Karina needs a total score of at least 627 on three games of bowling to break the league record. Suppose she bowls 222 on her first game and 194 on her second game. What score does she need on her third game to break the record?

Add 222 and 194 together; 416. Then subtract; 627 - 416 = 211. Add one because that means she got over 627. She needs to get a score of 212 to beat the record. I hope that helps!

Suppose a triangle has sides 3, 4, and 6. Which of the following must be true?

Answer with explanation:

Sides of triangle are , 3, 4 and 6.

This is an Isosceles triangle,because all the three sides are not equal to each other.

Length of Greatest Side= 6 cm

Length of other two smaller sides are 3,and 4 cm.

Sum of square of two smaller sides

    = 3²+4²

    = 9 + 16

    = 25

Square of largest side = 6²=36

36≠25

Square of largest side≠Sum of squares of two smaller sides

Pythagorean theorem not verified.

Hence ,the triangles having sides, 3, 4 and 6 is not a right triangle.

McNeary brought home a weekly pay check with these deductions: Federal--$45.67, FICA-- 24.63, state--19.04. How much does he pay annually in TOTAL deductions?

Answer:

McNeary  pays  annually in total deductions is $ 4645.68 .

Step-by-step explanation:

As given

McNeary brought home a weekly pay check with these deductions:

Federal - $45.67, FICA - $ 24.63, state - $19.04.

As there are 52 weeks in a year .

Thus

Federal deduction in one year = Federal deduction per week × Number of weeks in a year .

Put all the values in the above

Federal deduction in one year = $ 45.67 × 52

                                                   = $ 2374.84

FICA deduction in one year = FICA deduction per week × Number of weeks in a year .

Put all the values in the above

FICA deduction in one year = $ 24.63 × 52

                                              = $ 1280.76

State deduction in one year = State deduction per week × Number of weeks in a year .

Put all the values in the above

State deduction in one year = $ 19.04 × 52

                                              = $ 990.08

Thus

Total deduction in a year = Federal deduction in one year + FICA deduction in one year + State deduction in one year .

Put all the values in the above

Total deduction in a year = $ 2374.84  + $ 1280.76  + $ 990.08

                                          = $ 4645.68

Therefore McNeary  pays  annually in total deductions is $ 4645.68 .

A customer went to a garden shop and bought some potting soil for $11.50 and 9 shrubs. the total bill was $94.75. write and solve an equation to find the price of each shrub. a. 9p 11.5p = $94.75; p = $4.62 b. 9p $11.50 = $94.75; p = $11.75 c. 9p $11.50 = $94.75; p = $9.25 d. 9(p $11.50) = $94.75; p = $5.00

Let

p---------> the price of each scrub

s----------> the price of the potting soil

T--------> total bill

we know that

 T=9p+s

in this problem

 T=\$94.75\\ s=\$11.50\\p=?

substitute the values in the formula above

 \$94.75=9p+\$11.50

solve for p

 9p=94.75-11.50

 9p=83.25

 p=9.25

therefore

the answer is the option C

 \$94.75=9p+\$11.50

 p=9.25

Sergio has decided to diversify his investments in the following way:$4,000 in an account earning 3.2% simple interest$4,000 in a savings account earning 2.1% interest compounded annually$7,500 in a certificate of deposit earning 5% interest compounded quarterlyhow much total interest will sergio earn on his investments at the end of 4 years?

Answer: $1,208.28

Step-by-step explanation:

Formula we use here :-

Simple interest : I=Prt

Compound amount : A=P(1+r)^t)

Compound amount(Compounded quarterly):- A=P(1+\dfrac{r}{4})^{4t})

where P is the principal amount , r is the rate of interest( in decimal) and t is the time.

1) $4,000 in an account earning 3.2% simple interest

Simple interest : 4000\times0.032\times4=\$512

2) $4,000 in a savings account earning 2.1% interest compounded annually

Compound Amount :- A=4000(1+0.021)^4\approx\$4346.73

Compound interest : A-P=\$4346.73-\$4000=\$346.73

3) $7,500 in a certificate of deposit earning 5% interest compounded quarterly

Compound Amount :- A=4000(1+\dfrac{0.021}{4})^{4\times4}\approx\$4349.56

Compound interest : A-P=\$4349.56-\$4000=\$349.55

Now, the total interest : \$512+\$346.73+\$349.55=\$1208.28

Hence, the total interest will sergio earn on his investments at the end of 4 years = $1,208.28

A newly married couple took out a 5-year $30,000 loan for their wedding. After 5 years, they paid a total of $32,800 back to the bank. What was the interest rate on the loan?

Interest at the end of 5 years. Time = 5 years, Principal = $30000  

I = 32800 - 30000 = 2800.

Assuming simple interest.

I = PRT

2800 = 30000*R * 5

30000*R * 5 = 2800

R = 2800 /(30000*5)

R ≈ 0.018667

R ≈ 1.8667 %

Interest ≈ 1.8667% per year.

A cashier has a total of 26 bills made up of tens and hundreds the total value is 1610 how many hundreds and tens does she have?

Let the tens be x.

Therefore the hundreds will be (26 - x).      

Since they both total to 26. x  + (26 - x) = 26

10*x + 100*(26 - x) = 1610

10x  + 2600 - 100x = 1610

10x - 100x = 1610 - 2600

-90x = -990

x = -990/-90

x = 11.

So the 10s are x =11,   the 100s  are (26 -11) = 15

11 tens bills and 15 hundred bills.

Suppose you drop a ball from a window 15 meters above the ground. the ball bounces to 70% of its previous height with each bounce. What is the total number of meters (rounded to the nearest tenth) the ball travels between the time it is dropped and the eighth bounce? A. 76.4 B. 79.2 C. 32.1 D. 64.2

15

1st bounce = 0.70*15 = 10.5

2nd bounce = (0.7)*(0.7)*15 = 7.35

3rd bounce = (0.7)*(0.7)*(0.7)*15 = 5.145

4th bounce = (0.7⁴)*15 = 3.6015

5th bounce = (0.7⁵)*15 = 2.52105

6th bounce  = (0.7⁶)* 15 = 1.764735

7th bounce = (0.7⁷)*15 = 1.2353145

8th bounce = (0.7⁸)*15 = 0.86472015

Add up all:

10.5 + 7.35 + 5.145 + 3.6015 + 2.52105 + 1.764735 + 1.2353145 + 0.86472015 = 32.98231965

Between the time it was dropped and the eight bounce.

That means we need to add the first 15 m it traveled when initially dropped.

15 +  32.98231965 = 47.98231965 m.

None of the options has a value around 47.98 m.
