Answer:
10.75
-5/4
2 7/24
Step-by-step explanation:
1.)
__+-3.5=7.25
Let missing number = x
x - 3.5 = 7.25
x = 7.25 +3.5
x = 10.75
2.)
-3/4-__=1/2
Let missing number = x
-3/4 - x = 1/2
-3/4 - 1/2 = x
(-3 - 2) / 4 = x
-5/4 = x
3.)
-2 3/8-(-4 2/3) = x
-2 3/8 + 4 2/3 = x
-19/8 + 14/3 = x
(-57 + 112) / 24 = x
55 / 24 = x
2 7/24
Mr. Perrins’s class sold packs of peanut butter cookies for $2.35 each and Mr. Woods’s class sold bottles of milk for $1.34 each. Together, the classes sold 73 items and earned $141.25 for their school. Write and solve a system of equations that model the problem. Show all your work. (a) Which class earned more money? (b) How much more money did that class earn?
Answer:
1. Solution = (4,3) and they intersect.
2. Solution = Infinite, this means that the lines overlap each other constantly.
3. Equations = x + y=73 and 2.35x + 1.34y = 141.25

Answer:
53°
Step-by-step explanation:
Let m∠BCA = 'x'
Because it states that quadrilateral ABCD is a rectangle (sorry, forgot to say that in my image), that means that angles ∠ABC, ∠BCD, ∠CDA and ∠DAB are all right angles. That also means that all those angles are 90°.
Since ∠ACD is a portion of ∠BCD, (37° is a portion of 90°), and we're looking for the complement of ∠ACD, all we have to do is subtract 37° from 90°.
90 - 37 = 53
Hence, the answer is 53°
Find x and y ( please explain )
Answer:

Camila owns a car worth $5,900 and owes $2,800 on the car loan. She has $1,600 in her bank account and $5,210 in a savings account. She has a balance of $1,400 on her credit card. What is her net worth?
Answer:
[tex]Net\ Worth=11310[/tex]
Step-by-step explanation:
From the question we are told that:
Car worth [tex]C=5900\$[/tex]
Car Loan[tex]L=2800\$[/tex]
Bank account [tex]B= 1600\%[/tex]
Savings account [tex]S=5210\&[/tex]
Credit card [tex]CC=1400\%[/tex]
Generally Net worth is the value of the assets a person or corporation owns, minus the liabilities they owe.
Therefore
[tex]Net\ Worth=Asset-Liability\\\\Net\ Worth=Car worth+Bank account+Savings account +Credit card-Car Loan\\\\Net\ Worth=5900+1600+5210+1400-2800[/tex]
[tex]Net\ Worth=11310[/tex]

Which equation represents the parent function translated to the right 4 units and stretched by a factor of 5?
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete. So, I will solve a general solution, instead.
Let (x,y) be the parent function
First transformation: 4 unit right translation
The rule to this is: [tex](x,y) \to (x + b,y)[/tex]
Where b is the units of translation
i.e. [tex]b = 4[/tex]
So, we have;
[tex](x,y) \to (x + 4,y)[/tex]
Second transformation: Stretch by a factor of 5
The rule to this is: [tex](x,y) \to (x ,ay)[/tex]
Where a is the units of translation
i.e. [tex]a = 5[/tex]
So, we have;
[tex](x + 4,y) \to (x+4,5y)[/tex]
Hence, the transformation from the parent function to the new function is:
[tex](x + 4,y) \to (x+4,5y)[/tex]

i need help with this please^^
Step-by-step explanation:
here's your solution
=> angle 3 and angle 8 are interior angles
we know that sum of both angle is 180°
=> angle 3 + angle 8 = 180°
=> angle 3 + 129° = 180°
=> angle 3 = 180° - 129°
=> angle 3 = 51°
now , angle 3 and angle 1 are vertical angle
hence both angle are equal
=> angle 1 = 51°

