Simplify the following expression:
-13^2=?

Answer:

A. 1.9

B. 3.5

C. 4.2

D. 4.9

I'M KINDA SURE

Step-by-step explanation:

Those images aren't good enough, I can't really get a good look. Basically, if there are nine little lines between each whole number, then each little line represents a tenth of a whole number, or 0.1. If there are four little lines between each whole number, then each little lines is 0.2. So, you just count up from the whole number below the value. For A, start at 1.0 and count up, each little line is 0.1 (if there are nine lines between each whole number), and figure out where A lies. Hope it helped, wish I could give a definite answer.

Answer:

7x7x7x7x7

Step-by-step explanation:

the ⁵ is how many 7 there will be!

Answer:

7x7x7x7x7  

Step-by-step explanation:

If you see a 7^5 it means you need to multiply that number beside the exponent by the number that exponent states.

For example, for this equation 7^5, 5 is the exponent, so you multiply 7 by itself 5 times which is:

7x7x7x7x7

Step-by-step explanation:

Sum is adding so I just did substitution for this. 26+-72=-46 because a positive plus a negative equals a negative.

Answer:

285 I believe

Step-by-step explanation:

109 + (109 + 67) = total

109 + 176 = total

total = 285

A total of 285 tickets were sold for the concert.

The addition operation in mathematics adds values on each side of the operator.

For example 4 + 2 = 6

If 67 more tickets were sold for students than for adults, then the number of student tickets sold can be calculated as follows:

109 adult tickets + 67 = 176 student tickets

So, the total number of tickets sold is:

109 adult tickets + 176 student tickets

Apply the addition operation, and we get

= 285 tickets in total

Therefore, a total of 285 tickets were sold for the concert.

Step-by-step explanation:

Answer:

1.5ft , B  for EDGE2020

Step-by-step explanation:

they are being multiplied by 1.1, so if you divide 1.1 down from 2 three times you get 1.5 roughly.

Using a geometric sequence, it is found that the plant's height on June 1 was of 1.5 ft.

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

In this problem, we have that the first term and the common ratio are given, respectively, by:

[tex]a_1 = 2, q = \frac{2.2}{2} = 1.1[/tex]

Hence the rule for the nth term is given by:

[tex]a_n = 2(1.1)^{n-1}[/tex]

June 1st would be equivalent to three months before the term 1, hence it is the term 1 - 3 = -2, then:

[tex]a_{-2} = 2(1.1)^{-3} = 1.5[/tex]

The plant's height on June 1 was of 1.5 ft.

Step-by-step explanation:

The relation between 5 and 10, is 5 x 2

So you would have to multiply 2 by 2, is 2 x 2 = 4

Or set it up as a proportion

5 / 2 x 10 / x

Cross multiply

5x = 20

Divide

x = 20 / 5

x = 4

Answer:

AC = 0.47 mi

BC = 0.51 mi

Step-by-step explanation:

Notice that we are in the case of an acute triangle for which we know two angles ( < A = 63 and < B = 56) and one side (AB = 0.5).

We can find the measure of the third angle using the property of addition of three internal angles of a triangle:

< A + < B + < C = 180

63 + 56 + < C = 180 degrees

< C = 180 - 63 - 56 = 61 degrees.

Now we use the law of sines to find the length of sides AC  and BC:

[tex]\frac{0.5}{sin(61)} =\frac{AC}{sin(56)}\\AC=\frac{0.5*sin(56)}{sin(61)} \\AC\approx 0.4739\,\,\,mi[/tex]

which can be rounded to two decimals as:

AC = 0.47mi

For side BC we use:

[tex]\frac{0.5}{sin(61)} =\frac{BC}{sin(63)}\\BC=\frac{0.5*sin(63)}{sin(61)} \\BC\approx 0.509\,\,\,mi[/tex]

which can be rounded to two decimals as:

BC = 0.51 mi

have a nice day and can I have brainliest?

Answer:

325.

Step-by-step explanation:

200/x=100/162.5

(200/x)*x=(100/162.5)*x       - we multiply both sides of the equation by x

200=0.61538461538462*x       - we divide both sides of the equation by (0.61538461538462) to get x

200/0.61538461538462=x

325=x

x=325

Answer: XY=21 YZ=29

Step-by-step explanation: okay so the entire line (XZ) is equal to 50, and its made up of a and a + 8. So you can make an equation out of that.

a+a+8=50

2a+8=50

2a=42

a=21

then you just have XY equal 21, and YZ equal 21+8 or 29.

Answer:

XY = 21

YZ = 29

Step-by-step explanation:

XZ = 50

XY = a

YZ = a + 8

XY + YZ = XZ

a + (a + 8) = 50

2a + 8 = 50

2a = 50 - 8

2a = 42

a = 42 ÷ 2

= 21

The mother is 3d older than the daughter

Step-by-step explanation:

Given

Represent the mother's age with m

and

The daughter's age with d

Required

Determine how much older is the mother

First, we need to calculate the mother's age

[tex]m = 4 * d[/tex]

[tex]m = 4d[/tex]

Next, we calculate their age difference

[tex]Age\ Difference = m - d[/tex]

Substitute 4d for m, we have:

[tex]Age\ Difference = 4d - d[/tex]

[tex]Age\ Difference = 3d[/tex]

Hence, the mother is 3d older than the daughter
