(Help me with this test question) Lines l and m are intersected by transversal t and l || m. Lines l and m are vertical with l to the left of m. Transversal t intersects them both slanting down and right. The angles formed above t with l and m from left to right are angles 1, 3, 5, and 7. The angles formed below t with l and m from left to right are angles 2, 4, 6, and 8. Select all the angles that are supplementary to ∠1. Group of answer choices ∠3 ∠4 ∠6 ∠5 ∠7 ∠8

Answer:

13

Step-by-step explanation:

Step 1:

50 + 3x = 7x - 2      Equation

Step 2:

50 = 4x - 2      Subtract 3x on both sides

Step 3:

52 = 4x    Add 2 on both sides

Step 4:

x = 52 ÷ 4      Divide

Answer:

x = 13

But the question you asked i think you have add and stuff

Given parameters:

Elevation of Town M = 282ft

Elevation of Town R = 679ft

Unknown:

How much higher is Town R than M = ?

Solution:

Town M lies below the sea level whereas Town R is above the sea level.

     Graphically:

                                    Town R   679ft

                                         ↑

                                         ↑

                                         ↑

                                         ↑

                                    ↔↔↔  Sea level

                                         ↓

                                         ↓

                                    Town M     282ft

Town R is 282ft + 679ft higher than Town M  = 961ft

Answer: The number of first-year residents she must survey to be 95% confident= 263

Step-by-step explanation:

When population standard deviation ([tex]\sigma[/tex])  is known and margin of error(E) is given, then the minimum sample size (n) is given by :-

[tex]n=(\dfrac{z^*\sigma}{E})^2[/tex], z* = Two-tailed critical value for the given confidence interval.

For 95% confidence level , z* = 1.96

As, [tex]\sigma[/tex] = 8.265, E = 1

So, [tex]n= (\dfrac{1.96\times8.265}{1})^2 =(16.1994)^2\\\\= 262.42056036\approx263\ \ \ [\text{Rounded to the next integer}][/tex]

Hence, the number of first-year residents she must survey to be 95% confident= 263

Answer:

D. 3 Points

Step-by-step explanation:

Given

[tex]Members = 3[/tex]

[tex]Point = 9 - n[/tex]

[tex]1 \leq\ n \leq 8[/tex]

Required

Determine the least possible score

The least point a member of a team can get is when n = 8.

i.e.

[tex]Point = 9 - n[/tex]

[tex]Point = 9- 8[/tex]

[tex]Point = 1[/tex]

To get the least score, each of the 3 members must have 1 point each.

So:

[tex]Total = 3 * 1[/tex]

[tex]Total = 3[/tex]

Answer:

50 ml = 0.050 liters

Step-by-step explanation:

The solution is:

The mass/volume percent = 16/50 x 100% = 32%

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

Explanation

Given:

Mass of NaCl, m = 16.0 g

Volume of solution, v = 50.0 mL

What to find:

The mass/volume percent.

Solution

The mass/volume percent of the solution can be calculated using the formula below

The mass/volume percent  = mass/volume x 100%

so, we get,

The mass/volume percent

= 16/50 x 100%

= 32%

Hence, The mass/volume percent is 32%.

Answer:

The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Step-by-step explanation:

The form of the equation that passes through two points (x1, y1) and (x2, y2) is y = m x + b, where

Let us solve the question:

∵ The line passes through the points (-3, -2) and (3, 6)

∴ x1 = -3 and x2 = 3

∴ y1 = -2 and y2 = 6

→ Use the rule of m to find it

∵ [tex]m=\frac{6-(-2)}{3-(-3)}=\frac{6+2}{3+3}=\frac{8}{6}[/tex]

→ Simplify it by dividing up and down by 2

∴ m = [tex]\frac{4}{3}[/tex]

→ Substitute its value in the form of the equation above

∴ y = [tex]\frac{4}{3}[/tex] x + b

→ To find b substitute x and y by x1 and y1

∴ -2 = [tex]\frac{4}{3}[/tex] (-3) + b

∴ -2 = -4 + b

→ Add 4 to both sides

∴ -2 + 4 = -4 + 4 + b

∴ 2 = b

→ Substitute it in the form of the equation

∴ y = [tex]\frac{4}{3}[/tex] x + 2

∴ The equation of the line is y = [tex]\frac{4}{3}[/tex] x + 2

Answer:

<5 = 105 degrees

Step-by-step explanation:

From the description given, since line l is parallel to m then <4 is alternate to <5 and two alternate angles are equal, if thst is the case

<4 = <5 (alternate angle)

Since <4 = 105 degrees, hence m<5 = 105 degrees

Answer:

No solution

Step-by-step explanation:

if you replace the y with -2x-6 into the first equation, you will get rid of the x's which it gives you the hint that there is no solution.

Answer:

It can be solved in many forms

one by replacing each point to see which one satisfy the equation or by using quadratic formula

Answer:

x = 47°

Step-by-step explanation:

This is an exterior angle property, one of the properties in a triangle. The exterior angle theorem states that if a triangle's side gets an extension, then the resultant exterior angle would be equal to the sum of the two opposite interior angles of the triangle.

Answer:

x=45.6

Step-by-step explanation:

(2x-2)+x+45=180

Combine like terms.

3x+43=180

Subtract 43 on both sides.

3x+43=180

   -43 -43

3x=137

Divide by 3 on both sides.

3x=137

/3   /3

x=45.6

Answer:

The degree of the given polynomial is 5

Step-by-step explanation:

The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.

The degree of a monomial is the sum of the exponents of the variables that appear in it.

We have the following polynomial:

[tex]3x^2y + 4xy + 1 - 5x^4y - 6y[/tex]

Degree of the first monomial: 2+1=3

Degree of the next monomial: 1+1=2

Degree of the next monomial: 0

Degree of the next monomial: 4+1=5

Degree of the next monomial: 1

Thus, the degree of the given polynomial is 5

Answer:

101  

Step-by-step explanation:

100- (-1) NEGATIVE MINUS NEGATIVE CANCEL OUT ON EACH OTHER AND GIVE POSITIVE: 100 + 1 = SO THE ANSWER IS  101^F

The difference between these two extreme temperatures is of

101° F.

We have the highest temperature recorded in the town of Westgate which is equal to 100°F. Last winter, the lowest temperature recorded was -1°F.

We have to find the difference between these two extremes.

Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.

According to question, we have -

Highest temperature recorded = 100°F

Lowest temperature recorded = -1°F

Let the the difference between these two extreme temperatures be x. Then -

x = Highest temperature recorded - Lowest temperature recorded

x = 100 - (- 1) = 101° F

Hence, the difference between these two extreme temperatures is of

101° F.
