Answer:
= 100 km
Step-by-step explanation:
Total length = 5/5
Covered length = 2/5
Remaining length = 5/5 - 2/5 = 3/5
If 3/5 = 60 km
What about 5/5 = ?
= 5/5 x 60 x 5/3 (reciprical)
= 60 x 5/3
= 300/3
= 100 km
Covered distance = 100 - 60 = 40 km

Answer: x = 12 degrees.
Step-by-step explanation:
The triangle ABC is a right triangle, which means that it has a right angle of 90 degrees.
This is represented by the small square on the bottom-left corner of the triangle.
The angle DBC is 78 degrees. There is also the angle of ABD, which is represented by X.
The right angle is equivalent to 78 degrees and x. You can represent this in an equation, where the sum of 78 degrees and x = 90 degrees, the right angle:
78 + x = 90
x = 12

Factorise the expression (c+2d)^2-(c+2d)(3c-7d)
Answer:
(c + 2d) • (9d - 2c)
Step-by-step:
Step 1 :
Equation at the end of step 1 :
((c + 2d)2) - (c + 2d) • (3c - 7d)
Step 2 :
Pulling out like terms :
2.1 Pull out c+2d
After pulling out, we are left with :
(c+2d) • ( (c+2d) +( (-1) * (3c-7d) ))
Answer:
(c+2d)(9d - 2c) = [tex]5dc - 2c^{2} + 18d^{2}[/tex]
Step-by-step explanation:
[tex](c+2d)^{2} - (c+2d)(3c-7d)[/tex]
[tex](c+2d)(c+2d) - (c+2d)(3c-7d)[/tex]
Both sides have (c+2d) so pull out (c+2d)
Rule: a.b + a.c = a(b+c)Rule: a.b - a.c = a(b-c)(c+2d) [(c+2d) - (3c-7d)]
(c+2d) [c+2d - 3c +7d]
(c+2d) [-2c + 9d] = (c+2d)(9d - 2c)
Rule: (a+b)( c + d) = ac + ad + bc + bd ==> Foil method(c+2d)(9d - 2c) = [tex]9dc - 2c^{2} + 18d^{2} -4dc[/tex] = [tex]5dc - 2c^{2} + 18d^{2}[/tex]

Step-by-step explanation:
Jen and Holly are on the Athletic council and want to put a blow up version on the school mascot in the parking lot. They need to tie it down.
Jen’s rope is 7.8 m long and makes an angle of 360 with the ground. Holly’s rope is 5.9 m long. The wind is really strong so they will secure both ropes to the left of the mascot. How far to the nearest tenth of a metre, is Jen from Holly?
Answer:
2.6 m
Step-by-step explanation:
In the attached diagram
Consider Triangle ABC
[tex]\sin36^\circ =\dfrac{|BC|}{7.8} \\|BC|=7.8*\sin36^\circ\\|BC|=4.5847$ m[/tex]
Our goal is to determine the distance of Jen (at point A) to Holly (at Point D).
In Triangle ABC
[tex]\cos 36^\circ =\dfrac{|AC|}{7.8} \\|AC|=7.8*\cos36^\circ\\|AC|=6.3103$ m[/tex]
In Triangle BDC
Applying Pythagoras Theorem
[tex]|BD|^2=|BC|^2+|CD|^2\\5.9^2=4.5847^2+|CD|^2\\|CD|^2=5.9^2-4.5847^2\\|CD|^2=13.7905\\|CD|=\sqrt{13.7905}=3.7136$ m[/tex]
Now, |AC|=|AD|+|DC|
6.3103=|AD|+3.7136
|AD|=6.3103-3.7136
|AD|=2.5967
|AD|=2.6m (correct to the nearest tenth of a metre)
The distance of Jen from Holly is 2.6m.
What is the y-value of the vertex of the function f(x)=-(x+8)(x-14)?
3
6
112
121
Answer:
121
Step-by-step explanation:
Given
f(x) = - (x + 8)(x - 14) ← expand factors using FOIL
= - (x² - 6x - 112) ← distribute by - 1
= - x² + 6x + 112
Given a quadratic in standard form. y = ax² + bx + c : a ≠ 0
Then the x- coordinate of the vertex is
[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]
f(x) = - x² + 6x + 112 ← is in standard form
with a = - 1 and b = 6, thus
[tex]x_{vertex}[/tex] = - [tex]\frac{6}{-2}[/tex] = 3
Substitute x = 3 into f(x) for corresponding value of y
f(3) = - (3)² + 6(3) + 112 = - 9 + 18 + 112 = 121
vertex = (3, 121 ) ← with y = 121
Answer:
D. 121

