Answer: B or 52 degrees...

Step-by-step explanation:

Congruent means to have identical properties and because triangle PQR is congruent to triangle STU, their angles are also congruent.

In the theorem AAA, angle P is congruent to S, angle Q is congruent to T and angle R is congruent to U.

The sum of the angles in a triangle is 180 degrees and so you would do 180-86-42 which would get you to 52 degrees and that is the answer.

From -2 to 0 there is 2, but from  1 to 3 there is also 2, so 2/2=1

4/5 of the homework = 5/6 hr

1/4 of the homework = 5/6 ÷ 4

5/5 of the homework = 5/6 ÷ 4 × 5

5/6 ÷ 4 × 5 = 25/24 hrs which is 1 and 1/24 of an hr

answer: 1 and 1/24 of an hr

Answer: 1. 1,024. 2. 148,828,125. 6. 1. 7. 1.

Step-by-step explanation:

1. 2 x 2 x 2 x 2 x 2 x 2 = 64.

2 x 2 x 2 x 2 = 16.

64 x 16

1,024.

2. 5 x 5 x 5 = 125.

5 x 5 x 5 x 5 x 5 x 5 x 5 x 5 = 390,625.

125 x 390,625

48,828,125.

6. c x c x c x c x c x c x c = 1.

c x c = 1.

Step-by-step explanation:

t=(-2.74 + sqrt(2.74^(2)-4*-4.9*(-10))) / -2*-4.9

t=(-2.74 + sqrt(7.5076-4*+49))/9.8

t=(-2.74 + sqrt(7.5076+45))/9.8

t=(-2.74 + sqrt(52.5076))/9.8

t=(-2.74/9.8)+(sqrt(52.5076))/9.8

this is simplest form, next will be rounded answers

t=0.45981763305

Answer:

no real solutions

see below

Step-by-step explanation:

It looks like a quadratic formula

t= -2.74 + sqrt(2.74^(2)-4*-4.9*(-10)) -: 2*-4.9

[tex]t = \frac{-2.74 +\sqrt{2.74^2 - 4*(-4.9)*(-10)} }{2*(-4.9)}[/tex]

[tex]t = \frac{-2.74 + \sqrt{7.5076 -196} }{-9.8} = \frac{-2.74 + \sqrt{-188.4924} }{-9.8}[/tex]

[tex]t = \frac{-2.74 + 13.73i}{-9.8 }[/tex]

i = [tex]\sqrt{-1}[/tex]

Part A: A  

Part B: A

Step-by-step explanation:

1)

the inequality should be less than or equal to, since we need to find how many are left

now, the answer B is wrong, since there can't be negative 56, since Xander collected some cans, though he still must collect a few

thus, the answer is A

2)

A again is correct, since it represents:c ≤ 56

B represents c ≥ 56

C represents c ≤ –56

D represents c ≥ -56

Answer: 2 marbles

Step-by-step explanation:

Look at the scale. On the right there are 3 less squares. But there are more marbles! So, if you subtract three marbles (the ones that would make it equal to the left) and divide the marbles by 3 squares, you get 2!

PLEASE MARK BRAINLIEST

Answer:each box should weigh as much as 2 marbles

Step-by-step explanation:

On the first side of the scale theres a 5 next to the box and im assuming that means that there are 5 boxes on the first side of the scale. 5 boxes that each weigh 2 marbles + the 3 marbles that are already there =  13 marbles total

On the second side of the scale there are 9 marbles and 2 boxes. 2 boxes that each weigh 2 marbles + 9 marbles that are already there = 13 marbles total

So the scale will be balanced because there is 13 on each side

Answer: false

Step-by-step explanation:

The exponents would have to have a different sign from each other (positive or negative), not the integer.

Answer:

D. 2

Step-by-step explanation:

We know that y=2x-3. We want to find out what the value of x is when y=1. Therefore, we can substitute 1 in for y in the equation.

Equation: y=2x-3

Substitute 1 in for y: 1=2x-3

Now, solve for x.

1=2x-3

3 is being subtracted from 2x. The inverse of subtraction is addition. Add 2 to both sides.

1+3=2x-3+3

1+3=2x

4=2x

x is being multiplied by 2. The inverse of multiplication is division. Divide both sides by 2.

