Answer:
You spent $14.5
Step-by-step explanation:
You just add tgem ad yeah
Answer:
Step-by-step explanation:
barrier = parameter, so we add all the sides:
8+3+3+5+5 = 24
24*1.75 = $42.
THEN, we need the area to solve for the mulch.
I would split it up into two parts so the rectangle and then the triangle.
First, 8*3 is 24
now we divide this by four because one bag covers four square feet
so, 6 bags (24/4=6) which is $36 (6*$6).
_______________
Now, the triangle, which a = (hb*b)/2
12 divided by four again so 3
3 * 6 = $18.
Now we add ALL costs up to get
42+36+18 = $96 total for the entire project.

Identify the key features of the parabola, 8(y + 4) = (x + 1)2:
Axis of Symmetry:
Vertex:
Focus:
Directrix:
Answer:
Step-by-step explanation:
8(y+4)=2(x+1)
divide by 8 y+4=1/4x+1/4 subtract 4 y=1/4x - 3 3/4 multiply by 4 y=1/4(x-15)
Answers:
Equation in standard form: [tex]y = \frac{1}{8}(x+1)^{2} -4[/tex]
Axis of Symmetry: x = -1
Vertex: (-1, -4)
Focus: (-1, -2)
Directrix: y = -6
Step-by-step explanation:
First, let's clean up some of the mess with the equation that we have been given in this question and put it in standard form so that we can find the features we've been asked to give.
Our initial equation is: [tex]8(y+4)=(x+1)^{2}[/tex]
In order to put our equation in standard form, we must isolate y, so that it is in terms of y.
First, we need to divide both sides by 8. When we do this, we get [tex]y+4=\frac{(x+1)^{2} }{8}[/tex] or [tex]y+4=\frac{1}{8}(x+1)^{2}[/tex]. Then we need to subtract 4 from both sides to get: [tex]y = \frac{1}{8}(x+1)^{2} -4[/tex].
Now, we can start to find the features of the parabola. Remember, the standard form of equations involving parabolas is [tex]y=a(x-h)+k[/tex] where [tex]a =\frac{1}{4p}[/tex].
The axis of symmetry is at [tex]x=h[/tex], in this case [tex]h=-1[/tex] so the axis of symmetry is [tex]x=-1[/tex].
The vertex is located at [tex](h, k)[/tex]. As we previously stated [tex]h=-1[/tex], but additionally, [tex]k=-4[/tex] making the vertex located at [tex](-1,-4)[/tex].
The focus is located at [tex](h, k+p)[/tex] and the directrix is located at [tex]y=k-p[/tex]. For this, we need to find p which we can find with the equation [tex]a =\frac{1}{4p}[/tex]. Substituting the value of “a” into the equation, we get [tex]\frac{1}{8} = \frac{1}{4p}[/tex]. We can cross-multiply to get the equation [tex]4p=8[/tex]. Dividing by 4 on both sides, we get [tex]p=2[/tex]. Now we can find the focus and directrix.
The focus is located at [tex](-1, [-4+2])[/tex] or [tex](-1,-2)[/tex] and the directrix is represented by the equation [tex]y=(-4-2)[/tex] or [tex]y=-6[/tex].

What are the missing measures for E and J???
Are the triangles similar? Yes or no?
Answer:
No
Step-by-step explanation:
To tell whether two triangles are similar or not, we can compare their side lengths or angle measures
in this case, only angle measure are given so will compare those:
m<F = m<I but this is not enough, we need to compare other angles as well
m<H is not equal to m<G
The sum of interior angles in a triangle is equal to 180
so the measure of angle J
100+55+J = 180
J = 25
The measure of angle E
100+35+E = 180
E = 45
Now, neither of these angles are equal to each other so we can conclude that these triangles are not similar.

What is the system of two equations?A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The first equation is given as:

The equations in the system would have different constant values if the system of equations had no solution.
y=8x+b
Where:
b is a variable that is not equal to 7.
The equation whose standard form is y=ax+b has no solution. Only equation 2 satisfies the generalized form.

Nadia needs one cup of ice cream for every student in her class for their year-end party. the ice cream is only sold in pints. if there are 24 students in her class, how many pints of ice cream will she need? describe how to solve this problem.
Answer:
12 pints
Step-by-step explanation:
There are 24 students & each one gets 1 cup, so you will need 24 cups total. There are 2 cups in a pint. You divided the 24 cups you need by 2 cups in a pint to get the answer of 12 pints.
You can double check: 12 pints converted to cups (2 cups in a pint) is 12 x2 = 24 cups

write a function for the line that includes the points (4,-5) and (8,-7)
Answer:
[tex]y = -\frac{1}{2} x - 3[/tex]
Step-by-step explanation:
Answer:
f(x) = -1/2x - 3.
Step-by-step explanation:
The slope of the line = ((-7 - -5) / (8 - 4)
= -2/4
= -1/2.
y - y1 = m(x - x1)
m = -1/2, x1 = 8 and y = -7 so:
y - (-7) = -1/2(x - 8)
y + 7 = -1/2x + 4
y = -1/2x - 3.

A scientist wants to estimate the number of lions living in a region.
On Thursday, he locates and tags some lions. I
On Friday he returns and locates 10 less lions than he had on Thursday.
He notices that 4 of the lions are tagged
The scientist works out an estimate for the total number of lions living in the
region.
He notices that the number of lions that he had caught on Thursday, was a
fifth of the total number of lions.
How many lions live in the region?
The number of the lions that live in the region investigated by the considered scientist is 80.
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
For this case, we're specified that:
He locates and tags lions on ThursdayOn friday, he locates 10 less lions than he had on Friday.He notices (on friday) that 4 of the lions are tagged.The number of lions caught on thursday was a fifth of the total number of lions.Let we take:
x = number of lions the scientist located and tagged on thursday.
Then, we get:
x - 10 = number of lions the scientist located (and assumingly found that they're tagged) on friday,
4 = number of lions he found tagged on friday.
That means, x -10 is same number as 4
or, we get:
[tex]x - 10 = 4\\\text{Adding 10 on both the sides}\\\\x = 14[/tex]
That means, on thursday, the scientist located and tagged 14 lions.
Now, suppose that the region had 'y' number of lions,
Then, as per the data in the question,
one-fifth of y = number of lions located by scientist on thursday
or, we get:
[tex]\dfrac{y}{5} = x\\\\\dfrac{y}{5} = 14\\\\\text{Multiplying 5 on both the sides}\\\\y = 80[/tex]
Thus, the number of lions that live in the region considered is 80

Alexandra and Stephanie are sisters, and they're saving their money to buy a used car. Together they have more than $2,500, and Alexandra has $700 more than Stephanie. How much money does Stephanie have?
Answer:
Stephanie has more than $900
Step-by-step explanation:
Represent the unknowns: a for Alexandra and s for Stephanie.
Then a + s > $2,500, and a = s + $700.
Substituting the latter into the former equation, we get:
(s + $700) + s > $2,500, or
2s > $1800
Then s > $900; Stephanie has more than $900.

A percentage is a way to describe a part of a whole. The most improbable simulation for this coin is heads are 9.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
The most improbable simulation for this coin for heads is the frequency of heads coming up out of 20 which is far from the estimated frequency. Since out of these 20 times 75% of the times the head will come up. Therefore, the number of times the head will come up can be written as,
