Answer:
C. -7f > -9 because -7f is warmer than -9f
Step-by-step explanation:
Process of Elimination
You can rule out B and D because the answer contradicts itself.
Previous Knowledge
We know -7f is warmer than -9f because its closer to 0 so we can rule out A
Therefore through the process of elimination you can conclude the answer is C
4x - y = -7
-8x + 4y = 12
Elimination
Answer:
(x,y)=(-2,-1)
Step-by-step explanation:
4x - y = -7: 8x-2y=-14
8x-2y=-14
-8x + 4y = 12
add these two:
2y=-2
y=-1
plug in the y:
-8x-4=12
-8x=16
x=-2
Two people share $52.20 in the ratio 4:5. How much does each person receive?
Answer:
$23.20 and $29
Step-by-step explanation:
We can set up a simple equation to solve this problem.
4x + 5x = 52.2
9x = 52.2
x = 5.8
To find out how much each person received, we multiply 5.8 with the ratio numbers 4 and 5. That gives us $23.20 and $29, respectively.

Answer:
4) d = 60; e = 90
5) f = 30
6) h = 120
Step-by-step explanation:
4)
d + d + d = 180
3d = 180
d = 60
e + e + e + e = 360
4e = 360
e = 90
5)
70 + (180 - 100) + f = 180
70 + 80 + f = 180
f = 30
6)
45 + 75 + (180 - h) = 180
300 - h = 180
-h = -120
h = 120
HELP! Determine the equation of the exponential function with a common ratio of 2, a horizontal asymptote at y = 4, and passing through the point (2, 10).
Answer:
[tex]\bold{y=1.5\times 2^x+4}[/tex]
Step-by-step explanation:
Equation for an exponential function is given as following:
[tex]y=ab^x+c[/tex]
Where b is the common ratio and
c is the horizontal asymptote (y value)
a is the coefficient of exponential term of [tex]x[/tex]
[tex](x,y)[/tex] are the points on the function.
Here, we are given that:
Common ratio, b = 2
Horizontal asymptote at y, c = 4
So, the equation becomes (let us put the values of b and c):
[tex]y=a\times 2^x+4[/tex]
We need the value of a. Let us put value of (x,y) as (2,10).
[tex]10=a\times 2^2+4\\\Rightarrow a\times 4 =10-4 =6\\\Rightarrow a =\dfrac{6}{4} =\bold{1.5}[/tex]
So, the final equation of the exponential function is:
[tex]\bold{y=1.5\times 2^x+4}[/tex]

The number of fish (f) in a fish tank increases when the number of algae blooms (a) decreases. Write the correct equation for this scenario, and solve for the number of fish when there are 4 algae blooms. Algae Blooms Fish 10 10 25 4
Answer:
f = -2/5a +1412.4 ≈ 12 fish for 4 algae bloomsStep-by-step explanation:
The 2-point form of the equation for a line is useful when you are given two points to work with:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
The independent variable (x) is apparently "algae blooms" and is to be represented by "a". The dependent variable (y) is "number of fish" and is to be represented by "f". So, we have ...
f = (4 -10)/(25 -10)(a -10) +10
f = -6/15(a -10) +10
f = -2/5a +14 . . . an equation for the scenario
Four a=4, the fish population is predicted to be ...
f = -2/5(4) +14 = 12.4
There will be about 12 fish when there are 4 algae blooms.
*PLEASE ANSWER THANK YOU* A toy rocket is a composite of a cylindrical body with a cone for a nose. Find the volume of the rocket if the radius of the base is 1.25 inches, the height of the tip is 3 inches, and the height of the entire rocket is 15 inches. a.) 176.6 in3 b.) 56.3 in3 c.) 58.9 in3 d.) 63.8 in3
Answer:
Volume of toy = 63.8 in² (Approx)
Step-by-step explanation:
Given:
Height of cone (h) = 3 in
Height of cylinder (H) = 15 - 3 = 12 in
Radius (r) = 1.25
Find:
Volume of toy
Computation:
Volume of cylinder = πr²H
Volume of cylinder = (22/7)(1.25)(1.25)(12)
Volume of cylinder = 58.92 in²
Volume of cone = (1/3)πr²h
Volume of cone = (1/3)(22/7)(1.25)(1.25)(3)
Volume of cone = 4.91 in²
Volume of toy = Volume of cylinder + Volume of cone
Volume of toy = 58.92 in² + 4.91 in²
Volume of toy = 63.8 in² (Approx)
What are the major arcs of o0 that contain point B?
Answer:
Option (C)
Step-by-step explanation:
By the definition of a major arc - any arc of a circle which measures more than 180° is the major arc.
In the given circle, AC and BD are the two chords.
And arcs measuring more than 180° are,
[tex](\widehat{BCA}, \widehat{CDB}, \widehat{ABD},\widehat{DAC},\widehat{DBC},\widehat{ACD})[/tex]
Therefore, the arcs given in Option (C) will be the major arcs of the circle O.
Option (C) will be the correct option.

