Answer:

Option x=-15 and y=15 is correct

Therefore the values are x=-15 and y=15

Step-by-step explanation:

Let A and B be the given matrices

Let [tex]A=\left|\begin{array}{ccc}-20&4&9\\16&0&-6\end{array}\right|[/tex]

and [tex]B=\left|\begin{array}{ccc}-5&-6&0\\1&7&11\end{array}\right|[/tex]

To find the subtraction of the matrix A and B

[tex]A-B=\left|\begin{array}{ccc}-20&4&9\\16&0&-6\end{array}\right|-\left|\begin{array}{ccc}-5&-6&0\\1&7&11\end{array}\right|[/tex]

[tex]=\left|\begin{array}{ccc}-20+5&4+6&9-0\\16-&0-7&-6-11\end{array}\right|[/tex]

[tex]=\left|\begin{array}{ccc}-15&10&9\\15&-7&-17\end{array}\right|[/tex]

Therefore [tex]A-B=\left|\begin{array}{ccc}-15&10&9\\15&-7&-17\end{array}\right|[/tex]

Therefore compare [tex]A-B=\left|\begin{array}{ccc}-15&10&9\\15&-7&-17\end{array}\right|[/tex]=[tex]\left|\begin{array}{ccc}x&10&9\\y&-7&-17\end{array}\right|[/tex]

We get x=-15 and y=15

Therefore the values are x=-15 and y=15

Option x=-15 and y=15 is correct

Step-by-step explanation:

Complementary angles have measures that add to 90°.

ABC and CBD are complementary angles.

Since the angles are complementary, their measures must add to 90°. Set up an equation and solve for n.

n +  18° =  90°

n +  18° −  18° =  90°  −  18°

n =  72°

The measure of the complementary angle is 72°.

Answer:

26

Step-by-step explanation:

25% is 1/4 so 6.50+6.5+6.50+6.50= 26

Answer: 26

Step-by-step explanation: Reading through the problem we have "6.50 is" that's 6.50 =, "25%" 25/100, "of" times, "what number" x.

I changed 25% to 25/100 because "percent" means over 100.

Reducing the 25/100 to 1/4, we have 6.50 = [tex]\frac{1x}{4}[/tex].

Multiplying both sides by 4 to get rid of the fraction, we have 26 = x.

So 6.50 is 25% of 26.

Answer:

Hey, Dalilah. I hope I'm not too late, but the answer is (3,5).

Step-by-step explanation:

You have to use the equation that includes the x value of 3.

4x+1 only includes x values that are less than 3.

2x-1 includes x values that are greater than or equal to 3.

I plugged 3 into both of these equations (4x+1; x < 3 & 2x-1; x ≥ 3) in order to see which equation would've been true.

4(3)+1 = 13; 13 < 3 [False] 13 isn't less than 3 -- and 2(3)-1 = 5; 5 ≥ 3 [True] 5 is greater than or equal to 3.

Since the equation 2(3)-1; 5≥3 is true, you should use this equation. I used Demos in order to graph Y=2(3)-1. At the bottom of that I put x=3, and it showed me (3,5).

I'll post the pictures for proof and better clarification if this is confusing, love.

Answer:

They have to drive  [tex]20\frac{1}{4}[/tex] miles more

Step-by-step explanation:

Given:

Total Distance of the road trip = [tex]32 \frac{3}{4}[/tex] miles

Distance  travelled already = [tex]12 \frac{1}{2}[/tex] miles.

To Find:

How much farther do they have to drive = ?

Solution:

The distance they have to travel farther = Total distance - distance  travelled

The distance they have to travel farther =  [tex]32 \frac{3}{4} - 12 \frac{1}{2}[/tex]

=>[tex]\frac{128 + 3}{4} - \frac{24 +1}{2}[/tex]

=>[tex]\frac{131}{4} - \frac{25}{2}[/tex]

Answer:

Decimals, fractions and mixed units are not integers.

Step-by-step explanation:

Final answer:

Opposite non-integer numbers are pairs like 1/2 and -1/2 or 3.5 and -3.5. These pairs are not integers due to their fractional parts, yet they add up to zero, confirming they are opposites.

Explanation:

When we refer to numbers that are not integers but are opposites, we are seeking pairs of numbers whose sum is zero. Integers are whole numbers such as -1, 0, and 1, which do not include fractions or decimals. On the other hand, rational numbers are ratios of integers like 2/1 or 3/4, and these can be non-integers.

Consider the rational numbers 1/2 and -1/2; these are opposite numbers because they add up to zero. Similarly, another pair could be 3.5 (which is the same as 7/2) and -3.5 (or -7/2). These numbers are not integers because they have fractional parts, yet they are opposites because their sum is zero.

In both cases, these pairs demonstrate the mathematical property that when a number is added to its opposite, the result is always zero, which is a fundamental aspect of additive inverses. This is how we can verify that 1/2 and -1/2, as well as 3.5 and -3.5, are non-integer opposites.

The shoreline will erode approximately 22 7/9 feet in 8 years.

To find the total erosion over 8 years, we can use the given rate of erosion per year. The rate is 2 5/18 feet each year, and to calculate the total erosion over 8 years, we can multiply this rate by the number of years.

