What Two pairs of fractions are shown. Which symbol correctly compares 2/3 2/4 each pair of fractions?
Answer:
Greater than symbol.
2/3 > 2/4
Step-by-step explanation:
We have two fractions, 2/3 and 2/4
We then go back to the inequality part of mathematics where we have symbols such as greater than (>), less than (<), and equal to (=).
Of the three inequality symbols, we look and pick at the one that represents best, the fractions we were given.
2/3 and 2/4
With 2/3 being greater than 2/4.
2/3 = 0.67
2/4 = 0.50
Succinctly, 2/3 > 2/4.

Answer:
4. AC = 36
5. m<UTW = 42
Step-by-step explanation:
4.
AB = BC
-x + 25 = 3(2x - 8)
-x + 25 = 6x - 24
-7x = -49
x = 7
AC = 2(-x + 25) = 2(-7 + 25) = 2(18) = 36
AC = 36
5.
2x + 3 = 5x - 24
-3x = -27
x = 9
m<UTW = 2m<UTV = 2(2x + 3) = 2[2(9) + 3] = 2(21) = 42
m<UTW = 42
A bird sitting at the top of a tree looks down at an angle of 500 , at an earthworm on the ground. If the earthworm is 7m away from the base of the tree, determine the height of the tree to 1 decimal place.

Step-by-step explanation:
Given
The angle of declination is [tex]50^{\circ}[/tex]
Earthworm is [tex]7\ m[/tex] away from the base of the tree
Suppose h is the height of the tree
from the figure, we can write

Answer:
3. - 8n² -8n + 3
Step-by-step explanation:
(4n^4 - 8n +4) - (8n² + 4n^4 +1)
Firstly, open the brackets.
= 4n^4 - 8n +4 - 8n² - 4n^4 - 1
Now, group like terms.
= 4n^4 - 4n^4 - 8n² -8n - 1 + 4
4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4
= - 8n² -8n - 1 + 4
= - 8n² -8n + 3
in a class, the ratio of boys to girls is 8 to 5. if there are 75 girls in the class, how many boys are there in the class? process pls
Answer:
120
Step-by-step explanation:
boys : girls
8 : 5
x : 75
to find x, take 75 and divide it by 5:
75 ÷ 5 = 15
(you do this to determine how you can go from 5 to 75)
take the qoutient and multiply it by 8:
15 × 8 = 180
Find
(1) The total surface area of a closed cylindrical petrol storage tank whose diameter
4.2 m. and height 4.5 m.
(i) How much steel sheet was actually used, if 1/12
of the steel was wasted in making
of the tank. (anewer quickly and steps in order )
Answer:
The amount of steel used = 94.38 [tex]m^{2}[/tex]
Step-by-step explanation:
Height of the tank = 4.5 m.
Diameter of the tank = 4.2 m.
But,
radius = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{4.2}{2}[/tex]
radius = 2.1 m
Total surface area of a cylinder = 2[tex]\pi[/tex]rh + 2[tex]\pi[/tex][tex]r^{2}[/tex]
= 2[tex]\pi[/tex]r(r + h)
= 2 x [tex]\frac{22}{7}[/tex] x 2.1 (2.1 + 4.5)
= 44 x 0.3 (6.6)
= 87.12
Total surface area of a cylinder = 87.12 [tex]m^{2}[/tex]
Since [tex]\frac{1}{12}[/tex] of the steel was wasted, then;
[tex]\frac{1}{12}[/tex] x 87.12 = 7.26 [tex]m^{2}[/tex]
Actual area of steel sheet used = 87.12 + 7.26
= 94.38 [tex]m^{2}[/tex]
Thus, 94.38 [tex]m^{2}[/tex] of steel was used in making the tank.
Joshua's goal is to sell more than 20 items at a farmers' market. So far, he has sold 6 items. Each customer buys 2 items. Let c represent the number of additional customers Joshua must have to meet his goal.
Drag and drop the answer into the box to correctly complete the statement:
Joshua needs to have more than ___ additional customers to meet his goal
additional customers to meet his goal.
A. 3
B. 7
C. 8
D. 14
Answer:
20-6= 14
14 divided by 2 equals 7
he needs 7 more customers
Step-by-step explanation:
have a wonderful day! brainliest?
Answer:
B. (7)
Step-by-step explanation:
First, we figure out how many more items Joshua needs to sell so we do 20 - 6.
20 - 6 = 14.
Next, we do 14 / 2 because each customer buys 2 items.
14 / 2 = 7
Therefore, Joshua must have 7 additional customers to reach his goal.

