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

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]

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

Answer: [tex]\sqrt{85}[/tex] or 9.2
Step-by-step explanation:
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)
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]

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

GEOMETRY HELP PLEASE!! WILL MARK BRAINLEIST!
6
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°
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°
45% of Ms. Stacey's students will go on a field trip to the museum. If 90 of Ms. Stacey's students went to the museum field trip how many students does she have overall? A. 40.5 B. 50 C. 200
Answer:
c
Step-by-step explanation:
Number of students = number of students that went to the museum / percentage of students that went to the museum
90 / 0.45 = 200 students
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]
Hence, the volume of the sphere is [tex]73.57ft^3[/tex].

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°

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°
