Answer:
The answer is "7.62 cm ".
Step-by-step explanation:
Given:
[tex]Width = 6\ cm \\\\Depth = 4 \ cm\\\\Vertical \ height = 7 \ cm\\\\[/tex]
Dividing the prism's face into two halves:
As just a result, the vertical height becomes 7cm, as well as the width, becomes [tex]\frac{6\ cm}{2} = 3 \ cm[/tex]. If the 's' on both sides of the edge is equal:
[tex]s^2 = width^2 + height^2\\\\[/tex]
[tex]= \sqrt{(width^2 + height^2)}\\\\[/tex]
[tex]= \sqrt{(3^2 + 7^2)}\\\\= \sqrt{9 + 49}\\\\= \sqrt{58}\\\\= 7.62 \ cm[/tex]
George practises his guitar for 1 1/5 hours per day on school days. On Saturday he increases to 2 1/2 times his normal time. How many hours does he practice on Saturdays.
Answer: 231/10
Step-by-step explanation: 11/5 x 21/2
= (11 x 21) = 231
= 231/5 x 2
= 231/10
Answer:
3 hours
Step-by-step explanation
It would be easier to convert your fractions into decimals.
1/5 is the same as 2/10. Since the denominator was multiplied by 2 then the numerator must be multiplied by 2 also.
2/10 in decimal form is 0.2
He would practice 1.2 hours per day on school days
On Saturday his practice is 2 1/2 times longer than 1.2 hours.
Convert 1/2 into decimal form. 1/2 is the same as 0.5.
So 2 1/2 is the same as 2.5
If you multiply the original time (1.2 hours) by 2.5, you'll know how long he practices on Saturday.
1.2 x 2.5 = 3 hours.
1.2
x 2.5
-------
60
24
------------
300
since you have 1 decimal place in the top number and 1 decimal in the bottom number, you must move your decimal 2 places to the left on your answer. Instead of 300, your answer becomes 3.00

Q3). 0.4x + 0.3y = 1.7
0.7x - 0.2y = 0.8
Solve it by using substitution method.
[tex]▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ { \huge \mathfrak{Answer}}▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ ▪ [/tex]
The values of :
[tex]x = 2[/tex][tex]y = 3[/tex]The given equations are :
[tex]0.4x + 0.3y = 1.7[/tex][tex]0.7x - 0.2y = 0.8[/tex]now, let's multiply both the equations with 10 on both sides.
so, now our equations will be :
[tex]4x + 3y = 17[/tex][tex]7x - 2y = 8[/tex]from Equation second :
[tex]7x - 2y = 8[/tex][tex]2y = 7x - 8[/tex][tex]y = \dfrac{7x - 8}{2} [/tex]now, let's substitute the value of y from here into Equation first.
[tex]4x + 3y = 17[/tex][tex]4x +3 \bigg ( \dfrac{7x - 8}{2} \bigg) = 17[/tex][tex]4x + \dfrac{21x - 24}{2} = 17[/tex][tex] \dfrac{8x + 21x - 24}{2} = 17[/tex][tex] \dfrac{ 29x - 24 }{2} = 17[/tex][tex]29x - 24 = 34[/tex][tex]29x = 34 + 24[/tex][tex]29x = 58[/tex][tex]x = \dfrac{58}{29} [/tex][tex]x = 2[/tex]here, we got the value of x = 2, let's plug it in equation second to find value of y :
[tex]7x - 2y = 8[/tex][tex]7(2) - 2y = 8[/tex][tex]14 - 2y = 8[/tex][tex]2y = 14 - 8[/tex][tex]2y = 6[/tex][tex]y = \dfrac{6}{2} [/tex][tex]y = 3[/tex]And value of y = 3

