Answer:
FALSE
Step-by-step explanation:
if you didnt know those little bars mean absolute value and the absolute value of a negative number is the same number but while positive if that makes sense so the equation is pretty much saying 2≥3 which is not true

2 power x+1 minus 2power X-2
how do you know when the solution of equations is a precise answer and when it is an approximate answer?
Answer:
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11
A basketball player attempted 24 shots and made 13

Find the value of x that makes m||n. (7x - 23) (11x + 23)
(7x - 23)° + (11x + 23)° = 180°
7x - 23° + 11x + 23° = 180°
18x = 180° / : 18
x = 10°
help me please this will help my grade !
Answer:
the answers B and D are correct
Answer:
B & D
Step-by-step explanation:
It can-t be A, because that would mean 20², which equals 400, would equal 20.
B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.
C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.
D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.
E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong
Hope this helps :)
Eight more than seven times a number is -20
Answer: The number is 0
Step-by-step explanation:
8 = 7x + 8
Then we solve it:
8 = 7x + 8
8 - 8 = 7x
0 = 7x
0 ÷ 7 = x
x = 0
hope this helps have a nice day

Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

A certain drug is made from only two ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1012 milliliters of the drug, how many milliliters of compound A are needed?
These are proportions.
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)

What is equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign. In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.
here, we have,
Given the equation y=-2x+1
and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect.
Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel.
To have this result, we must have that they have the same slope but different y intercept.
That is take m = -2 and b any value different to +1. For example, the b = 6.
So, y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.

John is in charge of making a banner for the basketball game this Saturday. He measures how long the banner is before painting it. He finds it measures 10 meters?
Complete question :
Jane is in charge of making a banner for the basketball game this Saturday. She measures how long the banner is before painting it. She finds it measures 10 meters.
Which measurement did Jane find?
Answer:
Length
Step-by-step explanation:
The length of measured object gives how long the object or material is. And it is usually measure in meters, feets, inches, centimeters and so on. In the scenario above, the measurement is given in meter unit. This means that, the length of the banner measured by Jane is 10 meters long.
A banner may be squared or rectangular in shape. Which ever shape it takes, the other dimension of the banner would be its wideness which is given by the measured width or breadth of the banner.
4. A rectangular field has a length of 115 yards and a diagonal length of 135 yards. Which
measurement is closest to the width of the field in yards?
F 20 yd
G 71 yd
H 177 yd
J 250 yd
Answer:
h

Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.
Find the measures of the numbered angles in the kite.
Answer:
m1=m2 = 111 degrees
Step-by-step explanation:
1. construct a line between angles 1 and 2
//now we have 2 triangles. They are both isoscles triangles.
3. m(base angles in 90 triangle) = (180-90)/2 = 45 degrees. (base angle th.)
4. m(base angles in 48 triangle) = (180-48)/2 = 66degrees. (base angle th.)
5. m1 = 66+ 45 = 111 degrees. (algebra)
6. m2=m1 = 66+45 =111 degrees (algebra)
check:
sum of all angles has to add up to 360 degrees.
48 + 90+ 111+111=360
360=360

3.A cuboid has a volume of 384 cm. If the base and height are both 8cm, what is the length of
the cuboid?
Answer:
l = 6 cm
Step-by-step explanation:
Given that,
The volume of a cuboid, V = 384 cm³
The base and height are 8 cm
We need to find the length of the cuboid. The formula for the volume of a cylinder is given by :
[tex]V=l\times b\times h\\\\l=\dfrac{V}{bh}\\\\l=\dfrac{384}{8\times 8}\\\\l=6\ cm[/tex]
So, the length of the cuboid is 6 cm.
2x+3y=15
x+y=6
wats the value of x and y?
Answer:
2x + 3y = 15
x + y = 6 --> 2x + 2y = 12
By elimination method
2x + 3y = 15
-2 - 2y= -12
y = 3
x + y = 6
--> x = 3

1) What is the surface area?
1 ft
8 ft
4 ft
Answer:
88 ft^2
Step-by-step explanation:
For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions
1 ft by 8 ft,
two opposite faces with dimensions
1 ft by 4 ft,
and two opposite faces with dimensions
4 ft by 8 ft.
We find their area and add them.
SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft
SA = 16 ft^2 + 8 ft^2 + 64 ft^2
SA = 88 ft^2
