The angles of a triangle are in an extended ratio of 5:7:3. What is the measure of the
largest angle?
Answer:
84°
Step-by-step explanation:
Let the measures of the triangle be 5x, 7x, 3x.
By interior angle sum postulate of a triangle.
5x + 7x + 3x = 180°
15x = 180°
x = 180°/15
x = 12°
7x = 7*12°= 84°
Measure of the largest angle = 84°
A girl was asked to multiply a number by 7/8.instead she divided the number by 7/8and got the result 15 more than the correct result.what is the number
Answer:
x=56
Step-by-step explanation:
number = x
7/8x=8/7x-15
Add 15
15+7/8x=8/7x
Subtract 7/8
15=15/56x
x=56
The number is 56

When 0.3(4x – 8) – 0.5(–2.4x + 4) is simplified, what is the resulting expression?
A. -4.4
B. 1.2x - 2.4 + 1.2x - 2
C. 2.4x - 0.4
D. 2.4x - 4.4
Answer:
It's the B
Step-by-step explanation:
0.3*4=1.2
0.3 *(-8)=-2.4
-0.5*(-2.4x)= 1.2x
-0.5*4=-2
So it's 1.2x - 2.4 + 1.2x - 2

Brianna is getting materials for a chemistry experiment. Her teacher gives her a container that has 0.25 liter of a liquid in it. Brianna needs to use 0.4 of this liquid for the experiment. How much liquid will Brianna use?
Answer: 0.1 liter
Step-by-step explanation:
From the question, we are informed that Brianna teacher gives her a container that has 0.25 liter of a liquid in it and she needs to use 0.4 of this liquid for the experiment.
The amount of liquid that Brianna will use will be:
= 0.4 × 0.25 liters
= 0.1 liter

Will give reward if right
Answer:
J = 7.5
Step-by-step explanation:
* This is going off of the estimate that the = sign means the equation is = to 0, as there is no value after the equal sign. *
First, start off by adding all of the like numbers.
11 + (-3) + 7 = 8 + 7 = 15
- 1/8 j - 3/8 j = - 4/8 j.
Combining those two sums, we get:
15 - 4/8 j = 0
Subtract 15 from both sides,
-4/8 j = -15
Simplify -4/8 to -1/2, and then to -0.5
-0.5j = -15
Divide.
-15/-0.5 = 7.5
When you divide a negative number by another negative number, you get a positive. Therefore, the answer is J = 7.5
If the number after the = sign IS NOT 0, then when you get to 15 - 0.5j, just do the steps but with a number that isn't 0.

(-4, -7) and (-6, 9) in slope-intercept form. Show work
Answer:
Equation of line in slope-intercept form is: y = -8x-39
Step-by-step explanation:
Given points are:
(-4, -7) and (-6, 9)
The slope-intercept form is given by the equation
[tex]y = mx+b[/tex]
Here m is the slope of the line and b is the y-intercept.
m is found using the formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
Here
(x1,y1) = (-4-7)
(x2,y2) = (-6,9)
Putting the values in the formula
[tex]m = \frac{9+7}{-6+4} = \frac{16}{-2} = -8[/tex]
Putting slope in general equation
[tex]y = -8x+b[/tex]
Putting (-6,9) in the equation
[tex]9 = -8(-6)+b\\9 = 48+b\\b = 9-48\\b = -39[/tex]
Putting the value of b we get
[tex]y = -8x-39[/tex]
Hence,
Equation of line in slope-intercept form is: y = -8x-39
