How many solutions does the equation
1-(6x - 4) = 3(1 – x) have?
Answer: one solution
this is all i know
Answer:
D
Step-by-step explanation:
Given
1 - [tex]\frac{1}{2}[/tex] (6x - 4) = 3(1 - x) ← distribute parenthesis on both sides
1 - 3x + 2 = 3 - 3x
3 - 3x = 3 - 3x
Since both sides of the equation are the same , then
This indicates the equation has infinitely many solutions.
pls help what is 66 2/3 % of 9/10 of $45.00
*pls include steps tysm
Answer:
$27.00
Step-by-step explanation:
We first have to start at the base value of $45.00, as without that, we have nothing to go off of. We can work right to left because we start at the rightmost point of the problem.
Therefore, we start with finding 9/10 of 45.00 . This is as simple as multiplying 9/10 with 45.00, resulting in 40.5
To figure out a percentage relative to real numbers, we first have to turn that percentage into a fraction or decimal. To turn it into a decimal, we simply divide by 100, and 66 2/3 divided by 100 is roughly 0.6666 , or 2/3 . Multiplying our result of 40.5 by this, we get $27.00 as our answer.

A grocery store sells a bag of 4 oranges for $2.84. If arianna spent &3.55 on oranges, how many did she buy?
Answer:
5 dollors i just tookthe test 4
Step-by-step explanation:
Arianna bought 0 bags of oranges. It's possible that she may have bought other items along with the oranges or there might be a pricing discrepancy.
To find out how many oranges Arianna bought, we can use the given price of a bag of 4 oranges and the total amount she spent on oranges.
Let's set up a proportion:
Price of a bag of 4 oranges = $2.84
Amount Arianna spent on oranges = $3.55
Let "x" be the number of bags of oranges Arianna bought.
Since each bag contains 4 oranges, the total number of oranges she bought is 4 times the number of bags (4x).
Now, we can set up the proportion:
(Price of a bag of 4 oranges) / (Amount spent on oranges) = (Number of bags bought) / 4x
$2.84 / $3.55 = 1 / 4x
To solve for "x," cross-multiply:
$2.84 * 4x = $3.55 * 1
11.36x = 3.55
Now, solve for "x":
x = 3.55 / 11.36
x ≈ 0.3125
Since we can't buy a fraction of a bag, we round the value of "x" to the nearest whole number:
x ≈ 0 (rounded to the nearest whole number)
So, Arianna bought 0 bags of oranges. It's possible that she may have bought other items along with the oranges or there might be a pricing discrepancy.

What is the nth term rule of 7,9,11,13,15
Answer:
[tex]a_{n}[/tex] = 2n + 5
Step-by-step explanation:
There is a common difference between consecutive terms, that is
9 - 7 = 11 - 9 = 13 - 11 = 15 - 13 = 2
This indicates the sequence is arithmetic with nth term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 7 and d = 2 , then
[tex]a_{n}[/tex] = 7 + 2(n - 1) = 7 + 2n - 2 = 2n + 5

help me find the size of the rhombus :)
Answer:
Step-by-step explanation:
The diagonals of a rhombus divides it into four congruent right triangles. Each triangle is a mirror image of the adjacent.
Therefore angle 2 is the alternate interior angle of 57°, and angle 3 is the mirror image, so also 57°.
Angles 1 is the complement of angle 3, and angle 4 is equal to the complement of angle 2 , so both equal 90-57 = 33°.
To summarize,
angle 1 = 33°
angle 2 = 57°
angle 3 = 57°
angle 4 = 33°

What is the relative frequency (to the nearest percent) of boys among those who cannot bike to school
Answer:
29%
Step-by-step explanation:
From the two way table given : the relative frequency of boys among those who cannot bike to school ;
Here, we are only concerned with thilose who cannot Bikento school and not all of the data :
The relative frequency of boys among those who cannot bike to school is :
Number of boys who can't bike to school / total number of people who can't bike to school
Number of boys who can't bike = 4
Total who cannot bike = 14
Hence, 4 /14 = 0.2857142
0.2857142 * 100% = 28.57% = 29% (nearest percent)
Complete the solution of the equation. Find the
value of y when x equals -8.
4x + 9y = -14
does anyone know what this is?
Answer:
Y is equal to 2
Step-by-step explanation:
X equals -8
So,
4(-8) + 9y = -14
-32 + 9y = -14
-32 + 32 + 9y = -14 + 32
9y = 18
1/9 × 9y = 18 × 1/9
y = 2

What is Geometric Transformation?Transformation of geometrical figures or points is the manipulation of a given figure to some other way.
Different types of transformations are Rotation, Reflection, Glide reflection, Translation and Dilation.
Dilation is a type of transformation where the figure is enlarged or made smaller such that it preserves the shape but not size.
In Reflection the figure is flipped. In other words, a figure when undergoes reflection becomes it's mirror image.
Dilation preserves the angle measures, so the triangles will be similar.
Reflection, on the other hand, will result in congruent triangles.
Student 1 said that Reflect △ABC across the y-axis and then dilate it by a scale factor of 1 with the center of dilation at the origin.
If the scale factor is 1, then the dilated image will be the same as the original image.
So the resulting triangle will be congruent to the original triangle.
In the case of what student 2 said, scale factor is 2. Triangle is enlarged.
So the resulting image will be similar to the original one.
Hence student 2 is correct.

