Answer:
55 mph
Step-by-step explanation:
Given that:
Total miles of journey = 350 miles
Miles already driven = 75 miles
To cover the rest of the journey in 5 hours, the average speed of travel. Will be:
Recall:
Speed = (Distance left to cover ÷ budgeted travel time)
Distance left to cover : (total miles - distance already driven)
Average speed required = (350 - 75) / 5
= 275 / 5
= 55 mph

Answer:
A. [tex] x \leq -16[/tex]
B. b > 11
C. [tex] c \leq -13 [/tex]
D. [tex] x \geq -9[/tex]
Step-by-step explanation:
Given the following algebraic expression;
A. [tex] \frac {3x}{4} \leq 12 [/tex]
We would simplify the equation by multiplying all through by 4;
[tex] 4 * \frac {-3x}{4} \leq 12 * 4[/tex]
[tex] -3x \leq 48[/tex]
Divide both sides by -3;
[tex] x \leq -16[/tex]
B. 5b - 28 > 27
Rearranging the equation, we have;
5b > 27 + 28
5b > 55
Divide both sides by 5
b > 11
C. [tex] 13c \leq -169[/tex]
Divide both sides by 13
[tex] c \leq -13 [/tex]
D. [tex] 3x - 7 \geq 4x + 2[/tex]
Collecting like terms, we have;
[tex] 3x - 4x \geq 2 + 7[/tex]
[tex] -x \geq 9[/tex]
Divide both sides by -1
[tex] x \geq -9[/tex]
Change the word sentence into a mathematical equation. Tell what each variable represents.
1. A music club membership costs $17.00 and $7.00 per CD.
2. The total cost of a carpet is $3.00 times the number of square feet.
3. The amount of money you earn for allowance is $20 times the number of months.
4. The cost of belonging to a fitness club is $200 to join and $30 a month in membership dues.
Answer:
1. $17 + $7C.
This equation provides the total cost if you want to purchase a music CD along with a music club membership. C represents the amount of CDs you wish to purchase, and since each CD costs $7, the amount of money you would need to purchase C amount of CDs is $7C.
2. $3A.
This equation provides the total cost of the area of carpet you want to purchase. A represents the area of the carpet that you want to purchase, measured in square feet as provided by the question, and since each square foot costs $3, the total cost is $3A.
3. $20M.
This equation provides the total money you earn for allowance after M months. M is the number of months that have passed, and since you earn $20 for allowance every month, the total allowance you have earned is $20M.
4. $200 + $30M.
This equation provides the total cost for joining and staying in a fitness club for M months. The initial cost, $200, is applied no matter how many months you join, so we add it from the start; since each month, M, you have to pay $30, the total amount of membership dues is $30M.

In order for this problem to have more than one solution, one will have to make it such that the two sides are equal. Call the unknown quantity "x", and solve this equation like a literal equation;
5u + 3(4u - 6) = -3u - 27 + 20u + x
Simplify, (distribute and combine like terms);

Evaluate-8÷2+12×9-4×6
Answer:
Step-by-step explanation:
Use PEDMAS {Parenthesis ; Exponent ; Division ; Multiplication ; Addition; Subtraction }
8÷2 + 12*9 - 4*6 = 4 + 12*9 - 4*6 {Division}
= 4 + 108 - 24 {Multiplication}
= 112 - 24 {Additon}
= 88
Answer: 88
Step-by-step explanation:
Evaluate using PEMDAS.
P = Parenthesis; There are no parenthesis in this expression
E = Exponents; There are no exponents in this expression
M = Multiplication; 12 x 9 = 108, 4 x 6 = 24
D = Division; 8/2 = 4
A = Addition; 4 + (12 x 9) = 112
S = Subtraction; (4 + (12 x 9)) - (4 x 6)
112 - 24 = 88
A farmer is selling apples from his orchard. He uses the equation c = 1.6pto calculate the total cost, c, for every pound of apples, p.
a.) How much does a customer pay for 1 pound of apples?
b.) How much would 8.5 pounds of apples cost?
c.) A customer spent $5.20. How many pounds of apples did they purchase?
Answer:
A) $1.60
B) $13.60
C) 3 1/4 lb
Step-by-step explanation:
What we know:
A farmer uses the equation c = 1.6p to calculate the total cost, c, for p pounds of apples.
A) 1 pound would cost $1.60, as that is the unit rate.
B) 8.5 * 1.6
8.5 + (0.6 * 8.5)
8.5 + 5.1 = $13.60 for 8 1/2 lbs of apples.
C) 5.2/1.6
52/16
13/4 = 3 1/4 lbs of apple for $5.20

