Answer:
X = -3333/100000
Step-by-step explanation:
Given that a rational number is such that when you multiply it by 5/2 and add 2/3 to the product you get 7/12, to determine what is the number the following calculation must be performed:
X x 5/2 + 2/3 = 7/12
2.5X + 0.666 = 0.583333
2.5X = 0.58333 - 0.6666
X = -0.08333 / 2.5
X = -0.033333
X = -3333/100000.

A company uses paper cups shaped like cones for its water cooler. Each cup has a height of 9cm, and the base has a radius of 4cm. How much water is needed to fill 150 cups? Use 3.14 for π, and do not round your answer.
Answer:
22608cm³
Step-by-step explanation:
Step 1
We find how many liters of water can be contained in 1 cup. We do this by finding the volume of the cup.
Cup is shaped as a cone
The volume of a cone = πr²h/3
Where
r = radius = 4cm
h = height = 9cm
π = 3.14
Hence,
Volume of the cone (cup) =
3.14 × 4² × 9/3
= 150.72 cm³
Step 1
How much water is needed to fill 150 cups?
1 cup = 150.72 cm³ of water
150 cups = x
Cross Multiply
x = 150 × 150.72 cm³
x = 22608 cm³ of water
Therefore, 22608cm³ of water is needed to fill 150 cups
heres my question : An altitude is drawn from the vertex of an isosceles triangle, forming a right angle and two congruent triangles. As a result, the altitude cuts the base into two equal segments. The length of the altitude is 36 inches, and the length of the base is 12 inches. Find the triangle’s perimeter. Round to the nearest tenth of an inch. Im pretty sure that were using the paythagerum therum.

What is the value of x? what is the measure of
Answer:
x = 21, ∠ ABE = 55°
Step-by-step explanation:
∠ ABD is right and
∠ ABE + ∠ DBE = ∠ ABD , that is
3x - 8 + x + 14 = 90
4x + 6 = 90 ( subtract 6 from both sides )
4x = 84 ( divide both sides by 4 )
x = 21
Then
∠ ABE = 3x - 8 = 3(21) - 8 = 63 - 8 = 55°
What is the new ratio?
6:12= 20: ?
Answer:
6:12 = 20:40
Step-by-step explanation:
[tex]\frac{6}{12} =\frac{20}{y}[/tex]
6:12 = 20:y
Cross multiply.
6 × y = 12 × 20
6y = 240
6y ÷ 6 = 240 ÷ 6
y = 40

3. A math teacher asked 60 randomly
selected seventh-grade students
whether they are left-handed or
right-handed. The table below
shows the results of this survey.
Left- or Right-Handed?
Hand Frequency
Left
18
Right
42
A school has a total of 280 seventh-
grade students. Based on the results
shown in the table above, how many
of those seventh-grade students
would you expect to be left-handed?
A 60
B 72
C 84
D 120
Answer:
c. 84 if wrong its 72 because im not sure if its esimated but if not its right.
Step-by-step explanation:
42x4.5=189
18x4.5=81
=270
84 of those seventh-grade students would you expect to be left-handed.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, have,
from 60 students ,
left handed = 18
now, from 280 students,
left handed = 280/60*18
=84
hence, 84 of those seventh-grade students would you expect to be left-handed.

The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6
inches
What is the approximate length of the cylinder's radius
Answer:
yo i do primavara to imma do 3.9
Step-by-step explanation:
oh and also if your grades are bad just do to the dashboard page and highlight you grade percentedge and click inspect if you know and if you see you number pecent on the inspect and right click and click edit as htl and change it to any percent you want then just click out of the inspec option and you will have A S AND B S
The approximate length of the cylinder's radius will be 3.3 inches. Then the correct option is A.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The longest straw that can fit inside a 5-inch cylindrical cup, if the straw is placed at an angle in the cup, is 6 inches.
Then the approximate length of the cylinder's radius will be given by the Pythagoras theorem.
Let x be the length of the radius. Then we have
x² = 6² - 5²
x² = 36 - 25
x² = 11
x = √11
x = 3.316
x ≅ 3.3

What is the value/expression for the side length highlighted in green.
Answer:
15
Step-by-step explanation:
The parallel lines divide the transversals proportionally.
The green length = 24 - c , then
[tex]\frac{24-c}{20}[/tex] = [tex]\frac{c}{12}[/tex] ( cross- multiply )
12(24 - c) = 20c ← distribute left side
288 - 12c = 20c ( add 12c to both sides )
288 = 32c ( divide both sides by 32 )
9 = c
Then
green length = 24 - 9 = 15

What is the length of the base of a triangle with a height of 7 and and area of 7?
Answer:
base = 2
Step-by-step explanation:
area = 1/2 base * height
7 = 1/2b * 7
7 = 7b/2
cross multiply
14 = 7b
divide both sides by 7
b = 2
Answer:
2
Step-by-step explanation:
So the formula for area of a right triangle is A=B*L*1/2
Variables to remember:
H=height
B=base
A=area
We know that 7=7*B* 1/2. Since they say area is 7, height is 7.
So, we know that L has to equal 1 to make 7*B=7
However, we must remember that this is *1/2. So to make area=7, we must get 14. To get 14, we must have 7*2*1/2, which would equal 14*1/2, equaling 7.
So the answer for B is:
2

Answer:
120cm2
Step-by-step explanation:
6 x 8 = 48cm2
8 x 9 = 72cm2
48 + 72 = 120cm2
Answer:
120 m^2
Step-by-step explanation:
The box on the left is 6m x 8m, thus the area would be 48 m^2.
The box on the right is 9m x 8m, thus the area would be 72 m^2.
Adding both areas would give you the total area of 120 m^2.
