Answer:

12 number for theanswer of that question answer

Answer:

(10t + u)(10u + t) = 4,930

100tu + 10t^2 + 10u^2 + tu = 4,930

101tu + 10t^2 + 10u^2 = 4,930

10t^2 + (101u)t + (10u^2 - 4,930) = 0

(101u)^2 - 4(10)(10u^2 - 4,930)

= 10,201u^2 - 400u^2 + 197,200

= 9,801u^2 + 197,200

We see that u = 5 gives 442,225.

√442,225 = 665

(10t + 5)(50 + t) = 4,930

500t + 10t^2 + 250 + 5t = 4,930

10t^2 + 505t - 4,680 = 0

2t^2 + 101t - 936 = 0

t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)

= (-101 + √17,689)/4

= (-101 + 133)/4 = 32/4 = 8

So the numbers are 58 and 85.

58 + 85 = 143

Answer:

\(\frac{3}{4}\) or A

Step-by-step explanation:

There are 6 containers that weigh \(\frac{6}{8}\) lbs.

\(\frac{6}{8}\)x\(\frac{6}{6}\)

\(=\frac{6*6}{8*6}\)

\(=\frac{36}{48}\)

\(=\frac{36/12}{48/12}\)

\(=\frac{3}{4}\)

The answer is \(\frac{3}{4}\) which is option A.

Hope this helps! Please let me know if you need more help, or if you think my answer is incorrect. Brainliest would be MUCH appreciated. Have a great day!

Answer:

37.5

Step-by-step explanation:

cosФ = \(\frac{A}{H}\)

cos(33°35') = \(\frac{m}{45}\)

m = 45 × cos(33°35')

m = 37.5 (1d.p.)

Answer:

525

Step-by-step explanation:

If it's just asking to find the average of heads then times it by 20 then just do 32+28+21+24 to get 105 and divide it by 4 to get 26.25 then times it by 20 since this is the average of 50 throws and it's asking for the average of 1,000 throws which is 525

Answer:

You have to go clockwise and 90 degrees and the rest is self explanatory. Hope I helped.

Step-by-step explanation:

The required transformation of the polygons ABCD to  A'B'C'D'  is 7 units right and a clockwise orientation.

Given that,
Each graph shows two polygons ABCD and A'B'C'D'. In each case, To describe a sequence of transformations that takes ABCD to A'B'C'D'.

A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,

Examples of the polygon, equilateral triangle, square, pentagon etc

Here,
Polygons ABCD is at the left side of the y-axis and after transformation is shifted to the right of the y-axis by 7 units as the Location of Point A and the Location of point B' is 7 units apart. And is also oriented to 90° clockwise.

Thus, the required transformation of the polygons ABCD to  A'B'C'D'  is 7 units right and a clockwise orientation.

Answer:

7.5

Step-by-step explanation:

I think I may be wrong but 15/2 equals 7.5

Answer:

For A: The first function has a greater ROC

For B: The first function has a negative slope

Step-by-step explanation:

Explication for A:

We already know that the R.O.C. (slope) is 2 for the first function, so all we need to do is substitute the values in the table into the following formula: y2-y1/x2-x1

after substituting: (-3-(-6))/(0-(-1))

simplify 3/1=3, since the ROC is 3, the second equation has a greater ROC than the first

Explanation for B:

The first function described is f(x)=20-3.5x

This is because the y intercept is the starting point, or how much money she has in the gift card. She spends 3.5 dollars per week, so we add a variable to represent the number of weeks, and its negative since she is spending, not earning. We also know that the slope is negative since y is decreasing as x is increasing, on the table.

The second function described is c(m)=5x+10

This is because the equation represents the total cost of renting a calculator, so both terms are positive.

i hate math sooooooooooo much

Answer:

A. t > 2.5

Step-by-step explanation:

If she wants to achieve more than 590, we already know the sign would be greater than (>).

All we have to do is divide 590/236, which gives us 2.5.

Therefore, she will have to ride more than 2.5 hours to reach her goal, t > 2.5

Answer: Range and mean = 8 of both

variance of Set X= 4.7

variance of Set Y= 4.6

Step-by-step explanation:

Two sets of data, set X and set Y are given

a.) Range is the difference of the highest value and the lowest value,

Therefore, Range of set X = 12-4=8

Range of set Y = 12-4=8

Now, Mean of a given data set is the average of all the terms present in the given data set

Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8

Mean of set Y= (4+5+7+32+20+12)/10= 8

Therefore, both the data sets has same range and mean.

b.) Standard deviation tells about the variability of the date and is given by,

S.D= σ = √∑ ( X − μ )^2/n

S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7

S.D of set Y= √(16+9+1+0+4+16)/10= √4.6

Variance is the square of S.D, that is, σ^2

Therefore, variance of set X=4.6

variance of set Y= 4.7

c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Answer:

0.00998 Inches

Step-by-step explanation:

Thickness of the light bulb filament = 0.01 Inch

Allowable error = 2%.

2% of 0.01 = 0.02 X 0.01 =0.0002 Inch

Therefore, the allowable thickness of the bulb filament

We can then calculate the least allowable thickness of the filament as:

The least allowable thickness of the filament is 0.00998 Inches.

Answer:

C. 0.0098

Explanation:

one-hundredth of an inch: 1/100 ≈ 0.01 (inch)

Upper-bound (maximum error):

= 0.01 × (100% + 2%)

= 0.01 × 102%

= 0.0102 inches

Lower-bound (minimum error):

= 0.01 × (100% - 2%)

= 0.01 × 98%

= 0.0098 inches

Hence, the greatest allowable thickness of filament is 0.0102 inches and mostly the least allowable thickness is 0.0098 inches, which is the answer.

Answer:

12,000 times

Step-by-step explanation:

The probability of selecting an orange marble in each individual selection is given by:

P(Orange) = Number of orange marbles / Total number of marbles

P(Orange) = 3 / 8 = 0.375

To determine the best prediction for the number of times you will pick an orange marble, we can multiply the probability of selecting an orange marble by the total number of selections:

Best prediction for the number of times you will pick an orange marble = P(Orange) * Total number of selections

Best prediction for the number of times you will pick an orange marble = 0.375 * 32,000

Best prediction for the number of times you will pick an orange marble = 12,000

Therefore, the corrected best prediction possible for the number of times you will pick an orange marble is also 12,000.

Step-by-step explanation:Quadrant I and Quadrant IV

Two out of the four Quadrant planes have a positive x- value.

The coordinate axis split the plane into four parts called Quadrants or which can also be called Cartesian quadrants. These divided parts of the plane are numbered I, II, III, and IV.

The first quadrant/ quadrant I which lies on the upper axis on the right side of the plane has two positive quadrants, that is one positive x and one positive y because both of them lie in the positive direction of the axis.

The second quadrant/ quadrant II which appears on the upper right side of the plane has one positive and one negative coordinate that is, one positive y and one negative x because the x coordinate lie in the opposite direction of the sign of the numbers.

In quadrant III which lies in the downward direction and the left side of the plane has two negative coordinates both x and y. both the coordinates go towards the opposite direction of the sign convention.

in the last quadrant/ quadrant IV have a positive x- coordinate and one negative y-coordinate. Because the y coordinate goes against the positive sign convention.

Answer:

D. 89%

Step-by-step explanation:

To calculate the average, we need to add all the grades together and divide by 4. So, we can plug in each number to find which one will give us 80%. So, if we plug in 89, and add it to 82, 75, and 75, we get 320. Then, divide it by 4, which gives us 80, and our desired average.
