Can you guys help me find the answer, I’m in 6th grade?

Answer:

assuming each square equals 1 the answer would be 29

Answer:

411/3 + 388 = 525 -79=446

Step-by-step explanation:

Answer:

x = - 4

Step-by-step explanation:

Given

8x - 3 = 5(2x + 1) ← distribute

8x - 3 = 10x + 5 ( subtract 10x from both sides )

- 2x - 3 = 5 ( add 3 to both sides )

- 2x = 8 ( divide both sides by - 2 )

x = - 4

Answer:

x = - 4

Step-by-step explanation:

8x - 3 = 5(2x + 1)

8x - 3 = 5 × 2x + 5 × 1

8x - 3 = 10x + 5

8x - 10x = 3 + 5

- 2x = 8

2x = - 8

x = (- 8)/2

x = - 4

Thus, The value of x is -4

Answer:

Yes

Step-by-step explanation:

When you're dividing 2 numbers, the order of the negatives doesn't matter. As long as one of the numbers is negative, the result will be negative. Since the order of these numbers are the same (with 3 first and 4 second) they will have the same value.

Answer:

$16

Step-by-step explanation:

If he saves $8 for every $14, he earned $28, which is twice the $14, he will save twice the $8 or $16.

Answer:

A

Step-by-step explanation:

Using Pythagorean theorem (a^2+b^2=c^2) you just plug them in. The hypotenuse is always the longest side so that would be 25. Then it doesn’t matter which side is a or b. 7^2+24^2=625

Then do the square root of 625.

Answer:

[tex]\$50.4[/tex]

Step-by-step explanation:

[tex]As\ we\ given,\\Actual\ cost\ for\ the\ family\ meal= \$ 42\\Additional\ cost\ percent\ to\ the\ meal\ as\ the\ tip=20 \%\\We\ know\ that,\\Additional\ Cost\ for\ the\ tip= Cost\ percent\ of\ the\ tip* Actual\ price\\ of\ the\ meal\\Hence\ by\ substituting\ the\ values,\\Additional\ Cost\ for\ the\ tip=20 \%*42\\Additional\ Cost\ for\ the\ tip=\frac{20}{100} *42\\Additional\ Cost\ for\ the\ tip=\frac{1}{5}*42\\Additional\ Cost\ for\ the\ tip=\$ 8.4\\[/tex]

[tex]Hence,\\Total\ Cost\ of\ the\ dine=Additional\ Cost\ for\ the\ tip+Actual\ Cost\ of\\ the\ meal\\Hence,\\Total\ Cost\ of\ the\ dine=42+8.4=\$50.4[/tex]

Answer:

b. I and II are both false.

Step-by-step explanation:

I. For a significance level, the two tailed hypothesis is not always accurate than the one tailed hypothesis test. The hypothesis testing is carried to find out the correctness of a claim of a population parameter. The two tail hypothesis test which used both positive and negative tails of the distribution is not always more accurate than one tailed test.

II. The process of the point estimation involves the utilization of the values of a statistic which is obtained from the sample data to obtain the best estimate of a corresponding unknown parameter in the given population.

Hence, both the statements are false.

Answer:

The discount rate operated by the coupon is 20%.

Step-by-step explanation:

Since the pair of shoes normally sells for $ 90, but through the application of a discount coupon it sells for $ 72, to determine the discount percentage made by this coupon it is necessary to perform the following calculation:

90 = 100

72 = X

(72 x 100) / 90 = X

7,200 = 90 = X

80 = X

100 - 80 = 20

Thus, the discount operated by the coupon is 20%.

Answer:

Total assets: 110,000

Total liabilities: 70,000

Step-by-step explanation:

Answer:

a. 0.8837

b. 0.6914

c. 10 student

Step-by-step explanation:

a. using markov's inequality; P(u >= X)<= E(u) / X

   mean u = 76

   X, test score = 86

= 76 / 86 = 0.8837

b. variance v = 25

   The test is between 65 and 85 P(65 <= X <= 85);

   P(|65 - X|<= |X - u| <= |85 - X|) = P(65 - 76 <= |X - u| <= 85 -76)

   = P(-11 <= |X - u| <= 9)

