| - 6 - 10 | = | - 16 | = 16 , or
| 10 - (- 6) | = | 10 + 6 | = | 16 | = 16
Which theorem can be used to show that △JKL ~ △MNP?
In this case the answer would be the last option
because it is shrunk by 2/3 on just the x side
D is the only one who has that first transformation
By a theorem of similarity, it can be shown that △JKL ~ △MNP.
What is the similarity?Similar figures are those figures which are identical in shape, but not necessarily in size.
Two squares with sides of 10 and 5 are similar because their shape is exact but the size is different.
Another example is all circles are similar circles.
The ratio of corresponding sides of similar objects is always the same.
Any two triangles will be similar if the ratio of their corresponding side is same.
If △JKL ~ △MNP then their corresponding side ratio will definitely same.
If corresponding side is same order in JKL and MNP then,
JK/KL = MN/NP
Hence "By a theorem of similarity, it can be shown that △JKL ~ △MNP".

Step-by-step explanation:
Given: 16 = -4(x - 1) + 4
Solution:
Subtract 4 from both sides
12 = -4(x -1)
Divide -4 on both sides
-3 = x - 1
Add -1 on both sides

Jessie made 3 shots out of 4 tries, how many shots will she make if she tries 12 shots (use a proportion
Answer:
10 out of 12 which is [tex]\frac{5}{6}[/tex] when simplified
Answer:
9:12
Step-by-step explanation:
3:4 is the ratio of her shots to tries
x:12 is the ratio we want to find, so you can turn these into fractions: 3/4 to x/12
to find x you figure out what you multiply 4 by to get to 12, which is 3, so you multiply 3 by 3 and you get 9
so the answer is 9:12

In parallelogram RELA you are given that the measure of angle R = 110 degrees. Find the measure of angle E?
Help me solve thiss
Answer:
Angle E = 70°
Step-by-step explanation:
Given parallelogram RELA, where m<R = 110°, to find m<E, recall the properties of a parallelogram.
Angle R and angle E are consecutive angles in parallelogram RELA.
One of the properties of a parallelogram states that any 2 consecutive angles in a parallelogram are supplementary. That is, they add up to 180°.
Therefore:
m<R + m<E = 180°
110° + m<E = 180°
Subtract 110° from both sides
m<E = 180° - 110° = 70°

$6.00 to 95 cents =
Answer:
$6.00 to 95 cents = $6.95
Step-by-step explanation:
In currency the dollar is a whole number while the cent is a fraction of the dollar.
For the cent, every 100 cent is a dollar.
Converting the cent to dollar
100 cent = $1k
K= 100/1
95 cent = 100/1 x
95/100= x
0.95$= x
$6.00 to 95 cents = $(6+0.95)
$6.00 to 95 cents = $6.95
Ava is in charge of bringing bottled water to a party that has 42 guests.
Bottled water is sold in packs of 18 and each pack costs $16.92.
Part A: enter the total number of packs of water Ava will need to bring to the party if each guest is to have 1 bottle of water.
Part B: enter the total cost, in dollars, Ava will spend on bottled water for the party.
Answer:
a - about 3 packs cause you have to round up
b - $50.76
Step-by-step explanation:
First you divide 42 and 18.
42/18=2.33
You have to round up cause you can't have half of a pack, you can't just buy half of a pack.
So, it is rounded to 3 packs.
Next you have to multiply the number of packs and the cost of each pack of water bottles.
16.92*3=$50.76
a - you have to buy 3 packs
b - the total cost is $50.76

Answer:
Yes, it is possible.
Step-by-step explanation:

Given the acceleration, initial velocity, and initial position of a body moving along a coordinate line at time t, find the body's position at time t. a=16, v(0) = -14, s(0) = -8
Answer:
The position at time t is [tex]s(t) = 8t^2 - 14t -8[/tex]
Step-by-step explanation:
From the question we are told that
The acceleration is [tex]a = 16[/tex]
The velocity at t = 0 is [tex]v(0) = -14[/tex]
The position at time t = 0 is [tex]s(0) = -8[/tex]
Generally acceleration is mathematically represented as
[tex]a(t) = \frac{d v}{dt }[/tex]
=> [tex]\frac{dv}{dt} = 16[/tex]
=> [tex]dv = 16 dt[/tex]
integrating both sides we have
[tex]\int\limits dv = \int\limits16 dt[/tex]
=> [tex]v(t) = 16 t + c[/tex]
Now at t = 0
[tex]v(0) = 16 * 0 +c = -14[/tex]
=> [tex]c = -14[/tex]
So
[tex]v(t) = 16 t -14[/tex]
Generally the position of the body is mathematically represented as
[tex]s(t) = \int\limits v(t)dt[/tex]
So
[tex]s(t) = \int\limits 16t - 14 dt[/tex]
So
[tex]s(t) = 16 \frac{t^2}{2} - 14t + C[/tex]
Now at t = 0
[tex]s(0) = 16 \frac{0^2}{2} - 14(0) + C = -8[/tex]
=> [tex]C = -8[/tex]
So
[tex]s(t) = 8t^2 - 14t -8[/tex]
Rate of change of velocity with respect to time is known as acceleration.
Rate of change of displacement with respect to time is known as velocity.
Body position at time t is given by, [tex]s(t)=8t^{2}-14t-8[/tex]
Data given are, a=16, v(0) = -14, s(0) = -8
Since, [tex]\frac{dv}{dt}=a\\\\\frac{dv}{dt}=16\\\\dv=16dt[/tex]
Integrating both side
We get, [tex]v=16t + C[/tex]
Substituting v(0)=-14 in above equation
We get, C = -14
So, [tex]v=16t-14[/tex]
Since, Rate of change of displacement with respect to time is known as velocity.
[tex]v=\frac{ds}{dt}\\\\ds=vdt\\\\ds=(16t-14)dt[/tex]
Taking integration on both side
We get, [tex]s=16\frac{t^{2} }{2}-14t+c[/tex]
Substituting s(0)= - 8 in above equation
We get, [tex]c=-8[/tex]
So, [tex]s=16\frac{t^{2} }{2}-14t-8\\\\s(t)=8t^{2} -14t-8\\[/tex]
