Answer:

[tex]x\leq -3[/tex]

Step-by-step explanation:

We have been given a compound inequality. We are supposed to solve our given inequality.

[tex]-7x+1\geq 22\text{ or }-10x+41\geq 81[/tex]

First of all, we will solve both of our given inequalities separately, then we will combine the solution of both inequalities.

[tex]-7x+1-1\geq 22-1[/tex]

[tex]-7x\geq 21[/tex]

we know dividing or multiplying inequality by a negative number flips inequality.

[tex]\frac{-7x}{-7}\leq \frac{21}{-7}[/tex]

[tex]x\leq -3[/tex]

[tex]-10x+41\geq 81[/tex]

[tex]-10x+41-41\geq 81-41[/tex]

[tex]-10x\geq 40[/tex]

[tex]\frac{-10x}{-10}\leq \frac{40}{-10}[/tex]

[tex]x\leq -4[/tex]

Upon merging overlapping intervals, the solution for our given inequality would be [tex]x\leq -3[/tex].

Answer:

20%

Step-by-step explanation:2.8-3.5 then divide that by 3.5 and multiple the answer by 100 to get the percent

Answer: 20%

Step-by-step explanation:

According to the  zookeeper ,

The predicted weight of the newborn lion = 2.8 pounds

The actual weight of the newborn lion = 3.5 pounds

Now , the zookeepers's percent error = [tex]\dfrac{|Predicted-actual|}{actual}\times100[/tex]

[tex]=\dfrac{|2.8-3.5|}{3.5}\times100\%\\\\=\dfrac{|-0.7|}{3.5}\times100\%\\\\=\dfrac{0.7}{3.5}\times100\%\\\\=\dfrac{100}{5}\%=20\%[/tex]

Hence, the zookeepers's percent error = 20%.

Answer: 1) A. 41% (2)B. 0.15

(3) C. 560%

Step-by-step explanation:

In question 1, all you need to do is to count the number of shaded box, and tho total boxes are 100, so number of shaded box/100

=41/100 = 41%

In question (2)

15/100,whenever you shift a decimal to the left hand side the zero will go away, so shiftingit twice to the left handside,the two zeros will go away, so you will have 0.15

In question3

5.6 to percentage,

Simply multiply by 100/100

5.6 ×100/100 = 560/100 =560%

Complementary angles add up to 90 degrees.

The complement angle to 35 is:

90 - 35 = 55 degrees.

The answer is D.

Answer:

The diameter of the circle is 9.

Step-by-step explanation:

Because circumference is equal to [tex]\pi[/tex] * d, we can backtrack and use this equation to find diameter. Let's say [tex]\pi[/tex] is equal to 3.14.

28.26 = 3.14d

Divide both sides by 3.14.

9 = d

The diameter of the circle is 9.

To find the diameter of a circle with a circumference of 28.26 units, the formula D = C / π is used, yielding a diameter of approximately 9 units.

The student's question pertains to finding the diameter of a circle when the circumference is given. The circumference (C) of a circle is related to the diameter (D) by the formula C = πD, where π (pi) is approximately 3.14159. Given that the circumference of the circle is 28.26 units, we can solve for the diameter by rearranging the formula to D = C / π.

Substituting the given circumference into the formula gives us:

D = 28.26 units / 3.14159

When we do this calculation, we find that the diameter is approximately 9 units. Therefore, the diameter of the circle is approximately 9 units.

Answer:

195 cm

Step-by-step explanation:

Total the number of players and their total heigh

number of players = 2 + 6 + 3 + 1 + 1 = 13

total height = (2 × 200) + (6 × 201) + (3 × 202) + 203 + 204

                   = 400 + 1206 + 606 + 203 + 204 = 2619 cm

let x be the height of the new player, then

[tex]\frac{2619+x}{14}[/tex] = 201 ( multiply both sides by 14 )

2619 + x = 14 × 201 = 2814 ( subtract 2619 from both sides )

x = 2814 - 2619 = 195

height of new player is 195 cm

A regular or equilateral triangle has all sides of equal length. The length of each side can be found by dividing the total perimeter by the number of sides. Hence, each side of the triangle is 17 meters long.



