Step-by-step explanation:

Answer:

It is complicated to answer but there are several factors which contribute toward the difficulty of learning how to solve problems. A person's motivation (anxiety) and poor understanding of the how and why of the material. But there are more internal factors as well, mental and metal learning handicaps. For example, Dyscalculia is a common condition where individuals have issues with making basic calculations and using those numbers the way their peers do. (Dyslexia, ADD/ADHAD, Dysgraphia, and Dyspraxia are other examples.

Answer:

x = -23

y = -17

Step-by-step explanation:

[tex]x = - 6 + y \\ - 7x + 9y = 8 \\ \\ - 7( - 6 + y) + 9y = 8 \\ 42 - 7y + 9y = 8 \\ 2y = 8 - 42 \\ y = \frac{ - 34}{2} \\ y = - 17 \\ \\ x = - 6 + y \\ x = - 6 + ( - 17) \\ x = - 6 - 17 \\ x = - 23[/tex]

Answer:

Step-by-step explanation:

-7(-6 + y) + 9y = 8

42 - 7y + 9y = 8

2y + 42 = 8

2y = -34

y = -17

x = -6 - 17

x = -23

Answer:

121 in² ; 0.840 ft²

Step-by-step explanation:

Given that:

Side length of square tile, s = 11 inches

The Area of a square = a² ;

Where a = side length

Hence, we Can get the area of the square tile using the area of square formula :

Area of square tile = 11² = 121 in²

Area in feets :

1 ft² = 144 in²

x = 121 in²

144 x = 121

x = 121 / 144

x = 0.840 ft²

Answer:

brainliest plzzz

Step-by-step explanation:

2x - y = 7 is in standard form, and if it were slope-intercept form that would help you. I got the y term by itself:

y = 2x - 7 slope-intercept form. You already know the slope of the perpendicular line is the *negative reciprocal* of the slope you have. So that's (-1/2). The perpendicular line is something like

y = -(1/2)x + b and if you substitute 8 for x and 5 for y you get 9 for b.

y = -(1/2)x + 9 is your perpendicular line. In slope-intercept form. To get back to standard form, start by getting rid of fractions. Multiply both sides by 2.

2y = -x + 18 then add x to both sides.

x + 2y = 18 done.

1)

Given the expression

[tex]\frac{5}{7}-\frac{3}{7}[/tex]

Apply the fraction rule:   [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

[tex]\frac{5}{7}-\frac{3}{7}=\frac{5-3}{7}[/tex]

Add the numbers:  [tex]5-3=2[/tex]

          [tex]=\frac{2}{7}[/tex]

2)

Given the expression

[tex]\frac{1}{6}+\frac{3}{6}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

[tex]\frac{1}{6}+\frac{3}{6}=\frac{1+3}{6}[/tex]

Add the numbers:   [tex]1+3=4[/tex]

         [tex]=\frac{4}{6}[/tex]

Cancel 4/6: 2/3

         [tex]=\frac{2}{3}[/tex]

3)

Given the expression

[tex]\frac{1}{2}+\frac{1}{4}[/tex]

Lease common multiplier of 2, 4: 4

Adjust fractions based on LCM

[tex]\frac{1}{2}+\frac{1}{4}=\frac{2}{4}+\frac{1}{4}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

[tex]\frac{2}{4}+\frac{1}{4}=\frac{2+1}{4}[/tex]

Add the numbers:  [tex]2+1=3[/tex]

4)

[tex]\frac{1}{5}+\frac{1}{2}[/tex]

Lease common multiplier of 5, 2: 10

Adjust fractions based on LCM

[tex]\frac{1}{5}+\frac{1}{2}=\frac{2}{10}+\frac{5}{10}[/tex]

Apply the fraction rule:  [tex]\frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}[/tex]

[tex]\frac{2}{10}+\frac{5}{10}=\frac{2+5}{10}[/tex]

Add the numbers: 2+5 = 7

[tex]=\frac{7}{10}[/tex]

5)

Given the expression

[tex]\frac{1}{6}-\frac{1}{8}[/tex]

Lease common multiplier of 6, 8: 24

Adjust fractions based on LCM

[tex]\frac{1}{6}-\frac{1}{8}=\frac{4}{24}-\frac{3}{24}[/tex]

