A cat eats 1/2 cup of food a day. Which equation represents
how much food it eats over time?
Y= 1/2x
Y=-2x
Y= 2x
Y=-1/2x
Answer:
Y = 1/2x
Step-by-step explanation:
x is the amount of cups the cat eats so if it eats 1/2 cup of food each da it would be 1/2x

Kara runs two laps around a track. It takes her 51.495 seconds to complete her first lap and between 53 and 54 seconds to complete her second lap. Her total time for both laps is a whole number of seconds. How long, in seconds, does Kara take to complete her second lap?
Answer:
I believe the answer is 53.505 seconds.
Answer:
53/505
Step-by-step explanation:
Remark
You know that the time must be 53. something for the second lap. If the total of the first and second lap is a whole number, then all you need do is add something to 0.495 to get a whole number.
Method
What you have to do is add 1 - 0.495 to get the decimal to add to 53.
1 - 0.495 = 0.505 which will give you a whole number.
Answer
The answer then is 53.505
Check

Answer:
C. 1796.08 [tex]in^2[/tex]
Step-by-step explanation:
Area of circle is [tex]\pi r^2[/tex], r is the radius
remember radius is from the center to the edge, so it is half the diameter
now we need to find the area of the large circle (table) minus the small circle (hole)
the radius of the large circle is 48/2 which is 24
the area is [tex]\pi 24^2[/tex] replacing r in the formula with 24, the radius. Using 3.14 as pi, the answer is 1808.64
the radius of the small circle is 4/2 which is 2
the area is [tex]\pi 2^2[/tex] so the calculated value would be 12.56
now subtract the area of the hole (small circle) from the area of the table (large circle)
1808.64 - 12.56 = 1796.08
and there's your answer
hope that helps, lmk if it doesn't :)
Answer:
Step-by-step explanation:
r₁ = radius of tabletop = 24 in
r₂ = radius of hole = 2 in
area of hole = πr₂² = 4π in²
area of tabletop = πr₁² - πr₂² = 576π - 4π = 572π ≈ 1796.08 in²

Heya!
[tex] \star \underline{ \underline{ \large{ \text { {Question}}}}} : [/tex] In the given figure , PQRS is a rhombus and SRM is an equilateral triangle. If SN [tex] \perp[/tex] RM and [tex] \angle[/tex] PRS = 55° , find the size of [tex] \angle[/tex] QSN.
~Thanks in advance!
Answer:
[tex]m\angle QSN=65^\circ[/tex]
Step-by-step explanation:
In the given figure, PQRS is a rhombus and SRM is an equilateral triangle.
We are also given that SN⊥RM and that ∠PRS = 55°.
And we want to find the measure of ∠QSN.
Remember that since PQRS is a rhombus, the angles formed by its diagonals are right angles. Let the intersection point of the diagonals be K. Therefore:
[tex]m\angle RKS=90^\circ[/tex]
Now, RKS is also a triangle. The interior angles of all triangles must be 180. Thus:
[tex]m\angle RKS+m\angle KSR+m\angle SRK=180[/tex]
Substitute in known values:
[tex]90+55+m\angle KSR=180[/tex]
Solve for ∠KSR:
[tex]m\angle KSR+145=180\Rightarrow m\angle KSR=35^\circ[/tex]
Since SRM is an equilateral triangle, this means that:
[tex]m\angle SRM=m\angle RMS=m\angle MSR=60^\circ[/tex]
Note that RNS is also a triangle. Therefore:
[tex]m\angle SRM+m\angle RNS+m\angle NSR=180[/tex]
Substitute in known values:
[tex]60+90+m\angle NSR=180[/tex]
So:
[tex]m\angle NSR+150=180\Rightarrow m\angle NSR=30^\circ[/tex]
∠QSN is the addition of the two angles:
[tex]m\angle QSN=m\angle KSR+m\angle NSR[/tex]
Therefore:
[tex]m\angle QSN=35+30=65^\circ[/tex]
Answer:
[tex] \displaystyle\sf \angle \: QSN = {65}^{ \circ} [/tex]
Step-by-step explanation:
we are given a rombus and an equilateral triangle and [tex]\angle PRS[/tex]
said to figure out [tex]\angle QSN[/tex]
we know that
every angle of an equilateral triangle is 60°
so
[tex]\displaystyle \angle SRM[/tex] should be 60°
the point where two diagonals of triangle intercept be x
recall the diagonals of a rhombus intercept each other at right angles
so [tex]\displaystyle \angle SXR [/tex] should be 90°
we are also given SN [tex] \displaystyle \perp[/tex] RM
so [tex]\displaystyle\angle RNS[/tex] should be 90°
notice that SXRN is a quadrilateral
so the sum of its interior angles is 360°
according to the question
[tex] \displaystyle\sf\angle RNS + \angle SXR + \angle PRM + \angle \: QSN = 360[/tex]
substitute the value of [tex]\angle RNS,\angle SXR\: and \: \angle PRM[/tex]
[tex] \displaystyle\sf {90}^{ \circ} + {90}^{ \circ} + {115}^{ \circ} + \angle \: QSN = {360}^{ \circ} [/tex]
simplify addition:
[tex] \displaystyle\sf {295}^{ \circ} + \angle \: QSN = {360}^{ \circ} [/tex]
cancel 295 from both sides:
[tex] \displaystyle\sf {295}^{ \circ} - {295}^{ \circ} + \angle \: QSN = {360}^{ \circ} - {295}^{ \circ} [/tex]
hence
[tex] \displaystyle\sf \angle \: QSN = {65}^{ \circ} [/tex]

Sarah can wrap 44 presents in 4 hours. How many present can she wrap in 7 hours.
Answer:
77
Step-by-step explanation:
44÷4=11 she wraps 11 presents in one hour so 11×7=77 so she wraps 77 presentS in 7 hours
Answer:
77
Step-by-step explanation:
First we have to find the unit rate. So we divde 44 by 4 and get 11. To find how any presents she can wrap in 7 hours, we multiply 7 by 11 to get 77. So, she can wrap 77 presents in 7 hours.