   = P(|X - u| <= 9)

using the chebyshev's inequality;

P(|X - u| <= 9) = 1 - variance / (standard deviation of individual test score)^2

   = 1 - 25/ 9^2

   = 1 - 25/81 = 1 - 0.3086 = 0.6914

c. P(|X - 76| <= 5) = 0.9

still using chebyshev's inequality;

= 1 - variance / lower limit^2 (E)

where E = 1 - 0.9 = 0.1

lower limit = 5

= 1 - 25/ 5^2 (0.1) = 10

Answer:

If Clara gets 4 people in 10 phone calls, then she will obviously get 16 people, because there are 40 calls, with 4 people each 10 calls. Meanwhile, with Toby getting 3:8, he will get 15 people in total. 3:8 is equal to 15:40. Clara will have more people in 40 phone calls

Step-by-step explanation:

Step-by-step explanation:

Using Difference of Squares,

16y⁴ - 256x¹²

= 16(y⁴ - 16x¹²)

= 16(y² + 4x⁶)(y² - 4x⁶)

= 16(y² + 4x⁶)(y + 2x³)(y - 2x³).

Answer:

D. $120

Explanation:

P= principal amount, which is $2000 in this case

R= interest rate. In this case, it's 3% per year (or 0.03 in decimal form)

T= time, which in this case is 2.

To find the simple interest, we multiply 2000 × 0.03 × 2 to get 120.

I hope this helped! :)

Answer: 120 is the right answer i think im not sure

Step-by-step explanation:

Answer:

the time period is 9 years

Step-by-step explanation:

The computation of the number of years is as follows:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

$49,000 = $38,000 × (1 + 0.03)^number of years  

$49,000 ÷ $38,000 = 1.03^number of years  

tlog(1.03) = log($49 ÷ $38)

Now apply the log formula in calculator or in excel  

t = log(49 ÷ 38) / log(1.03)

= 8.6

= 9 years

Hence, the time period is 9 years

Answer:

a. 12.5   b. 14

Step-by-step explanation:

If you add all of the scores together (125) and then divide by the the number of scores in the sequence (10), you get 12.5, and then you need to add the 29 on to 125 and divide that by 11, because thats the new amount of numbers in the sequence, to get 14.

Answer:

[tex]A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right][/tex]

Step-by-step explanation:

Given

[tex]T:R^3->R^2[/tex]

[tex]T(e_1) = (1,2)[/tex]

[tex]T(e_2) = (-4,6)[/tex]

[tex]T(e_3) = (2,-6)[/tex]

Required

Find the standard matrix

The standard matrix (A) is given by

[tex]Ax = T(x)[/tex]

Where

[tex]T(x) = [T(e_1)\ T(e_2)\ T(e_3)]\left[\begin{array}{c}x_1&x_2&x_3\\-&&x_n\end{array}\right][/tex]

[tex]Ax = T(x)[/tex] becomes

[tex]Ax = [T(e_1)\ T(e_2)\ T(e_3)]\left[\begin{array}{c}x_1&x_2&x_3\\-&&x_n\end{array}\right][/tex]

The x on both sides cancel out; and, we're left with:

[tex]A = [T(e_1)\ T(e_2)\ T(e_3)][/tex]

Recall that:

[tex]T(e_1) = (1,2)[/tex]

[tex]T(e_2) = (-4,6)[/tex]

[tex]T(e_3) = (2,-6)[/tex]

In matrix:

[tex](a,b)[/tex] is represented as: [tex]\left[\begin{array}{c}a\\b\end{array}\right][/tex]

So:

[tex]T(e_1) = (1,2) = \left[\begin{array}{c}1\\2\end{array}\right][/tex]

[tex]T(e_2) = (-4,6)=\left[\begin{array}{c}-4\\6\end{array}\right][/tex]

[tex]T(e_3) = (2,-6)=\left[\begin{array}{c}2\\-6\end{array}\right][/tex]

Substitute the above expressions in [tex]A = [T(e_1)\ T(e_2)\ T(e_3)][/tex]

[tex]A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right][/tex]

Hence, the standard of the matrix A is:

[tex]A = \left[\begin{array}{ccc}1&-4&2\\2&6&-6\end{array}\right][/tex]
