Answer:
It would be positive
Step-by-step explanation:
To do anything with fractions you need to find a common denominator, in this case lets say its 128. the 9 in the negative side would need to be multiplied by 8 like it's denominator making it 72. You would do the same to the other fraction giving you the fractions -72/128 and 144/128 from here you add to get 72/128 which is positive
Answer:
positive
Step-by-step explanation:
-9/16= -0.5625
9/8= 1.125
-9/16+9/8= -0.5625 + 1.125(in the addition of opposite signs u should figure out the largest num and should substract the other numa nd assign the sign of the biggest nym)
=0.5625
the reason
+ * + = +
- * - = +
+ * - = -
+/+ =+
- / - = -
-/ + = -
+ / - = -

Find the inverse of the function. *
Answer:
C.
Step-by-step explanation:
1.) switch x and y
x=(7y+18)/2
2.) multiply both sides by 2
2x=7y+18
3.) subtract 18 from both sides
2x-18=7y
4.) divide both sides by 7
(2x-18)/7=y

Write the slope-intercept form of the equation for the line that passes through the point (-1,3) and has a slope of 5/3
Answer:
[tex]y=\frac{5}{3}x+4\frac{2}{3}[/tex]
Step-by-step explanation:
slope-intercept form: y = mx + b
Given:
Slope(m) = [tex]\frac{5}{3}[/tex]
Point = (-1, 3)
To write the equation in slope-intercept form we need to know the slope(m) and the y-intercept(b). Since we already know the value of m, we can use it and the given point to find b:
[tex]3=\frac{5}{3}(-1)+b[/tex]
[tex]3=-\frac{5}{3}+b[/tex]
[tex]4\frac{2}{3}=b[/tex]
Now that we know the values of b and m, we can write the equation:
[tex]y = \frac{5}{3}x+4\frac{2}{3}[/tex]

A small ice cream cone costs $2.00, a medium costs $2.75, and a large costs $3.25. Special toppings cost
extra. Melanie's medium cone with 2 toppings cost $3.35. What is the unit rate of cost per number of toppings
for a medium cone?
Answer:
0.30 per topping
Explanation:
3.35 - 2.75= 0.60
0.60 / 2 = 0.30

Answer:
B. 75.8 ft²
Step-by-step explanation:
The height of each triangle can be found using the Pythagorean theorem. The given edge length (7 ft) is the hypotenuse of the triangle, and the base edge length is twice one leg of the triangle.
The height of the triangle on the 2 ft faces is ...
√(7² -1²) = √48 = 4√3
The height of the triangle on the 8 ft faces is ...
√(7² -4²) = √33
The areas of the triangular faces are the product of the height and half the base length:
A = 1/2bh
2 ft edge triangle area = (1/2)(2 ft)(4√3 ft) = 4√3 ft²
8 ft edge triangle area = (1/2)(8 ft)(√33 ft) = 4√33 ft²
__
The area of the rectangular base is ...
A = LW
A = (8 ft)(2 ft) = 16 ft²
__
The total surface area of the pyramid is the sum of the areas of the triangular faces and the area of the rectangular base.
2(4√3 +4√33) +16 = 8(2+√3+√33) ≈ 75.813
The total surface area is about 75.8 ft².

Answer:
21/10 mph
Step-by-step explanation:
When you divide a fraction with another fraction, the number after the division sign gets flipped (meaning that the numerator and denominator switch so 1/2 would be 2/1)
So using that we can solve this:
7/5 / 2/3
7/5 * 3/2
21/10 miles per hour

Step-by-step explanation:
1. By interior angle sum Postulate of a triangle.
[tex] m\angle a+ m\angle y +m\angle z= 180\degree.... (1)\\\\
m\angle a+ m\angle w +m\angle x= 180\degree.... (2)\\\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle a+ m\angle y +m\angle z= m\angle a+ m\angle w +m\angle x\\\\
m\angle y +m\angle z= m\angle w +m\angle x\\[/tex]
Hence proved
2. In [tex] \triangle PQS, \: \angle QSR [/tex] is exterior angle.
Therefore, by remote interior angle theorem, we have:
[tex] m\angle QPS + m\angle PQS= m\angle QSR\\\\
x + m\angle PQS= 2x\\\\
m\angle PQS= 2x-x\\\\
m\angle PQS = x.... (1)\\\\
m\angle QPS = x.... (given).... (2)\\[/tex]
From equations (1) & (2), we find:
[tex] m\angle PQS = m\angle QPS\\\\
\therefore \angle PQS \cong \angle QPS\\\\
\therefore PS \cong QS\\(sides\: opposite \: to\: congruent \:\angle s) \\\\[/tex]
[tex] \therefore \triangle PQS [/tex] is an isosceles triangle.
Thus proved.

A cylinder and a cone have the same diameter: 8 inches. The height of the cylinder is 5 inches. The height of the cone is 15 inches.
Use n = 3.14.
What is the relationship between the volume of this cylinder and this cone? Explain your answer by determining the volume of each and comparing them
Step-by-step explanation:
Volume of a cylinder is:
V = πr²h
V = (3.14) (4 in)² (5 in)
V = 251.2 in³
Volume of a cone is:
V = ⅓ πr²h
V = ⅓ (3.14) (4 in)² (15 in)
V = 251.2 in³
The volumes are equal.

Write the Linear equation in Standard form.. Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php, write an equation in standard form modeling this situation. Let x represent the number of pairs of socks you buy, and y represent the number of pairs of gloves you buy.
Answer:
An equation in standard form modeling this situation is:
75x + 50x = 425
Step-by-step explanation:
Let
x represent the number of pairs of socks you buy
y represent the number of pairs of gloves you buy
Each pair of Socks in store cost 75php, and each pair of gloves costs 50php. If you want to spend exactly 425php.
The equation is given as:
75php × x + 50php × y = 425php
= 75x + 50y = 425
Therefore,
the equation in standard form modeling this situation is:
75x + 50x = 425

Answer:
12[tex]x^{4}[/tex]y[tex]z^{7}[/tex]√3x
Step-by-step explanation:
2√108[tex]x^{9}[/tex]y²[tex]z^{14}[/tex]
so you will need two of something to take one out from under the squareroot
we can rewrite [tex]z^{14} = z^{7} *z^{7}[/tex] so we can take a [tex]z^{7}[/tex] out
we can rewrite y² as y*y so we can take a y out
we can rewrite [tex]x^{9}[/tex] as [tex]x^{4} *x^{4} *x[/tex] so we can take a [tex]x^{4}[/tex]out
for 108 think what is the smallest prime number that divides 108 and is 2
108= 2*54
same algorithm, smallest prime number that divides 54 is 2 so
108=2*2*27
same algorithm, smallest prime number that divides 27 is 3 so
108=2*2*3*9
we know 9 is 3*3 so
108=2*2*3*3*3 we can take out one 2 and one 3
put them all toghether now
2*2*3*[tex]x^{4}[/tex]*y*[tex]z^{7}[/tex]√3x = 12[tex]x^{4}[/tex]y[tex]z^{7}[/tex]√3x
