Donnavan is measuring the angles of a triangle. He measures the first two angles and gets 10° and 120°. What should be the measure of the third angle?

Answer:

35/6

Step-by-step explanation:

The result of dividing 5/6 by 1/7 is 35/6.

Here, we have,

To divide fractions, we can use the following rule:

To divide one fraction by another, we multiply the first fraction by the reciprocal of the second fraction.

In this case, we have:

(5/6) ÷ (1/7)

To find the reciprocal of a fraction, we simply flip the fraction by swapping the numerator and denominator.

Therefore, the reciprocal of 1/7 is 7/1.

Now, we can rewrite the expression as a multiplication:

(5/6) * (7/1)

Multiplying the numerators and denominators:

(5 * 7) / (6 * 1)

Simplifying:

35/6

Therefore, the result of dividing 5/6 by 1/7 is 35/6.

Step-by-step explanation:

One negative one positive

Hope it helped

Answer:

[tex]\boxed {a = 6}[/tex]

Step-by-step explanation:

Solve for the value of [tex]a[/tex]:

[tex]3 - 6a = 9 - 6a[/tex]

-Take [tex]-6a[/tex] and add it to [tex]-6a[/tex]:

[tex]3 - 6a + 6a = 9 - 6a + 6a[/tex]

[tex]3 - a = 9[/tex]

-Subtract both sides by [tex]3[/tex]:

[tex]3 - 3 - a = 9 - 3[/tex]

[tex]\boxed {a = 6}[/tex]

Therefore, the value of [tex]a[/tex] is [tex]6[/tex].

Answer:

x= -16

Step-by-step explanation:

-2x+5=37

-2x=37-5

-2x=32

x= -16

Answer:

x= -16

Step-by-step explanation:

The goal in this problem is to get X on one side by itself.

We know that the opposite of subtraction is addition and the opposite of multiplication is division.

so to get 5 over to the right side, we need to subtract.

-2x+5=37 >>-2x= 37-5= 32

your problem now reads -2x= 32

We still have -2 on the left side and we need it to go to the right side so that X is by  itself. The opposite of multiplication is division, so we will need to divide

-2x=32÷-2 >> x=-16

Answer:

[tex]\huge\boxed{\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%}[/tex]

Step-by-step explanation:

Two ways.

1. Convert to the decimal:

[tex]\dfrac{4}{7}=4:7=0.\overline{571428}\\\\\dfrac{5}{8}=5:8=0.625\\\\0.7=0.7\\\\72\%=\dfrac{72}{100}=0.72[/tex]

therefore

[tex]0.\overline{571428}<0.625<0.7<0.72}[/tex]

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

2. Convert to the fractions with common denominator.

[tex]\dfrac{4}{7};\ \dfrac{5}{8}\\\\0.7=\dfrac{7}{10}\\\\72\%=\dfrac{72}{100}=\dfrac{18}{25}[/tex]

[tex]LCD=7\cdot8\cdot5\cdot5=1400\\\\\dfrac{4}{7}=\dfrac{4\cdot200}{7\cdot200}=\dfrac{800}{1400}\\\\\dfrac{5}{8}=\dfrac{5\cdot175}{8\cdot175}=\dfrac{875}{1400}\\\\0.7=\dfrac{7}{10}=\dfrac{7\cdot140}{10\cdot140}=\dfrac{980}{1400}\\\\72\%=\dfrac{72}{100}=\dfrac{72\cdot14}{100\cdot14}=\dfrac{1008}{1400}\\\\\dfrac{800}{1400}<\dfrac{875}{1400}<\dfrac{980}{1400}<\dfrac{1008}{1400}[/tex]

therefore

[tex]\dfrac{4}{7};\ \dfrac{5}{8};\ 0.7;\ 72\%[/tex]

Answer:

1,890.8cm

Step-by-step explanation:

Sine law!! So drawing the triangle helps, We know that the angle n is 10 because 180 - 10 -160 =10. Knowing that you can now use the sine law.

x/sin160 = 960/ sin 10

x= sin 160 (5528.4)

Answer:

This is really simple, here i'll explain:

Step-by-step explanation:

41.2 x 1.5=

count how many spaces are after the decimal point.

for example, 41.2 has 1 space after the decimal point. The decimal 1.5 also has 1 space after the decimal point. So if you add the spaces it would be 2 because 1 + 1 = 2

After that, take away the decimal point, and just multiply like you normally would.

412 times 15

this would be 6180

after you do the multiplication, you will add the decimal point.

The decimal point will go in between 1 and 8 because there were 2 spaces after the decimal point in the numbers, and if you add them it would be 2 spaces.

Hope this helps!

Answer:

41.2×1.5=61.8. because you always have to line up the decimals.

Answer:

(4,5)

Step-by-step explanation:

Answer:

(4, 5) because you have to move the coordinate y (2) up 3 times.

Step-by-step explanation:

f(x) = 2x^2 - 7x + 3

f(0) = 2(0)^2 - 7(0) + 3

= 0 + 0 + 3

= 3

f(x) = 2x^2 - 7x + 3

f(-2) = 2(-2)^2 - 7(-2) + 3

= 8 + 14 + 3

= 25

Answer:

s14.98 + 92

Step-by-step explanation:

In order to make an expression for this word problem, all you have to do is follow along the steps in the problem:

s14.98 represents how many shorts Michele bought and how much they cost

8 * 11.50 represents how many shirts she bought and what they cost, but we need to simplify, so

8 * 11.50 = 92

Therefore, by adding the shorts and shirt together, we get the expression:

s14.98 + 92

D

Step-by-step explanation:

The solution is, the value of x is, D) x ≤ -30.

An inequality is a relation which makes a non-equal comparison between two numbers or mathematical expressions.

here, we have,

given that,

x + 20 ≤ -10

now, we have to solve this,

at first we subtract 20 from both sides, we get,

x + 20 - 20  ≤ -10 -20

or, x  ≤ -30

Hence, The solution is, the value of x is, D) x ≤ -30.

Answer: 28

-9^2 - (-6)^2 + 3 - 20

so follow order of operations

P = parentheses

E = exponents

D = divide

M = multiply

A = add

S = subtract

since there are no parentheses, do exponents

-9^2 = 81

-6^2 = 36

so now its

81 - 36 + 3 - 20

now follow order of operations

81 - 36 = 45

45 + 3 - 20

3 - 20 = -17

45 + -17 = 28

so your answer is 28
