The length and a quarter of the width of a rectangle add up to 7 in, while the length and the width add up to 10 in. What are the rectangle’s length and width?
Answer:
The length is 6, and the width is 4.
Step-by-step explanation:
The length and width add up to 10. 6 + 4 = 10.
A quarter of the width plus the length = 7. A quarter of 4 = 1. 1 + 6 = 7
Answer:
Width is 4 inches, Length is 6 inches
Step-by-step explanation:
Let us set a variables, l for length, and w for width. Now, we can write two expressions with the given information:
1. The length, l, and one quarter of the width, w, add up to 7in. Therefore,:
l+0.25w=7
2. The length, l, and the width, w, add up to 10in. Therefore,:
l+w=10
Let us now subtract the first equation from the second to find the variable, w. When we do this, we should make sure that we are subtracting on both sides:
[tex]l+w-(l+0.25w)=10-7\\l+w-l-0.25w=3\\0.75w=3\\w= 4[/tex]
Now, let us substitute this 4 into w of the equation to obtain l:
l+w=10
l+4=10
l=6
Therefore, the width of the rectangle is 4 inches and the length of the rectangle is 6 inches.
I hope this helps! Please let me know if you have any further questions :)
2x[(-6+4)x(5+9)-3] what is the value of the expression
Answer: -62

can someone answer these 2 questions asap and thank you its also double the points because it 2 questions ;)
9:
r[tex]\leq[/tex]15.5 (not the one with the line under it i just couldnt find the one that didnt have the line under it)
for the graph, put 16 on the right side and label the lines right to left 16 15.5 14 14.5 etc. Put an open circle on the 15.5 line. then make an arrow pointing to the left.
10:
80[tex]\leq[/tex]p+64
This is because she needs 80 points OR MORE and (p represents the points) she already has 64. She needs 80 to be less than or equal to the amount of points earned.
The solution is 16[tex]\leq[/tex]p because 80-64=16 and p is needs to be greater than or equal to 16

Which of the models show 1.28 ÷ 4?
Answer:
1.28 ÷ 4 = 0.32
But the "models" make little or no sense. I can see the three bars and two dots representing the digits 3 and 2, but that is the only image I see, repeated three times. It also shows no reference to the decimal place, so I would say there is no real representation of it all.

HELP PLS!!!
Answer:
48.75$
Step-by-step explanation:
the difference is about 16.25$

More advanced explanation: $65 is the whole, find out what the 25% is.
65 - 48.75 = 16.25
$16.25 is the discount.
So rounding to the nearest cent from your options, $16.25 is 25% of $65.
That's the ending part to your answer.

C) 8 to 4
D) 8 to 5
The proportion of lemons in the lemonade is 7 while the proportion of water in the lemonade is 4.

Answer:
PA = 17
Step-by-step explanation:
The centroid is the point of intersection of the 3 medians of the triangle.
A median is is a segment that goes from one of the triangles vertices to the midpoint of the opposite side.
QA is a median , so bisects PR at A , then
PA = 0.5PR = 0.5 × 34 = 17

If you own 2.08% of stock out of 48 million outstanding stock pool then what percentage will you own for 16 million outstanding stockholders
Answer:
6.24%
Step-by-step explanation:
The first step is to determine how much stock is owned when there are 48 million outstanding stock
[tex]\frac{2.08}{100}[/tex]x 48 million = 0.9984 million
So, i own 0.9984 million shares.
If there are 16 million outstanding stock
(0.9984 / 16 million ) x 100 = 6.24%

Answer:
25/64
Step-by-step explanation:
C=πd
find diameter:
small= 15 x 15= 225
large= 24 x 24= 576
multiply:
225 x 3.14= 706.5
576 x 3.14= 1808.64
ratio:
706.5/1808.64
reduce:
25/64
Length of the radius of the small pizza = 15 inches
Circumference of the small pizza :
[tex] =\tt 2\pi r[/tex]
[tex] = \tt2 \times 3.14 \times 15[/tex]
[tex] = \tt94.2 \: inches[/tex]
Thus, the circumference of the small pizza = 94.2 inches
Length of the radius of the large pizza = 24 inches
Circumference of the large pizza :
[tex] = \tt2\pi r[/tex]
[tex]\tt2 \times 3.14 \times 24[/tex]
[tex] = \tt150.72[/tex]
Thus, the circumference of the large pizza = 150.72 inches
Ratio of the circumferences of the two pizzas :
[tex] = 94.2 : 150.72[/tex]
[tex] = \tt\frac{94.2 \times 100}{150.72 \times 100} [/tex]
[tex] = \tt \frac{9420}{15072} [/tex]
Let us simplify the fraction :
[tex] = \tt\frac{9420}{15072} [/tex]
[tex] =\tt \frac{9420 \div 12}{15072 \div 12} [/tex]
[tex] = \tt \frac{785}{1256} [/tex]
[tex] = \tt\frac{785 \div 157}{1256 \div 157} [/tex]
[tex] = \color{plum}{ \tt\frac{5}{8} }[/tex]
Thus, the ratio of their circumferences = 5:8
Therefore, the ratio of the circumferences of the pizzas as a fraction [tex] = \color{plum}{ \tt\frac{5}{8} }[/tex]
