Answer:
1.6
Step-by-step explanation:
Step one:
given data
x1=10
y1=16
x2=30
y2=48
Required
The slope of the given points
Step two:
The expression for the slope is
S= change in y/change in x
S= y2-y1/x2-x1
S= 48-16/30-10
S=32/20
S=1.6
Hence the slope is 1.6
1/15 + 1/5= 2/3 or 9/10

Show that b^2 is greater than equal to or less than ac, according as a, b, c are in A.P., G.P.
Or HP
arithmetic mean is 25 and geometric mean is 20.
Answer/Step-by-step explanation (ac > b² or b² < ac. )
A/c to question, we have to show:-
b² >ac in A.P ........ (1)
b² = ac in G.P .....(2)
b² < ac in H.P. ..... (3)
b = a+c/2 (A.P)
b = √ac ( G.P)
b = 2ac/a+c (H.P)
In A.P :
b² > ac = b² - ac
= (a+c/2)² - ac
= (a²+2ac+c²/4) - ac = a² + 2ac + c² - 4ac / 4
= a² - 2ac + c² / 4 = ( a - c ) ² / 4 > 0 Hence, b²>ac
In G.P:-
b = √ac
Hence, b² = ac
In H.P :- b² < ac = ac > b² = ac - b² = ac - ( 2ac / a+c)
= ac(a+c) - 2ac / a+c
= a²c + ac² - 2ac / a+c
= ac(2ac - 2) / a+c > 0
Hence, ac > b² or b² < ac.
Which is –3.2 written in the form a/b?
A. -32/100
B. -5/16
C. -3/2
D. -16/5
9514 1404 393
Answer:
D. -16/5
Step-by-step explanation:
-3.2 = -32/10 = -16/5 . . . . matches choice D
_____
More detail
Any finite decimal can be converted to a fraction by considering the place value of the digits.
3.2 = 3×1 + 2×(1/10)
= 3 + 2/10 = (30 +2)/10 = 32/10
Then common factors can be cancelled from numerator and denominator.
32/10 = (2·16)/(2·5) = 16/5
The negative sign can be applied as required.
-3.2 = -(3.2) = -(16/5) = -16/5
Which statement about 2(x+4) is true. Possible answers: :2(x+4) is a quotient :2(x+4)is a product of three factors :2(x+4)has 4 terms. :2(x+4) is a product.
Answer:
[tex]2(x+4)[/tex] is a product
Step-by-step explanation:
Given
[tex]2(x+4)[/tex]
Required
Select a true statement
The expression can be rewritten as:
[tex]2 * (x+4)[/tex]
When we split the expression to 2, we have:
[tex]Term\ 1 = 2[/tex]
[tex]Term\ 1 = x + 4[/tex]
The * between both terms implies that the expression is a product.
And it has 2 terms.

C. Find the value of X. Show your work. Congruent triangles
Answer:
Step-by-step explanation:
1) 97 + x = 64 + 27 {Exterior angle property}
97 + x = 91
x = 91 - 97
x = -6
2) 4x + 17 + 80 + x + 23 = 180 {Angle sum property of triangle}
4x + x + 17 +80 + 23 = 180
5x + 140 = 180
5x = 180 - 140
5x = 40
x = 40/5
x = 8

you are asked to determine which distance is grater, SD or DM given the angle SUD is grater than MUD. using the given information which side is grater. hint a side only has 2 points.
Answer:
Length SD is greater than length DM.
Step-by-step explanation:
We know that the measure of the opposite angle and a side are related, so by determining which angle is bigger, we can discover which side is longer.
Angle SUD is greater than angle MUD. Angle SUD is the opposite angle to SD, and angle MUD is the opposite angle to DM. Therefore, SD is greater than DM.

