Answer:
3/10 + 1/2 = 8/10
Step-by-step explanation:
? + 1/2 = 8/10
To figure this out, you would subtract 8/10 from 1/2. But first, you want to find a common denominator.
1/2 = 5/10
8/10 - 5/10 = 3/10
3/10 can not be reduced anymore so that would be your answer.

B. Assume 1/16 in. waste in each cut. How many pins will you get?
Please explain how you got your answer for both A and B.
Answer:
A) 12 pins
B) 11 pins
Find the diameter of each circle. Round your answer to the nearest tenth
Please help and explanation will give BRAINLIST
Answer:
7.2
Step-by-step explanation:
to find the diameter you always times it by 2
whilst to find the radius you do diameter ÷ 2
so if you times 3.6 x 2 = 7.2
also, you can't round 7.2 to the nearest tenth because it's already in that form
Answer:
Step-by-step explanation:
a radius is the length of a line segment from the center of a circle to the edge of the circle
a diameter is the length of a line segment from both edges of a circle and passing through the center of a circle
the line segment in the diagram looks like a radius (assuming the black dot represents the center of the circle)
if you left the line segment where it is and then rotate another the line segment in the diagram around so that is straight in line with the original line segment you would see that you just created a diameter
the diameter is twice as long as one radius
a diameter = 2 times a radius d = 2r d = diameter r = radius
so d = 2 x 3.6 use your own calculator to solve

This is a sketch of the curve with equation y = f(x).
The vertex of the curve is at (2, -3)
V
X
(2, -3)
Write down the coordinates of the vertex of the curve with equation
a) f(x + 7)
b) f(-x)
I’m
Answer:
We have to use the formule to calculate the vertex which is: V(-b/2a;4ac-b^2/4a)
A) y=x+7 where a=1 b=0 and c=7
By replacing we have: V(0;28/4) V(0;7)
B) y=-x where a=-1 b and c=0 so V(0,0)

Drag numbers to show which one is closer to -1 and -1/4 on the number line
Answer:
-0.82 is closest to -1, and -0.28 is closest to -1/4
Step-by-step explanation:
you can start by converting all of them to a fraction or decimal:
-0.28 = -28/100 = -7/25 = -14/50
-0.82 = -82/100 = -41/50
-1/5 = -10/50
-4/5 = -40/50
-1 = -50/50
-1/4 = -12.5/50
a. What is the circumference of the
largest circle that can be cut from a
square measuring 30 cm on a side?
Use 3.14 for Pie
b. What percent of the perimeter of the
square is the circumference of the
circle?
Answer:
a) 94.2 cm
b) 78.5%
Step-by-step explanation:
a) since the square side = 30 cm
it means the diameter = 30 cm
then circumference of the largest circle that can be cut = 3.14×30 = 94.2 cm
b) the perimeter of the square = 30×4 = 120
94.2 for 120
x% for 100%
x = (100×94.2)/120 = 9420/120 = 942/12 = 78.5%

