Find the surface area of the
rectangular prism.
3 cm
10 cm
7 cm
[?] sq cm
Answer:
Step-by-step explanation:
There are six faces on the prism:
Two faces are 7 cm by 10 cm, area = 7×10 = 70 cm² each
Two faces are 7 cm by 3 cm, area = 7×3 = 21 cm² each
Two faces are 10 cm by 3 cm, area = 10×3 = 30 cm² each
surface area = 2(70) + 2(21) + 2(30) = 140 + 42 + 60 = 242 cm²
d^2 + 2d - 8 = 0
explain plz
Answer:
d^2 +2d-8=0
first pick two numbers which add up to make +2 and by multiplying those two numbers they should be able to create -8.
so for example 4 and 2
4-2=2
4 x -2= -8
so now factorise:
d^2 +2d-8=0
d^2+4d-2d -8=0
d(d+4)-2(d+4)=0
d+4=0 d-2=0
d=-4 d=2

round 30.25 to the nearest hundreth
Answer
Answer:
30.3
Step-by-step explanation:
Think about this the 5 in the hundredth place rounds up not down so it would be 30.3 or 30.30 same thing.
the formula an=1.5 (an-1) with an initial value of 40 describes a sequence. Use the explicit formula to determine the 5th term of the sequence.
[tex]\text{If } a_n=1.5(a_n-1) \text{ this is a geometric sequence with a ratio of 1.5. The first term is 40. }a_n=40(1.5)^{n-1},\ a_5=40(1.5)^4=202.5[/tex]

Answer:
x = 28
m∠ACD = 68°
Step-by-step explanation:
∠BAE ≅∠DAC because they are vertical angles
∠ACD = 180 - 124 = 56°
to find 'x': 56 + 2x + (180 - 4x) = 180
236 - 2x = 180
-2x = -56
x = 28
m∠ACD = 180 - 4(28) = 180 - 112 = 68°

In 2019, Chris made $142,000 as a dentist. Social Security tax was 6.2% to a maximum income of $132,900.
Medicare tax was 1.45% of all income. How much did Chris pay in FICA Taxes?
Type your answer
Answer: $10,298.80
Step-by-step explanation:
Chris made more than the limit required for the Social Security tax so his Social Security tax will be based on the maximum amount of $132,900.
His Social Security tax is therefore:
= 6.2% * 132,900
= $8,239.80
There are no limits for Medicare so Chris will pay taxes on the whole amount he earned of $ 142,000.
Medicare = 1.45% * 142,000
= $2,059
FICA tax = Social security + Medicare
= 8,239.80 + 2,059
= $10,298.80

i think im to late sorry
Step-by-step explanation:
find the value of x in the diagram below
Answer:
x = 12
Step-by-step explanation:
ZY is a midsegment and is half the measure of SQ, that is
x + 2 = [tex]\frac{1}{2}[/tex] (3x - 8) ← multiply through by 2 to clear the fraction
2x + 4 = 3x - 8 ( subtract 2x from both sides )
4 = x - 8 ( add 8 to both sides )
12 = x
A particle travels 24.6 km in 30 minutes. Find the
speed of the particle in
(i) km/h,
(ii) m/s.
Answer:
See the solutions below
Step-by-step explanation:
Given data
Distance = 24.6km
in meters= 24.6*1000= 24600m
time= 30 minutes
in seconds= 30*60= 1800
int hours= 0.5 hour
speed of the particle in
(i) km/h= 24.6/0.5= 49.2 km/h
(ii) m/s.= 24600/ 1800= 13.66 m/s
