Answer:

Do the same thing for the other exercises and you should find the results. They are all complimentary angles, that means if you sum the two equations representing the angles of each exercise they will be equal to 180º always

Step-by-step explanation:

3. notice 2x is complimentary of 2x + 80 because 2x is opposed to that blank space that compliments it.... I'm bad at explaining, I'll just show.

2x + 2x + 80 = 180

4x + 80 = 180

4x = 180 - 80

4x = 100

x = 25º

so then:

2x = 2*25

2x = 50º

and:

2x + 80 = 50 + 80

2x + 80 = 130º

1. The simplified form of -x + 4 is: B. - x + 4

2. B. 4 less than m

<h3>What is the Commutative Property of Addition?</h3>

According to the Commutative Property of Addition, how numbers that are are added are ordered do not change or affect the sum of the numbers. For example, a + b = b + a.

1. To simplify -(x - 4) using the distributive property:

= -1(x) -1(-4)

= -x + 4

Therefore, the simplified form of -x + 4 is: B. - x + 4

2. m - 4 can be written as a phrase as: B. 4 less than m

3. The property that illustrates the expression, 3 + x = x + 3, is: D. cumulative property of addition.

4. Irrational numbers cannot be expressed, as a simple fraction. √3 cannot be expressed in simple fractions. Therefore, √3 is classified as: B. irrational.

Find the quotient.<br><br>5 over 7 divided by 7 over 10

raketka [301]

Answer:

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

Step-by-step explanation:

$\frac{5}{7}\div \frac{7}{10}$

$\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}$

$=\frac{5}{7}\times \frac{10}{7}$

$\mathrm{Multiply\:fractions}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}$

$=\frac{5\times \:10}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:5\times \:10=50$

$=\frac{50}{7\times \:7}$

$\mathrm{Multiply\:the\:numbers:}\:7\times \:7=49$

$=\frac{50}{49}$

Therefore,

$\frac{5}{7}\div \frac{7}{10}=\frac{50}{49}$

What is the volume of the square pyramid with base edges 32 mm and slant height 34 mm?

leonid [27]

Answer:

V = 10,240mm^3

Step-by-step explanation:

The volume of pyramid is given by the following formula:

$V=\frac{1}{3}bh$ (1)

b: base of the pyramid = (32mm)^2

h: height

Thus, it is necessary to find the value of h, by using the Pitagoras's theorem, one half of the base and the slant height (which forms a rectangle triangle with h):

$h=\sqrt{(34)^2-(16)^2}=30mm$

by replacing in (1) you obtain:

$V=\frac{1}{3}(32mm)^2(30mm)=10,240\ mm^3$

hence, the volume is 10240mm^3
