Answer:
4/6
Step-by-step explanation:
1/2 needs to be converted to sixths, so we would multiple the numerator and the denominator by 3, because 2 goes into 6, 3 times, then we would get 3/6 + 1/6, then just add, 1 + 3 = 4, and then you end up with 4/6. Have A Great Day!
Calculate the distances from the origin to points A(11, –2, –6) and B(–3, 7, –5). Round to the nearest tenth. The distance from the origin to point A is units. The distance from the origin to point B is units. Now determine how much farther from the origin point A is than point B. Round to the nearest tenth. Point A is units farther from the origin than point B.
Answer:
Step-by-step explanation:
A(11, –2, –6) and B(–3, 7, –5) are located away from the origin (0,0,0), the points from the origin to this points is expressed as OB - OA where;
OB is the distance from the origin to the point B
OA is the distance from the origin to the point A
Using the formula for calculating distance between two points
OA = √(z2-z1)²+(y2-y1)²+(x2-x1)²
OA = √(-6-0)²+(-2-0)²+(11-0)²
OA = √(-6)²+(-2)²+(11)²
OA = √36+4+121
OA = √161
OA = 12.688
Similarly;
OB = √(-5-0)²+(7-0)²+(-3-0)²
OA = √(-5)²+(7)²+(-3)²
OA = √25+49+9
OA = √83
OA = 9.110
Distance from the origin to the points = 12.688 - 9.110 = 3.577
Distance from the origin to the points ≈ 3.6 (to the nearest tenth)
Answer:
The distance from the origin to point A is 12.7 units.
The distance from the origin to point B is 9.1 units.
Point A is 3.6 units farther from the origin than point B.

Albert's mom has 2,523 reward points from shopping at an online store. She uses the points to buy gift cards for free cups of coffee. Each gift card costs 75 points. What is the greatest number of gift cards Albert's mom can buy? How many reward points will she have left? Use the drop-down menus to choose the numbers that make the statement true.
Answer:
Maximum number of gift cards she can purchase = 33
Reward points left with her = 48
Step-by-step explanation:
Let Albert's mom buys the number of gift cards = x
Points for each gift card = 75
Total points consumed to buy x gift cards = 75x
If total points with Albert's mom = 2523
So the remaining points with her = (2523 - 75x)
Inequality representing the remaining points will be,
(2523 - 75x) ≥ 0
75x ≤ 2523
x ≤ [tex]\frac{2523}{75}[/tex]
x ≤ 33.64
Maximum number of cards she can buy = 33
Therefore, reward points with her = 2523 - (75 × 33)
= 2523 - 2475

So, 3x+5x=120
8x=120
x=15
David got 3x = 3*15 = $45
Answer:
45$
Step-by-step explanation:
120/8=15
15*3=45
because it is 3:5 ratio
f(x)=x^2+6x+7
g(x)=x+2
find g(f(x))
Answer:
g(x2+6x+7)=x2+6x+9
Step-by-step explanation:
Evaluate g(f(x)) by substituting in the value of f into g
g(2x)=6(2x)−7
Multiply 2 by 6
g(2x)=12x−7

to the nearest mm = 19.0cm
what is the mathematical sentence of "the length of wooden frame is 1foot longer than it's width and it's area is equal to 12ft²" can you translate it into quadratic equation in terms of "x"?
Answer:
x²+x+12 = 0
Step-by-step explanation:
Area if the wooden frame = ,Length ×Width
A = LW
If the length of wooden frame is 1foot longer than it's width, then;
L = W+1
Given
A = 12ft²
Substitute the derived and given parameters into the formula to have;
P = (W+1)W
12 = (W+1)W
Open the parentheses
12 = W²+W
Subtract 12 from both sides
12-12 = W²+W -12
0 = W²+W-12
Rearrange
W²+W-12 = 0
If W = x
The quadratic equation becomes:
x²+x+12 = 0

In the diagram below
Answer:
m∠A = 39°
Step-by-step explanation:
From the figure attached,
BE ≅ BC
m∠C = 32°
m∠BFD = 103°
In ΔBCE,
m∠E = m∠C = 32° [Since, BE ≅ BC]
m∠E + ∠C + m∠EBC = 180°
32° + 32° + m∠EBC = 180°
m∠EBC = 116°
m∠EBC + m∠EBA = 180° [Linear pair of angles]
116° + m∠EBA = 180°
m∠EBA = 64°
Similarly, m∠AFB + m∠DFB = 180° [Linear pair of angles]
m∠AFB + 103° = 180°
m∠AFB = 77°
Now in ΔAFB,
m∠A + m∠AFB + m∠FBA = 180° [Sum of internal angles of a triangle = 180°]
m∠A + 77° + 64° = 180°
m∠A = 39°

7:x=2:3
What is the answer can not find out
Answer:
10.5 = x
Step-by-step explanation:
7:x = 2:3
can be rewritten as
7/x = 2/3
because, a proportion is the same as a fraction, which is the same as division
so now use cross products to solve the equations
7/x = 2/3
7 * 3 = 2 * x
simplify
21 = 2x
inverse operations
21 = 2x
/2 /2
10.5 = x

Answer:
y = 136
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
y is an exterior angle of the triangle, thus
y = 82 + 54 = 136
Find the equation perpendicular to y =1/2x - 3 and goes through the point (6, -3).
Perpendicular equations have opposite reciprocal slopes, so any equation perpendicular to the equation y = 1/2 x - 2 would have the slope -2.
Now plug in the point (6, -3) into the equation y = -2x + b to find out what b is.
-3 = -2(6) + b
Multiply -2 by 6.
-3 = -12 + b
Add 12.
9 = b
So the equation is y = -2x + 9

A coin weighs 5/6 ounces. Ann picked up 3 of these coins.
What is the total weight of the coins she picked up?
Write your answer in simplest form.
Answer:
2 1/2 ounces
Step-by-step explanation:
If each coin is 5/6 ounces and she picks up 3, we must multiply the two numbers
5/6 × 3
3 can also be written as 3/1
5/6 × 3/1
multiply the numerators and denominators separately
5 × 3/6 × 1
15/6
Both 15 and 6 have a common factor of 3 so divide both numbers by 3
15 ÷ 3/6 ÷ 3
5/2
This is simplest form in terms of improper fractions
If you want it as a whole number it would be:
2 1/2
This is because 2 goes into 5 twice evenly (whole number) with one remaining (numerator; denominator stays the same)
Hello
Answer:
2.5 ounce
Step-by-step explanation:
Weight of each coin=5/6 ounce
Weight of 3 such coins= 3*5/6
= 2.5 ounces
Hope its in the simplest form....
