Answer:

$x=\frac{s}{q+r}$

Step-by-step explanation:

1 Factor out the common term x

$x(q+r)=s$

2 Divide both sides by q+r

$x=\frac{s}{q+r}$

Fred’s company is planning a new logo. The diagrams show two similar versions of the planned logo.

seraphim [82]

Answer:

a=7.2*1.5=10.8 cm

b=6.3/1.5=4.2 cm

$\pounds 4.48*2.25=\pounds 10.08$

Step-by-step explanation:

<u>Proportional Geometric Shapes </u>

A) We are given two similar shapes of a logo. They are to be proportional. We only need to find the proportion ratio of two of them to find the rest of the lengths.

The upper sides have 7.5 cm and 5 cm respectively. This gives us the ratio

$\displaystyle r=\frac{7.5}{5}=1.5$

Which means all the measures of the smaller logo are 1.5 smaller than those of the larger. This means

b=6.3/1.5=4.2 cm

a=7.2*1.5=10.8 cm

B) To paint the logos, we need to cover its surface, so the ratio of the surface is 1.5*1.5=2.25

This means the cost to paint the larger logo is

$\pounds 4.48*2.25=\pounds 10.08$

Determine whether set B is a subset of A.<br> 7. A = {2, 3, 5, 7, 11}<br> B = {3, 5, 7, 9, 11)

VARVARA [1.3K]

Answer:

Set B is not a subset of A.

Step-by-step explanation:

If there are sets, A and B with some elements, then B can be called subset of A, if every element of B is present in set A.

Example.

Example

A is set of integers

B is set of natural numbers

we know set of integers is all the negative numbers, 0 and all the positive discrete numbers like

A = {......-3,-2,-1,0,1,2,3,4........}

B is set of positive discrete numbers from 1 to infinity)

B = {1,2,3,4........}

Thus, we see every element of B is present in A . Hence B is subset of A

___________________________________________

Given

A = {2, 3, 5, 7, 11}

B = {3, 5, 7, 9, 11)

Here,

In set B . elements 3,5,7,11 are present in set A, but

Element 9 from set B is missing Set A.

Since, every element of Set B is not present in set A hence

Set B is not a subset of A.
