The temperature at 6:00p.m. was 7 degrees Celsius. The temperature dropped 2 degrees every hour. What was the temperature at 11:00 p.m.
Answer:
7 Celsius to Fahrenheit is 44.6.
There is a five hour gap.
The tempature drops two degrees per hour. So, multiply.
2 x 5 = 10.
Subtract 10 from 44.6.
You get 34.6.
34.6 is the answer.
A square drawing for a triangular lot measures 6.8 cm by 12.3 cm. The scale is 5 cm: 25 m. Find the area of the parking lot.
5/25 = 6.8/x
5x = 170
x = 34
5/25 = 12.3/x
5x = 307.5
x = 61.5
34(61.5) = 2091 m2

find the values of x and y (2y+5) + (5x-17) +( 3x-11)
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°.
Hope it helps....

9.9 ⋅ 10−28
Answer: I think the answer is 9.9 . 10-28
Answer:
The 7.00 and 10^8 is not in scientific notation because 7.00 can be written as 7 in scientific notation.
Place elementary school is raising money. they raise $90 a week. how long will it take to raise $900?
Answer: It will take 10 weeks! :)
Step-by-step explanation:
So let's look at this together.
The question states that they raise 90$ 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.

Order each set of cards from least to greatest. a. .,⎯⎯⎯⎯√,0.25 , comma , square root of 1 ninth end root , comma , 6 twenty fifths b. ⎯⎯⎯⎯⎯⎯⎯√,.,⎯⎯√square root of 121 over 25 end root , comma , 2.25 , comma square root of 5
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].

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?
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.

1/2(6h – 4) = -5h + 1
Answer: h= 3/8
Step-by-step explanation:
1/2 (6h-4)=-5h+1
distribute
1/2*6h+1/2*-4=-5h-1
3h+-2=-5h+1
add 5h to both sides
8h-2=1
add two to both sides
8h=3
divide both sides by 8
h= 3/8
