I’m having trouble with this plz help.
Answer:
The answer is 56. Here's why:
Step-by-step explanation:
Pythagorean Therom works for any right triangle, and it states (a)²+(b)²=(c)². A and B are the height and base, and C is the hyptoanuse. We don't know the height, but we know the rest of the information:
(a)²+(33)²=(65)². This simplifies to (a)²+1089=4225. If we subtract 1089 from each side, we get (a)²=3136. The √3136 (Sqaure root of 3136) is 56.
helpp me thx show work
Answer:
x= 25°
Step-by-step explanation:
3x-10 = 25 + x + 15 (ext ∠ of triangle equals to the sum of interior opposite ∠'s)
3x - x = 40 +10
2x= 50
x= 50/2
x= 25°
does anyone know equivalent expressions for these: y+4t+5y+3(3t+9y) and 9(y+4y+5)
Answer:
y + 4t + 5y + 3 (3t + 9y) = 13t + 33y
9 (y + 4y + 5) = 45y + 45

-6= b/18 does any one no this
Answer:
The correct answer is b = -108
Solve for b by simplifying both sides of the equation, then isolating the variable.
~Hoped this helped~
~Brainiliest, please?~
Answer:
[tex]b = - 108[/tex]
Step-by-step explanation:
[tex] \frac{b}{18} = - 6[/tex]
Lets multiply both the sides by 18.
[tex] = > \frac{b}{18} \times 18 = - 6 \times 18[/tex]
[tex] = > b = - 10 8[/tex]

Barbara wants to buy some glittery heart-shaped beads to make friendship bracelets. The beads she wants come in a small pack with 90 beads or a large pack with 300 beads. The small pack costs $3.60, while the large pack costs $9.00. Which pack is the better value? small pack ll large pack
Answer:
The large pack is a better deal!
Step-by-step explanation:
so first we need to figure out how much the individual beads cost.
Small pack: $ 3.60÷90 = 0.04 cents per bead
Large pack: $9.00 ÷ 300 = 0.03 cents per bead
Hope this helps!!
Have a great day!!

Answer:
0.5
Step-by-step explanation:
how you would solve this is 5 plus 3 plus 2 which will equal 10 (this ten will be your denominator) after that you look at how many blue sections there are (5). so 5 out of 10 of them are blue so your fraction would be 5/10. then you will reduce the fraction to 1/2. the question wants you to put this in decimal form so you will divide the 1 by 2 so in decimal form this is 0.5.

The difference between the roots of the quadratic equation x^2-14x+q=0 is 6. Find q.
Answer:
The value of q is 40
Step-by-step explanation:
In the quadratic equation ax² - bx + c = 0, where
a = 1
b is the sum of its two roots
c is the product of its two roots
Assume that the roots of the quadratic equations are x and y
∵ The quadratic equation is x² - 14x + q = 0
∴ a = 1 , b = 14 and c = q
∵ b is the sum of its two roots
∵ Its roots are x and y
∴ x + y = 14 ⇒ (1)
∵ The difference between the roots is 6
∴ x - y = 6 ⇒ (2)
Now we have a system of equation to solve it
Add equations (1) and (2)
∴ 2x = 20
- Divide both sides by 2
∴ x = 10
Substitute the value of x in equation (1) or (2) to find y
∵ 10 + y = 14
- Subtract 10 from both sides
∴ y = 4
∵ c is the product of the two roots
∴ c = 10 × 4 = 40
∵ c = q
∴ q = 40
The value of q is 40
