1. In a triangle∆ABC, if DE is parallel to BC, AD
DB

4
and AC = 15 cm, then the length AE is:
(a) 45 (b) 23/7 (c) 1 (d) 45/7
The length of the segment AE on the triangle is 45/7
How to determine the length of AE?From the question, we have the following parameters that can be used in our computation:
DE parallel to BC,
Also, we have
AD/DB=3/4
The above parameters mean that
AD/AB = AE/AC
Also, we know that
AB = AD + DB
From the ratio values, we have
AB = 3 + 4
Evaluate the sum
AB = 7
Updating the initial ratio, we have
AE/15 = 3/7
Multiply both sides by 15
So, we have the following representation
AE = 15 * 3/7
Evaluate the products
AE = 45/7
Hence, the length of AE is 45/7

The value of x is 18 if ∠C and ∠D are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.
What are vertically opposite angles?
It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.
It is given that:
∠C and ∠D are vertical angles.
5x-7 = 8x-55
Subtract 5x from both sides:
-7 = 3x -55
Add 55 to both sides:
3x = 48
x = 48 /3
x = 16
Thus, the value of x is 18 if ∠C and ∠D are vertical angles. m∠C = 5x - 7 and m∠D = 8x – 55.

Suppose that your unsubsidized Stafford loans plus accumulated interest total $ 35000 at the time you start repayment, the interest rate is 6% APR, and you elect the standard repayment plan of a fixed amount each month for 10 years. What is your monthly repayment?
Repayment amount =
How much will you pay in interest?
Interest paid =
a) The monthly repayment amount is $466.67.
b) The total interest paid on loan is $21,000.
How is interest on student loans computed?Interests on student loans are computed using the simple interest system, instead of compound interest.
The total interest payable is a function of the outstanding balance (principal amount plus accumulated interest) during the non-payment period, the interest rate, and the number of years of payment.
Unsubsidized Loans plus Accumulated Interest = $35,000
Interest rate (APR) = 6%
Repayment period = 120 months (10 years x 12)
Interest on the student loan = $21,000 ($35,000 x 6% x 10)
Total amount to repay for 10 years = $56,000
Monthly repayment = $466.67 ($56,000 ÷ 120)
Thus, the monthly repayment will be $466.67, which is determined by adding the total interest for 10 years to the outstanding balance and dividing the result by 120 months.

Determine the degree measure of one angle of a 45-sided regular polygon.
The measure of an interior angle (in degrees) of an [tex]n[/tex]-sided regular polygon is [tex]\frac{180(n-2)}{n}[/tex].
[tex]n=45 \implies \frac{180(n-2)}{n}=\boxed{172^{\circ}}[/tex]
The degree measure of one angle of a 45-sided regular polygon is 172°.
What is an angle measure?When two lines or rays intersect at a single point, an angle is created. The vertex is the term for the shared point. An angle measure in geometry is the length of the angle created by two rays or arms meeting at a common vertex.
Here, the polygon has 45 sides.
To find the measure of an interior angle of a regular polygon,
we make use of the formula for each angle = (n - 2) × 180 / n.
The formula calculated is only valid in cases of regular-sided polygons.
n = 45 substituting the value of n to the formula.
(n - 2) × 180 / n
= 180 ( 45-2) / 45
= 180 x 43 / 45
= 7740 / 45
= 172°
Therefore, the measure of one angle is 172°.

When t=5 years ,A = $2023.3When t = 10 years, A = $2729.1When t = 486 months, A = $16935What is meant by compound interest?We would use the following formula to calculate compound interest:
A = P(1 + r / n) nt
Where
A is the CD's total value after t years.
The interest rate is represented by r.
The periodic interval at which it was compounded is represented by n.
P stands for the principal, or the amount of the CD purchase.
Considering the data provided,
P = 1500
r = 6% = 6/100 = 0.06
Since it was compounded 12 times in a year, n = 12.
The phrase changes.
A = 1500(1+0.06/12)^12 × t
A = 1500(1+0.005)^12t
A = 1500(1.005)^12t
1) If t is five years,
A = 1500(1.005)^12 × 5
A = $2023.3
2) If t equals ten years,
A = 1500(1.005)^12 × 10
A = $2729.1
3) If t equals 486 months, then 486/12 is 40.5 years.

