Step-by-step explanation:

S is in the interior of ∠RQT. m∠RQS=(4x-20)°,m∠SQT=(3x+14)°, and m∠RQT=155°

Answers

Step-by-step explanation:

Since we are not told what to look for, we can as well look for the value of x, m∠SQT and m∠RQS

Given

m∠RQS=(4x-20)°

m∠SQT=(3x+14)°

m∠RQT=155°

The addition postulate is true

m∠RQT= m∠RQS + m∠SQT

Substitute the given parameters into the formula

155 = 4x-20+3x+14

155 = 7x-6

7x = 155+6

7x = 161

x = 161/7

x = 23

Solve for m∠RQS

m∠RQS = 4x-20

m∠RQS = 4(23)-20

m∠RQS = 92-20

m∠RQS = 72°

Solve for m∠SQT

m∠SQT = 3x+14

m∠SQT = 3(23)+14

m∠SQT = 69+14

m∠SQT = 83°

Find two consecutive integers whose product is 12 more than the square of the smaller
number.

Answers

Answer: The product of two consecutive even numbers is 12 more than the square of the smaller number. The product of the numbers is 6 and 8 is 48. Square of the smaller number (here 6) is 36. so, 12 + 36 = 48.

Answer:

2x6/4=3

Step-by-step explanation:plz mark brainliest

Answer:

The answer is 1/12

Step-by-step explanation:

Divide: 2/6 : 4 = 2/6 · 1/4= 2 · 1/6 · 4 = 2/24 = 2 · 1 / 2 · 12 = 1 /12

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 4/1 is 1/4) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step , cancel by a common factor of 2 gives 1/12

In words - two sixths divided by four = one twelfth.

[tex]Area = 180m^2[/tex]

[tex]Width = Length - 8[/tex]

Required

Determine the Length and the Width

Represent Width with W and Length with L;

So, we have:

[tex]Area = L * W[/tex]

[tex]Area = L * (L - 8)[/tex]

[tex]180 = L * (L - 8)[/tex]

[tex]180 = L^2 - 8L[/tex]

[tex]L^2 - 8L - 180 = 0[/tex]

Expand

[tex]L^2 - 18L + 10L- 180 = 0[/tex]

[tex]L(L - 18) + 10(L- 18) = 0[/tex]

[tex](L + 10)(L- 18) = 0[/tex]

Split

[tex]L + 10 =0[/tex] or [tex]L - 18 = 0[/tex]

[tex]L = -10[/tex] or [tex]L = 18[/tex]

But length cant be negative:

So,

[tex]L = 18[/tex]

Recall that:

[tex]Width = Length - 8[/tex]

[tex]W = 18 - 8[/tex]

[tex]W = 10[/tex]

Hence:

[tex]Length = 18m[/tex]

[tex]Width = 10m[/tex]

The dimension of the rectangular garden is 8m by 10m

The formula for calculating the area of the rectangular garden is expressed as;

A = lw

l is the length

w is the width

If the width of the garden must be 8 meters less than the length, then;

w = l - 8

Substitute into the formula;

180 = l(l-8)

180 =l^2 - 8l

l^2-8l - 180 = 0

Factorize the result;

l(l+10)-8(l+10) = 0

(l-8)(l+10)=0

l = 8 and -10

Since A = lw

w = A/l

w = 180/8

w = 10

Hence the dimension of the rectangular garden is 8m by 10m

Answer:

[tex]\mu_{x} = 0.8[/tex]

[tex]\sigma = 0.095 [/tex]

The shape of this sampling distribution is approximately normal

Step-by-step explanation:

From the question we are told that

The population proportion is [tex]p = 0.8[/tex]

The sample size is n = 100

Generally the expected value of this sampling distribution is mathematically represented as

[tex]\mu_{x} = p = 0.8[/tex]

Generally the standard deviation of this sampling distribution is mathematically represented as

[tex]\sigma = \sqrt{ \frac{p(1- p )}{n } } [/tex]

=> [tex]\sigma = \sqrt{ \frac{0.8 (1- 0.8 )}{100 } } [/tex]

=> [tex]\sigma = 0.095 [/tex]

Generally given that the sample is large (i.e n > 30 ) and the standard deviation is finite then the shape of this sampling distribution is approximately normal

B. 2 C. 1/6 D. -1/2

Answers

Answer:

D. -1/2

Step-by-step explanation:

When a line is perpendicular to another line the slope will be the exact opposite. For example line A = y = 3x + 5 the line perpendicular to it will be -1/3x.

So -1/2 is the slope of your perpendicular line.
