Answer 1

∠CAB +∠ CBA +∠ ACB = 180°

Sum of all angle of triangle is 180° ..

75 + 75 + ∠ACB = 180°

∠ACB = 180° - 150°

∠ACB = 30°

Now ,

x = ∠ACB ( being vertically opposite angle)

x = 30°

Answer 2

The angle measure of x is 30°.

What is a Triangle?

The polygon known as a triangle has three sides and three vertices.

The triangle's total angle is 180 degrees.

Given that a triangle has 2 known angles measuring 75° and 75°.

Let the third missing angle measure is y.

And y and x are opposite angles in the diagram.

So, x = y.

The sum of all the interior angle measures of a triangle is 180°.

So, 75 + 75 + y = 180

y = 180 - 150

y = 30°

So x = y = 30°

Therefore, x = 30°.

The average grain of salt is 0. 0003 meters wide. Rhinovirus, which causes the common cold, is 0. 00000003 meters wide. How many times wider is a grain of salt than Rhinovirus? Choose the correct answer. A. 1 × 102 times B. 1 × 103 times C. 1 × 104 times D. 1 × 105 times

Answers

Number of times a grain of salt is wider than Rhinovirus

= width of average grain of salt / width of rhinovirus

=0.0003 / 0.00000003

=1 × 10^4

Hence, the number of times a grain of salt is wider than Rhinovirus is 10,000 times.

"Evaluate the expression.
78 - 2^4 ÷ (14 - 6) x 2"
please explain how you get your answer.
thanks

Answers

Answer:

equal to 74

Step-by-step explanation:

To evaluate the expression, we will follow the order of operations (PEMDAS):

Start with the exponent: 2^4 = 16Next, evaluate the division: 14 - 6 = 8Then, divide 16 by 8: 16 ÷ 8 = 2Next, multiply the result by 2: 2 x 2 = 4Finally, subtract 4 from 78: 78 - 4 = 74

So the expression 78 - 2^4 ÷ (14 - 6) x 2 is equal to 74.

Let’s use pemdas or bodmas
Let’s solve separately first

2^4 = 2’s power 4 = 2*2*2*2 = 16
14-6 = 8
2” = 2*2 = 4

78 - 16 / 8 * 4
= 78 - 2 * 4
= 78 - 8 = 70

Answer:

100%

Explanation:

To find percent increase, you first have to find the difference between the two values.

16 - 8 = 8

Next, you divide this new answer by the original value.

8 ÷ 8 = 1

Finally, you multiply by 100 to find your percent increase.

1 × 100 = 100%

1.55°C each hour. If the temperature at midnight was
−
7
−7°C, what was the temperature at 2:00 am?

Answers

Answer:

-3.90

Step-by-step explanation:

1) 1.55+1.55 =3.10

2) -7+3.10= (-3.90)

The answer is -3.9 degrees Celsius because 1.55+1.55=3.10 (We do this because 1h= +1.55 so 2h = +3.10) and then we do -7+3.10= 3.90 degrees Celsius (we do this because we do the initial temperature plus the temperature risen in 2 hours)

Does 6/10+8/100 = 14/10 or 68/10??

Answers

Answer:

The answer is 68/100 or 17/25

Step-by-step explanation:

To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25

Together, teammates Pedro and Ricky got 2685 base hits last season. Pedro had 281 more hits than Ricky. How many hits did each player have?

Answers

Answer:

1,483 is the answer

Answer:

Step-by-step explanation:

Let's say Pedro got x hits

and Ricky got y hits.Given,Pedro and Ricky together got 2685 hits.So, the

equation will be as (x+y)=2685................eq (1)

Given,Pedro had 281 more hits than Ricky.So the equation looks like

x=281+y..........eq(2).

substitute eq(2) in eq(1).We get,

2685=(281+y)+y

2685=281+2y

2685-281=2y

2404=2y

2404/2=y

y=1202

substitute y=1202 in eq(2).We get,

x=1202+281

x=1483

So,Pedro hit 1483 and Ricky hit 1202

Answer: hope this helps ♡

Jack will be twice as old as his sister in -8 years.

Step-by-step explanation:

If Jack could age backwards, he would be twice as old as his sister in -8 years.

Jack = 12

Amy = 2

2*2 (Amy) = 4

12 - 8 = 4 (we got 8 by subtracting amy's age from jack's age: 12-2=8)
