Yes, Briggs will have enough to complete a job requiring 1900 bricks. Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.

Given that On the basis of past experience, a contractor expects to find 4.5% Broken Brickson every truckload.

He orders 2000.

We need to see whether Briggs will have enough to complete a job requiring 1900 bricks.

Example:

- 20% of M

= 20/100 x M

= 1/5 x M

- 25% of M

= 25/100 x M

= 1/4 x M

Find 4.5% of 2000.

= 4.5% x 2000

= 4.5 / 100 x 2000

= 4.5 x 20

= 45 x 2

= 90

The remaining bricks are:

= 2000 - 90

=  1910

We see that Briggs will have enough to complete a job requiring 1900 bricks.

1910 > 1900.

Thus, Briggs will have enough to complete a job requiring 1900 bricks.

Since he has 1910 bricks remaining and he needs only 1900 bricks to complete the work.

If you invest a 100% in stocks however, you stand to make an average of 9.2% but a chance of a worst return of -40.40%.

In the given statement is:

Your friend tells you he is going to start investing and would like to earn a 10% return. He says stocks make him nervous, so he will only be investing 10% in stocks and the remaining 90% will be invested in bonds.

Based on the graph given on bond and stock returns, the average return if one invested 100% in bonds or in stocks is 5.0% and 9.2% respectively.

What happens if you invest 100% in either stocks or bonds?

The graph shows that when you invest a 100% in bonds, the average return you stand to make it 5.0% while the worst return is -2.1%.

Answer:

b) 8 × 12 + 8 × 30

Step-by-step explanation:

Now we have to,

→ Find the equivalent expression.

The property we use,

→ Distributive property.

The expression is,

→ 8(12 + 30)

Let's simplify the expression,

→ 8(12 + 30)

→ 8(12) + 8(30)

→ (8 × 12) + (8 × 30)

→ 96 + 240

→ 336

Hence, the option (b) is correct.

The values of m and b are 6 and 2 respectively and the value of m + b is 8.

It is given that the equation y = mx + b   ....(1) for the line parallel to the graph of  y = 6x + -2    ...(2) means that slope of the equation y = mx + b which is parallel to the graph y = 6x + -2  is same i. e on comparing equation (1) and (2) , we get m = 6

On the other hand , the equation y = mx + b has the same y- intercept as the graph of y = 36x + 2   .....(3)

On  comparing equation (1) and (3) , we get b = 2

Therefore , m + b = 6 + 2

In 15 years, the account will be worth $1896 if the 3.7% interest is compounded monthly on initial deposit of $1100.

It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.

Given Data

A =  [tex]P(1+\frac{r}{100} )^{t}[/tex]

P=$1100

r =3.7%

t = 15years

Substitute the values in formula, A = [tex]P(1+\frac{r}{100} )^{t}[/tex]

A= 1100(1+{3.7/100})¹⁵

A = 1100(1+0.037)¹⁵

A = 1100(1.037)¹⁵

A= 1100(1.724)

A= 1896.4

Explanation below.

Step-by-step explanation:

1. To estimate, firat round the two numbers, 608 and 6.

When rounding if the numbers are 1,2,3,4 round down and if the numbers are 5,6,7,8,9 round up. But in this case we are just estimating an answer so we can just round 6 to 5 and 608 to 600. However, if the directions say to round to a specific place value, then follow the directions.

608 rounded to 600

6 rounded to 5

2. Multiply.

600 × 5 = 3,000

3. Solve with exact given numbers.

The probability that the numbers on the two chips will differ by more than 2 will be ( 1 / 2 ).

Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.

Probability = Number of favorable outcomes / Number of sample

Given that an urn contains twenty chips, numbered 1 through 20. Two are drawn simultaneously.

Number of favorable outcomes = ( 4 - 2 ) , ( 3 - 1 ) , ( 6 - 4 ) , ( 10 - 8 ), ( 11 - 9 ), ( 7 - 5 ), ( 14 - 12), ( 15- 13 ) , ( 18 - 16 ), ( 19 - 17 ) = 10

Number of samples = 20

Probability = Number of favorable outcomes / Number of sample

Probability = 10 / 20

Probability = 1 / 2

Therefore, the probability that the numbers on the two chips will differ by more than 2 will be ( 1 / 2 ).

Step-by-step explanation:  2+7=9 and 2-7=-5

Answer: y=2x-14

Step-by-step explanation:

Solve for x

x/2+7 = y

x/2+7-7=y-7

x/2=y-7

2x/2=2(y-7)

x=2y-14

y=2x-14  ==> switch the x and y variables

(a). The equation of the line L in the form of y = mx + b is y + 2x  = 0.

(b). The equation of the line K that passes through the point (0, -1) and is perpendicular to the line L is y = 2x - 1.

(c). The intersection of the lines and K is located at a location with the coordinates (0,-1).

The equation of a line has the usual form axe + by + c = 0. Here, x and y are the variables, a and b are the coefficients, and c is the constant term. You may also find and see the equation of a line in the slope-intercept form, point-slope form, two-point form, intercept form, and normal form.

The formula of slope is given by m = (y₂-y₁)/(x₂-x₁).

Here, m is the slope of the line.

(x₁, y₁) and (x₂, y₂) are the two points of the line.

Now put the value of x₁, y₁, x₂, y₂  in

m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]

m = [tex]\frac{3-1}{-1-1}[/tex]

m = 2/-1

m = -2  

The slope of the line perpendicular is:

mₐ = - 1/m

mₐ = -1/-2

mₐ = 2

(a) The equation (in the form y = mx + b) of the line L.

(y-y₁) = m(x-x₁)

(y-1) = -2(x-1)

y-1 = -2x-1

y = -2x

y + 2x  = 0        

(b) The equation of the line K that passes through the (0, -1) and is perpendicular to the line L.

x = 0 and y = -1

y = mx + b  

y = 2x + b  

-1 = 2×0 + b  

-1 = b

b = -1

Substituting the above in y = mx + b to get:

y = mx + b

y =2x + (-1)

y = 2x - 1

(c) The coordinates of the point at which the lines and K intersect.

y = 2x - 1

y+2x+1=0

(2x-1)+2x+1=0

4x =0    

x = 0, y = -1

The intersection of the lines and K is located at a location with the coordinates (0,-1).

The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.

We need to find the vertices of the given ellipse.

The major axis of the ellipse cuts the ellipse into two distinct points called the vertices of the ellipse. The line perpendicular to the major axis of the ellipse is the minor axis, and it cuts the ellipse at two distinct points called the covertices of the ellipse. The midpoint of the vertices of the ellipse, or the covertices of an ellipse is the centre of the ellipse. The endpoints of the major axis are the vertices, and the endpoints of the minor axis are the covertices.

Equation of the ellipse = x²/a² + y²/b² = 1

Vertices of Ellipse: (a, 0), (-a, 0)

As we know, the endpoints of the major axis are the vertices.

From the given figure we can see that axis of the ellipse passes through the points (-1, 2) and (-9, 2).

The vertices of the given ellipse are (-9, 2) and (-1, 2). Therefore, option D is the correct answer.

Initial fee = $10

Let the constant fee for each hour of work = M

Fee for 5 hours of work = $35

Every mowing job for 5 hours = Initial fee + constant fee for 5 hours
$35 = $10 + M x 5

35 = 10 + 5M

25 = 5M

M = 5