Let Tn be the nth triangular number, Qn be the nth square number and
Pn be the nth pentagonal number.
(a) Show that 3Pn = T3n-1.
(b) Show that Pn - Qn = Tn-1 and hence that P3n - 3Pn = Q3n.
It has been shown that [tex]3P_{n} =T_{3n-1}[/tex], [tex]3P_{n} =T_{3n-1}[/tex] and hence [tex]3P_{n} =T_{3n-1}[/tex].
Given: [tex]T_{n}[/tex] is the nth triangular number. [tex]Q_{n}[/tex] is the nth square number. [tex]P_{n}[/tex] is the nth pentagonal number.
To show:
[tex]3P_{n} =T_{3n-1}[/tex] [tex]P_{n} -Q_{n} =T_{n-1}[/tex] and hence [tex]P_{3n} -3P_{n} =Q_{3n}[/tex]Triangular numbers are numbers formed by addition of consecutive natural numbers starting from 1. Square numbers are numbers formed by squaring natural numbers. Pentagonal numbers are numbers formed by distinct dots in a pattern of dots consisting of the outlines of regular pentagons with sides up to n dots, when the pentagons are overlaid so that they share one vertex.
The formula for each of them is given by:
[tex]T_{n}=\frac{n(n+1)}{2}[/tex]
[tex]Q_{n}=n^{2}[/tex]
[tex]P_{n}=\frac{3n^{2}-n}{2}[/tex]
(a).
Now, put [tex]n=3n-1[/tex] in [tex]T_{n}=\frac{n(n+1)}{2}[/tex] to get,
[tex]T_{3n-1}=\frac{(3n-1)(3n)}{2}[/tex]
[tex]T_{3n-1}=3\frac{n(3n-1)}{2}[/tex]
[tex]T_{3n-1}=3\frac{3n^{2}-n}{2}[/tex]
Put [tex]P_{n}=\frac{3n^{2}-n}{2}[/tex] in [tex]T_{3n-1}=3\frac{3n^{2}-n}{2}[/tex] to get,
[tex]T_{3n-1}=3P_{n}[/tex]
So, [tex]3P_{n}=T_{3n-1}[/tex]
(b).
Now,
[tex]P_{n}-Q_{n}=\frac{3n^{2}-n}{2}-n^{2}[/tex]
[tex]P_{n}-Q_{n}=\frac{3n^{2}-n-2n^{2}}{2}[/tex]
[tex]P_{n}-Q_{n}=\frac{n^{2}-n}{2}[/tex]
Put [tex]n=n-1[/tex] in [tex]T_{n}=\frac{n(n+1)}{2}[/tex] to get,
[tex]T_{n-1}=\frac{(n-1)(n-1+1)}{2}[/tex]
[tex]T_{n-1}=\frac{(n-1)n}{2}[/tex]
[tex]T_{n-1}=\frac{n^{2}-n}{2}[/tex]
Comparing [tex]P_{n}-Q_{n}=\frac{n^{2}-n}{2}[/tex] and [tex]T_{n-1}=\frac{n^{2}-n}{2}[/tex], we get,
[tex]P_{n}-Q_{n}=T_{n-1}[/tex]
Now, put [tex]n=3n[/tex] in [tex]P_{n}-Q_{n}=T_{n-1}[/tex] to get,
[tex]P_{3n}-Q_{3n}=T_{3n-1}[/tex]
As shown in part (a), [tex]T_{3n-1}=3P_{n}[/tex]
Put [tex]T_{3n-1}=3P_{n}[/tex] in [tex]P_{3n}-Q_{3n}=T_{3n-1}[/tex] to get,
[tex]P_{3n}-Q_{3n}=3P_{n}[/tex]
[tex]P_{3n}-3P_{n}=Q_{3n}[/tex]
So, [tex]P_{n}-Q_{n}=T_{n-1}[/tex] and hence [tex]P_{3n}-3P_{n}=Q_{3n}[/tex]

A petrol can is a rectangular prism with base measurements 15 cm by 30 cm. If the can has capacity 18 liters, find its height.
Answer:
40
Step-by-step explanation:
The first step is to calculate the base area of the prism
= 15×30
= 450
The volume is then calculated as follows
= 450×h
= 450h
The capacity is 18 liters
= 18×1000
= 18,000
Therefore the height of the rectangular prism can be calculated as follows
450h= 18,000
h= 18,000/450
= 40
Hence the height is 40 cm