Apply the fraction rule:   [tex]\frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}[/tex]

[tex]\frac{4}{24}-\frac{3}{24}=\frac{4-3}{24}[/tex]

             [tex]=\frac{1}{24}[/tex]

Therefore, we conclude that:

5/7 - 3/7:     B 2/7

1/6+3/6:      C 2/3

1/2+1/4:       E 3/4

1/5+1/2:       D 7/10

1/6-1/8:       A 1/24

Step-by-step explanation:

19 = -23+ 6(2 - p)

19=-23+12-6p

19=-11-6p

6p=-11-19

6p=-30

p= -5

Answer:Solve for p

by simplifying both sides of the equation, then isolating the variable.

Step-by-step explanation: exact form: p= 2/3

                                              decimal form p= 0.6

The points after dilation is (27, 18).

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original.

Enlargements are dilations that result in a larger image. Reduction is the name for a dilatation that shrinks the image. The initial figure is stretched or contracted by a dilatation.

Given:

Scale Factor= 3

Points (9, 6).

If the coordinates is dilated by factor 3.

Then, (9, 6).

= (9(3), 6(3)).

= (27, 18)

Hence, the points after dilation is (27, 18).

Answer:

A sample of 499 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is given by:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In this question, we have that:

[tex]\pi = 0.21[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

How large a sample would be required in order to estimate the fraction of tenth graders reading at or below the eighth grade level at the 90% confidence level with an error of at most 0.03

We need a sample of n, which is found when [tex]M = 0.03[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.03 = 1.645\sqrt{\frac{0.21*0.79}{n}}[/tex]

[tex]0.03\sqrt{n} = 1.645\sqrt{0.21*0.79}[/tex]

[tex]\sqrt{n} = \frac{1.645\sqrt{0.21*0.79}}{0.03}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.21*0.79}}{0.03})^2[/tex]

[tex]n = 498.81[/tex]

Rounding up

A sample of 499 is needed.

Step-by-step explanation:

Perimeter of a semicircle = 0.5πd.

Perimeter of big semicircle = (0.5)(π)(18cm) = 9πcm

Perimeter of 3 small semicircles = (1.5)(π)(6cm) = 9πcm

Hence total perimeter = 9πcm + 9πcm = 18πcm.

Area of a semicircle = 0.5πr²

Area of big semicircle = (0.5)(π)(9cm)² = 40.5πcm²

Area of 3 small semicircles = (1.5)(π)(3cm)² = 13.5πcm².

Hence total area = 40.5πcm² + 13.5πcm² = 54πcm².

Answer:

The value of x = 4 if A, B, and C are collinear points and B is between A and C.

Step-by-step explanation:

We need to find  the value of x if A, B, and C are collinear points and B is between A and C.

We have AB=6x,BC=x−5,AC=23

If points are collinear and B is between A and C we can write:

AC=AB+BC

Putting values and finding value of x

[tex]AC = AB+BC\\23=6x+x-5\\23=7x-5\\7x=23+5\\7x=28\\x=\frac{28}{7}\\x=4[/tex]

The value of x = 4 if A, B, and C are collinear points and B is between A and C.

Answer:

-4 and -2

Step-by-step explanation:

The function has the factors (x + 4) and (x + 2). By setting these both to 0, you will find the zeros of the function.

x + 4 = 0

x = -4

x + 2 = 0

x = -2

Therefore, the zeros of the function are -4 and -2.

[tex]\frac{1}{7}[/tex]

Step-by-step explanation:

We know, that probability of an event E, is [tex]\textrm{P}(\textrm{E})=\frac{\textrm{Number of favorable outcomes}}{\textrm{Total number of outcomes}}[/tex].

Here, there are [tex]7[/tex] days in a week.

So, total number of outcomes [tex]=7[/tex].

And only one day, that is, Friday is selected.

So, number of favorable outcomes [tex]=1[/tex].

Therefore, probability [tex]=\frac{1}{7}[/tex].

Hence, the probability that a randomly selected day of the week will be a Friday [tex]=\frac{1}{7}[/tex].
