Estimate the quotient of 41 ÷ 7.94.
4
5
6
7
Answers
Answer:
5
Step-by-step explanation:
Since 7 into 42 is six we know the answer can't be 7 because it's too high. We can also rule out 6 because 6 times 7.94 is more than 41. The first answer choice is wrong because if you take away the .94, 7 times 4 is 28 which is pretty far from 41. If you multiply 5 and 7, it comes out to 35. That's significantly closer than four.

the convex polygon below has 7 sides. find the value of x
Answers
Hence its sum of interior angles is given by the formula , (number of sides-2)x180°
=> (7-2) x 180°
=> 5 x 180°
=> 900°
The sum of all angles must be equal to 900°
The given six angles are :
139°,126°,106°,129°,141°,112° , x°
=> 139+126+106+129+141+112+x = 900°
=> 753 + x = 900
=> x = 900-753
=> x = 147°
Hence 147° is the required answer.
Answer:
x = 147
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 7 , then
sum = 180° × 5 = 900°
sum the interior angles and equate to 900
x + 141 + 112 + 129 + 106 + 139 + 126 = 900
x + 753 = 900 ( subtract 753 from both sides )
x = 147

If AC is congruent to BD and EC is congruent to ED, prove that AE is congruent to BE
Answers
AE and BE are congruent lines or we can say lines with same length.
What are congruent lines?
Congruent line segments are geometrical figures in one dimension with identical dimensions. In terms of congruent lines, the word "congruent" refers to the equality of the two line segments. When two lines are the same length, they are said to be congruent.
As given in the question,
AC = BD, and
EC = ED
We can see in the figure that:
AC - EC = AE ___(1)
BD - ED = BE ___(2)
Substituting the value of AC and EC in equation (1):
AE = BD - ED ___(3)
From equations (2) and (3), we can conclude that,
AE = BC
Therefore, AE and BE are congruent lines.

10. What is m/ABD in the figure shown?
Answers
The measure of m∠ABD in the figure shown is 19°.
Given:
∠BCD = 71°
In the figure, ΔABC is an isosceles triangle where AB = BC.
According to the Isosceles Triangle Theorem, an isosceles triangle has equal angles on either side of its equal sides.
So, ∠BAD = ∠BCD = 71°
The sum of angles in a triangle sums to 180°.
∠ABC + ∠BAD + ∠BCD = 180°
∠ABC + 71° + 71° = 180°
∠ABC + 142° = 180°
∠ABC = 180° - 142° = 38°
DB is the angle bisector of ∠ABC.
Now, ∠ABD = ∠CBD = 38°/2 = 19°
The measure of ∠ABD is 19°.

At the beginning of the year, Josue had $70 in savings and saved an additional $9
each week thereafter. Arianna started the year with $30 and saved $19 every week.
Let J represent the amount of money Josue has saved t weeks after the beginning of
the year and let A represent the amount of money Arianna has saved t weeks after
the beginning of the year. Write an equation for each situation, in terms of t, and
determine the interval of time when Josue has more in savings than Arianna.
Answers
There will be no interval of time when Josue has more in savings than Arianna, they have same savings is after 4 weeks
How to calculate the above question?Step one:
For Josue
initial savings balance= $70
weekly savings = $9
Let J represent amount of money Josue has saved and t the number of weeks after the beginning of the year
The total amount in the savings after t weeks is
J=9t+70-------1
For Arianna
initial savings balance= $30
weekly savings = $19
Let A represent the amount of money Arianna has saved and t the number of weeks after the beginning of the year
The total amount in the savings after t weeks is
J=19t+30---------2
Step two
equation 1 and 2 to find t
9t+70=19t+30
9t-19t=30-70
-10t=-40
divide both sides by 10
t=4
t=4 weeks
so after 4 weeks Josue and Arianna will have the same amount of money
For Josue t=4
J=9(4)+70-------1
J=36+70
J=$106
For Arianna t=4
A=19(4)+30---------2
A=76+30
A=$106
The two equations above shows that after 5 weeks their savings will be $106.

