In RST shown below, altitude SU is drawn to RT at U. If SU = h, UT = 12, and RT = 42, what is the value of h to the nearest tenth?
Answer:
assuming angle RST=90 degrees
h=19
Step-by-step explanation:
RU/h=h/UT
RU=RT-UT=42-12=30
30/h=h/12
h^2=360
h=18.97 rounded to nearest tenths=19
The length of the rectangle is 5 cm longer than twice its width. If the perimeter of the rectangle is 88 cm what is the width? pls help
l = 5 + 2w.
P = 88 cm.
P = 2 ( l + w )
88 cm = 2 ( (5 + 2w) + w)
88 cm = 2 (5 + 3w)
88 cm cm = 10 + 6w
88 cm cm - 10 = 6w
78 cm = 6w
78 cm : 6 = w
13 cm = w
The width is 13 cm.
Find the measure of angle b
Answer:
26˚
Step-by-step explanation:
Since there is already two angles (The square in the corner shows that the angle is 90˚)
So subtract 90˚ with 64˚ which is 26˚
Answer:
this whole angle is equal to 90°
so the value of angle b = 90°-64°
so the value of b= 26.
When do we use pooling in inference?
Answer:
There are two versions of this test, one is used when the variances of the two populations are equal (the pooled test) and the other one is used when the variances of the two populations are unequal (the unpooled test).

What is the solution to the equation −4(2y − 4) − 4y = 4? (put number answer only)
Answer:
y=1
Step-by-step explanation:
Let's solve your equation step by step.
Step 1: Simplify both sides of the equation.
−4(2y−4)−4y=4
(−4)(2y)+(−4)(−4)+−4y=4(Distribute)
−8y+16+−4y=4
(−8y+−4y)+(16)=4(Combine Like Terms)
−12y+16=4
−12y+16=4
Step 2: Subtract 16 from both sides.
−12y+16−16=4−16
−12y=−12
Step 3: Divide both sides by -12.
y=1

Phil's height is 51.2 cm, suzanne's height is 5'4", and suzanne's shadow lengthat gobblers knob is 76.2
Answer:
[tex]P_1 = 24cm[/tex]
Step-by-step explanation:
Represent:
Phil's height with P
Suzanne's height with S
Phil's shadow with P1
Suzanne's shadow with S1
So, we have:
[tex]P = 51.2cm[/tex]
[tex]S = 5'4"[/tex]
[tex]S_1 = 76.2cm[/tex]
Required
Calculate the length of Phil's shadow --- Missing part of question
To do this, we make use of the following equivalent ratio.
[tex]P:S = P_1 : S_1[/tex]
Convert [tex]S = 5'4"[/tex] to cm
[tex]S = 5ft\ 4in[/tex]
[tex]S = (5*30.48+ 4*2.54)cm[/tex]
[tex]S = 162.56cm[/tex]
Substitute values for P, S and S1
[tex]51.2cm : 162.56cm = P_1 : 76.2cm[/tex]
Express as fraction
[tex]\frac{51.2cm}{162.56cm} = \frac{P_1 }{ 76.2cm}[/tex]
Make P1 the subject
[tex]P_1 = 76.2cm * \frac{51.2cm}{162.56cm}[/tex]
[tex]P_1 = 76.2cm * \frac{51.2}{162.56}[/tex]
[tex]P_1 = \frac{76.2cm * 51.2}{162.56}[/tex]
[tex]P_1 = \frac{3901.44cm}{162.56}[/tex]
[tex]P_1 = 24cm[/tex]
Hence, the length of Phil's shadow is 24 cm

B. 4
C. 5
D. 6
I will give you 30
points if you anser!
Answer:
3
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
If the two number cubes are a standard six sided dice then the total of ways he can roll for the sum of 6 is 3
1+5 = 6
2+4 = 6
3+3 = 6

Choose the method of pay that would result in the most earnings for one month on sales of 73,620
Answer:
Step-by-step explanation:
For option A: Earning = 0.06 x $73,620 = $4,417.20
For option B: Earning = $3,000 + 0.02 x $73,620 = $3,000 + $1,472.40 = $4,472.40
For option C: Earning = 0.04 x $50,000 + 0.09 x ($73,620 - $50,000) = $2,000 + 0.09 x $23,620 = $2,000 + $2,125.80 = $4,125.80
For option D: Earning = 0.05 x $35,000 + 0.07 x $(73,620 - 35,000) = $1,750 + 0.07 x $38,620 = $1,750 + $2,703.4 = $4,453.40
Therefore, the method that yields the most earning is monthly salary of $3,000 plus 2% commission on all sales .
Answer:
b.
Monthly salary of $3,000 plus 2% commission on all sales.

A piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.
Find both the explicit and recursive rule for this geometric sequence.
Answer:
sorry i am struggling the same
Step-by-step explanation:
2+2=4
The answers to each part are mentioned below.
What is geometric sequence? What is an exponential function? Differentiate between equation and expression? geometric sequence : A geometric sequence is a special type of sequence where the ratio of every two successive terms is a constant. This ratio is known as a common ratio.function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is a piece of paper is 0.1 millimeter thick. When folded, the paper is twice as thick.
We can write the geometric sequence as -
0.1, 0.2, 0.4, 0.8 ......
The explicit formula for a geometric sequence is of the form -a{n} = arⁿ ⁻ ¹
where [r] is the common ratio.
The recursive formula for a geometric sequence is of the form -a{n} = a{n - 1}rFor the geometric sequence -
0.1, 0.2, 0.4, 0.8 ......
The explicit formula will be : a{n} = (0.1)(2)ⁿ ⁻ ¹ The recursive formula will be : a{n} = 2a{n - 1}If the paper is folded 7 times, we can write the thickness as -
y{7} = (0.1)(2)⁶ = (0.1) x (64) = 6.4
To surpass the Mount Everest, we can write -
8850 < (0.1)(2)ⁿ ⁻ ¹
(2)ⁿ ⁻ ¹ > 88500
(2)ⁿ/2 > 88500
(2)ⁿ > 177000
n log(2) > log(177000)
n > {5.25/log(2)}
n > 17.44
n > 18
Therefore, the answers to each part are mentioned above.

A family went to a basketball game. They parked the car in a parking lot which charged $5. The cost per ticket was $24. Write an equation for the total cost of going to the basketball game, where y is the total cost an x is the total number of people. If the family spent $173, how many people went to the game?
Answer:
7 people went to the basketball game.
Step-by-step explanation:
Giving the following information:
They parked the car in a parking lot which charged $5. The cost per ticket was $24.
To calculate the number of people, we need to use the following formula:
Total cost (y)= x*24 + 5
173 = 24x + 5
168/24 = x
7 = x
7 people went to the basketball game.
