Answer:
-278
Step-by-step explanation:
3 x 11 = 33
33 - 78 = -45
-45 x 6 = -270
-270 - 8 = -278
I think I might of did it wrong.... :C
Answer: The number is 14
Step-by-step explanation:
11x - 78 = 6x - 8
11x -6x = -8 + 78
5x = 70
x = 14
Two jets are flying towards each other from airport that are 1200 km apart. One jet is flying at 250 km.h-1 and the other jet at 350 km.h-1 . If they took off at the same time, how long will it take for the jets to pass each other?
Answer: 2 hours
Step-by-step explanation:
The total velocity at which the planes are approaching each other is 350 + 250 = 600 km/h
Since time = distance/velocity, time = 1200km/ 600 km/h = 2 hours.
Give the degree and classify the polynomial by the number of terms.
-x² + 3x - 4
A. degree: 2; trinomial
B. degree: 3; binomial
C. degree: 3; trinomial
D. degree: 2; binomial
Answer:
A. degree: 2; trinomial
Step-by-step explanation:
The degree of a polynomial is the highest degree of a single term. In this example, the highest degree is 2 (-x^2) so the degree of the polynomial is 2. If a term has more than one variable, add all the degrees in the term (e.g. a polynomial with x^2y^3 has a degree of 5).
The classification of a polynomial depends on how many terms there are.

How can you be certain that the angles you have created form a square inside the
circle?
Answer:
Step-by-step explanation:
Make sure that the angles are the same length, also make sure that the diameter of the circle is not smaller than that of the square to find diameter of a circle multiply the radius by 2, to find the radius use this formula
r=C over 2π
By Ensure that its angles are identical, and also ensure that circle's diameter is only smaller than the square because then the circle diameter multiplies the range by 2, so how you can find the [tex]\bold{r=C}[/tex] formula of the radius over [tex]\bold{2\pi}[/tex]
The building process is as follows:
Circle diameter is plotted.The method as described in the perfectly straight central axis of a portion is drawn by the bisector of the right angle of the radius. It is also a circular pattern diameter.The four areas on the circle that result are indeed the square vertices.Please find the attached file.

Which of the following is a result of shifting a circle with equation (x-2)2 +(y-3)2=25 to the left 2 units ?
A.) Both the x- and y-coordinates of the center of the circle increased by 2
B.) Both the x- and y-coordinate of the center of the circle decreased by 2
C.) The y-coordinate of the center of the circle decreased by 2
D.) The x-coordinate of the center of the circle decreased by 2
Answer:
D.) The x-coordinate of the center of the circle decreased by 2
Step-by-step explanation:
(consult the diagram attached below)
Consider a circle
(x - 2)² + (y - 3)² =25
Where (h, k ) = (2, 3) which is the center of the circle.
When we want to move the circle to the left by 2 units, it also means the the center of the circle will move 2 units to the left.
If center of the circle moves 2 units to the left, it means that the x coordinate of the center of the circle will be decreases by 2 units, while y coordinate will remain the same.
Hence the new coordinate for the center of the circle is (2-2, 3) = (0, 3)
The new equation of circle will be:
(x - 0)² + (y - 3)² =25
(x )² + (y - 3)² =25

Yummy Cookies just opened a brand new cookie bakery, ans sales are increasing every month! In January, the baker made 14 carrot cake cookies. In February, the baker doubled the January order, took 5 cookies home to his family, and sold the rest. If the baker continues to double the full amount and then bring 5 cookies home to his family, how many cookies will the baker sell in March and April?
Answer:
March he sells 51. April he sells 107
Step-by-step explanation:
In jan he made 14 so we double that for feb and have 28.
From that 28 he takes home 5 so we are left with 23.
Then we double 28 for March to get 56 but he takes 5 home which leaves 51 to be sold and so on.

