It sells twice as many kitten as lizards:
Kittens sold = 15 x 2 = 30 total kittens.
It sells 6 times the amount of fish:
Fish sold = 6 x 30 = 180 total fish.
Lizards = 15
Kittens = 30
Fish = 180
Answer:
They sell 225 pets each week.
Step-by-step explanation:
Let f be fish, k be kittens, and l be lizards.
[tex]f[/tex]÷6=[tex]k[/tex]
[tex]k[/tex]÷2=[tex]l[/tex]
If [tex]l=15[/tex], then:
[tex]k=30\\f=180[/tex]
180+30+15=225 pets
They sell 225 pets each week.

Having problems with this
Answer:
45
Step-by-step explanation:
Since angles 4 and 2 are the same, we will have to do x+30 is = to 2x+15. After that x= 15. Substitute x in x+30. Which results in 45
Answer:
45°
Step-by-step explanation:
Corresponding angles are equal. ∠4 and ∠2 are equal.
[tex]x+30=2x+15[/tex]
Add -x and -15 on both sides of the equation.
[tex]30-15=2x-x[/tex]
[tex]15=1x[/tex]
∠4 = x+30
Put x as 15 in the equation.
[tex](15)+30[/tex]

What is the perimeter?
Answer:
91+c
Step-by-step explanation:
The equation to find the perimeter of the triagle is every side added together. We know 2 sides which means we add them to get 91. Then we know we don't know the next number but we add it so we just put the c where the next number to be added would go.
AB is parallel to CD . Find the measure of each numbered angle. I NEED HELP ON 8 AND 9 ASAP
Answer:
Question (8). m∠1 = 142°
m∠2 = 300°
Question (9). m∠1 = 73°
m∠2 = 82°
Step-by-step explanation:
Question (8). m∠1 + 38° = 180° [Supplementary angles]
m∠1 = 180 - 38
m∠1 = 142°
m∠x = 38° [Alternate interior angles]
m∠y = 22° [Alternate interior angles]
Now, m∠2 = 360° - (m∠x + m∠y)
= 360° - (38 + 22)°
m∠2 = 300°
Question (9). m∠RMN + 98° = 180°
m∠RMN = 180 -98
= 82°
m∠RMN = m∠ARM = 82°
m∠2 = 82°
m∠SNM = 73° [Vertical angles]
m∠SNM = m∠OSR = 73°[Corresponding angles]
m∠1 = 73°
Can anybody help me solve for surface area?
(Formula=add all the areas of the faces)
Answer:
230.3cm^2
Step-by-step explanation:
surface area: sum of all faces
base: 12 x 2.5 = 30cm^2
back: 84 cm ^2
cross section x 2 = 7 x 2.5 = 17.5
use Pythagoras theorem to find the width of slope: 7^2 + 2.5^2 = 49 + 6.25 = 55.25. square root of 55.25 = 7.4
so, area of slope : 7.4 x 12 = 88.8cm^2
sum of all areas: 114 + 106.3 = 230.3

i need help ASAP
Answer:
x = -18
Step-by-step explanation:
5 ( x + 9 ) = -45
→ Expand out the brackets to simplify the equation
5x + 45 = -45
→ Minus 45 from both sides to isolate 5x
5x = - 90
→ Divide both sides by 5 to isolate x
x = -18
Answer:
x= -18
Step-by-step explanation:
5*(x+9)=-45
:5 :5
x+9=-9
-9 -9
x= -9-9
x= -18

Kurt and Drew walk the same distance to school. Their start and end times are different.
Who got to school faster, and by how many minutes?
Kurt
Answer:
Option C.
Step-by-step explanation:
Kurt started for the school at 07:35 and ends at 08:25.
Time taken by Kurt to reach the school
= 08:25 - 07:35
= (07 hours + 85 minutes) - (07 hours + 35 minutes) [Since 08 hours + 25 minutes = 07 hours + (60 + 25)minutes]
= 85 minutes - 35 minutes
= 50 minutes
Time taken by Drew to reach the school
= 08:30 - 07:55
= (07 hours + 90 minutes) - (07 hours + 55 minutes) [Since 08 hours + 30 minutes = 07 hours + (60 + 30)minutes]
= 90 minutes - 55 minutes
= 35 minutes
Difference in the time taken by Kurt and Drew = 50 - 35 = 15 minutes.
Therefore, Drew is 15 minutes faster than Kurt.
Option C. is the answer.

Which is a zero of the quadratic function f(x) = 16x2 + 32x − 9? x = –5.25 x = –2.25 x = –1.25 x = –0.25
Answer:
answer b -2.25
Step-by-step explanation:
The zero of the quadratic function f(x) = 16x2 + 32x − 9 is -2.25
How to determine the zero?We have:
f(x) = 16x^2 + 32x - 9
Next, we test the options.
x = –5.25
f(-5.25) = 16(-5.25)^2 + 32(-5.25) - 9
Evaluate
f(-5.25) = 264 --- this is false
x = –2.25
f(-2.25) = 16(-2.25)^2 + 32(-2.25) - 9
Evaluate
f(-2.25) = 0 ---- this is true
Hence, the zero of the quadratic function f(x) = 16x2 + 32x − 9 is -2.25

What is the approximate loudness of a rock concert with a sound intensity of 10–1?
A.) 2 Db
B.) 22 Db
C.) 60 Db
D.) 110 Db
Answer:
22
Step-by-step explanation:
Im sure because my sister got the same question on a test and she put 22 and got it right
The loudness of a rock concert with a sound intensity of 10⁻¹ is 110 dB.
EquationAn equation is an expression used to show the relationship between two or more variables and numbers.
Given that:
L = 10log(I / I₀)
Where L is the loudness, I is the sound intensity and I₀ = 10⁻¹².
For I = 10⁻¹:
L = 10log(10⁻¹ / 10⁻¹²) = 110 dB
The loudness of a rock concert with a sound intensity of 10⁻¹ is 110 dB.

tom gets a bonus of 30% of £96
sally gets a bonus of £31.40
work out the difference between the bonus that tom gets and the bonus that sally gets
Answer:
The difference between the bonus is £2.6
Step-by-step explanation:
First, you have to calculate the amount that Tom get for his bonus. So you have to multiply 30% to £96 :
[tex] \frac{30}{100} \times 96 = 28.8[/tex]
Next, you have to subtract Tom's amount from Sally's amount because Sally has the higher amount of bonus than Tom :
[tex]31.4 - 28.8 = 2.6[/tex]
