1) Mr. Isaac invested $7200 at 8% simple interest per annum.
Calculate:
a) The interest earned after 7 years.
b) The TOTAL amount of money in his account after 7 years,
Answer:
Mr. Isaac should have gained $4,032 in interest, and the total amount of money he earned should be $11,232.
Step-by-step explanation:
0.08 * 7 = 0.56
0.56 * 7200 = 4,032
4,032 + 7200 = 11,232
Given the measure of angle 8 is 130o. What is the value of x if the measure of angle 5 is (x - 40)?
Number only (no words or variables)
Answer:
90Step-by-step explanation:
Angle 5 forms a linear pair with angle 8:
m∠5 + m∠8 = 180°Substitute the values and solve for x:
x - 40 + 130 = 180x + 90 = 180x = 90Answer:
The value of x is 90°.Step-by-step explanation:
We know that:
∠8 = 130°∠5 = x - 40∠5 + ∠8 = 180Work:
130 + (x - 40) = 180Opening the brackets:
130 + x - 40 = 180Solving:
90 + x = 180=> x = 180 - 90=> x = 90°Hence, the value of x is 90°.

2. Find the slope of a line that passes through (-2, -3) and (1, 1). (1 point)
Answer:4/3
Step-by-step explanation:
Use the slope formula
m = [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{1-(-3)}{1-(-2)} = 4/3[/tex]
Answer:
The slope of a line that passes through (-2, -3) and (1, 1) is 4/3.
Step-by-step explanation:
Here's the required formula to find slope line :
[tex]\star{\underline{\boxed{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}}}[/tex]
Here, we have provided :
[tex]\begin{gathered} \footnotesize\rm {\underline{\underline{Where}}}\begin{cases}& \sf y_2 = 1\\& \sf y_1 = - 3\\ & \sf x_2 = 1\\ & \sf x_1 = - 2\end{cases} \end{gathered}[/tex]
Substituting the values in the formula to find slope line :
[tex] \begin{gathered} \qquad{\longrightarrow{\sf{m = \dfrac{y_2 - y_1}{x_2 - x_1}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{(1) - ( - 3)}{1 - ( - 2)}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{1 + 3}{1 + 2}}}} \\ \\ \qquad{\longrightarrow{\sf{m = \dfrac{4}{3}}}} \\ \\ \qquad{\star{\underline{\boxed{\frak{m = \dfrac{4}{3}}}}}} \end{gathered}[/tex]
Hence, the slope line is 4/3.

Help ASAP please please
Answer:
250cm³
Step-by-step explanation:
The formula for volume is given:
[tex]V=\frac{\pi r^2h}{3}[/tex]
The diameter is also given: 10cm. To find the radius, divide the diameter by 2:
[tex]r=\frac{d}{2}\\r=\frac{10}{2}=5[/tex]
Now, plug that in all the known variables and solve for the volume:
[tex]\rightarrow V=\frac{(3)(5)^2(10)}{3}\\\rightarrow V=\frac{(3)(25)(10)}{3}\\\rightarrow V=\frac{750}{3}\\\rightarrow V=250[/tex]
The volume of the cone is 250cm³

You have 20 bucks in your pocket.
You got a paycheck this morning from part-time work: $50.00
You bought a magazine in the store next to school at lunch: $6.95
You bought breakfast at McDonalds: $9.95
You take a friend to the show. It's the 8 p.m. show: $20
A friend pays you back $15.00 in the afternoon.
You buy two juices from the machine in the cafeteria at lunch: $4
Answer:
the answer would be $45.55
<3
Step-by-step explanation:
20$ + $50.00 = $70
$70 - $6.95 = $64.5
$64.5 - $9.95 = $54.55
$54.55 - $20 = $34.55
$34.55 + $15 = $49.55
$49.55 - $4 = $45.55

