Eliana travels at an average speed of 50 mph for 60 miles. Without stopping, Eliana then travels 130 miles in 2.5 hours. Find her average speed for the entire journey to 2 dp.
Answer:
102 mph
Step-by-step explanation:
Eliana travels at an average speed of 50 mph for 60 miles.
Without stopping, Eliana then travels 130 miles in 2.5 hours.
We calculate the speed here
Speed = Distance in miles /Time in hours
Speed = 130 miles/2.5 hours
= 52 miles per hour
Hence, her average speed for the entire journey is calculated as:
50 mph + 52 mph
= 102 mph

Answer: 48 square units
=============================================================
Explanation:
Draw a vertical line to cut the triangle into two equal parts. You'll get two right triangles.
The horizontal leg of one of those smaller triangles is 12/2 = 6 units. The hypotenuse is 10 units. Through the pythagorean theorem, you should find the vertical leg is 8 units.
We have a 6-8-10 right triangle.
The area of this smaller triangle is base*height/2 = 6*8/2 = 48/2 = 24 square units.
So the area of the larger triangle is 2*24 = 48 square units.

Find q
(7q-46)
(3q+6)
Answer:
[tex]q = 22[/tex]
Step-by-step explanation:
The angle measure of a straight line is (180) degrees As given in the picture, line (AC) is a straight line, thus its angle measure is (180) degrees. Angles (ABD) and (DBC) make up line (AC). Therefore, one can conclude that the sum of angles (ABD) and (DBC) is (180) degrees. Form an equation, simplify and use inverse operations to solve for the unknown parameter (q).
[tex](<ABD) + (<DBC) = (AC)[/tex]
Substitute for the angle measures,
[tex](7q-46)+(3q+6)=180[/tex]
Simplify,
[tex]10q-40=180[/tex]
Inverse operations,
[tex]10q-40=180\\\\10q = 220\\\\q = 22[/tex]

A $20, 000 brand new car depreciate its value every year following the pattern, $16,000, $12,800, $10,240. How much will the car be after 5 years?
A.$10, 000
B.$8,192
C.$6553.6
D.$6000
Answer:
Step-by-step explanation:
Use the info given in the exponential equation to find the value of b, the rate of decay.
[tex]v(t)=a(b)^t[/tex] where v(t) is the value of the car after a certain number of years, t, have gone by, a is the initial value, and b is the rate of decay. We have everything we need but b:
a = 20000
v(t) = 16000 after t = 1 year:
[tex]16000=20000(b)^1[/tex] so
b = .8 Taken in context, this means that the car depreciates 20% each year. Now we can solve the problem being asked of us, which is to find the value of the car after t = 5 years:
[tex]v(t)=20000(.8)^5[/tex] which simplifies down a bit to
v(t) = 20000(.32768) so
v(t) = 6553.60, choice C.

The area ratio of two similar soilds is 169:289 if the volume of the smaller solid is 689,858 cm what is the volume of the larger solid
Answer: [tex]1,542,682\ cm^3[/tex]
Step-by-step explanation:
Given
The ratio of two similar figures is 169:289
Suppose, their length ratio is x:y
[tex]\therefore \dfrac{x^2}{y^2}=\dfrac{169}{289}\\\\\Rightarrow \dfrac{x}{y}=\dfrac{13}{17}[/tex]
Similarly, cube of the ratio is equal to the volume ratio
[tex]\Rightarrow \left(\dfrac{13}{17}\right)^3=\dfrac{689,858}{V}\\\\\Rightarrow V=689,858\times \dfrac{17^3}{13^3}\\\\\Rightarrow V=314\times 17^3\\\\\Rightarrow V=1,542,682\ cm^3[/tex]
Thus, the volume of the larger solid is [tex]1,542,682\ cm^3[/tex]

They bought $26 worth of snacks and a ticket for each family member.
What is the price of each ticket if all tickets are the same price
Answer:
8$
Step-by-step explanation:
since it was 26$ worth of snacks, first subtract 74 from 26
74-26= 48$ left
from this 48$, they bought tickets, therefore price for one ticket= 48/6=8$
therefore each ticket cost 8$

