Answer:
8.307
Step-by-step explanation:
69 is not a perfect square, and none of its factors (1, 3, 23, 69) are perfect squares. Therefore, the best one can do in finding the square root of 69 is to use a calculator: √69 = 8.307 to three decimal places.
Note that 8² = 64 and that 9² = 81. Since 69 is between 64 and 81, it follows that the square root of 69 lies between 8 and 9, which agrees with the outcome given above.

A side of the triangle below has been extended to form an exterior angle of 156°. Find
the value of x.
Answer:
24°
Step-by-step explanation:
156° and x° form a straight line, and angles that form a straight line sum to 180°
Thus, 156° + x° = 180°
=> x° = 180° - 156° = 24°

When a bakery opened this morning, the ratio of the number of pineapple muffins to the number of mango muffins was 3 : 2. After 244 pineapple muffins were sold, the ratio of the number of pineapple muffins to the number of mango muffins changed to 3 : 5. How many pineapple muffins were there when the bakery opened this morning?
Answer:
(x+244)/y=3/2
x/y=3/5
y=5x/3
(x+244)/(x5/3)=3/2
x+244=3/2 . 5x/3
x+244=15x/6
6(x+244)=15x
6x+1464=15x
1464=15x-6x
1464=9x
x=1464/9
x≈ 162
mm=162*5/3=270
162:270 = 3:5
pm before = 270*3/2=405
405:270 = 3:2

Leah is sending out 32 party invitations. She gives 5 invitations to her Mom to give to family members. Leah mails a third of the rest. Write a numerical expression to describe how many invitations Leah has already mailed.
Answer:
9 of 32 invitations were mailed
fraction = 9/32
Decimal = this can be derived by dividing 9 by 32 = 0.28
Percentage = this can be derived by multiplying the decimal by 100 = 28%
Step-by-step explanation:
Number of invitations mailed = 1/3 x (total invitation - invitation mom delivered)
1/3 x (32 - 5)
1/3 x (27)
= 9
This figure can be expressed as a fraction
A fraction is a quantity that is not a whole number. In maths, a fraction usually has a numerator and a denominator.
The numerator is the number above. While the denominator is the number below
an example of a fraction = [tex]\frac{1}{2}[/tex]
1 is the numerator while 2 is the denominator
fraction = 9/32
Decimal = this can be derived by dividing 9 by 32 = 0.28
Percentage = this can be derived by multiplying the decimal by 100 = 28%

(hope it helps can i plz have brainlist :D hehe)
Step-by-step explanation:
(sorry if I'm wrong plz don't report)
Answer:
x=0.036232
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
34.5x+7=8.25
Step 2: Subtract 7 from both sides.
34.5x+7−7=8.25−7
34.5x=1.25
Step 3: Divide both sides by 34.5.
34.5x/34.5 = 1.25/34.5
x=0.036232

Step-by-step explanation:
Write and solve an equation to find the value of x and a missing angle in the triangle below.
Answer:
x = 27°, ∠JLK = 55°
Step-by-step explanation:
From the diagram in the question above,
The exterior angle of a triangle is equal to the sum of the two opposite side
3x+13 = 39+(2x+1)
3x+13 = 40+2x
collect like terms and solve for x
3x-2x = 40-13
x = 27°.
∠JKL = 2x+1
Substitute the value of x
∠JKL = 2(27)+1
∠JKL = 54+1
∠JKL = 55°
How many mL of medication are needed to last 10 days if the dose of medication is 2.5 tsp TID (three times a day)?
Answer:
369.7 mL of medication
Step-by-step explanation:
How many mL of medication are needed to last 10 days if the dose of medication is 2.5 tsp TID (three times a day)?
From the above question,
The dosage of the medication =
2.5 tsp 3 times a day
= 2.5 × 3 = 7.5 tsp per day.
Since
1 day = 7.5 tsp
10 days = x tsp
Cross Multiply
x = 10 × 7.5 tsp
x = 75 tsp of medication for 10 days.
Step 2
It is important to note that:
1 tsp = 4.929 mL
75 tsp = x mL
Cross Multiply
x = 75 × 4.929 mL
x = 369.669 mL of medication
Approximately = 369.7 mL of medication
g(x) = -3х (х^2– 36) (х – 6)

Pam has $60,000 in a savings account that earns 11% interest per year. The interest is not compounded. How much interest will she earn in 8 months?
Answer:
The amount of interest is $4,400
Step-by-step explanation:
To get the amount of interest, we use the simple interest formula
Mathematically;
I = PRT/100
I = interest
P is the amount deposited = $60,000
R is interest rate = 11%
t is time in years = 8/12 = 2/3
Substituting these values, we have
I = (60,000 * 11 * 2/3)/100
I = $4,400

Step-by-step explanation:
use CAH method (Cos angle = adjacent/hypotenuse)
Given adjacent = 5
Hypotenuse = 12,
[tex] \cos(x) = \frac{adjacent}{hypotenuse} \\ \cos(x) = \frac{5}{12} \\ x = {cos}^{ - 1} ( \frac{5}{12} ) \\ = 65.4deg(nearest \: tenth)[/tex]