Find the circumference of the circle below. Hint: Use 3.14 for π.)
Use numbers only in your answer.
The circumference is
yd.
Answer:
[tex]\boxed {\boxed {\sf 163.28 \ yards}}[/tex]
Step-by-step explanation:
The circumference of a circle is the distance around the circle, or the perimeter. It is the product of pi and the diameter.
[tex]c= \pi \times d[/tex]
The diameter is the distance from one side to the other through the center. If we look at the circle given, we see the diameter must be 52 yards.
d= 52 ydAlso, remember we are using 3.14 for pi.
[tex]\pi[/tex]= 3.14Substitute these values into the formula.
[tex]c= 3.14 * 52 \ yd[/tex]
Multiply.
[tex]c=163.28 \ yd[/tex]
The circumference of the circle is 163.28 yards.
Answer:
[tex]\large\fbox{\purple{\underline{Circumference of circle is 163.28 yards}}}[/tex]
Step-by-step explanation:
In the question we have given
Diameter of circle is 52 yards
And Value of π = 3.14
We know that
Circumference of circle = π × diamter
putting the values
Circumference = 3.14 × 52 yards
by mutiplying we get,
Circumference of circle = 163.28 yards
Therefore, Circumference of circle is 163.28 yards

What is the measure of ∡U in the figure shown? ∘
Answer:
∠ U = 70°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
120° is an exterior angle of the circle , then
∠ U + 50° = 120° ( subtract 50° from both sides )
∠ U = 70°

Can someone plz help me
Answer:
24°
Step-by-step explanation:
Supplementary angles: angles that add up to 180°
Thus, ∠A + ∠B = 180°
=> (x + 6)° + (7x + 30)° = 180°
=> 8x + 36 = 180
=> 8x = 180 - 36
=> 8x = 144
=> x = 18
∠A = (18 + 6)° = 24°

1. Which of the following is the equation of a circle with center (a, −b) and radius r?
A. (x−a)2+(y+b)2=r2
B. (x+a)2+(y−b)2=r2
C. (x+a)2+(y−b)2=r
D. (x−a)2+(y+b)2=r
2. A given circle has the equation x2+y2−4x−2y+4=1. What is the center of the circle?
A. (1, 2)
B. (−2, −1)
C. (−1, −2)
D. (2, 1)
Answer:
1) A
2) D
Step-by-step explanation:
1) The equation of a circle is (x-h)²+(y-k)²=r² where (h,k) is the center and "r" is the radius of the circle. With a center of (a,-b) the equation of the circle is (x-a)²+(y+b)²=r² making A the correct answer.
2) Convert from general form into standard form:
Given: x²+y²-4x-2y+4=1
Rearrange: x²-4x+4+y²-2y=1
Set right side equal to 0: x²-4x+4+y²-2y-1=0
Complete the square: x²-4x+4+y²-2y-1+2=0+2
Evaluate: x²-4x+4+y²-2y+1=2
Condense: (x-2)²+(y-1)²=2
Therefore, the center of the circle is D) (2,1)
What is the volume of a sphere with a radius of 2.6 ft, rounded to the nearest tenth of
a cubic foot?
Answer:73.6fr^3
Step-by-step explanation:
The volume of the sphere is [tex]73.57ft^3[/tex].
What is the volume of sphere?
The volume of sphere is the amount of space occupied, within the sphere. The sphere is defined as the three-dimensional round solid figure in which every point on its surface is equidistant from its centre.
[tex]V=\frac{4}{3}\pi r^3[/tex]
here [tex]r[/tex] is the radius and it is [tex]r=2.6ft[/tex]
So,
[tex]V=\frac{4}{3}\pi r^3\\\\V=\frac{4}{3}(3.14)(2.6)^3\\\\V=\frac{4}{3}(3.14)(17.576)\\\\V=\frac{4(55.18)}{3}\\\\V=\frac{220.72}{3}\\\\V=73.57ft^3[/tex]

Three fish are swimming at three different elevations: -1 foot, -5 feet, and - 8 feet. Which fish is closest to the surface of the water? How do you know?
Answer:
Fish with -1 foot
Step-by-step explanation:
- = under
+= above
If you set your water level to 0 then:
-1 +0 = -1 so the fish is 1 foot under the water level
-5 +0 = -5 do the fish is 5 foot under the water
And the last fish either jumped super high or it was hanging on a fishing line becouse it was 8 feet above the water level
So the fish that was the closes to the water level was the fish with -1
