Answer:
x = -6,6
Step-by-step explanation:
h(x)=−5x^2 +180
Assuming you want to find the zero's
0 =−5x 2 +180
Subtract 180 from each side
0-180=−5x^2 +180-180
-180 = -5x^2
Divide each side by -5
-180/-5 = -5x^2/-5
36 = x^2
Take the square root of each side
±sqrt(36) = sqrt(x^2)
±6 = x
x = -6,6
Answer:
-6, 6
Step-by-step explanation:
h(x) = -5x² + 180
-5x² + 180 = 0
x² = 36
x = -6, 6

A 1/2 Kilogram of flour is packed equally into 8 bags. How much flour is in each bag?
Answer:
1/16
Step-by-step explanation:
So if you want to divide an amount equally, you divide the numbers. In this scenario, what you would do is this:
1/2 needs to be split 8 times
(1/2)/8
If you have something like this where the numerator is a fraction, then you multiply 2x8. that gives you 16, so now you add the 1 on top and you get 1/16.

Answer:
[tex]214in^{2}[/tex]
Step-by-step explanation:
First we find the area of the regular hexagon.
Area = 4√3*24
Area ≈ [tex]166in^{2}[/tex]
Now we find the area of the other shaded region, which is a parallelogram.
Area = bh
The base of the parallelogram is congruent to one of the sides of the regular hexagon, which means the base is 8 inches.
To find the height, we have to look at the right triangle next to the parallelogram. As we can see, the long leg of the right angle is perpendicular to the base of the parallelogram, and since the height of a parallelogram is perpendicular to its base, we find out that the height of the parallelogram is 6 inches.
Now we find the area.
Area = 6*8
Area = [tex]48in^{2}[/tex]
Now we add the both areas.
[tex]166 in^{2}+48 in^{2}=214 in^{2}[/tex]
The area of the composite figure is ≈ [tex]214 in^{2}[/tex]
Carly works at a local bakery. She needs 8 cups of flour to make a cake and 4 cups of flour to make 16 cupcakes. It she started the
day with 18 pounds of flour, and one pound of flour equals four cups of flour, how much flour will Carly have left after she makes 4
cakes and 32 cupcakes?
OA. 65 cups
OB. 64 cups
OC. 32 cups
OD. 24 cups
Answer:
All things said, Carly needs 32 cups for compose her bakery items.
Step-by-step explanation:
First, let' see how much flower in all would need to be used for the following delicacies, knowing she started with 72 cups of flower.
4 x 8 = 32 cups for the cake
4:16 = for only 16 cupcakes, so double it 8:32... 8 cups of flour.
Thus, 8+32= 40 & 72-40= 32
All things said, Carly needs 32 cups for compose her bakery items.

» A florist makes bouquets that include 50 white flowers
and 7 red flowers. If the florist orders 1,050 white
flowers and 140 red flowers, there will be leftover
flowers. How can the florist adjust the order so there
are no leftover flowers?
Answer:
The florist needs to order me 7 more red flowers then there will be enough for 21 bouquets, with no flowers left over.
Step-by-step explanation:
If she had given back 50 of the others then the florist would classify that as left over stock, so she would need to order and ask for 7 more.
1050 / 50 = 21
140/7 = 20

Answer:
Y-intercept or b = 2.5
X-intercept = 3.5
Step-by-step explanation:
The y-intercept is where the graph intersects on the y-axis, where x=0.
Thus, the y-intercept or b = 2.5.
The x-intercept is where the graph intersects on the x-axis, where y=0.
Thus, the x-intercept = 3.5.

Door 3 diagonal 3√10 feet
Step-by-step explanation:
The diagonal of a rectangle is the hypotenuse of a right triangle whose legs are the side lengths of the rectangle. That is, the diagonal of a 9 ft by 3 ft rectangle will have length ...
d = √(9² +3²) = √90 = 3√10
Any "9 ft by 3 ft" figure that has a diagonal different from this is not a rectangle. To fit the rectangular opening, we want a rectangular door—one with a diagonal of 3√10 feet.

