Answers
Answer:
G 7
Step-by-step explanation:
If t= 27 when s=3 27/3=9
the t=63 when s= 7 63/7= 9
Answer:
G
Step-by-step explanation:
Given that s varies directly with t then the equation relating them is
s = kt ← k is the constant of variation
To find k use the condition when t = 27, s = 3 , then
3 = 27k ( divide both sides by 27 )
[tex]\frac{3}{27}[/tex] = k, that is
k = [tex]\frac{1}{9}[/tex]
s = [tex]\frac{1}{9}[/tex] t ← equation of variation
When t = 63, then
s = [tex]\frac{1}{9}[/tex] × 63 = 7 → G

At most, Alana can spend $40 on carnival tickets. Ride tickets cost $4 each, and food tickets cost $2 each. Alana buys at least 16 tickets. The system of inequalities represents the number of ride tickets, r, and the number of food tickets, f, she buys.
Answers
Answer:
4 is the maximum number of ride tickets she can buy
Step-by-step explanation:
Here, r represents the number of ride tickets and f represents number of food tickets.
The system of inequalities is given as:
r+f\geq 16 ....[1]
4r+2f\leq 40 .....[2]
To solve Mathematically:
Multiply equation [1] by -2 we have;
-2r-2f \leq -32 .....[3]
Add equation [2] and [3] we have;
2r \leq 8
Divide both sides by 2 we have;
r \leq 4
Since r must be less than or equal to 4.
You can also see the graph of the given system of inequalities as shown below.
The intersection point is, (4, 12)
Therefore, the maximum number of ride tickets she can buy is, 4

Layala and Zahra have 2700 marbles in the ratio of 2:7. How many marbles Zahra must have gave away so that they both would have the same number of marbles?
Answers
Answer:
1500
Step-by-step explanation:
Given that :
Total number of marbles held by Layala and Zahra = 2700
Ratio = 2 : 7
Layala's share of marbles : (2 / (2+7)) * 2700
= 2/9 * 2700
= 600
Zahra's share of marble : (7 / (2+ 7)) * 2700
= 7 / 9 * 2700
= 2100
Hence, Zahra must have given away (2100 - x) = 600
2100 - 600
= 1500 marbles, so that both Zahra and Layala have the same number of marbles

b. 6 units
Step-by-step explanation:
a. By the property of intersecting tangent and secant outside of a circle, we have:
[tex] m\angle P = \frac{1} {2} \times \bigg(m\widehat{QS} - m\widehat{QR}\bigg) \\\\
m\angle P = \frac{1} {2} \times \bigg(150\degree - 80\degree\bigg) \\\\
m\angle P = \frac{1} {2} \times 70\degree \\\\
\huge\purple {\boxed{m\angle P =35\degree}} \\[/tex]
b.
[tex] PS = PR + RS = 4 + 5 = 9\: units\\[/tex]
By the property of intersecting tangent and secant outside of a circle, we have:
[tex]
PQ^2 = PR\times PS\\\\
PQ^2 = 4\times 9\\\\
PQ^2 = 36\\\\
PQ =\pm \sqrt {36} \\\\
PQ=\pm 6\\[/tex]
Since, PQ can not be a negative number.
So, PQ = 6 units.

The smaller triangle was dilated to form the larger triangle. What is the value of x? A smaller triangle has side lengths of 5, 13, 12. A larger triangle has side lengths of x, blank, 18. 6.9 7.5 10 11
Answers
Answer:
x = 7.5
Step-by-step explanation:
Dilation is a transformation in which the size of a given figure is either increased or decreased by a scale factor.
Given that the length of sides of the smaller triangle are; 5, 13, 12.
Given also that the length of the dilated triangle are; x, blank, 18.
Comparing the length of the last sides of the two triangles, we have;
(scale factor x 12) + 12
= ([tex]\frac{1}{2}[/tex] x 12) + 12
= 6 + 12
= 18
Thus the scale factor for the dilation is [tex]\frac{1}{2}[/tex]. So that:
x = ([tex]\frac{1}{2}[/tex] x 5) + 5
= 2.5 + 5
= 7.5
x = 7.5
And also,
blank = ([tex]\frac{1}{2}[/tex] x 13) + 13
= 6.5 + 13
blank = 19.5
Therefore, the length of the sides of dilated triangle are: 7.5, 19.5, 18
Answer:
7.5

Two pizza parlors in town are offering special rates to attract group reservations. Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered. Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered. Compare the costs of holding an event at the two pizza parlors.
Write and solve a system of linear equations to model the cost of an event at each pizza parlor.

b. Write an equation to represent the cost for a party at Napoli’s Pizza.
c. What is the solution to the system of equations? (label your answers)
Answers
Answer:
x = 2 pizzas
Step-by-step explanation:
Let
x = number of pizza ordered
Stella’s Pizza charges $16.00 room rental fee and an additional $8.00 for each pizza ordered.
cost for a party at Stella’s Pizza = 16 + 8x
Napoli’s Pizza charges $24 for the room rental fee and an additional $6.00 for each pizza ordered.
cost for a party at Napoli’s Pizza = 24 + 6x
Equate the cost for a party at Stella’s Pizza and cost for a party at Napoli’s Pizza
16 + 8x = 24 + 6x
8x - 6x = 24 - 16
2x = 8
x = 8/4
= 2
x = 2

A comer store sells two kinds of baked goods: cakes and pies. A cake costs $8 and a pie costs $11. In one
day, the store sold 11 baked goods for a total of $112. How many cakes did they sell?
a. 3 cakes
c. 2 cakes
b 11 cakes
d. 8 cakes
Answers
Answer:
8 number of cakes were sold.
Step-by-step explanation:
Out of 12 baked goods sold , let the number of cakes sold be x in number and pies sold were 12 − x in number. Total sell was $ 144 , 1 cake costs $ 14 and 1 pie costs $ 8 ∴ 14 ⋅ x + ( 12 − x ) ⋅ 8 = 144 or 14 x − 8 x = 144 − 96 or 6 x = 48 ∴ x = 8 Therefore, 8 cakes were sold [Ans]
Answer:
3 cakes
Step-by-step explanation:
3x8=24
112-24=88
88/11=8
3cakes +8 pies= 11 baked goods

A direct proportion means the ratio of p:u is a constant numberThis constant number is denoted by kan example of this is, say for every 1 chicken you buy there are 2 legs which is ratio 1:2 which is [tex]\frac{1}{2}[/tex] so if you add more chickens, you add more legs, 2 chickens means 4 legs, 8 chickens means 16 legs, which is [tex]\frac{1}{2}= \frac{2}{4} =\frac{8}{16} =0.5[/tex] so the constant number is 0.5, so this a direct proportionThe two values grow at the same rateUsing the triangle below, find the value of x.

The angle measures of a triangle are shown:
Angle A: (5x – 5) degrees
Angle B: (3x + 3) degrees
Angle C: (5x) degrees
The sum of the measures of the three angles is equal to 180°. What is the measure of Angle B?
Answers
Answer:
∠ B = 45°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Sum the 3 given angles and equate to 180, that is
5x - 5 + 3x + 3 + 5x = 180, simplify
13x - 2 = 180 ( add 2 to both sides )
13x = 182 ( divide both sides by 13 )
x = 14
Thus
∠ B = 3x + 3 = 3(14) + 3 = 42 + 3 = 45°
