The quadrilaterals ABCD and JKLM are similar. find the length x of MJ

Rina8888 [55]

Answer:

x = 5.6

Step-by-step explanation:

So, lets first go over something:

What does it mean for two shapes to be similar?

It means that all their angles are the same, but their side lengths are different, or in other words, one triangle has a different ratio of side lengths to the other.

So how can we find this ratio difference?

We can take the lengths of the same sime on the two different traingles.

You could go with 4 : 3.2 or 2 : 1.6

When you simplfy this, you get 1 : 0.8

We can then find the value of x by multiplying the two ratios by 7, which is the side length of the similar triangle's unknown side:

7 : 5.6

This means that x = 5.6

Hope this makes sense!

A company introduced a much smaller variant of its tablet, known as the tablet junior. Weighing less than 11 ounces, it was abou

Inessa [10]

Answer:

0.2857

Step-by-step explanation:

Given that a company introduced a much smaller variant of its tablet, known as the tablet junior.

The weight was less than 11 oz. i.e. 50% lighter than std.

Let X be the battery life of the tablet junior

Then X is U(8.5,12)

Mean of X =10.25 hrs

the probability that the battery life for a tablet junior will be 9.5 hours or less

= $P(X\leq 9.5)\\=F(9.5)\\=\frac{9.5-8.5}{12-8.5} \\=0.2857$

I need help its my homework and it's due today Find the base angles.

MrRa [10]

Answer:

Each base angle would be 70°.

Step-by-step explanation:

*Base angles means the two equal angles formed on the base are called base angles.

Base means the third unequal side of the triangle. *

Given triangle is isosceles triangle.

The angle of vertex which is given is 40°.

Let each base angle be x.

We know that,

There are two base angles in a isosceles triangle.

And, Sum of angles of triangle is 180° .

Therefore,

$\tt \implies \: x + x + 40 {}^{ \circ} = 180 {}^\circ$

Now Solve For x. That would be the solution.

Steps:

Combine like terms:

$\tt \implies2x + 40{}^{ \circ} = 180{}^{ \circ}$

Subtract 40 from both sides:

$\tt \implies2x + 40{}^{ \circ} - 40 = 180{}^{ \circ} - 40{}^{ \circ}$

Simplify the LHS and RHS:

$\tt \implies2x + 0 = 140{}^{ \circ}$

$\tt \implies2x = 140 {}^{ \circ}$

Divide both sides by 2:

$\tt \implies \cfrac{2x}{2} = \cfrac{140{}^{ \circ} }{2{}^{ \circ} }$

Use cancellation method and cancel LHS and RHS:

$\tt \implies \cfrac{ \cancel2x}{ \cancel2} = \cfrac{ \cancel{140^{ \circ}} }{ \cancel{2{}^{ \circ} }}$

$\tt \implies \cfrac{1x}{1} = \cfrac{70{}^{ \circ} }{1{}^{ \circ} }$

$\tt \implies{1x} = {70}^{ \circ}$

$\tt \implies{x} = 70{}^{ \circ}$

Hence, each base angle would be 70°.

Verification:

As we know that sum of angles of triangle is 180°.

So,

$\tt \implies \: Base \: angle + other \: base \: angle + vertex \: angle= 180{}^{ \circ}$

We got that one base angles of the given isosceles triangle is 70° and other is 70°, and the vertex angle is 40°[Given].

$\tt \implies70{}^{ \circ} + 70{}^{ \circ} + 40{}^{ \circ} = 180{}^{ \circ}$

Solve it.

$\tt \implies140{}^{ \circ} + 40{}^{ \circ} = 180{}^{ \circ}$

$\tt \implies180{}^{ \circ} = 180{}^{ \circ}$

$\tt \: LHS = RHS$

$\star \sf \: Hence, Verified.$

Factor the expression below

Mazyrski [523]

Answer:

(2x² + 5x + 2) = (2x + 1)(x +2)

Step-by-step explanation:

Given expression is (2x² + 5x + 2).

We have to factorize the given expression.

(2x²+ 5x + 2) = 2x² + 4x + x + 2

= 2x(x + 2) + 1(x + 2)

= (2x + 1)(x + 2)

So the factored form of the given expression will be (2x + 1)(x + 2).
