Whitney and Destiny hung out at the mall on Saturday. They spent 45 minutes shopping for clothes and 1 hour at the food court. Then they spent 30 minutes at the video arcade before heading home. It was 12:45 P.M. when Whitney and Destiny left the mall. What time did they start shopping for clothes?

Given that

In a Parallelogram CARS ,∠C = (5x-20)°

∠A = (3x+20)°

angle C and angle A are adjacent angles

We know that

In a Parallelogram the adjacent angles are supplementary.

⇛∠C + ∠A = 180°

⇛ (5x-20)°+(3x+20)° = 180°

⇛5x°-20°+3x°+20° = 180°

⇛(5x°+3x°)+(20°-20°) = 180°

⇛8x°+0 = 180°

⇛8x° = 180°

⇛ x° = 180°/8

⇛ x° = 22.5°

Answer:-The value of x = 22.5°

Answer:

90%

Step-by-step explanation:

N125 = 2x + N100

2x = N25

x = N12.5

camera = N100 + N12.5 = 112.5

Total = N125

(Camera/Total) x 100 = % spent on camera

(112.5 / 125) x 100 = 90%

Answer:

A(t) = amount remaining in t years

= A0ekt, where A0 is the initial amount and k is a constant to be determined.

Since A(1690) = (1/2)A0 and A0 = 80,

we have 40 = 80e1690k

1/2 = e1690k

ln(1/2) = 1690k

k = -0.0004

So, A(t) = 80e-0.0004t

Therefore, A(430) = 80e-0.0004(430)

= 80e-0.172

Solution: For finding QR we need to apply Pythagoras Theorem

What is Pythagoras Theorem ?

ans : Pythagoras Theorem is the sum of square of two sides which is equal to the third side or the hypotenuse. This formula is valid oy incase of Right-Angled Traingle because one of three angles here is 90°

According to this law let's apply it in the diagram shown here.

After factorising both of them we get

So, QR is √(16x² - 14x + 3)

The expression 4xy is added to the equation 5xy to get 9xy​.

A collection of constants, variables connected using one or more arithmetic operator is called an expression

Example = 4y, 3x+4.

Two algebraic expressions separated by an equal symbol in between them and with the same value of the expression are called equations.

Example = 2x +4 = 12

Here, 4 and 12 are constants and x is variable

The equation can be solved as:

Let t be added to the following equation,

5xy + t = 9xy

Subtract 5xy  from both the sides,

t = 9xy​ - 5xy

t = 4xy

Thus, 4xy is added to 5xy to get 9xy.

Step-by-step explanation:

Because we have parallel lines, we can use alternate angles are equal. Therefore, we know that 11x-6 = 10x.

Minus 11 from both sides, and we get -6 = -x, so x = 6

-0.5 is greater than -0.64

We need to find the symbol -0.64 ,0-0.5. -0.64<0-0.5.

A number system is defined as a system of writing to express numbers.

We need to find which symbol is used between Minus zero point six four and minus zero point five.

-0.64 and -0.5

As we know that the integers are number with positive, Negative and zero.

-0.64<-0.5

On the number line the integer -0.64 lies on left of -0.5.

So -0.64 is less than -0.5.

Hence -0.64 is less than -0.5.

Answer:

<1 = 50

<2 = 130

Step-by-step explanation:

<1 and 130 are supplementary angles

<1 + 130 = 180

<1 =180-130

<1 = 50

130 and <2 are corresponding angles and corresponding angles are equal when the lines are parallel

<2 = 130

Step-by-step explanation:

Well first we can say measure angle 2 equals 130° because they are S.s.int.ext angles, (same side interior angles and exterior). Or also corresponding

Now with measure angle 1, it is a supplementary angle

Let 1 stand for measure angle 1

[tex]130 + m1 = 180[/tex]

Subtract 130° from both sides

[tex]m1 = 50[/tex]

In the question, the probability of getting the given number of success

from a specified number of trials is required.

The correct probability function to use is the binomial probability function.

Reasons:

The given parameters are;

The probability of success = 0.06

The number of trials = 15 trials

The probability of interest = The probability of two successes in 15 trials

Solution;

The required probability is given by the following binomial probability

distribution formula;

[tex]P(x) = \dbinom{n}{x}\cdot p^x \cdot q^x = \mathbf{\dfrac{n!}{(n - x)! \cdot x!} \cdot p^x \cdot q^x}[/tex]

Where:

n = Number of trials

x = Number of required success

p = Probability of a success

q = Probability of one failure = 1 - p

For the question, we get;

[tex]P(x) = \dfrac{15!}{(15 - 2)! \times 2!} \times 0.06^2 \times (1 - 0.06)^{15 - 2} \approx \mathbf{0.169}[/tex]

Answer:

y = -4x + 28

Step-by-step explanation:

yeah-ya........ right?

Step-by-step explanation:

what is the standard form for your teacher ?

because that is absolutely not agreed on worldwide (and even between teacher and teacher in the same region).

there are 2 main forms :

the general slope intercept form is

y = ax + b

a is the slope. and is here -4.

b is the y-intercept (the point, where the line crosses the y-axis, meaning the y value when x=0).

we get b by using the point coordinates in the half finished equation :

4 = -4×6 + b = -24 + b

28 = b

so, the equation is

y = -4x + 28

the general slope point form is

y - y1 = a(x - x1)

where a (often called m) is again the slope, and x1, y1 are the coordinates of a given point.

so, we have

y - 4 = -4(x - 6)

Answer:

Step-by-step explanation:

First, we add 16 and 28 [tex]16+28=44[/tex]

Now we have to solve for x

We know we have to do parenthesis first so [tex](4+7)=11[/tex]

[tex]44=x(11)[/tex]

Then we divided both sides by 11

[tex]\frac{44}{11} =\frac{11x}{11}[/tex]

[tex]x=4[/tex]

To find the Prime Factorisation of 84 we have to divide 84 by the smallest prime number which is 2

So [tex]\frac{84}{2} = 42[/tex]

Since 42 is an even number we can still divide it by 2

So [tex]\frac{42}{2} = 21[/tex]

Now we can divide 21 by the 2nd smallest prime number which is 3

So [tex]\frac{21}{3} = 7[/tex]

So the prime factors of 84 would be [tex]2*2*3*7[/tex] or [tex]2^2*3*7[/tex]
