What pair of factors of -45 has a
sum of 4?
Answer:
9 and -5
Step-by-step explanation:
9*-5=-45
9+-5=4
The pair of factors is 9 and -5.
What is a factor?
The factor of a number is another number that can divide the first number without any remainder.
Let, one of the factors is x.
Then, the other factor is = -45/x.
Given,
x + (- 45/x) = 4
⇒ x - 45/x = 4
⇒ x - 45/x - 4 = 0
⇒ x² - 45 - 4x = 0
⇒ x² - 4x - 45 = 0
⇒ x² - 9x + 5x - 45 = 0
⇒ x(x-9) + 5(x-9) = 0
⇒ (x-9) (x+5) = 0
Hence, x = 9, -5.

There are only 4 mint biscuits and 1 toffee biscuit in a tin. There are only 5 mint sweets and 3 strawberry sweets in a packet. Michaels mum lets him take one biscuit from the tin and one sweet from the packet. Michael takes a biscuit at random from the tin. He also takes a sweet at random from the packet. Work out the probability that either the biscuit is mint, but not both.
Answer:
0.425
Step-by-step explanation:
Given that there are 4 mint biscuits and 1 toffee biscuit in a tin and 5 mint sweets and 3 strawberry sweets in a packet.
So, the total number of biscuit in tin = 4+1= 5 and
Number of mint biscuit in tin = 4
Number of toffee biscuit in tin = 1
So, the probability of picking 1 mint biscuit from tin,
[tex]p_1[/tex]=(Number of mint biscuit in tin)/(Total number of biscuit in the tin)
[tex]\Rightarrow p_1 =4/5 = 0.8[/tex]
The probability of picking 1 toffee biscuit from tin,
[tex]p_2[/tex] =(Number of toffee biscuit in tin)/(Total number of biscuit in the tin)
[tex]\Rightarrow p_2=1/5 = 0.2[/tex]
Similarly, the total number of sweets in the basket = 5+3=8 and
Number of mint sweets in the basket = 5
Number of strawberry sweets in the basket = 3
So, the probability of picking 1 mint sweets from the basket,
[tex]p_3[/tex] =(Number of mint sweets in the basket)/(Total number of sweets in the basket)
[tex]\Rightarrow p_3=5/8 = 0.625[/tex]
The probability of picking 1 strawberry sweets from the basket
[tex]p_4[/tex] =(Number of strawberry sweets in the basket)/(Total number of sweets in the basket)
[tex]\Rightarrow p_4=3/8 = 0.375[/tex]
As Michael takes a biscuit from the tin as well as a sweet from the packet randomly, so the possible combinations can be
A) 1 mint biscuit and 1 mint sweets,
B) 1 toffee biscuit and 1 strawberry sweets,
C) 1 mint biscuit and 1 strawberry sweets, and
D) 1 mint sweets and 1 toffee biscuit.
Here, (C) and (D) are the desired case of either the biscuit is mint, but not both.
So, the probability of either the biscuit is mint, but not both
= Probability of ( 1 mint biscuit and 1 strawberry sweets) or (1 mint sweets and 1 toffee biscuit)
[tex]=p_1 \times p_4 + p_2\times p_3 \\\\=0.8 \times 0.375 + 0.2\times 0.625 \\\\=0.425[/tex]
Hence, the probability of either the biscuit is mint, but not both is 0.425

Using compound interest, it is found that it would take 11 years for the value of the account to reach $70,900.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.Hence, the parameters are given as follows:
[tex]A(t) = 70900, P = 37000, n = 365, r = 0.057[/tex]
We have to solve for t, then:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]70900 = 37000\left(1 + \frac{0.057}{365}\right)^{365t}[/tex]
[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = \frac{70900}{37000}[/tex]
[tex]\left(1 + \frac{0.057}{365}\right)^{365t} = 1.91621622[/tex]
[tex](1.00015616)^{365t} = 1.91621622[/tex]
[tex]\log{(1.00015616)^{365t}} = \log{1.91621622}[/tex]
[tex]365t\log{1.00015616} = \log{1.91621622}[/tex]
[tex]t = \frac{\log{1.91621622}}{365\log{1.00015616}}[/tex]
t = 11.41
Rounding to the nearest year, it would take 11 years for the value of the account to reach $70,900.

1)4-2(x + 19) = 50
2)7(x-3)-14=70
Answer:
1. x=4
2. x=15
Step-by-step explanation:
1. Add '-42' to each side of the equation.
42 + -42 + -2x = 50 + -42
Combine like terms: 42 + -42 = 0
0 + -2x = 50 + -42
-2x = 50 + -42
Combine like terms: 50 + -42 = 8
-2x = 8
Divide each side by '-2'.
x = -4
Simplifying
x = -4
2.
Add '35' to each side of the equation.
-35 + 35 + 7x = 70 + 35
Combine like terms: -35 + 35 = 0
0 + 7x = 70 + 35
7x = 70 + 35
Combine like terms: 70 + 35 = 105
7x = 105
Divide each side by '7'.
x = 15
Simplifying
x = 15