addison and kelsey are running on a path modeled by x^2+y^2-10x-18y-378=0, where the distance is in meters. what is the maximum distance between the runners at any given time
The maximum distance between them is the diameter of the circle, which is of 44 units.
The equation of a circle of center [tex](x_0, y_0)[/tex] and radius r is given by:
[tex](x - x_0)^2 + (y - y_0)^2 = r^2[/tex]
The diameter is twice the radius, and is the maximum distance between two points on the same circle.
They are running on a circular path, modeled by:
[tex]x^2 + y^2 - 10x - 18y = 378[/tex]
Completing the squares, the equation is:
[tex](x - 5)^2 + (y - 9)^2 = 378 + 5^2 + 9^2[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 378 + 25 + 81[/tex]
[tex](x - 5)^2 + (y - 9)^2 = 484[/tex]
Then, the radius is: [tex]\sqrt{484} = 22[/tex], which means that the maximum distance between the runners at any given time is of 44 units.

A=D+qm, solve for q.........
Step-by-step explanation:
A=D+qm
qm = A - D
q =(A-D) /m
Answer:
q = (A - D)/m
Step-by-step explanation:
A = D + qm
A - D = qm
(A - D)/m = q
So, the solve for q is q = (A - D)/m

Properties of coordinate planesDomain is the set of x-values that can be inputted into function f(x) Range is the set of y-values that are outputted by function f(x)Interval Notation/Inequality NotationStep-by-step explanation:
According to the graph, we see that our x-value stretches from x = -2 to infinity. Since x = -2 is a closed dot, it is included in the domain:
[-2, ∞) or -2 ≤ x < ∞
According to the graph, we see that our y-value stretches from y = -4 to infinity. Since y = -4 is a closed dot, it is included in the range:
[-4, ∞) or -4 ≤ y < ∞

Show that if 3x – 7 = 5, then x = 4.
Here, our given statement is 3x – 7 = 5, and we're asked to prove x = 4.
x=4
Statements Reasons
1. 3x – 7 = 5 Given
2. 3x – 7 + 7 = 5 + 7 Addition of 7 to equation (1)
3. 3x + 0 = 5 + 7 Substitution of –7 + 7 = 0 into (2)
4. 3x = 5 + 7 Substitution of 3x + 0 = 3x into (3)
5. 3x = 12 Substitution of 5 + 7 = 12 into (4)
6. 3x⁄3 = 12⁄3 Dividing equation (5) by 3
7. x = 12⁄3 Substitution of 3x⁄3 = x into (6)
8. x = 4 Substitution of 12⁄3 = 4 into (7)

Trey rented a truck for one day. There was a base fee of $17.95, and there was an additional charge of 96 cents for each mile driven. Trey had to pay $246.43
when he returned the truck. For how many miles did he drive the truck?
miles
Answer:
238 miles
Step-by-step explanation:
Subtract total cost with truck fee cost which makes it 228.48 then divide by the cost of each mile driven which is 96 cents, so it would be 238 miles

Prove the following relations: 1) (1 - cos²A) (1 + tan²A) = tan²A
Step-by-step explanation:
(1 - cos²A)(1 + tan²A) = tan²A
1 + tan²A - cos²A - cos²A · tan²A = tan²A
1 + tan²A(1 - cos²A) - cos²A = tan²A
1 - cos²A + tan²A(sin²A) = tan²A
sin²A + tan²A(sin²A) = tan²A
sin²A (1 + tan²A) = tan²A
sin²A (sec²A) = tan²A
sin²A (1/cos²A) = tan²A
(sin²A)/(cos²A) = tan²A
tan²A = tan²A → Proved

Which graph represents the solution to the inequality? 4v - 2 < 10
Answer:
Option C.
Step-by-step explanation:
First, simplify the inequality. Add 2 to both sides:
4v - 2 < 10
4v - 2 + 2 < 10 + 2
4x < 12
Divide both sides by 4:
4x ÷ 4 < 12 ÷ 4
x < 3
As 3 will not satisfy the inequality, it is not a solution. The option that shows x being less than 3 but not including is option C.
