Which number line represents all of the values of x for the equation x2 = 64?
Answers
x = + - 8
hope it helps
Answer:
We are asked to find all the values of x on the number line that satisfies the given quadratic equation:
[tex]x^2=64[/tex]
We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.
on taking the square root on both the side of the equation we obtain:
[tex]x=\pm 8[/tex]
Hence we get two points on the number line.
x=8 and x= -8.
These are the discrete values we did not get any interval of the solution.

Twenty-one out of 70 customers at the restaurant ordered dessert. What percentage of the customers did not order dessert?
Answers
To find your answer you must subtract first:
70 - 21 = 49
Now, how much percent is 49 of 70?
49/70 = 0.7000
0.7000 * 100 = 70.00%
49 is 70% of 70.
I really hope this helped you! :)
To check your answer: (70 × 70.00)/100 = 49
70 - 21 = 49
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
[tex] \frac{49}{70} [/tex] = [tex] \frac{x}{100} [/tex]
Cross multiply.
70x = 4,900
Now, all you would need to do is isolate the x. To do this, you would divide both sides by 70.
x = 70
x = 70%
So, 70% of the customers ordered dessert.

Number 18 pls help me
Answers
Following PEMDAS, we first focus on the parenthesis. So we simplify 9-3 to get 6
So we go from
18*4^2+(9-3)^2
to
18*4^2+6^2
The next step is applying exponents. In this case, squaring the terms, so we go from
18*4^2+6^2
to
18*16+36
Next is multiplying
18*16+36
turns into
288+36
Finally, add up 288 and 36 to get 288+36 = 324
That confirms that Lila is correct
----------------------
The error that Rob made is that he computed 18*4^2+9^2-3^2 but it is NOT correct. Saying (x-y)^2 = x^2-y^2 isn't a true equation for all x and y. Again you have to simplify what is in the parenthesis first, and then you can square it. Or you must use the FOIL rule to expand out (9-3)^2

Correct me if I'm wrong.
The equation that could be used to find the number of T-shirts sold is [tex]14t + 25(200-t) = 3515[/tex] and this can be determined by forming the linear equation.
Given :
A store sells T-shirts for $14 and sweatshirts for $25. The store sells 200 items and earns $3,515 in sales.The following steps can be used in order to determine the equation that could be used to find the number of T-shirts sold:
Step 1 - Let the total number of T-shirts be 't' and the total number of sweatshirts be 's'.
Step 2 - The linear equation that represents the total number of items is:
[tex]t + s = 200[/tex]
[tex]s = 200 - t[/tex] --- (1)
Step 3 - The linear equation that represents the total earning is:

An angle measures 102° less than the measure of a supplementary angle. what is the measure of each angle?
Answers
The measure of two angles are 141° and 39°.
What are supplementary angles?When the sum of two angles equals to 180°, then those angles are said to be supplements of each other and hence called supplementary angles.
Given that, An angle measures 102° less than the measure of a supplementary angle.
Let the angles be x and y, then according to question,
x+y = 180°
x-y = 102°
Solving the equation by elimination method, we get,
2x = 282°
x = 141°
Put x = 141°
141°-y = 141°
y = 39°
Hence, the asked angles are 141° and 39°

#SPJ2
To find the measures of the angles, set up an equation using the property that supplementary angles add to 180 degrees. Solving the equation yields one angle measuring 39 degrees and the supplementary angle measuring 141 degrees.
When dealing with angles and their measurements, it's important to remember fundamental properties, such as the fact that the sum of supplementary angles is 180 degrees. Given that an angle is 102° less than its supplementary angle, we can set up an equation to find the measure of each angle. Let's call the first angle x; therefore, the supplementary angle will be x + 102°.
Using the property that the sum of supplementary angles is 180°, we can write the equation:
x + (x + 102°) = 180°
2x + 102° = 180°
2x = 180° - 102°
2x = 78°
x = 39°
Thus, the measure of the first angle is 39° and that of the supplementary angle is 39° + 102° = 141°.
Sandy can jog 3 2/5 miles in 5/6 hour. Find her average speed in miles per hour.
Answers
(17/5 mi)/(5/6 hr) = 102/25 mi/hr
Answer:
[tex]4\frac{2}{25}[/tex] miles per hour
Step-by-step explanation:
Sandy can jog a distance [tex]3\frac{2}{5}[/tex] miles or [tex]\frac{17}{5}[/tex] in the duration = [tex]\frac{5}{6}[/tex] hours
Since speed = [tex]\frac{distance}{time}[/tex]
We plug in the values of distance and time in the formula of speed.
Speed = [tex]\frac{\frac{17}{5}}{\frac{5}{6}}[/tex]
= [tex]\frac{17}{5}[/tex] × [tex]\frac{6}{5}[/tex]
= [tex]\frac{102}{25}[/tex]
= [tex]4\frac{2}{25}[/tex] miles per hour
Her average speed is [tex]4\frac{2}{25}[/tex] miles per hour.

That is the answer because if you are x feet above sea level, to get back to sea level, which equals zero (0), you need to go down the same amount you went up (x), so you need to go down x feet (-x).
-3 times what equals 9
Answers
x = 9 / (-3)
x = -3 <== so -3 * -3 = 9
The value to fill in the blank is -3.
So, -3 x -3 = 9.
We have,
To solve the equation -3 x __ = 9, we need to find the value to fill in the blank that makes the equation true.
Let's denote the value we need to find as "x".
When we multiply -3 by "x", it means we are adding -3 to itself "x" times.
So, the equation becomes -3 times "x" equals 9:
-3x = 9.
To solve for "x", we can divide both sides of the equation by -3:
-3x / -3 = 9 / -3
This simplifies to:
x = -3
Therefore,
The value to fill in the blank is -3. So, -3 x -3 = 9.

A)It is impossible to construct a triangle with these angle measures.
B)There is one possible triangle with these angle measures.
c)There are many possible triangles with these angle measures.
D)There are many possible similar triangles with these angle measures.
Answers
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Measures of angles are as follows:
125°, 15°, 40°
As we know the sum of all angles in a triangle is supplementary i.e. 180°.
∠A+∠B+∠C=180°
125°+15°+40°=180°
Therefore, it is satisfying the angle sum property.
So, it can form a triangle.
Now, we will check for uniqueness.
As similar triangles need two angles to be equal by AA criteria , their sides can vary with two equal angles.
Hence, there is possibility to have many possible similar triangles with angle measures.
Therefore, Option 'D' is correct.
