To find the height the ladder reaches up the wall, set up a proportion using similar triangles and Catie's height as the ladder's height. The estimate for the ladder's height up the wall is 6.8 feet.
Given information:
Catie is 5 feet 6 inches tall.Her feet are 16 inches from the ladder's base.The ladder's base is 4.5 feet from the bottom of the wall.To find the height the ladder reaches up the wall, we can set up a proportion using similar triangles. Catie's height can be considered as the ladder's height, and the distance on the wall can be related to the ladder's base and height.
Using the information provided and performing the calculations, the estimate for the height the ladder reaches up the wall would be approximately **6.8 feet** to the nearest tenth of a foot.
A line passes through the point (–7, 5) and has a slope of 1/2. Which is another point that the line passes through?
(–13, 9)
(–9, 13)
(9, 13)
(13, 9)
Answer:
Option C is correct.
Another point is, (9, 13)
Step-by-step explanation:
Point slope form states the equation of a straight line in the form [tex]y-y_1=m(x-x_1)[/tex]; ......[1]
where
m is the slope of the line and
[tex](x_1, y_1)[/tex] are the coordinates of a given point on the line.
As per the given condition we have;
[tex](x_1, y_1)[/tex] = (-7, 5)
Slope(m) = 1/2
then; substitute these in [1] we have;
[tex]y -5 = \frac{1}{2}(x-(-7))[/tex]
or
[tex]y -5 = \frac{1}{2}(x+7)[/tex]
Using distributive property; [tex]a\cdot(b+c) = a\cdot b + a\cdot c[/tex]
[tex]y-5= \frac{1}{2}x+\frac{7}{2}[/tex]
Add 5 on both sides we get;
[tex]y=\frac{1}{2}x+\frac{7}{2} + 5[/tex]
Simplify:
[tex]y= \frac{1}{2}x+\frac{17}{2}[/tex]
Only option which satisfy the above line equation is (9, 13).
Check:
put x = 9 and y = 13
[tex]13= \frac{1}{2}(9)+\frac{17}{2}[/tex]
[tex]13=\frac{9}{2}+\frac{17}{2} =\frac{26}{2} = 13[/tex] True.
Therefore, the another point that the line passes through is, (9, 13)

Charlie wants to order lunch for his friends. He'll order 5 sandwiches and a $3 kid's meal for his little brother. Charlie has $28. How much can he spend on each sandwich if they are all the same price? Choose two answers: one for the inequality that models this situation and one for the correct answer.
The inequality 5x + 3 ≤ 28 represents the situation and each sandwich cost is $5.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
Let x be the cost of each sandwich.
5 sandwich costs = 5x
$3 kid's meal for his little brother.
Total cost = 5x + 3
5x + 3 = 28
5x = 25
x = $5
The inequality:
5x + 3 ≤ 28
Thus, the inequality 5x + 3 ≤ 28 represents the situation and each sandwich cost is $5.

The measure of an exterior angle of triangle is equal to the sum of measures of two interior angles of triangle that are not supplementary with this exterior angles.
In the case of this question this fact sounds as
m∠XBC = m∠BAC + m∠BCA (option 1).
Now if
m∠XBC=(3p-6)°m∠BAC=(p+4)°m∠BCA=84°,then
3p-6=p+4+84 (option 2),
3p-6=p+88 (option 3),
3p-p-6=p-p+88,
2p-6=88 (option 4),
2p-6+6=88+6,
2p=94 (option 5),
p=47.
Then m∠XBC=(3p-6)°=(3·47-6)°=135°.
Answer: m∠XBC=135°.

Compare the fraction by using the symbol < , <, or =. a. 4⁄9 _____ 5⁄9 b. 4⁄5 _____ 8⁄10 c. 7⁄12 _____ 7⁄15 d. 3⁄4 _____ 6⁄7
Final answer:
To compare fractions, evaluate if they are equal or if one is greater by comparing the numerators and denominators.
a. 4/9 < 5/9
b. 4/5 = 8/10
c.7/12 > 7/15
d.3⁄4 < 6⁄7
Explanation:
In fractions, to compare two fractions, check if the fractions are equal, or if one is greater than the other by comparing the numerators and denominators.
a. 4/9 vs. 5/9: 4/9 < 5/9 since 5 is greater than 4.
b. 4/5 vs. 8/10: 4/5 = 8/10 since they are both equivalent fractions.
c. 7/12 vs. 7/15: 7/12 > 7/15 since 12 is greater than 15.
d. 3/4 vs. 6/7: 3⁄4 < 6⁄7 because converting to decimals, 3⁄4 is 0.75 and 6⁄7 is approximately 0.857, making 6⁄7 larger.

