6) 98=4b+ 2c; Find b if c=5

Answer:

2nd term = 11

5th term = 74

Step-by-step explanation:

3n² - 1

n = 2 , 2nd term = 3*2²  - 1

                           = 3*4 -1

                          = 12 - 1

                          = 11

n= 5 , 5th term = 3*5² - 1

                        = 3*25 - 1

                      = 75 - 1

                      = 74

Step-by-step explanation:

rectangle.

rhombus.

square.

Answer:

a smaller version of the shape think :)

Answer: See explanation

Step-by-step explanation:

1.) There's an angle supplementary to m∠123°, that angle is y

y and m∠123° are supplementary since they're linear pairs

y + 123 = 180

Subtract both sides by 123

y = 57°

Now we know at least two angles of the triangle, x + y + m∠92° has to be 180° because they form a triangle.

x + y + m∠92° = 180°

x + 57 + 92 = 180

x + 149 = 180

Subtract both sides by 149

x = 31°

2.) We have to figure out the missing angle in the triangle, that missing angle is once again, y.

y + 100 + 25 = 180

y + 125 = 180

y = 55°

x and y are supplementary angles because they form a straight line

x + y = 180°

x + 55 = 180

Subtract both sides by 55

x = 125°

Answer:

10.84

Step-by-step explanation:

First we multiply

1.4+(3.2×2.95)

1.4+9.44=

=10.84

Answer:

3.06

Step-by-step explanation:

Answer:

You will get $3.06 back

Step-by-step explanation:

Add 5.97 + 5.97 = 11.94

then if you give the cashier $15 subtract what you owe, so 15 - 11.94 = 3.06

Answer:

C. The mean increases by 0.75.

Step-by-step explanation:

The mean of a data set is given by the sum of all its values, divided by the number of values.

Data set {10, 2, 8, 9, 5, 2, 6}

7 values

Sum: 10 + 2 + 8 + 9 + 5 + 2 + 6 = 42

Mean: 42/7 = 6

Adding number 12 to the data set

Now we have 8 values

The sum is 42 + 12 = 54

The mean is 54/8 = 6.75

This means that the mean increases by 0.75.

Answer:

C. 7.5

Step-by-step explanation:

the mean increases by it

Answer:

20 m

Step-by-step explanation:

Given that :

Scale of 1 : 50 is used to make a model

If the model has a height of 40 cm ; the height of the house is:

Then, the actual height of the house is (40 * 50) = 2000 cm

Thus the height of the house in metre is :

100cm = 1 meter

2000 cm = 2000 / 100

2000 cm = 20 meter

Height of house in meter = 20 meter

Answer:

true

Answer:

True

Step-by-step explanation:

The area of a rectangle is A=lw.

If l=8 and w=12, then 8(12) = 96

Your units will be 96 sq. m, so the answer is True

Answer:

the slope is 95

Step-by-step explanation:

to find the slope of the line divide the change in y by the change in x

if x is minutes and y is meters

Answer:

UY = 90

GH = 4

Step-by-step explanation:

Since both figures are similar, the ratio of their corresponding side lengths would be the same.

Thus:

✔️UY/GF = XW/IJ

UY/10 = 54/6 (Substitution)

Multiply both side by 10

UY = (54*10)/6

UY = 90

✔️Also,

UV/GH = XW/IJ

36/GH = 54/6

36/GH = 9

GH = 36/9

GH = 4

Answer: Its the very last one

Step-by-step explanation: first you need to divide the 6 by the 15 and then add it by how many friends your going to share it with

Answer:20

Step-by-step explanation:m =2 So you plug in 2 as m now which means  you do 12 times 2 which gives you 24.Lastly do 24 subtract 4 which gives you 20 .

Hope it helps :)
