Answer:

[See Below]

Step-by-step explanation:

✦ Convert decimal to fraction:

✧ 9.8 = ⁹⁸⁄₁₀

✦ Simplify:

✧ ⁹⁸⁄₁₀ divide 2 on top and bottom = ⁴⁹⁄₅

✧ 49 ÷ 5 = 9 remainder 4 = 9 ⅘

So it'd be 9 ⅘.

The ratio of the measure of the acute angle in a right triangle is 1/2 . Find the measures of the two angles

AleksandrR [38]

30° and 60°.

<h3>Further explanation</h3>

We will solve the problem of the measures of angles in the triangle.

Recall this condition:

The acute angle ⇒ an angle of less than 90°.
The right angle ⇒ an angle of exactly 90°.
A right triangle ⇒ a triangle in which one angle is a right angle.
The interior angles ⇒ the angles inside a triangle.
All the interior angles in a triangle , i.e., $\boxed{ \ \angle A + \angle B + \angle C = 180^0 \ }$

<u>Given that:</u>

The ratio of the measure of the acute angle in a right triangle is ¹/₂.

<u>Question:</u>

Find the measures of the two angles.

<u>The Process:</u>

We call it the triangle ABC. An interior angle inside is a right angle, e.g., ∠A = 90°.

From the ratio of two other acute angles, i.e., 1: 2, we call it ∠B = x and ∠C = 2x.

Let's arrange the three angles in ABC triangle as follows:

$\boxed{ \ 90^0 + x + 2x = 180^0 \ }$

Both sides subtracted by 90°.

$\boxed{ \ x + 2x = 180^0 - 90^0 \ }$

$\boxed{ \ 3x = 90^0 \ }$

Both sides divided by 3.

We get $\boxed{ \ x = 30^0 \ }$

We substitute the value of x back into B and C.

$\boxed{\boxed{ \ \angle B = x\ } \rightarrow \boxed{ \ \angle B = 30^0 \ }} \\\boxed{\boxed{ \ \angle C = 2x\ } \rightarrow \boxed{ \ \angle C = 60^0 \ }}$

We have succeeded in getting the measures of the two angles.

If 6 pears and 5 oranges cost $1.87 and 12 pears and 2 oranges cost $1.90, how much would 3 pears and 3 oranges cost?

Artyom0805 [142]

I'm going to do elimination to find the price of one pear and one orange.
6p +5o =1.87
12p + 2o=1.90
I'm going to multiply the first equation by -2.
-12p-10o = -3.74
12p + 2o =1.90
-8o= -1.84
-1.84÷ -8= .23= o
12p + 2 (.23) = 1.90
12p + .46 = 1.90
12p = 1.44
p=.12
A pear equals .12, while an orange equals .23.
3×.12= .36
.23× 3 = .69
.69 + .36 = 1.05
It would cost $1.05.

( Angle congruence and transformation ) Plz, if anyone can answer these I would appreciate it so much

Answer:

see explanation

Step-by-step explanation:

Since the triangles are similar then the ratio of corresponding sides are equal

(a)

$\frac{AB}{DE}$ = $\frac{BC}{EF}$ , substitute values

$\frac{AB}{17.64}$ = $\frac{6.3}{13.23}$ ( cross- multiply )

13.23AB = 111.132 ( divide both sides by 13.23 )

AB = 8.4

(b)

$\frac{DF}{AC}$ = $\frac{EF}{BC}$ , substitute values

$\frac{DF}{4.1}$ = $\frac{13.23}{6.3}$ ( cross- multiply )

6.3DF = 54.243 ( divide both sides by 6.3 )

DF = 8.61

A jar contains four blue marbles and two red marbles. suppose you choose a marble at random, and do not replace it. then you cho

Sholpan [36]

A) 26.7%
B) 40%

The probability of A is given by 4/6(2/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 red out of 5 remaining.

The probability of B is given by 4/6(3/5), since this is done without replacement; there are 4 blue marbles out of 6. When the first one is gone, there are 2 blue out of 5 remaining.