Find the amount paid for the loan.
$2400 at 10.5% for 5 years
Final answer:
$3,919.24
Explanation:
To calculate the total amount paid for a loan of $2,400 at an interest rate of 10.5% over 5 years, we will assume the interest compounds annually for simplicity. The formula to find the future value of a loan including interest is P(1 + r)^n, where P is the principal amount ($2,400), r is the annual interest rate (10.5% or 0.105), and n is the number of years (5).
Plugging the numbers into the formula gives us $2,400(1 + 0.105)^5. Calculating this gives us approximately $3,919.24. Therefore, the total amount paid for the loan over 5 years would be $3,919.24.
To find the amount paid on a $2400 loan at 10.5% interest for 5 years, calculate the simple interest and add it to the principal. The total interest is $1260, bringing the total repayment amount to $3660 over 5 years.
To find the amount paid for the loan of $2400 at 10.5% interest for 5 years, one would typically use the formula for the compound interest or an installment payment plan depending on whether the loan is paid off in a lump sum at the end of the term or through regular payments over the term. However, you have not specified the method of repayment (lump sum or installments), so let's consider a simple interest scenario which is often used for short-term loans.
The simple interest can be calculated as:
I = PRT
Where:
Using the formula:
I = $2400 × 0.105 × 5 = $1260
Therefore, the total interest paid over 5 years is $1260. To find the total amount paid for the loan, add the interest to the principal:
Total Amount Paid = Principal + Interest
Total Amount Paid = $2400 + $1260 = $3660
The borrower would have to pay a total of $3660 after 5 years.

What is the rule for the reflection?
Will mark brainliest!
Answer:
Option C is correct.
[tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]
Step-by-step explanation:
From the given figure:
Coordinate of Triangle ABC are:
A(-2, 1), B(-3, 4) and C(-4, 1)
And
Coordinate of Triangle A'B'C' are:
A'(1, -2), B'(4, -3) and C'(1, -4)
The rule of reflection across the line:
[tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]
then;
Apply the given rule of reflection on coordinate of triangle ABC
[tex]A(-2, 1) \rightarrow (1, -2) =A'[/tex]
[tex]B(-3, 4) \rightarrow (4, -3) =B'[/tex]
[tex]C(-4, 1) \rightarrow (1, -4) =C'[/tex]
Therefore, the rule of reflection used here is [tex]r_{y=x} (x, y) \rightarrow (y, x)[/tex]

The more surface area an ice cube has, the more quickly it melts to cool a beverage. mark states that the ideal ice cube would be a prism that is a perfect cube of dimensions 2 by 2 by 2. denise thinks that the prism should be more flat, with dimensions of 1 by 2 by 4. which rectangular prism gives the greatest surface area, making for a better ice cube?
Answer: D
Step-by-step explanation:
Denise Rectangular prism gives the greatest surface area, making for a better ice cube.
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
The surface area of a rectangular prism can be calculated by adding up the areas of all six faces.
The surface area of a prism with dimensions l, w, and h is given by:
A = 2lw + 2lh + 2wh
For Mark's prism (2 by 2 by 2), the surface area is:
A = 2(2 × 2) + 2(2 × 2) + 2(2 × 2)= 24
For Denise's prism (1 by 2 by 4), the surface area is:
A = 2 (1 × 2) + 2 (1 × 4)+ 2 (2 × 4)= 28
So both prisms have the different surface area of 24 square units and 28 square units.
Hence, Denise rectangular prism gives the greatest surface area, making for a better ice cube

the function f(x)=2^x and g(x)=f(x)+k. if k=2, what can be concluded about the graph?
the graph of g(x) is shifted vertically...
2 units to the left of the graph of f(x)...
Answer:
Its shifted verticlly 2 and to the left 2.
Step-by-step explanation:
Its verticlly because when it says 2^x its going up if it said -2^x it would go down.
It goes left because it is 2^x=? so if you put it on the other side its negative which makes it to the left.
