Write each of
these ratios in
their simplest form.
A) 3:9 B) 12:36 C) 13:39 D) 71:213
E) 142:213 F)38:57 G) 33:44 H) 31:42

b) 1:3
c) 1:3
d) 1:3
e) 2:3
f) 2:3
g) 3:4
h) 31:42
Step-by-step explanation:
3:9=1:3
12:36=1:3
13:39=1:3
71:213=1:3
142:213=2:3
38:57=2:3

the simplest form of 31:42 is 31:42 because 31 is prime number so we can't divide it.
Marcus is building a fence around his rectangular backyard. The length of his backyard is
75
3/4
ft, and the width is
81
1/4
ft. If the fence is
3/4
finished, how much fencing is left to complete?
Answer:
4,923.75ft²
Step-by-step explanation:
The area of the backyard = Length * width \
Area of the backyard = 75 3/4 * 81 1/4
Area of the backyard = 303/4 * 325/4
Area of the backyard = 6,154.6875ft²
If 3/4 of the fence is finished, the area of the finished part is expressed as;
Finished part = 1/5 * 6,154.6875
Finished part = 1,230.9375ft²
Part left unfinished = 6,154.6875-1,230.9375
Part left unfinished = 4,923.75ft²
Answer:235.5
Step-by-step explanation:
75 3/4= 75.75 (L). 81 1/4= 81.25 (W)
Perimeter= 314 3/4 of 314 is 235.5

What is the constant for 5c2+7d
Answer:
2
Step-by-step explanation:
5 and 7 are the coefficients if you need them
Can someone help me with this please
Answer:
Step-by-step explanation:
4) the first thing to notice is that the sides a and c are the same.. that's what the small marks are telling you... that are the same length. and since they are.. this is an isosceles triangle and the two angle at the base .. along the b side will be the same.. so solving y is just the same as A or 52°
then to solve for x we also need to use that the triangle add up to 180° on those inside angles..
180= 52+52+14x+6
maybe you can solve it from here.. but i'll do it quickly
70 = 14x
5=x
5) the exterior angle at C is 146 the total angle is 180 so the angle inside the triangle is 180=146+x x= 34°
then use that the interior of the triangle add up to 180 again
180 = 34 + 5y+3 + 4y + 8
180 = 45 +9y
135 =9y
15 = y

Answer:
C. x > -7 and x <= 3
Step-by-step explanation:
-3 < x + 4 <= 7
Subtract 4 from the three expressions.
-7 < x <= 3
-7 < x means x > -7.
Then you have x <= 3.
Answer: C. x > -7 and x <= 3

evaluate the following surds √2+√5
Answer:
The answer of the addition is;
√2+√5
Step-by-step explanation:
Here, we want to evaluate the given sure
Basically, we want to add the two surds together
In the case of this question, since they have nothing in common, the addition of both will give the same results
Thus;
√2+√5 = √2+√5

which expression shows the correct way to expand (6x-6)^2?
Answer:
[tex](6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36[/tex]
Step-by-step explanation:
Even if I don't know the options I can give all the option that will be right for expending this. Just look at each step and see which one is one of the options.
[tex](6x -6)^{2} = (6x +6)(6x +6) = 36x^{2} -72x + 36[/tex]

what is the value of x? -6x=90
Please show you got the answer
Answer:
-15
Step-by-step explanation:
-6x = 90
x = 90 ÷ -6
x = -15
Answer:
X = -15
Step-by-step explanation:
90/-6 is equal to -15.
You divide the number from the side with the variable from the other side of the = sign.
A square of side 72 cm and a rectangle of length 90 cm have same perimeter. Find the difference in areas ?
A)216cm2
B)304cm2
C)324cm2
D)328cm2
Answer:
324 cm²
Step-by-step explanation:
→ Work out perimeter of square
72 + 72 + 72 + 72 = 288
→ Work out the width of the rectangle
288 - (90 × 2) = 108
108 ÷ 2 = 54
→ Work out area of square
72 × 72 = 5184 cm²
→ Work out area of rectangle
90 × 54 = 4860 cm²
→ Minus the areas from each other
5184 cm² - 4860 cm² = 324 cm²
Answer:
C) 324cm²
Step-by-step explanation:
1) they have the same perimeter so to find it you add all four sides of the square because they are all the same ( 72+72+72+72=288)
2) now you multiply 90 by 2 because the rectanglehas to sides of the same length(90×2=180) the answer you get you are going to subtract to 288 (288-180=108)
3) now divide 108 by 2 (108÷2= 54) the answer you get equals the width of the side of the rectangle
4) to get the area of the rectangle you multiply 54 with 90 (54×90=4,860) to get the area of the square you multiply 72 times 72 (72×72=5,184)
5) now you subtract 5,184 and 4,860 ( 5,184-4,860= 324cm²)

BUSINESS a printing press valued at $120,000depreciates 12% per year. What will be the approximate value for the printing press in 7 years?
A. $19,200 B. $265,282 C. $49,041 D. $55,728
Answer:
19200
brainliest if correct
Explanation
12% of 120,000 = 14400
14400x7 = 100800
120,000 - 100800 = 19200

Is this right, if not then what is the equivalent expression of it, please make the answer easy and simple
Answer:
[tex]\dfrac{6x+2}5}[/tex]
Step-by-step explanation:
The given expression is :
[tex]\dfrac{3x}{5}+\dfrac{2}{5}+\dfrac{3x}{5}[/tex]
We need to write the equivalent expression for the above expression.
Taking like terms together,
[tex]=(\dfrac{3x}{5}+\dfrac{3x}{5})+\dfrac{2}{5}\\\\=\dfrac{3x+3x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x}{5}+\dfrac{2}{5}\\\\=\dfrac{6x+2}5}[/tex]
So, the equivalent expression is [tex]\dfrac{6x+2}5}[/tex].
a motorboat moves across a lake at a constant speed. when it begins it from the shore. after 9 minitues it is 14 km from the shore. which function decribes the motorboat distance from the shore?
a. y= 4x + 50
b. y= -4x + 50
c. y= 9x + 50
d. y= -9x + 50
Answer:
Answer:
The function describes the motorboat's distance from the shore
Step-by-step explanation:
A motorboat moves across a lake as a constant speed. when it begins, it is 50 km from the shore
After 9 minutes, it is 14 km from the shore.
So, rate of change =
Negative sign shows that there is decrease in distance per minute
The rate of change of distance is 4 km / minutes
General equation : y = mx+c
Where m is the slope and c is the constant
Substitute the values in the equation :
y=-4x+50
Where y is the final distance and x is the minutes
So, Option C is true
Hence The function describes the motorboat's distance from the shore
