11 * t = (x -11) * t + 1067
Kamil is saving up to buy a model of Big Ben costing £30 when he visits London. So far he has saved €15.00. How much more money does he need to save? (Show your answer in € and in £).
Answer:
€18.40 or £16.53.
Step-by-step explanation:
Kamil is saving up to buy a model of Big Ben costing £30 when he visits London.
He has saved €15.00.
First, we have to convert his savings to Pounds(£) and then, subtract that from the amount he needs.
€1 = £0.90
€15 = 15 * 0.9 = £13.47
So, Kamil has saved £13.47.
Therefore, the amount he has left to save is:
£30 - £13.47 = £16.53
To find this amount in Euros, we convert it to Euros:
£1 = €1.11
16.53 = 16.53 * 1.11 = €18.40
He has to save €18.40 or £16.53.
Answer:
€18.3 or £16.49
Step-by-step explanation:
Kamil needs to save £30 to buy Big Ben. Current rate of conversion from pound to euro is £1 = €1.11. If the money is converted from pound to euro, you multiply it by 1.11.
Therefore £30 = € (30 * 1.11) = €33.3
If he has saved €15 he needs to save an extra of €(33.3 - 15) = €18.3
He needs to save €18.3
€18.3 to pound using the Current rate of conversion from euro to pound = £(18.3/1.11) = £16.49
Molly works at an electronics store. Her last customer purchased a DVD player for $61.29 and five DVDs for $59.31, including taxes. If the customer paid her with two \$100 bills, how much change should she give him?
Answer:
$79.4
Step-by-step explanation:
Add up both of the prices.
61.29 + 59.31 = 120.6
Subtract that from the 200.
200 - 120.6 = 79.4
Asa is supposed to floss his teeth using 18" of floss daily. He began a new roll 50' on March 17th. If he still has 2 feet of floss left after flossing on August 2nd, how many days has he forgotten to floss?
Answer:
Asa forgot to floss for 106 days.
Step-by-step explanation:
First of all, we will start by writing out the details we are given clearly.
Length of floss used per day = 18 inches
Original length of floss bought for use = 50 ft = 600 inches
Number of days between March 17th and August 2nd = 138 days
Length of floss left after August 2nd = 2 feet = 24 inches
From this, we can clearly calculate the length of floss used.
This will be original floss length - length of floss remaining = 600 - 24 = 576 inches
Length of floss used = 576 inches
If Asa used 18 inches per day, we can find the number of days he flossed by dividing the length used in total by the length used per day.
That will be 576/18 = 32 days
if Asa flossed for only 32 days, the number of days he didn't floss is 138 - 32 =106 days
Hence, Asa didn't floss for 106 days.
y = 2 and 7x - 3y = -34
Answer:
7x - 3y = -34
7x - 3(2) = -34
7x - 6 = -34
7x - 6 + 6 = -34 + 6
7x = -28
7x/7 = -28/7
x = -4
7(-4) - 3y = -34
-28 - 3y = -34
-28 + 28 - 3y = -34 + 28
-3y = -6
-3y/-3 = -6/-3
y = 2

B. Size of table cloth required by a circular table
C. Amount needed to fence around a circular garden
D. An amount of water circular swimming pool holds
Answer:
C. Amount needed to fence around a circular garden
Step-by-step explanation:
The Circumference of a circle can be referred to as the length of the circle. It also called the perimeter of a circle.
The circumference of a circle can be defined as the distance roundabout a circle.
The circumference of a circle is calculated mathematically as:
a) 2πr or
b) πD
Where r = radius of the circle.
D = Diameter of the circle
From the above question, the situation can be modeled by circumference of a circle based on the definition that the circumference of a circle is the distance around a circle is Option C. "Amount needed to fence around a circular garden"

A motorist travels between two towns. It usually takes 6 hours when travelling at a certain speed. He finds that if he reduces his speed by 15 km/hr his journey will take 1 hour more. Find his usual speed.
Answer:
His usual speed is 105 km/hr.
Step-by-step explanation:
Let his usually speed be s km/hr and the distance between the towns be d km. So we have the equations:
s = d/6
s - 15 = d / (6 + 1)
from the first equation:
d = 6s and from the second:
d = 7(s - 15)
Eliminating d we get:
6s = 7(s - 15)
7s - 105 = 6s
s = 105.
