Answer 1

Answer:

Answer:

Given : JKLM is a rectangle.

Prove: JL ≅ MK

Since, by the definition of rectangle all angles of rectangles are right angle.

Thus, In rectangle JKLM,

∠ JML and ∠KLM are right angles.

⇒ ∠ JML ≅ ∠KLM

Since, JM ≅ KL (Opposite sides of rectangles are congruent)

ML ≅ ML ( Reflexive )

Thus, By SAS congruence postulate,

Δ JML ≅ Δ KLM

⇒ JL ≅ MK ( because corresponding parts of congruent triangles are congruent)

Hence proved.

X + 7/8 = 4 A.x = 4 7/8 B.x = 3 1/8 C.x = - 3 1/8 D.x = - 4 7/8

Answers

Simply solve for x to find the answer.
$x + 7/8 = 4Subtract 7/8 from both sides4 - 7/8 = 3.125 3.25 = xx= 3 1/8$

Given that a = 4, b = 3, c = 2, and d = 1, which gives the correct order from least to greatest for the rational numbers on a number line?

Answers

Least to greatest would mean going from the smallest number to the biggest. So it would be d,c,b,a

Final answer:

The correct order from least to greatest for the rational numbers given is d < c < b < a.

Explanation:

To find the correct order from least to greatest for the rational numbers, we need to compare the values of a, b, c, and d.

a = 4 is the greatest rational number.
b = 3 is the second greatest rational number.
c = 2 is the third greatest rational number.
d = 1 is the least rational number.

Therefore, the correct order from least to greatest is d < c < b < a.

Direct variation has this equation:

y = kx

where k is the constant of variation

y = -5 ; x = -15

y = kx
-5 = k(-15)
-5/-15 = k
1/3 = k

Choice D. y = 1/3 x

40 percent of 112.5%

Answers

First 112% is 1.12 divide it by 100 to get .0112 then mutiply it by 40 to get .448 so .448 is the answer. Hope this helps.

a rectangle has an area of 30 square meter and a perimeter of 34 meters. what are the dimensions of rectangle?

Answers

$A=lw$
$P=2l+2w$

$30=lw$
$34=2l+2w$

$30=lw$ --> $w= (30)/(l)$

$34=2l+2( (30)/(l)) \n 34=2l+ (60)/(l) \n 34l=2l^2+60 \n 2l^2-34l+60=0 \n 2(l-2)(l-15)=0 \n l=2, 15$

$30=(2)w$
$15=w$

$30=(15)w$
$2=w$

The dimensions can either be 15 x 2 or 2 x 15.

What is the probability that the first spinner will land on 1 or the second spinner will land on 5?

Answers

The probability that the first spinner will land on a 1 would be 1/3 because their are three numbers on the spinner and only one 'one.'

The probability that the second spinner will land on a 5 is 1/6 because there are 6 numbers on the spinner and only one 5.
