Find the distance between riverside and Milton if they are 12cm apart on a map with a scale of 4cm :21km

Answers

Answer 1

Answer: since 4 cm is 21 km
12 cm is 63 km apart

Answer 2

Answer: The answer would be 63km.

I got this by saying:

For every 4cm, there are 21km.

There are 3 sets of 4cm in 12cm.

3*4=12
21*3=63

Rule: add 15, subtract 10 first term 4

Answers

The order for the given rule is 4, 19, and 9 if the rule is to add 15 and deduct 10 from the first term.

What is a sequence?

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

Divergent sequences are those in which the terms never stabilize; instead, they constantly increase or decrease as n approaches infinity, approaching either infinity or -infinity.

It is given that, the rule of the sequence is to add 15, subtract 10 first term 4,

We have to apply the arithmeticoperation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.

If the first term is 4 add 15 first and subtract 10 from it,

=4 + 15

=19

=19-10

Thus, the order for the given rule is 4, 19, and 9 if the rule is to add 15 and deduct 10 from the first term.

Line segment AB has endpoints A(2, 9) and B(5, 8) . A dilation, centered at the origin, is applied to AB¯¯¯¯¯ . The image has endpoints A′(43, 6) and B′(103, 163) . What is the scale factor of this dilation? 32

Answer: The correct option is (B) $(2)/(3).$

Step-by-step explanation: Given that the co-ordinates of the end-points of a line segment AB are A(2, 9) and B(5, 8). After being dilated about the origin (0, 0), the co-ordinates of the end-points of image A'B' are $A^\prime\left((4)/(3),6\right)$ and $B^\prime\left((10)/(3),(16)/(3)\right).$

We are to find the scale factor of the dilation.

The scale factor of the dilation will be

$S=\frac{\textup{length of the image line}}{\textup{length of the original line}}.$

The lengths of the lines AB and A'B' are calculated using distance formula as follows:

$AB=√((5-2)^2+(8-9)^2)=√(9+1)=√(10),\n\n\nA'B'=\sqrt{\left((10)/(3)-(4)/(3)\right)^2+\left((16)/(3)-6\right)^2\right)}=\sqrt{4+(4)/(9)}=\sqrt{(40)/(9)}=(2)/(3)√(10)~\textup{units}.$

Therefore, the required scale factor of dilation is

$S=(A'B')/(AB)=((2)/(3)√(10))/(√(10))=(2)/(3).$

Thus, the scale factor of the dilation is $(2)/(3).$

Option (B) is CORRECT.

the answer is 2/3

Norma bought 1 3/4 yards of cotton fabric and 3 3/8yards of fleece fabric. How many yards of fabric did Norma buy?

Answers

1 3/4 = 1 6/8

1 6/8 + 3 3/8 = 4 9/8

4 9/8 = 5 1/8

Norma bought 5 1/8 yards of fabric.

First you need to turn 1 3/4 into an improper fraction.
1 3/4= 7/4
Then multiply 7/4 by 2 which is 14/8
Then add