b) If there are 1 440 people altogether, find the number of women.
The ratio of the number of men to women to adults is 5 : 3 : 4 and the number of women is 360
The ratio of the number of men to women to children.From the question, we have the following ratios that can be used in our computation:
Men : Women = 5 : 3
Children : Adults = 1 : 2
This means that
Children : Men : Women = 1 : 2(Men : Women)
So, we have the following representation
Children : Men : Women = 1 : 2(5/8 : 3/8)
Open the brackets
Children : Men : Women = 1 : 5/4 : 3/4
Multiply through by 4
Children : Men : Women = 4 : 5 : 3
Rewrite the ratio as
Men : Women : Children 5 : 3 : 4
The number of women in the paradeHere, we have
People = 1440
Recall that
Men : Women : Children 5 : 3 : 4
So, we have
Women = 3/(5 +3 + 4) * 1440

Evaluating a regression model: A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y = − 0.693 ⋅ x + 28.802 , with an R-squared value of 0.571536. Assume the model indicates a significant relationship between hours of TV watched and the number of situps a person can do. Use the model to predict the number of situps a person who watches 6 hours of TV can do (to one decimal place).
The predicted number of sit-ups for a person who watches 6 hours of TV is 24.644.
The given results of regression:
y = –0.693x + 28.802
The formula for regression equation is:
y = ax + b
So, given that:
a = –0.693
b = 28.802
r2 = 0.571536
r = 0.756
Back to the given results of regression:
y = –0.693x + 28.802
In this case, y represents the number of sit-ups a person can do, and x represents the hours of TV watched per day.
Thus, the predicted number of sit-ups for a person who watches x = 6 hours of TV is:
y = –0.693x + 28.802
y = –0.693 * 6 + 28.802
y = –4.158 + 28.802
y = 24.644
Hence, the predicted number of sit-ups for a person who watches 6 hours of TV is 24.644.

PLEASE HELP ME WITH THIS QUESTION
Draw an example of a polynomial with
-Degree of 5
-Positive lead coefficient
-Zeros at -5, -2, 0, 3, 6
The required polynomial is x⁵ - 2x⁴ - 35x³ + 36x² + 180x.
What is a polynomial?A polynomial is an algebraic expression.
A polynomial of degree n in variable x can be written as,
a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² +...+ aₙ.
Given, We have to construct a polynomial of degree 5, a positive lead
co-efficient and zeros or roots are -5, -2, 0, 3, 6.
If roots are -5, -2, 0, 3, 6 factors are (x + 5), (x + 2), (x + 0), (x - 3), (x - 6).
∴The required polynomial is (x + 5)(x + 2)(x + 0)(x - 3)(x - 6).
= x(x + 5)(x + 2)(x - 3)(x - 6).
= (x² + 5x)(x² - 3x + 2x - 6)(x - 6).
= (x² + 5x)(x² - x - 6)(x - 6).
= (x² + 5x)(x³ - 6x² - x² + 6x -6x + 36).
= (x² + 5x)(x³ - 7x²+ 36).
= x⁵ - 7x⁴ + 36x² + 5x⁴ - 35x³ + 180x.
= x⁵ - 2x⁴ - 35x³ + 36x² + 180x.

solve inequality pls
Answer:
is there a pitcher with it
Step-by-step explanation:
A recipe requires 1 1/4 cups of sugar for every 1/3 of a cup of salt. What is the unit rate of salt to sugar in the recipe?
Answer:
3 3/4 cups of sugar per cup of salt
Step-by-step explanation:
To find the unit rate of salt to sugar in the recipe, we need to divide the number of cups of sugar by the number of cups of salt. In this case, the unit rate of salt to sugar is 1 1/4 cups of sugar divided by 1/3 of a cup of salt, which can be simplified to 3 3/4 cups of sugar per cup of salt.
Answer:
The unit rate of cups per teaspoon is 1 1/3
Step-by-step explanation:
-A recipe calls for 2 by 3 cup of sugar for every 1 by 2 teaspoon of vanilla.
Based on the above information, the calculation is as follows:
=(2/3)/(1/2)
=(2/3)/(1/2)
=(2/3)x(2/1)
=(2x2)/(3x1)
=(4/3)
= 1 1/3
Type the expression as a radical.
Step-by-step explanation:
in a fraction as exponent the numerator defines the pure exponent of the base, and the denominator gives the degree of root of the base.
so, this is
[tex] \sqrt[5]{y^{3} } [/tex]
Answer:
[tex] \sqrt[5]{ {y}^{3} } [/tex]
Step-by-step explanation:
When converting an expression with a fractional exponent to its radical form, the base number goes inside the radical(which means it becomes the radicand) along with the numerator(which remains an exponent). Whereas the denominator of the exponent becomes the index, or what dictates whether the radical is a square root, cube root, etc.
EX:
[tex] {y}^{ \frac{a}{m} } = \sqrt[m]{ {y}^{a} } [/tex]
