Answer:

Explanation:

acb − (a + d)

= (-2) (-12) (3) - (-2 + -4)

Parenthesis: (-2 + -4) = -6

= (-2) (-12) (3) - (-6)

Simplify (-2) (-12) (3): 72

72 - (-6)

if a=−2 , b=3 , c=−12 , and d=−4 for expression  acb−(a+d) then its value is 78.

An expression is combination of variables, numbers and operators.

The given expression is acb−(a+d)

a times c times b minus a plus d

The values of a, b, c and d are given.

In the given expression a,b,c and d are variables and plus and minus are operators

a=−2 , b=3 , c=−12 , and d=−4 .

Substitute these values in expression acb−(a+d)

(-2)(-12)(3)-(-2+(-4))

When minus is multiplied two times we get positive, if three times we get negative

72-(-2-4)

72-(-6)

Seventy two plus six

72+6

Seventy eight

78

Hence if a=−2 , b=3 , c=−12 , and d=−4 for expression  acb−(a+d) then its value is 78.

Answer:

Step-by-step explanation:

Question (1)

x² + 10x + 12

= x² + 2(5x) + 5² - 5² + 12

= [x² + 2(5x) + 5²] - 5² + 12

= (x + 5)² - 25 + 12 [Since, a² + 2ab + b² = (a + b)²]

= (x + 5)² - 13

Question (2)

y² - 6y - 15

= y² - 2(3y) - 15

= y² - 2(3y) + 3² - 3² - 15

= [y² - 2(3y) + 3²] - 3² - 15 [Since, a² - 2ab + b² = (a - b)²]

= (y - 3)² - 3²- 15

= (y - 3)² - 9 - 15

= (y - 3)² - 24

Step-by-step explanation:

Let's solve for x.

2x+5y=3

Step 1: Add -5y to both sides.

2x+5y+−5y=3+−5y

2x=−5y+3

Step 2: Divide both sides by 2.

2x/2

[tex]\boxed{\textsf{ Hence the percentage probability of getting a not odd is \textbf{ 50\% }.}}[/tex]

Step-by-step explanation:

Given that we roll a 6 sided dice . We need to find the probability that the outcome is not a odd number . So , when we roll a dice then the possible outcomes are ,

[tex]\sf\implies Sample\ space = \{ 1,2,3,4,5,6 \}[/tex]

And the total number of possible outcomes is 6 . That is ,

[tex]\sf\implies n(Sample \ space )= 6 [/tex]

Now the total number of non odd numbers that is even numbers is 3 ( 2 , 4 & 6) .

[tex]\sf\implies n(Outcomes_{(even)})= 3 [/tex]

Now , lets use the formula of Probability that is ,

Probability :-

[tex]\qquad\boxed{\boxed{\sf P = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes }}}[/tex]

Now put on the respective values :-

[tex]\sf\implies P( getting\ a \ not \ odd ) = \dfrac{Total \ number \ of \ favourable\ outcomes }{Total \ number \ of \ possible\ outcomes } \\\\\sf\implies P( getting\ a \ not \ odd ) =\dfrac{3}{6} \\\\\sf\implies \boxed{\sf P( getting\ a \ not \ odd ) = \dfrac{1}{2} }[/tex]

[tex]\rule{200}2[/tex]

Expressing the probability as percentage :-

[tex]\sf\implies \% \ of \ getting \ non \ odd = Probability \times 100 \\\\\sf\implies \% \ of \ getting \ non \ odd = \dfrac{1}{2}\times 100 \\\\\sf\implies \boxed{\pink{\frak{ \% \ of \ getting \ non \ odd = 50\%}}}[/tex]

Answer:

-4y=40

y=-10

x-3(-10)=17

x-30=17

x=17+30

x=47

Step-by-step explanation:

Answer:

x= 5

y= -4

Step-by-step explanation:

x= 17+3y so you substitute what you got for x in so

17 +3y +7y = -23

10y=-40

y=-4 now you put -4 in for y in the first equation

x = 17 + (3 times -4)

x = 17 - 12

x=5

Answer:

14) 9.2  15) 12.9

Step-by-step explanation:

14) cos(52) = x/15

x = 15cos(52)

x = 9.2349

x = 9.2

15) cos(22) = 12/x

x = 12/cos(22)

x = 12.9424

x = 12.9

Since there is no number in the thousandths place which would make the number in the hundredths place round up or down, we keep the number the same:

Answer:

Rise over Run.

Step-by-step explanation:

If it's on a line on a graph you count how many it goes up until it's aligned with the next point and then you count how ever many over until it hits it. So it could be 2 up and 4 over making the slope 2/4.

Answer:

only Katie is right

Step-by-step explanation:

first, find the nth rule using the equation n = a + (n - 1)d

a = first term (here, it's 22)

n = the position of a term

d = the constant difference between each term (here, it's -5 since each term reduces by 5)

put these in and then simplify:

n = a + (n - 1)d

n = 22 + (n - 1)(-5)

n = 22 - 5n + 5

n = -5n + 27

this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!

Answer:

m > 12

Step-by-step explanation:

I) Find what m is in 1/4m = 3:

1/4m = 3

Divide by 1/4:

m = 12

II) Make an inequality:

m > 12

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.

Ratio is the quantitative relation between two amounts showing the number of times one value contains or is contained within the other.

The ratio of Fiji apple to Gala apple = 160 : 120 = 4 : 3

If 30 new gala trees are planted, hence the number of gala trees increases to 150 (120 + 30). To maintain the same ratio:

Number of fiji apple = (4/3) * 150 = 200

New Fiji apple trees = 200 - 160 = 40

The number of new Fiji apple trees needed to maintain the same ratio is 40 trees.