The sum of three and four tenths and a number is six and six tenths.
Answer:
3.2 (and the equation is 3.4 + x = 6.6)
Step-by-step explanation:
the word problem is written as:
3.4 + x = 6.6
we want to solve for x.
to isolate x by itself, subtract 3.4 from both sides. (3.4 - 3.4=0 & 6.6 - 3.4 = 3.2)
now we have x = 3.2
so x equals 3.2

Mike wants to save $1,750 in the next 12 months. He plans to save $150 each month for the first 11 months. What is the total amount of money Mike will save during the first 11 months if he saves $150 each month?
Please need steps
Answer:
$1650
Based on the question, we don't need the information that Mike wants to save 1750 in 12 months.
We just need to focus on how he is saving 150 every month, for 11 months.
150*11=1650
He will save $1650 if he saves $150 every month for 11 months.

The radius of a cylindrical water tank is 4 ft , and its height is 10 ft . What is the volume of the tank?
Use the value 3.14 for , π and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.
Answer:
2010 cu ft to the nearest whole number.
Step-by-step explanation:
Volume = π r^2 h
= 3.14 * 4^3 * 10
= 2009.6
The volume of the water tank is approximately 502 cubic feet.
What is a cylinder?A cylinder is a 3-D figure that has a radius and a height.
The volume of a cylinder is given as πr²h.
Example:
The volume of a cup with a height of 5 cm and a radius of 2 cm is
Volume.
= 3.14 x 2 x 2 x 5
= 62.8 cm³
We have,
The volume V of a cylinder can be calculated using the formula V = πr²h, where r is the radius of the base and h is the height.
Substituting the given values, we get:
V = π (4 ft)² (10 ft)
V = 3.14 (16 ft²) (10 ft)
V = 502.4 ft³
Rounding this answer to the nearest whole number gives a final answer of V = 502 ft^3.
Therefore,
The volume of the water tank is approximately 502 cubic feet.

Step-by-step explanation:
$350 for 49 hours of work
Write an equation, with hours as the variable
$350 = 49h
Divide both sides of the equation by 49 to find the unit rate
h = $7.14
Carmen received $7.14 for each hour she worked.

You pick a card at random. Without putting the first card back, you pick a second card at random.
What is the probability of picking an even number and then picking an even number?
Simplify your answer and write it as a fraction or whole number.
Answer:
2/5
Step-by-step explanation:
Answer:
1/6
Step-by-step explanation:
Out of these four card choices, for the first pick there are two even cards and four cards in total. This means that on the first pick there is a 2/4=1/2 chance that you pick an even card. On the second pick, if you do not replace the card, then there is 1 even card remaining, and 3 cards in total, leaving a probability of 1/3. Multiplying these two probabilities together, you get an overall chance of 1/6. Hope this helps!

A. Inside the circle
Step-by-step explanation:
K(0, 0), U (6, - 4), V ([tex] \sqrt 2,\: 7)[/tex]
In order to determine whether point V lie inside, outside or on the circle, first we will find the distances between points K & U and then K & V.
KU would be radius of the circle.
If KV is smaller than KU, then V will lie inside. If KV is larger than KU, then V will lie outside And If KV = KU, then V will lie ion the circle.[tex]d(KU) = \sqrt{ {(6 - 0)}^{2} + {( - 4 - 0)}^{2} } \\ = \sqrt{ {6}^{2} + {( - 4)}^{2} } \\ = \sqrt{36 + 16} \\ \red{ \bold{ d(KU)= \sqrt{52} }} \\ \\ d(KV) = \sqrt{ {( \sqrt{2} - 0)}^{2} + {( 7 - 0)}^{2} } \\ = \sqrt{ {( \sqrt{2)} }^{2} + {(7)}^{2} } \\ = \sqrt{2 + 49} \\ \purple{ \bold{ d(KV)= \sqrt{51} }} \\ \\ \because \: d(KU) > d(KV) \\ [/tex]

What is Quadratic Equation?
A quadratic equation is a second-order polynomial equation in a single variable x , ax² + bx + c =0. with a ≠ 0. Because it is a second-order polynomial equation, the fundamental theorem of algebra guarantees that it has at least one solution. The solution may be real or complex.
Given data ,
Let the equation be f ( x )
The equation f ( x ) is x² - 10 = 26
Now , adding 10 on both sides , we get
x² = 36
Taking square roots on both sides , we get
x = ±6
We know , (-6)² = 36 and (+6)² = 36
Therefore , x can have 2 solutions , which is ±6
Hence , the two values which x can have will be +6 and -6
