Answer:
x=[tex]\frac{7}{22}[/tex]
Step-by-step explanation:
To solve for x, you need to isolate it. The first step is dividing by [tex]\frac{2}{7}[/tex] on both sides. Dividing by a fraction is just like multiplying by the reciprocal, so really you are multiplying both sides by [tex]\frac{7}{2}[/tex]. [tex]\frac{1}{11}[/tex] × [tex]\frac{7}{2}[/tex] =[tex]\frac{7}{22}[/tex]

Answer:
x=4 and the solution is not extraneous
Step-by-step explanation:
[tex]\sqrt{2x+1}=3 \\\\2x+1=9 \\\\2x=8 \\\\x=4[/tex]
This solution is not extraneous, because plugging it back in you get:
[tex]\sqrt{2(4)+1}=3 \\\\\sqrt{9}=3 \\\\3=3[/tex]
Hope this helps!
Answer:
X = 4, solution is not extraneous
Step-by-step explanation:
3 = √9
so we get the following comparison;
2X + 1 = 9 (both minus 1)
2X = 8 (divide by 2)
X = 4
if we fill in 4 for X. we get
√2•4+ 1 = √9 = 3 so the solution is not extraneous
If p:q =3/4 :2 and p:r= 1/3 :1/2 find p:q:r Please explain with steps
Answer:
p : q : r = 1 : 8/3 : 3/2
Step-by-step explanation:
p/q = (3/4)/2 = 3/(4*2) = 3/8
=> q = (8/3)p
p/r = (1/3)/(1/2) = (1*2)/(3*1) = 2/3
=> r = (3/2)p
=> (p, q ,r) = (p, (8/3)p, (3/2)p)
=> p : q : r = 1 : 8/3 : 3/2

The slope of a line is 2/3 . What is the slope of a line that is perpendicular to this line?
Answer:
-3/2
Step-by-step explanation:
With perpendicular lines, the slope switches to its reciprocal and and positive/negative sign switches, i.e, the 2/3 will switch to 3/2 and since the original is positive, the new slope will be negative
Answer:
Slope is -3/2
Step-by-step explanation:
The slope of line that is perpendicular to the line should have a slope that is a negative reciprocal of this slope and multiplying both slopes give us -1
=> The slope of this line is 2/3
=> The slope of line perpendicular to it would be -3/2
Multiplying the two slopes:
=> (2/3)*(-3/2)
=> -1
Can I get help with this problem
Answer:
x = 116°
y = 90°
Step-by-step explanation:
∠F = 90°, so arc EDS = 180°.
Therefore, arc EFS = 360° − 180° = 180°. Which means ∠D = 90°.
Angles of a quadrilateral add up to 360°, so:
x + 90° + 90° + 64° = 360°
x = 116°
Answer:
The value of x is 116° and y = 90°
Step-by-step explanation:
Given that opposite supplementary angles in a cyclic quadrilateral is 180° :
[tex]x + 64 = 180 \\ x = 180 - 64 \\ x = 116[/tex]
[tex]y + 90 = 180 \\ y = 180 - 90 \\ y = 90[/tex]
if the lateral edge of a regular tetrahedron is 8 cm, then it's altitude is?
Answer:
The altitude is 6.53 cm
Step-by-step explanation:
A regular tetrahedron is a triangular pyramid having equilateral triangular faces, therefore we have;
Sides of the equilateral triangle = 8 cm
Given that the slant height, the edge of the tetrahedron, and half the base edge of the tetrahedron form a right triangle, we have;
The slant height, h = √(8² - (8/2)²) = √48 = 4×√3
The segment representing the altitude, H, of the tetrahedron forms a right triangle with the edge of the tetrahedron and 2/3×h
Therefore;
8² = H² + (2/3×4×√3)²
H² = 8² - (2/3×4×√3)²
H² = 64 - 64/3 = 128/3
The altitude H = √(128/3) = √6×8/3 = 6.53 cm.