[tex]\[ \text{Rate of erosion per year} = 2 \frac{5}{18} \text{ feet} \][/tex]

[tex]\[ \text{Total erosion over 8 years} = \text{Rate of erosion per year} \times \text{Number of years} \][/tex]

[tex]\[ \text{Total erosion} = 2 \frac{5}{18} \times 8 \][/tex]

To perform this calculation, first convert the mixed number into an improper fraction:

[tex]\[ \text{Total erosion} = \frac{41}{18} \times 8 \][/tex]

Multiply the numerators and denominators:

[tex]\[ \text{Total erosion} = \frac{328}{18} \][/tex]

Now, simplify the fraction:

[tex]\[ \text{Total erosion} = 18 \frac{2}{18} \][/tex]

Thus, the shoreline will erode approximately[tex]\(18 \frac{2}{18}\) feet in 8 years, which simplifies to \(18 \frac{1}{9}\) or \(22 \frac{7}{9}\) feet.[/tex]

Answer:

15 crickets; 20 ladybugs

C = G + 10

L= C+5

Step-by-step explanation:

Crickets = C

Ladybugs = L

Grasshoppers = G

We know he found 5 grasshoppers, so:

C = G + 10  --> because he found 10 more crickets than grasshoppers

if we plug in 5 for G (grasshoppers), we can solve for C (crickets):

C= 5+10

15 Crickets

Now that we know he found 15 crickets we can make our second equation:

L= C+5  --> because he found 5 more ladybugs than crickets

if we plug in 15 C (crickets), we can solve for L (ladybugs):

L= 15+5

20 Ladybugs

If Jeff found 5 grasshoppers, the given information leads to two equations showing that he found 15 crickets and 20 ladybugs.

Based on the information given, you can form two equations according to the number of insects Jeff found.

If Jeff found 5 grasshoppers, you can substitute 5 for G in the first equation, which will give you the number of crickets: 5 = C - 10, gives C = 15.

Then, you can substitute C = 15 into the second equation to find the number of ladybugs: 15 = L - 5, gives L = 20.

So, Jeff found 15 crickets and 20 ladybugs.

Final answer:

The land developer can create 60 lots of 1/12 acre each from a 5-acre parcel of land.

Explanation:

The student's question asks how many lots of 1/12 acre each can be created from a 5-acre parcel of land. To find the answer, divide the total acres available (5 acres) by the size of each lot (1/12 acre). Using division for fractions, we invert the divisor and multiply:

5 ÷ (1/12) = 5 × (12/1) = 60

Therefore, the land developer will be able to create 60 lots from the 5 acres.

Answer:

a = 10 cm

Step-by-step explanation:

Area of triangle, A = 51 cm²

base, b = 10.2 cm

Let height of triangle be a cm

Formula:-

[tex]A=\dfrac{1}{2}\times a\times b[/tex]

[tex]51=\dfrac{1}{2}\times a\times 10.2[/tex]

[tex]a=\dfrac{51\times 2}{10.2}[/tex]

hence, the missing length is 10 cm

Answer:

therefore the left over board is 0.216[tex]a^{2}[/tex] where 'a' is length of a side of the black poster board.

Step-by-step explanation:

i) Sasha cuts 4 identical circles from a square piece of black poster.

ii) let each side of the square piece be a.

iii) let us divide the square piece into four equal square parts from which the four identical circles will be cut

iv) therefore the side of each smaller square will be [tex]\frac{a}{2}[/tex].

v) therefore the diameter of each identical circle will be [tex]\frac{a}{2}[/tex]

vi) therefore the radius if each of the four identical circles will be [tex]\frac{1}{2} \times \frac{a}{2} = \frac{a}{4}[/tex]

vii) the area of each of the four identical circles will be = [tex]\pi \times (\frac{a}{4} )^{2} = 3.14 \times (\frac{a}{4}) ^{2} = \frac{3.14a^{2}}{16} = 0.196a^{2}[/tex]

vii) the area of each of the four smaller squares = [tex]\frac{a}{2} \times \frac{a}{2} = \frac{a^{2} }{4} = 0.25a^{2}[/tex]

viii) therefore the area left over from each of the four smaller squares

= 0.25[tex]a^{2}[/tex] - [tex]0.196a^{2}[/tex] = 0.054[tex]a^{2}[/tex]

ix) therefore the left over board is given by 4 [tex]\times[/tex] 0.054[tex]a^{2}[/tex] = 0.216[tex]a^{2}[/tex] where a is length of a side of the black poster board.

Answer:

a)  9n + 10 years.

b) 13n + 10 years.

c) 6n - 9 years

d) 19n + 1 years.

e) 77 years.

Step-by-step explanation:

a) Prince is 6n years old. Jordan's age is (3n + 10) years more than Prince.

So, Jordan's age is (6n + 3n + 10) = 9n + 10 years.

b) The total age of Prince and Jordan will be (6n + 9n + 10) = 13n + 10 years.

c) Kimberly's age is 9 years less than Prince.

So, the age of Kimberly will be 6n - 9 years.

d) The total age of the three people will be (6n - 9 + 13n + 10) = 19n + 1 years.

e) If n = 4, then total age of three people will be 19(4) + 1 = 77 years. (Answer)
