Two tour groups are visiting an aquarium. There are 20 children in one group and 22 children in the other. Along with the 2 group leaders, there are 5 additional adults between the two groups. If the cost per child is $9.00 and the total for both groups is $490, what is the cost per adult?
Answer:
The cost per adult is $16.
Step-by-step explanation:
Given that:
Total number of children = 20+22 = 42 children
Total number of adults = 2 + 5 = 7 adults
Total cost for both groups = $490
Cost per child = $9.00
Cost of children ticket = 9.00*42 = $378
Cost of adult tickets = 490-378 = $112
This is the cost for 7 adult tickets.
Cost per ticket = [tex]\frac{112}{7}[/tex] = $16
Hence,
The cost per adult is $16.
which of the following is equivalent to (Cd) to the fifth power
Answer:
The 3rd option is correct.
Step-by-step explanation:
This is because of an exponent rule that goes:
(xy)^z = x^z(y^z)
The whole thing gets raised to the power. Therefore only the 3rd one works (ps. if you can mark as brainliest that would be amazing, but if not that's fine)

Sultan needs enough tents for 28 people to sleep in. Each tent can fit 6 people. How many tents does he need?
Answer:
5 tents
Step-by-step explanation:
1 tent = 6 people
x tent = 28 people
Cross product
1 * 28 = 6 * x
28 = 6x
x = 28/6
= 4.67
Approximately x = 5 tents to an whole number
Therefore, he needs 5 tents for 28 people to sleep in
the base of a pyramid has n sides
write an expression for the number of faces on the pyramid
Answer: The expression for number of faces of a pyramid =1+n
Step-by-step explanation:
A Pyramid is a polyhedron or a three dimensional shape having a polygon base and all lateral faces are triangles .
Its base describe the number of other faces of it.
For example a triangular pyramid has a triangular base which gives rise to 3 lateral faces , and a rectangular pyramid has a rectangular base which give rise to 4 lateral faces and so on.....
So the total number of faces in a pyramid = base + lateral faces
If a pyramid has n sides therefore it give rise to n lateral faces such that
The total number of faces in a pyramid= 1+n .

Step-by-step explanation:
Jared started a new job. On the first day he had orientation and worked for 2 hours. On the second day he trained for 4 hours. After that, Jared worked 8 hours each day. If his first paycheck shows that he is being paid for 94 hours of work, how many days did he work a full 8-hour day?
Answer:
Jared worked 11 days as full 8-hour days.
Step-by-step explanation:
We have:
First day = 2 h
Second day = 4 h
After that = 8 h each day
Since his paycheck shows 94 hours of work, we can find the number of days that he works 8-hour day:
[tex] 94 h = 2 h + 4 h + 8 h*x [/tex]
Where x is the number of days that he works 8-hours.
[tex] 8 h*x = 88 h [/tex]
[tex] x = \frac{88 h}{8 h} = 11 [/tex]
Therefore, Jared worked 11 days as full 8-hour days.
I hope it helps you!

What is the measure, in degrees, of the angle marked B?
133
65
68
47
Answer:
[tex]\boxed {\boxed {\sf 133 \ degrees }}[/tex]
Step-by-step explanation:
According to the Exterior Angle Theorem, the exterior angle of a triangle is equal to the sum of the 2 remote and opposite interior angle.
[tex]d=a+b[/tex]
In this triangle, angle B is the exterior angle (d). The two interior angles are 68 degrees and 65 degrees ( a and b).
[tex]\angle B=68 \textdegree +65 \textdegree[/tex]
Add.
[tex]\angle B= 133 \textdegree[/tex]
This can also be solved using triangles and supplementary angles.
The angles in a triangle must add to 180 degrees. We have three angles: 68, 65, and an unlabeled angle we can call x.
[tex]68+65+x=180 \\133+x=180[/tex]
Subtract x from both sides.
[tex]133+x=180-133 \\x=47[/tex]
x is on a straight line with B, so they are supplementary and add to 180 degrees.
[tex]47+ \angle B= 180[/tex]
Subtract 47 from both sides.
[tex]47-47+ \angle B= 180-47\\\angle B= 133[/tex]
Angle B is equal to 133 degrees.

4. Simplify
Therefore, x = 10
Hope this helps :)
Answer:
=10
Add 4
to both sides of the equation 2−4=+6
2x-4=x+6 2−4+4=+6+4

Answer:
The statements that must be true are:
XY and JK form four right angles ⇒ B
XY ⊥ JK ⇒ C
JP = KP ⇒ E
m∠JPX = 90° ⇒ F
Step-by-step explanation:
From the given figure
∵ Line XY is the perpendicular bisector of the line segment JK
→ That means line XY is the line of symmetry of the line segment JK
∴ XY ⊥ JK ⇒ C
∵ XY ∩ JK at point P
∴ P is the midpoint of JK
∵ XY ⊥ JK
∴ ∠JPX, ∠KPX, ∠JPY, and ∠KPY are right angles
∴ XY and JK form four right angles ⇒ B
∵ The measure of the right angle is 90°
∴ m∠JPX = m∠KPX = m∠JPY = m∠KPY = 90°
∴ m∠JPX = 90° ⇒ F
∵ P is the midpoint of JK
∴ JP = KP ⇒ E

Work out the percentage change when a price of £10 is increased to £14.
Answer:
40%
Step-by-step explanation:
14-10 = 4, which is a 4 euro increase.
4/10 = 40%
Or we can see that 14/10 = 1.4, or 140%, which is a 40% increase

turquoise paint is made by mixing blue, green and yellow paint in the ratio 2.5 : 1.4 : 0.1 . how much of each colour is needed to make 1.5 litres of turquoise paint? write answers in the same order as the ratio (eg, blue, green, then yellow)
Answer: Blue color = 937.5 ml
green color = 525 ml
Yellow color= 37.5 ml
Step-by-step explanation:
Let the quantity of all kinds of paint required to make turquoise paint be 2.5 x(blue), 1.4 x( green), 0.1 x.(yellow).
Total turquoise color required =2.5x+1.4x+0.1x
[tex]\Rightarrow (2.5+1.4+01)x=1.5\\\\\Rightarrow\ 4x = 1.5\\\\\Rightarrow x=\dfrac{1.5}{4}\\\\\Rightarrow\ x=0.375[/tex] = 1.5 liters [given]
Blue color = 2.5 x 0.375 = 0.9375 liters = 937.5 ml [1 liter = 1000 ml]
green color = 1.4 x 0.375= 0.525 l = 525 ml
Yellow color= 0.1 x 0.375= 0.0375 =37.5 ml

Step-by-step explanation:
For a triangle, any 2 side lengths of the triangle must be greatee than the 3rd side.
Given a triangle with side lengths 11, 23 and x,
we have:
11 + 23 > x,11 + x > 23, and23 + x > 11.Therefore 34 > x and x > 12. => 12 < x < 34.
Answer:
second option
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is
difference of 2 sides < x < sum of 2 sides , that is
23 - 11 < x < 23 + 11, thus
12 < x < 34
2*10⁴-7³ please help
Answer:
19657
Step-by-step explanation:
By PEMDAS, we know we have to calculate the exponents first, then multiply the 2, and then subtract the 7³
2*10⁴ = 20000
20000 - 7³ = 19657
