Answer:
112 tiles
Step-by-step explanation:
Area = 28ft sq
Tiles are 1/4 each sqft
We are working cube square inside cube ft square = 1 sq /4 (for multiplier).
= 4 x 28 = 112
112 x 0.25 = 28 to check.
112 x 0.25 x 4 = 112 is the multiplier to check again.
What is the sum of the measures of the exterior angles of this triangle?
A triangle has angles A, C, 51 degrees. Angle A has exterior angle B and angle C has an exterior angle with measure of 112 degrees.
The measure of ∠B is 119°.
What is the exterior angle?An exterior angle is a measure of rotation between one extended side(we extend it virtually) of the polygon with its adjacent side which is not extended.
All the exterior angles are of the same measure, and therefore, their measure is (360/n)°.
The angle adjacent to 112° will form a straight angle along with 112° adding to 180° which makes ∠C=68°
Then;
a+c+51°= 180°
a+68°+51° = 180°
a+119° = 180°
a = 180° - 119°
a = 61°
Now,
a+b = 180°
61+b = 180
b = 180-61
b = 119°

the lateral area of a cone is 558pi cm^2 the radius is 31 cm. find the slant height to the nearest tenth
The slant height of the cone is 39.7 cm
Explanation:
Given:
Lateral surface area of a cone = 558π cm²
Radius, r = 31 cm
Slant height, l = ?
We know:
[tex]A = \pi r\sqrt{h^2+r^2}[/tex]
Where,
h is the height of the cone
r is the radius
Solving the equation further:
[tex]558\pi = \pi r\sqrt{h^2+r^2} \\\\558 = 31\sqrt{h^2+(31)^2} \\\\(18)^2 = h^2 + 961\\\\324 = h^2+ 961\\\\h = 25.23[/tex]
Lateral height, H = ?
Applying pythagoras theorm,
(H)² = (h)² + (r)²
(H)² = (25.23)² + (31)²
(H)² = 636.55 + 961
(H)² = 1597.55
H = 39.7 cm
Therefore, the slant height of the cone is 39.7 cm
Which figure represents the image of trapezoid LMNP after a reflection across the x-axis?
A) figure A
B) figure B
C) figure C
D) figure D
Answer:
A
Step-by-step explanation:
Imagine folding the graph in half on the x-axis and tracing the shape on the other side.
Ps. x-axis is horizontal (left-right), y-axis is vertical (up-down)
The figure that represents the image of trapezoid LMNP after a reflection across the x-axis is the figure A
How to determine the figure?From the figure, we can see that the trapezoid LMNP is the second quadrant.
A reflection across the x-axis will place the trazpezoid in the third quadrant
The figure A is in the third quadrant
Hence, the figure that represents the image of trapezoid LMNP after a reflection across the x-axis is the figure A

bob needs to be at school by 7:00 it takes him 1 hour and 21 minutes to get there. his morning routine takes 30 minutes. what time should bob leave the house
Answer:
5:00
Step-by-step explanation:
1 hour 21 minutes = 1,35 hours
30 minutes = 0,5 hours
1,35-0,5=0,85 hours he needs to get to school
7-0,85=6,15
6,15 = 6 hours 9 minutes
In 6 hours 9 minutes he needs to leave the house
You and TWO of your closest friends went to a restaurant for dinner. The bill came to $25.60. You want to split the bill EQUALLY and leave a 20% tip. How much does each person owe? (Show Work.)
A: $5.12
B: $8.53
C: $10.24
Answer:
C
Step-by-step explanation:
Since they left a tip of 20% you find 20% of 25.60, and then add it to 25.60.
You add 5.12 and 25.60 because it was a tip, they gave that much more.
So 20% which is 5.12.
25.60 + 5.12 = 30.72
since there were 3 people in total you just divide
30.72 / 3
= 10.24
What is the image of (4,-7) after a reflection over the y-axis?
Answer:
It would be a point which is at (-4,-7).
The image of the point (4,-7) after a reflection over the y-axis is (-4,-7). This happens because the y-axis is the axis of symmetry during a reflection over this axis, changing the x-coordinate's sign while keeping the y-coordinate constant.
Explanation:The image of a point after a reflection over the y-axis results in the x-coordinate of the point changing its sign. Therefore, the image of the point (4,-7) after a reflection in the y-axis would be (-4,-7). In other words, you move the point 4 units to the left across the y-axis while the y-coordinate remains unchanged.
This process is derived from the concept that the y-axis is the axis of symmetry in a reflection over the y-axis. As such, points on one side of the axis are mirrored on the other side, changing only the sign of the x-coordinate and keeping the y-coordinate constant.
A helpful way to visualize this is by drawing a coordinate grid and plotting the point (4,-7). By reflecting this point over the y-axis, you will see it lands at the point (-4,-7).

