Answer:
2/3
Step-by-step explanation:
A six sided number cube :
Sample space = (1, 2, 3, 4, 5, 6)
Non composite numbers on a six sided number cube = (1, 2, 3, 5)
Probability of an event = required outcome / Total possible outcomes
Required outcome = number of non composite numbers = 4
Total possible outcomes = sample space = 6
P(not composite) = 4 / 6 = 2/3
x + 2y = 1 and 2x + 5y = 3.
Can someone help me , with process to please ?
I will appreciate thank you so much!
Answer:
x = -1
y = 1
Step-by-step explanation:
x + 2y = 1 (Multiply this by -2)
2x + 5y = 3
-2x - 4y = -2
2x + 5y = 3
y = 1
x + 2y = 1
x + 2(1) = 1
x + 2 = 1
x = 1 - 2
x = -1
Answer:
x = -1
y = 1
Step By Step Explanation:
x + 2y = 1
2x + 5y = 3
let x become the subject. use one of the equation.
x = 1 - 2y
substitute into another equation
2(1 - 2y) + 5y = 3
expend the bracket
2 - 4y + 5y = 3
collect like terms
- 4y + 5y = 3 - 2
y = 1
substitute into one of the equation to find x
x + 2y = 1
x + 2 (1) = 1
x + 2 = 1
collect like terms
x = 1 - 2
x = - 1

Kwame and Karen both deposited $2 000 in separate savings accounts.

What will be the combined balance of their accounts after 4 years?
Answer:
2248+2224.91= 4472.91
Step-by-step explanation:
A = $2,248.00
I = A - P = $248.00
Equation:
A = P(1 + rt)
Calculation:
First, converting R percent to r a decimal
r = R/100 = 3.1%/100 = 0.031 per year.
Solving our equation:
A = 2000(1 + (0.031 × 4)) = 2248
A = $2,248.00
The total amount accrued, principal plus interest, from simple interest on a principal of $2,000.00 at a rate of 3.1% per year for 4 years is $2,248.00.
A = $2,224.91
A = P + I where
P (principal) = $2,000.00
I (interest) = $224.91
Calculation Steps:
First, convert R as a percent to r as a decimal
r = R/100
r = 2.7/100
r = 0.027 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 2,000.00(1 + 0.027/1)(1)(4)
A = 2,000.00(1 + 0.027)(4)
A = $2,224.91
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $2,000.00 at a rate of 2.7% per year compounded 1 times per year over 4 years is $2,224.91.
Addison has some puzzle books. She will buy 7 new puzzle of books each year.
She will have 43 puzzle books in 5 years.
Rate of change per year____
Initial value____
Help me please :))) <3 ~
Answer:
7
8
Step-by-step explanation:
The rate of change per year is the number of books she gets each year.
The problem states "She will buy 7 new puzzle of books each year."
The rate of change per year is 7.
The initial value is the beginning value.
She gets 7 book each year. In 5 years, she gets 5 * 7 = 35 books.
She will have 35 additional books in 5 years. She will have a total of 43 books in 5 years.
43 - 35 = 8
She started with 8 books.
The initial value is 8.

5+2x = -27/8
How explain
Answer:
x = -4 3/16.
Step-by-step explanation:
First, convert -27/8 to a mixed number. -3 3/8.
So we can take 5 + 2x = -3 3/8 and subtract 5 from both sides (to get rid of the 5 on the left)
The equation turns into this: 2x = -8 3/8.
Now we can divide by 2 on both sides.
The equation becomes x = -4 3/16.

Michelle and Natasha each had to repair their new iPhones. The initial cost of each repair is $ 100. Michelle and Natasha each have two discount coupons. Each of them uses both coupons toward the cost of the repair. One coupon is for $25 off the repair cost and the other coupon is for 20% off the repair cost. Michelle and Natasha use their coupons in a different order, as shown below. Michelle uses the 20% off the repair cost coupon first. She then uses the $25 off the repair cost coupon on the remaining balance. Natasha uses the $25 off the repair cost coupon first. She then uses the %20% off the repair cost coupon on the remaining balance.

