Hello There!
So the sum of the cakes (y) and cookies (x) is 64
so x + y = 64
It says that the amount of cookies he sold was 4 less then 3 times the number of cakes he sold
x = cookies
y = cakes
he sold 3 times the amount of cakes (y) - 4
so x=3y-4
So we can conclude that the answer would be D

Step-by-step explanation:
A 1,300 kg car moving at 20 m/s and a 900 kg car moving at 15 m/a in precisely opposite directions crash head on. If we consider this event to be a perfectly inelastic collision, what is the speed of the cars after the impact?
Answer:
17.96m/s
Step-by-step explanation:
Based on law of conservation of momentum;
m1u1 +m2u2 =(m1+m2)v
v is the velocities of the car after impact
Substitute the given values
1300(20)+900(15) = (1300+900)v
26000 + 13500 = 2200v
39500 = 2200v
v = 39500/2200
v = 17.96m/s
Hence the speed of the cars after impact is 17.96m/s

Connor and Angie helped take attendance during their school's practice
fire drill. Connor counted 470 in attendance and Angie counted 479. The
actual attendance was 470. What is the percent error? (ROUND TO THE
NEAREST TENTH.) *
0.019
1.2%
1.9%
12%
Answer: 1.9%
Step-by-step explanation:
The percent error formula is [tex]\frac{accepted-experimental}{accepted}[/tex] so input our values also keep in mind when we do percent error we use absolute error which means no negative percentages so 470-479/470= -9/470 or 9/470
as a decimal 9/470 is 0.019 or 1.9% so the answer is 1.9%
The bus fare for 8 passesngers is Rs. 384, how many more passengers can travel in the bus if the bus fare amounts to Rs. 576?
Answer:
12 passengers so four more can travel in the bus.
Step-by-step explanation:
384/8= rs 48 per person.
amount= 576
576/48 = 12 passengers.
Step-by-step explanation:
here
8 passengers=Rs. 384
1 passenger= Rs. 384/8
=Rs. 48
Rs. 576= ? passengers
now,
Rs. 576/ 48
= 12passengers
12 passengers - 8 passengers
= 4 passengers
therefore, 4 more passengers can travel in the bus fare amount to Rs. 576.

M is directly proportional to R cubed a)R = 4, M = 160 find M when R = 2 b) work out the value of R when M=540
Answer:
a k (proportionality constant) = 2.5
b. r = 6
Step-by-step explanation:
Here, we want to solve a variation
m = k * r^3
160 = k * 4^3
160 = 64k
k = 160/64
k = 2.5
b) secondly;
From;
540 = 2.5 * r^3
r^3 = 216
r = cube root of 216
r = 6

Answer:
n = -20
Step-by-step explanation:
-7 + [tex]\frac{n}{5}[/tex] = -11
*multiply both sides by 5*
-35 + n = -55
*add 35 to each side*
n = -55 + 35
*calculate the sum*
n = -20

Brenda has 14 fewer apps than Caleb. If Caleb deleted 5 apps, then he would have twice as many as Brenda. How many apps do Brenda and
Caleb have together?
Answer:
42
Step-by-step explanation:
Because Brenda has 14 fewer apps and he deleted 5 apps and he now has twice as many as brenda so 14 + 14 =28 so he had 33 before but remember 33- 5 + 28 so 14 + 28 + 42

Step-by-step explanation:
Explaining just 1st and 4th
1.The number 3.498 is bigger than 3.49 because it's basically this number 3.490
The same thing happens in 2nd and 3rd number 3.49 > 3.40
And the last number I think I don't have to explain :-)
4.700.088 is bigger because 700.08 is smaller
700.080

XZW XYV find the perimeter of XZW?
PLS HELP
9514 1404 393
Answer:
180 units
Step-by-step explanation:
The perimeter of ∆XYV is ...
Pxyv = XY +YV +VX
Pxyv = 29 +31 +40 = 100
The triangles are similar, so the scale factor from ∆XYV to ∆XZW applies to the perimeter. That scale factor is ...
WX/VX = (32+40)/40 = 1.8
Then ...
Pxzw = 1.8 × Pxyv = 1.8 × 100
Pxzw = 180 . . . units

8 + 25 x 2 to the power of 2
Answer:
3,364
Step-by-step explanation:
8 + 25 x 2
To solve this one, you multiply first according to PEMDAS. So,
25*2= 50
It is now 8+50 so you add that and you get 58
Now 58 with a power of 2 can als be written as 58^2
Basically you multiply 58 two times.
58*58=3,364
3,364