The question is asking about the sides of a regular triangle, which is another name for an equilateral triangle. In an equilateral triangle, all sides are of equal length. The perimeter of a triangle (or any polygon) is just the sum of the lengths of all its sides. So, if the perimeter of the regular triangle is 51m, that means the total length of all three sides is 51m. Since all three sides are of equal length, we can find the length of each individual side by dividing the total perimeter by the number of sides. In this case, 51m divided by 3 sides equals 17m. Therefore, each side of the regular triangle is 17 meters long.

Answer:

The hypotenuse of this is 6

Step-by-step explanation:

Answer:

hypotenuse = 6

Step-by-step explanation:

For a right triangle, we know that sin (theta) = opposite / hypotenuse

sin 45 = 3 sqrt(2)/ hypotenuse

Multiply both side by hypotenuse

hypotenuse * sin 45 = 3 sqrt(2)

Divide by sin 45 on both sides

hypotenuse * sin 45/ sin 45 = 3 sqrt(2)/sin 45

hypotenuse = 3 sqrt(2)/sin 45

hypotenuse = 6

Answer:

3/7 and 4/17

Step-by-step explanation:

a) given that Shen is playing a game and the probability of unlocking the treasure test is 3/10.

To find the odds in favour of his character unlocking the treasure chest.

Since probability = 3/10 we have favourable and total are in the ratio 3:10

i.e. favourable:Favourable+unfavourable= 3:3+7

Hene odds= favourable:unfavourable =3/7

Answer is 3/7

b) Given that odds against choosing a blue block are 13/4

This means there are 4 blue blocks and 13 other colour blocks.

Total blocks= 13+4 =17

No of blue blocks = 4

Probability of selecting blue block=4/17

Answer:

Absolute value is the distance away from zero, so if x is a rational number and y is opposite, they would both be the same distance away from zero, regardless of their sign.  

Step-by-step explanation:

Absolute value is the distance of a number away from zero.  For example, if x is equal to the rational number -2, the absolute value of -2 is just 2, given that both 2 and -2 are only a distance of 2 away from the number zero.  Think of it as your walk or drive to school.  If you live 4 miles from school, you drive a distance of 4 miles there and 4 miles back.  That distance is not calculated as a positive 4 miles there and a negative 4 miles back, but rather just 4 miles there and 4 miles back, for a total distance of 8 miles.  So, if x=4 and y=(-4), the absolute value of both would be 4.

Answer:

454.50

Step-by-step explanation:

Answer:

Y = 3 X + (-8)

Step-by-step explanation:

The given equation  is in  the slope intercept form

Equation is

                 Y - 4 = 3 (X - 4)

In a linear function → it takes number X as a input and gives mX + b as output.

m and b are constant.

mX → it is called scaling by factor m.

   +b → it is called a shift by an amount b.                  

Then we can say that linear function looks like this

f(X) = mX + b

Let Y = f(X)

Hence,

           Y = mX + b

From the given equation

                                         Y - 4 = 3 (X - 4)

                                          Y - 4 = 3 X - 12

                                           Y = 3 X + (-8)                                (m = 3 , b = - 8)

It is the linear form of the given equation

Answer:

10 2/15 hours

Step-by-step explanation:

If we have a candle that is 11 2/5 inches tall

It burns 1 1/8 inches per hour.  We need to divide to see how long the candle will last

11 2/5 ÷ 1 1/8

I will convert the mixed numbers to improper fractions

11 2/5 = (5*11+2)/5 = 57/5

1 1/8 = (8*1+1)/8 = 9/8

57/5 ÷ 9/8

Copy dot flip

57/5 * 8/9

456/45

Now we change it back to a mixed number

45 goes into 456  10 times with 6 left over

10 6/45

This simplifies to 10 2/15
