Can someone help me?
Answer:
Step-by-step explanation:
Because these two triangles are isoceles triangles, two angles are the same, which in this case would be 78. 78 times 2 would give us 156 for the right triangle, but since 180 - 156 does not equal 16, they are not similar nor congruent.

What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The temperature at the time of bed.
Initial temperature = 36° F
The temperature when she woke up.
Final temperature = -9° F
The change in temperature.
= Final temperature - Initial temperature
= -9 - 36
= 45°F
This means that there was a change of 45°F from the time when she went to bed till the time she woke up.
Thus,
The change in temperature is -45°F

Answer:
The answer to the question provided is Grace.
Step-by-step explanation:
The angle measure for 60 degrees and its corresponding side which measures 14 is greater than the measure of 50 degrees and its corresponding side which measures 12.4. That's correct. The reason Hector was incorrect is because the angle measure for 60 degrees and its corresponding side measured 12.4 was less than the measure of 50 degrees and its corresponding side that measured 14. 60 degrees is greater than 50 degrees, then the corresponding side for the angle that measures 60 degrees should be greater than the corresponding side for the angle that measures 50 degrees.
A manufacturer of chocolate chips would like to know whether its bag filling machine works correctly at the 432 gram setting. It is believed that the machine is underfilling the bags. A 29 bag sample had a mean of 425 grams with a standard deviation of 26. Assume the population is normally distributed. A level of significance of 0.02 will be used. Find the P-value of the test statistic. You may write the P-value as a range using interval notation, or as a decimal value rounded to four decimal places.
Answer:
-2.154
Step-by-step explanation:
We are given;
Population mean; μ = 432
Sample mean; x¯ = 425
Sample size; n = 29
standard deviation; σ = 26
Hypothesis is defined as;
Null hypothesis; H0: μ ≥ 432
Alternative hypothesis: Ha: μ < 432
Formula for the test statistic since sample size is less than 30 is;
t = (x¯ - μ)/(σ/√n)
Plugging in the relevant values;
t = (425 - 432)/(26/√29)
t = -1.45
Now,we are given significance level of 0.02; our DF = n - 1 = 29 - 1 = 28
From t-table attached, we can see that at DF of 28 and significance value of 0.02, the critical value is 2.154
However, this is a left tailed test as the rejection region is to the left.
Thus, the critical value of a left tailed test is negative. Thus, in this case our critical value will be -2.154
Which function is the inverse of f(x) = -5x -4?
Answer:
f^-1(x) = (x + 4) / -5
Step-by-step explanation:
f(x) = -5x - 4 Substitute f(x) with y
y = -5x - 4 Switch the x and y variables
x = -5y - 4 Solve it down
x + 4 = -5y
y = (x + 4)/ -5
f^-1(x) = (x + 4) / -5 <----- This is the answer
What is the simple interest paid to the nearest cent for each principal interest rate and time $1,000, 5%, 2 years
Step-by-step explanation:
SI=prt
p=1000
r=0.05

SI=1000×0.05×2
SI=100
The simple interest paid to the nearest cent for each principal interest rate and time $1,000, 5%, 2 years is $100.
What is simple interest?Simple interest is a method of calculating the interest charge. Simple interest can be calculated as the product of principal amount, rate and time period.
Simple Interest = (Principal × Rate × Time) / 100
[tex]I = \dfrac{P \times R \times T}{100}[/tex]
Given;

3. x ≈ 16.64
Step-by-step explanation:
The tangent function relates an angle to the opposite and adjacent sides of a right triangle:
Tan = Opposite/Adjacent
Here, we're looking for the measure of the side opposite the angle, so we can rearrange this relation to ...
Opposite = Adjacent×Tan

what is the answer to this word equation? h +(2h - 1000) = 4400
Answer:
h+2h−1000=4400
Step 1: Simplify both sides of the equation.
h+2h−1000=4400
h+2h+−1000=4400
(h+2h)+(−1000)=4400(Combine Like Terms)
3h+−1000=4400
3h−1000=4400
Step 2: Add 1000 to both sides.
3h−1000+1000=4400+1000
3h=5400
Step 3: Divide both sides by 3.
3h3=54003
h=1800
Answer:
h=1800
Answer:
h = 1800
Step-by-step explanation:
Equations
Solve the following equation:
h + (2h - 1000) = 4400
Remove the parentheses. No changes are done because it doesn't have any operation of multiplication or division:
h + 2h - 1000 = 4400
Joining like terms on the left side:
3h - 1000 = 4400
Adding 1000:
3h = 5400
Dividing by 3:
h = 5400/3 = 1800
h = 1800

The function t relates the age of a plant fossil, in years, to the percentage, c, of carbon-14 remaining in the fossil relative to when it was alive.
t(c)=-3,970(ln c)
Use function t to complete the statements.
A fossil with 47% of its carbon-14 remaining is approximately ___ years old.
A fossil that is 7,000 years old will have approximately ___ of its carbon-14 remaining.
Applying the logarithmic function, it is found that:
A fossil with 47% of its carbon-14 remaining is approximately 2997 years old.A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.The age of a fossil with a proportion c of carbon 14 remaining is given by:
[tex]t(c) = -3970\ln{c}[/tex]
If the fossil has 47% of carbon-14 remaining, we have that [tex]c = 0.47[/tex], and thus:
[tex]t(0.47) = -3970\ln{0.47} = 2997[/tex]
For a fossil that is 7000 years old, we have that [tex]t(c) = 7000[/tex], and hence:
[tex]t(c) = -3970\ln{c}[/tex]
[tex]\ln{c} = -\frac{3970}{7000}[/tex]
[tex]e^{\ln{c}} = e^{-\frac{3970}{7000}}[/tex]
[tex]c = 0.5671[/tex]
A fossil that is 7,000 years old will have approximately 56.71% of its carbon-14 remaining.
