Answer:
At 6 pm, the temperature was 13°C below the freezing point
Step-by-step explanation:
Let us first express the information clearly to determine the temperature at 6 p.m:
The temperature in the morning = 6°C
the temperature at noon (12pm) = -13°C
It stayed at that temperature for six hours; this means that the temperature from 12 noon to 6 pm = -13°C
∴ Temperature at 6 pm = -13°C
Next let us calculate how far -13 is, below freezing point (0)
Difference = 0 - (-13)
= 0 + 13 = 13°C
Therefore, at 6 pm, the temperature was 13°C below the freezing point

Find the area of the shape shown below.
Step-by-step explanation:
There are 4 shapes shown in figure i.e Rectangle, Triangle two times and a square .
Dimensions of rectangle length = 9
Breadth = 5
Square = 2
Find the measure of triangle's third side in both .
Find area of all figures then add .
Answer:
42.5 unit²
Step-by-step explanation:
[tex]A_{1}[/tex] = 9 × 3.5 = 31.5
[tex]A_{2}[/tex] = [tex]\frac{2*2}{2}[/tex] = 2
[tex]A_{3}[/tex] = 2² = 4
[tex]A_{4}[/tex] = [tex]\frac{2*5}{2}[/tex] = 5
[tex]A_{1}[/tex] + [tex]A_{2}[/tex] + [tex]A_{3}[/tex] + [tex]A_{4}[/tex] = 42.5 unit²

Change 5x+1=4y+7 to slope intercept form ( y=mx+b)
Answer:
Step-by-step explanation:
5x + 1 = 4y + 7
5x - 4y = 7 - 1
-4y = -5x + 6
-4y/-4 = -5x/-4 + 6/-4
y = 5/4x - 6/4
y = 5/4x - 3/2
Answer:
Work shown below!
Step-by-step explanation:
5x + 1 = 4y + 7 to y = mx + b
5x + 1 = 4y + 7
Subtract 7 from both sides;
5x - 6 = 4y OR 4y = 5x - 6
4y = 5x - 6
Divide both sides by 4;
[tex]y=\frac{5}{4}x-\frac{6}{4} \\\\y=\frac{5}{4}x- \frac{3}{2}[/tex]

In the ASA Congruence Postulate, the side between the angles is called the ___ side.
Marisol is given the following three lengths of a possible triangle: 1, 2 and 7. Would these side lengths form a triangle?
Yes, because 1 + 2 > 7, 2 + 7 > 1 and 7 + 1 > 2.
Yes, because 1 + 2 1 and 7 + 1 is greater than 2.
No, because 1 + 2 < 7 and in order for side lengths to meet the Triangle Inequality Theorem, any two side lengths must be greater than the third side when added together.
Answer:
no because 1+2<7. To form a triangle any two lengths have to be greater than third one

A 0.450 L sample of nitrogen gas is collected under a pressure of 2.30 atm and a temperature of 60.0 degrees Celsius. The sample is transferred to a 0.600 L container and the pressure drops to 1.54 atm. What is the new temperature of this gas (in K)?
Answer:
326.56KStep-by-step explanation:
Step one:
Given
V1=0.45L
P1=2.3atm
T1=60 °
V2=0.6L
P2=1.54atm
T2=?
Step two:
Required:
T2
Applying the partial gas formula
[tex]\frac{P1V1}{T1}=\frac{P2V2}{T2}[/tex]
[tex]\frac{2.3*0.45}{60}=\frac{1.54*0.6}{T2}[/tex]
cross multiply we have
T2=(1.54*0.6*60)/2.3*0.45
T2=55.44/1.035
T2=53.56 °
in kelvin, we need to add 273
=273+53.56=326.56K
T2=326.56K
The new temperature of this gas (in K) is 326.56K

What is the value of x in the question 1/2(x+6)=18
Answer: x= 30
Step-by-step explanation:
Simplify both sides of the equation. 12(x+6)=18(12)(x)+(12)(6)=18(Distribute) 1x+3=18
Step 2: Subtract 3 from both sides. 12 x+3−3=18−312 x=15
Step 3: Multiply both sides by 2. 2*(12x)=(2)*(15)
