Only the second row is equal. The first row can't be equal because it says -2=-1/2

This is what I think:

#1: 800 - 50 = 750

#2: 800 divided by 2 = 400 - 50 = $350

i think the dryer costs 450$ and the washer 350$

Answer:

It's true that  [tex]JK \cong MN[/tex]

Step-by-step explanation:

If the lengths of two line segments are equal, then they are said to be congruent to each other.

[tex]JK[/tex] has endpoints as [tex]J(-1, 10)[/tex], [tex]K(-5,2)[/tex] and [tex]MN[/tex] has endpoints as [tex]M(9,-7), N(1,-3)[/tex]

Formula for finding the length of line segment: [tex]\sqrt{(x_{1}-x_{2})^2+(y_{1}-y_{2})^2}[/tex] , where [tex](x_{1}, y_{1})[/tex] and [tex](x_{2}, y_{2})[/tex] are two endpoints.

So, the length of [tex]JK = \sqrt{(-1-(-5))^2+(10-2)^2}= \sqrt{(4)^2+(8)^2}= \sqrt{16+64}= \sqrt{80}[/tex]

and the length of [tex]MN=\sqrt{(9-1)^2+(-7-(-3))^2}= \sqrt{(8)^2+(-4)^2}= \sqrt{64+16}= \sqrt{80}[/tex]

As, the lengths of [tex]JK[/tex] and [tex]MN[/tex] are equal, so we can say that, [tex]JK[/tex] is congruent to [tex]MN[/tex].

To determine if JK is congruent to MN, use the distance formula to find the lengths of the line segments. If the lengths are equal, then the segments are congruent.

To determine if JK is congruent to MN, we need to compare the lengths of these line segments. The formula for finding the length of a line segment with endpoints (x1, y1) and (x2, y2) is the distance formula: d = sqrt((x2 - x1)^2 + (y2 - y1)^2).

Since the lengths of JK and MN are equal (sqrt(80) = sqrt(80)), we can conclude that JK is congruent to MN.

72 ÷ 6 = 12 and 12 × 36 = 432 and 72 × 36 = 2,592 and 2,592 ÷ 6 = 432

You have 2x^2 + 9x -9 and 3x^2 -2x +14

To find total area add the two polynomials together by combining the like terms.

2x^2 + 3x^2 = 5x^2

9x + -2x = 9x-2x = 7x

-9 + 14 = 5

Total area = 5x^2 + 7x + 5

The formula for area of this shape is (a+b)/2 * h

a = 8

b= 12

h = 6

Area = (8+12)/2 * 6

Area = 20/2 * 6

Area = 10 * 6

Area = 60 sq. m.

Answer:

8y^3z

Step-by-step explanation:

8, y^3 and z are common to both expressions.  Thus, the GCF is 8y^3z.

53√2

using the ' law of radicals '

√a × √b = √ab

simplifying the radicals

√200 = √( 100 × 2 ) = √100 × √2 = 10√2

√162 = √( 81 × 2 ) = √81 × √2 = 9√2

8(10√2 - 3(9√2) = 80√2 - 27√2 = 53√2

The first option is the right answer

Range are the y-values. Plug the x-values into the equation and solve for y.

f(x) = 3x - 2

f(-1) = 3(-1) - 2

     =   -3  - 2

     = -5

f(0) = 3(0) - 2

     =   0  - 2

      = -2

R: -5 ≤ y < -2   ⇒   [-5, -2)

********************************

f(x) = 2x + 3

f(0) = 2(0) + 3

     =   0  + 3

     =    3

f(5) = 2(5) + 3

      =  10 + 3

      =  13

R: 3 ≤ y < 13    ⇒  [3, 13)

Now, put them together:  [-5, -2) U [3, 13)

Answer: A

If it were 3:00 precisely then it would be 90 degrees.

The minute hand moves 360 degrees per hour so 5 minutes makes it 30 degrees closer to the hour haned.

The hour hand moves 360 degrees per 12 hours (720 minutes) so 5 minutes make it move 2.5 degrees further from the minute hand.

90 degrees -30 degrees + 2.5 degrees = 62.5 degrees

Answer:

30° angle between the minute and the hour hands, when they show 3:05 PM.

Step-by-step explanation:

Given  : 3:05 PM

To find :  What is the measure of the angle between the minute and the hour hands.

Solution : We have given clock that showing time 3:05 PM

We know that clock make the complete angle that is 360 degree.

We know 1 hour = 60 minute.

So, angle formed by 60 minute  = 360 °.

Angle formed by 1 minute = [tex]\frac{360}{60}[/tex].

Angle formed by 1 minute = 6°.

According to question :

At 3:05 pm

Total minute between minute hand and hour hand is 5.