Answer:
20
Step-by-step explanation:
We can use the Pythagorean Theorem to find this: a² + b² = c²
Following that, c² is always the hypotenuse. All we have to do is plug in the variables and solve:
Step 1: Replace variables
12²+16² = c²
Step 2: Solve
144+256 = c²
c² = 400
√400 = √c²
c = 20
And you get x = 20 as your final answer!

find sin angle NOM
A. 1/4
B. 1/3
C. 3/5
D. 4/5
Answer:
C. 3/5
Step-by-step explanation:
Sin of any angle is = perpendicular/ hypotenuse
In any right angle triangle, with side a and b containing right angles and h having hypotenuse, using Pythagoras theorem
[tex]h^2 = a^2 + b^2[/tex]
___________________________________________
In triangle NOM
ON = 4,
NM = 3
lets find OM
using Pythagoras theorem
[tex]OM^2 = ON^2 + NM^2\\=> OM^2 = 4^2 + 3^2\\=>OM^2 =16 + 9 = 25\\=> \sqrt{OM^2} = \sqrt{25} \\=> OM = 5[/tex]
Thus, OM = 5
sin angle NOM = perpendicular/ hypotenuse = NM/OM = 3/5
sin angle NOM = 3/5

Good luck on your assignment...
Answer:
11.12 cm^2.
Step-by-step explanation:
The area of the shaded part = Area of the semicircle - area of the triangle.
The base of the triangle has length 8 - 1 = 7 cm and it's height is equal to the radius of the semicircle which is 4 cm.
So our shaded area = 1/2 * 3.14 * 4^2 - 1/2 * 7 * 4
= 25.12 - 14
= 11.12 cm^2.

O D. y = -2x - 1
Answer:
C.
Step-by-step explanation:
Parallel lines have the same slope but different y-int. So if our original equation is y = 2x + 1, then the other equation would have to be y = 2x + b, where b ≠ 1. Only answer C. works.
Answer:
The answer is C) y-1=2(x-3)
Step-by-step explanation:
Two equations are parallel if they have the same slope and different y-intercepts. In the answer (c) 2 represents the slope which is also the slope of the original equation. y=2x-5is the equation that you get when you distibute and isolate y.

how does the fact that a parallelogram has rotational symmetry demonstrates that opposite side of a parallelogram are congruent ?
Answer:
See below.
Step-by-step explanation:
It is known that a parallelogram has rotational symmetry, rotated 180 degrees about it's center point. Now by definition a parallelogram is a quadrilateral with two pairs of parallel sides, hence it's name. If you were to take a look at the attachment below, you might see the connection.
Rotational Symmetry will make it so that side AB corresponds to CD, respectively AD and CB. The sides will coincide with one another after a 180 degree rotation, so that AB = CD, and AD = CB. Hence, in the same parallelogram, opposite sides are congruent.

A bridge connecting two cities separated by a lake has a length of 5.651 mi.
Use the table of facts to find the length of the bridge in yards.
Round your answer to the nearest tenth.
Answer:
The equivalent of 5.651 mi is 9945.76 yards
Step-by-step explanation:
Given:
Length of lake = 5.651 mi
Required:
Length of bridge in yards
From table of facts;
1 mile = 1760 yards
This implies that
5.651 miles will be:5.651 * 1760 yards
5.651 * 1760 yards = 9945.76 yards
5.651 * 1760 yards = 9945.8 yards (Aproximated)
Hence, the equivalent of 5.651 mi is 9945.76 yards
A planet has a circular orbit around a star. It is a distance of 74,000,000 km from the centre of the star. It orbits at an average speed of 38,000 km/h. How many Earth days does it take the planet to orbit the star? Give your answer to 2 sf.
Answer:
81.14 Earth days.
Step-by-step explanation:
Step 1
The formula to solve this question is given as
Speed = Distance / Time
In the question, we are given the following values
Distance of the planet = 74,000,000 km
Average Speed of the planet = 38,000 km/h.
Average Speed = Distance / Time
38,000 km/h = 74,000,000 km/ Time
Cross Multiply
38,000 km/h × Time = 74,000,000 km
Divide both sides by 38,000 km/h
Time(hours) = 74,000,000 km /38,000 km/h
Time(hours) = 1947.3684211 hours
This means the circular orbit of the planet around the star takes 1947.3684211 hours.
Step 2
In the question, we were asked to find how many Earth days it takes.
Hence, it is known that
24 hours = 1 (Earth) day
1947.3684211 hours = x days
We would cross Multiply
24 hours × x days = 1947.3684211 hours.
Divide both sides by 24 hours
x days = 1947.3684211 hours ÷ 24 hours
x days = 81.140350879 Earth days.
Therefore, the number of Earth days it takes the planet to orbit the star to 2 significant figures =
81.14 Earth days.