Sandy spent half of her allowance going to the movies. She washed the family car and earned 8 dollars. What is her weekly allowance if she ended with 13 dollars ?
Answer:
I hope this helps (๑¯◡¯๑)
To find Sandy's allowance, we use the given information to set up an equation. After solving it, we determine that Sandy's weekly allowance is $10.
To determine Sandy's weekly allowance, we need to work backward from the information given. We know that she ended with $13 after spending half of her allowance on movies and earning an additional $8 from washing the car. Let's let the variable A represent Sandy's allowance. According to the problem, Sandy spent A/2 on movies, and when she added the $8 she earned, she had $13.
We can set up the equation as follows:
(A/2) + 8 = 13Now, we solve for A to find the allowance:
A/2 = 13 - 8A/2 = 5A = 5 * 2A = $10So, Sandy's weekly allowance is $10.

Tyler's grocery receipt shows a charge of $0.25 for every apple he purchased.
Let g represent the amount on the grocery receipt.
Let a represent the number of apples purchased
Which is the independent variable?
the amount of the grocery bill
the cost of an apple
the weight of the apples
the number of apples purchased
The number of apples Tyler purchased is the dependent variable.
What is a variable?The alphabetic character that expresses a numerical value or a number is known as a variable in mathematics.
A representation of an unknown numerical value in an equation or algebraic statement by a symbol, typically a letter. A variable can be defined as a quantity that is changeable and not fixed.
Given:
Tyler’s grocery receipt shows a charge of $0.25 for every apple he purchased.
'g' represent the amount on the grocery receipt.
'a' represent the number of apples purchased.
Therefore, 'a' is the variable here.
So, the amount of apple is independent variable but the purchased values if dependent variable.
Thus, the number of apple Tyler purchased is the dependent variable.

#SPJ6
Final answer:
The independent variable is the number of apples purchased, as it determines the dependent variable, which is the total amount spent on apples in the grocery bill.
Explanation:
The independent variable in this scenario is the number of apples purchased (represented by a). This is because the independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In this case, Tyler decides how many apples to buy, and that decision directly affects the total cost, which is the dependent variable (g). The price of an apple, the weight of the apples, and the amount on the grocery bill are all dependent on the number of apples Tyler chooses to purchase. To find the total amount spent on apples, one would multiply the number of apples purchased by the cost per apple.

Given:
It is given that LON is a straight line. The measure of ∠LOM = (4x + 30)° and the measure of ∠MON = (8x + 90)°
We need to determine the value of m∠MON
Value of x:
Since, LON is a straight line and the angles LOM and MON are linear pairs of angles.
Since, linear pair of angles add up to 180°
Thus, we have;
[tex]\angle LOM+\angle MON=180^{\circ}[/tex]
Substituting the values, we get;
[tex]4x+30+8x+90=180[/tex]
[tex]12x+120=180[/tex]
[tex]12x=60[/tex]
[tex]x=5[/tex]
Thus, the value of x is 5.
Value of m∠MON:
The measure of ∠MON can be determined by substituting x = 5 in the expression (8x + 90)°, we have;
[tex]m\angle MON=(8(5)+90)^{\circ}[/tex]
[tex]m\angle MON=(40+90)^{\circ}[/tex]
[tex]m\angle MON=130^{\circ}[/tex]
Thus, the measure of ∠MON is 130°

Two numbers have a product of 6800 and a difference of 5 what are the two numbers
Answer:
80 and 85
Step-by-step explanation:
Let a and b be those numbers
a*b = 6800
a - b = 5
Use the substitution method.
a = 5 + b
(5 + b)*b = 6800
5b + b*b = 6800
bb + 5b - 6800 = 0
b = -5/2 + root(25 - 4*1*(-6800)) /2
b = -5/2 + 165/2
b = 80
or b = - 85
a - b = 5
a - 80 = 5
a = 85
