Answer:
60%
Step-by-step explanation:
percent of green marbles = (total number of green marbles / total number of marbles in the bag) x 100
total number of marbles in the bag = 30 + 20 = 50
30 / 50 x 100 = 60%
Answer:
60%

Enter your answer in the box.
Answer:
5 - 3 = 2
2x =2
x = 2x ÷ 2 = 1
Answer is 1
Answer:
5=2x-3
collect like terms
if -3 crosses the equal to sign it will change to +3
5+3=2x
8=2x
divide both sides by 2

The electric current is I, is amperes, in a circuit varies directly as the voltage V. When 12 volts are applied the current is 4 amperes. What is the current when 18 volts are applied
Answer: 6 A
Step-by-step explanation:
Given
Current varies directly with Voltage
i.e.
[tex]I\ \propto V\ or\\V\ \propto\ I\\V=IR[/tex]
when V=12 V, I=4 A i.e.
[tex]\Rightarrow 12=4R\\\Rightarrow R=3\ \Omega[/tex]
When V=18 V
[tex]\Rightarrow 18=I\times 3\\\Rightarrow I=6\ A[/tex]
Current is 6 Ampere

Find the value of in the triangle shown below.
2.5
2
6.5
I have attached the complete question with the triangle.
Answer:
x = 6
Step-by-step explanation:
From the image attached we are told to find x in the triangle.
The triangle is a right angle triangle and so we can use pythagoras theorem to find x.
x² = 6.5² - 2.5²
x² = 42.25 - 6.25
x = √36
x = 6

The radius of a regular hexagon is 8 cm.
Find the apothem, perimeter and area
of the regular hexagon.
the measure of the side = of the measure of radius because the regular hexagon have 6 sides = at each others
meaning the measure the perimeter is = 6 times the radius
and the radius = 8cm
so perimeter = 6× 8 cm
perimeter = 48cm
since the apothem is the segment perpendicular to a side thought the center and those segment are not promotional we have the notation as
r square root of 3 divided by 2
r = radius = 8 cm
by apply the formula
8square root 3 divided by 2
so the area will be
since the perimeter is 48cm
and the apothem is 8 square root of 3 divided 2
so the area will be 48 times 8 square root of 3 divided by 2 = 384 square of 3 divided by 2 .
hope that helps.
Find the limit of the function by using direct substitution. limit as x approaches three of quantity x squared plus three x minus one.
17
0
-17
does not exist
Answer:
17
Step-by-step explanation:
Given the limit of a function expressed as;
[tex]\lim_{x \to 3} x^2 + 3x - 1[/tex]
Substitute x = 3 into the function to have;
[tex]= 3^2 + 3(3) - 1\\= 9 + 9 -1 \\= 18 - 1\\= 17[/tex]
Hence the limit of the function as x tends to 3 is 17
Two sides of a triangle have lengths 7 and 15. Which inequality represents the possible lengths for the third side , x?
Answer:
8 < x <22
Step-by-step explanation:
In this question we know the two sides of the triangle to be 7 and 15, let's all the other side x
One one side of the inequality we have:
7+15>x
22 > x
On the other side we have
7 + x > 15
X > 15-7
X>8
When we rearrange these inequalities above we have
8<X<22
We saw from the calculations that 8 is less than X and X is less than 22.
Sally's age is 2 plus 3 times John's age. Together, Sally and John's age equals 30. How old is Sally?
Answer:
Sally is 23 years old.
Step-by-step explanation:
John's age is completely unknown, so it is known as x
Meanwhile, Sally's age can be represented as 3x+2
The sum of both ages is 30.
So, x+3x+2=30
Combine like terms.
4x+2=30
Subtract 2 from both sides.
4x=28
Divide both sides by 4.
x=7
John is 7 years old.
Sally's age: 3(7)+2=23
Sally is 23 years old.
Rico spins the spinner twice and determines the sums of the spins. Fill in the sample space to determine the possible outcomes. What is the probability that Rico will get a sum less than or equal to 8? A 13\frac{1}{3} 3 1 B 23\frac{2}{3} 3 2 C 89\frac{8}{9} 9 8 D 59\frac{5}{9} 9 5
Answer:
2/3
Step-by-step explanation:
Sample space for the sum of 2 spins :
Number on spinner = 2, 5, 4
____ 2 ___ 5 _____4
2___ 4 ___ 7 _____ 6
|
5___ 7 ___ 10 ____ 9
|
4___ 6 ___ 9 ____ 8
Hence,
(4, 7, 6, 7, 10, 9, 6, 9, 8)
Probability of getting a sum less than or equal to 8;
Probability = required outcome / Total possible outcomes
Required outcome =, sum ≤ 8 = 6
Total possible outcomes = 9
P(sum ≤ 8) = 6/9 = 2/3

The slope-intercept form of the equation of a line that passes through point (–2, –13) is y = 5x – 3. What is the point-slope form of the equation for this line?
Answer:
y + 13 = 5(x + 2)
Step-by-step explanation:
the point is (-2 , -13)
Point slope form is: y - y1 = m(x - x1)
y1= -13
x1= -2
y - -13 = 5 (x - -2)
y +13 = 5(x+2)
what is the equation for this line
Answer:
y=-1.5x+0.5 or y+1.5x-0.5=0

Answer:
Step-by-step explanation:
aster sold 18 oranges if this are 12% of her total oranges how many oranges are not sold
Answer:
132.
Step-by-step explanation:
If 12% are sold then 100-12 = 88% are unsold.
12% = 18 oranges
1% = 18/12 = 1.5 oranges,
88% = 1.5 * 88 = 132.