7. What is the 24th term of the geometric sequence that begins 10, 11, 12.1
Answer:
89.5430243255237372246531
Step-by-step explanation:
The first term is a1=10. The common ratio is r=11/10 = 1.1. The n-th term is ...
an = a1·r^(n-1)
so the 24th term is ...
a24 = 10·1.1^(24-1) = 10·1.1^23
a24 = 89.5430243255237372246531

|2X-3|-7=0
Answer:
{ x : x = -2 U x = 5 }
Step-by-step explanation:
| 2x - 3 | - 7 = 0
Add 7 to both sides: | 2x - 3 | = 7
So either 2x - 3 = 7
2x = 10
x = 5
Or -(2x - 3) = 7
-2x + 3 = 7
-2x = 4
x = -2
{ x : x = -2 U x = 5 }

A(n)=2+ (n-1)(7)
Answer:
a(2) = 9
a(4) = 23
a(10) = 65
Step-by-step explanation:
a(2) = 2 + (2 - 1)(7)
= 2 + 1(7)
= 2 + 7
= 9
a(4) = 2 + (4 - 1)(7)
= 2 + 3(7)
= 2 + 21
= 23
a(10) = 2 + (10 - 1)(7)
= 2 + 9(7)
= 2 + 63
= 65

A circular running track is 1/4 mile long. Jamie runs on this track, completing each lap in 1/20 of an hour. What is Jamie’s running speed? Make sure you include the unit of measure.
Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.
Step-by-step explanation:
A circular running track 1/4 is a mile long.
Elena runs on this track, completing each lap in 1/20 of an hour.
Speed formula is used to determine the speed of Elena. The formula of speed is given by:
----- (1)
where S is the speed, D is the distance and T is the time taken by Elena to run a circle.
Now, put the value of distance D and time T in the equation (1).
Speed = 5 miles/hour
Therefore, the running speed of Elena is 5 miles/hour.

Can someone help me on this?
Answer:
a) y -6 = -1.21068(x +2)
b) y -6 - 0.82598(x +2)
Step-by-step explanation:
The slope of a line is the tangent of the angle it makes with the +x axis.
We are given a point on lines j and k, so we can write the equation of the line if we know its slope. The slope of line m can be found from the two given points on that line:
slope = (y2 -y1)/(x2 -x1)
= (2 -(-1))/(5 -(-3)) = 3/8
a)The angle that line k makes with the x-axis is 109° more than the angle made by line m. The slope of line k can be found using the formula for the tangent of the sum of angles:
tan(α+β) = (tan(α)+tan(β))/(1 -tan(α)tan(β))
For tan(α) = 3/8, and β = 109°, this becomes ...
slope of line k = (3/8 +tan(109°))/(1 -3/8·tan(109°))
= (3 +8tan(109°))/(8-3tan(109°)) ≈ -1.21068
__
The point-slope formula for a line is ...
y -k = m(x -h) . . . . . . line with slope m through point (h, k)
Point (-2, 6) is given as being on lines k and j, so the equation of line k can be written ...
y -6 = -1.21068(x +2) . . . . equation of line k
__
b)Line j is perpendicular to line k, so its slope will be the opposite reciprocal:
slope line j = -1/(-1.21068) ≈ 0.82598
Then the point-slope equation of line j is ...
y -6 = 0.82598(x +2) . . . . equation of line j
_____
Additional comment
The figure shown is impossible. The attachment shows line m through the two given points, and line k making an angle of 109° with it, as calculated above. The angle between lines k and n at the point of intersection with the y-axis cannot be 71° as shown in the given diagram. It is closer to 70°.
__
The given angles (109°, 71°) are supplementary, suggesting that lines m and n are intended to be parallel. In that case, the intersection point with of line n with the y-axis is (0, 3.5) and the line through that point and (2, 6) can have the equation 5x +4y = 14 (line k). Its perpendicular can have equation 4x -5y = -38 (line j). The angles made by these lines are about 108.1° and 71.9°, not the angles shown in the diagram.

Is 2 7/8- 1 7/9 greater than 1 or less than 1?
Answer:
Slightly greater than 1.
Step-by-step explanation:
Greater than 1
Convert each to fractions with common denominators

2 + 7/8 - 1 - 7/9
1 + 7/8 - 7/9
1 + 63/72 - 56/72
1 + 7/72
1 7/72 is slightly greater than 1.