Sam is baking cakes at her parents' bakery. She gets paid $20 a week in addition to $5 for every cake she bakes. She made $50 this week. Write an equation to show how many cakes Sam baked this week. 20 − 5x = 50 50 + 5x = 20 20 + 5x = 50 50 − 5x = −20
Answer:
20 + 5x = 50
Step-by-step explanation:
Let the number of cakes Sam baked this week be x
Total amount he received this week = $50
Amount he receives each week = $20
Amount he receives for baking one cake = $5
Amount he would receive for baking x cakes = $5x
Equation: 5x + 20 = 50
Answer:
20 + 5x = 50
Step-by-step explanation:
Let x be the number of cakes
Amount paid per cake = $5
Amount paid for "x" cakes = 5*x = 5x
Basic payment per week = $20
Amount paid that week = 20 + 5x
20 + 5x = 50

Mr Lee wants to top up his oil tank,the oil tank can take up to 1200liters .The tank already has 450l of oil. The price of oil is 81.5p per litre. Mr Lee gets a 7.5% discount on the price of the oil. How much discount does Mr Lee get on this perchance. Answer in £
Answer:
£45.84375
Step-by-step explanation:
To top up the tank he needs:
1200 - 450 = 750 liters
Since the price of oil is 81.5p per liter and he gets a 7.5% discount, the discount per liter is:
81.5 x 7.5/100 = 6.1125p
Since he needs 750 liters, the discount in total is:
6.1125 x 750 = 4584.375p
Since 1p = £0.01
The discount he gets in £ is:
4584.375 x 0.01 = £45.84375
The figure shows the dimensions of a wall having a door and window of a room. Write an algebraic expression for the area of the wall to be painted. PLEASE FAST
Answer:
Area of the wall to be painted = (11x² + 12x) square units
Step-by-step explanation:
The figure that should be attached to this question is missing. The figure was obtained and is attached to this solution provided.
From the image attached, it is given that the dimension of the rectangular wall to be painted is (4x+3) by (4x), the dimensions of the window is (2x) by (x) and the dimensions of the door is (x) by (3x).
Since, the window space and the door space cannot be painted along with the wall, the Area of the rectangular wall that will be painted will be given by the expression
(Total Area of the rectangular wall) - [(Area of window space) + (Area of door space)]
Area of a rectangular figure = Length × Breadth
Total area of rectangular wall = (4x+3) × 4x = (16x² + 12x) square units
Area of window space = (2x) × (x) = (2x²) square units
Area of door space = (x) × (3x) = (3x²) square units
Area of the wall to be painted = (16x² + 12x) - (2x² + 3x²)
= 16x² + 12x - 5x²
= (11x² + 12x) square units

The improper fraction of 1(1/3) is 4/3.
What is a fraction?A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.
We have two types of fractions.
Proper fraction and improper fraction.
A proper fraction is a fraction whose numerator is less than the denominator.
An improper fraction is a fraction where the numerator is greater than the denominator.
Example:
1/2, 1/3 is a fraction.
3/6, 99/999 is a fraction.
1/4 is a fraction.
We have,
1 and 1/3
An improper fraction means the numerator is greater than the denominator.
So,
1 and 1/3
= 1(1/3)
= (3 x 1 + 1) / 3
= 4/3
4 > 3 so it is an improper fraction.
Thus,
The improper fraction of 1(1/3) is 4/3.

what is the area of the figure below use 3.14 for pie
Answer:
Answer CL 586 cm^2
Step-by-step explanation:
Hello. It's pi, not pie.
The area of the triangle is A1 = (1/2)(base)(height) = (1/2)(18 cm)(7 cm), or
A1 = 63 cm^2.
The area of the rectangle is A2 = (base)(height) = (18 cm)(22 cm) = 396 cm^2.
The area of the semicircle is A3 = (1/2)(pi)(9 cm)^2 = 3.14(81 cm^2)(1/2) = 127 cm^2
Thus, the total area of the figure is A = 127 cm^2 + 396 cm^2 + 63 cm^2, or
586 cm^2 approximately.

Find the 14th term of the geometric sequence 10, 20, 40, ...
The 14th term of the geometric sequence 10, 20, 40, ... is 81920.
What is geometric sequence?"A geometric sequence is a special type of sequence. It is a sequence in which every term (except the first term) is multiplied by a constant number to get its next term."
The geometric sequence formulas include the formulas for finding its nth term and the sum of its n terms. We will see the geometric sequence formulas related to a geometric sequence with its first term 'a' and common ratio 'r' (i.e., the geometric sequence is of form [tex]a, ar, ar^{2},ar^{3} ,.............[/tex]).

Does the table represent a function? why or why not? HELP WANTEDD
Answer:
C no, because one x value corresponds to two different y values
Step-by-step explanation:
The x value of 3 goes to two different y values
This means this cannot be a function
This is not a one to one correspondence
Answer: C
Step-by-step explanation: In order for a table to represent a function each x-value needs to correspond to exactly 1 y-value.
Notice that in the table, the 3 appears twice and it corresponds to a 5 in one case and it corresponds to a 6 in another case.
Since the x-value of 3 corresponds to more than 1 y-value,
no, this table does not represent a function.