prove that the equation (a^(2)-5ab)-(7-3ab)+(2ab-a^(2)) is equivilent to -7 please show it step by step! Tysm!
Answer:
Step-by-step explanation:
(a^2 - 5ab) - (7 - 3ab) + (2ab - a^2) = -7
a^2 - 5ab -7 +3ab + 2ab -a^2 = -7 [combine like terms]
a^2 - a^2 = 0
-5ab + 3ab + 2ab = 0
-7 = -7
Answer:
Step-by-step explanation:
you can bring -(7-3ab) to the other side of the equation . then you will have this : (a^2 - 5ab) + (2ab - a^2) = -7 + (7 - 3ab)
now look at this part : -7 + (7 - 3ab) (because adding is a associative procedure) you can get rid of -7 and 7 . then you will have only -3ab
so now this would look like this : (a^2 - 5ab) + (2ab - a^2) = -3ab
now take a look at the left of the equation : just like the last part we can simplify a^2 and - a^2 . and -5ab + 2ab would result in -3ab
because if you subtract -5ab from a^2 and subtract a^2 from 2ab ... then add then to each other would give you the same result
at the end you will have -3ab = -3ab which is a true conclusion.

Which equation is equivalent to S = Ph + 2B?
Answer:
[tex]h = \frac{S - 2B}{P}[/tex]
Step-by-step explanation:
Given
[tex]S=Ph + 2B[/tex]
Required
Select an equivalent expression (see attachment)
[tex]S=Ph + 2B[/tex]
Subtract 2B from both sides
[tex]S - 2B = Ph + 2B - 2B[/tex]
[tex]S - 2B = Ph[/tex]
Divide both sides by P
[tex]\frac{S - 2B}{P} = \frac{Ph}{P}[/tex]
[tex]\frac{S - 2B}{P} = h[/tex]
Reorder
[tex]h = \frac{S - 2B}{P}[/tex] --- Option (b)
The equivalent equation is "[tex]P=\frac{S-2B}{P}[/tex]"
Equation:[tex]\to S= Ph+2B[/tex]
solving the given equation:
[tex]\to S= Ph+2B\\\\\to S-2B= Ph\\\\\to \frac{S-2B}{P}=P\\\\\to P=\frac{S-2B}{P}\\\\[/tex]
Therefore, the final answer of the given equation is "[tex]P=\frac{S-2B}{P}[/tex]".

Step-by-step explanation:
To find the scale factor of a dilation, we first find two corresponding sides. For example, the leftmost side of the black shape corresponds with the leftmost side of the blue shape. The side on the black shape measures 2 units while the side on the blue shape measures 4 units.
Now, we divide the length of the side taken from the figure by the length of the side taken from the original shape.
4/2=2
Therefore, the scale factor of the dilation is 2.

Please solve 8÷ 1/6 with an explanation, any false information or jokes will be reported.
Answer:
48
Step-by-step explanation:
Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes
81×61=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
8×61×1=481
Since 48 divided by 1 equals 48 then,
481=48
Therefore:
81÷16=48

Answer:
58 yards^2
Step-by-step explanation:
You want to break this irregular shape into simple shapes. You can make a rectangle with the sides of 4 and 6 yards, whose are is 24 yards^2.
Then you can do the rectangle on the opposite side, whose sides are 4 and 6 yards, whose are is 24 yards^2 again.
Then the final rectangle has the sides of 5 and 2 yards, whose area is 10 yards^2.
If you add it all up, you will get 58 yards^2.

Keenan is training for a triathlon and needs to swim a certain distance for today's workout. If he swims at the rec center pool, he will complete a 118-yard warmup and then swim laps in a lane that is 41 yards long. If Keenan swims at the indoor pool at his gym, he will complete a 154-yard warmup, plus a main set that consists of 32 yards per lap. If Keenan swims the correct number of laps, he can complete the same distance in either pool. How many laps will that take? How long will Keenan's workout be in total?
9514 1404 393
Answer:
4 laps282 yardsStep-by-step explanation:
For n laps, the length Keenan swims in the rec center pool is ...
118 + 41n
and the length he swims in the gym pool is ...
154 +32n
These are equal length for equal numbers of laps, so we have ...
118 + 41n = 154 + 32n
9n = 36 . . . . . . . . . . . . . subtract 32n+118
n = 4 . . . . . . . . divide by 9
Then the length of Keenan's workout is ...
118 +41(4) = 282 . . . . yards
It will take 4 laps to make the workout total 282 yards in each pool.
