Find x if the base angles of an isosceles triangle are 61 degrees and 7x+19.
The question provides the measures of two angles, (one of which contains
a variable), and the relationship between the angles.
The value of x is 6 degrees
Reason:
The given parameters are;
The base angles of the isosceles triangles are; 61° and (7·x + 19)°
Required:
To find the value of x
Solution:
By definition of an isosceles triangle, we have;
The base angles of an isosceles triangle are equal, therefore;
(7·x + 19) = 61
Which gives;
[tex]x = \dfrac{61 - 19}{7} = 6[/tex]
The value of x = 6

Walmart sells its video games for $42.99. Virginia sales tax is 5%.
A. What is the sales tax for the video game?
B. What would the total price be for the video game?
A) multiply the price of the game by 5%
42.99 x 0.05 = 2.1495 rounds to 2.15
Amount of tax = $2.15
B) add the amount of tax to the price of the game:
42.99 + 2.15 = 45.14
Total cost = $45.14

[tex] \sf k = 1 \\\\ \sf y = x [/tex]
Step-by-step explanation:
A graph between the amount of time that backpacker hikes to the distance travelled is given .
We need to find the constant of proportionality and the equation of the relationship .According to the Question ,
[tex]\sf \implies y \propto x \\\\\sf \implies y = kx [/tex]
Where k is a constant . Now from the graph , when y is 5 x is also 5 . On substituting the numbers ,[tex]\sf\implies 5 = k(5) \\\\\sf \implies k =\dfrac{5}{5}\\\\\sf \implies \boxed{\frak{\pink{ k = 1 }}}[/tex]
Again the constant of proportionality is the slope of the line.
Here the slope of the line is 1 and its y intercept is 0 . On using slope intercept form ,[tex]\sf\implies y = mx + c \\\\\sf \implies y = 1(x) + 0 \\\\\sf \implies \boxed{\pink{\frak{ y = x }}}[/tex]

HELP ASAP!!! 2.) Can you give a real world example of how we use positive and negative numbers? Make sure you can explain the meaning of 0.
Answer and explanation:
Temperature:
If it was -5°C, you know that it is very cold and below freezing point (0°C), but if it was 20°C you know the weather is quite warm.
0°C is freezing point and is used as a reference point to be able to tell if the temperature is warm or not.

Do u think temperature and pressure have any effect on gasses
Answer:
Gay Lussac's Law - states that the pressure of a given amount of gas held at constant volume is directly proportional to the Kelvin temperature. If you heat a gas you give the molecules more energy so they move faster. This means more impacts on the walls of the container and an increase in the pressure.
Step-by-step explanation: An increase in the number of gas molecules in the same volume container increases pressure. A decrease in container volume increases gas pressure. An increase in temperature of a gas in a rigid container increases the pressure
Answer:
yes I think that temperature makes it hotter or
colder depending on the temperature of it or the surroundings and the pressure I don't honestly don't think it effects them

which is an equation of the line with a slope of 1/4 and a y-intercept of -2?
Answer:
y = 1/4x -2
Step-by-step explanation:
If the slope is 1/4, then you must multiply x by 1/4. If we plug 0 into 1/4x, we get 0, but we need -2, so we must subtract 2 in the equation.

Find the equation of the linear function represented by the table below in slope-
intercept form.
Answer:
Hey there, first let's find the slope.
M=y2-y1/x2-x1.
M=7-3/2-1 which is 4/1.
So your slope is 4
So now we have y=4x+b.
Now we need our Y-intercept (B). which is -1
So your answer is Y=4x-1
