Step-by-step explanation:

Answer:

The intersection point is (-0.5, -1).

So the x-coordinate is -0.5.

Step-by-step explanation:

Using the elimination method:

2.4x - 1.5y = 0.3

1.6x + 0.5y = -1.3      Multiply this equation by 3:

4.8x + 1.5y = -3.9     Add this equation to the first one:

7.2x  =  -3.6            - note we eliminate the terms in y.

x = -3.6 / 7.2

x = -0.5.

Now plug this into the first equation:

2.4(-0.5) - 1.5y = 0.3

-1.5y = 0.3 + 2.4*0.5

-1.5y = 1.5

y = -1.

Step-by-step explanation:

Using the difference of two squares, the lowest common multiple becomes;

1-sin^2 a

Thus, we have that;

cos a (1-sin a) + cos a (1 + sin a) /1 - sin^2 a

1 - sin^2 a = cos^2 a

That means;

{cos a - cos a sin a + cos a + cos a sin a}/ cos^2 a

= 2cos a / cos^2 a

= 2/cos a

but 1/cos a = sec a

Thus;

2/ cos a = 2 sec a

Answer:

let length be l

breadth=l-10m

area of rectangular park=236m²

Step-by-step explanation:

area of rectangular park=236m²

l×(l-10)=236

l²-10l-236=0

l²-2.l.5+5²-236-5²=0

(l-5)²-236-25=0

(l-5)²=261

(l-5)=√261

(l-5)=16.15

l=16.15+5=21.15

b=l-10=21.15-10=11.15

Probabilities are used to determine the chances of an event. Here, we want to calculate the chances of selecting a junior student. The probability of selecting a junior is 0.44.

From the table, we have:

[tex]Junior = 60[/tex]

[tex]Total = 137[/tex]

So, the probability of Junior is

[tex]P(Junior) = \frac{Junior}{Total}[/tex]

This gives:

[tex]P(Junior) = \frac{60}{137}[/tex]

[tex]P(Junior) = 0.437[/tex]

Approximate

[tex]P(Junior) = 0.44[/tex]

Hence, the probability of selecting a junior is 0.44

Step-by-step explanation:

5. Since rectangle JKLM has two equal diagonals that intersect each other, therefore JN = MN.

If JN = MN therefore:

m<NMJ = m<NJM

Thus:

3x + 38 = 7x - 2

Solve for x. Collect like terms

3x - 7x = -38 - 2

-4x = - 40

Divide both sides by -4

x = 10

✔️Find m<NMJ

m<NMJ = 7x - 2

Plug in the value of x

m<NMJ = 7(10) - 2 = 70 - 2

m<NMJ = 68°

✔️Find m<NML;

m<NML = 90 - 68° (Complimentary angles)

m<NML = 22°

6. Diagonal of a rhombus bisects teach vertex angle, this means that <U is divided into two equal parts. Therefore:

10x - 23 = 3x + 19

Solve for x. Collect like terms

10x - 3x = 23 + 19

7x = 42

Divide both sides by 7

x = 6

✔️Find m<RST:

m<SUT = m<RST (opposite angles of a rhombus are congruent)

Thus,

m<SUT = (10x - 23) + (3x + 19)

Plug in the value of x

m<SUT = (10(6) - 23) + (3(6) + 19)

= (60 - 23) + (18 + 19)

= 37 + 37

m<SUT = 74°

Also, m<RST = 74°

Answer:

Face Value = 8

Place Value = 80

Step-by-step explanation:

What is the difference between face value and place value of 8 in the number 281 ?

First we define Place value and Face Value

Place value

Place value is defined as the digit multiplied wherever it is placed, either by tens, hundreds or thousands.

Face Value

Face value is defined as the digit itself within a number.

Now: we will find face value and place value of 8 in the number 281.

Face Value = 8

Place Value = 8 x 10 (because 8 is at tens place) = 80

So, the answer is:

Face Value = 8

Place Value = 80
