Answer:
There are 66 gold coins in the jar
Step-by-step explanation:
Let the number of silver coins = X
Then the number of gold coins = 3X (as there are 1/3 number of silver coins as gold)
Total coins =88
Total coins = silver coins + gold coins
Total coins = X + 3X = 88
Total coins = 4X = 88
X = 88/4
X = 22
No. Of silver coins = 22
No. Of gold coins = 3X = 3×22
No. Of gold coins = 3X= 66
Check
Total coins = 3X + X = 88
66+22 = 88
88 = 88
Hope it helps...
Have a great day :P
Answer:
Hello There!!
Step-by-step explanation:
Let the number of silver coins be x and gold coins be 3x which add up to 4x. Make an expression and add 88 with 4x so 4x=88
x=22(88÷4).
So x=22[silver coins]
3x=66(22×3) [gold coins]
hope this helps,have a great day!!

When Jaya goes bowling, her scores are normally distributed with a mean of 105 and a standard deviation of 10. Using the empirical rule, determine the interval that would represent the middle 95% of the scores of all the games that Jaya bowls.
Answer: (75, 135)
Step-by-step explanation:
Because the empirical rule is 3 standard deviations of the mean you would add and subtract to get your desired interval.
In this case our mean is 105 and our deviation is 10.
What you would do is add 10 to 105, 3 times to find your greatest number and the you would subtract 10 from 105, 3 times to get your lowest number.
105 + 10 + 10 + 10 = 135
105 - 10 - 10 - 10 = 75
Answer: (75, 135)
Answer:
Step-by-step explanation:
The answer is 85,125
How can you determine if the given lines are perpendicular?
Answer:
Step-by-step explanation:
Two lines are perpendicular if and only if the product of their slopes is . In other words, the slope of a line that is perpendicular to a given line is the negative reciprocal of that slope. Thus, for a line with a given slope of 3, the line perpendicular to that slope must be the negative reciprocal of 3, or .
Express as a trinomial.

[Exponential] |x|-2|-1|0|1|2| |y|2/9|2/3|2|6|18| When the x-value increases by 1, the y-value ________ (b-value)
Answer:
[tex]b = 3[/tex]
The value of y triples
Step-by-step explanation:
Given:
[tex]\begin{array}{cccccc}x & {-2} & {-1} & {0} & {1} & {2} \ \\ y & {\frac{2}{9}} & {\frac{2}{3}} & {2} & {6} & {18} \ \end{array}[/tex]
Required
Determine b value
An exponential equation is:
[tex]y = ab^x[/tex]
When [tex]x = 0; y =2[/tex]
So:
[tex]y = ab^x[/tex]
[tex]2 = a * b^0[/tex]
[tex]2 = a[/tex]
[tex]a = 2[/tex]
When [tex]x = 2; y = 18[/tex]
So:
[tex]18 = a * b^2[/tex]
Substitute 2 for a
[tex]18 = 2 * b^2[/tex]
Divide by 2
[tex]9 = b^2[/tex]
Take positive square roots of both sides
[tex]3 = b[/tex]
[tex]b = 3[/tex]

Given sinx=1/3, cosy=3/4, and both x and y are in quadrant iv, find cos(x-y) and sin(x+y)
Answer: [tex]\dfrac{6\sqrt{2}+\sqrt{7}}{12},\ \dfrac{-3-2\sqrt{14}}{12}[/tex]
Step-by-step explanation:
Given
x and y is in the fourth quadrant
[tex]\sin x=-\dfrac{1}{3}\\\\\cos y=\dfrac{3}{4}[/tex]
we know,
[tex]\cos (x-y)=\cos x\cos y+\sin x\sin y\\\sin (x+y)=\sin x\cos y+\cos x\sin y[/tex]
using [tex]\sin ^2\theta +\cos^2 \theta =1[/tex]
[tex]\Rightarrow \cos x=\dfrac{2\sqrt{2}}{3}\\\\\Rightarrow \sin y=-\dfrac{\sqrt{7}}{4}[/tex]
[tex]\Rightarrow \cos(x-y)=(\dfrac{2\sqrt{2}}{3})\times (\dfrac{3}{4})+(-\dfrac{1}{3})\times (-\dfrac{\sqrt{7}}{4})=\dfrac{6\sqrt{2}+\sqrt{7}}{12}\\\\\\\Rightarrow \sin (x+y)=(-\dfrac{1}{3})\times \dfrac{3}{4}+\dfrac{2\sqrt{2}}{3}\times (\dfrac{-\sqrt{7}}{4})=\dfrac{-3-2\sqrt{14}}{12}[/tex]

What is the distance between two points of a line?The distance between two points of a line is given as:
Distance = [tex]\sqrt{(c - a)^2 + (d - b)^2}[/tex]
Where (a, b) an (c, d) are the two points.
We have,
Hexagon PQRSTU.
Vertices.
P = (–1, 0)
Q = (–1, 3)
R = (1, 4)
S = (2, 5)
T = (4, 4)
U = (4, 0)
Now,
We can make 6 lines.
PQ, QR, RS, ST, TU, and PU
We find the distance between each line.
PQ = [tex]\sqrt{(-1 + 1)^2 + (3 - 0)^2}[/tex] = 3
QR = [tex]\sqrt{(1 + 1)^2 + (4 - 3)^2}[/tex] = √5
RS = [tex]\sqrt{(2 - 1)^2 + (5 - 4)^2}[/tex] = √2
ST = [tex]\sqrt{(4 - 2)^2 + (4 - 5)^2}[/tex] = √5
TU = [tex]\sqrt{(4 - 4)^2 + (0 - 4)^2}[/tex] = 4
PU = [tex]\sqrt{(4 + 1)^2 + (0 - 0)^2}[/tex] = 5
Now,
The perimeter of the hexagon.
= 3 + √5 + √2 + √5 + 4 + 5
= 12 + 2√5 + √2
Thus,
The perimeter of the hexagon is 12 + 2√5 + √2

The cost of the hiking trip this year is 2/3of the cost of last year's trip. This year's trip cost $32
1. Write an equation that represents the cost of last years trip.
2.What was the cost of last year's trip
Answer:
The equation is ( 32/2 ) × 3 = 48.
Step-by-step explanation:
In order to find the answer, we must find one third of last years trip. To do this, we can simply divide the cost of this year's trip by two, 32/2=16.
Now if we multiply this years trip by 3, 16×3=48, we can see that the total cost of last years trip was $48.
If we'd like to turn this into a equation, it looks like this:
( 32/2 ) × 3 = 48.

Answer:
i)
DA is diameter and AX is tangent to circleYour answer is correct
m∠ABD = 90°, m∠DAX = 90°ii)
Given m∠BAX = 42° and ∠DAB is complementary with BAX ⇒
m∠DAB = 90° - 42° = 48°DC = BC ⇒ intercepted arcs are same ⇒
∠CDB = ∠BDCmDC = mCB ⇒ mDCB = ∠DAB = 48° ⇒
m∠CDB = m∠BDC = 1/2*48 = 24°iii)
∠CBA
∠CBA is supplementary with ∠ADC as opposite angles of cyclic quadrilateral (∠ADB = ∠BAX = 42°)
m∠ADC = m∠ADB + m∠CDB = 42° + 24° = 68°m∠CBA = 180° - m∠ADC = 180° - 68° = 112°∠BAE
EA║CB and AB is transversal ⇒ CBA and BAE are supplementary angles:
