twice a number when described by 7 gives 45 . find the number. and also who wants to talk im bored
Answer:
Answer
Let the number be x.
twice =2x
When it is decreased by 7 we get the following equation:
2x−7=45
⇒2x=45+7
⇒2x=52
⇒x=252
∴x=26
The number is 26.

The bill is $62.78 the tax on the bill is 8% how much tax is owed
Answer:
$5.0224
Step-by-step explanation:
8%=0.08
0.08*62.78=5.0224
Answer:
$5.0224
if they want you to round its - $5.02
Step-by-step explanation:
8% of 62.78 = 8% x 62.78
8/100 x 62.78 === 502.24 /100
502.24 / 100 = $5.0224

Someone already answered b, c, and 2 so here's the third answer :)
10:50 is a ratio, which can be rewritten as [tex]\frac{10}{50}[/tex]
To write an equivalent fraction, we can either multiply or divide.
Multiplying both the numerator and denominator by 2 gets us [tex]\frac{20}{100}[/tex].
Dividing both the numerator and denominator by 10 gets us [tex]\frac{1}{5}[/tex].

Given two concentric circles (circles that have the same center point), with the inner circle having a radius of 1 r and the outer one having a radius of 2 r as shown, give a dilation that would map the inner circle onto the outer circle.
Answer:
(x, y) ⇒ (2x, 2y)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, translation, rotation and dilation.
Dilation is the increase or decrease in size of a figure. If a figure with point A(x, y) is dilated by a scale factor of k, the new location is at A'(kx, ky). If k > 1, it is an enlargement and if k < 1, it is a reduction.
Given that the inner circle has a radius of 1 r and the outer one has a radius of 2 r. To map the inner circle onto the outer circle, the inner circle would need to be enlarged. The scale factor is:
k = outer circle radius / inner circle radius = 2r / 1r = 2
A dilation with a scale factor of 2 would be needed to map the inner circle onto the outer circle.
That is:
(x, y) ⇒ (kx, ky)
The dilation should be (x, y) ⇒ (2x, 2y)
What is transformation and dilation:Transformation refers to the point movement that starts from beginning location to the new location. The dilation refers to the increment or decrement of the figure size.
Here,
The scale factor should be calculated by dividing the outer circle radius from the inner circle radius
[tex]= 2r\div 1r[/tex]
= 2
Therefore, The dilation should be (x, y) ⇒ (2x, 2y)

Two supplementary angles that are 4x and 5x what is the value of x
Answer:
x = 20
Step-by-step explanation:
4x + 5x = 9x
9x = 180 (supplementary angles add up to 180 degrees)
Divide 180/9 = 20
Answer:
x = 20.
Step-by-step explanation:
Supplementary angles sum to 180, so:
4x + 5x = 180
9x = 180
x = 20.
Simplify completely. Leave your answer in exponential form:
Answer:
[tex] {2}^{3} \times {4}^{3} \times 9[/tex]
Step-by-step explanation:
Using the division rule when dealing with exponents
[tex] \frac{b {}^{h} }{b {}^{j} } = b {}^{h - j} [/tex]
meaning that when we divide exponents that have the same base but different powers we can subtract the power of the bottom exponent from the top exponet.
so using that we are going to do 2, 4 and 9
[tex] \frac{2 {}^{8} }{ {2}^{5} } = {2}^{8 - 5 = 3 \: \: \: \: \: 2 {}^{3} } [/tex]
[tex] \frac{ {4}^{4} }{ {4}^{1} } = {4}^{4 - 1} \: \: \: {4}^{3} [/tex]
[tex] \frac{9 {}^{9} }{ {9}^{8} } = {9}^{9 - 8} = 9 {}^{1} [/tex]
Combine all the terms and we get
[tex] {2}^{3} \times 4 {}^{3} \times {9}[/tex]

four numbers, O through 9. How many possible combinations
exist for his locker?
Answer: 0-999
Step-by-step explanation: So we know that there is 10 numbers, and we know that we can do the same number more than once, so
10 to the fourth power equals 10,000
So the digits could be up to 0000 to 9999

Someone help me (10 points each person)
Answer:
x=56
Step-by-step explanation:
Alternate exterior angles are congruent if the lines crossed by the transversal are parallel (which they are).
Answer:
56
Step-by-step explanation:
It would also be 56 degrees because if both 360 degree angles are parallel to each other and if each of the 360 degree angles had two top and bottom 180 degree angles and if 56 was subtracted to 180 you would get 124 and when you plus that with 56, you get 180 so if that is true for all 4 180 degree angles in this problem, then X would equal 56 no doubt.

A circle has equation
x2 + y2 = 8
Find the area of the circle.
Answer:
x=4 y=0 or x=2 y=2 or x=0 y=4
Step-by-step explanation:
Answer:
because the circle has equation: x² + y² = 8
=> the circle has the centre I(0;0)
the radius R = 2sqrt(2)
=> the area of the circle =
[tex](2 \sqrt{2})^{2} \times \pi = 8\pi =23.13 [/tex]

What is the solution set of 4x = y and [tex]2x^{2} -y=0[/tex]
A.
{(0.5, -0.5), (2, -8)}
B.
{(0, 0), (2, 8)}
C.
{(1.5, 2), (8, 2)}
D.
{(-1.5, -2), (2, 8)}
Answer:
B.
{(0, 0), (2, 8)}
Step-by-step explanation:
Substitute 4x in for y in the second equation.
[tex]2x^{2} - 4x = 0\\[/tex]
2x(x - 2) = 0
x = 0 or x - 2 = 0
x = 2
Substitute x = 0 and x = 2 in the first equation to get the corresponding values for y
4(0) = y and 4(2) = y
y = 0 or y = 8
So, B is the correct answer