Combine like terms to create an equivalent expression.
1.3b+7.8-3.2b1.3b+7.8−3.2b
Answer:
-1.9b + 7.8
Step-by-step explanation:
The equivalent expression for the given expression is -1.9b+7.8.
The given expression is 1.3b+7.8-3.2b.
We need to combine like terms to create an equivalent expression.
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
Now, combine like terms:
The like terms are defined as the terms that contain the same variable which is raised to the same power. In algebraic terms, only the numerical coefficients can vary.
Then, 1.3b+7.8-3.2b=(1.3b-3.2b)+7.8
=-1.9b+7.8
Therefore, the equivalent expression for the given expression is -1.9b+7.8.

Factor this expression completely. −3x − 12 A) 3(x + 4) B) 3(x − 4) C) −3(x + 4) D) −3(x − 4)
Answer:
C
Step-by-step explanation:
Look at the coefficients in the expression: -3 and 12. The largest number that divides them both is 3. That means you can factor out either a 3 or a negative 3. Try 3.
3(-x - 4) is not on the list of answers. Also, it's unusual to factor out a value that leaves a negative coefficient on x.
Try factoring out -3.
-3(x + 4) is answer choice C.

Because this is a multiple-choice question without a "non of these" option, you can solve the problem by expanding--multiplying out--the answers!

Write the equation of the circle.
A circle with a diameter having endpoints at (0, 1) and (6,-4)
Answer:
(x - 3)² + (y + 1.5)² = 15.25
Step-by-step explanation:
Centre: midpoint of the diameter
(h,k) = (0+6)/2, (1-4)/2
= (3, -3/2)
Radius = ½(diameter)
Diameter = sqrt(6² + (-4-1)²)
sqrt(61)
Radius = sqrt(61)/2
Equation:
(x - h)² + (y - k)² = r²
(x - 3)² + (y + 1.5)² = 15.25
dianne runs around a circular track that has a radius of 55 feet. after running three quarters of the distance around the track, how far has she run?
Answer:
She has run 259.18m
Step-by-step explanation:
Since Dianne is running around the circular track, she is running around the perimeter of the circle.
Now, we know that the perimeter of a circle is given by;P = 2πr
Thus the perimeter of the track = total distance that the man travels = 2 x π x 55 = 345.575 meters
Now,since she has run 3/4 of the distance, thus, she has run;
(3/4) x 345.575 = 259.18m
Answer:
She has run 259.18m
Step-by-step explanation:
Since Dianne is running around the circular track, she is running around the perimeter of the circle.
Now, we know that the perimeter of a circle is given by; P = 2πr
Thus the perimeter of the track = total distance that the man travels = 2 x π x 55 = 345.575 meters

The primary reason for the construction of a network of railroads in Europe during the 19th century was to provide a more efficient means to transport goods, promoting trade and boosting economical growth, although it also facilitated the movement of armies and people.
Explanation:The best explanation for the construction of a network of railroads linking Europe together during the nineteenth century is that the Rail service provided more efficient means to transport goods across Europe. This period, known as the Railway Age, saw exponential growth in the expansion of railroads because they created an efficient and faster way for countries to trade goods, thus boosting their economies.
Not only did the burgeoning rail network provide a means for rapid movement of goods, but it also facilitated the movement of people, creating job opportunities and promoting cultural exchange.
While it is true that rail service allowed armies to move quickly and people to visit families across the continent, the primary impetus for the expansion of the rail network was economic – facilitating trade and industry.

start fraction, x, squared, divided by, y, start superscript, 1, end superscript, end fraction when x=10x=10x, equals, 10 and y=5y=5y, equals, 5?
Answer:
20???
Step-by-step explanation:
The value of the expression x^2/y when x equals 10 and y equals 5, is computed by squaring x, which equals 100 in this instance and then dividing the result by y. Therefore, the result is 100 divided by 5, which equals 20.
Explanation:The subject of this question is determining the value of the expression x^2/y, a topic in Mathematics, specifically in Algebra. In this case, we are given that x = 10 and y = 5. The expression presented in the question is x^2/y. This mathematical expression states that x should be squared (i.e., x times x, which equals 10 times 10 in this instance) and the result should then be divided by y. Therefore, the solution can be found as follows:
First, square the value of x: 10*10 = 100.Then, divide this result by the value of y: 100/5 = 20.So, the value of x^2/y when x = 10 and y = 5 is 20.