What additional information could be used to prove that the triangles are congruent using AAS? Select two options.
AngleC ≅ AngleQ
CB ≅ QM
AC = 3.9cm and RQ = 3.9cm
mAngleC = 35° and mAngleQ = 35°
AB = 2.5cm and MQ = 2.5cm
Answer:
Option 1: AC= 3.9cm and RQ=3.9cm
Option 2: CB = QM
Step-by-step explanation:
i think because you need a side
The additional information needed to prove both triangles are congruent by AAS is any of the following:
C. AC = 3.9cm and RQ = 3.9cm
E. BC = 2.5cm and MQ = 2.5cm
What is the AAS Theorem?Based on the AAS theorem, two triangles are proven to be congruent if two angles and one non-included side in one triangle are congruent to corresponding two angles and one non-included side in the other triangle.
From the image of the triangles, we know that two pairs of the angles, 29° and 116°, are congruent to each other in the two triangles.
For us to prove that both triangles area congruent by the AAS theorem, we will need to know either of the following: C. AC = 3.9cm and RQ = 3.9cm or E. BC = 2.5cm and MQ = 2.5cm.

Area of field = 10 cm²
Step-by-step explanation:
Given field is a trapezium;
Parallel sides of given field are; 1¹/₂ cm and 3¹/₂ cm
Height of trapezium = 4 cm
Find:
Area of field
Computation:
Area of field = Area of trapezium
Area of trapezium = [Sum of Parallel sides / 2][h]
Area of field = [(1¹/₂ + 3¹/₂) / 2][4]
Area of field = [(5) / 2][4]
Area of field = [2.5][4]

Answer:

Step-by-step explanation:
20 got 4 added to it and the only number that gives you 24 when you multiply it is 4x6 and we can prove that to be right because the one before it is 4x5 and it gives us 20. Now that we know the multiplier is 5 and 6 we can ask ourselves, "What do I multiply by 5 that gives me 60?" And that is 12. So 12x6 is 72 for x.

Answer:
y is 8/5 when x = -4.
Step-by-step explanation:
If the value of "Y" varies directly with "X", we can write y = kx, where k is the constant of proportionality.
If "y=-8,when x=20," then we can find k: -8 = 20k, or k = -2/5.
Then y = (-2/5)x.
If x = -4, then y = (-2/5)(-4) = 8/5
y is 8/5 when x = -4.

Joe Will need to pay a commission of [$7.50]. The Total amount Charged by the broker will be [$17.50]
Step-by-step explanation:
Joe will need to pay a commission of [tex]\$7.50[/tex] and Total amount charged by broker will be [tex]\$17.50[/tex].
What is commission ?Commission is a form of money pay as remuneration for services rendered or products sold.
A.We have,
Joe's current portfolio [tex]=\$ 50,000[/tex]
Price of one stock [tex]=\$15[/tex]
So,
As his portfolio is less than [tex]\$100,000[/tex], he have to pay [tex]15\%[/tex] and [tex]\$10[/tex] trade fee,
So,
Price of [tex]50[/tex] shares [tex]=50*15=\$750[/tex]
Commission charge [tex]=1\%\ of\ 750[/tex]
[tex]=\$7.5[/tex]
So, commission of [tex]\$7.5[/tex] will be paid.
B.So,
Total amount charged by Broker [tex]=10+7.5=\$17.5[/tex]

Answer:
A.) 20
Step-by-step explanation:
These angles are complementary meaning they add up to 90°.
4x - 10 + x = 90
5x - 10 = 90
5x = 100
x = 20
Answer:
Hello! answer: x = 20
Step-by-step explanation:
This is a complementary angle meaning it will add up to 90 degrees so...
20 × 4 = 80 80 - 10 = 70
70 + 20 = 90 therefore x = 20
D'andre was trying to make a rectangular frame that had a width of 24 inches and a length of 70 inches. He wanted to ensure his shape contained right angles, so he measured the diagonal and found that it was 74 inches long. Did D'andre construct a rectangle? Why or why not?
Answer:
yes
the sum of the squares of the width and length is equal to the square of the diagonal
Step-by-step explanation:
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
24^2 + 70^ = 576 + 4900 = 5476
square root = 74
