Step-by-step explanation:
4 3/7 - 5/7 = 3 5/7
We can change the equation to a improper fraction first.
4 3/7 = 4*7+3 = 31/7
31-5 = 26
Therefore the answer is 26/7.
simplify
The answer is equal to 26/7, or 21/7 + 5/7
Which is 3 5/7
Sorry but you did it wrong...
First you gonna make 4[tex]\frac{3}{7}[/tex] become 3[tex]\frac{10}{7}[/tex] ( 4 -> 3 [tex]\frac{7}{7}[/tex] - *you need to make it become the same denominator)
Lets do it: 3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = ...
Because in [tex]\frac{5}{7}[/tex] doesn't have a whole number so you will still keep 3
3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = 3.....
Next, you gonna subtract [tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = [tex]\frac{10-5}{7}[/tex] = [tex]\frac{5}{7}[/tex]
3[tex]\frac{10}{7}[/tex] - [tex]\frac{5}{7}[/tex] = 3[tex]\frac{5}{7}[/tex]
SO the answer for 4[tex]\frac{3}{7}[/tex] - [tex]\frac{5}{7}[/tex] is 3[tex]\frac{5}{7}[/tex]
Hope it helps, Studywell!
Find the volume of this object.
Use 3 for 1.
V=7r2h
Volume of a Cylinder
4 ft.
12 ft
Answer:
504 ft^3
Step-by-step explanation:
Ok, so we have the equation for the cylinder as well as the rectangular prism. Basically we're just going to find the volume of each of them separately and then add them together.
Let's start with the cylinder:
V(cylinder) = pi*r^2*h
pi = 3
d = 4ft
r = d/2 = 4/2 = 2ft
h = 12ft
V(cylinder) = (3)*(2^2)*(12)
V(cylinder) = 3*4*12
V(cylinder) = 144 ft^3
Now the rectangular prism:
V(rectangular prism) = l*w*h
l = 10ft
w = 6ft
h = 6ft
V(rectangular prism) = 10*6*6
V(rectangular prism) = 360 ft^3
Now we can add them together:
V(total) = 360 + 144
V(total) = 504 ft^3
A rectangle has a width of 3 units. The rectangle's length is 5 times its width.
What is the area of the rectangle?
Answer:
Answer= 45 units
Step-by-step explanation:
lengths = 3 units
width = 3x5= 15 units
area= length times width= 3x15= 45 units!

a = 5, b = 4, and c = 2. so 2a= what
Step-by-step explanation:
2a = 10 because a = 5 and 2a means 2 × a which is the same as 2 × 5 and this equals 10.

6 (-2g - 1) = (13g + 2)
what is g?
Answer: g = -0.32
Step-by-step explanation:
Given
6 (-2g - 1) = (13g + 2)
Expand parentheses and apply the distributive property
6 · (-2g) - 6 · 1 = 13g + 2
-12g - 6 = 13g + 2
Add 12g on both sides
-12g - 6 + 12g = 13g + 2 + 12g
-6 = 25g + 2
Subtract 2 on both sides
-6 - 2 = 25g + 2 - 2
-8 = 25g
Divide 25 on both sides
-8 / 25= 25g / 25
[tex]\boxed{g=-0.32}[/tex]
Hope this helps!! :)

Find the probability of “landing” in the shaded region of the figures below. Round your answer to the nearest hundredth.
3. Square with side length 40 ft
Answer:
Area of the square:
A = a² = 40² = 1600 ft²Area of the circle:
A = πr² = 3.14*(40/2)² = 1256 ft²Probability of landing in the shaded region:
P = 1256/1600 = 0.785 or 78.5%Answer:
78.5%
Step-by-step explanation:
We can find the area of both shapes then divide to find the probability.
Square area:
40 * 40 = 1600ft²
Circle area with diameter [ 1/4πd² ]:
1/4π(40)²
1/4π(1600)
0.785(1600)
1,256
Now divide both areas to find the probability.
1256/1600 = 0.785
0.785 * 100% = 78.5%
Best of Luck!

Answer:45 ish
Step-by-step explanation:
A fisherman can row upstream at 1 mph and downstream at 4 mph. He started rowing upstream until he got tired and then rowed downstream to his starting point. How far did the fisherman row off the entire trip took 5 hours?
He rowed for 4 miles
it took him 4 hours to get upstream which is 4 miles and since he can do 4 miles per hour down stream it only took him an hour to get back to the starting point which is 5 hours in total.

Prove this
1-tan^2x/1+tan^2x=cos^2x-sin^2x
Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x = [tex]\frac{sinx}{cosx}[/tex]
Consider the left side
[tex]\frac{1-tan^2x}{1+tan^2x}[/tex]
= [tex]\frac{1-\frac{sin^2x}{cos^2x} }{1+\frac{sin^2x}{cos^2x} }[/tex] ( multiply numerator and denominator by cos²x to clear fractions
= [tex]\frac{cos^2x-sin^2x}{cos^2x+sin^2x}[/tex] ← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven

Answer:
6/25
Step-by-step explanation:
.24 = 24/100 = 6/25
Answer:
6/25
Step-by-step explanation:
step 1 The decimal number = 0.24
step 2 Write it as a fraction
0.24/1
step 3 Multiply 100 to both numerator & denominator
(0.24 x 100)/(1 x 100) = 24/100
It can be written as 24% = 24/100 or 24/100
step 4 To simplify 24/100 to its lowest terms, find LCM (Least Common Multiple) for 24 & 100.
4 is the LCM for 24 & 100
step 5 divide numerator & denominator by 4
24/100 = (24 / 4) / (100 / 4)
= 6/25
6/25 is a simplest fraction for the decimal point number 0.24

100 POINTS PLEASE HELP!!!!
Answer:
a. F=1.8c + 32
b. 71.6 degrees Fahrenheit
c. c=(F-32)/1.8
d. 28.3 degrees Celcius
Step-by-step explanation:
a. Given the two data points we can create an equation in slope-intercept form.
The y-intercept is 32
Slope can be found by doing 212-32/100-0 = 180/100 = 1.8
F=1.8c + 32
b. We can use this formula to solve for Fahrenheit
F=1.8(22)+32
F=71.6 degrees
c. Isolate c
F-32=1.8c
(F-32)/1.8=c
d. We can use this formula to solve for Celcius
(83-32)/1.8=c
c= 28.3333333 degrees
We can round that to 28.3 degrees Celcius
Answer:
a)F =1.8C +32
b) f(22) = 68 F
c) C = 5/9F -17 7/9
d) 28.3
slope= 5/9
B= -17 7/9
Step-by-step explanation:
x1 y1 x2 y2
0 32 100 212
(Y2-Y1) (212)-(32)= 180 ΔY 180
(X2-X1) (100)-(0)= 100 ΔX 100
slope= 1 4/5
B= 32
Y =1.8X +32
