John is two years younger than his sister, Annie. Last year, John was half Annie's age. How old are John and Annie now?
Answer: John is 3 and Annie is 5

Answer: John is 3 and Annie is 5
Step-by-step explanation:
Half of 4 is 2 so last year John was 2 and Annie 4 and like a year has passed we add 1 to 2 and 4 which helps us determine that John is now 3 and Annie 5

The student council has $800 to spend on homecoming t-shirts. The number of t-shirts they can buy is a function of the price of the price of the t-shirt p, in dollars, given by n(p)= 800 over p.
Answer:
the price of the t-shirt is inversely proportional to the number of t-shirts to be bought.
Step-by-step explanation:
The total amount to be spent on t-shirts is $800.
The function;
n(p) = 800 / p (price in dollars)
as the price per shirt increases, the number of shirt decreases and the curve moves down towards zero. When the price per shirt decreases, the number of shirt increases moving the curve upwards to infinity

What is the constant term in the expression 6x3y + 7x2 + 5x + 4?
Answer:
4
Step-by-step explanation:
Given algebraic expression: 6x^3y+7x^2+5x+46x3y+7x2+5x+4
We know that the constants are the terms in the algebraic expression that contain only numbers.
In the given expression only last term has only numerical value and no variable, rest of them have variable x.
Therefore, the constant term in the given algebraic expression 6x^3y+7x^2+5x+46x3y+7x2+5x+4 is
Two rectangular picture frames have the same area of 45 square inches but have different side lengths. Frame A has a length of 6 inches, and Frame B has a length of 7 inches. 1. Without calculating, predict which frame has the shorter width. Explain your reasoning. 2. Find the width that you predicted to be shorter. Show your reasoning.
9514 1404 393
Answer:
1. the longer frame (B) has the shorter width
2. the shorter width is 6 3/7 inches, area divided by length
Step-by-step explanation:
The relation between area, length, and width is ...
A = LW
Then the width is ...
W = A/L . . . . . inversely proportional to length
__
1. Since length and width are inversely proportional (when area is constant), the shorter width will be associated with the longer length. Frame B will have the shorter width.
__
2. The width of frame B is ...
W = A/L = (45 in²)/(7 in) = 45/7 in = 6 3/7 in

Answer:
A, 14
Step-by-step explanation:
Assuming that she has a total of d dollars, and spends half of it, then we have 1/2d. She then spends another 6 dollars, and therefore we would subtract. She is left with one dollar.
1/2d-6=1
Working backwards, we can solve for d, her total amount of money:
1/2d=7
d=14

help plz. full working out
Answer:
£ 186.20
Step-by-step explanation:
height = 6 cm = 0.06 m
Volume of gravel drive away = length * width * height
= 11 * 4 * 0.06
= 2.64 m³
Number of gravel bags needed = 2.64 ÷ 0.4
= 6.6
7 bags are to be purchased by him.
Cost of a bag = £ 38
Cost of 7 bags = 38 * 7 = £ 266
Discount = 30% of 266
[tex]= \frac{30}{100}*266[/tex]
= £ 79.80
Amount paid by Martin = 266 - 79.80
= £ 186.20
trigonometry help- double angle formulae
Step-by-step explanation:
We have sinA = 4/5 and sinB = 7/25.
=> cosA = sqrt(1 - sin²A) = 3/5
=> cosB = sqrt(1 - sin²B) = 24/25
P.S. Cosine must be positive in Quadrant I.
sin(A - B)
= sinAcosB - cosAsinB
= (4/5)(24/25) - (3/5)(7/25)
= 75/125 = 3/5. (Shown)
