Answer:

s would equal 13

Step-by-step explanation:

Hello there!

So to find the value of s when q=1 we just have to plug in 1 into q into the expression s=5q+8

so when q=1

s=5(1)+8

5*1=5

5+8=13

so we can conclude that when q=1 s=13

Answer:

13

Step-by-step explanation:

s = 5q + 8

s = 5(1) + 8

s = 5 + 8

s = 13

Answer:

the height of the cross section is 3 feet

Step-by-step explanation:

The computation of the height of the cross section is shown below:

Area = 1 ÷ 2 × (a + b) × h

39 = 1 ÷ 2 × (20 + 6) × h

39 =  1 ÷2 × 26 × h

39  = 26 ÷ 2 × h

39 = 13 × h

h = 39 ÷ 13

= 3 feet

hence, the height of the cross section is 3 feet

Answer:

The next year population is 122,689

Step-by-step explanation:

The computation of the next year population is as follows:

= This year population × increase percentage

= 119,000 × (1 + 0.031)

= 119,000 × 1.031

= 122,689

Hence, the  next year population is 122,689

The above formula is applied so that the correct value of the population could come

Answer:

y=-4x+2

and

x= y-2/-4

Step-by-step explanation:

you have y,

y= -4x+2

to solve for x, follow this...

y = -4 x + 2

-2           -2

y - 2 = -4 x

/-4         /-4

x= y-2/-4

Answer: [tex]1,00,000(1+0.042)^x[/tex]

Step-by-step explanation:

Given

The initial population of a city is [tex]P_o=1,00,000[/tex]

The annual growth rate is [tex]4.2\%[/tex]

after 1 year it is

[tex]\Rightarrow P_1=1,00,000+4.2\%\times 1,00,000\\\Rightarrow P_1=1,00,000(1+0.042)[/tex]

after 2 years, it is

[tex]\Rightarrow 1,00,000(1+0.042)+4.2\%\times 1,00,000(1+0.042)\\\Rightarrow 1,00,000(1+0.042)^2[/tex]

after x years it is

Answer:

$57

Step-by-step explanation:

→ Do 20% of $80

( 20 × 80 ) ÷ 100 = 16

→ Add 5 to the previous answer

5 + 16 = 21

→ Add 2 to 21

2 + 21 = 23

→ Minus 23 from the total price

80 - 23 = $57

Answer:

6 inches = 152.4 mm

Step-by-step explanation:

Answer:

Step-by-step explanation:

Let n = the smaller of the two numbers, and since the other number is 5 more than twice the smaller number n, then ...

Let 2n + 5 = the second and larger number.

Since the sum of the two unknown numbers is 26, then we can write the following equation to be solved for n as follows:

n + (2n + 5) = 26

n + 2n + 5 = 26

Collecting like-terms on the left, we get:

3n + 5 = 26

3n + 5 - 5 = 26 - 5

3n + 0 = 21

3n = 21

(3n)/3 = 21/3

(3/3)n = 21/3

(1)n = 7

n = 7

Therefore, ...

2n + 5 = 2(7) + 5

= 14 + 5

= 19

CHECK:

n + (2n + 5) = 26

7 + (19) = 26

7 + 19 = 26

26 = 26

Therefore, the two desired numbers whose sum is 26 are indeed 7 and 19.

Answer:

The answer is 7 and 19

Answer:

Answer: $15

Step-by-step explanation:

Jasmine needs 300 centimeters

$5 each meter

The first step you need to do is convert 300 centimeters to meters, because it’s $5 for each meter.

(You can use the King Henry Chart to help you)

So, 1 centimeter is 1/100 meter

How much is 300 centimeters in meters?

300x1/100

= 300/100

=3

300 cm= 3m

Now, there is $5 for each meter.

How much does it cost for 3 meters?

= 5x3

= $15

It will cost her $15

F.

Step-by-step explanation:

Everything has to be less than 4 which leaves us with C and F, but Fs dot is shaded in which means it is less than or equal to but it is only less than so it is F.

Answer:

F

Step-by-step explanation:

If you look x is less than 4 meaning that all values are lower than 4. We also know that 4 is not included due to the fact that the less than symbol doesn't have a line under it. F is the only line that meets all of the criteria.

Answer: 70

Step-by-step explanation:

Answer:

12.01 sticks of satay

Step-by-step explanation:

Let

Total satay bought = x

Eldest child ate = 1/6x

Youngest child ate = 0.25x

Total = 1/6x + 0.25x

= 0.167x + 0.25x

= 0.417x

Remaining satay = x - 0.417x

= 0.583x

The rest of the satay was shared equally between her other 2 children where each person ate 14 sticks of satay.

Her and her other two children = 3 people

Sticks of satay pee person = 14

Total sticks eaten by 3 people = 14 × 3

= 42 sticks

0.583x = 42

x = 42/0.583

= 72.04

x = 72.04 sticks

Total satay bought = x = 72.04 sticks

Eldest child ate = 1/6x

= 1/6 * 72.04

= 12.01 sticks of satay

Answer:

-2b(a) - a^2 -2b^2

Step-by-step explanation:

Just use the 'foil' method, meaning that you multiply the first number of one part (a), to the first and second to the next part (2b, -a)

Then, multiply the second number of that part (-b), to the first and to the next part (2b, -a)

You would get: -2b(a) - a^2 -2b^2

Multiplication is the process of multiplying. The multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².

Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.

An expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context. The multiplication of the two given expressions (a-b) and (2b-a) can be done as shown below,

(a-b) × (2b-a)

= a(2b-a) -b(2b-a)

= (a × 2b) - (a × a) - (b × 2b) + (b × a)

= 2ab - a² - 2b² + ab

=  -a² -2b² + 3ab

= 3ab -a² -2b²

Hence, the multiplication of (a-b) by (2b-a) results in 3ab-a²-2b².
