A pizza is cut into pieces. Kevin takes 1/4 of the total pieces. Keith takes one piece less than twice the number of pieces Kevin took. How many of pizza are left ?
a. 1/4x
b. 1/4x+1
c. 1/2x+1
d. 3/4x-1
Answer: I believe the answer is d or b
Step-by-step explanation:
The number of pizza pieces left is (x + 4) / 4. Option c
How to determine the number of pizza pieces leftLet's assume the total number of pizza pieces is represented by 'x'.
Kevin takes 1/4 of the total pieces, which is (1/4) * x = x/4.
Keith takes one piece less than twice the number of pieces Kevin took, which is 2 * (x/4) - 1 = (2x/4) - 1 = x/2 - 1.
To calculate the number of pizza pieces left, we need to subtract the sum of Kevin's and Keith's pieces from the total number of pieces (x):
Leftover pieces = Total pieces - (Kevin's pieces + Keith's pieces)
= x - (x/4 + x/2 - 1)
= x - (3x/4 - 1)
= x - 3x/4 + 1
= (4x - 3x + 4) / 4
= (x + 4) / 4
Therefore, the number of pizza pieces left is (x + 4) / 4.
The correct option among the given choices would be (c) 1/2x + 1.

Find the value of k if the remainder is 13 when
25 + 4x4 + kx3 + x – 11 is divided by x + 3
Answer:
[tex]k = \frac{322}{27} [/tex]
Step-by-step explanation:
x + 3 = 0 → x = - 3
25 + 4(-3)⁴ + k(-3)³ + (-3) - 11 = 13
25 + 324 - 27k - 3 - 11 = 13
349 - 27k - 14 = 13
349 - 14 - 13 = 27k
349 - 27 = 27k
322 = 27k
k = 322/27

Find the ‘exact’ perimeter of each triangle
Answer:
[tex]\huge\boxed{\sf 8 + 4\sqrt{2} \ cm }[/tex]
Step-by-step explanation:
[tex]\theta = 45 \textdegree[/tex]
opposite = 4 cm
Using tan first to find the adjacent side:
[tex]\displaystyle tan \theta = \frac{opposite}{adjacent} \\\\tan \ 45 = \frac{4}{adjacent}\\\\1 = \frac{4}{adjacent} \\\\Multiply \ 'adjacent' \ to \ both \ sides\\\\adjacent = 4 \ cm[/tex]
Finding Hypotenuse now by using Pythagorean theorem:
[tex](Hyp)^2 = (base)^2 + (perp)^2[/tex]
where base = 4, hyp = 4
(Hyp)² = (4)² + (4)²
(Hyp)² = 16 + 16
(Hyp)² = 32
Take sqrt on both sides
[tex]Hyp = 4\sqrt{2}[/tex] cm
Exact perimeter of triangle:

The diagonal of a quadrilateral shaped field is 24 m and the perpendiculars dropped on it from the remaining opposite vertices are 8 m and 13 m. Find the area of the field.
Put the values
Area:-
[tex]\\ \rm\Rrightarrow \dfrac{1}{2}(24)(8+13)[/tex]
[tex]\\ \rm\Rrightarrow 12(21)[/tex]
[tex]\\ \rm\Rrightarrow 252m^2[/tex]
Answer:
Step-by-step explanation:
Divide the quadrilateral field into two triangles by its diagonal.
Area of a triangle is given by the equation 1/2*base*height.
The top triangle's area = 1/2*24*13 = 156 m^2
The bottom triangle's area = 1/2*24*8 = 96 m^2
Combining, the area of the field = 156 + 96 = 252 m^2

If y varies inversely as x and x is 6 when y is 13, what is x when y is 8? a. 9. 75 b. 3. 69 c. 0. 27 d. 6. 5.
The value of x when y is 8 is 9.75.
It is given that
y ∝ 1/x
y = k/x......(1)
Where k is a constant of proportionality
What is the constant of proportionality?The constant of proportionality is the ratio that relates two given values.
When y =13, x=6
Means, 13 = k/6
k = 78
Putting the value of k in equation (1)
y = 78/ x
8 = 78/ x
x =9.75
Therefore, The value of x when y is 8 is 9.75.

rosa has a goal of running a total of 150 miles this month each day she ran for 6 miles . what expression could rosa use to determine how many miles she has left to run after running for d days
Answer:
miles left = 150 - 6d
Step-by-step explanation:
To create this expression, let 150 be the total number of miles she needs to run. If she runs 6 miles every day, the expression for miles she has left is the total miles - 6* how many days she has been running. Your final expression for miles she has left should be 150 - 6d.

* 4. A circle is divided into ten equal sectors.
a. Find the measure of each central angle.
b. If the diameter is 50 in., find the length of an arc of one of the
sectors.
HELP PLEASE
Answer:
a. Find the measure of each central angle.
The central angle of a circle = 360 °
Now Pie is cut into 10 equal sectors
Angle of each sector is given by
Angle of sector = Total central angle/number of sectors
[tex] = {360}^{0} \div 10[/tex]
[tex] = {36}^{0} [/tex]
Hence , the central angle of one slice of pie is 36°
b. If the diameter is 50 in., find the length of an arc of one of the sectors.
length of an arc of one of the sectors =
[tex] = \frac{1}{n} \times 2\pi \times r[/tex]
[tex]= \frac{1}{10} \times 2\ \frac{22}{7} \times 50[/tex]
[tex] = 31.42 \: in[/tex]
Answer: 36 degrees
Step-by-step explanation:
A circle is 360 degrees.
If you divide 360 degrees by 10, (10 sectors) you get 36.
The answer is therefore 36 degrees. (don't forget your labels!!!)
