Serena wants to create snack bags for a trip she is going on. She has 6 granola bars and 10 pieces of dried fruit. If the snack bags should be identified without any food leftover, what is the greatest number of snack bags Serena can make?

Answers

Answer:

2

Step-by-step explanation:

Given the question :

Serena wants to create snack bags for a trip she is going on. She has 6 granola bars and 10 pieces of dried fruit. If the snack bags should be identified without any food leftover, what is the greatest number of snack bags Serena can make?

Number of granolas = 6

Number of dried fruits = 10

Since the snackbag is to be designed in such a way that there should be no food leftover, the greatest number of snack bags Serena can make could be obtained by getting the highest common factor of (6 and 10)

____6____10

2___3____5

Here, the highest common factor of 6 and 10 is 2

Hence, the greatest number of snack bags she can make is 2.

Place elementary school is raising money. they raise $90 a week. how long will it take to raise $900?

Answers

Answer: It will take 10 weeks! :)

Step-by-step explanation:

So let's look at this together.

The question states that they raise 90$ per week.

There's two ways you can do this

You can multiply,

Think, what times 90 will equal 900? The answer is 10!

90 x 10= 900!

(if you need help with multiplication, let me know)

Or you can divide.

900/90=10!

(if you need help with division, let me know)

So it would take, in total, 10 weeks to raise 900 dollars.

find the values of x and y (2y+5) + (5x-17) +( 3x-11)

Answers

Step-by-step explanation:

Hey there!!

You can simply work with it.

(5x - 17)° + (3x - 11)° = 180° { Being a linear pair}.

or, 8x - 28°= 180°

8x = 180° + 28°

[tex]x = \frac{208}{8} [/tex]

Therefore, the value of x is 26°.

Now,

3x - 11°= 3×26°-11° = 67°

Again,

67°+90°+(2y+5)° = 180° { being linear pair}.

157°+2y+5° = 180°

or, 2y + 162° = 180°

or, 2y = 180° - 162°

[tex]y = \frac{18}{2} [/tex]

Therefore, the value of y is 9°.

The value of x is 26° and y is 9°.

Mary's car can go 24 miles on one gallon of gasoline. However , her gas mileage can vary by 2 miles per gallon depending on where she drives . Write an absolute value equation that you can use to find the minimum and maximum gas mileage.

Answers

Answer: | x -24 |=2

Step-by-step explanation:

Given: Mary's car can go 24 miles on one gallon of gasoline.

her gas mileage can vary by 2 miles per gallon depending on where she drives .

i.e. either 2 miles added or subtracted in the  gas mileage.

i.e. -2< Gas milegae -24 <2

⇒  | Gas milegae -24 |=2

Let x represents the gas mileage.

Then,  | x -24 |=2 is the required absolute value equation that you can use to find the minimum and maximum gas mileage.

1/2 (6h-4)=-5h+1

distribute

1/2*6h+1/2*-4=-5h-1

3h+-2=-5h+1

8h-2=1

Answers

Given:

a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

To find:

The correct order for each set of cards from least to greatest.

Solution:

a. [tex]\sqrt{0.25},\sqrt{\dfrac{1}{9}},\dfrac{6}{25}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{0.25}=0.5[/tex]

[tex]\sqrt{\dfrac{1}{9}}=\dfrac{1}{3}=0.333...[/tex]

[tex]\dfrac{6}{25}=0.24[/tex]

It is clear that,

[tex]0.24<0.33...<0.5[/tex]

[tex]\dfrac{6}{25}<\sqrt{\dfrac{1}{9}}<\sqrt{0.25}[/tex]

Therefore, the required order is [tex]\dfrac{6}{25},\sqrt{\dfrac{1}{9}},\sqrt{0.25}[/tex].

b. [tex]\sqrt{\dfrac{121}{25}},2.25,\sqrt{5}[/tex]

Convert all numbers in decimal form.

[tex]\sqrt{\dfrac{121}{25}}=\dfrac{11}{5}=2.2[/tex]

[tex]2.25[/tex] already in decimal form.

[tex]\sqrt{5}\approx 2.236[/tex]

It is clear that,

[tex]2.2<2.236<2.25[/tex]

[tex]\sqrt{\dfrac{121}{25}}<\sqrt{5}<2.25[/tex]

Therefore, the required order is [tex]\sqrt{\dfrac{121}{25}},\sqrt{5},2.25[/tex].
