Answers

Answer 1

Answer:

The first one.

Step-by-step explanation:

solving for x:

5/2 = 7.5/x

cross multiply

2 ×7.5 =5x

x= 2×7.5/5

x= 3

solving for y:

values of the small triangle over the bigger triangle-

5/6 =7/y

cross multiply and solve for y

y= 8.4

therefore (x= 3; y= 8.4)

you need to use "PRT"( Principal× Rate×time) but since it doesn't give us the time, we'll be only doing principal×rate. just multiply 596 and 40% And don't forget to put the percent sign bc it would change the price!! and I hope that helps u

Find the value of BC

Answers

Answer: BC=3

Step-by-step explanation: Set the two side lengths equal to each other and solve.

Answer:

BC = 20 units.

Step-by-step explanation:

This triangle has 3 equal sides.

so: -y + 23 = 6y + 2

23 - 2 = 6y + y

21 = 7y

y = 3.

So each side is 6(3) + 2 = 20 units long.

Solve for w,x,y and z

Answers

Answer:

Step-by-step explanation:

2y - 6 + y = 180   {Co-interior angles}

3y - 6   = 180

      3y = 180 + 6

     3y = 186

       y = 186/3

       y = 62

y + w = 180     {Linear pair}

62 +w = 180

       w = 180 - 62

        w = 118

ΔILK ,

∠L +  ∠ I + ∠K = 180  {Angle sum property of triangle}

w + z + 30 = 180

118 + z + 30 = 180

     z +  148  = 180

               z =180-  148

                z = 32

x = z    {Alternate interior angles}

x = 32

how to solve improper fraction of 4/5 - 1/4???

Answers

they aren’t improper tho?
4/5 - 1/4
find a common denominator
it would be 20
4/20 - 1/20
change the numerator too
16/20 - 5/20
it would give you 11/20

Answer:

11/20

Step-by-step explanation:

First, you have to find a common denominator between the two fractions, 4 and 5 can both equal 20 so we change the denominators to 20, 4/5 =16/20 since whatever we multiply on the bottom we multiply on the top, now for 1/4 we change it to 5/20. Now for the question, we subtract since that's what it's asking, so 16/20 - 5/20, 16 - 5 equals 11 and the denominators stay the same so the answer would be 11/20

help me solve for t please

Answers

Answer:

t = 1/3

Step-by-step explanation:

for this problem we have two different shapes, what we need to do is find out the proportional relationship between the two to solve for t, lets take one of the measurements from the smaller shape, we will go with... JK at 5

now all we need to do is divide that by the larger shapes same side, in this case that would be RP at 22.5, heres what that looks like so far

5 / 22.5 = 0.2-> (the two goes on forever, normally this is represented by a line above the infinite number, this is what they call a Repeating Decimal)

ok, so now that we have the rate of change between the two shapes figured out, now we just make the same change to the last side from the same side on the first shape, wich is LK to QR as shown

1.5 * 0.2-> = 0.3->

and if 0.3 is = to 1/3, so t = 1/3

i hope this helped you out, im sorry if im a little late lol, make note that all of this can be applied to similar situations, just figure out the change(s) that happened from one shape to the other, and make that same change on the unknown side or area

take care :D

If a1=10 and an=an-1+4 then find the value of a5

Answers

Answer:

26

Step-by-step explanation:

Each term is the previous with 4 added to it.

a1 = 10, a2 = 14, a3 = 18, a4 = 22, a5 = 26

The value of [tex]a_{5}[/tex] will be equal to 26 .

It is given that [tex]a_{1}[/tex]= 10 and [tex]a_{n} = a_{n-1} + 4[/tex].

We have to find the value of [tex]a_{5}[/tex].

What do you mean by sequences ?

Sequences are a list of numbers which are arranged in a special manner i.e., 2 , 4 , 6 , 8 numbers of this sequence gets increased by 2 every time.

As per the question ;

The first term ;  [tex]a_{1}[/tex]= 10

and given ;

[tex]a_{n} = a_{n-1} + 4[/tex]

So ;

2nd term will be ;

[tex]a_{2} = a_{1} + 4[/tex]

[tex]a_{2}[/tex] = 10 + 4

or

[tex]a_{2}[/tex] = 14

Now ;

3rd term will be ;

[tex]a_{3} = a_{2} + 4[/tex]

[tex]a_{3} = 14 + 4[/tex]

[tex]a_{3}[/tex] = 18  

Hence , the common difference is d = 4.

So ;

4th term will be ;

[tex]a_{4}[/tex] = 18 + 4

[tex]a_{4}[/tex] = 22

and

5th term will be ;

[tex]a_{5}[/tex] = 22 + 4

[tex]a_{5}[/tex] = 26

Thus , the value of [tex]a_{5}[/tex] will be equal to 26 .

Drag a graph to each category based on the slope of the graph.

Answers

Answer:

hope this helps!!...the last one is the last box that's at the top

Step-by-step explanation:

The slope of a graph is the rate of change of the graph

Graphs 3 has a slope greater than 1Graph 2 has a slope less than 0Graph 4 has a slope equal to 0

When the y values of a graph with the x values, the graph will have a positive slope.

From the figures, graph 3 follows the above highlight.

Hence, graph 3 has a slope that is greater than 1

When the y values of a graph decreases, as the x values increases, the graph will have a negative slope.

From the figures, graph 2 follow the above highlight.

Hence, graph 2 has a slope that is less than 0

A graph with a horizontal line will have its slope to be 0.

Hence, graph 4 has a slope equal to 0