A)9(√3 −1)
B) 2√3
c) ³(√3-1)
D) 9-√3
Answers
Answer:
A
Step-by-step explanation:
using the sine ratio and the exact values
sin30° = [tex]\frac{1}{2}[/tex] and sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]
calculate the height of the wall below x , call it h
the hypotenuse is the length of the ladder
using the sine ratio in the lower right triangle.
sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{h}{18}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )
2h = 18 ( divide both sides by 2 )
h = 9
lower part of the wall is 9 meters
using the sine ratio in the right triangle on the right
sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{9+x}{18}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
2(9 + x) = 18[tex]\sqrt{3}[/tex] ( divide both sides by 2 )
9 + x = 9[tex]\sqrt{3}[/tex] ( subtract 9 from both sides )
x = 9[tex]\sqrt{3}[/tex] - 9 = 9([tex]\sqrt{3}[/tex] - 1)
Answer:
[tex]\textsf{A)} \quad x=9(\sqrt{3}-1)[/tex]
Step-by-step explanation:
Interior angles of a triangle sum to 180°. Therefore, if the ladder makes an angle of 30° with the ground, the angle it makes with the wall is 60°.
Therefore, the two triangles are congruent as their corresponding angles are the same and the length of their longest side (hypotenuse) is the same.
30-60-90 Triangle Theorem
A 30-60-90 triangle is a special right triangle where the measures of its angles are in the ratio 1 : 2 : 3 and the measure of its sides are in the ratio 1 : √3 : 2.
The formula for the sides is b : b√3 : 2b where:
b = the side opposite the 30° angle (shortest leg).b√3 = the side opposite the 60° angle.2b = the side opposite the right angle (hypotenuse).Therefore, as the length of the hypotenuse is 18:
[tex]\implies 2b=18[/tex]
[tex]\implies b=9[/tex]
[tex]\implies b\sqrt{3}=9\sqrt{3}[/tex]
To find x, subtract the length of the shortest leg of the right triangle from the length of the other leg of the right triangle:
[tex]\implies x=9\sqrt{3}-9[/tex]
[tex]\implies x=9(\sqrt{3}-1)[/tex]

By using the properties of the 30-60-90 right triangles, the lengths of the long leg and the hypotenuse are √3 · L and 2 · L, respectively.
What are the lengths of the hypotenuse and the long leg of the 30-60-90 right triangle?
Right triangles are triangles where one of its internal angles is a right angle, that is, has a measure of 90°. 30-60-90 triangles are right triangles whose internal angles have measures of 30°, 60° and 90°, respectively.
This kind of right triangles have the following features:
The long leg is adjacent to the least angle of the triangle, that is, the angle whose measure is 30°.The short leg is opposite to the least angle of the triangle, that is, the angle whose measure is 30°.The length of the long leg is √3 times the length of the short leg.The length of the hypotenuse is 2 times the length of the short leg.If we know that the short leg has a length of L, then the lengths of the long leg and the hypotenuse are √3 · L and 2 · L, respectively.

If test results over a long period of time show that of the values are over pounds and are under pounds, what are the mean and the standard deviation for the population of products produced with this process?.
Answers
Standard deviation of population mean is 0.33.
Why is there a standard deviation?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.it is shown that 5% values are over 2.1 pounds and 5% are under 1.9 pounds
so stastically that means
P( X > 2.1, μ; σ) = 0.05 and P( X 1.9; μ; σ) = 0.05
where μ is mean of the sample and σis the standard deviation of the sample.
so mean can be calculated easily μ = (2.1 + 1.9)/2 = 2.0
and as we can interpret P(1.9 <x < 2.1; 2.0; σ) = 0.90 by normal distribution the Z value for 90% confidence interval is 1.65
so σ = (2.1 -2) /1.65 = 0.06
standard deviation of the sample mean= 0.06
and by that standard deviation of population mean = 0.06 * (30) 0.5 = 0.33

The pole is cut into rods each of length 5.8 cm, correct to the nearest millimetre.
Calculate the largest number of rods that the pole can be cut into.
Answers
The largest number of rods that the pole can be cut into is 86.
Given:
Length of Metal Pole = 500 cm
The pole is cut into rods.
Length of each rod = 5.8 cm
To determine the number of rods we can divide the total length of the pole by the length of each rod.
Number of rods that the pole can be cut into = (Length of Metal Pole) ÷ (Length of each rod )
⇒ Number of rods = 500 ÷ 5.8 = 86.2 ≈ 86
Therefore, the largest number of rods that the pole can be cut into is 86.
