Two of the angles in a triangle measure 51° and 25°. What must be the measure of the third angle?
Answer:
The measure of the third angle must be 104°
Step-by-step explanation:
Interior Angles of a Triangle
In any given triangle, the sum of its interior angles is 180°.
We are given the angles x=51° and y=25°. To find the third angle, z, we set up the equation:
x + y + z = 180
Solving for z:
z = 180 - x - y
Substituting:
z = 180 - 51 - 25
z = 104°
The measure of the third angle must be 104°
Ok pls help me with this
Answer: x = 2
Step-by-step explanation:
The rule for reflecting over x = 2 is that y remains the same and you add how many units x = 2 is from the point.
x = 2 is has the coordinate of x = 2 and y = the y coordinate of the point.
A (-1, 1) Since the y coordinate of (-1, 1) is 1, x = 2 - (2, 1)
Add 3 units to 2, the x coordinate since -1, 1 is 3 units from 2, 1
2,1 --> 5, 1

A submarine is 100 feet below the ocean's surface. If it descends 248 feet, what is its' new depth?
PLLSSSS HURRY
Answer:
348 feet
Step-by-step explanation:
Answer:
-348
or 348 feet under the oceans surface
Step-by-step explanation:
since your already 100 feet below the surface, if you go down(descends) another 248 feet. You subtract 248 from -100, you get -348.
So your 348 feet below sea level.

h(t)=- 16t^2 +16t+12 zeros of the parabola
Step-by-step explanation:
h(t) = -16t² + 16t + 12
h(t) = -4(4t² - 4t - 3)
h(t) = -4(2t - 3)(2t + 1)
When h(t) = 0, we have t = 1.5 or t = -0.5.
Hence the zeroes are 1.5 and -0.5.
rename the quadratic function f(x)=-2(x+4)^2-5 in standard form.
Answer:
function: x=-4
y-intercept: f(0)=-37
Step-by-step explanation:
hope this helps!
The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:
f(x) = -2x² - 16x - 37.
What is a function?A function has an input and an output.
A function can be one-to-one or onto one.
It simply indicated the relationships between the input and the output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
To rename the quadratic function f(x) = -2(x + 4)^2 - 5 in standard form, we need to expand and simplify the expression:
f(x) = -2(x + 4)² - 5
f(x) = -2(x² + 8x + 16) - 5
f(x) = -2x² - 16x - 32 - 5
f(x) = -2x² - 16x - 37
Therefore,
The quadratic function f(x) = -2(x + 4)^2 - 5 in standard form is:
f(x) = -2x² - 16x - 37.

Answer
n = 30
Explanation
To solve for n, you have to isolate it by 'getting rid' of the 18, 2, and negative sign.
You 'remove' these numbers in backward PEMDAS.
So to 'remove' the 18, you subtract both sides by 18.
3-18 = -15
-n/2+18-18 = -n/2
So now you are left with -15 = -n/2.
To 'get rid' of the 2, you multiply each side by 2.
-15×2 = -30
-n/2×2 = -n
And now you have -30 = -n.
To 'get rid' of the negative sign, you multiply both sides by -1.
-30×-1 = 30
-n×-1 = n
So you get 30 = n or n = 30.

Which of the b-values satisfy the following inequality? 5 < b-3
a. b=8
b. b=9
c. b=10
Answer:
the values 9 and 10 satisfy the given inequality.
Step-by-step explanation:
Given inequality is:
[tex]5<b-3[/tex]
In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality
Putting b = 8
[tex]5<8-3\\5 <5[/tex]
The inequality is not true for b=8.
Putting b=9
[tex]5<9-3\\5<6[/tex]
As the inequality is true for b=9, it satisfies the inequality.
Putting b=10
[tex]5<10-3\\5<7[/tex]
As the inequality is true for b=10, it satisfies the inequality.
Hence,
the values 9 and 10 satisfy the given inequality.
Answer:
The answer is b=9 and b=10

The mistake in her steps.
Solution:
We have,
[tex]2x^4+2x^3-x^2-x[/tex]
The correct steps are shown below.
Step 1: Taking out x as common factor.
[tex]=x(2x^3+2x^2-x-1)[/tex]
Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.
[tex]=x(2x^2(x+1)-1(x+1))[/tex]
Step 3: Taking out (x+1) as common factor.
[tex]=x(2x^2-1)(x+1)[/tex]
She incorrectly factored -1 from the second group of terms.
Therefore, the correct option is B.

Step-by-step explanation:
Given

Required
Find the number of blue paints in 12 gallons
Start by representing the blue part of the ratio as a fraction
[tex]Y : B = 3 ; 2[/tex]
[tex]B = \frac{2}{2 + 3}[/tex]
[tex]B = \frac{2}{5}[/tex]

A unit of gas costs 4.2 pence.
On average Ria uses 50.1 units of gas a week.
She pays for the gas she uses in 13 weeks.
Work out an estimate for the amount Ria pays.
Answer:
2735.46 pence or £27.35
Step-by-step explanation:
if she uses 50.1 units a week, in 13 weeks she will use 651.3 units. the cost for 651.3 units is 2735.46 pence. We can round this to £27.35.
The required cost of the gas as of the 13-week usage of gas is 2735.46 pence.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A unit of gas costs 4.2 pence. On average Ria uses 50.1 units of gas a week. She pays for the gas she uses in 13 weeks.
The cost of gas for 13 weeks, is given as,
= 4.2 × 50.1 × 13
= 2735.46 pence
Thus, the required cost of the gas as of the 13-week usage of gas is 2735.46 pence.

For every dollar Bennett spent on bagels, Dominic spent 25 cents less. Bennett
paid $12.50 more than Dominic. How much did they spend in the bagel store together?
(A) $37.50 (B) $50.00 (C) $87.50 (D) $90.00
(E) $92.50
Answer:
The answer is C:$87.50
Step-by-step explanation:
Ben - 1$
David - 0.75$
For each Bagel, Ben paid 0.25$ extra.
Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$
Then david spent = 3/4*50 = 37.5$
Total = 50+37.5 =$87.50