2) A quadrilateral is a four sided two-dimensional shape
3) A line segment is a line portion between two end points
4) A ray is a line with one end point that extends to infinity in a direction
5) A line is a one dimensional straight geometric figure that extends to infinity in both directions.
Hank and Lynn are both paying off car loans. • Hank paid $2,000 upfront when he bought his car, and he pays $200 each month. • Lynn did not pay any money upfront when she bought her car, and she pays $275 each month. Is the relationship between the number of months and the total amount paid proportionally for both Hank's and Lynn's loans?
Answer:
the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.
Step-by-step explanation:
The relationship between the number of months and the total cost paid proportionally is shown below:-
Both Hank and Lynn pay off car loans.
When Hank bought his car, he paid $2,000 in advance, and he needs to pay $200 each month.
Thus, forward to x months the total cost paid (C(h)) is
C(h) = 2000 + 200x ... (i)
So, that relationship is proportional, but not proportional directly.
When Lynn purchased her vehicle, she didn't pay any cash immediately front and she needs to pay $275 every month.
So, after x months the total amount paid (C(l)) is
C(l) = 275x ..... (ii)
This is, therefore, a direct proportionality that is also proportional.
Furthermore the linkage between both the number of months and the amount charged is proportional to both loans from Hank and Lynn.
Answer: The relationship between the number of months and the total amount paid for both Hank and Lynn's loans is proportional.

soup ordinarily priced at 2 cans for 33 cents may be purchased in lots of one dozen for 1.74.What is the savings per can when it s purchased this way?
Answer:
2 cents per can
Step-by-step explanation:
The price per can when you buy two cans is:
0.33/2 = $0.165, or 16.5 cents per can
When purchased in a lot of one dozen, the price per can is:
1.74/12 = $0.145, or 14.5 cents per can
So the savings per can when you buy a dozen is:
0.165 - 0.145 = $0.02, or 2 cents per can
Answer:
You save 2 cents per can. $0.02
Step-by-step explanation:
Since one dozen = 12, you need to figure out what 12 can would regularly cost. So multiply the 33 cents by 6 (since 2 x 6 =12).
33 x 6 = 198
Add the decimal and it's $1.98. now subtract $1.74 from $1.98.
1.98 - 1.74 = 0.24
This is the saving for 12 cans, but you want the savings for one can. So you would divide 0.24 by 12.
0.24/12 = 0.02
So you save 2 cents per can.
Renee wants to put a fence around her
square garden that has an area of
6,500 square feet. Determine the
perimeter of the garden to the nearest
tenth of a foot.
Answer:
320 "if rounded"
Step-by-step explanation: you find out what number times itself equals 6500 which is 80.623 "rounded to 80" then you add up all the sides "80+80+80+80" or "8x4" which would be 320 but you have to do nearest tenth so your answer would be 322.4.

Which is one piece of information that "9" gives about
an atom of fluorine?
The atomic mass is different than the atomic number,
and the number of neutrons is the difference between
the atomic mass and the atomic number.
O the atomic number
O the atomic mass
o the hiass of protons
o the number of neutrons
Answer: The information in that "9" is the atomic number of the atom.
Step-by-step explanation:
For an atom of fluorine we have:
A = atomic weight = 18.99 amu.
Z = atomic number = 9.
(A - Z) = number of netrons = 10.
Then the "9" in the information of the atom of fluorine gives information about the atomic number.
Answer:
the atomic number

What information do you need to complete a translation?
Answer:
1. The coordinates of the image you want to transform
2. The change in y
3. The change in x
Step-by-step explanation:
If we transform an image, we are moving it around the coordinate plane.
In order to transform, we need the original coordinates of the image so that we know where to start.
We also need to know the change in y because when we transform a shape it can go up and down.
We also need to know the change in x because when we transform a shape it can go left and right.
Hope this helped!
