Answer:
25 bricks
Step-by-step explanation:
Calculate the volume of one brick:
Volume = (11')(8")(5") = 440 in^3
Divide the volume of a one brick into the volume of concrete that will be used:
(11000 in^3 concrete)/(440 in^3 concrete/brick) = 25 bricks

You had $30 yesterday. You spent 20% of it today. How much money do you have left?
ANSWER
$24
EXPLANATION
You had $30 yesterday and you spent 20% of it today.
Since you spent 20% of it, the percentage you will have left is:
100 - 20 = 80%
So, you have 80% of $30.
That is:
[tex]\frac{80}{100}\cdot\text{ 30 = \$24}[/tex]You have $24 left.
Either by striding 80cm or by striding 70cm Anne takes an exact number of steps to cross the road find the least width of the road in meters
Exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.
As given in the question,
Anne takes exact number of steps to cross the road either by striding 80cm or by striding 70cm.
Conversion of the units
1 meter = 100 centimeters
1 centimeter = 1/100 meter
80 cm = 80 /100
= 0.8 meters
70 cm = 70 /100
=0.7 meters
Least width of the road is calculated by finding least common multiple of 0.8 meters and 0.7 meters
0.8 = 8 × (1/10)
0.7 = 7 × (1/10)
least common multiple = 7 × 8 × (1/10)
= 5.6 meters
Therefore, exact number of steps taken by Anne to cross the road either by striding 80cm or by striding 70cm , then the least width of the road is equal to 5.6meters.

in the graph, the coordinate point (4,-9) is ____in the graph, the coordinate point (1,0) is ____in the graph, the coordinate point (7,0) is ____in the graph, the coordinate point (4,0) is ____the options: an x-intercept, a y-intercept, a vertex, on the line of symmetry
Answer:
In the graph, the coordinate point (4,-9) is a vertex
In the graph, the coordinate point (1,0) is an x-intercept
In the graph, the coordinate point (7,0) is an x-intercept
In the graph, the coordinate point (4,0) is on the line of symmetry.
Explanation:
The x-intercepts are the points where the parabola crosses the x-axis, so the coordinates of the x-intercepts are (1, 0) and (7, 0)
The y-intercept is the point where the parabola crosses the y-axis, so the y-intercept is (0, 7)
The vertex is the minimum point of the parabola, in this case, (4, -9).
The line of symmetry depends on the first coordinate of the vertex, so the line of symmetry is x = 4. It means that any point with a first coordinate equal to 4 is on the line of symmetry.
Then, the answers are:
In the graph, the coordinate point (4,-9) is a vertex
In the graph, the coordinate point (1,0) is an x-intercept
In the graph, the coordinate point (7,0) is an x-intercept
in the graph, the coordinate point (4,0) is on the line of symmetry.

The exponential function has the following form:

[tex]\begin{gathered} x=2\rightarrow y=171 \\ a=19 \\ \\ 171=19\cdot b^2 \\ \\ b^2=\frac{171}{19}=9 \\ \\ b=\sqrt[]{9}=3 \end{gathered}[/tex]So, the answer will be:

Based on the amount of the loan, and the number of periods as well as the APR, the total amount of the monthly payment would be $6,423.
How to find the total monthly payments?The monthly payments for the loan would be constant so they can be considered to be annuities.
The value of these annuities would be:
Present value of annuity = Annuity x ( 1 - (1 + rate)^-number of periods) / rate
6,100 = Annuity x (1 - (1 + 5%/12)⁻⁽²ˣ¹²⁾ / 0.05/12)
Annuity = 6,100 / 22.793898393955992921598741250451
= $267.62
The total monthly payment is:

Angel earned $70 mowing lawns, which is 140% of the amount George earned. How much money did George earn?
The total amount earned from mowing lawns by George is $50
How to determine the amount earned by George?From the question, we have the following parameters that can be used in our computation:
Earnings percentage = 140%
Angel total earnings in mowing lawns = $70
The amount earned from mowing lawns by George is then calculated as
Angel total earnings in mowing lawns = Earnings percentage x Total amount earned from mowing lawns by George
Substitute the known values in the above equation
So, we have
70 = 140% x Total amount earned from mowing lawns by George
Divide both sides by 140%
Total amount earned from mowing lawns by George = 50
Hence, the total amount is $50

What is meant by triangle?The triangle exists a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°.
A triangle is a 3-sided polygon that is occasionally (though not frequently) referred to as the trigon. There are three sides and three angles in every triangle, some of which may be the same.
Angles 1 and 2 are remote interior angles while angle 3 exists as a remote exterior angle. So there exists a property of a triangle in that the sum of the remote interior angles exists equivalent to the remote exterior angle.
∠1 +∠2 = ∠3.