The values of w is inversely proportional to m .If w=8 then m=25; what is m when w=20? Show me the steps please
Answer:
m = 10
Step-by-step explanation:
The values of w is inversely proportional to m
Mathematically:
w ∝ 1/m
w = k × 1/m
w = k/m
Where k is the Constant of Proportionality
Step 1
Solve for k
If w=8 then m=25
w = k/m
8 = k/25
Cross Multiply
k = 25 × 8
k = 200
Step 2
what is m when w=20? Show me the steps please
We solve for m
w = k/m
k = 200
20 = 200/m
Cross Multiply
20m = 200
m = 200/20
m = 10

Look at the picture. Are the triangles similar? If so, choose the answer that explains why.
Answer:
yes. by AAA, i think she mistyped an A not sure
Step-by-step explanation:
The remaining angle of the bigger triangle = 180 - 84.6 - 30.4 = 65 (angle sum of triangle)
The three angles are the same for both triangles
The triangles are similar to each other because the angle-angle theorem is satisfied.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangles are given.
Let the third angle of the triangle be x. Then we have
84.6° + 30.4° + x = 180
x = 65°
Then the triangles are similar to each other because the angle-angle theorem is satisfied.
Thus, the correct option is C.

Answer:
Step-by-step explanation:
so first what you want to do is split the shape in to
Draw a line down where the 2 is.
you should have a rectangle and a triangle
then you find the area of the rectangle
Rectangle:
5 x 2 = 10m^2
After than you try to find the triangles area
the bottom of the triangle is 9m but since to split it in 2 you will now have 7m
multiple 5 times 7 and you will receive 35 then you divide that by 2 and you will have 17.5m^2
Add your two areas together and you will get 27.5m^2
Use substitution to find the solutions to the systems.

Step-by-step explanation:
Xby the power of 5 times y to the power of 6 over 2 by the power of -2 times xby the power of 0times x by the power of 9
Answer:
We have the sentence:
"X by the power of 5 times y to the power of 6 over 2 by the power of -2 times x by the power of 0times x by the power of 9"
Let's break it into parts.
"X by the power of 5 times y to the power of 6..."
This can be written as:
x^5*y^6
"... 2 by the power of -2 times x by the power of 0times x by the power of 9"
This can be written as:
2^(-2)*x^(0)*x^(9)
And we have the quotient between the first thing and the second thing, then the equation is:
[tex]\frac{x^5*y^6}{2^{-2}*x^0*x^9}[/tex]
And any number by the power of 0 is equal to 1, then:
x^0 = 1, then we can rewrite the equation as:
[tex]\frac{x^5*y^6}{2^{-2}*x^9}[/tex]
We can keep simplifying this.
We know that:
a^(-n) = (1/a)^(n)
Then:
2^(-2) = (1/2)^2 = 1/4
Then we get:
[tex]\frac{x^5*y^6}{2^{-2}*x^9} = \frac{x^5*y^6}{x^9}*4[/tex]
And we also know that:
a^n/a^m = a^(n - m)
Then:
[tex]\frac{x^5*y^6}{x^9}*4 = 4*y^6*\frac{x^5}{x^9} = 4*y^6*x^{5 - 9} = 4*y^6*x^{-4} = \frac{4*y^6}{x^4}[/tex]
And we can't simplify this anymore.