A teacher wants to choose a student at random. The teacher decides to choose the first person to walk through the classroom door at the start of the lesson.
a. Explain why this is not a good method.
2. Suggest a better method.
Answer:
The first person to arrive is not random. The person that mostly arrives first every time is the person who lives closest to the school, or is a teacher's pet.
The odds of the person who lives 20km away from the school being first are way lower than anyone else.
A better method, would be everyone writes their name on a paper, and the teacher picks one at random from a hat.
∠A and ∠B form linear pair. If m∠A =(6x-19)° and m∠B=(11x-22)°, find m∠B.
Answer: 121°
Step-by-step explanation:
The measure of angle B will be [tex]121^0[/tex] .
What is angle?Angle is formed by two rays lie in the plane that contains the rays.
We have,
[tex]m \angle A =(6x-19)^0[/tex]
Now,
Linear pair angles are those angles whose sum is [tex]180^0[/tex] .
i.e.
[tex]m \angle A + m \angle B=180^0[/tex]
So,
[tex](6x-19)^0 +(11x-22)^0 =180^0[/tex]
Now,
[tex]17x-41=180[/tex]
[tex]17x=221[/tex]
[tex]x=13[/tex]
So,
[tex]m\angle B=(11x-22)^0[/tex]
Putting value of x;
[tex]m\angle B=(11*13-22)^0[/tex]
[tex]m\angle B=(121)^0[/tex]
So, measure of angle B is [tex]121^0[/tex].
Hence, we can say that the measure of angle B will be [tex]121^0[/tex] .

write an equation of the line passing through the point A(8,2) that is perpendicular to the line y=4x-7
Answer:
y - 2 = (-1/4)(x - 8)
Step-by-step explanation:
The slope of the given line is 4. The slope of any line perpendicular to the given line is the negative reciprocal of 4, which is -1/4.
Use the point-slope formula:
y - k = m(x - h), where (h, k) is the given point.
Then: y - 2 = (-1/4)(x - 8)

Find measure FGH circles unit
Answer:
[tex] \huge \orange{m\widehat {FGH} =238\degree} [/tex]
Step-by-step explanation:
Quadrilateral AFGH is inscribed in a circle. So, it is a cyclic quadrilateral. Opposite angles of a cyclic quadrilateral are supplementary.[tex] \therefore m\angle FGH + m\angle FAH = 180\degree [/tex]
[tex] \therefore (21x-2)\degree + (38x +5)\degree = 180\degree [/tex]
[tex] \therefore (21x-2+38x +5)\degree = 180\degree [/tex]
[tex] \therefore 59x+3= 180[/tex]
[tex] \therefore 59x= 180-3 [/tex]
[tex] \therefore 59x= 177 [/tex]
[tex] \therefore x= \frac{177}{59}[/tex]
[tex] \therefore x=3[/tex]
Now, by inscribed angle theorem:
[tex] m\angle FAH = \frac{1}{2} m\widehat {FGH} [/tex]
[tex] (38x +5)\degree = \frac{1}{2} m\widehat {FGH} [/tex]
[tex] 2(38\times 3+5)\degree = m\widehat {FGH} [/tex]
[tex] 2(119)\degree = m\widehat {FGH} [/tex]
[tex] 238\degree = m\widehat {FGH} [/tex]
[tex] \huge \purple {\boxed {m\widehat {FGH} =238\degree}} [/tex]

from a point P the length of the tangent to a circle is 24 cm and the radius is 7 cm find the distance of P from the centre
Answer:
22.96 cm
Step-by-step explanation:
Let the point of contact of the tangent with the circle be R.
Let the centre of the circle be O.
We are told that from Point P, the length of the tangent is 24 cm.
Thus, PR = 24 cm
Now, the radius will be perpendicular to the tangent at the point of contact with the circle.
Thus, ORP will form a right angle triangle where ∠R = 90°
Since radius = 7 cm, we can use pythagoras theorem to find OP which is the distance of P from the centre.
Thus;
OP = √(24² - 7²)
OP = √527
OP = 22.96 cm