find x given the function f(x)=4x-7 where f(x)=9
Answer:
4
Step-by-step explanation:
You set f(x) = 9 and solve from there.
9 = 4x - 7
+7 +7
16 = 4x
/4 /4
x = 4
Answer:
The answer is 4
Step-by-step explanation:
f(x)=4x-7
f(x)=9
9=4x-7
9+7=4x-7+7
(the -7 and the +7 cancel out, and remember: whatever you do the one side you have to do to the other)
16=4x
(divide by 4 to isolate x and do the same to the other side of the equation so you get the answer)
so, x=4
Write an equation that could be used to find the value of x using the interior angles of ∆ABD, then solve the equation.
Answer:
equation: 55 + (2x + 3) + 90 = 180
55 + 2x + 3 + 90 = 180
2x + 148 = 180
2x = 32
x = 16
Answer:
55 + 50 + 2x+3 + 2x+8 = 180
x = 16
Step-by-step explanation:
55 + 50 + 2x+3 + 2x+8 = 180
113 + 4x = 180
4x = 64
x = 16
SOMEONE HELP PLEASE!IM SO CONFUSED
9514 1404 393
Answer:
arc MKL ≈ 19.02 m
Step-by-step explanation:
The figure shows angle KNL is the complement of angle KNJ, so is ...
∠KNL = 90° =∠KNJ
∠KNL = 90° -52° = 38°
We know that KM is a diameter, so arc MJK = 180°, and ...
arc MKL = 180° +38° = 218°
In radians, that angle measure is ...
218° × π/180° rad = 109π/90 rad
An arc length is given by the formula ...
s = rθ . . . . . where r is the radius and θ is the radian measure of the arc
For this problem, the radius is MN = 1/2MK = 5 m, and the length of arc MKL is ...
s = rθ
arc MKL = (5 m)(109π/90) = 109π/18 m
arc MKL ≈ 19.02 m
SE TIENE 45 NIÑOS Y 35 NIÑAS. DE LOS CUALES 60 VIVEN EN EL DISTRITO DE BREÑA. SI EL 30% QUE NO VIVEN EN BREÑA SON MUJERES. ¿QUÉ CANTIDAD SON VARONES?
Answer:
14 son varones
Step-by-step explanation:
Primero tenemos que sumar la cantidad de niños y niñas para saber cuantos hay en total
45 + 35 = 80
60 de ellos viven en el Distrito de Breña entonces los descontamos del total
80 - 60 = 20
Esto nos dice que 20 NO viven en Breña. Si 30% son mujeres quiere decir que el resto 70% son varones. Asi que multiplicamos los 20 por 70% en formato decimal que seria 0.70
20 * 0.70 = 14
Finalmente, podemos ver que 14 son varones viviendo fuera de Breña

A line intersects the points (13,-4) and (1, 12). Find the slope and simplify completely. Enter the correct symbol, + or - Slope = tn 28 Enter
Answer:
The slope of the line that intersects the points (13, -4) and (1, 12) is 4/-3.
Step-by-step explanation:
The equation [tex]m=\frac{y2-x2}{y1-x1}[/tex] is used to solve for slope [tex]m[/tex].
[tex]m=\frac{12-(-4)}{1-13}=\frac{12+4}{-12} =\frac{16}{-12} =\frac{4}{-3}[/tex]
If you need it in decimal form, then 4/-3=-1.33333333333

Can someone pls explain Pythagorean Theorem to me
Thank you
Answer:
Pythagoras theorem states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“. The sides of this triangle have been named as Perpendicular, Base and Hypotenuse. Here, the hypotenuse is the longest side, as it is opposite to the angle 90°.
Answer: In mathematics, the Pythagorean theorem, or Pythagoras's theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.

The height in ft of a rocket after x seconds is given by y=128-16x^2y. What is the maximum height reached by the rocket, and how long does it take the rocket to reach max height.
Answer:
Max height = 128feet
Time = 0secs
Step-by-step explanation:
Given the height in ft of a rocket after x seconds is given by y=128-16x^2, at maximum height, the velocity of the object is zero that is;
dy/dx = 0
0 - 32x = 0
x = 0/-32
x = 0
Hence the time taken for the object to reach its maximum height is 0 secs
To get the maximum height reached, you will substitute x = 0 into th expression given as shown;
y = 128 - 16x^2
y = 128 - 16(0)^2
y = 128 - 0
y = 128feet
Hence the maximum height reached by the rocket is 128feet
0.5+2x < 14.5 whats the answer
Answer:
x < 7
Step-by-step explanation:
0.5 + 2x < 14.5
2x < 14.5 - 0.5
2x < 14
x < 14 ÷ 2
x < 7
( To solve this is basically solving an equation. It's just that that instead of an equal sign, a greater than, less than, greater than or equal to or a less than or equal to sign is present. )

How many solutions does the system have?
y=3x+3
y=−2x+3
choose 1 answer
A) Exactly one solution
B) No solutions
C) Infinitely many solutions
Answer:
A
Step-by-step explanation:
Given the 2 equations
y = 3x + 3 → (1)
y = - 2x + 3 → (2)
Substitute y = 3x + 3 into (2)
3x + 3 = - 2x + 3 ( add 2x to both sides )
5x + 3 = 3 ( subtract 3 from both sides )
5x = 0 , then
x = 0
Substitute x = 0 into (1)
y = 3(0) + 3 = 0 + 3 = 3
solution is (0, 3 ) → A
