[tex]-\frac{35}{18}[/tex]
Step-by-step explanation:
[tex]\frac{5}{3}[/tex] ÷ [tex]-\frac{6}{7}[/tex] is the same as [tex]\frac{5}{3}[/tex] × [tex]-\frac{7}{6}[/tex]
Multiply across:
5 x 7 = 35
3 x 6 = 18
Applying the negative sign, we get:
[tex]-\frac{35}{18}[/tex]
Since we cannot simplify any further, -35/18 is out final answer.

A scale drawing of Jack's living room is shown below: A rectangle is shown. The length of the rectangle is labeled as length equal to 6 cm, and the width is labeled as width equal to 4 cm. If each 1 cm on the scale drawing equals 5 feet, what are the actual dimensions of the room? (5 points) Length = 11 feet, width = 9 feet Length = 30 feet, width = 20 feet Length = 8 feet, width = 12 feet Length = 22 feet, width = 20 feet
Answer:
(b) Length = 30 feet, width = 20 feet
Step-by-step explanation:
The scale factor is applied to the drawing dimensions to find the actual dimensions.
__
length = (6 cm) × (5 ft)/(1 cm) = 30 ft
width = (4 cm) × (5 ft)/(1 cm) = 20 ft
_____
Additional comment
You can also write the scale factor as part of a proportion:
5 ft : 1 cm :: x ft : 6 cm
Multiplying by 6 cm gives
(5 ft)(6 cm)/(1 cm) = x ft = 30 ft . . . . as above

If P and Q are points on a circle, then the center of the circle must be on the perpendicular bisector of chord P Q. Explain. Which point on the chord is closest to the center? Why?
The center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center.
What is a perpendicular bisector?It should be noted that a perpendicular bisector simply means a line the intersect another line through the intersection point.
In this case, the center of the circle must be on the perpendicular bisector of chord PQ since it passes through the center. This bisects it at a right angle. The chord closer to the centimeter will be the one closer to the diameter.

A force of 61 N is applied to an area of 750 cm2.
Calculate the pressure in N/m2.
Give your answer to the nearest integer.
Step-by-step explanation:
Area750 cm² = 750 × 10^-4 m²
pressure = F/A
= 61 /(750×10^-4)
= 61 × 10⁴/750
= 0.081 × 10⁴
= 810 N/ m²
Answer:
813N/m^2
Step-by-step explanation:
Pressure is defined as the amount of force applied to an area. There are 100cm in a single meter, therefore:
[tex]750cm^2=\sqrt{750} cm\frac{1}{100} \frac{m}{cm} =\frac{\sqrt{750} }{100} m=0.075m^2[/tex]

Graph the line with slope 3/2 and y-intercept 3.
Answer:
The steepness of any incline can be measured as the ratio of the vertical change to the horizontal change. For example, a 5 % incline can be written as 5100 , which means that for every 100 feet forward, the height increases 5 feet.Figure 4.4.1 In mathematics incline of a line the slope and use the letter m to denote it. The vertical change is called the rise and the horizontal change is called the run.Slopem=vertical changehorizontal change=riserun(4.4.1)The rise and the run can be positive or negative. A positive rise corresponds to a vertical change up and a negative rise corresponds to a vertical change down. A positive run denotes a horizontal change to the right and a negative run corresponds to a horizontal change to the left. Given the graph, we can calculate the slope by determining the vertical and horizontal changes between any two points.Example 4.4.1 Figure 4.4.2 From the given points on the graph, count 3 units down and 4 units right.m=riserun=−3units4units=−34 the Answer is.m=−34 .

Semicircles are half circles that are divided at the diameter.
We want to find the semicircle arc.
To do this, just find the circumference of the circle and then divide by 2.
Circumference formula:
2rπ or Dπ
10π = 31.4
31.4 / 2 = 15.7
Now, we have to find the straight line part of the semicircle. The length of that straight line is the diameter. We already know that the diameter is 10.

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?
Answer:
0.571428571429 grams per cm³
Step-by-step explanation:
density = mass/volume
Let’s calculate the volume V of the pyramid :
V = (1/3)×base×height
= (1÷3)×(5×7)×9
= 105 cm³
Then
The density = mass/volume
= 60÷105
= 0.571428571429

Convert mixed fraction to improper fraction.
[tex]\sf w - 9\dfrac{1}{2}=15\\\\ w - \dfrac{19}{2}=15[/tex]
Now isolate 'w'
[tex]\sf w = 15 +\dfrac{19}{2}\\\\= \dfrac{15*2}{1*2}+\dfrac{19}{2}\\\\=\dfrac{30}{2}+\dfrac{19}{2}\\\\=\dfrac{30+19}{2}\\\\=\dfrac{49}{2}\\\\= 24\dfrac{1}{2}[/tex]
Answer:
[tex]\huge\boxed{\bf\:w = \frac{49}{2} = 24\frac{1}{2} = 24.5}[/tex]
Step-by-step explanation:
[tex]w - 9 \frac { 1 } { 2 } = 15[/tex]
Multiply both the sides of the equation by 2.
[tex]2w-\left(9\times 2+1\right)=30 \\2w-\left(18+1\right)=30 \\2w-19=30[/tex]
Bring [tex]19[/tex] to the left hand side of the equation.
[tex]2w=30+19 \\2w=49 \\\boxed{\bf\:w = \frac{49}{2} = 24\frac{1}{2} = 24.5}[/tex]

PAOLA GAVE AWAY 42 OF HER BOOKS SHE NOW HAS 150 BOOKS CALCULATE THE PERCENT CHANGE
HINT: how many books did she HAVE
please help me
Answer:
21.875%
Step-by-step explanation:
We need an equation to represent this problem,
Let x be the number of books she had before giving away 42 of them,
x - 42 = 150
To find out how many books she had before turn the problem around and add 42 with 150,
150 + 42 = x
⇒ x = 192
Now that you know that divide 42 by 192,
Let n be the quotient of 42/192
42/192 = n
⇒ n = 0.21875
Now to turn that into a percent move the decimal 2 spaces to the left,
0.21875
⇒ 2.1875
⇒ 21.875%
Therefore there was a 21.875% change.