So. Angle formed by 5 minute = 5 * 6 .

Angle formed by 5 minute = 30° .

Therefore, 30° angle between the minute and the hour hands, when they show 3:05 PM.

Answer: Leticia won the first round

==============================================================

Your teacher is basically asking "which value is further from zero on the number line?". The value -19 is 19 units away from zero; while 21 is 21 units away from zero.

See the attached image below. Each "space" is a distance of 1

Absolute value measures distance along the number line. Distance is never negative. In terms of notation, you would say

|-19| = 19 and |21| = 21

The outputs 19 and 21 are then compared. We see that 21 is larger, so therefore, Leticia has the higher score and she won the first round.

The answer you want would be C.52

Reason: 32+5= 37 that is the 1st and 2nd term. 37+5=42 thatis the 3rd term. 42+5=47 that's the 4th term. And 47+5=52 that's the 5th term.

(3y +10) /4 = 2y

Multiply both sides by 4:

4(3y +10) = 4(2y)

12y +40 = 8y

Subtract 40 from each side:

12y = 8y -40

Subtract 8y from each side:

4y = -40

Divide both sides by 4:

y = -40 / 4

y = -10

The answer is A. -10

Because the 2 triangles are similar, find the ratio of 2 known sides.

Side XY = 10

Side AB = 25

25 / 10 = 2.5

This means the larger triangle is 2.5 times larger than the smaller one.

Now find the side of the smaller triangle, that would be the same side as X on the larger triangle and multiply that by 2.5.

XZ is the same side as AC

So X = 6 x 2.5

X = 15

i bleieve the answer is 1796

Out of 4041 students in a school where 5/9 are girls, the number of boys in the school will be 1796.

In this mathematics problem, we are looking to find the number of boys in a school where we know the total number of students (4041) and the proportion that are girls (5/9). To start, you can determine the number of girls in the school by multiplying the total number of students by the proportion of students that are girls (4041 * 5/9 = 2245). Taking this number of girls away from the total number of students gives us the number of boys: 4041 - 2245 = 1796. So, out of 4041 students, 1796 of them are boys.

If you divide 7 by 2 it equals 3.5 meaning each game is 3.5 dollars.  So you can find how much any number of games would be by using this equation g (3.5) = c  For example, if there were 3 games then you would do 3 (3.5) = c and the cost would be 10.5 dollars.  

Final answer:

The relationship between the cost and the number of games bowled can be represented by the equation c = 3.5g, where c is the total cost and g is the number of games bowled.

Explanation:

To determine the relationship between the cost (c) and the number of games (g) bowled, we need to find a formula that connects these two quantities based on the information provided. Given that bowling two games costs $7 and bowling four games costs $14, we can see that the cost is directly proportional to the number of games bowled. This means for every game bowled, there is a fixed rate being paid.

Let's break down the information given:

2 games = $7

4 games = $14

From this, we can see that each game costs $3.50 because $7 divided by 2 equals $3.50. Therefore, the relationship between the cost and the number of games can be represented by the equation:

c = 3.5g

Where c represents the total cost and g represents the number of games bowled. This equation can be used to calculate the cost for any number of games bowled.

-1 C, that's the only logical answer I can think of. Or does it have to be in F?

The change in temperature is a decrease of 1°C, which is calculated by subtracting the initial temperature from the final temperature.

The question involves calculating the change in temperature from -3°C to -4°C. To find the change in temperature, you subtract the initial temperature from the final temperature. In this case, the change would be:

-4°C - (-3°C) = -4°C + 3°C = -1°C.

So the change in temperature is a decrease of 1°C.

Answer: n has two distinct prime factors 2 and 3.

Step-by-step explanation:

As given the smallest composite number such that it can be written as the product of two positive integers that differ by 10.

i.e. if first number be x then the other number be x+10 and n=x(x+10), where n must be composite number.

So after putting the values of x by positive integer

1) x=0 then n=0(10+0)=0...which is not a composite number.

2) x=1 then n=1(1+10)=11..... which is not a composite number.

3)x=2 then n=2(2+10)=24......which is a composite number.

so our n=24 and we know that 24=2×2×2×3

Therefore its distinct prime factors are 2 and 3.

Answer:

2

Step-by-step explanation:

Solution:

The smallest pair of numbers that differ by 10 is 1 and 11; however, they multiply to 11 which is not composite. We try the next pair up: 2 and 12, which multiply to 24 which is composite, so [tex]$n=24$[/tex].  [tex]$24$[/tex]  factors as [tex]$2^3 \cdot 3$[/tex], so it has [tex]$\boxed{2}$[/tex] prime factors: 2 and 3.
