Answer:
[tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]
Step-by-step explanation:
Average speed = distance/time
Average speed = [tex]\frac{9.6}{30} \frac{km}{min}[/tex] ; multiply by 60min/1hour
Average speed = [tex]\frac{95}{5} \frac{km}{hour}= 19.2 km/hour[/tex]
7x-3y = 8
3x-4y = 1
solving this by using eliminination method.
Lucazz please solve this
Given pair of linear equations in two variables are :
7x-3y = 8------------(1)
3x-4y = 1-------------(2)
On multiplying (1) with 3 then
21x-9y = 24 ---------(3)
On multiplying with 7 then
21x-28y = 7 ----------(4)
On subtracting (4) from (3) then
21x-9y = 24
21x-28y = 7
(-) (+) (-)
__________
0+19y = 17
__________
→ 19y = 17
→ y = 17/19
On substituting the value of y in (2) then
→ 3x-4(17/19) = 1
→ 3x -(68/19) = 1
→ (57x-68)/19 = 1
→ 57x-68 = 1×19
→ 57x -68 = 19
→ 57x = 19+68
→ 57x = 87
→ x = 87/57
Therefore, the value of x and y is 87/57 and 17/19 respectively.

Find the area of triangle PQR.
Answer:
70°
Step-by-step explanation:
Since PTS shape is equal to QTR
and PTQ shape is equal to STR
and Since QTP = 10
and Since PTS = 60
Add both up 70
Therefore PQR = 70°
Erika is going to the store to buy a gallon of milk and some apples. The gallon of milk costs $3.50 and apples
cost $1.50 per pound. Use this information to complete the table, create a graph, and write an equation that
represents Erika’s total cost, C, of buying the milk and a pounds of apples.
Answer:
C = $5.00
Step-by-step explanation:
C = $5.00 because IF Erika gets 1 pound of apples they would cost $5.00
$3.50

If Maria designs a function to predict the amount of revenue, r, generated as a function of the number of people, n, who attend a fundraiser, explain why 13.5 would not be a member of this function's domain?
Answer:
Only whole numbers of people, n, are assumed in the calculation.
Step-by-step explanation:
The function relating the number of people, n, to the revenue, r, implicity assumes that only whole people will purchase tickets. 13.5 would mean that 13 normal people and 1/2 of a person bought tickets. This can't be in the domain, since the ticket saleperson would run away if 1/2 of a person showed up: thus no ticket sale.
Actually, it may depend on how one defines a person. Is it 1/2 physically, or 1/2 mentally? I've personally seen the latter show up at some fundraisers.

Answer:
The real-world scenario is given as: A yacht traveling 20 miles due east off a harbor is located 50 miles due north from the yacht
Recall:
Pythagorean Theorem applies to a right triangle where and c is the hypotenuse.
If we know the two of the three side lengths of a right triangle, we can find the other third length.
An example of a scenario where the Pythagorean Theorem can be applied to solve a real-world problem can be sketch in a diagram
Therefore:
The real-world scenario is given as: A yacht traveling 20 miles due east off a harbor is located 50 miles due north from the yacht

Answer: Read the Explanation
Step-by-step explanation:
m<7 = 120
m<5 = 120
m<6 = 60
m<2 = 60
The reason why they are 60 is because they are supplementary angles to complete a straight line so like since 3 = 120 4 = 60 since its a straight line.

correct answer needed full explanation
Answer:
-3×4= -12
-2×4= -8
three rational number between them are -11 , -10 , -9
Step-by-step explanation:
hope that it will help you
The rational numbers between -3 and -2 are;
-5/2, -9/4 and -11/4
Rational NumbersRational numbers are numbers that can be represented as the quotient of two integers but not equal to zero.
Now, to find the rational number between -3 and -2, we will use the formula;
x = ½(a + c)
x = ½(-3 + (-2))
x = -5/2
Another rational number is;
x = ½(-(5/2) + (-2))
x = ½(-9/2)
x = -9/4
Using the same pattern, we can still get another one as -11/4
In conclusion, the three rational numbers will be -5/2, -9/4 and -11/4

Jane lives on a straight road that goes east and west. She starts from a point 6.3 miles west of her home and drives a certain distance to the store. The store is more than 4 1/2 miles east of her home.
Let d represent the distance Jane drove. Which inequality represents this situation?
−6.3+d≥−4 1/2
−6.3+d>4 1/2
−6.3+d>−4 1/2
−6.3+d≥4 1/2
The inequality that represents the situation is as follows (where d
represents the distance Jane drove):
−6.3 + d > 4 1/2
She lives on a straight road that goes east and west.
d = distance Jane drove.
She started from a point 6.3 miles west of her home and drives a certain distance to the store. Therefore,

Estella signed a one-year lease. She pays $720 per month in rent. If she wants to move out three months early, how much money will she owe when she moves out? I assume $2,160 ??
Answer:
$2160
Step-by-step explanation:
Since she moved out 3 months early, you would do 720x3, since she pays $720 every month. 3x720 = $2160
2) Find the area and perimeter of a semi -circular disc whose radius is 10cm. (take π = 3.14)
Answer:
Area =Pi r2=3.14×10x10
=3.14×100cm2
=3.14cm2
Perimeter = 2 pi r
=2 ×3.14×10
=6.28cm
Or =Pi d
= 3.14 ×20cm
=62.8cm
Note:R means radius
D means diameter
radius is half of a diameter e.g radius is10 and diameter is 20

Answer:
y = 12
x = 4.4
Step-by-step explanation:
Scale factor is calculated by comparing the opposing side lengths and writing them as a fraction:
8/20 = 2/5 is the scale factor now to find the value of x and y we can use this scale
y/30 = 2/5 cross multiply expressions
5y = 60 divide both sides by 5
y = 12
same goes for x:
x/11 = 2/5 cross multiply
5x = 22 divide both sides by 5
x = 4.4
Simplify the expression.
Step-by-step explanation:
since all base numbers have the same exponent, we can combine the base numbers first and then apply the exponent :
(12×45×50)^(1/3) = 27000^(1/3)
and remember what a 1/... exponent means : it means the root of the ... degree.
so, here we need a cubic root or a root of the third degree