4/2=2x/2

4/2=x

2=x

The correct answer is D. 2

Answer:

[tex]T_n = \left \{ {{T_1=2} \atop {T_n =-5T_{n-1}}} n>1 \right.[/tex]

Step-by-step explanation:

Given

Geometric sequence: 2, -10, 50, -250

Required

Recursive formula of the sequence

We start by naming each sequence

[tex]T_1 = 2\\T_2 = -10\\T_3 = 50\\T_4 = -250[/tex]

Represent each term in relation to the previous term (except T1)

[tex]T_1 = 2\\T_2 =2 * -5\\T_3 = -10 * -5\\T_4 = 50 * -5[/tex]

Recall that

[tex]T_1 = 2\\T_2 = -10\\T_3 = 50\\T_4 = -250[/tex]

So, at this point; we have to make substitutions

[tex]T_1 = 2\\T_2 =T_1 * -5\\T_3 = T_2 * -5\\T_4 = T_3 * -5[/tex]

Subtract 1 from each term on the right hand side

[tex]T_1 = 2\\T_2 =T_{2-1} * -5\\T_3 = T_{3-1} * -5\\T_4 = T_{4-1} * -5[/tex]

Replace each term greater than 1 by n

[tex]T_1 = 2\\T_n =T_{n-1} * -5\\T_n = T_{n-1} * -5\\T_n = T_{n-1} * -5[/tex]

Remove repetition

[tex]T_1 = 2\\T_n =T_{n-1} * -5[/tex]

[tex]T_1 = 2\\T_n =-5T_{n-1}[/tex]

Hence, the recursive formula is

[tex]T_n = \left \{ {{T_1=2} \atop {T_n =-5T_{n-1}}} n>1 \right.[/tex]

Answer:

610 cm²

Step-by-step explanation:

This is an irregular figure. We can split it up by the triangle and the rectangle on the bottom.

To find the area of the triangle, we must determine the base length. As we can see, the bottom of the arrow has the measure 15 cm, and you can see that the missing section in the base of the triangle is the same measure. Now we find the measure of the base by adding 15 + 8 + 8, which equals 31 cm.

Now we multiply and divide by 2 to find the area of the triangle:

20*31 * 1/2

= 310 cm²

Now, we find the area of the rectangle. We can see that its dimensions are 15 by 20. We can plug these values into the rectangle formula:

A = 15*20

A = 300 cm²

Now we add these values to find the total area:

310 cm² + 300 cm²

= 610 cm²

Answer:

B. Each part of the whole fraction bar is equal to one-seventh.

C. The shaded portion of the fraction bar represents a unit fraction.

E. Each part represents a unit fraction.

Step-by-step explanation:

The answer is B because, there are 7 parts to the diagram, which means each part is equal to 1/7. So each part is a unit fraction, and 1/7 can represent the shaded part, and since it is a unit fraction, C. can also apply.

Hope this helps! Have a great day!

Answer:

7

Step-by-step explanation:

To find the answer, consult the worst case. The worst thing that can happen is Dorothy selects the 5 white balls first. Now, only red balls remain. Since Dorothy can only select red balls, the first 2 balls she will pick will be red. 5+2=7. Dorothy must select 7 balls to be sure she has at least 2 red balls.

The number of balls that Dorothy must select to be sure she has at least two red balls is 6.

To be sure Dorothy has at least two red balls, we need to consider the worst-case scenario where she selects all the white balls before selecting any red balls.

Since there are 5 red balls and 5 white balls, the probability of selecting a red ball on the first draw is 5/10 or 1/2. If Dorothy selects a white ball on the first draw, the probability of selecting a red ball on the second draw is 5/9 since there will be 5 red balls and 9 balls in total remaining in the bowl.

In the worst-case scenario, Dorothy selects all 5 white balls first, so she needs to draw at least 6 balls to be sure she has at least two red balls. This is because on the sixth draw, there will be 5 red balls and 4 white balls left in the bowl, ensuring that she gets at least two red balls.

Therefore, the number of balls Dorothy must select is at least 6 balls to be sure she has at least two red balls.

Answer:

The second possible answer is the correct one.

Step-by-step explanation:

The second possible answer is the correct one.  As x increases, 4^x increases exponentially.  However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward.  Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.

Answer:

x = 12

Step-by-step explanation:

If it is a perpendicular bisector, then the intercepting angles are always 90°.

If that is the case then we simply set the expression 7x + 6 equal to 90 and solve for x. We should get 12 as our answer.

Answer & Step-by-step explanation:

The first thing we must do is gather the information from the problem. We are given that there are 38 boys and 22 girls which makes a total of 60 children in all.

38 + 22 = 60

We are also given that out of 60 children, 33 of these children have vouchers which leaves 27 children who don't have vouchers.

60 - 33 = 27

Lastly, we are given that twice as many boys as girls do not have vouchers. So, we have to find two numbers that add together to 27 but one of those numbers have to be half of the other number. These number are 9 and 18.

9 + 18 = 27

18 / 2 = 9

So, 27 children do not have vouchers which include 18 boys and 9 girls.

Now that we know this, we can subtract the number of girls without vouchers to the total number of girls. We will also do the same for the boys.

Girls: 22 - 9 = 13

Boys: 38 - 18 = 20

So, 33 children have vouchers which include 20 boys and 13 girls.