Algebraically solve for x: 7/2x-2/x+1=1/4
Step-by-step explanation: Check the photo
Answer:
x = -2
Step-by-step explanation:
7/(2x) - 2/x + 1 = 1/4
7/(2x) - 4/(2x) + 1 = 1/4
(7-4)/(2x) = 1/4 - 1
3/(2x) = 1/4 - 4/4
3/(2x) = - 3/4
3 = (-3/4)(2x)
3 = -6x/4
3*4 = -6x
12 = -6x
12/-6 = x
-2 = x
Check:
7/(2*-2) - 2/-2 + 1 = 1/4
7/-4 + 1 + 1 = 1/4
-7/4 + 2 = 1/4

The cost of the jam Elmo uses to make the sandwiches =$1.65
What is the cost of the jam Elmo uses to make the sandwiches?
B globs of Peanut butter at 4 cents = 4B
J blobs of Jam at 5 cents = 5J
The number of sandwiches is given by the linear equation,
N(4B + 5J ) =$ 2.53
N(4B + 5J ) = 253 cents ---(1)
The factors of 253 = 1, 11, 23, 253.
Since N > 1 , N is 11 or 23
Considering N = 11
11(4B + 5J ) = 253
4B + 5J = 23 ---(2)
The possible values of B and J to satisfy the linear equation:
B = 2 and J = 3
Substituting B and J in (2)
4B + 5J = 23
4 (2) + 5(3) = 23
8 + 15 = 23
23 = 23

mary walked to school at an average speed of 2 miles per hour and jogged back along the same route at an average speed of 6 miles per hour. if her total traveling time was 1 hour, what was the total number of miles in the round trip?
As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile
How to calculate total distance?We can calculate the total distance traveled by a body with position function s (t) if it moves along a coordinate line without changing direction from t = a to t = b. If the body changes direction during the journey, we must integrate the body's speed |v (t)| to find the total distance traveled.
Therefore,
We know Mary spent only a third of the time coming from school as she did going because she traveled three times as fast coming from school as she did going to school (6 miles per hour versus 2 miles per hour). If x represents the time it took her to get to school, then x/3 represents the time it took her to return.
Knowing that the total trip took 1 hour, we have:
x + x/3 = 1
3x/3 + 1x/3 = 1
4x/3 = 1
x = 3/4
So we know it took Mary 3/4 of an hour to get to school (and 1/4 of an hour to get home).
Remembering that distance = rate × time, Mary's commute to school was (2 miles per hour) × (3/4 of an hour) = 3/2 mile. Furthermore, because she returned via the same route, she must have traveled 3/2 of a mile.
As a result, the total distance traveled by Mary in her round trip is 3/2 mile + 3/2 mile = 6/2 mile = 3 mile.

The probability that the score of a randomly selected examinee is less than 370 is 0.113
Mean of the gmat score = 410
Standard deviation of the deviation = 33
The randomly selected examinee be X ,
Thus X = 370
So , we need to find the probability that the score of a randomly selected examinee is less than 370 i.e.
P(X < 370)
Now , let us the z-score with normal distribution formula
Z = (X - μ) / σ
Z = (370 - 410) / 33
Z = -40 / 33
Z = -1.21
Thus P(X < 370) = P(Z < -1.21)
From the z - table , we can get that

The angle does a 3.8 meter ladder make with the ground if it reaches 2.1 meter up the wall is 33.54 degrees and the distance between the foot of the ladder and the wall is 3.16 meters
The length of the ladder = 3.8 meter
The length of wall = 2.1 meter
Draw the figure using the measurements
We have to use the trigonometric function
The angle that a ladder make with the ground
sin θ = Opposite side / Hypotenuse
sin θ = 2.1/3.8
θ = 33.54 degrees
The distance from the foot of the ladder from the wall
cos θ = Adjacent side / Hypotenuse
cos 33.54 = Adjacent side / 3.8
Adjacent side = 3.8 × cos 33.54
= 3.16 meters