A. Explain why ABC and ADBE
are similar
B. What is the height of the building?
Step-by-step explanation:
This figure is not the best, but I'll try my best here
Since BC is parallel to BE (BC is part of BE) and BA is part of BD, two sides are parallel, making two angles congruent and the triangles therefore similar.
Since BA correlates to BD (they are parallel), we can use the knowledge that BA is 7 and BD is 42 to find the scaling factor to be 42/7 =6 from ABC to DBE. Since BC correlates to BE, BC = 10, and the scaling factor is 6, BC*6=BE= 60 = height

Answer:
Step-by-step explanation:
this is a 30 60 90 triangle.. b/c 2 of the angles are given and you know the total is 180 around a triangle so the last angle is 30
also you know the hypotenuse of this triangle is 10 so use cos and sin to figure out the other sides
Use SOH CAH TOA to remember how the sin and cos functions fit on the triangle
CAH = Cos(Ф) = Adj/ Hyp we are given the Ф angle and we know the hypotenuse so solve for the Adj side
Hyp*Cos(Ф)= Adj
10 * Cos(60) = Adj
5 = Adj = y
Use Sin for the other side and the mnemonic to remember how it fits on the triangle and solve for the Opposite , since we don't know that .. yet
Sin(Ф) = Opp/ Hyp
Hyp * Sin (Ф) = Opp
10 * Sin(60) = Opp
10 *[tex]\sqrt{3}[/tex]/2 = Opp
5*[tex]\sqrt{3}[/tex] = Opp = x
:) I know Sin(60) = [tex]\sqrt{3}[/tex]/2 from a table and also my memory .. know that one from memory

The required solution of the quadratic equation (4y - 3)² = 72 is y = 3 ± 6√2/4. Option A is correct.
What is simplification?
Simplification involves applying rules of arithmetic and algebra to remove unnecessary terms, factors, or operations from an expression.
Here,
Given expression, (4y - 3)² = 72
Simplifying the above expression:
(4y - 3)² = 72
4y - 3 = ±√72
4y - 3 = ±6√2
y = 3 ± 6√2/4
Thus, the required solution of the quadratic equation (4y - 3)² = 72 is y = 3 ± 6√2/4. Option A is correct.

Oliver read for 450450450 minutes this month. His goal is to read for 10\, percent more minutes next month. If Oliver meets his goal, how many minutes will he read in all during the two months
Step-by-step explanation:
450450450=100%
? =110%
110×450450450/100
495495495 mins=2nd month
add

945945945 minutes
There are 945 minutes will he read in all during the two months.
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Oliver read for 450 minutes this month.
And, His goal is to read for 10% more minutes next month.
Now,
Since, His goal is to read for 10% more minutes next month.
Hence, The extra minutes for next month = 10% of 450 minutes
= 10/100 × 450
= 45 minutes
Thus, The total minutes to read in all during the two months is,
⇒ 450 + (450 + 45) minutes
⇒ 450 + 495 minutes

Given
Variation: Direct Proportion
[tex]3.2m = \$38[/tex]
Required
Determine the cost of 2.4m length
Represent the cost of 2.4m length with x
So, we have:
[tex]3.2m = \$38[/tex]
and
[tex]2.4m = x[/tex]
Cross Multiply:
[tex]3.2m * x = \$38 * 2.4m[/tex]
[tex]3.2 * x = \$38 * 2.4[/tex]
Solve for x
[tex]x = \frac{\$38 * 2.4}{3.2}[/tex]
[tex]x = \frac{\$91.2}{3.2}[/tex]
[tex]x = \$28.5[/tex]
Hence, the cost of 2.4m length is $28.5
